Proving the Dao, Saying the Law

He sat cross-legged on the peak of the Supreme Sacred Mountain, his eyes flashing with wisdom.

After an unknown period of time, a huge heart appeared in Li Lingtian's hand. The heart was blood-red with a tinge of light purple. It was glowing with a faint radiance and it was still beating rapidly.  

Just as the heart appeared, the forbidden ground of gods and devils trembled, and demonic qi soared into the sky.

Every time his heart beat, it would cause all the Demon Spirits and Gods in the forbidden grounds to tremble.

This was the Demon God's Heart.

Gradually, the beating of the Demon God's Heart merged with the Demon Realm. At the same time, Li Lingtian's mind began to beat as well, influenced by the Demon God's Heart.  

"Entering the Dao with the Devil, attaining the Heavenly Dao."

He slowly closed his eyes and entered a state of emptiness.
