Just like how everyone adored heroes in their childhood, a certain young man adored those powers hidden in shadows. After hiding his strength and living the mediocre life of a mob character by day while undergoing frenzied training by night, he finally reincarnates into a different world and gains ultimate power. The young man who is only playing at being a power in the shadows, his misunderstanding subordinates, and a giant organization in the shadows that gets trampled…. This is the story of a young boy who had adored powers in shadows possibly eventually reigning over the world of shadows in another world.

The entire Yunzhou knew that the Ye Family had a new step-child in the house: Ning Li, a low-born and barely literate. However, when she looked at her 17 years old self in the mirror after coming back to life, she grinned.At 17, her step-siblings had yet destroyed her looks and stolen her glory—she still had everything with her. Since she was given an opportunity to start over, she ought to take revenge on everyone who had wronged her before. It would be interesting.After Ning Li was chased out of the Ye Family, she was cherished by the most popular solo singer in the entertainment industry, protected by the top international racer, courted by the heir to a multimillion corporation, and loved by her billionaire grandfather who wanted her to inherit the family business.Even Second Master Lu said to her, “Hold up you little brat, I think you should come home with me.”Rumor had it that Second Master Lu was handsome and beyond any girl’s reach until that one fateful day, when someone saw a drawing of a cool and proud young boy with bangs covering his eyes fall out from Second Master Lu’s book.The news spread like wildfire overnight, and on the next day, Second Master Lu was questioned. Ning Li coincidentally passed by, and upon considering her relationship with him in her past life, she stepped in and shut down the busybodies.Lu Huaiyu stared at the girl before him as he subtly put away the love letter in his hands and said with a smile, “I shall repay you with my body for saving my life.”A long while later, Ning Li saw herself in that particular drawing and she was silenced. She knew it was all a huge mistake.

She, the tribe leader of the Miaojiang witch tribe, was reborn as a pitiful little girl that everyone could bully.
