"Come back here!"

After being devoured by the spatial black hole, Ye Zichen immediately summoned everyone back to the Cosmos Sack, in order to prevent them from getting hurt by the sharp spatial cracks.

After about ten breaths of time, Ye Zichen passed through the Cosmos Sack and found himself in a desolate space that was filled with aura of death. He took a simple break, recovering his depleted soul power and injuries, then appeared outside.

"Sigh, let's check out this space first!" Ye Chenfeng sighed, then chose a direction and flew into the depths of the space that the training hall had evolved into.

"Bones, why are there so many bones here!"

When Ye Zichen passed through a long and narrow canyon, he discovered that the canyon was filled with countless corpses. There were large and small skeletons, and there were people and demons, two of them were white bones, several hundred meters long. The sharp bones were like swords, piercing through the sky and emitting an extremely terrifying aura.

"Mm, is this the skeleton of a Saint Beast?"

As he flew, Ye Zichen saw an unimaginably large skeleton scattered within the depths of the canyon. Every single bone was over a hundred zhang long, or even a thousand zhang long.

More importantly, the huge skeleton also emitted the pressure of a Saint Beast, causing Ye Zichen to suspect that it was a Saint Beast skeleton.

"Crack!"

Just as Ye Zichen landed beside the skeleton and wanted to move a huge bone spur, a series of cracks suddenly appeared on its surface. In the blink of an eye, the skeleton, which had been eroded by time for who knows how many years, turned into bone dust and dissipated in the wind.

"Sigh, the life essence of this Saint Beast's skeleton has already been lost. There's no more value to it!" Looking at the decomposed skeleton of the Saint Beast, Ye Zichen let out a sigh, while revealing a look of regret.

After Ye Zichen flew out of the canyon, which was filled with large amounts of bones, he continued to fly towards the desolate space in search of an exit.

Suddenly, he felt the space in front of him become restless. Tens of thousands of soul forces drilled out of the grayish-brown ground and filled the space, forming a black storm that covered the sky and the earth, sweeping towards him.

"Soul Storm!"

Ye Zichen did not reveal any expression of panic as he looked at the incoming soul storm. He did not hide in the Cosmic Realm, but sat cross-legged on a hill and silently watched the soul storm that was emitting an ear-piercing ghost cry come closer and closer, engulfing him.

In the midst of the soul storm, Ye Chenfeng immediately felt tens of thousands of dead souls crazily biting his flesh, wanting to devour him and drink all the blood in his body.

However, his physical body was comparable to an ancient Dao treasure. When he executed the Golden Body Incantation, a layer of defensive golden light covered his body. The departed souls within the soul storm could no longer harm his physical body.

"Devouring God's Brain, Devour!"

As he endured the densely-packed soul devourer, Ye Zichen immediately controlled the brain to appear within his soul realm, turning it into a black hole that crazily devoured the soul in the soul storm.

The God Devouring Brain was the nemesis of all souls. As it crazily devoured, the God Devouring Brain began to divide into brain cells, constantly growing.

"Yin …"

Suddenly, a piercing sound rang out in Ye Chen's soul sea. Ye Chenfeng suddenly opened his eyes, and saw that in the soul storm, which was as black as ink, there was a soul storm that was several hundred meters long. It was covered in thick scales, and there was a single horn on its forehead.

"Soul transformation!"

As he looked at the Horned Dragon that was attacking him, Ye Zichen's eyes, which were as sharp as lightning, saw that the dragon did not actually exist. Instead, it was formed from thousands of dead souls, yet the energy it contained was extremely terrifying.

As the soul dragon attacked, Ye Zichen raised the power of his God Devouring Brain to the limit, while continuously expanding the illusory spatial black hole, and devoured the flood dragon that was releasing the light of its soul.

"Aooo!"

Under the crazy devouring of the soul devouring brain, the giant body of the soul flood dragon was continuously minced.

In just ten breaths of time, the Godeater Brain swallowed up the soul flood dragon and continued to divide it into brain cells.

Soon, an hour had passed. The soul storm that had swept through the world gradually dissipated, revealing Ye Chenfeng, who was still sitting cross-legged and completely unharmed.

The Godeater Brain had devoured tens of thousands of souls and divided a large number of brain cells. However, as the Godeater Brain transformed over and over again, it needed more and more energy.

"I wonder when this training hall's space will turn into a soul storm again."

Facing the soul storm that caused people's hearts to tremble, Ye Chenfeng revealed an expression of anticipation. If he allowed the mind to continue to devour, it would definitely evolve once again. At that time, the chances of him leaving this damn place would greatly increase.

With great anticipation, Ye Chenfeng continued to fly in the training hall. Not far in front of him, he found a mountain wall that was as smooth as a mirror. Below the mountain wall, there was a line of bold and powerful calligraphy, as well as a dilapidated ancient array flag.

"I, the Great Sine Heavenly Saint, know that I won't be able to live long. I will leave the mid-grade saint artifact, the Black Crow Sacred Flag, to the fated one. Hopefully, one day, the Black Crow Sacred Flag will reappear in the world."

As he looked at the inlaid ancient characters on the mountain wall, Ye Zichen's eyes immediately lit up as he looked at the tattered ancient array flag.

"Could it be that a Heavenly Saint has died here, and he left behind a mid-grade saint treasure?!"

With his current strength, he could use half of a mid-grade saint treasure's power. It didn't consume much energy, so it could be said that a mid-grade saint treasure was even more useful in his hands than a top-grade saint treasure, the Nine Dragons Jade Wall.

"Younger generation, if you do not wish to die, then do not approach that ancient formation flag." Suddenly, a low voice sounded out in Ye Zichen's ears.

"En, there are still undead people in this space!"

Ye Zichen raised his eyebrows and revealed an expression of surprise. He immediately used the mind devouring to sense his surroundings, but did not discover the person who sent the soul message.

The temptation of the Black Crow Divine Flag was too great. He thought for a moment before walking towards the mirror-like mountain wall.

Seeing that Ye Zichen did not listen to his advice, the mysterious voice did not speak again.

When Ye Zichen reached out his hand to touch the Black Crow Divine Flag that was embedded in the wall of light, endless black light spread out from the holy flag, sealing the space around Ye Chenfeng.

The next moment, a crack appeared on the smooth wall of the mountain. A white-haired old man with shriveled skin walked out from the crack.
