Under One Person: Since I am alone, I can dominate the world

Traveling through to Under One Person and becoming Zhang Zhiwei's junior fellow, Zhang Taichu awakened the Universal Power Immortal Path System at the beginning. As long as he recruited disciples vigorously, he could gain feedback on his cultivation.
However, due to his violent personality, Zhang Taichu had no intention of accepting any disciples. He relied solely on his natural talent to cultivate to the level of a human immortal. He went down the mountain in a rage after learning that Zhang Huaiyi was forced to defect and Tian Jinzhong was deposed.
Zhang Taichu: "Why do I care about what people think when I have unrivaled strength? I just want to avenge Old Tian! Why can the big-eared thief only return to Longhu Mountain before Master can protect him? Wherever the Heavenly Master is, this place should be Longhu Mountain!"
So, Zhang Taichu, with his sword, killed his way through the world of aliens, and even challenged all the aliens in the world to a battle in Guanshan Gorge. He personally wiped out all the major families and ended the Jiashen Rebellion!
For this reason, in order to protect him, Heavenly Master Zhang Jingqing had no choice but to let Zhang Taichu face the wall in Mount Longhu for decades to cultivate his body and mind!
It was not until the Luotian Grand Ceremony was opened and the extraordinary people in the world gathered again at Longhu Mountain that senior brother Zhang Zhiwei realized that although his killer junior brother had been facing the wall for more than 70 years, his personality had not changed at all!
