Boss Sun questioned the Divine Insect in order to be prepared for any eventuality. Although this fellow was definitely an imposter, the divine power on his body couldn't be fake. There must be some connection between him and the Divine Lord.
If they reached Beast'ear Mountain and the old man sent the True Spirit Totem inside, would Boss Sun make a move? The Divine Lord was cunning and careful. Was his true body really in Beast'ear Mountain? So Boss Sun needed a side confirmation.
But after Berry suddenly had a "flash of insight," he suddenly had a bold idea: "Your Excellency..." he still disguised his voice: "We can cooperate!"
"Cooperate?" Boss Sun was noncommittal. Berry wholeheartedly trusted Robert: "I have a way to capture the Divine Lord!" With only Berry, this misadventure mission was almost impossible to complete. But if he teamed up with Robert ā in Berry's consciousness, Robert was omnipotent.
