听到对讲机里传出来的对话，秦子岳脸色咻然一变，看向对讲机的眼眶，更是猛地一缩。
这个男人的第一句话，让他汗毛直立！
他的确在这边杀人！
可对方是如何知道的？
难道，这男人是对面那栋楼里的幸存者？
不！
如果是对面那栋楼的幸存者，在这么猛烈的攻击之下，不可能还能做到如此淡定，语气里轻描淡写，甚至还扬言要去救人。
肯定不是对面的人。
那他是谁？
秦子岳眉头微凝，拿起对讲机按了一下通话键，然后又松开。
忍住。
看对方究竟打什么主意！
“大哥，大哥你真能来救我们吗？有什么条件你说！”对讲机里，女人的声音明显激动起来。
没隔一会儿，男人的声音再度响起，显得很淡定，“你先说说位置，条件再谈，能不能去还不一定呢。”
正好这时，直升机降落在楼顶。
祺盛玩具厂。
天台铁皮房后面。
看着对面大楼上，直升机徐徐升起，然后飞向那座钢铁堡垒，孙大海眸子里迸射出一道浓郁精光。
果然是那座钢铁堡垒里面的人！
他一直在猜测，究竟是谁，有这么大仇恨，不惜搬出狙击手，也要将自己这群人赶尽杀绝！
猜测可能是堡垒里面的，但不太确定。
可看到直升机之后，他马上便明白了原委。
孙大海脸色阴沉如水，眼中迸发着愤怒的火焰。
在楼下汽车油箱被打爆，爆炸声接连响起的瞬间，他便悄然从门内爬出来，借着走廊过道边的水泥护栏的视线阻挡，直接趴在地上爬行，然后转向楼梯，上了天台躲避。
好不容易收拢招揽的幸存者和物资，一夜之间几乎全都没了。
货柜车要么爆炸，要么被火海吞噬，就算有还能开的，可也都被丧尸侵占，他一个人根本没办法夺回来。
而刘启胜他们，要么被堡垒里面的狙击手射杀，要么此刻也都已经葬身丧尸潮中，成了丧尸的早餐。
几近团灭！
“晦气！”
“总有一天，我一定要住进里面！”
深深看了一眼钢铁堡垒，孙大海眉宇阴沉，而后直接跳下楼。
在这栋宿舍楼与工厂后围墙的铁栏杆上，还系着两道绳索。请求出错，状态码:0内容:请求出错，状态码:520内容:<!DOCTYPE html>
