Dou Po's Dual System

As a time traveler, it is a great opportunity to get a system. Chen Cheng, however, has dual systems to assist him, namely the copy system, which has the ability to copy others, and the world summoning system, which can summon characters from all worlds. When Chen Cheng was reborn in a different world and learned that the world he was in was the Dou Qi Continent, the Izumo Empire, the whole story began from there. (Summoning characters is limited to Chinese comics, domestic novels, and film and television works.) (Not an invincible article.)
