I went ashore by weaving straw shoes and became a master craftsman

"It's listening to the urn. I only have a preliminary idea. I'll think about it carefully before I go back and tell Shu Zuo."

In his previous life, Lin Xia not only paid attention to the history before and after the Western Jin Dynasty, but also often checked the changes in weapons and farm tools.Because Wang Nanxing focused on sculpture and learning arts, and spent less time with the forest, and the memory blur caused by time travel, Wang Ge didn't remember much about the evolution of special weapons such as Ting urn.

But it is enough to know about it, and the real thing can be deduced according to the principle.

She wants to listen to the urn instead?No wonder Kong Shuzuo was lost.Since listening to the urn, what has changed is either the size of the urn, or the depth and distance of the shaft. Wang Ge must also start from these three aspects.Alas, today's trip was in vain.The craftsman changed to the urn, and the government would definitely not accept it, because the urn body and the shaft are all the best structures left over from years of actual combat, and they can be taken for granted after just a few glances.

Wang Ge noticed the other party's thoughts, and changed the subject and asked: "Is the soil for the city wall all dug from the God's moat? Will the God's moat be widened and deepened?"

In this era, there was no such thing as "City Moat". The ditch in front of the city wall was called "Pond" if it had water, and "God" if it had no water.

Kong Shuzuo: "That's right. The soil quality is the first thing to look at when choosing a site for a city wall. Soil is taken from the nearest place to build a city. The soil on the surface is dry and can be steamed in the sun. It should be tamped together with sand, lime, and broken pottery. Whether the trench will be deepened or widened later depends on the arrangement of the county office.”

"Is there an improved 'fly bridge' item in the short-term transition assessment?"

"Yes." Must have!If there is no topic, just make up the topic.

The "flying bridge" crosses the ditches, and the "flying river" crosses the river. After the Tang Dynasty, the two kinds of weapons used to obstruct the passage of the flying bridge and the flying river were called "trench bridges".

Wang Ge's face was frozen, and when he smiled, the corners of his mouth were grinning, his face didn't move.The same is true for Kong Shuzuo, his beard is frozen.

Under the city wall, the messy footprints and horseshoe prints are still there, and they are much shallower.

The return trip went smoothly.After returning to the county office, Wang Ge sat by the brazier to warm his hands and feet, while carefully recalling what Linxia mentioned to Tingweng in his previous life.

He mentioned two types of evolution.

One is to change the fixed form of "well listening" to portable "pillow listening".It is made of cow leather, and after blowing air, it is "attached to the ground as a pillow". The principle is "virtual energy accepts sound", and deaf people can hear the movement of people and horses several miles away.

The second is that people listen to the sound outside the urn and change it to the inside of the urn.What Wang Ge couldn't remember clearly was this kind of improvement. How about the "people in the urn" method?Is the mouth of the urn facing up or down?There is no need to change anything in the upward direction, as long as people can get into the urn.If it faces down, piles must be driven in the shaft, otherwise it will not be able to support the body of the urn.But with the mouth of the urn facing down, the body of the urn must not be fully covered by the soil. Will the resonance transmission be weakened?

In Wang Gelai's courtyard, there is an empty urn next to the courtyard door. It is better to see the real thing than just imagine it in your mind. "Ah Xin, turn the urn upside down."

The five little craftsmen were afraid of knocking the pottery urn, so they worked hard together, and put it down slowly first.

"Wait!" Wang Ge sent them away, squatting in front of the downed urn to watch.Thinking of an idea, she called: "Sister Zou... Zhuan, tell the guards for me to find a Taosi. I want a new type of urn."

Mrs. Zou went to the official office with Shu Zuo to inquire about whether there was a county competition for improving the flying bridge in the near future, but she didn't go back to the official office with everyone.

When the lady came over, Wang Ge drew an urn shape on the ground, the top and bottom were flat and sealed, and the opening was on the side.She explained while drawing: "The length and width of the urn are the same as those seen under the city wall today. Note that the opening of the side drum is only enough for one person to get in. Don't open it too big."

