The late autumn morning has already made people feel a little cool, Lu Ya stood outside the house only to feel the cool air from his neckline, and couldn't help but tighten his clothes again, at this time a thin layer of fog fell around the tribe, and the surroundings seemed a little hazy.

"It's winter soon, food is no longer a problem, the wooden houses should all be rested, huh~~" Lu Ya, who was talking to himself, exhaled lightly and turned into a burst of white mist and gradually drifted away.

At this time, the tribe has already sounded the sound of 'clanging' iron, since the old man knew how to strike iron, what is called 100 steel, every morning when the sky is slightly bright, he got up and began to strike iron, studying various methods that he thought could also improve the quality of steel.

When Lu Ya came to the earthen blast furnace, a small grass shed had been erected next to the blast furnace at this moment, and several slaves under the grass shed were working together.

The old man was not in the grass hut, but was waiting for the iron to be drawn by the blast furnace, and from time to time the corner of his eyes glanced at the converter waiting for air drying, not knowing what he was thinking.

"Uncle Tie, it's early" Lu Ya asked the name of the old man Tie, but the old man didn't seem to remember it himself, so he asked Lu Ya to call him Uncle Tie directly.

"Oh, here it is, this is the last bit of iron ore," the old man looked back, dropped the words, and continued to stare at the blast furnace without saying a word.

"Uh, I'll think of a way, this, those inferior iron tools from before can be reheated. I think the converter will be almost ready for use tomorrow, and when the time comes, Uncle Tie, you will prepare some scrap iron materials first, and we will strive for a success," Lu Ya said behind the old man.

"What do you mean by trying to succeed once, didn't you say that it would definitely work," the old man suddenly turned his head and glared at Ruya.

"Ahem~ This success is a step-by-step experiment, how can there be any 100% success, and sometimes it is possible to remember that things are slightly deviated, even then we can avoid a lot of detours, you say no" Lu Ya hurriedly explained to the old man.

"Yes. If you're reasonable, come, you're telling me about oxygen and combustion, I still don't quite understand."

"Oh, then I'll tell you again, this oxygen is a ・・・・・・ in the air we breathe" Since Lu Ya inadvertently said the previous terms on the earth such as insufficient oxygen injection for combustion a few days ago, he was heard by the sensitive iron old man, and he had to ask to understand, he couldn't stand his stickiness, so Lu Ya simply popularized the basic knowledge of physics and chemistry to him, but Lu Ya himself was also a half-asser with only a high school level, and he was a 'top student' who had never passed science before, so what he could talk about was also very limited.

However, the old man's love for these physics and chemistry really made Lu Ya a little unbearable, and he also liked to practice, the beast that was thrown into the lime and burned in the past few days was ignored by several catties, and even the little vinegar that Lu Ya brought back from the market was most of the disaster by the old man with alkali.

Finally escaped from the old man's hands, Lu Ya rubbed his nose with palpitations. "There's a bit of a mad scientist, but I'm also a half-ass, otherwise I might have asked him to come up with something. ”

After coming out of the 'blacksmith shop', Lu Ya first went to see the injured clansmen, the strong system of the orc clan once again shocked Lu Ya, at this moment except for a few clansmen who injured their legs, everyone else was already able to walk on the ground, Lu Ya even saw two wounded people carrying water between their arms on the road.

"Aunt Kama, you don't try to persuade them, in case the wound is cracking or infecting," Ruya said to Aunt Kama, who was cleaning the room.

"Hehe, no, little Ruya, they all have rough skin and thick flesh, and the delicious and delicious white rice and meat these days have long since recovered almost, so you don't have to worry about it," Aunt Kama replied with a smile.

"Alas~ It's better to be careful, by the way, all the meat has been eaten," Lu Ya asked again.

"Well, there are a few poultry left, we really don't want to kill them, we can lay a lot of eggs when we keep them," Kama said with a satisfied expression.

"Don't worry about the distressed Aunt Kama, now the injured people need adequate nutrition to recover, you can't save it at this time, let's kill them all tonight, I'll go buy some later," Ruya insisted.

"This..."

"Okay, Aunt Kama, it's decided, you want to leave me a chicken leg at night, hehe, I love to eat your roast chicken"

"Well, well, Auntie knows, our tribe now has Xiao Luya, you are really the favor of the beast god, you yourself have to pay attention to your body, it is the time to grow your body, and your aunt will leave all the chicken legs for you at night" Kama looked at Ruya's slightly immature cheeks and showed a loving smile.

"Then thank you Aunt Kama, I'll go first" Ruya didn't refuse, he knew his current position in the tribe, but it was also a responsibility.

Back in his wooden house, Ruya looked at the 3 AK47s and a large bag of bullets standing by the wall, found a large cloth bag, packed it in one go, and then picked up a body armor from the bed that looked different from the previous and went out, on the flat ground outside the tribe, Lu Ya found Bai Lifu who was leading a group of young people to exercise, walked to him and handed him the bag.

"Uncle Berry, these are 3 AK47s and hundreds of bullets, you can look at it and divide it, this AK47 rifle is the same as a pistol, there can only be 10 of them, you can just look at how to distribute them. Also, you try this body armor again and see how it works" After handing the bag to Berry, Luya took out the dark green body armor from inside.

"Okay, with this firepower, I believe that no small tribe can gnaw us now, hey~ This body armor is a little different" Bai Lifu looked at the new body armor in Luya's hand and said with some surprise.

"Well, this is my new body armor that can only be sacrificed after promotion, you can try it and see how it works. "This body armor is Lu Ya after the promotion with a high-grade stone skin spell sacrifice, the previous body armor is a compressed silk type of body armor, is considered the ancestor of the early body armor, although it can have a certain bulletproof effect, but the effect is limited after all, Lu Ya has tested, 50 meters away AK47 bullets easily shot through the silk body armor, and it is worn both front and back. This time, this kind of body armor Ruya feels that it should belong to the body armor lined with steel plates in terms of feel and weight. Imagine that the bulletproof effect is definitely much better than that of silk body armor, but the specific extent to what extent still needs to be further experimented.

"Bang!" A familiar revolver sounded, and then a sound of steel impact sounded, and the smoke cleared, and everyone who came up only found that a small pit appeared on the surface of this new type of body armor, and the small pit was only very shallow, and a trace of metallic color could be seen from the inside.

"Bang bang bang ~" was shot in the same position several times in a row, and it was not until the sixth bullet that it penetrated the body armor.

"This new body armor is too strong" The crowd of onlookers couldn't help but gasp, they all had used pistols, and they all understood the power of this weapon, this kind of body armor that can defend against multiple pistol shots in the same position seems to them to be god-level equipment.

"Try it again with the AK47," Ruya continued.

"Da~" A 7.62mm AK47 rifle bullet hit the center of the body armor, and Lu Ya saw that the place where the bullet was shot was almost coming out from the opposite side, but the steel body armor that had not been penetrated was secretly nodded.

"Well, Uncle Brick, what do you think of this body armor?" asked Ruya.

"Very good, and that would allow ten more fighters to wear body armor," Cliff said after a moment's thought

"Well, Uncle Cliff, I'm going to make all this kind of body armor as soon as possible in the next few days. ”
