The Origin Immortal King's suggestion was actually quite good. With his background and identity, if he really recovered all his cultivation and reached the peak, or even took a step further, if Qi Ming really became the disciple of the Origin Immortal King, he would have a huge backer after ascending to the Upper World.
All of this was based on whether the Origin Immortal King was trustworthy. If the Origin Immortal King went back on his word after this, then when he recovered his full strength, wouldn't it be easy to deal with Qi Ming?
If Qi Ming chose to believe the Origin Immortal King, then he would have handed his life to the latter. He had to bet that this person was trustworthy and would not go back on his words.
He would not do this. He would definitely not hand his life to others, much less bet on whether the Origin Immortal King was trustworthy or not.
