That Devourer just divided to fly that three incisive bone spears, among spears of the blade Devil Flame shoots from the rear area, one passed through its head to blast open, blasted open the forehead of that Devourer directly. 那头吞噬者刚刚将那三道尖锐的骨刺劈飞,一刀魔炎之矛间从后方射来,一下贯穿了它的头颅炸裂开来,将那头吞噬者的头部直接炸裂。 „Congratulated you to promote 62 levels, obtained two point free Enhancers points.” “恭喜您升级到了62级,获得两点自由强化点数。” Yue Zhong one kills that first 70 levels of Devourer , a big group miraculous glow submerges his within the body, helping him be promoted and obtain Enhancers once more. 岳重一将那头70级的吞噬者干掉,一大团灵光没入他的体内,让他再次晋级并且获得了强化。 Yue Zhong rapid Enhancers two Agility, a dangerous incomparable feeling instantaneously has then given birth, his point, crazy goes to retreat. 岳重迅速的强化了两点敏捷,然后一股危险无比的感觉瞬间生出,他脚下一点,疯狂的向后退去。 Sees only crowded in that such as the sea common corpse group, suddenly leapt a leader rank has reached as high as 70 levels of Devourer speeds away toward here 只见在那密集如海一般的尸群之中,突然跃出了一头头等级高达70级的吞噬者向着这边疾驰而来 That reaches as high as 70 levels of Devourer under Corpse Sea shield that in Common zombies forms, had has destroyed Strength of tank. Although they are still not able to destroy outer layer Armor of tank directly, but can actually tear the roof panel of tank, creates the attack to inside tank soldier. 那高达70级的吞噬者在普通丧尸形成的尸海掩护之下,已经有了摧毁坦克的力量。它们虽然依然无法正面摧毁坦克的外层装甲,可是却能够撕裂坦克的顶盖,对里面的坦克兵造成打击。 Saw 70 levels of Devourer that these leap suddenly, in all Armor soldier hearts have had a fear, these monsters link unexpectedly during the tank protects the tank soldiers to kill, making them not have the security sense very much. Must know that in the past, tank in the corpse group is invincible existence, even if not use the main artillery, does not have no zombies to resist the charges and roller compactions of these tanks. 看到那些突然跃出的70级吞噬者,所有的装甲兵心中都生出了一丝恐惧,那些怪物竟然连在坦克守护之中的坦克兵都能够干掉,让他们很没有安全感。要知道,在过去,坦克在尸群之中就是无敌的存在,纵然不动用主炮,也没有什么丧尸能够抵挡那些坦克的冲锋和碾压。 That follows to open fire in the tank later Twenty three infantry combat vehicles, 25 millimeters machinegun crazy fell in torrents the massive shells to go toward these 70 levels of Devourer bombardments. 那跟在坦克之后的二十三辆步兵战车纷纷开火,25毫米的机关炮疯狂的倾泻出了大量的炮弹向着那些70级的吞噬者轰击而去。 Under that crowded machinegun shell bombardment, massive zombies were rumbled to result in the pulp directly. many 70 levels of Devourer in the body by the shell bang of that machinegun were also flown upside down. 在那密集的机关炮炮弹轰击之下,大量的丧尸直接被轰得稀巴烂。不少70级的吞噬者也被那机关炮的炮弹轰中身体倒飞出去。 Fearful appeared, after body of these 70 levels of Devourer by that 25 millimeters machinegun flourishing bang, although flies upside down, but they actually quick crawled from the ground, directly continued to charge toward here, that 25 millimeters machinegun was unable to cause any effective damage to them unexpectedly. 只是可怕的一幕出现了,那些70级的吞噬者被那25毫米的机关炮蕃轰中身体之后虽然倒飞出去,可是它们却很快从地上爬了起来,径直的向着这边继续冲锋了过来,那25毫米的机关炮竟是对它们无法造成任何的有效伤害。 „Bombing!! Bombing!!” “炮击！！炮击！！” 19 tanks of that surviving also start to bomb toward these Devourer with the main artillery. Under the bombardment of that fire, body of Devourer by the shell direct bang, was exploded is split up. 那残存的19辆坦克也开始用主炮向着那些吞噬者进行炮击。