Traveler Time and Space Manager

At the beginning of Hongmeng, the great road was opened, but the great road retreated and the way of heaven came out. Before he was 20 years old, Makuro was wondering who and how people traveled through time. Don't we care about the great road and the way of heaven? Are we not afraid of destroying the balance of the world just by casually swearing an oath and making a promise? After 20 years old, he understood when he was selected by Hongmeng Taoist to be the manager of time and space. This is my first time writing a novel and I don't know how to write it, so I just read it myself, so that's it. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
