[Time travel, urban invincibility, fantasy, multiple heroines, cool writing]
The Demon Emperor fell and unexpectedly reborn in the city.
While he was in a coma, he was accidentally discovered by the Dragon Kingdom's military to have a special physique and was recruited into the army for human experiments, but no progress was made.
When the Demon Emperor wakes up, the Dragon Kingdom takes the initiative to befriend him, and the Demon Emperor and the Dragon Kingdom reach a secret treaty.
The Dragon Kingdom concealed his identity, gave him a new identity, and then helped him find his way home. The Demon Emperor helped the Dragon Kingdom sit on the border. The Dragon Kingdom with the Demon Emperor sitting there became a nightmare for the world. No country dares to commit crimes. When the Dragon Kingdom dominates the world, the Demon Emperor retires from the military career, returns to the city, and begins a life of debauchery!
