进入游戏四周正方形走动击杀边沿僵尸，只升级武器，时间到了3分钟左右就可以升级到火箭筒。

Enter the square around the game and walk around to kill the edge zombies, only upgrade the weapon, and you can upgrade to the bazooka after about 3 minutes.



获得火箭筒后，你就会发现僵尸都聚集到一堆，这个时候你只需要走到僵尸群中，就会一发炮弹击飞十几个僵尸。

After you get the bazooka, you will find that the zombies are gathered in a pile.
At this time, you only need to walk into the group of zombies, and a dozen or so zombies will be knocked into the air with one shell.

然后你就会获得提示。
