With this thought in mind, Qin Qi immediately sat cross-legged on the bed.
Once again, he launched an assault on cultivating True Qi of the Tian Gang.
Following the previous cultivation method, he operated the mental method of the Tian Gang True Qi within his body, and began slowly mobilizing the Yang energy within himself, thoroughly cleansing the True Qi in his Dantian.
Indeed, the mysterious woman's judgment was correct.
Last time when he cultivated Tian Gang True Qi, using Yang energy to cleanse the True Qi within himself, only when the process was halfway through, he obviously felt somewhat powerless; the Yang energy couldn't keep up.
But this time, the result was vastly different.
A large amount of Yang energy surged in, causing the True Qi in the Dantian to be stirred up violently.
"Hmm? My True Qi has obviously changed!" Qin Qi was astonished.
