I'm in Zeta, and My Future Wife, Zero, Is Yuka!

Zhang Hui traveled through time and became Zero, came to the world of Zeta, bound to the strongest righteous system, and gained all the strength and special abilities of the Demonic King at the beginning. In order to end the era of great villains opened by the God of Villains, Zhang Hui killed all the great villains and was known as the Mysterious Five. His reputation spread to the Ultraman multiverse and struck fear into the hearts of countless villains. An unprecedented look of fear appeared on Shafrin's face: "Sero is the most terrifying madman in history. In order to take revenge on me, he destroyed my strength and body, and sent a hundred volcano monster birds to take turns poking my butt with their mouths, and burning my head with flames, making me a joke to all the villains in the universe!" Beria said angrily: "Zero, where is your Ultra spirit? In order to get revenge on me, you asked my son Geed to kill me ten thousand times. You are more perverted than the God of Villains!" "The Ultra Spirit is used to treat good people. I will always use any means to deal with villains!" This novel and its characters are purely fictitious.
