When Cheng Guang woke up, he realized he had traversed to another world.He had thought his transmigrated identity would be the esteemed Princely Heir to the Duke, but he hadn’t expected an additional (pseudo-) in front of it.It wasn’t tragic, but it definitely wasn’t great either, it was just very helpless.Cheng Guang had thought that being able to be a pseudo-Princely Heir was the biggest cheat in his life, but to his surprise, he was also bound to a system.This system was even more of a scam!It seemed to have bound him three thousand years too early!It started by telling him he had advanced to the Heavenly Human Realm and instructed him to confront the Empress of Great Zhou, who was also in the Heavenly Human Realm.But he was just a small potato!However, wait a second, the Empress of Great Zhou, years later, seems to be just a pushover right now?Cheng Guang became resolute and confident again, I got this!!!
