Chen Mu's plan to join the compilation of the book once made Zou Zhixian extremely frightened.

To be honest, it's okay to support Zhao Shizhen, anyway, their status is almost the same, and they are all big people who say the same thing outside the military yamen, turn their hands into clouds and cover their hands for rain, and they are amazing.

When you enter the gate of the Yamen of the Oriental Military Palace, don't underestimate the two toes with big toes, maybe who is a little longer.

But Chen Mu jumped out of the wrong way, where are you Dongyang handsome? What are you playing with our toetoe brothers, and I'll stay on top of you.

What the? Do you think the 'upper' refers to the shoulders or the head?

No, no, no, Chen Mu is the sun, and he will roast everyone else to death!

No, Secretary Zhao originally planned to spend more than ten days concentrating on compiling a "Water Pressure Book", talking about the benefits of the water machine, and then investing in the practice of manufacturing water pumps, but Chen Mu patted his head and decided to join in a tea time to shoot the design of the hand pressure water pump to Zou Yuanbiao.

On the way to the Ordnance Bureau, the soldiers had already rushed to the sawmill, the Tun Iron Depot and other places to collect craftsmen and materials, and they went directly to work in the past.

The carpenters held the tools for more than half an hour, took out a miniature version of the hand-pressed water pump model according to the design drawing, and slammed it on the clay pot.

Well, you can't make it!

Zou Yuanbiao and Zhao Shizhen simply applauded Chen Mu's operation!

The servants thought that the Ordnance Bureau was too hot, so they went back to the house and went into the yamen to continue pondering, and pondered until the evening, and it was both drawing and writing theory, after all, the hand pressure pump was relatively complex and novel compared to the current composition and production experience, Chen Mu only knew the general principle, and mistakes were inevitable.

But what is certain is to give him some time, and he can definitely make it again, after all, Beiyang has made it.

When it was dark, the soldiers at the gate of the yamen came to report that there were two craftsmen from the Ordnance Bureau at the door, who had stood all afternoon and did not dare to come in.

When the craftsman was recruited, the two of them carried a large water hammer, saying that the structure of the hand-pressed water pump was complicated, and there were dozens of parts in it.

The groundwater around Changsheng is quite high, it is better to use this, it is simple to make, quick to use, conducive to large-scale production, as long as the structure of the well is slightly changed, the people of hundreds of villages can do it themselves in the future, and it can also be used as a weapon in wartime.

"Weapons?"

Zou Yuanbiao looked at the water gun and couldn't speak, but Zhao Shizhen looked left and right with the water gun, and asked the craftsman: "This water gun is similar to the structure of the gun mouth on the fierce fire oil tank?" ”

In fact, the water pistol is a bit like a large wooden needle, and there is also a piston in it, but it is not rubber, it is a bamboo tube and cooked skin that is a little smaller than the shell, and the Forbidden City uses this thing to extinguish the fire, and the two eunuchs operate to absorb water from the tank and spray it on the eaves of the seven-zhang high.

The accurate name of this structure should be called the pump, this name comes from Yu Zhenmu's "Tree Planting Book" in the twelfth year of Hongwu, and the reciprocating, piston, and pump-action means the same, and later the pump-action shotgun is also called the pump-type shotgun.

The people take food as the sky, once the ancient China found that the technology is very advanced, it will be able to find its roots from agricultural production, the first use of the pump for agricultural irrigation, the piston inside is the same, but not irrigation, but from the salt well to draw salt water.

Su Shi of the Northern Song Dynasty's "Dongpo Zhilin" wrote: and the difference between bamboo is small, in and out of the well for the bucket, bottomless and know-it, hanging ripe skin a few inches, in and out of the water, the air from the breath and open and close, a tube to water several buckets, all the tube wells are machine, where the benefits are, people know.

Chen Mu was very interested when he heard Zhao Shizhen say that the structure of the water gun and the fierce fire oil tank were almost the same, and under the surprised eyes of the two craftsmen, he asked the soldiers to lift the big water gun to the table, and then he saw the Oriental marshal surprised one after another, moving like a child.

