In his lower abdomen, a flame slowly rose from it. At first, Gu Yuan could only feel a hint of warmth. As the technique was practiced, the flame gradually grew larger and gradually formed a ball of fire. It was still burning with spiritual energy and spreading from the lower abdomen, to the torso, to the limbs, and finally all over the body.

"Kid, hold on. If you make it through this time, you'll gain more than just this little benefit!"

The golden-haired vulture was a little worried. It flapped its wings and completely sealed the cave entrance, plunging the entire cave into darkness.

The expression on Gu Yuan's face gradually became painful. At this moment, his body was full of flames, and they were constantly spreading outward through his pores.

The clothes and hair on his body turned into nothingness, and he eventually turned into a man of fire.

In the darkness, blood-red flames covered his entire body, from the initial low hum to the painful groan, and finally turned into a heart-wrenching and desperate beast roar.

Pain! Heart-wrenching pain!

Gu Yuan had never felt such pain before. The flames devoured him like a prehistoric beast, crushing him, giving him new life, and then devouring him again, repeating this over and over again...

“Ahhh…”

After an unknown amount of time, the painful roars of beasts filled the entire cave. Gu Yuan pounded the ground frantically, and eventually his entire body crashed into the stone wall. After countless collisions, the entire stone wall of the cave had turned blood red. Gu Yuan fell down powerlessly, and the blood red color of the flames on his body gradually became transparent at this time, and finally all of it was absorbed into his body.

"Is it over?"

In the dark cave, one could only see the golden-haired vulture's pair of calm eyes.

There was a hint of excitement in its voice; it knew that Gu Yuan was not dead.

As long as you don’t die, you’ll have achieved 90% success!

"Just waiting for my body to be reborn..."

The golden vulture closed its eyes again and waited quietly.

At this time, Gu Yuan was naked, his entire body was charred black, without a single piece of good flesh on his body, and he was utterly battered.

But beneath the charred black, transparent flames were sweeping across his body again and again, and wherever they passed, new granulations of flesh were slowly growing...
