Lin Yuan's Plan!

When Eternal Source saw Chef Supreme and Iron Prison, he hurriedly greeted them and said in a friendly voice, "We are done with all the preparations. We can accompany you back to the main world at any time! Lord Lin Yuan has already given me instructions. You just need to allow us to remain on your bodies once we have transformed ourselves!"

Eternal Source was not aware of Chef Supreme and Iron Prison's status.

Firstly, he had been by Lin Yuan's side the entire time. The only time they were apart was when Lin Yuan instructed him to take over a certain dimensional world.

He did not have the chance to interact with people from the Radiance Federation and did not understand what it meant to be a member of royalty. Thus, Eternal Source did not see Chef Supreme and Iron Prison as Lin Yuan's seniors.

Eternal Source was only polite to Iron Prison and Chef Supreme because this was a task from Lin Yuan. As such, Eternal Source would do his best to complete it.
