After a while, Li Yan grilled the meat and shared it with everyone one by one.

Now, he's almost ready to roast the meat.

What grilled fish, grilled elephant meat, grilled rat meat, grilled turtle meat, and grilled dinosaur meat, and then it is bacon slices rolled with clover green pear fruit roasted together.

If he hadn't been able to go back to Earth every seven days to change his taste, he would have vomited a long time ago.

Therefore, at this time, he hopes that the sweet potatoes will ripen soon.

Finish replenishing energy.

Li Yan began to make a wooden box out of wooden boards, and then went outside and poured the dung pulled by the dinosaur team in the past few days, plus the rhizomes and leaves of some plants, into the box and stirred.

You know, charcoal can be burned out of wood, and sulfur can also be refined from sulfur ore.

But it's hard to find.

Generally, the soil nitrate formed in nature is the potassium nitrate mixture generated by a large amount of organic matter under the action of nitrifying bacteria at the root of the wall of the old building, next to the circle of livestock, or near the toilet.

However, it was impossible for the prehistoric world to have such things as old houses and toilets.

Therefore, if Li Yan wants to obtain soil nitrate, he can only use the feces of domesticated organisms, as well as the mixed reaction of plants and trees.

Once he had it done, he left the reaction box at the door of the cabin.

As long as this method can be successful, he plans to domesticate a few herbivores to be responsible for, such as ancient shovel-toothed elephants, dodos and other lazy foodies, and then make a large number of soil nitrate reactors in batches.

In this way, he will be able to synthesize a large amount of black powder!

It's afternoon.

Li Yan removed the small beast saddle from Buu's body and placed it on the turtle immortal.

There was no way, Buu was injured, and the only one left to ride was the Turtle Immortal.

Although this guy is very slow, at the very least, he is still faster than Li Yan himself.

Of course, it's not going anywhere faster.

Therefore, because of the greatly reduced mobility and the fact that there were more things to do in the afternoon, he could only brave the hot sun, take the dinosaur team, and Fei Er, who was responsible for leading the way in the cave, and set off early.

I have to say.

I'm used to riding bipedal dinosaurs, and I suddenly changed to Dawang Ba, which is really uncomfortable.

This guy from the turtle immortal is completely in a hurry, and his body is shaking!

That feeling is like a car that is used to driving a six-cylinder engine, and suddenly changed to a single-cylinder diesel tractor, which almost broke Li Yan's ass.

However, its back armor was full of huge tower thorns, and Li Yan didn't dare to use his legs to clamp them.

"A good car is so important!"

He wanted to cry and muttered without tears.

About an hour passed.

Li Yan used the telescope to finally find a fifth-level creature next to the valley, which was the bantam dragon he had killed before: the newt.

This guy moves slowly and is not agile.

There is no doubt that under the siege of the turtle immortal, Ah Chief, and Ergouzi, he was successfully killed without his help.

Once you've got a level 5 shard, all that's left is to find sulfur ore, and tame mounts.

Due to the proximity of the entrance to the cave.

Li Yan chose to look for ore first.

After making a torch out of oil, he let Fei Er lead the way and hurriedly drilled into the hole**.

As soon as he entered the cave, he immediately felt a lot cooler.

Although the previous horned gopher has been driven away, two ancient centipede insects have also been killed.

But after all, I didn't come for two or three days.

No one knows if any other creatures have run into this place during this time.

Therefore, Li Yan asked the dinosaur team to cheer up and be careful.

Under the leadership of Hiji.

They walked hundreds of meters, turned seven or eight turns, and finally came to the pungent smell of the mine that this guy had said before.

Li Yan smelled it, huh!

It stinks!

It should be sulfur, I learned chemistry in junior high school, and it has a special smell.

Fortunately, sulfur is harmless to humans and animals.

He didn't bother to straighten his mask, and after jamming the torch outside, he walked straight inside.

As soon as you enter the mine.

Li Yan saw that on the rock wall on the right, there were many yellow and gray mixed stones.

He used alchemy to break down a piece the size of a fingernail, rubbed it vigorously, and luckily, it was really a sulfide mine!

Thereupon.

He forced Hiji to come in and dig ore with him.

The hardness of this thing is far worse than that of iron ore, and after ten minutes, one person and one rat have made more than a cubic meter of sulfide ore, all of which are packed into the alchemy soul stone.

The alchemy soul stone has ten cubic meters of dimensional space, and it is basically installed casually.

Finished with sulfide ore.

Li Yan returned to the location where he had encountered the ancient centipede insect before, and dug up a cubic meter of iron ore.

By the time he came out of the cave, the sun had already set more than half in the west, and the jungle was orange and dimly lit.

"It's already so late......"

He frowned slightly.

It seems that without Buu, the efficiency of going out to search has plummeted, because most of the time is basically wasted on the road.

Li Yan originally wanted to find a new mount, but now it seems that time is running out.

In case the mount is not found, it gets dark, and you are trapped in the depths of the jungle, it will be too dangerous.

It's safer.

So, he turned on the back armor of the turtle fairy and ordered the dinosaur team to go home.

When we arrived at the campsite, the sun was gone.

And in the jungle in the distance, the running and roaring of all kinds of beasts stubble after stubble.

It is enough to prove that Li Yan's decision is still correct.

Although the mount didn't get it.

But the level 5 shard is already in hand.

He went into the storeroom, poured all the stones that the four fat rats had dug up these days, and then prepared all kinds of materials such as iron ore, wood, flint, etc.

The next moment, he stuck to the pile, and his mind moved.

It is clearly felt.

The molecules of these substances immediately began to decompose, and then began to rearrange at a rapid pace according to the composition formula of the alchemical blueprint.

There was a delay of about a dozen seconds.

The blue light faded away, and the original pile of stones was gone, replaced by a huge stone refining furnace about 1.5 meters long, wide and high.

Interestingly.

The lower part of this refining furnace is a cube, and the upper part is a semicircular roof with a small circular chimney on the back of the roof of the furnace.

As for the top of the stove, there is a movable lid that is used to put the substances that need to be refined.

Similarly, there is a protruding notch under the front of the furnace body, which is used to cast the burning substance.

The material and the combustible material are separated by a stone partition with holes, and the division of labor is clear.

As for the bottom of the furnace, there was a blue spar inlaid with it, which was the level 5 fragment, and a circular six-pointed star array was also depicted inside, which was responsible for controlling the refining temperature in the furnace.
