In the dark tree hole, a tree trunk hung upside down in the center, crackling and burning wantonly from the bottom to the top, and the dim yellow fire swayed gently, reflecting Lin Yun's sweat-stained white face red.

Lin Yun carefully put nitric acid, charcoal and sulfur into the air mixer, and with the rapid rotation of the air mixer, the three quickly turned into powder, and then quickly merged into one.

This air mixer is a high-tech product made by Lin Yun in 2195, and it has intelligence inside, with more than three million mixing and matching modes.

For example, you only need to input gunpowder and it will automatically mix according to the proportion.

The air mixer does not have a blade, and the air pressure inside it is so strong that even diamonds can be turned into powder in a matter of moments. It was also the research and development of this air mixer that made Lin Yun the strongest mechanical master in the solar system in one fell swoop.

Like gunpowder, that's the lowest kind of stirring fusion. For powerful air mixers, it can be completely automated.

After a while, the air mixer stopped, and when Lin Yun opened it, it was full of finely crushed black powder.

"Gunpowder, finally made!"

Looking at the puddle of black powder, although he had expected it, Lin Yun's eyes couldn't help but flicker with excitement.

Lin Yun was already a little overwhelmed, and he couldn't wait to see the power of gunpowder.

He gently twisted a trace of powder with his index finger and thumb, flicked his nails at the burning trunk, and a trace of powder fell on the flames of the trunk.

"Bang Bang Bang ......"

Suddenly, the originally burning flame instantly increased, and there was a crisp explosion sound, and the upside-down tree trunk that was blown up swayed.

Seeing this, Lin Yun couldn't help but be a little excited.

This powder of gunpowder is so powerful that if all the gunpowder made is burned, the explosive power will be amazing.

Even with Pan Mingxuan's bian state, Lin Yun didn't believe that he could survive the explosion!

But soon, Lin Yun's brows furrowed again.

Although gunpowder is available now, it is a little too dangerous to carry it like this. Gunpowder is a very flammable and explosive thing, if it accidentally explodes during the carrying, I am afraid that I will be the first to die.

And if you really meet Pan Mingxuan, this gunpowder is not very easy to use directly.

You can't just take the gunpowder and light it. may blow up Pan Mingxuan to death, but with his own mortal body, it is estimated that he will inevitably die.

"The best way to do this is to make a gunpowder qiang and launch it with gunpowder qiang. Immediately, Lin Yun had a more definite idea in his heart.

And he is very confident that if the gunpowder qiang is used to fold the tools in the space, the gunpowder punched by the gunpowder qiang should exert a stronger power than the direct ignition.

It's just that this idea just came out, but it was rejected by Lin Yun: "The corrosive effect of gunpowder is too strong, and it is not possible to make it with wood." If you want to perfectly exert the power of gunpowder, I am afraid that at least steel, titanium alloy and other materials with strong hardness and corrosion resistance are needed. ”

Not to mention titanium alloy, even if it is iron, it is difficult to get it in this barren mountain and wilderness.

Materials, and most importantly, materials!

He was a mechanical master, and he had an empty stomach of knowledge and ability, but he was stumped by the materials.

This is really a good woman's cooking without rice.

"Ahh

Just when Lin Yun was still worried about gunpowder, a miserable scream suddenly came from outside.

Someone's coming! And they should have fallen into their own trap.

Lin Yun suddenly shook his head, immediately put aside the distracting thoughts in his heart, took out the wooden gun from his waist, and then neatly climbed to the top of the tree trunk through the ladder in the tree hole.

From the three-meter-high trunk of the tree, Lin Yun can overlook a 100-meter radius centered on the giant tree.

Above the trunk of the tree, Lin Yun could clearly be seen ten meters away, and a man dressed in white had fallen into a trap he had dug.

It was supposed to be a pit to prevent wild beasts, but unexpectedly, a person was caught.

At this moment, he was pressing the edge of the pit with both hands, one leg up, and crawling out of the pit in an extremely comical posture.

"Holy shit, which bastard dug a hole!" he cursed as he crawled.

"The clothes he is wearing are a little similar to Pan Mingxuan's clothes, he should have wanted to kill me. ”

Lin Yunxin on the trunk of the tree said, his pupils shrank, his eyes flashed with a hint of coldness, he raised the wooden gun in his hand, and directly aimed at it with the virtual locking technique.

Burst...... Burst......

The silenced wooden gun made a low sound, followed by the extremely embarrassed screams of the man in white.

Halfway up, he fell straight into the pit again, blood flowing from his shoulders, legs, and lower abdomen, staining the dirt in the pit red in a moment.

Lin Yun cautiously took out the environmental detector from his bosom again, and swept the actual map of the surrounding two hundred meters with himself as the center.

In this cruel environment, he had to be cautious and cautious. Because of the slight half-point difference, it is very likely that you will be greeted with death.

After finding that there were no other people within two hundred meters around, Lin Yun breathed a sigh of relief, went down the stairs and walked down the big tree out of the tree hole, and walked to the pit.

"Hey!"

Lin Yun looked at the person in the pit condescendingly and drank coldly.

Lin Yun deliberately did not hit his important parts, although his shoulders, legs and other positions were extremely seriously injured, but his life was temporarily undead.

"Sure enough, it's you!" he tried to stand up after seeing Lin Yun, but he only moved his limbs, and then fell down weakly.

