Slutty Mouth has been a small lord for quite some time now and has never left his territory.
Even after he decided to strive for progress and set up a caravan business for his descendants, he still indulged in pleasure and never left his nest.
He is definitely a purebred shut-in.
Being a mascot for the Celestial Emperor is no problem for him.
Moreover, with the system in place, this Celestial Emperor doesn't have much authority and has to follow the rules, so there's no concern about unexpected mishaps.
Now, integrating Slutty Mouth's Great World into the Celestial Realm to strengthen the weakest link in the Heaven, Earth, and Human Three Realms was something agreed upon long ago.
Slutty Mouth didn't even ask for details, agreeing unconditionally because he knew the boss wouldn't shortchange him.
With the collaboration of Slutty Mouth, the Master of the Great World, the integration of the Tree Man Great World progressed extremely smoothly without causing any ripples.
