In the early morning, the cold wind on the cold Xinjiang Plateau was swishing, so Yu Xian got out of the tent wrapped in a jacket and warmed up with a shovel first.

After eating some breakfast, Yu Xian returned to the entrance of the cemetery to make sure that the safety rope had not been bitten by the new monster, and then began a new day of fossil search.

After two days, the regular fields near the camp were rummaged through, and no clues were found, and the new signers still pointed to the rift valleys.

"It's a zone of geological change..."

Lying on the cliff, Yu Xian looked at the bottom of the valley.

Compared with the surrounding terrain, the rift valley must have been torn apart after the formation of the cold plateau, so that the dinosaur fossils buried deep in the mountains were exposed, which led to the frequent popping up of pointing markers on the edge of the rift valley.

You have to go down to the bottom to know how it is.

The center of the rift is more than 600 meters deep, and the climb up and down plus the search is a huge amount of work.

Considering that it is not easy to go on a trip, it is not a problem to bring enough water bottles and food to stay for a day or two.

The pterosaur's claws, combined with the ability to climb ornithischia, quickly descended against the mountain wind.

When approaching the valley, click on the dragon map and the ancient map, and the four pointing signs beat at the same time, and the strong perception impacts the brain, and the scalp is slightly numb.

This is still the result of the reduction in the supply of soul power, which can be seen in the fossil order of the valley.

Maybe it can be compared with the underground karst cave of the Lianchi Mountains.

Yu Xian secretly made a judgment in his heart, and jumped to the bottom of the valley to look at the rocks nearby.

The fossil was buried shallowly, without the need for a shovel, and a hooked mouth was revealed under the rubble.

Psittacosaurus, 21% fossil integrity

It is a fairly common dinosaur in the Hanjiang Plateau and nearby areas, one or two meters in size, and the fossils are distributed in many countries, from juvenile to adult, one of the dinosaurs with the largest number of Cretaceous fossils.

What Yu Xian currently dug up was a fossilized skull of a psittacosaurus dragon, there was nothing to delve into, so he took it back and sold it for money.

Place the Psittacosaurus next to it first, then look at the next pointer.

This time, the fossil is buried relatively deep, and the arrow pointing vertically downward after reaching the destination is not solid, and the beating frequency is also low, indicating that the distance is quite far.

Remove the rubble, revealing a five-metre-square rock slab.

Summon a feathered tyrannosaurus, bite the rock, and exert his body and soul power to lift the entire rock slab, revealing the sand layer below.

After using a folding shovel for a long time, digging more than three meters into the ground, the pointing mark was stuck on the fossil.

"What is this?"

The fossil looks like the horn of a legendary unicorn, poking out of the hole.

Thinking that this was an ancient atlas, not an object found in the dragon hunting atlas, Yu Xian quickly guessed the answer.

Cornerstone of the house!

Closer to the fossils, the ancient atlas gives the same conclusion.

Cornerstone with 83% fossil integrity

The shape of this thing resembles a chili fried snail, the kind of conical and threaded field snail.

It's just that the cornerstone is very strong, and it is the apex predator of the ocean in the Ordovician period 400 million years ago, and the length can reach 9 meters!

9 meters of snail, what is the concept?

Tyrannosaurus rex is in its early 14 meters, if it is a cornerstone...

[The world is so big, there are no wonders]

"! I shouldn't have given this bad example! They are hundreds of millions of years apart! ”

[Friends, do you know? 】

[The world is so big, there are no wonders]

[Friends, do you know? 】

"Huh?!"

In Yu Xian's mind, the opening remarks of the two identical marketing accounts were played in the order of half a second before and after.

Encountering this situation for the first time, Yu Xian didn't dare to be distracted.

It is difficult to complete the editing in such a short time difference, and there is only one grid of materials, so you must work hard and weigh the weight.

[There is a monster disguised as a human in the world, which is usually exactly the same as a human being, but it is actually a monster]

[In places where the yin qi is very heavy, in special circumstances, you will occasionally see ancient soldiers passing by in a procession]

The different content is echoed in the idle brain, in fact, the amount of information is not large, and the trouble is that there is a lot of nonsense in the marketing account.

The second content is just a yin soldier borrowing the way, and he talks a lot about it.

Running two nonsense messages at the same time and many lengths, unspecific messages, is really hard to handle.

And the two entries that Yu Xianqian had can't be edited.

USB flash drive, sharp blade

Changing to a USB flash drive disguised as a human being, or a USB flash drive in the underworld, seems to be even more terrifying, and even threatens data security.

The blade is also a truth, the underworld soldier borrowed the way to change to the underworld soldier blade to borrow the way, and the danger factor has not changed much.

I don't have time to think about it for leisure, the news of the Yin Soldier borrowing is relatively brief, and the last to come is already inviting the Yin Soldier friends in the comment area.

Judgment must be made!

Compared to youkai disguised as humans, the danger of Yin soldiers borrowing the way is lower.

After all, only barren mountains and mountains, places with heavy yin qi have conditions, and that place must have a historical war background, otherwise how can there be a yin soldier.

Sealing the demons that disguise human beings, the Yin soldiers take advantage of the natural reality.

Quiet...

In the rift, Yu Xian was vigilant around him, and quickly unguarded again.

The marketing account sends a message that there is no danger in the vicinity, but there must be something related to it that has been exposed before or since.

"Isn't this a collection of dinosaur fossils? How could it be related to the Yin Soldier borrowing the way? ”

All Yu Xian could think of was the tomb hidden in the belly of the mountain.

There was an accident before, and he couldn't follow Bai Mo into the cemetery, but Yu Xian didn't go too far, and now he went down the cliff to the bottom of the valley, maybe closer to the depths of the cemetery.

It is estimated that there will be unforeseen strange changes.

Let's look at the content of the marketing account sealed in the material grid...

"Why do you have an extra material grid?!"

The mind swept across the system interface, and the material grid changed from one to two, one of which was printed with the content of the marketing account just now, and the second one was empty.

In response to the occasion when he once got the material grid, Yu Xian quickly understood the rules.

The message of the devil frog appears individually, and the system gives a material grid;

This time, the two marketing account messages appeared at the same time, and the material grid was expanded to two.

So...

"Next time the third material is expanded, won't the grid have to have three messages at the same time?"

Having said that, it didn't put too much pressure on Yu Xian.

When the three messages come, the player has two material slots in his hand, and he just lets go of one, which is similar to choosing one of the two.

However, there is a prerequisite for obtaining the grid: the content of the marketing account that is released must not lead to a catastrophic event

For example, what strange paleontology affects the development of vertebrates...

After sorting out his thoughts, Yu Xian breathed a sigh of relief and checked the news sealed by the grid.

There are actually two aspects to it.

One is that there are monsters disguised as humans in the world;

The second is that only those who have double eyes can see through the disguise.

Quite a classic urban legend, all kinds of weird stories about the eyes of the eyes.

But... The type is actually similar to the yin and yang eyes, and if it is unsealed, it will be unsealed, and there seems to be nothing wrong with it, after all, there are already resentful spirits and the like in the world.

When he retracted his attention, Yu Xian found that the sky was rather gloomy.

It was only two o'clock in the afternoon, and it was as dark as a cloudy sunset.

The cold wind blowing in the rift valley is not only cold, but also has an eerie aura, which always makes people feel that some kind of mysterious monster is about to awaken at the bottom of the valley.