As for cowhide, Dajin does not allow cattle to be killed without reason, let alone sell cowhide, and can only be bought from foreign merchants.It's hard to find cowhide in the street market, but there must be some in the market. Forget it, it's snowing too much today, so let's talk about it tomorrow.

Not long after, Mrs. Zou came back.The improved flying bridge is a short-term transfer assessment. Due to the wind and snow and the number of applicants, there is no test tomorrow, and there is only one day session the day after tomorrow and the day after tomorrow.

"Report the day after tomorrow."

If she can get the county head in the ruler-making examination, she will then pass the exam to be the county head of the improved fly bridge, and the conditions of "Hundred Fields County Head" will be fulfilled.

As for the rest of the conditions for a craftsman in Jinzhong... She served as an examiner in the assessment of a craftsman boy, and she completed it in Xiangping; as a "one-year craftsman" is coming soon, her initial contract is counted from July [-]st, Pingzhou is special, half a year can reach another county for a year.

Only the last condition cannot be advanced, she has to go back to Duyi County to be recommended by the county magistrate, the county elder, and a middle craftsman in Kuaiji County, and wait for the approval of the county office.

Don't think too much.For the rest of the time, Wang Ge chiseled a ghostly set of balls next to the brazier, wearing rabbit leather gloves on both hands alternately to keep warm.Don't rush to think about how to improve the flying bridge. It's not because she is arrogant, but because she draws in by analogy. She thought about it when improving the ladder.

In the evening, the snow still showed no sign of stopping. Taking advantage of the light in the sky, Wang Ge moved the city wall molds he brought from Xiangping to the open space beside the west wall of the courtyard. As "Huang Mo".When the interest came, she inserted the house models, cavalry, infantry, and pedestrians into the snow, and sprinkled the soil for the streets.

Mrs. Zou and the others stood around, all in amazement. This was the first time they had seen Wang Ge put together various models. At first glance, it really looked like a miniature city.

The next afternoon the wind and snow died down.

The "Huang's Moat" behind Wang Ge was filled up and the molds were half buried.

The pottery urn could not be fired for a while, and the guards wandered the nearby markets, not to mention that they did not meet any foreign salesmen selling cowhide, and most of the restaurants were closed and not operating.

Mrs. Zhuan was puzzled, pulled Mrs. Zou aside and asked, "Why didn't you mention it to Kong Shuzuo? Can the Gaoxian County Office not even have a piece of leather?"

"Well, yesterday the secretary obviously didn't believe that Age could improve the listening environment, and he didn't say a word, how could Age take the initiative to mention it." Even in Xiangping, it was Wang Ge who tried his own way to prepare sulfur and nitrate, and tested its power. The county office only approved the fire equipment.

"Huh." The truth is the truth, the special lady is still aggrieved for Wang Ge.

In the house, Wang Ge was preparing the timber for the fly bridge.In this exam, she still did not draw any drawings, but only models.With the experience of last time, she engraved the number on each piece of wood in advance, used the tip of a knife to mark the key positions, and compared them with the drawn model one by one, keeping in mind.

That's it.

The fourth day of October.

Wang Ge wore a felt hat, dressed like a fat ball, entered the examination room on time, and did not come early to suffer from the cold.Counting her among the candidates in the room, it happened to reach the minimum number of candidates, 20 people.

The timing drum sounds, Sichu.

To improve a weapon, one must first understand where it is used in war and what function it wants to achieve most.

In fact, flying bridges are seldom used for sieges, but more often used for raids on garrison camps.Because the garrison camp often moves, it can only use bamboo, wood, and horse-repelling equipment as enclosures, and then adopt the method of digging wide ditches outside the enclosure to strengthen the defense.

The functions you want to achieve must, of course, be fast, stable, and easy to transport.
