Back then, when sending people to capture Gao Shengnan, although one of the objectives was to lure Bai Xiaofan over and avenge Liu Mu, there was actually another motive!
That was told to him by Master Zi Qing after he came back, that Gao Shengnan is an innate spiritual body, and if she were to cultivate, her speed would be extremely astonishing!
Of course, he didn't bring Gao Shengnan back to teach her how to cultivate, but rather to use a secret technique to transfer Gao Shengnan's physique onto himself.
In that way, he might have the chance to break through the age constraints and advance to a higher realm.
Although the lifespan of cultivators is often longer than that of ordinary people, there is always a limit.
He was close to exhausting the lifespan limit that a beginner tribulation transcender could reach!
