I Pretended to Be Demon Lord Bai Yueguang

I traveled through time, and my boss sent me here with the task of finding out the truth behind the death of the previous time traveler, Lan Siyu. So I was disguised as Lan Siyu and went undercover to the side of the demon king who kills people if he disagrees with me. The Demon Lord recognized at a glance that I was not her, because Lan Siyu was his Bai Yueguang. Later, after my investigation, I learned that the Demon King wanted to destroy the world, and my boss asked me to stop him. I weighed my body and bones: Why? Relying on face? Boss: Smile more, your luck will never be too bad Me: ... I can go to your grandma's house! … This world is not destroyed after all Because she loves this world, and he loves her deeply. … Short story, about 30,000 to 40,000 words Motto: Love is irreplaceable
