(Dual systems, one for rebirth, one for time travel, and the other system is in the hands of the villain)
Chen Lingfei was reborn on the Earth in the Corner Universe. There are no monsters or Ultraman here. Of course, as a time traveler, he also has a system, but this system is a failure. It only gave Chen Lingfei the ability to transform, and there was nothing more. He was not given tasks or allowed to make choices.
Until one day, Chen Lingfei transformed for the first time and went to Mars to rescue Zero who had escaped from the Kingdom of Light, and then he became dependent on him.
After learning that Chen Lingfei was the blue giant who saved him, Zero had nothing else to do except asking him to help save the people from the Kingdom of Light every day.
Very well written
