My Son Is All Worthy of the Emperor

(Cultivation to immortality, time travel, various scenes of recognizing one's father's name, non-straightforward writing) I have a friend. In terms of appearance, cultivation, family background, and talent, in the entire world of immortality, he can only be regarded as an average person, mediocre and hardly noticeable. I don't know why, but the children he and the woman gave birth to were all the property of the Great Emperor. And this kind of weirdness made him unexpectedly become a hot commodity in the world of cultivating immortals. Countless sects, great powers, kings, and aristocratic families just wanted to leave a son and a half for each of their forces, so that they could soar to the sky. My friend was very confused, so he used various treasures given to him by the children to travel through the multiverse, hoping to become Xu Xiake in the world of immortality. But things often go against expectations, and people who are looking forward to it always come one after another...
