Qi Yunjue did not just seek revenge, he wanted to erase the evil of the Dark Empire forever.
With this in mind, he fixed his fervent gaze on the Underground Emperor.
"Underground Emperor, Yan Ling has saved you time and time again because she knows you're not a bad person! I can help you obtain the Dark Empire, but in turn, you must promise me that once you have the Dark Empire, you will stop any research into Superpower Users. Otherwise, I will take back from you a hundred, no, a thousand times over, what I give you!"
The Underground Emperor hesitated for a moment upon hearing this but promptly agreed.
To be honest, after witnessing the might of Superpower Users, he was certainly intrigued.
But he was not naive like Linxi, arrogantly thinking he could control such individuals.
The more power one possesses, the more dangerous they are.
A moment's recklessness could lead to self-immolation!
He wanted to live a few more years, he wasn't suicidal!
