It's a pity that the amount of soil nitrate is too small now.

At the current pace of these catalytic crates, it would take at least a week to make a full crate of black powder.

Li Yan frowned slightly, "We still need to domesticate some creatures that specialize in and expand the scale of the catalytic house!" ”

In his mind, the ancient shovel-toothed elephant flashed in an instant.

This fat and strong herbivore creature is best at the "lazy trifecta", that is, eating, pulling, and sleeping!

Thereupon.

In addition to hunting upgrades, he plans to include the domestication of "specialists" in his important survival plan.

Finished trying gunpowder.

Li Yan finished eating the food as soon as possible, and then took the dinosaur team and continued to move towards the west.

After yesterday's disturbance by the megalodon, it is certain that the ancient giant jellyfish will no longer gather in the shallow waters.

Without jellyfish, and he can't solve the oxygen problem, he can't hunt other creatures in the sea.

Therefore, these last more than 800 points of energy still have to find a way from the depths of the jungle.

Along.

Li Yan rode a big bull and ran on the mountain with "vigorous".

A level 8 heavy horned beast can crush the creatures on the outskirts of the jungle almost at will, and it was not until he reached the top of the mountain that he asked the big bull to slow down and be careful.

He hadn't forgotten that when he was looking for a water source before, he had seen an extremely ferocious ancient giant spider here.

"Squeak——!

At this time, above the sky, a level 14 yellow-brown pterosaur flew again.

He looked at the toothless pterosaur that was more than four meters long and shook his head and sighed.

I don't know when I will be able to domesticate flying creatures, so that is called real high mobility!

Climb over the hillside.

Li Yan passed through the valley and the cave all the way, and came to the plain where he had hunted the ancient shovel-toothed elephant and domesticated the heavyhorn beast.

Unlike the steppes of the earth.

There are occasional large bamboo forests and tall bushes, which are not unobstructed.

And at this very time.

Suddenly, in the distance to the northeast, there was a loud trembling sound, and it was no exaggeration to say that it was as if the mountains were really shaking:

Knock ——!

Knock ——!

It's footsteps!

Li Yan could hear that such a regular rhythm was definitely the sound of a large creature walking around.

And the creature that can make such a loud footstep sound......

Thinking of this, he hurriedly raised his head.

The next moment.

In the far northeast, about forty or fifty meters away from him, he saw a huge neck, slowly rising from the bushes.

One-meter, three-meter, five-meter......

It's more than seven meters tall!

It has a huge body, green skin, a small head, a long neck and tail, at least nearly 20 meters long, more than 40 tons, of which, the neck alone accounts for as much as half, after straightening, it looks like a crane.

Mamenxi Dragon (Level 19)!

"This is a super giant-level creature!"

Li Yan looked up at this huge Mamenxi Dragon, compared to the other party's mountain-like body, he couldn't even compare to the big bull, and even one of its legs!

This kind of creature, it is estimated that even the Tyrannosaurus rex is very difficult to help!

If he could domesticate the Mamenxi Dragon, wouldn't he be able to build a mobile camp on its huge back!

In this way, you don't have to think about moving at all in the future, it's completely a mobile battlefield fortress!

It's so convenient!

And.

With such a large size, Mamenxi Dragon can break a lot of tree trunks with a casual sweep of its tail, and it is definitely a super weapon for collecting wood and plant materials!

It's a pity.

With Li Yan's current ability, he can't deal with such a huge super creature at all, and at most he can only lust in his heart.

Then, he hurriedly asked the big bull to bypass the Mamenxi dragon.

Although this stupid big man is a docile herbivore, no one can be sure of his true temper.

Next.

The surrounding bushes and grasslands, one by one, passed by him, and occasionally, Li Yan could see a lake, and some triceratops were standing next to the lake, drinking water leisurely.

He found that there were too many large herbivores in the area.

But it's also normal.

The terrain is relatively flat, with abundant vegetation and grassland, and a stable source of lake water.

It's simply a perfect haven for herbivores.

No wonder he encountered the herd of ancient shovel-toothed elephants and the herd of heavy horned beasts twice.

This time.

Suddenly, there was a loud running sound ahead.

Stampede Tread......

Stomp ......

Li Yan frowned slightly, and hurriedly took out the binoculars.

I saw a small gentle slope ahead, several huge yellow-green creatures were rushing down the slope, rushing towards this side, among them, there were huge triceratops, and there were also some small herbivorous dinosaurs.

"What's the situation, the earthquake?"

Just when he was puzzled.

Suddenly, behind this group of herbivores, there was a huge dinosaur that was seven meters long and more than two meters high!

The reason why it attracted Li Yan's attention so much was because this guy actually had a thick layer of brown-red hard armor all over his body, and on top of these hard armors, there were all kinds of sharp and thick white spikes!

Ankylosaurus (level 16)!

Like Triceratops, one of the most famous dinosaurs of the Dinosaur Era!

This guy is very close to the image in film and television works.

Even more exaggerated.

Its whole is like a small shield dragon that has been magnified several times, but the spikes on its back armor are much larger than those of the small shield dragon.

In particular, the two sides of the rib armor and the two spikes on the middle line of the back are particularly terrifying, almost catching up with the sharp horns of the triceratops!

And the most terrifying.

It's a huge bony hammer the size of a watermelon at its tail!

On top of the hard hammer, there are also many spikes, especially on the sides of the hammer body, the two sharp corners like half of the knife, flicking back and forth in the run.

There is no doubt about it.

Once it is stained by this hard hammer, it is a blood hole!

"It's so handsome, it's just a fully armed armored tank!"

Li Yan looked at this ankylosaurus, and then looked at the turtle immortals around him, comparing the two, he suddenly felt that his family's Wang Ba was a few points weaker!

But.

Under his careful observation, this awesome ankylosaurus seemed to be as frightened and panicked as those fleeing herbivorous dinosaurs.

The next moment.

"Roaring ——!"

With a huge roar, on the gentle slope, a huge dinosaur suddenly pounced, opened its bloody mouth, and bit down on the neck of the ankylosaurus!

Boom knock!

With tremendous force, the ankylosaurus fell to the ground at once, and a large amount of dirt and wild grass were splashed out.

With a roar.

Two behemoths just rolled down the gentle slope like this!
