When Li Yan came, he deliberately hunted a level 5 creature, and then decomposed a level 4 fragment, a level 3 fragment, and two level 1 fragments.

The process of domestication, except for one of the level 5 spars, which failed once and wasted a level 1 origin spar fragment, the rest were all one-time successes and formed them into a "squad".

It was noon.

He leisurely led the three stupid "elephants" back to the camp.

After lunch.

Li Yan was not idle, took the materials from the warehouse, and came to the open space in the camp, ready to start building a special shed for the team.

To know.

If an elephant concentrates on pooping, the amount of food and excretion is very alarming, and it is difficult to control.

Similar to the previous method of digging pits, it will definitely not work.

Moreover, he usually goes out to hunt, collect supplies, or return to Earth to build "logistics", and he has no time to manage these guys, and it is impossible for him to go to the woods to pick up everywhere.

So.

In order to scientifically and conveniently allow the team to quickly accumulate a large amount of feces, it is necessary to build a centralized factory for them to eat and.

The first thing Li Yan thought of was the breeding shed!

It is a shed similar to the ancient horse feed, so that the horses stay in the shed, and in front of them, there is a feeding trough, which can be eaten by bowing their heads.

So.

Horses can feed and excrete at the same time in the barn, and the position is concentrated.

But because Li Yan needs a lot of feces.

Even if all of them are concentrated in the shed, it is not easy to collect, not only easy to be trampled on by the ancient shovel tooth elephant, but also easy to get covered in the body, causing infectious diseases.

So.

He came up with an improved way to build a ditch in the wooden shed like an old-fashioned public toilet and a groove for collective squatting!

The specific operation is to put a long wooden box without a lid in front of the shed and use it as a trough.

The front half of the shed is made into a high platform for standing or resting, and the back half, that is, the bottom of the buttocks, leaves a blank space, and a row of wooden boxes are placed at the bottom, in which a small amount of dirt and decaying organic matter are placed.

So.

The ancient shovel-toothed elephant can be eaten while taking two steps back to excrete its feces precisely in a wooden box that is empty.

When the time comes.

As long as Li Yan regularly pumps out the wooden box, he doesn't need to pick up manure, and stirs it directly, which is a ready-made soil nitrate catalytic box!

"666, it's a shame, I've developed an automated assembly line!"

He laughed at himself and immediately began to use the carpentry table to break down the planks and build a shed.

Although the feces of herbivores do not smell great.

But Li Yan still didn't want to sleep by himself, and the house was full of the smell of.

So, he built the shed at the farthest north end from the rest area, the same wall next to the camp gate.

So long.

He has also built quite a few sheds and has already had experience. The height of the high platform is set at half a meter, which can fit the box in the back, and it is also a lot more convenient when it is extracted and installed.

And with the squad, the catalytic room also needs to be expanded.

Because of the limited space in the camp and the boxes that catalyze decaying organic matter, the smell is greater.

So, he was going to set up the catalytic chamber outside the camp.

Anyway, no creature will come to steal and destroy this thing, right?

It's too late to hide!

It can also play a role in driving away!

When all the equipment for the soil nitrate assembly line was completed, it was already about three o'clock in the afternoon.

So far.

Li Yan arranged for pangolins, buns, and buou, to collect rare plants every morning, and in the afternoon, to fill the trough of the breeding shed with all kinds of fresh plant forage.

The team, on the other hand, must fill all the catalytic boxes in the shed every day before they can move freely out of the shed.

Anyway, there are three large wooden boxes in total, three ancient shovel-toothed elephants, one like one, and it is estimated that it will not take one morning to pull them all.

That's how it goes.

Three new boxes of earth nitrate catalytic boxes are added in a day, and the earth nitrate reaction is complete, it will take about three days, and at that time, you will probably get three to four copies of the earth nitrate required by the alchemy unit.

The manure fertility of one catalytic tank is about enough to react for two cycles.

Then, if Li Yan wants to make a whole box of black powder, it will take more than a week in the early stage, and in the later stage, the catalytic box will accumulate more and more, and it only takes four to five days for him to save a box!

Obedient boom!

Save resources like this, let alone blow up dinosaurs.

Hoard for half a year, and I can even blow up the mountains!

Really!

Holding on to the development is the ultimate royal road!

Li Yan was happy, and immediately returned to the house, lying on the wooden bed and resting leisurely.

Evening.

He took Chief and Ergouzi and went to the valley where the water level was deeper to the west, and caught two fish with raw meat.

That's right.

With the stone pot, of course he had to try the fish soup.

And this time, Li Yan discovered a new species: the first arowana!

This guy has a blue body and looks a lot like a modern-day Arowana.

In fact.

The Arowana itself is indeed an ancient fish with a very long history.

Maybe it's because the water environment is too small, or maybe it's because there are too many natural enemies in the stream, such as bantams, ancient man-eating pomfrets, etc., so this archaeoptera is only about half a meter, and it is obviously still underage.

After all, the Arowana on the earth have grown to half a meter, and the fish are all lifelong growth, the oxygen content of the prehistoric world is so high, and there is no human influence, destruction, and the body size will naturally evolve to be larger.

But it doesn't matter.

For Li Yan, the half-meter-long fish is enough for him to eat several meals!

And now he has just upgraded the dimensional space, and he is also "wealthy", and he is too lazy to decompose it, so he threw it directly into the space, ready to go back to the scales, and stew the bones together, which is even more delicious!

Putting aside the dangers of the prehistoric world, with all kinds of restrictions aside.

If you really bring all kinds of modern equipment, spices, etc., to Dinosaur Island, it is really a very enjoyable thing.

Just like the Arowana he caught tonight, on the earth, the color is good-looking, and the small fry of more than ten centimeters are all fried to tens of thousands.

And here, half a meter long, dozens of catties of Arowana, you can eat it casually.

Li Yan stewed for a long time, opened the lid and smelled it.

Ooh!

It's so fresh!

It is several times fresher and more beautiful than the ancient man-eating pomfret pomfret!

This is the life he pursues, and the main reason why he is so desperate to level up.

When his strength becomes stronger, Li Yan will no longer have to worry about this prehistoric world, and the entire Dinosaur Island will be like a back garden, allowing him to play casually.

When the time comes.

If you do encounter a native tribe.

Usually teach them the culture of the earth.,Teasing the primitive girl.。

Out of the tribe, he rode the Tyrannosaurus rex to hunt in the jungle, rode the pterosaur to the sky, and rode the dragon to play in the sea.