在那炮火的轰击之下,一头吞噬者被炮弹直接轰中身体,炸得四分五裂。 However these Devourer traveling speed are extremely rapid, that 19 tank round bombing only kill two Devourer other Devourer to turn toward here to overrun merely at once. 不过那些吞噬者的移动速度太过迅速,那19辆坦克一轮炮击仅仅只干掉了两头吞噬者其他的吞噬者旋即向着这边冲了过去。 Almost was the flash has Twenty first 70 levels of Devourer to pass through the blockade line, flushed toward these tanks. 几乎是一瞬间就有二十头70级吞噬者穿过了封锁线,向着那些坦克冲了过来。 So long as has destroyed 19 tanks of that surviving, the Yue Zhong this Armor army has only abandoned the larger part. 只要摧毁了那残存的19辆坦克,岳重的这只装甲部队就废了一大半。 Yue Zhong looks that turns toward in the Twenty Devourer eye that here clashes severe glow to dodge loud shouting to clear the way: „Damn! Ying Kaishan , helping my!!” 岳重看着那向着这边冲来的二十头吞噬者眼中厉芒一闪大声的喝道:“该死！鹰开山,来帮我一把！！” After Ying Kaishan follows Yue Zhong, experienced the small town beast tide that difficult to fight the Enhancers rank also to promote 49 levels, and fight was experienced, had greatly strengthened battle strength. 鹰开山追随岳重之后经历了小镇兽潮那艰苦一战强化等级也晋升到了49级,并且战斗经验丰富,拥有极强的战斗力。 Heard the order of Yue Zhong, Ying Kaishan arrived at his side instantaneously, looks Twenty Devourer that was flushing, has issued the order toward the subordinate: „Releases Gravity Manipulation fully!! Spatial air lock and other restrictive Skill!” 听到了岳重的命令,鹰开山瞬间来到了他的身边,望着那冲过来的二十头吞噬者,向着部下下达了命令:“全力释放重力操纵！！空气锁等限制性技能！” In Expert group that Ying Kaishan commands, that had restrictive Skill Expert one to release their ability toward that Twenty Devourer . 鹰开山统领的高手团之中,那一个个拥有限制性技能的强者一下向着那二十头吞噬者释放出了他们的能力。 Gravity shackles, the spatial air locks, deceleration and other restrictive Skill take away as many things as possible toward that Twenty Devourer . 一道道重力枷锁、空气锁、减速等诸多限制性技能向着那二十头吞噬者席卷而去。 That Twenty Devourer that can compare favorably with the Second-Rank Lightning ghosts and demons speed one to drop much under that restrictive Skill bombardment..... 在那一个个限制性技能轰击之下那二十头吞噬者那可以媲美二阶闪电的鬼魅速度一下下降了不少。…。 Yue Zhong deeply inspires, grasps that Devil Flame big sword one to overrun toward that Twenty first 70 levels of Devourer . 岳重深吸一口气,手持那魔炎大剑一下向着那二十头70级吞噬者冲了过去。 Several flash, Yue Zhong one appeared in a tank phonetic component, in the hand the sword of blade edge length four meters huge Devil Flame just jumped up Devourer above tank to cut directly toward one, simultaneously the flash also started Gravity Manipulation Skill, held a time of gravity in addition in the body of that Devourer 几个闪动之间,岳重一下出现在了一辆坦克声旁,手中刃长四米的巨大魔炎之剑向着一头刚刚跳上一辆坦克之上的吞噬者直接斩去,同时一瞬之间也发动了重力操纵技能,将一倍重力加持在了那头吞噬者的身 That Devourer body on two times of gravity, in addition Yue Zhong is Gravity Manipulation of release, its body one carries a heavy load reaches as high as three times of serious gravity makes its ghosts and demons speed was slower, before no longer, like that fearful, was cut two sections of faint trace black blood sputtering by a Yue Zhong sword directly, has blacked outer layer Armor of that tank. 那头吞噬者身体原本就中了两倍重力,再加上岳重是释放的重力操纵,它的身体一下负重高达三倍沉重的重力让它那鬼魅般的速度慢了许多,不复之前那般可怕,直接被岳重一剑斩成了两截丝丝黑血溅射而出,染黑了那辆坦克的外层装甲。 Originally by the Yue Zhong strength , to kill Devourer also to want Fei Xie the hands and feet, is cooperating with various person, he can a that simple sword cut to kill Devourer . 