Beginning Backpack [Farming]

The returning market team was surrounded by people, and Shen Huaijin couldn't leave for a while, so he patiently and slowly blew up the glass column in his hand, then cut it open and spread it on the iron plate, pressing it hard flat.

Not surprisingly, it was another piece of clear glass.

He put the tools in place, and kneaded the tiger's mouth where the airbag was pinched sour, then slowly got up, intending to go to Yan.

Coincidentally, the other party also came to look for him, so Shen Huaijin invited Yan to sit on the stone chair in front of the house for a while.

"Yan, is the road going well? Why did you come back so early this time?" Shen Huaijin poured a large bowl of scented tea for him, and took the lead in greeting after sitting down.

It takes more time to go to the cross-origin market. Logically speaking, the team will have to wait until the off-season at least before returning, but there is still a short period of time before the off-season.

"It was right to choose to travel with the Dasen Tribe. After the orcs of the two teams got together, basically no wild beasts dared to invade us. In addition, we set off early this time, and we didn't stay too long after we got there. , so I came back earlier than before.”

While explaining, Yan looked at the near-completed east wing, his serious face couldn't hide his surprise, "Jin, how did you come up with this method of building the house? It looks better than our thatched cottage. It is stronger and more windproof. Hey, but why do you have so many big holes in the wall, so you can’t die of cold in the cold season?”

"I also learned this from other places." Shen Huaijin casually made a haha ​​to perfunctory, and when he heard his last question, he explained dumbfoundingly: "Those places are not holes, I specially vacated them to install the glass. Where the windows are."

"So that's the case." Yan nodded thoughtfully. He had already learned some knowledge about "glass" from the twittering of the people in the tribe just now, so he didn't ask any more questions. "After the city wall is built, the orcs in the tribe have to work harder, so that everyone can live in such a house in the future."

"Of course." Shen Huaijin agreed with a smile. After he gained experience, he would be able to guide everyone to build a brick house together. At that time, there would be no need for the sub-beasts to warm each other pitifully to survive the cold season.

"By the way." Shen Huaijin's face was full of expectation, she blinked her eyes, eagerly hoping to hear some good news, "Yan, what good things did you get when you went back to Shihuoyuan to go to the market?"

Yan shook his head helplessly, "The tribe that Shihuoyuan is in charge of opening the market is not big and can't accept many teams, so most of the tribes that go to the market will leave after a few days. The same is true for us. Except that we bought a lot of salt at the market , I don't see a single thing you wrote on the paper."

Shen Huaijin's look of anticipation disappeared, even though she had already made such preparations, she was still frustrated, "That can't be helped, let's talk about it later."

"But..." Yan smiled slightly, and even left Shen Huaijin in suspense, "We passed a mountain on the way back, and there was a saltpeter-like existence in the mountain. We couldn't tell if it was true, but we thought what if it was true. You will definitely want it, so I carried a lot of it back.”

This is a turn of events!

"What?!" Shen Huaijin stood up in surprise, "Yan, take me to see it!"

"follow me."

Yan led the way and introduced the origin, "We found these saltpeter-looking stones in a cave on the way back. We were all resting at that time. When Qi saw it, he thought it was salt and called us all excitedly. I got up and tried it before I realized I was wrong."

"I thought at the time that the saltpeter in the tribe was mistaken for salt by everyone at the very beginning, so maybe the ones in the cave are also." Yan said that he felt that his guess was too random, and he was afraid that Shen Huaijin would look at it. Afterwards, I found out that I was even more disappointed, so I had to smile a little embarrassedly, "Jin, I'm really not sure if it's saltpeter, so don't get too excited."

Shen Huaijin clearly understood his concerns, and smiled slightly, "I know."

The two hurried to the other side of the stream, and all the materials exchanged from the market were piled up on the square, among which were seven baskets of saltpeter-like things in Duoyankou.

Shen Huaijin lifted the animal skin covering it, picked up a heavy piece and looked at it carefully, and experimented with water.

This stone-like mineral is not white like the saltpeter Shen Huaijin is using because it contains many impurities. The edges of the massive minerals are light red and mottled by the accumulation of wind and sand.

However, the characteristics are consistent with saltpeter. After repeated several times, he asserted: "Yan, your guess is correct, this is saltpeter! You really helped me a lot."

"Really?!" Qi, who hadn't left yet, stood aside and curiously joined the discussion, "We didn't believe what the leader said at the time, after all, the saltpeter you used were all white ones, how could it be like this one? It looked big and dirty. But Yan insisted on carrying it back for you to see, so we piled up all the salt we exchanged, and vacated the rattan basket to hold the stone."

Shen Huaijin clenched the block of saltpeter in his hand, his nose felt a little sore, "Yan, Qi, thank you."

Seeing his red-rimmed eyes, Qi teased: "Jin, we came back from carrying this thing so hard to make you laugh, why are you crying instead? You can't let Li see it, or you will chase after the challenge Me, I can't handle it with my old bones."

Yan glanced at him, and said in a deep voice: "Jin wants the saltpeter for the benefit of the tribe, it has nothing to do with personal preferences, don't talk nonsense."

