After the seedlings, the paddy fields in Loosang Village were planted together by the clans and the supporters.

Compared with the people everywhere when planting rice, the subsequent field management only requires a few old farmers who are proficient in farming. Most of the young and strong women returned to the village to build a large amount of civil engineering.

Such people chew horses, and wine brewing consumes a lot of food. Fortunately, Liu Bei was foresighted, so he asked Geng Yong and Cui Jun to help him buy grain a few years ago. Now the water in Qingxi is large, so it is convenient to use a ship to traffic. Unfortunately, there are several silts in the wild forest, and large ships cannot pass.

Liu Bei then took people upstream to clear the river.

There are many rotten trees in the river. Good craftsmen went into the water to investigate and said that an ancient tree sinks into the water and studs across the river. They block dead trees falling into the river and break branches, which will become silt for a long time.

The ancient trees that sink into the water? Could it be the gloomy trees?

Gloomy wood is also known as ancient grimy wood. It is not deformed, has a heavy weight, is high in density and is moth-proof, and can be compared with red sandalwood. It can be called the essence of trees and the soul of trees. It has been regarded as precious wood and rare things since ancient times, and is a symbol of honor and status. It is the first choice for emperors of all generations to build palaces and make coffins.

Fortunately, there are not many taboos in this era.

As long as you can salvage the sinking wood ashore, Liu Bei can use it for his own use.

To salvage this thick and long ancient tree, you need to borrow a new tool and fixed pulley.

A river-crossing bridge is built on both sides of the river, and a pulley is placed on the cross-bowl. The water-good ones tie the hemp rope to a sunken wood. The cattle and horses on both sides of the river are pulled out of the water with their power. Then slowly pull it to the river bank.

Su Bo was overjoyed and said that this tree is useful.

Huang Zhong also came to ask for a branch and said he wanted to send it to Nanyang to create an artificial Yin Wood Bow.

Yinmu bow is also known as ebony bow. The good bow of the world.

Liu Bei naturally agreed.

After clearing the river, the merchant ship that Cui's family could carry 100 stones could flow downstream and reach Qingxi Ferry.

The salted wood of Tian family in Liaodong can also be transported by ship, saving a lot of time.

Liu Beisheng knew that the north was in this place and there were water networks everywhere, rivers and canals everywhere. Not only was there no shortage of water, but it was necessary to prevent water from being affected.

Seeing that the tools were losing a lot, Liu Bei found San Uncle to build iron tools.

San Shu said that the blast furnace should be started. Otherwise, the furnace temperature will not be enough and the iron ingot will be difficult to refine.

Isn’t the blast furnace smoke very large? Can Huang Xugang breathe freely for a few days, and then hold back his breath all day long?

Besides, such a beautiful countryside can be covered in black smoke all day long.

Huang Zhong said, why not drain water.

It turned out that in the early Eastern Han Dynasty, Du Shi, the prefect of Nanyang, invented water drainage (hydraulic blast furnace), using the river water impulse to rotate the machinery, so that the blower skin can be expanded and reduced, oxygenated to the furnace, and increased the furnace temperature. "If you use less force, you will get more skills and benefit the people." The invention of water drainage is a major advance in smelting technology.

How can people not love this era full of surprises?

I immediately moved my uncle to a steep slope downstream of Qingxi.

After the water drain was built, Liu Bei went over to see. He saw a wooden wheel in the torrent. The flowing water rotated the wooden wheel and drove through the wheel shaft, pull rod, etc. to turn the circular movement of the wooden wheel into a flap (bellows) up and down reciprocating movement, so that the leather blower bags can be opened and closed continuously to achieve the purpose of blowing.

This set of devices that transform circular motion into up and down reciprocating motion will be of great use if it is slightly changed.

So Liu Bei built another workshop on the other side of the steep slope. He lifted a stone pier through the rapids and then fell down. However, it was not used to make iron, but to crush the hemp mat.

It is completely different from making bedding mats, what Liu Bei wants to make is a nail piece.

Why do we need to start with a conversation between Huang Zhong and Liu Bei.

Huang Zhong asked, how to select the part (select)?

Liu Bei blurted out: He wore three armors (heavy armors all over the body), had twelve stone crossbows, carried fifty arrows, put them on them, had a crown and a sword, and won three days of food, and went to a hundred miles in the middle of the day (half a day).

