With Grand Tutor's proud personality, he would rather risk getting possessed than cultivate using a human furnace to achieve Yin and Yang harmony.
The first dual cultivation with Lu Bei was because his body couldn't resist; the lure of Taiyin Kill Skill was too strong for Tai Yang Reverse Tao, giving Lu Bei an easy victory.
Even after achieving harmony, she did not give up the possibility of achieving it alone. If it weren't for the fact that Innate Yiqi and longevity were inextricably linked, Lu Bei wouldn't continually retreat into her meditation room.
Therefore, even having tasted the sweetness of using a furnace, the Grand Tutor would not cultivate using more furnaces. He would instead treat the present one well and do everything possible to perfect it.
Knowing the situation, Lu Bei boldly asked for the Grand Tutor's physique-enhancing peaches.
