After the mango was planted, the paddy fields of the first season in Lousang Village were planted by the clan and the attached people.

Compared with the manpower of rice planting, the subsequent field management only requires a few veteran farmers who are proficient in farming. Most of the young and able-bodied women returned to the village for civil construction.

Such people eat horses and chew, plus wine, consume a lot of grain. Thanks to Liu Bei's foresight, he asked Geng Yong and Cui Jun to help him buy food a few years ago. Nowadays, the clear stream is so large that it is just trafficked by boat. Unfortunately, there are several silts in the wild forest, and large ships cannot pass.

Liu Bei then took people upstream to dredge the river.

Rotten wood in the river. The good craftsman went into the water to investigate, and said that there was an ancient tree sinking in the water, and the river was crossed. Block the dead wood and broken branches that fall into the river, and become silted up for a long time.

Ancient trees in self-sinking water? It's gloomy wood.

Gloomy wood is also known as ancient sunken wood. It is not deformed, heavy, dense and mothproof, and is comparable to red sandalwood. It can be called the essence of the tree and the soul of the wood. Since ancient times, it has been regarded as a precious wood, a rare thing, and a symbol of dignity and status. It was the first choice for the construction of palaces and coffins for emperors of all generations.

Fortunately, in this era, there are not many taboos.

As long as the sunken wood can be salvaged ashore, Liu Bei can use it for his own use.

How to salvage this thick and long ancient tree, you have to borrow a new tool. Fixed pulley.

Build a cross-river bridge on both banks, put a pulley on the horizontal wood, and tie the hemp rope to the sunken wood by the water good, and the cattle and horses on both sides of the river are manpowered, and they pull out of the water vigorously. Then slowly drag it up to the riverbank.

Su Bo was overjoyed. It is said that this wood can be very useful.

Huang Zhong also came to ask for a branch, saying that he would send it to Nanyang to make a good bow of Yin Wood.

The Yin Wood Bow is also known as the Ebony Bow. The bow of the world.

Liu Bei naturally agreed.

After dredging the river, Cui's merchant ships that could carry 100 stones could go down the river to the Qingxi ferry.

The salted wood of the Liaodong Tian clan can also be transported with the ship, saving a lot of time.

Liu Beisheng was born here and now, and he knew that the northern land used to have a water network and rivers and canals. Instead of a shortage of water, it is necessary to prevent water.

Seeing that the tools were very worn, Liu Bei found the third uncle to build iron tools.

The third uncle said that he wanted to start a blast furnace. Otherwise, the furnace temperature is not enough, and the iron ingot is difficult to refine.

Isn't the blast furnace smoke very big. How many days has Huang Xugang been able to breathe freely, and then he has to hold his breath all day?

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

Huang Zhongyan said, why not use water drainage.

Originally, at the beginning of the Eastern Han Dynasty, Nanyang Taishou Du Shi invented water discharge (hydraulic blast furnace), using the river water impulse to rotate the machinery to make the blast skin bladder expand and shrink, add oxygen to the furnace, and increase the furnace temperature. "If you exert less effort and see more work, the people will do it." The invention of water drainage is a great progress in smelting technology.

In this era full of surprises, how can people not love it.

Immediately, the third uncle's blacksmith shop built at home was moved to a steep slope downstream of Qingxi.

After the water drain was built, Liu Bei went over to take a look. I saw that in the torrent, there was a wooden wheel. The flowing water rotates the wooden wheel, and the circular movement of the wooden wheel is changed to the reciprocating movement of the row (bellows) up and down through the transmission of the axle and tie rod, so that the leather blower bag is continuously opened and closed to achieve the purpose of air blowing.

This set of devices that turn circular motion into an up-and-down reciprocating motion can be of great use with a slight change.

So Liu Bei built another workshop on the other side of the steep slope. A stone pier is lifted by a torrent and then falls. but not for iron. Instead, it is used to crush hemp mats.

is completely different from making bedding, what Liu Bei wants to make is a piece of armor.

Why do you want to make armor, you need to start from a conversation between Huang Zhong and Liu Bei.

