The martial arts legend Guo Jing (here is a setting, not a character in Jin Yong's works), fell unexpectedly when he was attacking the holy realm of martial arts, and was reborn back to his boyhood. In his previous life, he became a legend on the mainland with his tenacity and extraordinary talent, but he regretted his life because he failed to protect his relatives and friends. In this life, he protected his relatives and friends in advance, practiced supreme martial arts skills, made friends with heroes from all walks of life, and finally broke through to the holy realm of martial arts and became an immortal martial arts legend.
