Zhuo Chuan's faces were not very good-looking, and they were not in a hurry to continue to walk forward.

"These bones were very powerful and profound. Ye Yunfan tried to attack a severed bone, but found that its quality was quite hard, and when the spell fell on it, it could only leave a trace of nothingness.

Zhuo Chuan stepped on the black sand and gravel on the ground with his foot, and couldn't help but have a thought of disbelief in his mind.

"This black sand, it must have been formed by the shattering of these broken bones. ”

Faced with this sudden thought, he was terrified, and shook his head to warn himself that it was impossible.

"There is a ground crack fire in the black desert, and ordinary bones simply cannot withstand it, and will turn into ashes in the fire, unable to take on the appearance of sand and stone. ”

Su Ze squatted down, reached out and grabbed a handful of black sand stones, and put it in front of his eyes to observe it carefully.

"Of course, if the bones are hard enough for the flames to burn to ashes, and the explosion of the earth-splitting fire can burst the bones......"

"Such a black sand will be formed!" Ye Yunfan frowned and took Su Ze's words.

"The strength of the deceased before his death must be at least the six profound realms!"

Several people frowned, and in the face of such a phenomenon, they didn't know whether to continue to move forward, and it was difficult to choose.

If these bones were all rushers like them before they died, then there must be some amazing danger in this black desert, and with their strength, most of them would die if they broke through.

"It's easy to know this, dig down, if it's really black sand and gravel formed by the broken bones, then there must be countless bones under the ground. Zhuo Chuan came up with such an idea.

This kind of speculation is too fantastical, such a vast and vast black desert, if it is like that, how many people will have to die?

There may not be enough creatures in the entire five states and three rivers!

Thinking of it, Zhuo Chuan and Su Ze used magic to break through the soil layer and dig into the ground.

The sand is hot and dry, and there should be a ground cracking fire around this small sand dune, and the deeper you go, the warmer the sand and gravel become.

At a depth of about a zhang, the black sand was already a little hot, and only the monk's body could withstand it.

Ye Yunfan and the others also helped, and they also wanted to know what the hell this place was, otherwise they would feel uneasy.

Bang!

After descending more than a foot deeper, Zhuo Chuan's spell hit something hard and could not go any deeper.

When Su Ze and the others heard the prestige, their eyebrows instantly locked.

Because it was a huge bone, like the bones of some mountain-like beast, it was extremely hard and still well preserved.

"I kind of want to go back......"

When they cleaned up the area, they found that in addition to the huge animal bones, there were also dense bones of various other creatures in this area.

Paved all over this area, there are many more in the depths.

This is not a black desert at all, but a place of cremation!

The entire black desert may be a prehistoric mass grave, with countless corpses piled up and no end in sight.

And the existence of the earth cracking fire burned some of the bones into ashes, exploded into sand, and dispersed the endless rotting and dead air......

"What kind of place is this?" Su Ze and Zhuo Chuan both looked at Ye Yunfan, the two of them were natives of Wuzhou and Sanchuan, and they knew at least more than them.

In the vast desert, if all living beings are formed after death, then how many races must this be?

They were dizzy and didn't dare to think about it anymore.

Ye Yunfan was also shocked, the primitive wilderness has always been a forbidden place in the five states and three rivers, and there are many people who have entered this place, but only a handful can completely retreat.

If it weren't for the fact that something happened to the ancient beasts and fierce birds in the Great Wilderness this time, and with the help of Puluo Tea, the four of them would have reached the end of Chifeng Forest.

This black desert of unknown origin has never been mentioned before.

He and Ye Liuying were also people who had experienced a bit in the primitive wilderness, although they were limited to the sea of flowing fireflies, but later they still saw some places when Meng Yinfeng took them away.

Can be a black desert...... It appeared as if out of thin air, and the two of them had no impression.

It stands to reason that such a vast and boundless place, even if it is thousands of miles away, should have been able to see it when he flew away from the primeval wilderness with his master Mengyinfeng.

"Go back!"

None of them were reckless people, and after seeing the true face of the black desert, they also knew that they couldn't go any deeper.

The strange crematorium hill must be the realm of the dead souls in the depths, and it must be the Jedi of the living!

The four of them have only been in the desert for a few hours now, and they are still on the edge, so they should not encounter unknown weirdness.

"Go back and go around the gravel beach. ”

They turned around and left, it was impossible to force their way into the desert!

This kind of place, maybe only an existence like Meng Yinfeng dares to go deep!

They did not linger long, but returned the way they came.

This land is too demonic, and there are bones everywhere under the ground, which can be traced back to a very old age, all of which are more than a thousand years old.

Ye Yunfan frowned and pondered, he was recalling the history of Wuzhou and Sanchuan, whether there was a great turmoil in which there was a great upheaval of the destruction of living beings.

"Two thousand years ago, the border wilderness alien tribes invaded on a large scale, and there was a shocking war with the monks of Sanchuan in Wuzhou......"

He thought about it, but immediately shook his head and vetoed it.

Not to mention that the war took place in the border desert, even if the bones were piled up here, it would be impossible to form such a crematorium, and the number was unequal.

