The Energy Sub-Core of the Wheel Realm

This person is very lazy and didn't write anything. He had to write this thing because he didn't know how to write an introduction. He is a newbie in writing and has no experience. He will give it a try. He has no pursuit. He just hopes that the results will not be too ugly. If the results are good, he will continue to update in the future. I actually want to write more. After all, it is a day of putting into practice the ideas I have always had. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
