Based on the abilities of those blood monkeys, once they decided not to engage in a hard fight with Zhou Tian, they could simply turn around and disappear from his line of sight. Witnessing firsthand how those blood monkeys vanished, Zhou Tian still dared not make any careless actions at that time.
Considering the eerie abilities of those blood monkeys, even though his strength had improved, Zhou Tian needed to remain vigilant at all times, because, without being able to detect the hidden actions of those blood monkeys, a few might leap out from the surroundings and attack him.
While the abilities of those blood monkeys might not be lethal to Zhou Tian, they would surely make him feel 'disgusted'. Regardless, Zhou Tian couldn't afford to be careless about their capabilities at any time. That was why he had to stay guarded against those blood monkeys, regardless of whether his strength had improved.
