The Vicissitudes of Proving the Way - Part 1

I like traditional fantasy, so I wrote this book I don't want to write a cool article, and I don't want to sacrifice the original story in order to cater to the market. The protagonist, Lu Tingshan, traveled through the past in modern times. He thought that the original world was in the end of the Dharma era and could not cultivate immortality. He accidentally traveled to another small world. After many twists and turns, he thought that he could cultivate immortality, but he was not recognized by heaven because he was a person from an outside world. Then stop cultivating and break the rules with every punch.
