Hey, I have two novels here that are similar to the critical noble deeds you mentioned. The first was The Uncrowned King. It was about a young man who traveled to the ancient world and used his wisdom and strength to become the King of Undying. The other book was "It's Just a Taoist". The protagonist also traveled to ancient time and space, possessed the abilities of immortals, and grew into a Taoist master. He experienced many exciting and bizarre immortal cultivation stories. I hope you like my recommendation, Mwah ~😗
