People in Mondstadt, starting to develop black technology

"We are here to escort these wounded back." Paimon flew to Klee and high-fived her.

Ying came in front of Shen Qin and said, "We also accepted the commission from the Adventurer's Association, but we didn't go to the frontal battlefield. We were only responsible for clearing out the clustered monsters and doing some logistical work."

"Yes, in just these few days, we have earned a lot of Mora!" Paimon said excitedly.

"Paimon, we're not doing this for Mora." Ying looked at her with half-closed eyes.

"Oh! I know, we mainly want to contribute to the protection of Mondstadt." Paimon smiled, "And earn some Mora to buy delicious food!"

Keli clapped her hands very politely: "Awesome! Keli also wanted to go out of the city to blow up the bad guys, but Captain Qin asked me to stay with Brother Shen Qin to protect him. Keli thought about it and felt that protecting him was more important!"

Shen Qin smiled and touched her head.

"It's safer for little Keri to stay in the city. The battle on the front is too brutal..."

Before Paimon could finish his words, Ying pulled him away. She smiled and said to them, "We haven't eaten anything today and we are starving. Let's go to the Deer Hunter to eat first. See you next time!"

Wow, I made a lot of money. I even had Mora to go hunting deer.

"Today, Sister Ying is even more greedy than little Paimon! In the past, it was always little Paimon who dragged her to eat!" Keli secretly told Shen Qin about her discovery.

"Yeah, just like I am sometimes more playful than Klee." Shen Qin said with a smile.

Jean didn't let Klee join the war because the war was too dangerous and too scary. After all, in terms of her mental age, she was still just a child and shouldn't be involved in such things.

So Qin found a reason to put her next to Shen Qin. After all, he would only be active in the safe rear area, thus preventing her from witnessing the cruelty of the battlefield with her own eyes.

"Nonsense, Klee is not into playing around!"

"Haha~"

Keli looked at Shen Qin's right arm, her eyes rolled, and she suddenly jumped up, hanging on his hand: "You bullied Keli, as punishment, you have to be Keli's swing!"

At night, Keli fell into a deep sleep in the guest room, while Shen Qin tossed and turned in bed, unable to fall asleep. He thought of those men who went to the battlefield with high spirits, and also of the bodies that were transported back from the front lines.

"System, let's draw a lottery and see if there is anything that can change the current situation." He used up his last chance for a random draw.

The system's lottery ended quickly, but looking at what he had drawn, Shen Qin was a little amused, because what he had drawn was something that could easily change the form of war in Teyvat - the principle and technical implementation of explosive bomb weapons.

Hello! System, this is the world of Genshin Impact, not the world of Warhammer 40k!

That’s right, what he drew was the bolter weapon used as the main weapon by the Space Marines in Warhammer 40k.

Unlike traditional gunpowder weapons, which use the thrust generated by the explosion of gunpowder in the cartridge case to push the bullet out, the kinetic energy of the bullet will continue to decay after it leaves the barrel.

Explosive weapons are based on gunpowder weapons, but simply integrate a power propulsion structure similar to the tail of a rocket into the bullet. After the bullet leaves the barrel, the power propulsion structure starts working, continuously increasing the kinetic energy of the bullet.

With the same bullet caliber, the power of explosive weapons is several times greater than that of gunpowder weapons! And thanks to the power propulsion structure, the bullet caliber of explosive weapons can be designed to be larger, and the types of bullets are also more diverse.

Armor-piercing bullet with a core made of high-hardness material.

A high-explosive bomb with built-in fuse and explosives.

An incendiary bomb loaded with chemical fuel.

Or they use optical fuses, which cause the explosive bomb to split into fragments before hitting the target to expand the killing area.

……

"If I had known that this would be the thing I drew, I might as well have promoted plasma weapons directly!"

The reason why he doesn't promote plasma weapons is because it's too IMBA. Ordinary people can use it to produce the destructive power of an elite monster's full-strength attack. Ordinary God's Eye holders can't match it at all.

Its appearance will only escalate the existing war on Tewat, and eventually evolve into the Second World War after the Demon War.

Of course, it is also possible that before the plasma weapon spreads in Teyvat, Tianli wakes up and blows Shen Qin to pieces.

Compared with explosive weapons and plasma weapons, the only advantage is that the power of some individual weapons is not too exaggerated in Teyvat, at least it will not be IMBA to the extent of attracting the pursuit of the law of nature.

He had a headache and decided to check if there were similar weapons on Teyvat tomorrow and analyze whether the appearance of explosive weapons in this world would cause any chain reaction.

