889 Nine Calamity Battle Emperor

"Nine Calamity Thunder Prison Visualization…"

Mu Chen's eyes slowly opened, and the thunder in his mind seemed not to have completely disappeared. Then, the ancient thunder script was imprinted on his mind like a brand.

Although he did not take a closer look at the so-called, "Nine Calamity Thunder Prison Visualization," for some reason, he was able to faintly feel a sense of rage and oppression in his mind.

Such a technique was bound to be unusual.

When Mu Chen opened his eyes, the Sky Array Emperor looked at him in amazement and then slowly said, "I didn't expect you to have such a high degree of compatibility with it."

"Master, what are the origins of the Nine Calamity Thunder Prison Visualization?" Mu Chen asked curiously. Judging from the Sky Array Emperor's reactions, it seemed that this technique had a marvellous origin.
