I Am the Daoist Sect's Grandmaster

After unexpectedly transmigrating to a parallel world, Lin Feng is astonished to discover that martial arts have flourished here. People vaulting over rooftops and walking on water with lightness skills are practically commonplace! But then Lin Feng performs a set of tai chi, the kind even the middle-aged ladies doing square dancing in his previous life knew, and everything takes a strange turn... The sky above him suddenly displays a Taiji symbol, half black and half white! Lin Feng is dumbfounded! Can someone tell me what the heck is going on? I really don't know how to cultivate immortality! I really don't!
