Chapter 510: Xia Family's Ancestor

"Emperor, why didn't you let me kill him?"

Just after Xu Nian had left.

An old man emerged from the Chengtian Hall.

This old man exuded a strong presence of the Half-Emperor Technique.

Clearly, he had been ambushed in Chengtian Hall long before.

His purpose was to strike at the critical moment and deliver a fatal blow to Xu Nian.

He had been prepared to face the Heavenly Punishment.

However, the Emperor ultimately ordered him not to make a move.

The Emperor, upon hearing the old man's words, furrowed his brows, his eyes filled with dense unwillingness.

"That young man has a terrifying aura. I clearly felt a powerful soul fluctuation sweep over me just now. Didn't you fail to find out earlier that the young man was released from the seal by Old Eight's subordinate, the One-star Battle Emperor and still wasn't killed? I think I might already know the reason," the Emperor said, looking in the direction Xu Nian had left.
