La Vida Diaria del Rey Inmortal

Wang Ling is a high school student with a cool and carefree demeanor. Coming off as someone with a very low spiritual force, he actually possesses a power capable of destroying the world at a moment's notice. To mitigate the volatile force within him, his parents have resorted to using an amulet as a temporary solution. However, the amulet weakens over time and Wang Ling's emotions also accelerate its deterioration. Now with the amulet on the verge of breaking, Wang Ling and his father race against time in order to fix it.
