Although Zhou Tian was mentally prepared to let those blood monkeys absorb some divine blood, ultimately, letting someone draw blood is never a good thing. So, at that moment, when carrying out the plan, Zhou Tian was indeed quite concerned about the actions of those blood monkeys.
And because Zhou Tian was always paying attention to the movements of those blood monkeys, he unexpectedly noticed some changes in his body at that time.
In the past, Zhou Tian could only become aware of the existence of those blood monkeys by monitoring changes in his body weight or other factors. Such methods certainly had their weaknesses because those blood monkeys would be careful not to let their actions reveal any hint of their presence. Given the situation then, if there was any slight slip in attention, even a deity with Zhou Tian's strength might overlook those subtle changes.