The vast black desert is boundless, even if it is not enough to bury the monks of the entire five states and three rivers!

"I remember that the old man Zhaohua mentioned a saying," Zhuo Chuan frowned, recalling, "He said that this is the Zongwu Prison, a cage of heaven and earth......"

This is what the old man Zhaohua once said, and they were all inexplicable at the time, but except for some surprise, they didn't delve too deeply.

After all, he is not a native either, and whether you are in the secret realm or in prison, Zhuo Chuan doesn't care much.

Now it seems that this place may really be as the old man said, an ancient prison composed of the secret realm of heaven and earth, locking all the creatures of the five states and three rivers and the border desert.

Unconsciously, they had returned to the land of the gravel beach, looking back at the vast black desert, Zhuo Chuan and the four of them all had palpitations.

I really don't know what's in the innermost part of it, the earth made of endless bones, and the devil knows what will be bringing.

"What should we do now, go around these gravels?" Ye Liuying stood on tiptoe and looked into the distance, asking uncertainly.

This area is very vast, and I don't know how big it is, and if you want to go around it, you will waste a lot of time, and I really don't know how long it will take to get out of the desert.

Several people looked at each other, Zhuo Chuan and Su Ze shrugged their shoulders, and spread their hands helplessly: "That's Nengru, although I know that this line of work must be dangerous, but I can't take the initiative to find death." ”

"The black desert is strange, let's go around, we don't have to go in. Ye Yunfan's eyes lit up, and there were special symbols flickering in them, and he was measuring the gains and losses of the two.

"We don't have a lot of time, and if we don't get there in three months, eighty percent of them will be torn apart by the angry ancient beast and the wild bird, and the flesh will be taken to wrap in the belly. He shook his head and said.

Zhuo Chuan and the others couldn't help but chuckle in their hearts when they heard this, not understanding what this sentence meant.

"The reason why we have come this way, and the reason why it seems so easy is due to the help of Puluo tea, but it is also time-sensitive. Ye Liuying pinched her fingers and explained.

"How long?"

"Half a month, counting from drinking Puluo tea, the effect will plummet after half a month and disappear quickly. Then we won't be able to get around as easily as we did before."

Puluo tea is not a secret technique, unless it is drunk for a long time, the effect of melting into the nature of heaven and earth will always have a time limit.

Ye Liuying's words are popularly said that after the effect of Puluo tea disappears, they have to kill all the way and force themselves into the primitive wilderness.

"What is the time limit of three months?" Su Ze asked Ye Yunfan, and what the latter said seemed to have little to do with what Ye Liuying said just now.

"Three months is the period when the ancient beasts and birds in the primordial wilderness sleep, after this time, the master's methods can no longer be suppressed, and when the time comes, these angry races wake up, and the first to clean up are those of us who have broken into their territory. The Flowing Firefly Fairy didn't sell it, and continued, "So if necessary, we still have to pass through here." ”

She pointed to the magnificent desert in front of her, and shrugged her shoulders like Zhuo Chuan and them before, quite helpless.

"Then how far are we from the end now?" Zhuo Chuan and Su Ze asked in unison, they came to the Secret Realm to find an opportunity and pave the way for the future, not to die!

"I don't know, I haven't been to the Ultimate Place......"

"Then do you know the way?" Zhuo Chuan touched his nose.

"Master said that going all the way to the deepest part is the ultimate place!" Ye Yunfan took over the words and said with a firm expression.

As long as it was what Meng Yinfeng said, he believed it.

But Zhuo Chuan and Su Ze had a pig's liver on their faces, God knows if the Dream Ancient Saint is reliable or not, they don't want to give their lives here.

But they had already made an oath that they must escort the two of the Ye family to the altar land, otherwise they would be counterattacked by the Great Dao of Heaven and Earth.

"Let's go, let's not waste time, it's better to hurry as soon as possible. Zhuo Chuan sighed in a low voice, recognized the reality, and urged everyone to leave early.

They made their way along the gravel beach, no longer too deep into the desert for fear of attracting some unknown horror.

I don't know how the gravel beach was formed, as if it was created by man, and it doesn't look like a natural thing.

On one side is the vast wilderness, the ancient timber wolf forest, the mountains and rivers under the sky, the mountains and mountains are horizontal, shuttling vertically and horizontally, and on the other side is a lonely black desert, like the end of the world, the extinction of living beings.

Zhuo Chuan and the four of them tried to hurry as fast as they could, but they also had mana, just in case.

The gravel beach is very long, surrounding the desert, as if it stretches all the way to the place where heaven and earth meet.

The road was silent, and not even a single bird or finch had been seen along the way, as if stepping into the forbidden area of life.

As the days passed, the effect of the Puluo tea on their bodies began to disappear, and the aura that melted into heaven and earth quickly dissipated.

"It's been half a month since we entered the primordial wilderness. ”

The last time they drank Puluo tea was on the day they set foot in this great wilderness, after all, it was too wasteful to drink it too early.

But even so, they did not encounter any ancient fierce beasts on the edge of the gravel beach, as if this was an isolated world, and no creatures of the primitive wilderness were willing to come.
