Why Is My Cultivation so Good and so Bad!

Xu Song was originally a monk from the Great Realm. Something went wrong when he was crossing the tribulation, and his cultivation suddenly became ineffective... The master told him that opportunities would appear by hiding in the human world, so he came to Kyushu and became a hard-working high school student. When his classmates asked him to help deliver a love letter to the class monitor, Xu Song went to send it boringly - my God, the class monitor is actually charming! When the 200-pound British strongman was transferred to the class, Xu Song gave him a lightning five-stroke whip - young man, you are a rat tail juice! When the local champion offline competition was held, Xu Song directly glanced at the screen with his consciousness - ahem, small opening does not count! When the long-legged ancient martial arts master made wild claims about accepting him as his apprentice, Xu Song originally wanted to teach her a lesson - but... The result is that you have a dead cultivation level, and you are no longer good at this time!
