Martial Arts: Starting from Swordsman, He Starts Cheating the Master God

Yue Yuanbai accidentally traveled through time and came to the world of Swordsman and became Yue Buqun, the head of Huashan. When other people traveled through time, they either had great status or became peerless geniuses. How come he turned out to be a villain and a hypocrite? Thinking of the ending of Yue Buqun in Lenovo's original work, Yue Yuanbai was confused at the time. Fortunately, the system was activated at this time. But just when Yue Yuanbai thought that he would use the system to embark on the path of unifying the world and dominating the martial arts world, he discovered that what he had crossed might not just be as simple as Swordsman. The newly recruited disciple actually hid in the latrine and smoked Huazi. Are there Huazi in this world? Didn't it mean that this was the Huashan Swordsmanship? What's going on with their modern weapons?
