In fact, the first ghost that He Tianxiong had managed to control was not this thing stepping on his shoulders but the thing that was gradually eroding his flesh all over his body. Back then, he watched as his body decayed bit by bit each day, while something not his own kept growing back. The days of being tormented yet unable to die were the nightmare of his life.
However, this curse-like affliction on his body was not entirely a bad thing.
He Tianxiong discovered a very bizarre situation: he could no longer die.
He jumped off a building, his head cracked open, and he was even sent to the crematorium. Yet, he woke up again at night. His cracked head miraculously healed, but the downside was there were more decayed spots on his body.
Besides that, He Tianxiong discovered another situation.
If he encountered a ghost, the ghost definitely wouldn't attack the rotten parts of his body. Even if he was attacked, he wouldn't suffer any damage.
