I Am Yang Guo's Son, and I Take Zhang Sanfeng on a Journey Through the Heavens

He transmigrates as Yang Guo's son, and even gets a transmigration interface.

Everyone else travels the myriad worlds with a harem in tow. How come the only one by my side is an old Taoist?

…

…

A hundred years later.

“Old Zhang, if you can't keep up, come with me. Aren't you bored after being invincible for so many years?”

“You mean the myriad worlds? Maybe I could even run into Miss Guo again?”

“Damn it, Old Zhang, you're over a hundred and still hoping to become my uncle-in-law? Want me to beat some sense into you?”

“Wait, a whole bunch of enemies just showed up. They look pretty strong.”

“This guy's cultivation is no weaker than ours, right? Just a reminder: you beat Di Shitian so badly he coughed up all his phoenix blood.”

…

Who knows how many years later.

“Old Yang, watch out! Hongjun's cultivation is no weaker than ours!”
