Li Yu has a peculiar constitution: his “presence” keeps fading, and people forget him. Once he is completely forgotten, he will suffer “conceptual death.” To prevent this, he must continually “engrave” his existence into the world: create cultivation techniques that endure for ages, establish an immortal dynasty, and become a legend sung of in epic ballads. He is the most unwilling hero in history, performing every great deed simply so the world won’t forget him. When he finally teeters on the brink of being forgotten for good and looks back from the void, he discovers that the cultivation techniques, dynasty, and legends he left behind have “remembered” him. Their immense power of faith gathers and pulls him back into reality. From then on, he himself becomes the oldest legend of all.
