These cultivators controlled by He Song, their abnormalities naturally wouldn't be detected by other Divinity Transformation cultivators.
In this way, if He Song truly wants to make a big move.
He might just be able to completely render the Divinity Transformation cultivators within these Holy Lands powerless.
However, He Song wouldn't do such a thing.
By placing a few hidden pawns within each Holy Land, he can control all changes within these Divinity Transformation Holy Lands.
As long as these Holy Lands don't affect He Song, he would at most rely on their intelligence networks to understand the outside world better.
As for doing anything else.
He Song has no such intentions.
Moreover, if he really controlled too many of them.
It might increase the risk of these people being exposed.
It would be truly not worth the loss.
However, if He Song truly manages to accomplish this.
Then.
He might be able to have the entire Cultivation World at his fingertips.