原本以岳重的实力要想干掉一头吞噬者还要费些手脚,可是在诸人的配合之下,他才能够那么简单的一剑斩杀一头吞噬者。 Yue Zhong just a sword cut to kill that Devourer , six first 70 levels of Devourer turned toward him to throw instantaneously. 岳重刚刚一剑斩杀了那头吞噬者,六头70级的吞噬者瞬间向着他扑了过来。 Although these Devourer do not have the eye, actually evolved the extremely keen sense of smell and sense of hearing, and had extremely fearful Danger Perception ability. They can feel that present human race has the enormous threat to them, therefore then in abundance jumped. 那些吞噬者虽然没有眼睛,却进化出了极为灵敏的嗅觉和听觉,并且拥有极为可怕的危险感知能力。它们能够感觉到眼前的这个人类对它们拥有极大的威胁,因此这才纷纷的跳跃了过来。 In Yue Zhong soon will be surrounded by that six Devourer , the distant place Ying Kaishan big hand wields, innumerable [say / way] incisive Icicle(s) are similar to the shell turns toward that six first 70 levels of Devourer bombardments to go generally. 就在岳重即将被那六头吞噬者包围之际,远方鹰开山大手一挥,无数道尖锐的冰锥如同炮弹一般向着那六头70级的吞噬者轰击而去。 That six first 70 levels of Devourer does not dodge does not evade, whatever these incisive Icicle(s) bang have crushed above their bodies, these incisive Icicle(s) are also not enough to tear them to resist the scales of 25 millimeters machinegun. 那六头70级的吞噬者不闪不避任凭那些尖锐的冰锥轰在了它们的身体之上粉碎开来,那些尖锐的冰锥还不足以撕裂它们能够抵挡25毫米机关炮的鳞甲。 Ying Kaishan both eyes concentrate, continue to start ability, a these incisive Icicle(s) smashing, the maternal uncle changes to a layer upon layer light glazed frost to attach above the bodies of these Devourer at once, increases their body weights. 鹰开山双眼一凝,继续发动着能力,那些尖锐的冰锥一粉碎,旋即舅化作一层层薄薄的薄冰依附在了那些吞噬者的身体之上,增添它们的身体重量。 Incisive bone spears from explode at the same time shoots, but explodes toward that six first 70 levels of Devourer shoots to go. 一道道尖锐的骨刺从一边爆射而出向着那六头70级的吞噬者爆射而去。 Facing that incisive bone spears, that six first 70 levels of Devourer wields the claw, these bone spears unceasing cutting off. 面对那尖锐的骨刺,那六头70级的吞噬者挥动爪子,将那些骨刺不断的斩断。 While this opportunity, the Yue Zhong personal appearance dodges, presented in first 70 levels of Devourer , started Gravity Manipulation Skill to fall on the body of that Devourer then a sword directly cuts two sections that Devourer . 趁着这个机会,岳重身形一闪,出现在了一头70级吞噬者的身后,发动重力操纵技能落在那头吞噬者的身上然后一剑直接将那头吞噬者斩成了两截。 After a sword cuts kills that Devourer , the Yue Zhong left hand flame dodges, a Devil Flame lance baseless and presently, then changes to stream of light to prick in the head of another Devourer to blast open directly. 一剑斩杀那头吞噬者之后,岳重左手火光一闪,一根魔炎长矛凭空而现,然后化作一道流光直接刺入另外一头吞噬者的头颅之中炸裂开来。 Almost was at the same time, the speed surmounts the form of speed of sound to leap together from Corpse Sea, bit above a head of Devourer , bit to explode the head of that Devourer , was Third-Rank Lightning. 几乎是在同一时间,一道速度超越了音速的身影从尸海之中跃出,一口咬在一头吞噬者的头颅之上,将那头吞噬者的脑袋咬爆,正是三阶闪电。 Third-Rank Lightning comes surmounts speed unceasing throwing of speed of sound to strike these Devourer by that at once, a leader thought head unceasing tumbling of somewhat thorny 70 levels of Devourer including Yue Zhong to the ground. 三阶闪电一现身旋即以那超越音速的速度不断的扑击着那些吞噬者,一头头连岳重都觉得有些棘手的70级吞噬者的脑袋不断的滚落到了地上。 Distant place Ying Kaishan sees this, in the heart shakes: „Quite fierce!!” 