In this era with almost no technology, Gu Qing had two choices, the flintlock gun and the matchlock gun.

In contrast, flintlock guns are more advanced than matchlocks, fire quickly, and are not subject to climate restrictions, but the manufacturing process is complicated.

Originally, Gu Qing did not have to choose to use gunpowder guns, but he still did not dare to despise the wars of this era. Under the premise that the technology could be realized, using weapons that surpassed today's technology would give him more control.

In front of Gu Qing were several small baskets, which Han Jie had collected for him according to his instructions, including flint, sulfur, charcoal, saltpeter, eggs, as well as several small trigger parts made by blacksmiths, etc.

Seeing Gu Qing playing with the things in the small basket, Han Jie was confused and asked: "Why are you preparing these irrelevant objects?"

Gu Qing said without looking back: "You will know later."

After collecting all the things, what Gu Qing has to do is to combine them into something terrifying.

After finding a small stone roller, Gu Qing personally pressed the charcoal and sulfur into powder. While pressing, he asked, "Sulfur and charcoal are easy to talk about. Where did you get the saltpeter?"

Han Jie said inexplicably: "There are several medical clinics in Qiuci City. I will buy it from the doctors at the medical clinic."

Gu Qing turned to look at him in surprise: "Is saltpeter a medicinal ingredient?"

Han Jie became more and more confused: "Of course it can be used as a medicinal material. Saltpeter is also known as 'ground frost'. It is warm in nature and bitter in taste. It has the effect of releasing heat, laxative, clearing heat and detoxifying. Doesn't Mr. Hou have constipation? In fact, it is in the laxative you take.

It contains saltpeter..."

Gu Qing was stunned and glared at him again: "Mr. Mo is talking about my constipation. Didn't Bian Jianjun also take laxatives? You can talk about him taking laxatives."

Lowering his head and continuing to crush charcoal and sulfur, Gu Qing asked again: "Did anyone know when you bought these things?"

Han Jie shook his head: "No, the general knew that the Marquis was going to do something ulterior, but he didn't tell anyone."

Gu Qing hesitated for a moment, then sighed.

Sometimes it's hard to understand what this guy's talking about. It's hard to tell whether he's deliberately being mean or ignorant. Can the word "unscrupulous" be used here?

Although it is indeed ulterior in nature.

"Han Jie, the wife and concubines you married in Guanzhong were probably not pursued by you, right?"

Han Jie scratched his head: "I was hired by the elders in the family."

"No wonder, if you rely on your words to pursue a woman, you will turn against her at the first meeting..." Gu Qing sighed sadly: "You can solve the problem with money, why can't I solve it with money?"

I remember that when I proposed to Zhang Huaiyu, I gave him a full twenty taels of silver cakes, but Zhang Huaiyu still didn't agree to it.

Maybe I thought the money was too little, so I had to pay more. The prime minister came from a good family, and his class was very high, so he was a high-consumption person.

Later, before leaving Chang'an, he gave her a breast shield made of gold. She must have been so moved that the marriage was stable the next time I saw her.

Han Jie, however, did not understand Gu Qing's worries and said in confusion: "Master Hou, money is a good thing. From eating, drinking, having sex, to getting a wife and having children, everything can be solved with money. Is there anything that money can't solve?"

"If I cut your neck with a knife, can you buy your life back with money?" Gu Qing said coldly.

Han Jie said without hesitation: "The person who used the knife was bribed in advance to avoid the vital points on the neck when the knife was used, and his life was bought."

Gu Qing pursed his lips.

The impeccable logic left Gu Qing speechless.

The work at hand did not stop, and soon Gu Qing crushed the charcoal, sulfur and saltpeter into powder, cracked the eggs open, took only the egg whites, and filled a large skin bag.

Then Gu Qing stood up to greet Han Jie and led a dozen personal guards out of the camp.

Outside the camp was a vast desert. Gu Qing pointed in a random direction and the group of people galloped away.

They were far away from the camp, probably dozens of miles away, and dismounted in the middle of the desert. There was no one around. Gu Qing was still worried and ordered his guards to spread out and keep a distance, not allowing anyone to approach.

He and Han Jie sat cross-legged on the yellow sand. Gu Qing took out a portion of the charcoal, sulfur and saltpeter, and first mixed them according to the standard proportions, 1.5% charcoal, 1.5% sulfur and 70% saltpeter, and packed them

Put it in a basket, then sprinkle some egg white and shake constantly to form a granular shape.

The climate of the desert is dry, and the black powder quickly dried.

As for the purity required for this thing, Gu Qing really had no choice but to wait until the technology matured before further improving it.

After shaking for a long time, the three things were evenly distributed. Gu Qing combined the iron pipe and the butt, and installed the trigger and flint under the butt. A flintlock gun in its original shape was ready.

Stuffing a small amount of gunpowder into the iron pipe, and then loading an iron pellet slightly smaller than the diameter of the iron pipe, Gu Qing finally ordered Han Jie to set up a human-shaped target around a hundred steps away, and the flintlock gun was fixed on a simple stand.

, a long string was tied to the trigger, Gu Qing walked away step by step holding the string, and did not stop until he was ten steps away.

Han Jie looked at Gu Qing's movements in confusion and asked, "What exactly is the Marquis going to do? Why are you so careful?"

Gu Qing sighed: "Because it is very dangerous to experiment with this thing, I don't know if I have been matched. If I were a little crueler, I should have let your personal guards carry it for the experiment. You have accumulated good deeds in your previous life, and you met me as a benevolent and righteous person."

