Li Yuan leaned on the soft couch and recalled the events of the year. Pen & Fun & Pavilion www.biquge.info

When he raised his own army, the Turkic soldiers pressed Jinyang, and he was not allowed to claim to be a vassal to the Turks, and until now, theoretically the Tang Dynasty was still a Turkic courtier. But Li Yuan was unwilling, he pacified the world and unified the Central Plains, he was already the emperor of the Tang Dynasty, how could he be a vassal to the Turks.

Therefore, in the battle of the state, Li Yuan couldn't wait to go into battle in person.

But he knew he couldn't, he was the emperor of the Tang Dynasty. But he was waiting, he believed in Qin Qiong, Qin Qiong's guarantee was something he believed very much, Qin Qiong said that even if he couldn't defeat the Turks completely, he would have to be hit hard. Even if you can't kill Jieli, you have to cut off Jieli's arm.

Li Yuan knocked lightly on the table, he could feel the prosperity of Datang.

In the south, Li Xiaogong and Li Jing pacified Jiangnan, and there will be no more rebellions there. In the north, there is his son Li Shimin, who can fight well, secretly commanded, and there are Qin Qiong, Chai Shao, Cheng Yanjin, Li Ji and other generals leading the troops, and it is the time for the Tang Dynasty to revitalize the country's prestige.

(Note: In history, the Tang Dynasty was a vassal to the Turks for 12 years, and it was not until the third year of Zhenguan that Li Jing invaded the Turks and captured Jieli alive)

Mihara.

When Liu Mu returned home from a big purchase, Li Bi was responsible for going to the pig's trotters.

Li Dejian was absent for the past few days, and he arranged for someone to make a quyuan plow in his home. There are patterns that can be made, but the specific data still needs to be tested, Liu Mu just knows that the seventh one has been made, the length of the handle, the angle of the plough blade, etc. are still being adjusted, and it seems that it can be adjusted and improved by manpower in the garden.

Willow Wood walked around in a circle, and everyone was busy as scheduled.

A messenger arrived.

Now that the gift of Nacai has been completed, the next step is the formal gift of asking for names.

Asking for a name is a small gift, and then it is a big etiquette, in the Tang Dynasty, Najib and Nazheng are generally done at the same time, Najib refers to the birth date when asking the name to take back, and then after there is no problem, tell the woman that it is very good, and at the same time send gifts to the door, for the official engagement.

Liu Mu sat in the house and was very depressed, because he had planned an officiating ceremony for recruitment, but now that he was going to war, what should he do about this officiating ceremony, this thing would definitely not be made by changing people.

Headache!

Willow closed the door and hung a wooden sign on his door with a Do Not Disturb.

Inside the house, Liu Mu first took out the bronze mirror from his own special small stone mill, then removed the cork and replaced it with the upper half of the stone mill of pure stone.

The nitrate soil is ready, mixed with plant ash to neutralize and extract potassium nitrate.

The chemical equation is very simple.

The main principle is to use potassium ions in plant ash to replace sodium ions in nitrate, so as to generate potassium nitrate. In addition, the carbonate ions and sulfate ions in the plant ash combine with the calcium and magnesium ions in the nitrate to form insoluble salts and precipitate, thereby removing impurities such as calcium and magnesium.

All this, Liu Mu has been preparing in secret for a long time.

For now, willow wood needs to grind fine charcoal into powder and sulfur into powder.

Outside, the snow was falling, but the willow wood was engrossed in the house.

There is no weighing, willow wood makes a balance, and weighs it with a brand new copper coin on behalf of the weight, as long as it reaches the required ratio of seven or five, one zero, and one five.

Then there's mixing.

Finally, Liu Mu added water to these powders, then pressed them into cakes, dried them, tore a little charcoal powder and kneaded them into granules, and packed them in bamboo tubes one by one.

There is a cellar about one and a half meters in diameter and one meter deep in the house, which is where the willow hides the treasures.

After the first batch is made, the willow wood is wrapped in cloth, the secret door under the bed in the cellar is opened, and then the bamboo tube is placed in the clay pot and sealed tightly with mud.

A jar of twenty catties, and Liu Mu carefully placed it in the corner of the cellar.

Coming up from the cellar, Willow held the corner of the table with one hand and an oil lamp in the other.

Suddenly, a thunderclap sounded, and when the thunder reached Liu Mu's ears, the big locust tree outside the house had been struck by lightning. Yanagi was startled by the thunder and hit his head against the corner of the table.

I saw that the bamboo tubes filled with black powder on the table overturned, and then the oil lamps on the table also toppled over.

"it......," the willow monster screamed, turning over and about to hide in the cellar.

panicked, but let Liu Mu himself jam the door of the cellar, Liu Mu in his heart countless alpacas lined up, no time to scold the street, quickly ripped off the quilt from the bed, Liu Mu got under his bed and rolled up in a ball and shrank in the corner, with the quilt in front of him.

The flame of the oil lamp burned the remaining charcoal powder on the table, and then the bamboo tubes filled with black powder.

This time, there were about fifty catties of raw materials, forty catties had been placed in the cellar, and the rest were on the table and had not yet been put into clay pots.

Willowwood rolled up in the corner of the bed, tucked strips of cloth into his ears, and then held his ears tightly with both hands.

A dull thud was followed by a loud thud.

With the willow hut as the center, you can feel the earth shaking at least a hundred meters around, and Li Bi, who is sitting outside the kitchen door munching on pig's trotters and sipping wine, is still happy.

"It's a big tree, it's been struck by lightning. It's a pity, it's a pity, it's a pity, it's summer......

At this moment, the loud noise came out, and Li Bi fell to the ground in shock, and all the rooms shook slightly. It was ten catties of packed black powder, no matter how weak it was, there were ten catties, even if it was scattered, without packaging and compression, it was also ten catties of black powder.

The roof of Liu Mu flew up, the walls of the house fell outward, and the whole house was reduced to ruins under Li Bi's eyelids.

Li Bi was stunned.

"Save people." The old wolf shouted and rushed forward with a dozen people.

When Li Bi heard this shout, he hurriedly rushed up.

With the efforts of dozens of people, Liu Mu was quickly found, and after lifting the wooden bed, the old wolf saw Liu Mu's posture, and his first reaction was that Liu Mu knew that there would be such a result, so he was protecting himself in advance.

At close range, only five meters away at most, the power of ten catties of black powder willow wood can be regarded as an experience.

This is at least equivalent to the power of two hundred two kicks to explode at the same time, Liu Mu is glad that he has been a soldier, and he also knows how to protect himself when he encounters such a thing, change people, he didn't hide at the time, and it is estimated that he will not die or be disabled.

The chest seems to have been punched a few times, and the head is buzzing, but fortunately there is a quilt and a bed in front of him, if he faces it head-on, it is estimated that he has hung up.

was rescued, Liu Mu saw that it was the old wolf, leaned on the old wolf and whispered: "Don't let people approach, don't turn over." After saying that, Liu Mu fainted gorgeously.

The old wolf nodded heavily, and he asked someone to lift the willow wood and send it to the house for treatment.

Then he ordered his soldiers to immediately ergo around the ruins with pillars and ropes, and no one should come near.

The old wolf probably guessed that this strange thing must have been done by Liu Mu, but there was some accident, otherwise why Liu Mu was rescued and hid under the bed in a state of self-protection.

Moreover, Datang's beds are mostly couches, and they can't get into people at all.
