Li Fei traveled to Uncle Jiu's world and became a coffin-born child. Fortunately, Uncle Jiu happened to be passing by and heard the cries, so he dug him out of the grave. Otherwise, he would have become the first time traveler to be suffocated to death just after crossing over. I don't know if it was because he was born in a coffin. The reason is that he will be able to practice some heretical practices faster than an upright secretary, but as the old saying goes, calligraphy is not good or bad, it depends on the person who uses it. Under the careful instruction of Uncle Jiu and his own efforts, Li Fei became a peerless heavenly master step by step.