My unparalleled good boss, I can't bear to see you pay the price in casualties, so I have to settle for the next best thing..."

Han Jie was still puzzled. He didn't understand that it was just a weird weapon. Why was the Marquis so cautious? Could it come alive and bite people?

Only Gu Qing knows that if the experiment succeeds, this thing will be a hundred times more powerful than a dog that bites people.

After making sure that he kept a safe enough distance from the gun, Gu Qing held his breath and stared nervously at the flintlock gun in the distance, holding the rope in his hand and pulling it little by little.

Han Jie didn't think so at first, but seeing Gu Qing's nervous expression as if facing a formidable enemy, he couldn't help but become nervous. He cautiously looked at the strange-shaped thing in the distance, and then stood attentively beside Gu Qing, as if he was ready to give up.

The appearance of a life escort.

Gu Qing pulled the rope suddenly and pulled it back hard. The trigger tied to the rope was immediately pulled. The trigger was connected to a flint that could shoot out sparks, and then...

Huh? No movement?

Gu Qing waited patiently for a while, feeling that this broken gun was unlikely to surprise him, so he stood up in disappointment.

Han Jie looked at the gun inexplicably, his expression even more disappointed than Gu Qing's.

You've taken off your pants, that's it?

Gu Qing stepped forward to inspect the gun, poured the black powder out of the barrel and studied it carefully for a long time, but still couldn't figure out the key.

This is very helpless, and I can't even find the reason for the failure.

Gu Qing stood there without moving for a long time, his expression was dull and he didn't know what he was thinking.

Seeing his dejected look, Han Jie couldn't bear it, so he comforted him: "It doesn't matter if the Marquis's new weapon doesn't work well. Our Anxi army has a sharpshooting camp, a Modao camp, a halberd and a volley of spears. We must

No matter what you have, whether you have new weapons or not, you are invincible."

Gu Qing sighed and said: "It's not that I can't accept failure. What I can't accept is that my image in the eyes of others is shattered..."

Turning to look at Han Jie, Gu Qing said quietly: "I guess after witnessing the failure this time, my perfect image in your eyes is no longer so perfect, right?"

Han Jie was stunned and speechless for a long time.

Having owed the female shopkeeper so many meals, the guards already knew how thick-skinned the Marquis was, but they still underestimated it after all.

You are the Marquis, you are the coach, you are the club, but you really have never been perfect. At least a Marquis who has unpaid debts and is constipated cannot be called "perfect" in any way.

Han Jie was silent for a long time, cupping his fists and saying: "Master Hou, a momentary failure is nothing. You will always be the perfect Master in the eyes of the general."

Gu Qing was finally happy and showed a relieved smile.

Men and women actually have many of the same problems, such as the need for others to coax them.

Stepping forward to observe the failed flintlock gun, Gu Qing studied for a long time and finally discovered the problem.

The first is that after the trigger is pulled, the mechanism does not hit the flint with enough force to produce sparks. The second is that there is a problem with the gunpowder. It is not the ratio, but the purity is not enough. The impurities in the sulfur and saltpeter need to be screened out before making black gunpowder.

.

After finding the problem, there was no rush. He went back to draw a blueprint and asked Juan to build a mechanism for striking flint, and then figured out how to improve the purity of the black powder.

"Let's go back to the city. Tell the guards that what happened today is top secret and no one is allowed to tell it."

…………

The lyrics sing well, "No one can succeed casually."

Gu Qing went into the commander's tent to study the impact mechanism and the removal of impurities from black powder day and night. The city of Kucha remained calm as usual.

It is said to be "peaceful", but in fact it is not that peaceful. It is inevitable that good and bad will be mixed in a city, especially in a city where Han people and barbarians live together. As Qiuci City becomes more and more prosperous, after the Anxi Army suppressed bandits several times, the merchants of the Western Regions

The roads have become much safer, but the security problems in Kucha City have become prominent.

There are more people and businessmen in the city, and naturally there are more petty thefts. Recently, many businessmen have come to the Jiefu to report to the government, crying and claiming that their money has been stolen. Not only that, there are also a few more hiding places in the city.

In the shadows, gangs of evil forces wandering on the edge of the law are exclusively extorting money from businessmen and ordinary people.

As more and more people reported to the official, Gu Qing finally heard the voices from the common people and businessmen. With Gu Qing's temper, he would not be used to these thieves and evil forces, so he first ordered a crackdown on the bad guys in the government.

Shuai Shi recorded military sticks and severely punished him for his incompetent governance, and then mobilized a thousand Anxi troops into the city and launched a Tang Dynasty version of the anti-gang and evil operation.

All suspects who were caught were severely punished. Those who committed major crimes were taken directly to the market entrance and beheaded. Some leaders and members of small gangs with bad records were given heavy sticks and beaten to half disability. As for those who committed petty thieves, they were severely punished.

After being taken down, they were thrown into the engineering team to do hard work. The city expansion project has not stopped. The thieves have food and drink inside, and they should feel like home.

After this, the public security in Kucha City improved overnight. The people and businessmen were all happy, and they even praised Gu Qing. Even the business of Fuzhi Inn was full every day.

I don't know who spread the scandal about Gu Qing's close relationship with the female shopkeeper of Fuzhi Inn. The common people and businessmen could not express their gratitude to Gu Qing, so they took care of Huangfu Sisi's business, which could be regarded as expressing their gratitude to Lord Gu.