Huang Zhong's sword-brow jumped: Shaojun wants to choose the Wushu of Wei?

Liu Bei smiled and nodded: It was Wei Wuzun.

One stone is equal to one hundred and twenty kilograms (30 kilograms). A crossbow with less than three stones is an arm opening. A crossbow with less than eight stones is a crossbow with less than ten stones is a crossbow with a waist opening. A crossbow with a waist opening of about seven stones can be opened. Only the waist opening can be opened with a strong crossbow. The bow opening position is "sitting up the foot and stepping on the crossbow". The crossbow hook is used to shoot with a hand-pulling crossbow string. That is to say, it is equivalent to using the whole body's strength to open a crossbow.

The limit of the arm strength of an ordinary person is only two stones. Huang Zhong can draw a three stone bow in a row.

An arrow shot out a hundred steps away, like a rainbow that penetrated the bull's eye!

The whole room was quiet, and then he cheered.

Geng Yong, who was beside Liu Bei, sighed in his heart again. Lousangwu Fortress has not been built yet, but he has found such a powerful general. How dare the thief come and call him?

Liu Bei came to him, which was naturally related to the burning of porcelain.

This time is different from before. Liu Bei actually fired a layer of porcelain glaze on the rectangular iron sheet.

Geng Yong recognized the style of the rectangular iron piece at a glance. This was the armor piece of the armor. Liu Bei wanted to make armor!

Zhajia, also known as Xuan Iron Clothes in the Han Dynasty, is a kind of armor with strong defense. The materials vary from time to time. It was bronze Zhajia in the Shang and Zhou dynasties, and after the Han Dynasty, it was mostly iron leaf Zhajia.

According to the different armor sheets, it can be divided into two types: one is rectangular armor sheet. The armor of rectangular armor sheets has two styles. One is made of two armors on the chest and back with belts and shoulders, and the other is also added with a hood, which has stronger defense. Both are ordinary soldier armor. The second type is a armor made of small fish-scale armor sheets, which is the general armor. The soldier armor weighs about 44 kilograms (11 kilograms), and it needs to be made of more than 650 armor sheets.

But what is the use of firing a layer of porcelain glaze?

Liu Bei laughed and said, this is called: enamel.

After a layer of porcelain glaze on the surface of the metal armor sheet, it can prevent heavy blows from swords and crossbows from breaking armor. During the war, the tanks were covered with porcelain glaze and the protection was amazing.

Geng Yong was skeptical.

Just as Liu Bei was unable to make gunpowder, he could only give a general direction for these skills. Let Geng Yong go back and figure out how to fire a layer of enamel glaze on the surface of the iron sheet.

The purpose of Liu Bei's construction of "water pressure" is naturally related to armor.

That's right, behind the enamel nail sheet, there is a gasket made of finely woven into a net with hemp silk, then applied layer by layer of beef glue, and then pressed from a stone pier. This "multi-layer fiber gasket" will form the powerful defense of the enamel nail sheet together with the enamel nail sheet.

There are enamel armor pieces in front and multi-layer thread gaskets on the back. Such armor made of more than 650 composite armor pieces can protect against swords, bows and crossbows!

Although the thickness of the iron sheet was reduced, Liu Bei roughly estimated that the entire set of enamel armor still weighed 60 kilograms!

Non-relius can wear it.

This is also the reason why Liu Bei asked Huang Zhong to select the division based on the specifications of Wei Wuzhang.

When he heard that Liu Bei was going to make a letter armor, the old patriarch cleared out the newly arranged ancestral temple and sent a good craftsman in the clan to shut down the news.

The backyard of the ancestral hall had a wall. The old clan leader ordered people to build three walls, build two corner towers, and patrol day and night to prepare for trouble.

Huang Zhong was good at using big swords. All the trains he had inscribed were sword techniques and shooting techniques. However, the conditions were too harsh, and no ten people were recorded. Only a few people in the Liu family in Lousang were selected. Liu Bei's subordinate Liu Wu was one of them.

If you don’t want to lower the conditions, you can only expand the scope and choose the best among the people who are attached to you.

Only more than thirty people were selected in this way.

More than thirty people were enough to protect Lou Sang.

This made Huang Zhong form a team and train every day.
