There was no time to think further.
Xu Wendong immediately controlled the True Qi within his Dantian to flow slowly, and then gently pushed it toward that invisible barrier.
Once!
Twice!
Five times!
Nine times!
And at the tenth time, the previously gentle True Qi suddenly turned violent, like a raging sea, crashing fiercely into that invisible barrier.
At the same time.
Xu Wendong suddenly opened his eyes wide, the swelling sensation in his Dantian vanished instantly, and he successfully stepped into the Ninth Layer of the Yin-Cultivating Realm.
"It really was just as I thought!"
"Nine soft, one hard can bring a woman an overwhelming pleasure."
"And using nine gentle, one fierce during the breakthrough can easily break the bottleneck."
"I am really damn clever."
Xu Wendong was in an excellent mood.
He didn't know why using the method of nine gentle, one fierce could lead to a breakthrough, but it felt like catching someone off guard.
