Like a swarm of swarms disturbed in its sleep, a large number of slippery mollusks wriggled on the ground, in the water, and behind the rocks, the scale of which was comparable to another black stream of water.

Leeches are blood-sucking animals, and there are few animals in the deep and dark underground, so it is difficult for Yu Xian to understand how so many leeches reproduce.

But now is not the time to think about the evolution of species, run away!

The swarm of leeches behind him is extremely abnormal, crawling quite fast, and even some of the larger individuals can be ejected by twisting their bodies.

Yu Xian's body has been strengthened by the power of dinosaur blood, but he has not directly grown armor on the surface of his body, and if he gives two more bites to the leech, he will always be bitten through the skin and suck blood.

Being chased like this, I couldn't run deeper into the cave as originally planned.

The more leeches were hoarded along the current, Yu Xian could only run against the direction of the current to the top of the slope on the shore.

There are black mollusks constantly jumping out of the water, which makes people look at it and make it sick to their stomachs.

As the area of the passage narrowed, Yu Xian was getting closer to the rising area of the underground river, and there was less room for maneuvering.

A few leeches jumped on their trouser legs and were quickly kicked away, and it was okay to deal with it in the short term, and it was not a way to go on like this.

Raising his head, Yu Xian saw that there was a cave fork that opened inward about twenty meters above the rock wall, and immediately reached out to grab the rock wall and climbed up with a smoke.

This climbing proficiency is far beyond the range of leeches' ability, and the bare hands climb the rock to move through the clouds and water, without the slightest stagnation, and directly throw off the crisis below.

"Whew."

Until the upper hole that the leech could not reach, Yu Xian breathed a sigh of relief.

It is worthy of the instinct absorbed from the family of birds that are good at climbing, and the climbing ability is beyond imagination.

With such a distance, Yu Xian had free time to observe the situation of the entire dark river below.

The river poured in from farther away, forming a waterfall at the height of the drop, in which a filamentous substance fluttered, like seaweed.

Nori is not present in freshwater, and is presumably the root system of other algae or plants.

In places where the water flow is slightly shallow and slower, leeches can be seen clinging to the plant roots and eating vegetarian, forming a similar symbiotic relationship.

When a living creature approaches a potential threat to plant extension, a swarm of leeches will attack.

In contrast, the decay and dissolution of leeches after death also become nutrients for the root system.

Seeing such a scene, Yu Xian suddenly lost the motivation to go down to fetch water and drink.

Even if the leech swarm doesn't attack, all kinds of disgusting things in the water will make people can't eat it.

I can only change my original thoughts, go up with the water, find a clean place at the source, and don't make the next plan.

Before continuing to climb, Yu Xian glanced at the underground dark river again.

If you are trapped in the belly of the mountain for too long and the food in your backpack is exhausted, do you want to eat leeches...

Vomiting ————

"No, no, this won't work."

In the eyes of ancient medical scholars, leeches are actually a medicinal herb, especially the leeches here do not absorb any blood, most of them are sucking the juice of plants, which sounds relatively clean.

But... Physiologically, I really can't accept it, unless I starve Yu Xian half to death, I will never have the idea of playing leech packages.

Looking into the depths of the current cavern, there was only an arm-thick hole in it, and it was impossible to continue walking, so it had to climb higher.

Although Yu Xian has gained some of the crawling instincts of the bird dragon family, and there has been obvious progress in quality, he has not fully adapted to the height, and is more or less afraid of heights.

Forcing himself not to look down, Yu Xian climbed all the way to the level of the underground river's gushing outlet, and then jumped into the hole.

Be vigilant and observe the current, there are also black mollusks wriggling inside, just because Yu Xian did not rush to the surface of the water to disturb this time, and the leech swarm is temporarily stable.

There is still no rest, so I can only continue to swim against the current to find a clean place to get water.

Keep a distance from the dark river, act until the remaining thirty percent of the soul power rests, and then continue to trace the source.

As he walked, Yu Xian gradually realized that something was wrong.

There are fewer and fewer leeches in the dark river, and they are probably washed down, but the long strips like plant roots are still there.

What kind of plant can grow so long at the root?

Climbing up another section of the cave, Yu Xian estimated that he had gone down the slope a few days ago, and had climbed back to a similar height these days.

Because of this, leeches are almost invisible in the current.

Pick up a large rock and throw it, the water surface breaks the waves, and then resumes normal flow, nothing unusual.

Yu Xian was relieved to scoop water in the lunch box, and then use flint and steel to ignite some rotten branches that were washed ashore.

While the water was boiling, Yu Xian tried to pick up a plant root from the dark river, and found that this thing really continued from a high place to the abyss.

The jungle knife that had been picked up was put down again.

I was going to cut off the roots of the tree to see what the situation was, but Yu Xian thought of the symbiotic relationship between the leech and this strange plant, and temporarily dispelled the idea of harming the plant.

The water is boiled first, and the amount of water stored in the kettle is increased.

It's not easy to find comblamibles underground, so Yu Xian continues to expand the scope of exploration, and the decaying branches and leaves he has gathered are only enough to boil a pot of water.

Something is better than nothing, and after so many days of going down to the ground, you can finally drink hot.

"What kind of sin am I doing, I have to touch the pangolin business at every turn."

Thinking back to the peaceful days in the city, assuming that Yu Xian hadn't made such a trip, it would be more or less time to receive some of the editors' contacts now.

The dozens of essences of the five essay collections "Xueba Library" sent out in the follow-up should have nothing to change, and most of the editors' contacts are through review, and then a stamped inclusion letter will be sent to Yu Xian.

Thinking of the beautiful life outside, Yu Xian ignited his fighting spirit, and he wanted to go out no matter what!

Drink some hot water and get some sleep to recharge.

The marketing account is as quiet as a chicken, and Yu Xian can only rely on his own strength.

Before you go, click on the Dragon Hunt Atlas to see if there are any dinosaur fossils nearby that can be extracted.

Just inadvertently confirmed the use of the Dragon Hunting Atlas, and it seemed that a huge stream of information exploded in Yu Xian's mind.

After resting, the soul power that recovered to almost full capacity exploded, and instantly fell from 100% to less than 50%.

The huge mental loss made Yu Xian's body shake, and he almost fainted, and now he was drained by a pumping machine in an instant, and his brain froze for a long time before he eased up.

"What's the situation..."

The mental impact was too exaggerated, and Yu Xian didn't know whether his trance had passed for a few minutes or dozens of minutes, but what he could determine was that there were layers of superimposed pointing signs beating in front of him.

With that click just now, the dragon hunting atlas found a large number of dinosaur fossils in one go.

Each dragon hunt requires additional expenditure of the player's mental power, and the consumption is huge in an instant when it is multiplied.

Leaning on the rock mass, Yu Xian gently sat back on the ground, easing the residual dizziness and concussion in his brain.

The signs of the dragon atlas just now indicate that there are a surprising number of dinosaur fossils in the vicinity...
