Gu Xinghe, the former Galaxy Martial Emperor, was in charge of all realms and the sea of stars. However, he fell due to a shocking conspiracy, and his soul fell into the abyss of "Return to Ruins" that will never be restored.
When he opened his eyes again, he was no longer the supreme being overlooking all living beings. Instead, he returned to a strange modern city. Time went back and he became a penniless single dad with a young daughter.
What shocked him even more was that the person he was holding tightly in his arms with tears in his eyes was actually his own daughter, Gu Xiaonian, who he failed to protect due to his negligence in his previous life.
Under the city, undercurrents are surging. Ancient martial arts families, hidden extraordinary organizations, and threats from other dimensions are just around the corner. Gu Xinghe discovered that although his once supreme martial arts had been eroded by "Guixu", it had not completely dissipated. Instead, it had a strange resonance with the city's thin spiritual energy laws.
For the sake of Xiao Nian, he was willing to wash away all his glory, let go of the arrogance and coldness of Emperor Xinghe, and become his daughter's most solid guardian angel.
The domineering power that can break the stars with one punch, and the gentleness of caressing a young girl with one hand.
He wants to return to the pinnacle of martial arts in this seemingly peaceful city but actually hides murderous intent, expose the monstrous conspiracy of his past life, and let his daughter Gu Xiaonian live the happiest and safest life.
However, when he discovered that his daughter Gu Xiaonian seemed to possess some extraordinary talent, Gu Xinghe's life as a nanny was destined to no longer be ordinary.
Returning to the ruins, only for one person. Kill everyone in the world, just to protect!
