The more he thought about it, the more excited Li Yan became.

If he finds a gold mine, he can mine infinitely when he reaches the alchemy level in the future, or if he domesticates a bunch of ankylosaurs.

What kind of awesome equipment can be synthesized with gold, let's not talk about it for now.

If he can take the gold to the earth and sell it for money, then he can go to the military company to buy a large number of advanced arms, which is faster than selling recipes to make money!

After all, an armored vehicle can easily cost hundreds of thousands or millions of dollars.

When the time comes, when the authority is improved and the armored vehicles and tanks are transported to the prehistoric world, I don't believe that I will not be able to dominate the entire Dinosaur Island?

Before we reached the cave.

Li Yan has already begun to be lustful in his heart, and there are quite a few Wang Dazhui routines of "becoming the CEO, marrying Bai Fumei, and walking to the pinnacle of life".

Five or six minutes later.

At his urging, Buu finally ran to the creek.

With the dinosaur squad drinking water, he went to the nearby jungle and used alchemy to break down some thatch and sticks.

Then he took out a piece of animal skin, used the fiber, wrapped the thatch on the top of the stick, and then used flint to "click" the wild grass, and rubbed it for a while.

That's right.

Li Yan is igniting a fire.

Not to mention that he had watched a lot of Xu Ye's "Wilderness Challenge" videos before, even if he hadn't seen it, ordinary people should have some common sense, and the cave can't be messed in!

Some caves may contain a lot of dust, mold, and even toxic gases, and when inhaled in large quantities, it may cause serious lung infection, and even coma and death!

Make a torch not only to illuminate, but also to serve as a warning.

Because most of the time, in a semi-enclosed space where these gases are abundant, the torch either suddenly burns very violently, or suddenly becomes smaller or extinguished.

Since the system only unlocks the fire, it does not unlock the torch.

Therefore, Li Yan could only use simple materials to assemble a temporary torch.

The sticks are used as the main supports, the thatch is used as the fledging velvet, and the hides are used as wrappers on the one hand, and on the other hand, when the flame burns, the grease in the hides is baked out and penetrates into the thatch and sticks.

With the addition of grease, thatch and sticks will become more flame resistant, and oil lamps take advantage of this principle.

It was a few minutes of tinkering.

After figuring the torches, Li Yan began to urge the dinosaur team to leave.

Don't say it, being tall is good.

He rode on Buu's body, and without getting wet at all, he crossed the stream.

Go uphill to the edge of the hole.

Before Li Yan could enter, he felt a cool wind blowing towards him.

He sniffed it twice, and when he sniffed it, there was indeed an indescribable strange smell, and that feeling was like the smell of burning hair.

But when Li Yan tried to walk in, there was nothing unusual about the torches, and he walked in with a little relief.

The area of the entire cave is very large.

The width and height are more than 10 meters, so "big" creatures such as Buu and Turtle Immortals can easily walk in.

And the size of ten meters basically limits the fact that there are not too many creatures in it.

The size of the environment directly affects the growth of organisms, which is known to all biologicals.

It's like a fish tank can never raise a big shark.

But despite this, Li Yan still let the guy Turtle Immortal walk in the forefront, who made this grandson grow so safe!

And he rode Buu, walking in second place, followed by the two dogs, Little Green, and Little Skin.

Stop.

As soon as I walked into the cave, it immediately became much cooler.

Perhaps because of the humidity of the air and the low temperature here, a lot of condensation droplets have accumulated on the rock wall and the roof of the cave, and from time to time, a few drops of water will drip down from above, making a "pop" and "pop" sound.

The further you go in, the less light there is at the entrance of the cave.

About a few dozen meters into it, with the rugged turn of the cave, gradually, the torch in Li Yan's hand became the main source of lighting.

The orange firelight reflected on the rock walls of the surrounding ravines, and then reflected through the water droplets, dragging the shadows of the dinosaur team to the ground.

"Stepping on ......"

The cave was terrifyingly quiet, except for the sound of water droplets, the footsteps of Li Yan and them walking.

"I guessed right, this cave is quite big!"

Li Yan muttered to himself, and he also felt that this cave was constantly descending.

Although the slope is not huge.

But he still saw the direction of the cave from the flow of water droplets on the rock wall.

This makes sense.

After all, the top of this cave is a hillside.

If the trend of the cave is constantly upward, then it is estimated that after a few heavy rains, or a few giant beasts more than ten meters long, the hillside will collapse.

With the current momentum.

If the cave continues downward, you might find some rare veins!

"It seems that Lao Tzu has a chance to become a gold miner!"

Li Yan grinned.

And just when he was proud, suddenly, there was a "squeak" sound in the cave.

That feeling, it doesn't look like a mouse, and of course it can't be a mouse, rodents themselves evolved very late, and modern creatures like rats are even more unlikely to appear!

"Is it a bug?"

Li Yan suddenly thought of the trilobites he had encountered before, and arthropods liked to stay in such a dark and damp place.

"Squeak...... Click! ”

It's the same strange sound again.

He frowned slightly, and hurriedly took out the wooden shield from the dimensional space.

There was no way, the dinosaur couldn't hold a torch, and light was very important, so he could only have one free hand.

The most important thing is to save your life first.

So Li Yan took out the wooden shield, and then warned the turtle immortals to be cautious.

The next moment.

When he turned into the next corner, the scene in front of him couldn't help but make him stunned!

I saw that a huge empty clearing, densely packed around, full of all kinds of caves, all kinds of caves, some big and some small, looked like an overpass extending in all directions!

And this time.

Two "squeaks" were heard from one of the caves.

Immediately after, a dark shadow emerged.

Against the backdrop of the firelight, Li Yan saw that the creature was about 1.5 meters long, because in the orange firelight, he couldn't see exactly what color it was, only that it was a dark color.

Its appearance resembles an enlarged hamster, and its body is very fat, but judging from its sharp front teeth and sharp front paws like a knife, it is much more ferocious than a wild hamster!

And the most special thing is that on its head, there are two huge sharp horns that curve upward!

Yes!

Li Yan repeatedly confirmed that he was not mistaken!

The rodent in front of him resembled a mouse, just like a triceratops, with sharp horns on the top of its head!
