Please, I Really Don't Know How to Become an Immortal

After accidentally traveling to a parallel world, Lin Feng was surprised to find that martial arts in this world were extremely prosperous. It's not too common to fly over a wall or float on water with Qinggong! But when Lin Feng did a set of Tai Chi that every square dance lady in his previous life would do, his style of painting began to change... In the sky above his head, there was a Tai Chi diagram with half black and half white! Lin Feng was dumbfounded! Who can tell me what the hell is going on? I really don't know how to cultivate immortality! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
