Cheng Yaojin, the Devil Incarnate, Cuts Down Trees to Upgrade

Duke Lu Guogong of the Tang Dynasty and the demon king Cheng Yaojin obtained the tree-cutting upgrade system in their early years. I originally thought it was an ordinary historical world. Unexpectedly, one day, I saw Yuan Shoucheng on Chang'an Street. Only then did he realize that he was traveling through the world of Journey to the West. In this case, no matter whether it is heaven or Buddhism, don't try to get involved in the destiny of the human race. No matter who wants to become a demon, he must first see if I, Duke Lu of the Tang Dynasty, will Cheng Yaojin agree or not.
