This change happened extremely fast, completely beyond thinking. In just an instant, all the blood in Fang Yun's body was absorbed and replaced by the blood essence of the ancient ferocious beast Fei.

Pain, indescribable pain!

It was like being torn apart and then bitten by countless ants and insects. After Fang Yun obtained the essence and blood of the ferocious beast, he had never performed the method of earth transformation, and he had never thought that performing the method of earth transformation would be so painful.

Despite the pain, Fang Yun did not roar, but suppressed the painful feeling with an inhuman will.

"boom!"

When the pain reached its maximum, Fang Yun felt a sudden shock in his mind. His spirit and will suddenly expanded infinitely, to an incredible extent in the blink of an eye.

"Buzz!"

In the mist, Fang Yun felt that he had touched some mysterious and indescribable rules between heaven and earth! ...

"Boom!"

The mighty vitality of heaven and earth poured into Fang Yun's body at a terrifying speed. At the same time, in the ninth underground world, the majestic power was pulled out of the surface by some rules and turned into strips.

A substantial dragon penetrated into Fang Yun's hole.

Thick black smoke rose from the ground and quickly submerged Fang Yun.

"hold head high!--"

A loud roar, as if from distant antiquity, sounded from the center of the battlefield. The ground shook violently. The black mist exploded, and the fierce and domineering ancient plague beast "Fei", nearly a thousand feet tall, reappeared in the sky again.

Fei has an ox's face and a white head, one eye and a snake's tail. If it walks on water, it will be exhausted, if it walks on grass, it will die. If you see it, there will be a great epidemic in the world! - "Annotations on Ancient Sutras"

In just a blink of an eye, Fang Yun completed the "method of earth transformation" and transformed from the human body into the body of a ferocious beast! However, this "snap of lightning" time seemed to Fang Yun to be a long time.

The same as a century ago!

"Beng, Tian, ​​Big, Hand Seal!"

Amidst the loud voice, a huge palm stretched out from the void around the ancient ferocious beast "Fei". With a "boom", it shattered the Fire Dragon Demon King, and the falling flames made a loud noise!