Seeing Qi's devastated look, the deep emotions that had haunted Shen Huaijin's heart disappeared, "I didn't intend to cry."

"That's good." Qi said quickly, "Otherwise Li will think I'm bullying you when he sees it. If he chases me and challenges me, I won't be able to handle it with my old bones."

"Who do you want to bully?" A calm voice came from behind Qi.

Qi turned his head, only to see a tall silver-haired orc standing behind him against the light, his face was expressionless, which made him yell out "Aww" in fright.

"Severe!" He howled, "However you walk without making any sound, you startled me."

"It's not that you talked too hard yourself so you didn't notice me."

Shen Huaijin couldn't help but burst out laughing.

After Qi saw it, he patted his firm belly in relief, "Smile, okay, you little Asian beasts are frowning all day long thinking so much. What are you doing? Let the older ones come first, you all Just give me responsibility and be happy."

Yan coldly kicked Qi, "Shut up. Follow me to Taniguchi to build the city wall." He nodded to Shen Huaijin and Li as farewell, then dragged Qi who was addicted to talking and started talking endlessly, and left .

Shen Huaijin watched them leave, then let out a long breath, and looked at Li, "An explosive surprise is coming."

One sulfur, two nitrates, and three charcoals are the proportions that modern people are almost familiar with. It took Shen Huaijin nearly three years to collect all three raw materials for making black powder.Of course, this shows the relationship between the quantity of substances. When converted to quality, the ratio of sulfur, potassium nitrate, and charcoal is basically 2:15:3.

Shen Huaijin first crushed each raw material into powder, and then made a simple balance with uniform thin iron rods, separated the various raw materials with the same quality standards, and then mixed them together in proportion.

"Is that all right?"

Li thought it was just a preparation beforehand, but when Shen Huaijin mixed the raw material powder, wrapped it in paper and put it aside, he asked strangely, as if in a fog.

"En." Shen Huaijin nodded, "If it's just for mining, it's enough. If you want to use it to resist something, you'd better add an iron shell to it. We'll talk about that later."

He kept moving, soaking the slender hemp rope in saturated potassium nitrate solution, taking it out after making sure it was soaked, and putting it aside to dry.

Shen Huaijin explained: "Once the black powder is ignited, it will burn violently, and at the same time, a large amount of gas will be generated in an instant, resulting in a sudden increase in pressure, and then an explosion will occur. It is as if we keep filling the bag with water and eventually the bag will be destroyed. Like a burst, the gunpowder accelerated the process to an instant."

Li listened half-understood, and followed Shen Huaijin's instructions to dissolve and recrystallize the nitrate brought back by the market team, while continuing to ask: "Jin, what are you drying the rope for?"

"Is that so? This is used as a fuse. After igniting one end, let it burn slowly to the other end and then ignite the fuse. The time in the middle allows us to run away to avoid being injured."

"Is the power of gunpowder so powerful?" Li looked at the three different powders that were ordinary and combined with Shen Huaijin's description, he was a little unbelievable.

Shen Huaijin smiled and showed her sharp canine teeth, and her bright eyes were full of confidence, "You will know when the time comes."

Because there is still a large amount of nitrate waiting to be recrystallized, Shen Huaijin only made a small part of black powder, and planned to take it to the base to test the water first.

The orcs stationed at the base were very happy to see them, and when they heard that Shen Huaijin came to the mine to test something called "black powder", they were all very positive.

Shen Huaijin said to the manager of the base: "Rin, Ming, I'm not sure about the effect and scope of the gunpowder explosion. For safety's sake, everyone should try to stay as far away as possible."

"No problem." The two orcs said in unison.

Although everyone was curious, they still followed Shen Huaijin obediently and withdrew 300 meters away.

Li poured a large bag of gunpowder into the gap between the ore, hooked up the fuse, and quickly evacuated back to Shen Huaijin after lighting the other end of the fuse.

The orcs have keen ears and can hear the slow burning sound of the lead wire. Everyone held their breath and waited quietly for the moment when the lead wire ignited the fuse.

Under the scorching sun, a thin layer of sweat appeared on Shen Huaijin's forehead, and he waited anxiously, fearing that he would not succeed.

Just when everyone was a little bit guilty in their hearts, they heard a loud bang, and the ground seemed to shake. Accompanied by a thunderous explosion, the ore rolled down, and the scene also billowed with thick smoke.

"It really exploded! It really exploded!" The orcs were pleasantly surprised, and a few young and bold ones wanted to rush up to observe carefully, but were stopped by Shen Huaijin.

It wasn't until the smoke dissipated that Shen Huaijin led everyone back to the mine, only to see large and small ore rolling on the ground, and there was still a pungent smell left by the explosion.

"This... this..." Ming was dumbfounded, "Jin, Li, do you still have this gunpowder? Can you use it for mining?"

"Don't worry, the current amount is not enough, and I decided to allocate a part of it for mining."

Ming said with emotion: "In the past, we had to spend a lot of effort to heat the ore before mining, and then poured cold water over and over again. Double! Jin, this is really a good thing!"

Shen Huaijin nodded, with a reserved tone, "That's good."
