In The Heaven Sword and Dragon Sabre, which main character had mastered the Nine Yang Skill?

Chu Yang, the Ninth Master of the Nine Tribulations Sword, sacrificed almost everything he had for the sake of improving his martial arts, including the love of his life. After spending three years locating the fifth fragment of the Nine Tribulations Sword, he was ambushed by all sides at that very place. Mortally injured with no means of escape, Chu Yang executed a sacrificial technique by plunging the Nine Tribulations Sword into his very own heart. “With the blood of my heart, ten thousand tribulations will collapse!” After witnessing the death of all his ambushers, Chu Yang’s vision began to darken. At a distance, moments before his death, he saw the mastermind who had plotted his downfall — Mo Tian Ji. With that, his eyes finally closed. However, with a start, Chu Yang once again awoke to find that he had returned to when he was sixteen years of age! Furthermore, the Sword Spirit of the Nine Tribulations Sword now resided within his Dantian, the energy center of his body! From that very moment, Chu Yang would then begin to right all of his past regrets, and carve his very own legend by fulfilling his destiny as the final Master of the Nine Tribulations Sword, and defeating the Heavenly Devils beyond the realm of the Nine Heavens Continent.

With five strikes of his axe, Emperor Yu split the mountains and unified everyone beneath the heavens. He partitioned the land into nine prefectures and erected the nine cauldrons. After Emperor Yu's death, incessant disputes arose within the Land of the Nine Prefectures. One thousand years later, a once-in-a-generation genius—the Heavenly Emperor of Qin Mountains—emerged from out of nowhere. With a strike of his palm, he was able to stop the motion of the 100-meter wide Yan River. With his peerless martial prowess, the Heavenly Emperor of Qin Mountains was ultimately able to unite the land beneath the heavens. However, when he died, chaos once again shrouded the Land of the Nine Prefectures. Several thousand years passed by, and still, no one was able to consolidate the nation. Then the Grandmaster of the Xing Yi Martial Art—Teng Qingshan—arrived here unexpectedly from the modern world.

A decision can destroy the sun, moon and stars. A finger can kill the Heavenly Overlord. While chatting, the Heaven and ten worlds can be annihilated. A poor little kid walks out from a remote mountain area while holding the Nine Dragons and the Incredible Cauldron. With a control over the time and space eternally, he embarks on the Path to God where he defies the odds of the boundless universe gaudily by fighting against royalty and clashing with the legendary generation.

Bell Cranel was rejected by every familia he tried to join until he met Hestia. In a few, he was rejected quite violently. And in one particular instance, he was thrown out and bashed his head against a wall. Well, that's apparently where I come in. Not sure how and why I'm here. Not even sure who 'I' really am at this point since Bell's memories are definitely clearer than 'mine'... But I guess we're doing this. Hopefully I've got some useful cheats. Maybe?
