Beginning Backpack [Farming]

With only the shaft furnace and charcoal, Shen Huaijin can only raise the temperature to the level of forging sponge iron, which is far from enough to cast the shell of Zhentianlei.That's why he racked his brains to improve the iron smelting furnace and replaced coal as fuel.

That night.

Under the candlelight, Li held several blueprints in his hand, pointed to one of them and asked, "What is this?"

Shen Huaijin looked at where his finger was pointing.

"It's a water exhaust bellows." He explained, "Relying on hydraulic blowing tools can not only increase the amount of air output, but also reduce the consumption of manpower. It's just that the crank on the top is difficult to make. You have to ask the stone first. See if you can make it out."

Li's eyebrows raised slightly, and his fingertips slowly brushed over the crank on the paper, without saying a word.

Shen Huaijin looked at him secretly, seeing Li's heavy burden, as if he was facing an enemy, he was relieved and wanted to laugh, so he coughed twice.

"Don't worry." He comforted in a gentle voice, "It doesn't matter how much you use a double bellows, plus the improved blast furnace and coal, you can still achieve your goal."

The silver-haired orc put the blueprint aside, put his hands behind his head, his eyes were a little confused, "Jin, why didn't we use coal to make iron before, but now we need it again?"

"Before coal was not used, it was because of sulfur."

"sulfur?"

"Well." Shen Huaijin explained unhurriedly: "Although coal can achieve the ideal high-temperature smelting effect, the sulfur it contains will infiltrate into the iron during the calcination process. Iron tools are brittle and difficult to use. We don’t have the ability to desulfurize yet, but forging sponge iron is no longer a problem, so we chose charcoal at the time.”

Li suddenly realized, propped up his upper body slightly, opened his eyes wide, and spoke quickly, "But the iron shell we are going to cast now is used to hold gunpowder, and it will face the end of exploding, so it doesn't matter if it is brittle or not. !"

"You're right." Shen Huaijin's eyes showed appreciation.

"After I make paper from the bamboo mud steamed a few days ago, we'll ask Shangshi to go to the base together. It's best to live there for a few days and remodel everything we need before coming back."

As the night darkened, the voices of the conversation between the two gradually weakened. Once the candles in the room were extinguished, only the sound of breathing was left behind.

Both of them got up early the next morning, and began to pour all the bamboo mud that had been hoarded for a long time into the pool.

In part of it, Shen Huaijin also added some green water mixed with various plant juices.The two poured materials into the curtain again and again, and after the excess water flowed out of the bamboo curtain, they turned the bamboo curtain over, and the wet green paper fell on the board, and they were stacked one by one.

Even with the cover of a work shed, it is not comfortable to work for a long time in hot weather.Shen Huaijin wiped the sweat from her head, then turned around and rubbed her waist, letting out a sigh of relief.

Li was busy non-stop, his dark skin was covered with dampness, and his repeated movements were as beautiful as flowing clouds and water, which made Shen Huaijin take a look at it when he was resting.

Li was shaking the paper at this end, and Shen Huaijin also started drying the paper at the other end. Fortunately, the weather was sunny and the temperature was high, so the paper dried the fastest this time.

The two had no time to go to the base until the blue paper, white paper, hard paper, and soft paper were all dried and sorted.

After waking up early again, Shen Huaijin and Li just ate some food at random, then set off to find Shi, and talked with him for a while.

Shi looked at the drawing, and his already wrinkled face tightened even more. After rubbing his hands together for a long time, he finally opened his mouth, but his tone was very embarrassing.

"This... is not impossible, but it should take a long time, and I can't guarantee that it will be perfect."

Shen Huaijin was already very satisfied to get such an answer.His eyes lit up, and he said: "It doesn't need to be perfect, as long as it can be used. It's just..." Shen Huaijin paused, "The bellows is quite big, and it's inconvenient to move it back and forth. If it takes a long time, it will be troublesome." You stayed at the base."

Shi waved his hand casually, "It's all trivial. There is a shed at the base, and the conditions are already very good. We haven't slept anywhere before..."

Shen Huaijin and Li looked at each other, knowing that Shi was going to talk about the past again, so he quickly changed the subject.

The silver-haired orc strode forward and put his shoulder on Shi's shoulder, "Time waits for no one, let's go, let's go to the base first and then talk about it."

Shi's brows were already frowned, and he yelled on the way out as he was being led out, "I said... Li, don't pull me, I haven't taken my things yet!"

Shen Huaijin picked up the leather tool bag on the side, and said loudly: "Take it, take it!"

The two of them didn't give Shi any chance to resist, they pushed and pulled him out of the valley in one fell swoop. Shen Huaijin also greeted the returning collection team, "Ann, we're going to the base."

Shen Huaijin would chat with everyone from time to time these few days, and the sub-beasts naturally knew his intention of leaving, so they didn't ask too much, but raised their hands and waved to them, "Got it."

An Zhan stood still and said: "Jin, you should pay attention to safety over there. Those blast furnaces and bellows may not be finished for a while, and the foundation will be uncomfortable, so you can go back to the valley to rest."

Shen Huaijin said helplessly: "This bastard Ling has lived for so long, are you afraid that I won't get used to it?"

An curled her lips, "Lingpishi, it doesn't look like you."

"..." Shen Huaijin choked for a moment.

