Li Yu has a special constitution: his "sense of presence" will continue to disappear and be forgotten. When completely forgotten, he will "conceptually die". To this end, he must constantly "engrave" his own existence - create techniques that will be passed down through the ages, establish an immortal dynasty, and become a legend sung by epics. He is the most helpless hero in history, and he does all his feats just to not be forgotten by the world. When he was finally on the verge of being completely forgotten, looking back in the void, he found that the skills, dynasties, and legends he left behind... They "remembered" him and gathered into a majestic will to bring him back to reality. From then on, he himself became the oldest legend.
