Ling Yun was already at the foot of Yunmeng Mountain when Chen Jianwei flew back to his lair.
He wasn't escaping. There was no need for it since Cao Shanshan was back in his arms. Ling Yun's preparations were sufficient for this battle.
Ling Yun dashed out so fast only because he wanted Cao Shanshan to get into the car quickly so that she wouldn't be drenched to the bone.
The rain was too heavy, and everything was veiled in its curtain. The surface of the mountain seemed akin to a fast stream or river, with flash flooding everywhere.
The torrential rain definitely affected Chen Jianwei's vision. He might be at the pinnacle of Xiantian Realm Level Six, but he couldn't see clearly through the heavy downpour.
Chen Jianwei was almost flying along the treetops, but the Yunmeng Mountain was too big, and there were small waterfalls everywhere. The rain blocked his line of sight and affected his hearing, which effectively infuriated him.
