The rain was getting heavier and heavier. Wang Ge sat on a pile of cattail grass and began to make the first item for this exam: a pump.

That is, a fire extinguisher.

The simplest pump has the same principle as a syringe. It has a sleeve on the outside and a pulling rod on the inside. Tie the pulling rod with reeds as resistance and pull it back and forth to suck water into the sleeve. Then push the pulling rod to spray the water out.

Wang Ge quickly finished the simple pump. There were puddles around it, and she played with it a few times. Next, she would imitate the bronze "water gun type pump" she saw in the Palace Museum in her previous life.

A bamboo fire water gun. The principle is the same as the simple version just now, which uses the difference in atmospheric pressure to absorb water.

This kind of blunderbuss needs to be used with a water cylinder. The pump is placed upright in the water cylinder. By pulling, the water enters the inner cavity of the casing from the bottom. Then the sleeve is pressed down, and the water in the inner cavity is forced by the pressure.

, ejected from the top, it can extinguish fires at a height of about nine feet (at this time, one foot is about 2.42 meters).

Unfortunately, the water in the surrounding puddles was too shallow to test. After it was completed, it could only be set aside.

From now on, Wang Ge will start making the second item: coir raincoat. It is also called "coir raincoat", and it was not called coir raincoat until hundreds of years later.

Although Examiner Zheng reminded her to make more clever things, what if it was just casual talk or deception?

The Jin Dynasty was different from previous generations. In the previous generation, the people lived a prosperous life and the production technology was advanced. The skills and products that the craftsmen were proud of were all replaced by various assembly lines and cheap materials. As a result, the traditional craftsmanship was useless and the inheritance was gradually lost.

In today's Jin Dynasty, production technology is in the hands of the imperial court and the powerful. The people at the bottom are in urgent need of daily utensils and agricultural tools, so they can only make them themselves.

In the previous life, there were even fewer craftsmen making coir raincoats than the craftsmen!

At that time, Wang Nanxing went to the Yimeng Mountain area to learn from an elderly and simple craftsman. When she made the first piece alone, it took a full half a month. Later, she posted it to her WeChat Moments, where she was admired and liked.

There were so many of them, but no one thought about buying them, not even asking about the price.

With sufficient materials, she chose coir raincoat and reed poles to make this coir raincoat.

The first step of making a coir raincoat starts from the collar. Wang Ge first tied a hemp rope between the two bamboo stalks supporting the oilcloth shed, and then tied a strand of thatch and another thatch on the rope. Each time he added a strand of grass,

, all must be continued from the bottom of the hemp rope and turned upward. After each knot is tied, it must be pressed evenly and tightened to make the arrangement of the collar locks compact and neat.

The second step is to add locks, which is the main body of the coir raincoat. In this step, the nearly a thousand locks must be arranged in horizontal rows and vertical columns. If the craftsmanship is unfamiliar, it will take at least ten and a half days to weave.

The summer rain continued for two days.

The rain stopped in the afternoon, and the bright sun jumped out of the clouds, shining a rainbow in the eastern sky.

Boom!

"It's not as good as a drum" was beating in a hurry, and the examiners came to inspect despite the rain. As Wang Ge expected, Examiner Zheng took away both pumps.

"Water-boosting tube?" Magistrate Huan thought that the simple version looked similar to the "cracking horn" used to make mud balls, but why didn't he expect that it could also water-boosting?

Magistrate Huan looked at the long water tube again, and ordered the secretary to put the tube upright in the water tank according to the usage method described by Wang Ge.

Then, Shi Shi held the barrel, and Magistrate Huan personally pulled the upper sleeve.

Chi!

The lift is at least eight feet!

The two of them were confused!

Huan Zhen's voice sounded from behind: "Uncle Clan, what is this?"

Magistrate Huan County saw his nephew holding a pile of brochures and asked first, "Has everything been written clearly?"

"yes."

"This is the water tube."

"I thought it was for putting out fires."

