Yu Daomin, the Beidou swordsman, became one of the top ten masters in the world when he was nearly fifty years old. However, he was willing to give up all glory to save his seriously ill only son and became the "Golden Swordsman" who was a nursing home martial artist in Shijiazhuang. However, his son died, and his young master Shi Jinlong, whom he regarded as his own son, was also killed by the evil Black Sky Alliance after his twentieth birthday. Before his death, Yu Daomin only wished to protect his only family in the next life.
When he opened his eyes again, he was reborn ten years ago and possessed the body of ten-year-old Shi Jinlong. This former top master discovered that he not only possessed the legendary "Heaven-defying Body", but also mastered all the information for the next ten years. He decided to live as Shi Jinlong and change his tragic fate.
