The light wind is very cool after the rain. (《》)

The wind blowing from the Bian River is even more chilling.

Although it was mid-autumn, the weather was gradually getting colder. After a light rain at noon, the temperature dropped a lot.

Yu Yin rode on the horse and shook the cicada.

He wrapped his clothes tightly, looked up at the sky, and immediately whistled, and Danjin immediately accelerated his speed. In short, it took several months for him to cooperate with Danjin, and the tacit understanding between people and horses reached the extreme.

Although Dark Gold is old, her feet are not inferior to those of BMW.

Its biggest advantage is its calmness and long endurance. Perhaps it has experienced too many big scenes, so no matter when the dark gold is, it will never panic, and it always has a bit of stability. Yu Yin’s favorite is exactly this.

Dark Jin ran wildly with his hooves on his back, and about an hour later, he arrived at the Mutuogang Imperial Camp.

Along the way, you can see the Tokyo Imperial Guard patrolling the official road, which also made Yu Yin feel a little more worried.

Feng Kuang told him that the court would soon expand the scope of the investigation outside.

In other words, sooner or later, someone will inspect the imperial camp.

Although Ling Zhen can be assured, there are always risks.

It was okay for the horses to be said, but the three horses changed colors and were branded with military horses.

At the same time, Ling Zhen also reported three horses through military weapons supervision. Even if they were discovered, there would be no trouble.

The most important thing is the jewelry worth millions!

I don’t know how Liu Qing was preparing? If he could set out in advance, it would be the best choice.

But the question is, how can you get Liu Qing to set out in advance?

Yu Yin had a headache and unknowingly came to the gate of the imperial camp.

This was not the first time he had come to the Imperial Camp, so the soldiers on duty did not stop him, so he asked Yu Yin to enter the camp directly...

As soon as I got off the horse, I suddenly heard a loud noise coming from the direction of the school ground.

The sound was like the sky collapsed and the earth was broken. Standing there, you could still feel the trembling on the ground.

Although Dark Gold was calm, it also felt a little restless under this situation. It shook its head and tail, sniffed from time to time, stepped on the iron hooves and even wanted to break free from Yu Yin's hand. Yu Yin quickly pulled the reins tightly, then reached out to hug Dark Gold's neck, pressed his face against Dark Gold's face, and whistled softly.

This is also a way for Yu Yin to communicate with Dark Gold.

"Don't be afraid of Lao Jin, it's okay, it's okay!"

Under Yu Yin's comfort, the dark gold gradually stabilized.

"What is the matter with General Ling?"

"Uh, today Ling Zhengzheng's new cannon trial... Haha, I don't know if it has been successful."

Trial new cannon?

Or, it is a trial of new shells.

As the commander of the Gunpowder Bureau, Ling Zhen’s love for artillery is beyond replenishment.

He often experiments with new recipes and conducts experiments in the imperial camp. Anyway, his imperial camp is a place where his grandmother doesn't love and his uncle doesn't like it. From top to bottom, it can be said that he is the only one who decides. Now he has hooked up with the Palace Front Office, and his relationship with the Military Equipment Supervisor has improved a lot. At least in terms of military pay, the Military Equipment Supervisor will no longer be deducted as before.

Ling Zhen’s imperial camp was filled with 500 people.

But in fact, the number of people in the Imperial Camp of the Gunpowder Bureau is no more than 300.

In addition, some craftsmen did not report to the Imperial Camp. Although they were under the jurisdiction of the Gunpowder Bureau, they were actually reported to the military weapon.

In this way, Ling Zhen can earn at least 200 people a month without pay.

Anyway, the Gunpowder Bureau did not go to the battlefield, and no one would ask about it in detail. Occasionally, someone came to check the number of people, and Ling Zhen used the craftsmen to make up the number, so that his life was quite stable. The empty salary of 200 people gave Ling Zhen enough funds to conduct experiments. He often studied some new artillery and experimented in the imperial camp, but no one was concerned about it.

Yu Yin smiled!

He came today for this.

He immediately led the dark gold into the stable and headed straight to the schoolyard.

The schoolyard of the Gunpowder Bureau was bumpy and looked extremely broken... At this time, a group of people were gathering on the edge of the schoolyard, shouting loudly.

That's right, it's just yelling!

But don't get me wrong, they are not arguing, but discussing the experiment just now. The latest chapter of the Holy Church

It was just that the explosion was so loud that everyone's ears were useless, so they could only shout loudly at the top of their throats.

Even Gao Chong stood aside.