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

Liu Bei blurted out: The armor of the three genera of clothing (heavy armor of the whole body), exercise twelve stone crossbows, take fifty arrows, put them on them, crown with a sword, win three days of food, and go to a hundred miles in the middle of the day (half a day).

Huang Zhongjian's eyebrows jumped: Shaojun wants to choose the martial arts of the Wei family?

Liu Bei smiled and nodded: It was Wei Wushu.

One stone is equal to one hundred and twenty catties (30 kilograms). A crossbow below three stones is an arm tension. A crossbow below eight stones is a stretch. A crossbow of ten to twelve stones is a waist stretch. The bow is about seven stones, and only the waist can open a twelve-stone crossbow. The opening posture is 'sitting, lifting, and pedaling'. Pedal on the crossbow burden, use the waist to pull the crossbow hook and use the hand to pull the crossbow string to shoot, that is to say, it is equivalent to using the strength of the whole body to open the twelve-stone crossbow.

The limit of ordinary people's arm strength is only two stones. Huang Zhong was able to open the bow of three stones in a row.

An arrow shot out from a hundred steps away, like a long rainbow through the sun, actually pierced the bull's-eye!

The audience was silent. Then there was a roar of applause.

Geng Yong, who was accompanying Liu Bei, sighed in his heart again. Lou Sangwu Fort has not yet been built, but it has found such a strong general. Thieves still dare to call?

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

This time is different. Liu Bei actually wanted to burn a layer of porcelain glaze on the rectangular iron sheet.

The style of the rectangular iron plate, Geng Yong recognized at a glance, this is the armor piece of the armor. Liu Bei wants to make armor!

Zajia, also known as Xuantieyi in the Han Dynasty, is a kind of armor with strong defensive power. Materials vary from time to time. In the Shang and Zhou dynasties, it was bronze armor, and after the Han Dynasty, it was mostly iron leaf armor.

According to the different nail pieces, it can be divided into two types: one is a rectangular nail piece. The armor with rectangular armor is divided into two styles, one is made of two armors on the chest and back with belts and shoulders, and the other is also equipped with a shawl, which is more defensive. Both of them are ordinary soldier armor. The second type is the armor made of small fish scale-like armor, which is the armor of generals. The soldier's armor weighs about 44 catties (11 kilograms) and needs to be woven with more than 650 pieces of armor.

But what's the use of burning a layer of enamel?

Liu Bei said with a smile, this is called: enamel.

After burning a layer of porcelain glaze on the surface of the metal armor, it can prevent heavy swords and crossbows from breaking armor. During World War I, the tank was enamel, and the protection was amazing.

Geng Yong will be skeptical.

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

Liu Bei's purpose for building 'water pressure' is naturally also related to armor.

That's right, behind the enamel armor, there is also a mesh finely woven with hemp silk, and then coated with cow glue layer by layer, and then pressed by the stone pier - gasket. This 'multi-layer hemp fiber gasket', together with the enamel armor, will form a powerful defense of the enamel armor.

There are enamel armor pieces in the front, and multi-layer hemp silk gaskets in the back, so that more than 650 pieces of composite armor are composed of armor, which can prevent 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 sixty catties!

Filux cannot wear it.

This is also the reason why Liu Bei asked Huang Zhong to choose the part with the specifications of Wei Wushu.

Hearing that Liu Bei was going to make a carapace, the old patriarch cleaned up the ancestral hall that had just been arranged, and sent the sect people and craftsmen into it to close the news.

There is already a wall in the backyard of the ancestral hall. The old patriarch also ordered people to repair three other walls, build corner towers and double que, and patrol day and night to be prepared.

Huang Zhong shoots and is good at using a big knife. All the recruits are taught by swordsmanship and archery. Unfortunately, the conditions are too harsh, and there is no one in ten entries. Only a few people from the entire Lousang Liu clan were elected. Liu Bei's brother Liu Wu is one of them.

I don't want to lower the conditions, so I can only expand the scope and choose the best among the people.

In this way, only more than 30 people were elected.

To protect Lou Sang, more than 30 people are enough.

This allowed Huang Zhong to form a team and practice every day.

So far, Lousang Village has two teams. One said: the part, and the second said: the martial arts.