Li beside him touched the corners of his unconsciously curled lips in a funny way, "Ann, don't talk about it, Jin will lose his temper at that time."

Shen Huaijin kicked his calf, but couldn't hide the smile in his eyes, "Let's go!"

Shi picked up his tools and followed with a blank expression.

The three of them walked along the avenue, traveling very quickly, and arrived at the base not long after.Li went to negotiate with Lin about the blast furnace, while Shen Huaijin and Shi walked to the stream passing by to consider how to install the bellows.

"Let's just go here, otherwise, there is a place to build a blast furnace nearby, which is just right." Shen Huaijin stepped on the stream and suggested.

Shi didn't have any opinion on these things. He walked around twice against the sun, his eyes narrowed, "It doesn't make any difference, Jin, just listen to you."

The base has not started much work yet, and there are not many things to be busy. The orcs are scattered in twos and threes to enjoy the shade and chat, which is a bit comfortable.

Seeing this, Shi hurriedly greeted a few young orcs nearby and asked them to help chop some wood.

Seeing the orcs get up quickly and walk away, without any intention of being lazy, Shi Cai turned back with confidence, and said slowly: "No matter how difficult it is, the beginning is the most important thing. Once your hands touch the wood , No matter how complicated the structure originally seemed, it can gradually become clear."

Shen Huaijin listened to her heart and nodded deeply, "Shi, you are right. No matter how many times you say it is difficult, it is useless. Only by doing it can you succeed."

He is naturally cautious, but sometimes he becomes cautious in doing things, which becomes a burden.

If he had the mentality of a stone, then when he was making iron, he must have actively taken out the blueprint of the hydraulic bellows, and started to do it while studying, instead of retiring because he was worried that the work would be useless.

If it is done, the efficiency will be many times higher.

Seeing his frowning, Shi smiled twice, and sincerely comforted him: "Jin, your approach is also correct, but it doesn't apply to everything. I think Li's personality is a bit like mine. If you communicate more before doing things, you won’t be afraid of making mistakes.”

Shen Huaijin nodded repeatedly.

At this time, Li Yulin also came over, seeing that there was a clear expression on Rin's face.Shen Huaijin didn't say much, just exchanged a few words with him, then took out the blueprint of the blast furnace, and called the orcs nearby, and everyone gathered around to study.

"It's twists and turns, it looks really complicated." A young orc said naively, clasping his head with his fingers when he spoke, apparently really confused.

"It's okay, Jin and I will do it with everyone." Li said solemnly.

Rin next to him also looked like he had a chance to win, "Li, Jin, with your words, I must be at ease."

None of the people present were sloppy in their actions, and before they chatted a few words, their hands were already itching to start working.Shen Huaijin didn't say any more, and at an order, Shi followed him to build a hydraulic bellows, while Lin and Li worked together on iron-smelting blast furnaces.

Before the soldiers split into two groups, Shen Huaijin took a look at Li.The latter smiled at him and said in a low voice, "Don't worry, I've learned everything."

Shen Huaijin nodded slightly, and then walked away in peace.

A group of people were busy almost day and night, and based on their understanding of the shaft furnace, it was Li and his side who first researched the blast furnace, and Shen Huaijin's side finally installed the hydraulic bellows.

The two sides were gearing up and gave each other a look, "Try it?"

As soon as it was done, coal and finely crushed ore powder were thrown into the interior of the blast furnace layer by layer, and the bellows opened and closed, blowing the bright orange flame upwards.

After several days of high-temperature training in the fire, on a still hot night, the bright orange liquid finally flowed out slowly from the furnace door.

Everyone was stunned, and looked at Shen Huaijin cautiously. After receiving the affirmative look in the latter's eyes, they jumped up excitedly and exclaimed: "We succeeded, we succeeded!"

Shen Huaijin didn't join in the fun, but couldn't hide the smile on his face, he clenched his hands tightly, and his excitement was beyond words.

The silver-haired orc squeezed his face, which was somewhat dirty from soot, and took out the clay mold for casting, "Come on, try it."

"Ok!"

Shen Huaijin and Li joined hands to pour the flowing liquid into the hollow mold, let it flow freely, and then slowly mold it into the shape they wanted with a little bit of cooling.

After knocking open the mold, everyone looked out curiously, only to see that what fell on the ground were two pieces that were nearly semicircular in shape.

Shen Huaijin picked up the two semicircular iron sheets, put them together, and stroked the gap with his finger, "Then heat the two halves and connect them."

After everyone followed his instructions, Shen Huaijin pointed to a small hole left on the iron shell that was left to cool, "It's enough to put the gunpowder in here when the time comes."

After explaining, Shen Huaijin naturally couldn't wait to try it, and added gunpowder to the iron shell belly, and added a lead wire.

For safety, everyone hid behind the boulder in advance, and once the fuse was ignited, Li vigorously threw it far away.

Not long after, there was only a loud noise that shook the sky, and the smell of burning sparks wafted over immediately.

Everyone cautiously poked their heads out, and saw that the muddy ground that was hit by the thunderbolt in the distance had been blown into a hole, and the vegetation beside it was full of sparks.Taking a closer look, the iron shell has been turned into several sharp-edged fragments, which have been ruthlessly pierced into the tree and soil. It is not difficult to imagine what kind of power it is to be trapped in the flesh.

Now, Shen Huaijin finally followed suit.

"We made it."
