Liu Yu was reborn half an hour before the end of the world. The world was shrouded in heavy fog, all communication equipment and electronic equipment were damaged, and all thermal weapons were quickly corroded and unable to be used.
But only Liu Yu's ultimate system can exchange for thermal weapons that can be used without being affected.
Liu Yu discovered that the system can be exchanged for various cold weapons and hot weapons, as well as science fiction weapons (need to be unlocked)
It can even summon many ancient arms. With this ultimate system, others are still struggling to survive.
Liu Yu, however, had already begun to lead the army to attack the city and plunder the territory.
