"Boom!"

The sand rose, and the irritable aura spread, and the corpse of a monster fell into the dunes.

Only half of the body is exposed.

The blue blood that spurted out of the exploding wound looked very beautiful in the orange-red skylight.

"Whew." Cheng Lin exhaled deeply and slowly lowered the sword in his hand.

After checking the consumption of the sword just now, he had already drained more than one-third of the aura reserves in his body.

The consumption of He Jian's sword qi is as huge as ever, but the effect is also quite good.

Piercing the pitch-black iron sword into the sand, Cheng Lin wiped his sweat with the hilt of the sword, and then looked at the dead five-rank monster with great satisfaction.

Yes, five pins.

Originally, it was a "beast fishing" according to the convention, but I didn't expect to provoke a big guy.

Fortunately, Cheng Lin has enough hole cards, but it is not a big problem.

It's just that when this thing sees that the situation is not good, he turns his head and wants to flee from the ground, so he can only send out a sword and kill it.

"Now the main material is here."

Cheng Lin wiped away the sweat, and then thought happily.

One of the main materials required for the Spirit Gathering Ritual is the body of a five-rank creature.

Manipulate the combined spirit and put away the scythe.

went to absorb the other party's soul energy and restore the loss, Cheng Lin dug out the crystal nucleus and moved the corpse into the spirit world, which was a complete relief.

The buggy was parked aside.

Cheng Lin washed his hands with water, and then leaned on the front of the car tiredly and squinted his eyes ahead.

At this moment, it is already evening.

The desert is lonely, and the sun sets over the long river.

I didn't see Lone Smoke, but the rest of the scenery was complete.

In the boundless desert, the meandering river is much wider here, and you can still hear the sound of rushing water when you listen carefully.

In the open field of vision, a huge red sun hangs over the horizon, releasing the last of its heat and rendering the whole world in a dusk and brilliant color.

If it is far enough apart, the car and Cheng Lin will become a pitch-black silhouette.

Combined with the sunset over the desert, it is bound to be a good scenery to photograph.

However, Cheng Lin's mood at the moment was not beautiful, and he was even a little worried.

"I've only gotten a total of twenty fourth-grade demon cores now...... There is also a five-grade ...... And seeing that the projection is halfway gone, I'm afraid I won't be able to achieve my goal if I continue like this...... Although this goal is a bit too big in the first place. ”

Lean against the side of the car.

Cheng Lin was carrying a pocket in his hand, and at this moment he was seriously counting the number of crystal nuclei in it, and then his eyebrows were twisted into the word "Chuan".

After bidding farewell to the small lapels of the five divisions, he was also diligent along the way.

In addition to the normal exploration mark, it is to attract Sipin to hunt, but until now, the results have made him very dissatisfied.

No, it should be unusually dissatisfied!

Twenty...... It's too far from three hundred.

Of course, it's understandable when you think about it.

After all, he was only one person, and considering that the large army behind him did not dare to stay in one place for too long.

Even if you attract it with flesh and blood, there is a high probability that it will attract some creatures with less than three grades, after all, four grades are not everywhere in this desert.

However, up to now, Cheng Lin has also found that the level of biological strength in this projection is not high.

Seeing that he was about to come to the core area, the strongest monster he encountered was only a fifth grade...... Maybe there are higher, but maybe I haven't met them.

"It's too slow."

Putting away the twenty-one demon cores, Cheng Lin gradually began to recognize the reality.

It seems unlikely that this expedition will be able to collect all the material.

Before, he was still thinking about going to the No. 1 projection next door, but referring to No. 2, Cheng Lin felt that it was no longer necessary to go or not.

In addition, the projection has not existed for a long time, and it may outweigh the losses if you spend too much time on the road.

Raising his head, he narrowed his eyes and focused on the dark shadow in front of him.

Yes, the dark shadow standing on the horizon in front of him was the central area of the projection.

Because of the sun, Cheng Lin couldn't see clearly, but vaguely felt that there seemed to be many trees there.

This made him extremely curious.

After resting, I drank the potion to fill the aura in my body.

Cheng Lin got back into the car, stepped on the accelerator, and sped towards the central area in the face of the round sunset.

……

The speed of the car in the desert is still very fast.

Not long after, when the sunset finally began to slowly slide to the horizon, Cheng Lin also came to the outside of the central area.

Then he was stunned.

Oasis.

What appeared in front of him was a large oasis!

Verdant plants, plants and rivers come together to form this oasis that stretches for thousands of meters.

"Squeak—"

The four tires rubbed violently against the ground, Cheng Lin stopped the car, and then slammed the door and walked out, staring at the green fertile soil in front of him in surprise.

Maybe it's because of the evening, or maybe it's because of the climate here, the heat in the air is significantly reduced.

Cheng Lin could even feel the oncoming cool breeze and the moisture in the air.

"This is where the river comes from?"

