Island Survival for All: I entered one year in advance

Chapter 47



While everyone was busy, it was getting dark, and it was 7 p.m.

"Let's take a break, let's eat first!" Chen Yi walked out of the villa and shouted at everyone.

After hearing the call, several people put down their work, returned to the villa, sat down at the dining table and began to eat.

On the weekend, he was the first to report the results: "The charcoal is put into the kiln and fired, and it is estimated that it will be baked in almost 2 hours!"

"I made a big bucket of sulfuric acid for Ijie and them, it should be enough!" Yu Kun continued.

"Phew~, it is indeed enough, but it is so difficult to extract potassium nitrate, we extracted it several times, and only collected about 100g in total!" Yijie said with a disappointed look.

"It's okay, it's almost enough! In the future, the way to obtain it is still to find saltpeter ore! Seeing this, Weekend comforted.

"Now it's just that the charcoal hasn't been made yet! We just have to wait for the charcoal to burn and we can prepare to make gunpowder! Weekend said excitedly.

Soon, everyone finished eating, sat in the living room and chatted, waiting for the last material, the charcoal to be made!

Although the hot version has passed, not everyone can search for enough water every day. So 30,000 pieces of well water were put on the shelves on time over the weekend, and it will slowly sell out after dozens of minutes.

"Let's eat some watermelon~" From the kitchen came the lively voice of the afterwarbler!

I saw Yu Yingying and Chen Yi coming out of the kitchen with a large pot of watermelon.

"Hey, hey! Fruit after meal, late but arrived! Zejun quickly picked up a piece of watermelon and said with a smile.

"Wow! How can there still be watermelon to eat! This is also too happy! Yu Kun froze in shock when he saw the watermelon again, and today he was numbed by shock.

Zhihao looked at Zejun and Yijie, who were eating wildly, speechlessly, picked up a piece of watermelon and handed it to Yu Kun, who was in a daze, and said: "You can eat it quickly!" I'm going to be eaten by the two of them later! "

Ugh!"

"Oh! Good good!

Yu Kun recovered from his daze, quickly took the watermelon handed over by Zhihao and began to eat it.

......

In the small talk of everyone, the time quickly arrived at 9 pm.

"The charcoal should be burned, let's take it out and see!" Weekend said to Zejun.

"Okay! Let's go! Zejun replied.

The two got up and walked to the makeshift charcoal kiln.

On the weekend, I opened the kiln mouth, took out the burnt charcoal from the inside with an iron clamp, and saw that the appearance was black and gray with the help of the light, and I felt light and fluttery in my hand.

"Hmm! The roast was quite successful, and it looks like the quality is not bad! Yu Kun, who came out after him, looked at the piece of charcoal and nodded and said.

After hearing this, Weekend smiled and said to Yu Kun: "That's good!" I'll clip out the pieces inside for you, and I'll listen to your arrangement next!

"Okay! I need everyone's help to grind these raw materials into fine powder, and then we can start dispensing gunpowder!

"Okay! Then according to the previous distribution, everyone grinds the materials they make into a fine powder! Weekend nodded, and then said to everyone.

There were not many materials, and it took everyone less than half an hour to complete the task and hand over the ground powder to Yu Kun!

"I heard that the recipe for making gunpowder is 'one nitro, two yellow, three charcoal', is it just a 1:2:3 ratio mixed?" Zejun saw that Yu Kun was configuring gunpowder and asked curiously.

"Haha, you misunderstood this!' 'One nitro' refers to one pound of potassium nitrate in the gunpowder configuration, while 'two yellow' refers to two taels of sulfur, and the last 'three charcoals' is three taels of charcoal! Yu Kun explained.

Zejun suddenly realized and continued to ask: "Oh~ So the real ratio is 10:2:3, right?

Yu Kun smiled and continued to explain, "Haha! Still not right, an ancient pound is 16 taels! Zejun

smiled awkwardly when he heard this, and said without dying: "Ah! The real ratio is 16:2:3! You can't go wrong this time!

Yu Kun nodded, and then continued: "This time I didn't say anything wrong! This is how black powder was prepared in ancient times! However, according to later modern scientific research, the optimal ratio should be 15:2:3!

Σ(っ °Д °;)っ

Zejun smiled awkwardly but politely and did not speak again.

......

Fortunately, this awkward atmosphere did not last long.

Ten minutes later,

"Finally configured!" Yu Kun raised his head and said happily.

Immediately afterwards, Yu Kun put the configured gunpowder into a jar and handed it to the weekend.

Weekend took the gunpowder, walked with everyone to the basement floor of the villa, and then took out the S-class stamping machine that had not yet been used.

S-class stamping machine:

a fully automatic press used by external power supply, the user only needs to provide the specific parameters of raw materials and models to automatically generate molds, and realize fully automatic production.

After seeing the use requirements on the weekend, he looked confused and asked several people: "Wait!" Who knows the specific parameters of the bullet used in this gun?

"Ah this... We don't know! Everyone shook their heads when they heard this.

"Why don't you ask the 'gun god' who designed the manuscript for you! He knows for sure! Yu Kun reminded on the side.

"Okay! I'll go and ask him! Weekend nodded and replied.

So over the weekend, he edited a message and sent it to 'Gun God':

"Hello! What are the specific parameters of the bullet used in the pistol on the design manuscript you gave earlier? "

About three minutes later, the 'gun god' sent a reply

: "Bullet data

: caliber: 9mm Bullet length: 25mm Full bullet mass: 9.6g Warhead diameter: 9.04mm Warhead

mass: 6.15g Cartridge case Maximum diameter: 9.45mm Cartridge

case length: 17.2mm

Propellant charge: 0.22g

"

After receiving the news over the weekend, I immediately entered the parameters given by the 'Gun God' on the equipment parameter panel of the S-class stamping machine, and then placed the finished gunpowder at the material entrance.

"Drip! After parameter calculations, the current amount of gunpowder can finally produce 605 target bullets!

Current lack of material: copper (5.68kg). "

After seeing the prompt over the weekend, I took out the copper smelted by today's mining truck from my backpack and put it into the material mouth of the stamping machine.

[Start processing] then the button changed from red to green, and there was no hesitation to choose to start directly on weekends.

Immediately afterwards, I saw the central control screen of the stamping machine display

: current status: complete materials, processing!

Production speed: 300 rounds / min;

Current progress: 0/605.

As the stamping machine began to operate, the progress began to skyrocket.

While happily waiting for the production of bullets on the weekend, the 'gun god' sent another private message:

"Big guy! I recently sorted out the design parameters of the AK47 automatic rifle, I only need you to provide me with a blank manuscript, I can sort it out in three days, and provide you with the complete AK47 automatic rifle design manuscript like last time, do you need it?

"What? AK-47! Weekend couldn't help but exclaim.

Everyone: o_O?
