In his previous life, he was a martial arts emperor who traveled across the sea of stars. He sought defeat alone, but fell at the peak. In this life, he opened his eyes and woke up and found himself in an urban martial arts world called "Blue Star". What's even more bizarre is that he is no longer the powerful man who can control the wind and rain, but an ordinary single dad with a soft and cute daughter next to him.
Spiritual energy is revived, strange beasts are rampant, warriors are like a forest, and the city is surrounded by dangers. Su Muoyun had to face the reality: the power that once destroyed the world was incomplete, and his only "mission" was to prepare milk powder for his daughter and tell bedtime stories. However, his daughter's smile ignited his silent heart. In order to protect this hard-won warmth, Su Muoyun decided to resume martial arts and start from scratch. He used the memories of his past life and his understanding of this life to stir up the situation in Blue Star as a nanny. Holding his daughter in one hand and scolding Fang Qiu with the other, he wrote a legend about father's love and martial arts in the urban steel jungle.