The next morning, Shen Qin took Klee to the library to look up information. She also liked reading storybooks, so she didn't raise any objections. The only regret was that Fischl, who often read books with her, followed the adventurers to the front line and was not in the library.

Shen Qin spent the whole day looking through dozens of old books and discovered that thermal weapons were once used on a large scale when Kanreya was at its peak. Many relic machines are still equipped with thermal weapons today, but they all rely on scarce chaotic energy to drive them, so they cannot be mass-produced after the loss of Kanreya technology.

There are also individual thermal weapons in the world that are powered by the elemental force of the Eye of God, but ordinary people cannot use them.

Shen Qin breathed a sigh of relief. At least he didn't have to worry about the appearance of explosive weapons, which were also thermal weapons, attracting too much attention from others.

What he should worry about now is whether the parts processing accuracy can reach the level that every weapon can pass the mass production. After all, the flying skateboard and bionic prosthesis he had before had a bit of alchemical metaphysics, but now he has in his mind the technology of explosive weapons with pure mechanical structure.

He can't possibly build a machining lathe, he doesn't even know how to use that thing.

No, it has to be changed! We need to combine the metaphysics of alchemy to reduce the difficulty of processing explosive weapons.

And he has already thought about what kind of individual explosive weapon to develop - an individual explosive rifle!

This is a very versatile explosive weapon. It can be used for precise bursts at long range and quickly empty the magazine at close range. It just may need to have its structure and power slightly optimized. Space Marines have the blessing of power armor and can ignore its recoil, but ordinary people in Teyvat may have their arms torn off by the powerful recoil after just one shot!

Shen Qin also found a lot of blueprints and information on Teyvat's thermal weapons in the built-in database of the bracelet. He referred to their technology and made modifications to the original prototype of the bolt rifle.

Gunpowder is not a problem. Klee has mastered the methods of making various types of gunpowder. She just needs to adjust the explosive power to the appropriate size.

As long as the buttstock, grip and other things can be used, there is no requirement for the processing accuracy.

The firing device, return device, gas device and magazine have certain requirements for accuracy, but it is not that important. It is enough as long as they can ensure normal operation without malfunction.

The only two things that need to be adjusted are the barrel and the aiming device. The barrel has the highest requirement for precision, that is, it must withstand the explosion of gunpowder for a long time without deformation or damage, and at the same time ensure the accuracy and acceleration of the bullet; the aiming device needs to slowly adjust the data after the barrel is formed.

Chapter 90: Cerberus, Death and Scythe

Shen Qin found a lot of blueprints and information of Teyvat's thermal weapons in the built-in database of the bracelet, and modified the grenade launcher based on the technology they used.

First of all, there was the gunpowder in the shell used to launch the bullet. He chose a formula that Klee had tried before - grinding the dried lizard tail into powder, adding it to a certain proportion of magic crystal and amethyst powder, and finally adding carbon powder made from burning pine wood.

In this way, the gunpowder can be directly detonated by the electricity of the electric crystal, so there is no need for a mechanical firing device. He used the saved space in the gun body to make a recoil reverse thrust device, which can reduce 80% of the shooting recoil.

He spent a day experimenting with the material for the gun barrel, and finally chose a tin alloy mixed with star silver ore. It has a strong heat dissipation capacity. If calculated at 500 bullets per minute, it can sustain continuous shooting for half an hour without deformation.

The buttstock, grip, recoil device, gas system, and magazine do not have high requirements for materials and craftsmanship, so he kept their original designs and did not add any unnecessary details.

Finally, as for the fuel used in the most critical power propulsion structure inside the explosive bomb, he creatively used overload fuel made from Jueyun Pepper containing fire element, Windmill Chrysanthemum containing wind element, and Tianyun Fruit containing thunder element.

Before the explosive arrow shell is fired, the powders processed from the three materials are placed in three independent compartments. When the gunpowder in the shell is detonated by the electric crystal, the three compartments will be blown into an interconnected state. At this time, the wind spreads the thunder and fire, and the contact between thunder and fire produces an overload reaction. The explosive energy is ejected from the jet hole at the tail of the power propulsion structure, pushing the warhead to accelerate.

In order to adapt to different combat environments, he designed a total of three grenade launchers of different specifications.

One is a bolt pistol, codenamed "Hellhound", with a magazine capacity of 20, an effective range of 150 meters, a caliber of 2 centimeters, and a small gun body. It is mainly used as a backup weapon or a main weapon in a narrow space. Due to the limitation of its structural volume, its lethality is relatively small, but if it hits the vital points of ordinary monsters within the effective range, it can still kill them in one shot, and can also cause certain damage to elite monsters.

