Chu Yunfan thought, 'These Bloodmane apes are indeed vengeful. They must've realized that one of their members hadn't returned, so they chose to seek revenge after the storm!'
He never underestimated the apes because the apes could rival human intelligence. The apes had intelligence levels equal to that of an elderly human. Intelligence was God's great gift to humankind, after all.
Six Bloodmane Apes appeared in Chu Yunfan and the others' camp simultaneously. Chu Yunfan swiftly stopped two apes, but that was all Chu Yunfan could handle so far. He could have used all his firepower if not for his weighted suit. He could already defeat an Energy Refinement stage expert, let alone six apes.
Nonetheless, Chu Yunfan had exerted all his strength to deal with the first two apes. The pressure from his weighted suit's doubling gravity function was more significant than he had imagined.
