Will the blood monkeys let them pass?
It's clear from thinking that this kind of thing would not happen. After all, in the eyes of those blood monkeys, the deities are hard-won food delivered right to them. Given their tribal situation at the time, if they wanted to restore their clan's vitality, enough food would certainly be necessary. Although there are some living beings in the Gorge that can provide them with fresh blood, in terms of energy and effect, the blood of those living beings cannot compare to Divine Blood.
Therefore, no matter how they came into conflict with those deities, and regardless of whether this matter was caused by Zhou Tian, given the situation at the time, once those deities stepped into the Gorge, they should not expect to have an opportunity to leave alive.
As a result, when those deities began to retreat, the blood monkeys immediately started their blockade.