The second type is a bolt rifle, codenamed "Death", with a magazine capacity of 40, an effective range of 2,000 meters, and a caliber of 2 centimeters, but the longer barrel allows it to fire bullets faster and with greater lethality, capable of blowing up ordinary monsters with one shot and causing serious injuries to elite monsters. It can be used as a regular main combat weapon for the troops.

The third type is a machine gun with a bolt action grenade, codenamed "Sickle", with a caliber of two and a half centimeters and an effective range of three thousand five hundred meters. The barrel is thicker and longer, and the recoil is so great that it needs to be supported on solid ground. It has a firing rate of two thousand rounds per minute and is fed by a belt. A belt holds two hundred rounds, and three shots are enough to blow up an elite monster!

He designed five different types of bullets for both calibers.

Standard bolt bomb - steel core, built with the same explosive as the bomb that Klee gave him last time for self-defense, but almost killed herself because Bennett slipped.

Sea Monster Armor-Piercing Bullet - The length is one and a half times that of the standard bullet, the fuel in the propulsion structure is more sufficient, and the kinetic energy is greater. The core of the bullet uses a stronger crystallized bone marrow-white iron alloy, which can easily penetrate the shield of the Hillock Thug or the enemy's armor, causing direct damage to the target.

Ten-Direction Thunder Bomb - the built-in explosives have been replaced with unstable electrical crystal fragments. After hitting, it will form a high-voltage minefield with a diameter of three meters. It is mainly used to deal with mechanical monsters such as ruins guards, and can also be used to break fire and grass attribute shields.

Purgatory Incendiary Bomb - Use the synthetic powder of Flame Flower instead of explosives. After hitting the target, the Flame Flower powder will stick to the skin, clothing surface, or scatter in the air. It will explode after five milliseconds and is used to break ice, water, thunder, and grass attribute shields.

Zero-degree blasting ice bomb - contains ice mist flower synthetic powder, which will quickly emit ultra-low temperature ice mist after hitting the target, which is used to break the shields of fire, lightning and water attributes.

While Shen Qin was immersed in weapons research, the Knights' clearing operations against the Abyss Cult and monsters were in full swing. Anyone with a discerning eye could see that their victory was in sight, it was only a matter of time.

Keqing led Liyue's Thousand Winds Army on several missions, and achieved considerable results each time. She also received a top-of-the-line skateboard from the Knights Templar and personally experienced the combat power boost it brought to the team.

This made her realize the importance of Shen Qin even more. So in her free time, besides staying in the guesthouse to work on Liyue's development plan, she would go to his alchemy workshop to make friends with him.

That day she came to the alchemy workshop again. As soon as she entered the door, Haro floated in front of her and greeted her politely: "Hello, hello!"

"Good afternoon, hello!" She waved at it with a smile.

It silently floated back to the corner of the ceiling of the room, ready to protect Shen Qin at any time.

She looked at it with some envy. During the first dragon disaster, it had performed very well in guarding the city gate. Although this news was intentionally blocked by the Knights Templar and the Adventurers' Association, she still learned the detailed information through some special channels.

The weapon hidden in its body is extremely powerful and can be used by ordinary people. If the Thousand Winds Army can be equipped with this kind of weapon, it will not be long before Liyue can achieve true "rule of man" without having to rely on the protection of the immortals.

"Sister Keqing!" Klee and Xiaodu behind her waved at her in sync.

“Klee, Xiaodu.” Keqing came to Klee’s side and looked at the locked door on the side of the alchemy workshop. “Hasn’t he come out yet?”

Shen Qin had previously asked the Knights to help break down the wall between the alchemy workshop and the empty house next door, expanding the alchemy workshop. He then stayed there for five consecutive days, saying that he wanted to research a new invention. Even his three meals a day and alchemy materials were brought back for him by Klee from the Deer Hunter and the Adventurer's Guild.

"Yes, but Brother Shen Qin said that everything can be done by this evening!"

As soon as she finished speaking, she saw the door opened, and Shen Qin walked out. He was dirty, his hair was a mess, and his dark circles under his eyes were darker than a panda's.

"Brother Shen Qin!" Ke Li shouted happily.

“Klee, Keqing is here too.” He looked up at them feebly, then turned and walked towards the master bedroom. “I’m going to catch up on some sleep first.”

After walking a few steps, he turned back and took out a ball of paper from his pocket and put it on the table: "Keli, help me ask the Knights for some things. Leave them at the Knights' training ground tomorrow morning. Then notify Captain Qin and ask everyone who is free to go to the training ground tomorrow morning. I have important alchemical products to show them."

