The Dark Wolf Emperor took two courses of action.

The Dark Wolf Emperor had not discussed this with Qin Feng.
He was just finding an excuse to collect "protection fees" from those local guilds anyway.

If more payment was needed, he could simply ask those guilds for more.
The second was targeted killing.
In particular, after members of the other two leading guilds were forced to come "work" in these two ancient forests, the Dark Wolf Emperor would create opportunities to isolate them, then kill them!
After killing them, he would have the Demon Metal Wolves under his command devour all the tradable lifespan from their corpses!
