The newly excavated cemetery has a rotten and old atmosphere, worse than this underground cave.

In this way, these caves should be connected to the outside world, otherwise the air is not in such a good state.

Caves deep underground are more or less waterlogged in some places, or underground water veins.

Find a place where there is a water source to solve the life support problem first, and then follow the water source to try to find the location of the groundwater coming out of the surface.

Without the help of others, Yu Xian could only tentatively set the plan to this part.

Before going deeper underground, extract the bloodline power of the spiny ankylosaurus.

Click on the icon to drop a 51% fossil intact spiny ankylosaurus into the app like a player.

The progress bar popped up, and Yu Xian watched it deduct while paying attention to the changes in his body.

When extracting the power of the ankylosaurus, Yu Xian didn't grow a carapace, so don't suddenly grow spikes...

There was a burst of tingling from the wound, and the cracked flesh quickly scabbed over at a visible rate and protruded into more resilient body tissues.

Yu Xian clenched his fist slightly, feeling good.

While strengthening the body, it will promote the healing of wounds and necrotic parts, and the bruises on the legs will also melt away a lot, leaving a faint blue color.

After taking stock of the existing supplies, Yu Xian's backpack was almost intact, and it was only smashed as a cushion when it fell.

The compressed biscuits inside were a little broken, and the canned food was a little deflated, which did not affect the consumption.

Everything else is fine, but the phone is broken in two because of the hard impact with a hard object, and it can't be used.

"Mobile-machine-"

Carrying his backpack, Yu Xian estimated that the things stored in the backpack were enough for a week, and the drinking water would last for two days at most.

For insurance reasons, Yu Xian first went down to the depths of the cave to make sure that the follow-up route was not too obstructed, and then returned to the place where the stone collapsed.

"The pangolin brother inside, although we didn't know each other before, but we fought together, and we are good brothers, and now I am short of supplies here, and it's useless for you to keep your backpack, support the little brother."

A few stones were removed, followed by a clattering collapse, and the sound of rolling stones echoed back and forth in the cave.

Yu Xian confirmed the path behind in advance, and did not worry about these rolling sand and gravel blocking the road, but the action had to be lighter, and if he was not careful, the sediment on the top would collapse again.

Digging out the pangolin's backpack, Yu Xian thanked him again and retreated to the depths of the cave to count the supplies.

The backpack of the Bai family pangolin also has compressed biscuits, some dried fruits and supplements for vitamin supplements.

The situation is similar to just now, there is no big problem with the food, and the key is the water source.

A new source of water must be found within three days.

Yu Xian, who has yin and yang eyes, does not need any lighting equipment, and loses all the flashlights and batteries that add extra weight.

I don't have a smokeless stove anymore, and I don't have such a good condition to set up a pot to cook things, so I only bring a small packet of flint and steel and a portable lunch box, and I have to boil it to collect it when I find a water source.

Then it's time to unseal the material grid and free up the storage space.

In case of danger underground, the marketing account suddenly began to behave again, so that there was a material grid as a buffer.

Now the material grid is sealed with an ankylosaurus to hit the Tyrannosaurus rex with internal injuries, which can be edited.

Yu Xian currently has entries: Lost, Animal

The word "animal" comes from the black witchcraft news, they used animals to extract bloodline power, and as a result, they were replaced by Yu Xian for a USB flash drive.

Now, replace "Tyrannosaurus rex" with the word "animal".

A large sledgehammer on the tail of an ankylosaurus can cause internal injuries in animals.

There's nothing wrong with it, it can indeed inflict internal injuries on some animals, as long as the size or something loses to the ankylosaurus.

Unblock the marketing account, free up the material grid, and start to explore deeper caves in your spare time.

Bang, bang

Lonely footsteps echo in the darkness, silence all around, endless stretches of rocks, and the forces of nature are colder than ghosts hitting walls, and it is inevitable that people will panic.

This panic is not a direct threat to life when facing monsters and mechanisms, but the brain can't help but think:

If you can't get out of the darkness and can't get out of the darkness, and the shouts and signals can't be transmitted to the outside world, then... Starting from falling into the deep darkness, has Yu Xian's "existence" been erased from the world?

Thinking about it, Yu Xian's mind was not thinking about these philosophical questions at all, but:

Shouldn't the protagonist fall into the cave be given a peerless magic + grandfather package?!

You're talking to a street fighting system!

Yu Xian's heart was disgusted, and his feet did not stop.

In the past, the altitude of the cemetery was average, and if you fall a few hundred meters down the inside of the shop, it is estimated that the altitude is about the same as the bottom of the mountain.

Usually the mountain is cone-shaped, and the lower it goes, the larger it is, and the less easy it is to dig out of the middle;

The advantage is that the further down the mountain, the more groundwater veins converge, and the easier it is to find a breakthrough.

These two conditions are reasonable, it depends on luck, and it is better to be unlucky to encounter better conditions.

With the same cave rocks under his feet and the endless darkness in front of him, Yu Xian could only urge himself to go diagonally downward.

Even if the current line selection may be wrong, it cannot be stopped.

With the exhaustion of the spirit, the soul power was reduced to less than thirty percent, Yu Xian took out a tarp to wrap his body and rested in a relatively flat place.

Before going to bed, click on the Dragon Hunt Atlas.

The marketing account system is unreliable, and it is often as quiet as a chicken at a critical juncture, and it still has to rely on the power that has been taken out of the system.

Even if you can't move fossils out deep underground, using the dragon hunting map to find more fossils and extract more dinosaur bloodline power can always increase the probability of survival.

Sleep, wake up, continue to act in the same darkness until exhausted, go back to sleep, wake up again...

Counting the pangolin's backpack, Yu Xian estimated that the drinking water could last for three days, but after walking for so long, the concept of time was completely lost, and he didn't know if the consumption and the expected time were compatible.

In such an environment, the ammunition is gradually exhausted, and as long as the will is not firm at all, I am afraid that the nerves will have already collapsed.

Boom...

"Huh?!"

There was a crisp sound from the depths of the ground, and Yu Xian's somewhat numb nerves woke up.

Stop, slow down, and listen.

It's the sound of water!

Although it sounded far away and the sound was hazy, it was enough to tell that it was the cooing sound of the water hitting the cover.

"Whew, survived."

Only those who have a water source can at least solve the problem of life maintenance, and only those who survive are qualified to find a way out.

The opening of the cave in front of him gradually narrowed, and Yu Xian was quite nervous in his heart, but he was blocked by the rock formation only three or five meters away from the groundwater.

After so many days of bad luck, I didn't continue to be unlucky.

The ground in front of him came to an abrupt halt, and Yu Xian leaned out half of his body to find that there was a larger cavern outside.

About five meters below, an underground river flows slowly.

Throw the backpack to the bottom, and jump out of the branch passage directly.

After crawling and rolling in the harsh environment, Yu Xian has gradually become familiar with the strengthened body, which is nothing.

Smack-

The water splashed everywhere, and Yu Xian picked up the groundwater and slapped it on his face, feeling fresh and breathable, and the dead wood was spring.

A wipe of the cheeks, in addition to the water droplets, there are a few soft little things, black, squirming in the palm.

"Leech !!"
