They were also supposed to scout the realm trees to find vulnerable ones. Then they would bring the information of their chosen realm tree to the realm lord who would then help them to suppress it.

They have a lot of reasons to complain. But none of them said a word when Monarch High Heaven waved his hand at a realm tree. Space was twisted by a mysterious force and the barrier of the realm tree was shredded.
There was no fanfare or fire works even though this is a large realm not a small realm. It looked as if he had put in very little effort but they know that to be false because they felt the mysterious force that assaulted the realm tree. It was vast like an ocean. It could drown out all 500 million of them just as easily as it shredded that barrier.