Maybe it was because of the excessive blood loss, or maybe it was because of the pain in his limbs, his face was pale, and he was weak even to speak.

The expression of anger and wanting to kill turned into unwilling resentment at this moment, and it looked extremely funny.

"Sure enough, it's me? Are you hired by Pan Mingxuan to kill me?" Lin Yun squatted down, took out a wooden gun and pointed it at him and asked.

As if afraid that he wouldn't answer, Lin Yun touched his nose with his left hand and said, "If you don't say it, I'll kill you now." ”

"Boy, I advise you to be obedient and captured. The man in white didn't answer, he looked at Lin Yun, his eyes suddenly widened, and he said in a threatening word.

It's just that the threatening words came out of his weak mouth, but there was no sense of domineering.

Lin Yun didn't talk nonsense with him, he directly raised the wooden gun, and with a pop, a paralyzed blood suddenly splattered from the right chest of the man in white.

"Give you one more chance, say it or not. Lin Yun pouted.

After the shot, the muscles on the white-clothed man's face twitched, he clenched his teeth, and even became slurred when he spoke: "I, I'm Pan Mingqiang, an inner disciple of the Ling Feng family, you, you provoked us, the Ling Feng family." You're going to die, it's ugly!"

Lin Yun's brows furrowed.

This person really doesn't know what to do, don't you know that Lu Dao is holding his life, and he dares to threaten himself.

"Forget it, if you want to die, I'll give you a ride. Lin Yun said lightly, raised the wooden spear and aimed directly at his head and heart.

Puff puff......

Two rhythmic gunshots rang out, blood splattered out like water, and the man twisted his neck, and he couldn't die anymore.

In this cruel environment, Lin Yun has long learned to be ruthless, especially in the face of enemies.

Since there is no valid information in the question, it will be a hundred if you kill it.

Lin Yun pulled him out of the pit, groped around with him, and found two hundred-yuan martial arts coins, some dry food, and a pair of strange things—gloves!

This pair of gloves is not an ordinary glove, but a metal glove that emits a silvery-white glow.

The glove is beautifully designed, with a weld on each finger that corresponds to the joints of the fingers. When the hand is put on this glove, it is completely possible to perform any movement such as clenching a fist.

I think it should be a prop for their martial arts cultivation.

After checking the glove, the corners of Lin Yun's mouth couldn't help but rise slightly.

If Lin Yun guessed correctly, this glove should belong to a type of steel. As for what kind of steel, Lin Yun couldn't be sure for a while without the inspection of special tools.

However, one thing is for sure, the strength of this glove is very high, but I don't know how the corrosion resistance of the road is. If you use it for gunpowder, it is definitely one of the good materials.

"The harvest was good. Lin Yun threw the gloves into the folding space, then dragged the guy up and threw him directly into the mountains.

In this barren mountain and wild place, I am afraid that in less than a day, the dead body will be dragged away by the beast, and Lin Yun will not bother to deal with it anymore.

Then, Lin Yun dug the original bloodstained pit again and covered it with fresh weeds, as if nothing had happened.

After doing everything, Lin Yun then got into the tree hole again, and not only the words of the dead Pan Mingzhi came to mind.

provoked their Ling Feng family?

By the way, it seems that after Li Xueyan saved herself last time, she was in her boudoir and vaguely heard her say that Pan Mingxuan was the inner disciple of the Ling Feng family.

That's absolutely right, it must be Pan Mingxuan who sent someone to kill him.

Lin Yun's eyes flashed with three points of fierceness.

If he kills his pet, he will kill himself, and he will not be able to hide in this place.

And he took his mecha, and he must take it back again.

It seems that the enmity with Pan Mingxuan is endless

By the light of the fire, Lin Yun saw the sealed gunpowder.

Gunpowder is one of his important magic weapons to deal with Pan Mingxuan, but now there is a lack of gunpowder qiang, otherwise, now Lin Yun dares to carry a gun and directly kill back to Sun City and snatch back his own mecha.

Thinking of gunpowder qiang, Lin Yun remembered the metal glove he had just snatched from that guy.

Lin Yun couldn't wait to take out the metal gloves in the folding space, and then took out the detector again and began to test the metal gloves.

He had to test the hardness and corrosion resistance of metal gloves to determine whether they could be made into gunpowder.

This detector is also a high-tech in 2200, which can detect hundreds of accurate data such as hardness, corrosion resistance, heat resistance, melting point, etc., and the test data has no peak value.

For example, the hardness of the diamond found on the earth is 1,000 on the detector, the hardness of prism found in the solar system is 5,000, and the hardness of the mecha made by Lin Yun that can travel through time and space is 200,000!

"Hardness twenty-four, corrosion resistance thirteen, heat resistance eighteen. ”

The metal gloves are placed in the detector, and the detector quickly gives a row of accurate data.

"If I'm not mistaken, it takes at least fifteen to resist gunpowder. The hardness and heat resistance are enough, but the corrosion resistance is still a little worse. Lin Yun's brows furrowed.

If you use materials with poor corrosion resistance to make gunpowder, you are afraid that you will have to scrap it after firing a shot, and if you are more serious, you may explode before you shoot, but you will harm yourself.

Hardness, corrosion resistance and heat resistance must be met!

"I can only wait a little longer, I hope that someone will come over again, if I can get something more resistant, I can make it into gunpowder!" For a while, Lin Yun hoped that someone would come over and kill him.
