Of the gray werewolves that Chen Feng had previously contracted, three of them have now died!

This sudden change caused a gap to appear in the originally tightly connected power system, leaving three of his precious slave seals empty.

However, Chen Feng did not panic or hesitate in the face of this situation.

After careful consideration, Chen Feng resolutely made a bold decision:

He intends to kill the remaining three surviving gray werewolves, and then use the vacant slave seal to contract with the more powerful and ferocious Black Lightning and other black werewolves.

In particular, the black werewolf with the strength of a sixth-rank cultivator brought by Hei Cang became a target that Chen Feng was determined to obtain.

This decision was undoubtedly fraught with risk, but for Chen Feng, only by constantly pursuing greater power could he remain invincible in this perilous world.

These incredibly fierce black werewolves might just be the key to his path to the top.

At the same time, these powerful black werewolves will become part of Heicang's core group, helping Heicang compete for the position of heir in the tribe and obtain more resources.

"Hei Cang pays respects to his master." After the slave mark was successfully imprinted, Hei Cang knelt down respectfully.

"Don't worry, I will prepare a group of loyal subordinates for you." Chen Feng nodded, then went over and killed three fifth-grade gray werewolves, and then formed a contract with three fifth-grade black werewolves: Black Lightning, Black Blade, and Black Ball.

Of the remaining three sixth-rank black werewolves, Chen Feng killed the one with the most severe injuries and made a pact with the other two with lighter injuries, thus turning all nine servants into black werewolves.
