Global Catastrophe: I Build the Strongest Fortress for My Sister

After re-living, Zhang Ye vowed that he would never be a good person in this life. In this life, he would not only live well in the coming apocalypse, but also live better than anyone else. Returning to his hometown again, Zhang Ye built himself a strong doomsday fortress early this time. When the doomsday came and zombies were rampant, he immediately set up a 360 mm caliber cannon, and even the caliber of the cannon aimed at the sky was as high as 188 mm. A seven-meter-thick protective layer, dozens of artillery pieces, and hundreds of heavy machine guns form a super fortress that integrates offense and defense. This will be the most feared hell for zombies and evolved beasts. Even if these doomsday creatures are evolving rapidly and becoming stronger and stronger, Zhang Ye still has the ability to make these creatures irreversible. "Zhang, you have the guts to come out for a duel." Evolver A shouted angrily at Zhang Ye. "Single fight? You want to see if you can withstand the blow of my 460mm heavy cannon." "Kill, kill that man." The Titan beast ordered to his men. "Are you sure? You have to think carefully, otherwise my thousand-millimeter cation cannon will not be polite." While talking, Zhang Ye took out a three-meter-long high-frequency ship-cutting knife from his pocket. The high-frequency wave that vibrated 300,000 times per second emitted blazing energy. "Damn it, don't you only know how to build fortresses?" Evolver B looked at the ship-cutting knife in Zhang Ye's hand and was shocked. "Who told you that I can only build fortresses?"
