Douba's Dual System

As a traveler, being able to get a system is a great opportunity.On the other hand, Chen Cheng has the assistance of two systems, namely, a copy system that has the ability to copy others, and the Myriad Summoning System that can summon characters from Myriad Worlds.
When Chen Cheng was reborn in a different world and learned that the world he was in was the Izumo Empire of the Dou Qi Continent, all the stories began from there.
