The Strongest Mebius

My name is Nie Shen, okay, it's a very cool name. My dad probably read too many fantasy novels when he named me. Closer to home, I am a second-rate assassin. I took on a big task a few days ago, to assassinate a rich man with assets of over 10 billion. I, a second-rate assassin, had no hope of completing the task for the first time. I got paid that night and went to the most expensive health care service in the red light district. Unexpectedly, I woke up and slept on the street. I've traveled through time! There was also an extra system in my body for no apparent reason. I asked the system to send me back, but the system told me that the energy for traveling through time was used up. It also said that by seizing the source of the planes of this world, I could return to the original world. Looking at the big chrysanthemum in the sky, I actually refused at first, but the system told me that I could become Ultraman, and said I could do more stunts while doing it. Well... Very high, very cool, duang... Duang... Duang. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
