After undergoing that kind of experiment, Zhou Tian naturally saw through it. Initially, he thought it was the suppression effect of the perilous situation's rules, but in reality, it was the treant's ability. As long as he got close to that treant, his ability would be suppressed, so unless he chose not to fight the treant, he had to be psychologically prepared for his strength to be suppressed if he still intended to deal with it.
At present, Zhou Tian was no exception; unless he decided to leave right away, according to his plan at the time, unless that treant 'died', Zhou Tian would have to be ready to lose his abilities if he got close to it or even tried to enter its body like those deities did.
