Gu Qingfeng, who had fought bloody battles in the vast galaxy for thousands of years and finally became the supreme master of martial arts, thought that he would retire with success, but when he opened his eyes, he found that he had returned to a parallel world called "Blue Star". There is no cruel practice world here without swords and shadows, but there is an urban martial arts that coexists with the mortal world. What catches him even more unprepared is that he has become a "waste" dad who has just experienced the pain of losing his wife and has a cute daughter.
The former martial arts heart was rekindled in her daughter's clear eyes. In order to give his daughter the best life and the safest harbor, Gu Qingfeng decided to resume his old skills, taking parenting as his way and protecting him as his thought. From ordinary urban life to the undercurrent of the martial arts world, he took care of his children with one hand and pushed him with the other, rewriting destiny with his peerless force and creating a legend with his father's love.
When the shadow of Xinghe's old enemy gradually approached, and when the secrets of Blue Star Martial Arts were revealed layer by layer, Gu Qingfeng discovered that what he was guarding was far more than just a daughter, but the future of the entire galaxy.