Cheng Lin thought to himself, instead of rushing in, he turned on his perception ability and condensed his spiritual power into a beam to explore the past.

Immediately, the scene inside came to mind.

The sparkling river at sunset, the tender green grass, the tall exotic tree species, the leaves are full and fresh.

Some trees still bear fruit, and there is a faint chirping of small insects in the grass, but they can't feel the presence of high-grade monsters, and they don't even have the smell of danger.

The vast oasis is peaceful.

However, as the field of vision continued to extend, Cheng Lin finally discovered the anomaly.

In the grass, there were many monster bones and rotting flesh and blood.

Some were old, some were fresh, and he even saw a few that had clearly just died.

Lying peacefully in the grass, on the land, by the river.

With his eyes closed, there was no breath.

There are all kinds and grades of them, and they are scattered and distributed.

It's just amazing that no matter what kind of monster it is, their heads are headed towards the center of the oasis!

All the corpses were facing the center, as if someone had placed them on purpose!

One more peculiarity.

There are almost no wounds on these monsters, and they all look very old, giving people the feeling that they are ......

"They weren't killed, they were old enough to run over on their own, lying here and dying of old age!"

Cheng Lin suddenly opened his eyes and was amazed.

This scene was quite weird, and he was a little confused.

If that's the case, then why are they doing it? It's like some kind of ritual...... Moreover, there are so many corpses here, but they have not been eaten by the monsters outside, it is like ...... This is a public cemetery for the entire desert...... No living monster will come to infest. ”

Cheng Lin thought for a moment, but there was no idea, but another discovery made his heart thump.

In the white skeleton in the grass, there are many demon cores scattered around!

This is apparently the remnants of the dead monster after it has decomposed.

Based on his cursory observation just now, the number of demon cores precipitated in this oasis is probably in the thousands!

This means that this "public cemetery" has been around for a long time......

"The fact that no magic cores were found in the bones of monsters encountered in the desert before means that the magic cores can probably be digested, eaten by other monsters, or dissipated naturally...... If it's been here for countless years, it's probably ...... This oasis was conceived by these demon cores. ”

Cheng Lin could clearly perceive that the concentration of aura here was many times thicker than outside.

It made him breathless.

Whatever the reason, he was not prepared to give up, but only to guard against possible dangers.

Cheng Lin stretched out the wide-area vision.

He carried the "black flag" behind him, threw off the car, and stepped into the oasis on foot.

With the help of Perception, he began to search for the Demon Core above the fourth level.

A ...... Two ...... Three ......

The reserves here are surprisingly large.

"Probably only monsters above the fourth rank can survive to old age, and most of the low-level monsters were hunted and eaten before they died of old age." Cheng Lin thought to himself.

At first he was cautious, but after picking up a few dozen, he was sure that there was really no danger here.

Gradually, he went deeper and deeper.

Soon, he was in the heart of this oasis.

It's a shallow lake.

It's not big, and you can see it at a glance.

Clear, peaceful.

It is like a piece of warm jade dotted on this land, shining golden in the light of the setting sun.

It's hard to imagine that this is the source of the river.

"What's that?"

Just when Cheng Lin came to the shore and looked at this small lake, his eyes suddenly widened.

I saw that in the middle of the lake, there was a collapsed stone gate.

The stone gate seems to have existed for countless years, mottled with vicissitudes, ancient and mysterious, like a puddle of rocks, piled there, soaked in the lake water.

But it can still be seen that it should have been an extremely large portal.

"Space Door!"

Cheng Lin's heart moved, and he recognized its source.

This is the entrance for the otherworldly monsters to enter in the deduction, and after Shi Shengcun self-detonated, it finally broke through the critical line and became the door of real matter!

"It still exists?"

Cheng Lin remembers that when he released countless meteorites and ignited the Bohai Sea, the door had collapsed and sank under the sea.

But I didn't expect that after countless years, it still exists!

At this moment, he suddenly figured out something, such as why these monsters turned their heads to the center in a ritual and died quietly.

"They are species that have absorbed the blood and genes of otherworldly monsters and mutated and evolved, to some extent, they are the descendants of those otherworldly monsters, perhaps the information engraved in the genes, which makes them yearn for their hometown, and although this door collapsed, it still retains the breath of the otherworld, so under the action of this instinct, this oasis cemetery was formed."

This is a bold conjecture that is not supported by evidence.

Cheng Lin didn't know if his guess was correct or not, but this was the only explanation he could give.

And just when he stared at this "ruin" with some amazement.

West Horizon.

The sun finally sank to the horizon.

The light and heat are gone.

On the canopy, the last rays of afterglow finally disappeared.

Cheng Lin only felt that the sky and the earth were dark, and night was falling.

The next moment, he only felt a flower in front of him, and a muffled sound like coming from the sky enveloped the earth!

A vast oasis that radiates brilliance.

Everything in heaven and earth has suddenly changed!
