Gu Zhen Ren
For those who don't get why everyone thinks strength path is lame.The reasons are:- It is 1 million years old so a lot of recipes and their ingredients are extinct so there are almost no rank 5 or rank 6 recipes then how can one cultivate? It lacks long range methods. Also I have read all 2200 chaps and there are only 3 strength path immortals that I could find.