远方鹰开山看到这一幕,心中一震:“好厉害！！” When by Third-Rank Lightning full speed erupts that supersonic speed, only needs one to put in an appearance Ying Kaishan will directly then be killed. 以三阶闪电全速爆发之时那超音速的速度,只需要一个照面・鹰开山便会被直接干掉。 In Gui Ning City, besides these Agility Evolver, other type Evolver, only if ready very early in the morning, otherwise is also one puts in an appearance must be killed by Third-Rank Lightning. 在贵宁市之中,除了那些敏捷进化者之外,其他类型的进化者除非一早就做好准备,否则也是一个照面就要被三阶闪电杀死。 Short less than ten seconds 14 of that surviving receive all sorts of restrictive Skill attacks Devourer to be killed by the Lightning direct second at once. 短短不到十秒钟・那残存的14头受到种种限制性技能攻击的吞噬者旋即被闪电直接秒杀。 That 14 Devourer die, the entire corpse group then again does not have anything to resist the branch of the services of that steel and iron mighty current advancement..... 那14头吞噬者一死,整个尸群便再也没有什么能够抵挡那钢铁洪流推进的兵种。…。 Massive zombies directly the steel and iron mighty current crush headed by 19 tank have become by that the meat sauce. 大量的丧尸直接被那以19辆坦克为首的钢铁洪流碾压成了肉酱。 That huge corpse group was compelled by a that steel and iron mighty current street roller unexpectedly has drawn back 15 kilometers far. 那庞大的尸群竟是被那钢铁洪流一路碾压逼退了15公里远。 Compels after that huge corpse group has drawn back 15 li (0.5km), that steel and iron mighty current army rapidly withdraws, returned in Gui Ning City. 将那庞大尸群逼退了15里之后,那只钢铁洪流部队则是迅速后撤,退回了贵宁市之中。 After day of struggle, the fuel oils and ammunition of that steel and iron mighty current need to supplement that inside pilot also needs to rest. 经过一天的苦战之后,那只钢铁洪流的油料、弹药都需要补充,里面的驾驶员也需要休息。 Simultaneously the Ying Kaishan unit experienced day of struggle, needs to rest. 同时鹰开山部经历了一天的苦战,也需要休息一下。 That three million zombies are not a small number Yue Zhong has not planned for day to be able it wiping out. He when sets out the trump card crush zombies regiment near evening, wants to strive for the respite for own army the time. After all the night fighting was too disadvantageous regarding human race. 那三百万丧尸不是一个小数目・岳重也没有打算一天就能够将之全歼。他在将近晚上的时候出动王牌碾压丧尸军团,也只是想为自己的部队争取一下喘息的时间。毕竟夜战对于人类来说太不利了。 15 kilometers distance also takes several hours to walk regarding slow-acting Common zombies. Common zombies running speed is slow, on average each hour about 1 kilometer. But they are also and principal force of human race fight. If no Common zombies disturbance, the zombies regiment that Yue Zhong already that attacked killed torn to pieces. Plaque 15公里的路程对于行动迟缓的普通丧尸来说也需要十几个小时才能够走完。普通丧尸行走速度缓慢,平均每小时只有1公里左右。可是它们也是和人类战斗的主力部队。若是没有普通丧尸干扰,岳重早就那进攻过来的丧尸军团杀得支离破碎了。匾 The curtain of night arrives finally slowly, the innumerable steaming hot suppers were delivered to above the front, the supper is the cooked rice of bulk Second-Rank Mutant Beast meat and open-ended supply. Various non-staple food products that the innumerable rear area Gui Ning City commerce produce in a hurry. 夜幕终于缓缓降临,无数热气腾腾的晚餐被送到了前线之上,晚餐乃是大块的二阶变异兽肉和敞开供应的白米饭。还有无数后方贵宁市商贩赶制出来的各种副食品。 Entire Gui Ning City all people know that this war is important, once is defeated, they will be destitute and homeless once more order that establishes newly completely will also collapse. 整个贵宁市所有人都知道这一战事关重大,一旦失败,他们将会再次流离失所・新建立起来的秩序也会完全崩溃。 