"Zhisanlang!"

Gao Chong didn't move.

"Zhisanlang..."

Gao Chong still didn't respond.

Until Yu Yin walked forward and patted Gao Chong on the shoulder, Gao Chong immediately instinctively slapped Yu Yin with a backhand. Yu Yin hurriedly dodged, "Shisanlang, it's me!"

"Brother Xiao Yi, why are you here?"

Gao Chong shouted at the top of his voice.

Yu Yin was very close to him, and was almost deaf when he shouted.

"What do you do with such a loud voice?"

"ah?"

"I'm talking about you, why are you doing such a loud voice?"

Gao Chong rubbed his ears and said, "I can't hear clearly, I can't speak loudly, I can't hear clearly."

OK, then stop talking... The aftermath of the explosion has not yet been eliminated, and it is estimated that it will not be able to return to normal in the short time.

At this moment, Ling Zhen came over.

"Why is Xiao Yi coming?"

"Uncle Ling, it was a big noise just now."

However, as soon as he said this, Yu Yin felt regretful. Even Gao Chong became like this, and Ling Zhen was probably not much better.

But Ling Zhen laughed and said, "Yes, it's loud, but this power is not enough."

"Wealth...Huh, Uncle Ling's ears are fine?"

Ling Zhen smiled and stretched out his hand, and saw a pair of wooden earplugs in his hand. "How could he not be prepared for the fireworks all year round? In fact, most people here are used to it, but the noise just now was a bit unexpected, which caused this situation."

When Yu Yin heard this, he hurriedly asked, "Uncle, what's the result?"

"Xiao Yi is also interested in gunpowder?"

Ling Zhen asked curiously, and without waiting for Yu Yin to reply, he pulled him toward the schoolyard.

The air was filled with a smell of smoke, which was extremely pungent. The feeling was like the New Year in later generations, and the smell of firecrackers in the yard was produced. There was also a faint light smoke floating in the schoolyard. Ling Zhen took Yu Yinshen and walked to a stone with one foot shallow and pointed to the broken corner below, with a helpless expression on his face.

This stone is called the Ignition Monument in the Imperial Camp.

The stones were covered with pits and pits, and they obviously had experienced countless trials.

"I thought that half of the ignition monument could be collapsed, but I didn't know that only one corner was broken.

This ignition monument is here when I enter the Gunpowder Bureau. Every time I test the gun, I will use this as the basis to test the power.

Xiao Yi, you don’t know.

When I entered the Gunpowder Bureau, I made an oath to collapse the ignition monument.

But for more than twenty years, this guy is still here, but I am already old... If this guy cannot collapse in my lifetime, I will die with my eyes open."

After countless explosions, the ignition monument was smoked black.

When Ling Zhen said this, he could be said to be gritting his teeth, but he could not do anything about it.

Yu Yin squatted down, looked at the shallow pit under the ignition monument, and couldn't help asking curiously: "How did my uncle try the cannon?"

Ling Zhen had no intention of hiding it, so he told Yu Yin about the process of his test shot.

In fact, most artillery artillery in the Northern Song Dynasty were mainly thrown, but on the basis of throwing, the power of gunpowder was increased. However, the gunpowder in this period was not yet fully mature and had not yet evolved into the later black gunpowder. According to the "Wu Jing Zongyao", the gunpowder in the Northern Song Dynasty did not leave the category of arson burning.

Therefore, the firearms of the Northern Song Dynasty, whether they are thunderbolts or thunder, are not too lethal.

Its function is mostly to generate huge airflow, or torture. Although this kind of firearm also has a certain degree of explosive power, its lethality is not too strong. Until the Southern Song Dynasty, with the emergence of tubular firearms, gunpowder gradually matured, and began to transform from the initial burning and arson, as well as deterrent effects to large-scale killing...

When the Yuan Dynasty destroyed gold, the production process of the Shi Tianlei changed drastically.

The "History of Jin" describes the thunder as the sky: gunpowder erupts, the sound is like thunder, the heat reaches more than half an acre, the man and the cowhide are broken and there is no trace, and the armor and iron are all penetrated.

This description may be exaggerated, but it can be seen that the ratio of gunpowder at this time has gradually become perfect...

Yu Yin hesitated for a moment and said softly: "Can uncle explain the process of configuring artillery with Xiao Yi in detail?"

"What's the difficulty!"

Ling Zhen smiled cheerfully and saw the chaos around the school grounds. "I talked so much here, so I went to the hall to talk."
