Cutting Off an Aircraft Carrier with One Knife, Do You Call This a Cold Weapon?

Han Xu was assigned to an internship at the Cold Quenching Industrial Factory, a cold weapons military industrial unit that had declined. The first step is to activate the "Arsenal System" to obtain full body transformation and weapon improvement technology. A simple ring-head knife can not only stop bullets, but can even split tanks. Leader: I just want you to improve the Huanshou Sword. Why is it now more bulletproof than an armored vehicle? ! ! Old factory director: I'm just going out for a few days. How come our industrial factory that is about to close down has become famous across the country? ? ? Roommate Han Xu: We haven't seen each other for a month, why do I want to start learning from you? ! ! Han Xu: I actually just need an internship certificate, believe it or not! ! !