Many people had experienced in disorder that period of dark time, that is the humane collapse, eats each other's children, for a bread can take away human life fearful time. In order to protect their homelands, all people spontaneously moved, the young adults continually are constructing various fortification in Gui Ning City, the woman and child are responsible for making various types of steaming hot food to eat for front Warrior. Battles to have an advantage in own within the boundaries, that is Warrior does not need to eat the canned food. 许多人都曾经经历过无秩序那段黑暗时间,那是人性崩坏,易子而食・为了一块面包能够夺去一条人命可怕时间。为了守护他们的家园,所有人都自发的动了起来,青壮年在贵宁市之中不断的建设着各种防御工事,女人和小孩则是负责制作各种热气腾腾的食品供前线的战士食用。在自己境内作战有一个好处,那就是战士们不用吃罐头。 Zheng Minghe takes a material to say toward the Yue Zhong report: „Today a day, died in battle three hundred Twenty seven people, consumes the bullet 900,000 rounds, the shell 600 rounds...... the bullet that we keep in stock at present, even/including Fuzhuang the bullet calculates together. Only remaining 1.3 million rounds. Rocket projectile. Shell 500 rounds of 122 millimeters caliber.” 郑明和拿着一份资料向着岳重汇报道:“今天一天,战死三百二十七人,消耗子弹900000发,炮弹600发……我们目前库存的子弹,连复装子弹一起计算在内。只剩下1300000发。火箭弹・・・・・・。122毫米口径的炮弹500发。” Yue Zhong is listening to a report face of Zheng Minghe dignified today he exhausts fully, the card in a hand completely attacks the zombies quantity of killing to estimate that has surpassed 700,000. His ammunition consumption also is quite but serious. 岳重听着郑明和的汇报一脸的凝重・今天他用尽全力,底牌尽出击杀的丧尸数量估计超过了700000。可是他的弹药消耗也极为严重。 1.3 million rounds of bullet spear|gun of surviving, most can kill 1.3 million zombies. However that is impossible matter. 残存的1300000发子弹就算一枪一个,也最多能够干掉1300000头丧尸。不过那是不可能的事情。 The rear service is the life of modern firepower. If there is sufficient ammunition, several 40 rocket launching trolley continuous launch rocket launchers sufficiently have eliminated massive zombies. 后勤是现代火力的命脉。若是有充足的弹药,十几辆40管火箭发射车一直持续不断的发射火箭炮就足以消灭大量的丧尸。 Today can strike to kill 70 ten thousand zombies, that heavy artillery and Armor camp hunt and kill the zombies main force. That consumption 900,000 rounds of bullet true elimination zombies also only then probably 60,000. 今天能够击杀70万丧尸,那重炮和装甲营才是猎杀丧尸的主力。那消耗的900000发子弹真正消灭的丧尸也只有大概60000多头。 Yue Zhong waving made Zheng Minghe draw back, was looking at distant place brow tight wrinkle directly in heart static wants saying: „Only can have a look at that trap to succeed!” 岳重挥挥手让郑明和退了下去,直接望着远方眉头紧皱・心中静静的想道:“只能够看看那个陷阱能不能成功了！” „And other!!” Suddenly, the Yue Zhong miraculous glow dodges, suddenly has thought of anything, but that inspirational being written in water made his brow one wrinkle. “等一下！！”突然之间,岳重灵光一闪,突然想到了什么,可是那个灵感转瞬即逝让他的眉头一下皱了起来。 How regardless of Yue Zhong goes to think, the inspiration that vanishes still does not see, making him somewhat depressed. 只是无论岳重怎么去想,那消失的灵感依然不见,让他有些郁闷。 „Brother, ate meal!!” At this moment, before Mu Xiangling is similar to filled the Vitality fawn to arrive at the body of Yue Zhong, vivaciously draws his big hand to walk in the direction of dinner table..... “大哥哥,吃饭了！！”就在这时,幕香菱如同一只充满活力的小鹿蹦蹦跳跳的来到了岳重的身前拉着他的大手向着餐桌的方向走去。…。 „Um!” Yue Zhong was drawn above dinner table by Mu Xiangling, mechanical sends in that Third-Rank Mutant Beast meat own mouth. “嗯！”