Great Tang: I Am the Imperial Preceptor

(Myriad Worlds) + (Fantasy) + (Multiple Heroines) + (Dual Systems) + (Timeline follows this book)

He takes Old Li along, using the System to transmigrate through many worlds, recruit talent, and spread cultivation, all in preparation for venturing into the fantasy worlds later.

Modern young man Lin Feng unexpectedly transmigrates to the Tang dynasty. He had planned to make his mark in this glorious age, but fate binds him tightly to Princess Changle, and before he knows it, he becomes her consort.

Facing the imposing Li Shimin, Lin Feng is completely unafraid. Drawing on his modern knowledge, he introduces one novelty after another, from hot pot to Wuliangye, opening the eyes of this legendary emperor. Their everyday interactions are full of fun: sometimes the new inventions leave them rolling with laughter, and sometimes their clashing ideas lead to heated arguments, making for a one-of-a-kind tale of a father-in-law and son-in-law who love to drive each other crazy.