"If Keqing is free, let's go together then."

After he finished speaking, he went into the bedroom and closed the door, leaving Keli outside the door and pouting in dissatisfaction: "Damn it, Brother Shen Qin ordered Keli to run errands for him again!"

Keqing looked curiously at the locked door leading to the new area of ​​the alchemy workshop.

With such a big momentum, has he developed any powerful new products?

Chapter 91 Decision

Shen Qin slept until the next morning. He took a shower and changed into clean clothes. All the fatigue in his body was gone, and he felt refreshed.

Young people are in good health and can restore their normal mental state after a good night's sleep.

He moved the weapon box containing three grenade launchers and dozens of bolt shells onto the skateboard, walked towards the Knights' training ground, and picked up a breakfast at the Deerslayer on the way.

When he arrived at the training ground, several members of the Knights, Diluk and Keqing were all there. They all looked at the big box on the skateboard, knowing that it must contain the new invention he was going to demonstrate this time.

"My dear friend, all of us dropped our work and rushed back just to see your new invention. If it doesn't satisfy us, you will have to take the responsibility!" Kaia joked with a smile.

"Kaeya, don't be so harsh on the little cutie. Everyone's nerves have been tense for so long, so just relax when we return to Mondstadt." Lisa looked at Shen Qin, "But the little cutie has made something new again. It seems that he is smarter than me. Why don't we let him study the wind dragon barrier instead of me!"

You just want to go back to Mondstadt and be lazy!

Qin nodded to Shen Qin: "Shen Qin, please show us your new invention. I believe that the fact that you called everyone here at this time means that it will definitely be helpful to our battle situation."

As expected of the leader of the Qin Band, his mind is still so sharp.

Shen Qin admired in his heart, and asked Kaiya to help move the weapons to the flat ground, then opened it, revealing three very exquisite grenade launchers and a wide variety of bullets inside.

They were the first three grenade launchers in Teyvat. Shen Qin planned to collect and use them himself, so he spent some time on painting the surface.

The metal part of the gun body is all gray-black fine matte texture, with the silver-gray double-headed eagle logo of the Human Empire in Warhammer 40k printed on it, reflecting a dim light under the light, in order to avoid the reflection of the gun body exposing its position to the enemy.

"Is this... a weapon?!" Qin exclaimed.

When she received the notice from Klee yesterday to prepare plates of various materials and thicknesses, she began to doubt whether this new invention was a weapon. After all, the performance of the Dragoon I on the battlefield was so outstanding.

Before the clearing operation, she had asked Shen Qin whether it was possible to mass-produce the Type I Dragoon, but he said that its spread would cause panic among other forces in Teyvat, which might then cause Mond to become the target of public criticism, and the result would be counterproductive.

Unexpectedly, his new invention this time turned out to be a weapon.

"Yes, they are indeed weapons, and very powerful weapons." Shen Qin looked at everyone expressionlessly and spoke very seriously, "I developed it because of the current special situation. If it is put into the battlefield, it is guaranteed that the Knights will achieve the final victory within half a month, but it will also lead to very serious consequences."

"After a very short period of training, ordinary people can use it to unleash the destructive power of elite monsters. If it is not controlled, the damage it will eventually cause to Mondstadt may be greater than the Knights taking several months to clear out the monsters and the Abyss Cult!"

"Moreover, it can allow ordinary people to have combat power comparable to that of God's Eye holders. A few dozen God's Eye holders can only play a very limited role on the battlefield, but a few thousand God's Eye holders can form an invincible army on the battlefield. If the Knights implement it, they must be prepared to face the pressure from other forces."

"And it should be the cornerstone of peace, not a tool to invade other countries." Shen Qin's words were very obscure, but he knew Qin could understand.

"So you'd better discuss it and decide whether to release it or not."

The members of the Knights looked at each other in surprise. If what Shen Qin said was true, then the impact of this new weapon would be greater than they imagined. To put it seriously, it would even change the current balance between the various forces in Tewat.

Keqing and Diluk also stared blankly at the three weapons lying quietly in the box.

Diluk glanced at Qin, who was frowning in thought, and said to Shen Qin, "Your description of the characteristics of the new weapon is not very intuitive. Why don't you show it to us first so that we can make a better judgment."

"no problem."

Shen Qin asked everyone to place five one-centimeter-thick alloy steel plates at intervals of twenty centimeters at a distance of twenty meters. As for why they were placed so close... he was worried that if they were any farther away, he would miss the target!
