Di~ The appearance of the destined person has been detected, please host seize the opportunity. ... My name is Bai Yue'e, I am a great emperor on earth, invincible in the world. However, he was assassinated by the enemy. Fortunately, he was protected by heaven and reincarnated into the lower world. My enemy's cultivation is as high as the sky, and his identity must not be revealed before he regains his strength. For this reason, I joined a sect in the lower realm and planned to cultivate in hiding for hundreds of years. But I seem to be being targeted by a guy. He is very good-looking and talented. I know I must be careful but... "Yue'e, there are ten thousand top-grade spirit stones here and a hundred top-grade Yuan Gathering Pills. Use them for cultivation. If they are not enough, ask me again." He gave so much! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