For a moment: "Eh, this is amazing! After a while, he said: "It can still be like this!" ”

Zhao Shizhen was surprised by this kind of behavior, and asked, "Dashuai, haven't you used a fierce fire oil tank in Nanyang?" It's like I've never seen this. ”

Chen Mu's demeanor was indeed quite like something he had never seen before, but he replied very naturally: "I've seen it, I've used it twice myself, but I didn't carefully study the structure in it at that time...... At that time, I was still a thousand households in Xiangshan, and I didn't think this thing was easy to use. ”

"I am young, I have no experience in commanding fleets and legions, the army lacks artillery, and I am also superstitious about firepower."

Chen Mu made a small summary of his half-life Rongma, nodded and said: "In the South Seas, three or five ships are equipped with one hundred and ten cannons, even if it is a Franco, it is enough to be vertical and horizontal, mainly good at combat thinking, others want to fight with you, let's run and shoot cannons, who can win?" ”

"At that time, it is useless to develop more fierce fire oil tanks, unless I want to hit people, no one can get close to my ship within ten feet, and it is difficult for fire oil tanks to work."

Chen Mu said while struggling to pick up the water gun designed for two people to use, and his thoughts were already flying after his hand stroked the gun: "The whole should be smaller, a little more portable, the front end is designed to be tapered, increase the jet pressure, the middle of the two-foot-long bamboo tube is opened, and five are connected and carried behind the back, which can be carried by one person...... Well? ”

What shocked Chen Mu was a strange cry in Zou Yuanbiao's applause.

"Okay, handsome!"

Zou Bald had already figured out that the correct way to use this thing was to make it bigger, erect it on the well, and then dig a slope along the edge of the well on the other side, draw water and cross it down the slope, and spew out the water.

Although it is a little difficult to make, in fact, it is not difficult to go anywhere, but it can save a lot of effort for fetching water, and the villages under his rule need this, especially the little thing that Chen Mu said.

"Under Chang Sheng's rule, every village has to dig a few wells, put a few big pumps, and then match the farmers with what you said, five water cylinders are not enough, at least a family of three or four with twenty water cylinders, or directly let the donkey pull the cart, put a big bucket on the car, a little higher, with a leather pipe connected to the water gun, no longer have to worry about watering the ground!"

"You don't know how uncomfortable it is for farmers to bend over and hand over water, and the vegetable farmers are holding small water scoops and watering them one by one...... Well? ”

Before Zou Yuanbiao finished speaking, he was gently pushed by Zhao Shizhen with his elbow, and when he looked up and saw Chen Mu who was stunned, when he turned his head to look at Zhao Shizhen in confusion, the expression of the small unit was extremely strange.

Zhao Shizhen pursed his lips very seriously, looked at the water gun on the table with his eyes, and said softly word by word: "Dashuai is not good, I mean Dashuai is not as sympathetic to the difficulties of people's livelihood as you, his tone, expression, and action just now are probably not designing farm tools." ”

Zhao Shizhen, who deals with weapons all day long, and even designs a few weapons himself, knows Chen Mu's thoughts very well, and he guesses that what Chen Mu puts in the five-link bamboo tube in his mouth is definitely not water, and the biggest possibility is fire oil.

If it is really fire oil, then Zhao Shizhen guessed that there may be another detachable fire source on the water gun mouth to ignite the fire oil.

Thinking of this, Zhao Shizhen grabbed the cuff of his right hand with his left hand, and stretched out his right palm to slap it on the table.

"Dashuai I think about it, a hundred households with two, a thousand households with twenty-four donkeys, twelve pull two catties of artillery and shells, the other twelve pull weapons, each head can carry two sets of twelve magic arrows, carrying a small car can hold two cans of oil, the most fierce in the world is fire, take the meaning of ten thousand invincible, the name is Mo Enemy Gong!"

Chen Mu was shocked: "Why are you two thinking so far?" ”
