Starting from Traveling to Ultraman and Developing BOSS

I saw that although there are many people writing Ultraman fanfics, not many people write about raising monsters, so I will try to write one. If you don't like it, don't criticize it. The content introduction is that the protagonist Ye Tian traveled to the world of Ultraman, but his system asked him to raise BOSS-level monsters, and then required the Ultramans to defeat the monsters he raised. Ye Tian was speechless, but he had no choice but to start the hard-working BOSS training plan. And the first monster he developed was the super centipede monster-Sildoros. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
