This took the Mystical Whale by surprise, as it did not imagine that Shen Lian could help it with its injury. The divine power Shen Lian exhibited while not as great as his previous owner, Mister Sea, it was still extremely powerful. He would not just be making empty promises.
It also could not imagine that twenty years ago, Shen Lian was just a small cultivator which could be swallowed by it.
Shen Lian waited until the Mystical Whale came to a decision. Other than him, only people of the rank of immortal Zhenren could help with the injury of the Mystical Whale.
The Qi of devilry surrounding the injury was extremely intense. If an average cultivator came in contact with it, his body and mind would have been frozen. The coldness could also destroy the spirit and the mind.
