Cao Ji, the modern underground boxing champion, was drugged and plotted by his opponent Liu Hao six years ago. His right leg was disabled and he has since retired from boxing. While hiking to relax, he accidentally fell off a cliff and traveled to Longyin Canyon in the Song Dynasty. In the canyon, he used modern wisdom to resolve crises, improve his skills, and heal his leg injuries. After finding a way back to modern times, Cao Ji has only one obsession: to return to modern times, find Liu Hao, uncover the truth of the past, and take back everything that belongs to him...
Purpose: Tell a story about scars, growth and return. The physical injuries can be healed, but the mental scars need to be faced and resolved by oneself. No matter what situation you are in, if you stick to your heart, make good use of your wisdom, and never forget your kindness, you will eventually find your own path and answer.