Magistrate Huan and Shi Shi looked at each other, and the thoughts in their minds immediately expanded to a new realm! Yes, what is the use of raising water no matter how high or far it is? To start a water fight? But when used to extinguish fires, it is of no ordinary significance.

Got it!

"Yes, it's just for putting out fires." Magistrate Huan smiled.

Shi Shi took the slip and said goodbye.

Magistrate Huan asked: "How is Shizhi's recovery from his injury going?"

"Uncle Xie Clan showed mercy, and he is also very easy to use."

"Hmm. Are you planning to run away again?"

"He doesn't dare anymore."

"Oh!"

"My nephew doesn't dare anymore."

"Don't dare be the best! The trouble you caused this time is, to put it more serious, a violation of national law! Fortunately, you are young, otherwise it would not have been solved with twenty sticks."

"But Jiangcheng is no better than a beast and deserves to die!"

"There are so many damn people in the world! Are they all like you, picking up a butcher's knife and killing them at will? Who knows if there is a devil in your heart? Who will judge whether you have public power and private use?"

Huan Zhen pursed his lips tightly and said nothing.

"I know you think my clan uncle is too busy. In a few days, your father's letter should arrive. If you want to stay here then, I won't let you stay!"

"Where's Wang Tian? I want to see him."

Magistrate Huan ignored him, picked up the small water bottle, pumped water, pumped water, pumped water, pumped water.

"Uncle Clan."

Magistrate Huan still didn't speak.

"Uncle Clan, I was wrong." Huan Zhen bowed honestly.

Magistrate Huan County said softly "Hmm".

"I also want to play with this little water tube."

"Choose one. Do you want a water bottle or see Wang Tian?"

"Want...a water bottle."

In Qinghe Village, Wang Tian was thrown into a carriage by five big and three thick men and sped away.

"Stop! I want to see my brother Huan! Let me see my brother Huan before I go with you!" Wang Tian yelled, his voice broke. The most ferocious song sent from his father.

It seems that he will definitely suffer a big disaster when he returns to Shanyin County (where Shanyin County is the seat of Kuaiji County)!

Sigh, how would he feel if he knew that Huan Zhen gave up seeing him just for a water bottle.

May 17th. The craftsman competition in Cuiyi County comes to the last stage. One hundred and sixty-five craftsmen participated this time, and 100 people were selected to be the craftsmen of Cuiyi County this year.

Wang Ge’s ingredients are all except cattails.

Then make a cattail mat. Since Examiner Zheng likes ingenious things, she first used the remaining bamboo scraps to make some fire folding outer tubes.

In the previous life, Huozhezi only appeared in the Southern and Northern Dynasties - the late Northern Qi Dynasty, using the re-ignition principle of physics. Once you understand this principle, it will be easier to make regardless of the tinder inside or the oxygen-deficient outer tube.

However, the current Jin Dynasty has changed the historical trajectory. Pumpkins have appeared in advance. Will Huozhezi also appear in advance?

Examiner Zheng came over, observed Wang Ge's mat weaving techniques, and secretly admired: This candidate's basic straw weaving skills are indeed top-notch!

It's a pity that the new county magistrate prefers clever things, so he has to force him, the examiner, to tell lies: "Is there only one cattail mat produced here..."

Wang Ge looked nervous and replied: "There are not enough materials, only enough to make one mat."

Examiner Zheng was relieved: Mr. County Magistrate, it’s not that I didn’t scare people, it’s because I didn’t have enough materials.

"Well. Then let's prepare the table well."

"yes."

In order to make up for the fact that he had frightened her in the previous two games, Examiner Zheng warned her kindly: "The floor should not be too messy, and the discarded materials should be collected together."

Wang Ge picked up the outer tubes of the huozhezi one by one and said embarrassedly: "My family is poor, so I use leftover materials to make huozhezi tubes."

"It doesn't matter, it doesn't matter. After the exam, you are allowed to wait...wait...wait! What kind of thing can you make?"
Chapter completed!
