The moment Deoras said this, all the high rankers almost sighed.
They all knew beforehand what Deoras was going to say.
Well, Shin was leaving behind everyone because of the large number. This meant that they had to listen to the orders of other higher rankers who were by no means stronger than Shin.
Deoras, even if tried, couldn't possibly defeat Shin. He knew this very well and thus because of that, he instantly realized that by staying back, his chances of dying would only increase!
The Supreme celestials cannot take any direct actions, but this didn't mean that they couldn't summon storms or earthquakes to harm Shin and his men.
Therefore, Deoras, after thinking for a while, thought of this plan. He would accompany Shin with the proposal of protecting him, but in return, it would be him who would get the protection from Shin in case anything were to happen.
