After I stopped trying, a rich woman trained me into a demon emperor.

In a chance encounter at the gym, Zhou Ran, a young and skilled martial artist, is unexpectedly approached by his friend's mother, Ms. Chen, with an unconventional proposal: she will buy out the gym for him if he agrees to continue training. However, Zhou Ran's priorities are turned upside down when he witnesses his girlfriend, Su Xiaoxiao, and his best friend, Zhao Tao, passionately embracing in a luxury car. Feeling betrayed and hurt, Zhou Ran rejects Ms. Chen's offer and declares that he will no longer continue his training. To his surprise, Ms. Chen presents him with an heirloom ring containing the remnant soul of an ancient being, marking the beginning of Zhou Ran's unconventional journey as a demon emperor.
