Emperor's Legend 2020

On the other side of the dimension, there is an extremely bright and vast world. This world is very similar to the ancient human world on Earth. An unknown Chinese soul from Earth entered that world through a series of coincidences and was reincarnated into the emperor's home. The only unfortunate thing is that he seemed to have arrived too late and failed to become the prince. However, the seventh prince of the Tianyue Empire seems to be pretty good too.