岳重被幕香菱拉到了餐桌之上,机械的将那三阶变异兽肉送入自己的口中。 That Third-Rank Mutant Beast meat processes after the chef, the entrance, falls into the abdomen then to change to the faint trace warm current to supplement Yue Zhong battles stamina and Spirit that today consumes. This restores the stamina best food supplement. 那三阶变异兽肉经过名厨处理,入口即化,一落入腹中便化作丝丝暖流补充着岳重今天激战消耗的体力和精神。这是恢复体力最好的滋补品。 Ning Yuxin sees asking of that worried Yue Zhong face worry: „How?” 宁雨欣看到那心事重重的岳重一脸担心的问道:“怎么了？” „Definitely was hunts and kills zombies to meet difficultly!” Mu Xiangling looked at Yue Zhong one to say directly: „Brother, these aren't zombies directs by Z Type zombies? So long as you did eliminate Z Type zombies not on the line?” “肯定是猎杀丧尸遇到困难了！”幕香菱瞧了岳重一眼直接道:“大哥哥,那些丧尸不是由z型丧尸指挥吗？你只要消灭z型丧尸不就行了？” Yue Zhong heard shakes the head saying: „ Where is so simple!! That 2 million corpse groups extend dozens li (0.5km), looks, completely is zombies. These Z Type zombies had the wisdom, where had that simply can find their positions? Moreover they always like staying in the safe place. 岳重闻言摇摇头道:“哪有那么简单！！那2000000尸群延绵几十里,一眼望去,全部都是丧尸。那些z型的丧尸已经拥有了智慧,哪有那么简单能够找到他们的位置？而且它们一向喜欢呆在安全的地方。 „And other!! Safe place?” Yue Zhong talk about here sudden brain the miraculous glow dodges an idea to well up suddenly. He one excited, grasped nearby Mu Xiangling to kiss above her elegant face continually two: „Too thank you!! Small Xiangling!! Ha Ha!!” “等一下！！安全的地方？”岳重讲到这里突然脑中灵光一闪一个想法突然涌上心头。他一下兴奋了起来,一把抱住了旁边的幕香菱在她的俏脸之上连亲了两下:“太谢谢你了！！小香菱！！哈哈！！” Mu Xiangling one was held by Yue Zhong in bosom has kissed two continually, then one has struggled, elegant face micro cooked food red with the sound that only then periphery the person can hear called out: „Lolicon!! Abnormal, lets loose me quickly!! Does not let loose me, I must yell!!” nang 幕香菱一被岳重抱在怀中连亲了两下,便一下挣扎了起来,俏脸微饔红用只有周围人能够听到的声音叫道:“萝莉控！！变态,快放开我！！再不放开我,我就要大叫了！！”曩 „Ha Ha!!” Yue Zhong smiles, mood very happy has put down Mu Xiangling. “哈哈！！”岳重一笑,心情十分舒畅的放下了幕香菱。 „Leader!! zombies started the night assault!” In Yue Zhong just put down Mu Xiangling, a pass on message officer one arrived here anxious incomparable saying. “首领！！丧尸发动了夜袭！”就在岳重刚刚放下幕香菱之时,一名传讯官一下来到了这里焦急无比的说道。 „What? My this goes!” The Yue Zhong complexion changes, put down Mu Xiangling to grasp a bulk Third-Rank Mutant Beast meat not to flush away toward outside toward a mouth with the hand any vivid stride directly. “什么？我这就去！”岳重脸色一变,放下了幕香菱直接用手抓了一大块三阶变异兽肉往嘴里一塞没有任何形象的大步向着外面冲去。 Ning Yuxin and Xin Jiarou two females look at each other one, finished eating the barbecue in their tray in a hurry, this followed. 宁雨欣、辛佳柔两女对视一眼,匆匆的吃完了她们盘子之中的烤肉,这才跟了过去。 Yue Zhong arrived at the forefront quickly, sees only under that dark shield, 10,000 sz are similar to the ghosts and demons turns toward Yue Zhong here position to clash generally. 岳重很快来到了最前线,只见在那黑暗的掩护之下,10000头sz如同鬼魅一般向着岳重这边的阵地冲过来。 That huge corpse group was driven away several kilometers by the Yue Zhong Armor army, these Common zombies changes are unable to come slowly that quickly. Also only then evolution zombies can that quickly on return here. 那庞大的尸群被岳重的装甲部队驱赶出了十几公里,那些普通丧尸异动缓慢根本无法来得那么快。也只有进化丧尸能够那么快就回到这边。
