As a kind of punishment, the wings of a demon king were cut, and he eventually lost all of his power. To get back his power, he made a deal with the angel. He will go to the realm of humans to find a special girl with a special skill who is meant to be her queen. If the woman got pregnant, all of his sins would be forgiven, and he will regain all his powers. But he didn’t think that knowing her would be an adventure for him as the king of demons in the human realm.

Li Qi, who originally believed that even after being reborn in another world, he would still spend his life in mediocrity, unexpectedly gained the ability to track his progress on the path of cultivation. This rekindled his ambition and gave him the courage to embark on the journey of seeking The Way. A man with a determined heart should strive to overcome mountains and rivers, creating ripples that stretch for thousands of miles as he pursues enlightenment and mastery over his own destiny.
