The Warring States Period, Shuiyuan's Corps System

Shuiyuan, the useless protagonist of this book, traveled to a different world because of his identity as the holder of the source fragment, but this fragment looks like a plug-in but has almost no effect. With a system wizard and a system that has almost no sense of existence. Conquer the world by summoning creatures, travel through different dungeons and stack buffs to increase combat power, and become the strongest force in the main world. The first stop in the dungeon, Benzi's Warring States Period, is to kill Xiaobenzi's ancestors first. There will probably be Three Kingdoms in the future, and I will try the original copy.
