Chapter 635: Breaking Through to the Late Stage Small Origin Core Realm

Zhao Feng didn’t use the Dark Heart Seal on the skeletal Division Leader.

The Dark Heart Seal had its advantages and disadvantages.

The main advantage was that the target would fully obey the user, but they would become something similar to robots. Their minds and way of thinking were limited, and they would have limited potential.

Therefore, Zhao Feng didn’t use the Dark Heart Seal on the skeletal Division Leader. The latter’s cunning was better than a mere doll that knew how to take orders.

Furthermore, the skeletal Division Leader wasn’t much of a threat to Zhao Feng anymore at this point anyway.

Besides, the Dark Heart Seed already in its heart could still decide its life or death in just one thought.

After comprehending more than a dozen new skills, Zhao Feng’s seclusion still wasn’t over.

“There’s still two more months left. I need to strengthen and consolidate my cultivation.”

Zhao Feng closed his eyes and continued to cultivate.
