Tang Taizong is my elder brother

Chapter 75 Hydraulic Machine Tools
Everyone looked at me and I looked at you. After thinking for a long time, I finally came to a conclusion: I don't know.

From Yiwu to Dunhuang and then to Shanshan, no one can defend the whole line at a distance of hundreds of miles.If the enemy sets up layers of fortresses for defense or monitoring their own movements.

The pressure on the frontier troops near Dunhuang will be much less, and the opponents have given up the familiar mobile warfare and turned to fixed ground offensive and defensive warfare like bunkers, which is undoubtedly to exploit their weaknesses and avoid their strengths. Are they stupid enough to do this?

Seeing that Changsheng was lost in thought, Qin Qiong ran over and reminded: "My lord, is it too early to think about the enemy's future movements? How can we deal with these people in front of us?"

Chang Sheng slapped his forehead, and he was so angry that he even gave up everything.

She thought for a moment and ordered: "Increase the patrols in this area and closely observe the enemy's movements. Director Fang mobilizes your spies to set up checkpoints along the road from Dunhuang to Shanshan."

"Yes, my lord." After receiving the order, Fang Xuanling went down to assign tasks.

Changsheng returned to the camp and immediately came to find Master Lu.

She inquired about the development of gunpowder and cannons in detail, and asked a question, if a cannon was to be bombarded directly to the stronghold on the opposite bank, what caliber of the cannon would be needed.

"Obviously, according to the blueprint design of your system, sir, we have calculated the combat parameters of the cannon, and the distance of more than 100 meters is completely within the combat radius. It's just..." Master Lu hesitated to look at Changsheng after speaking halfway. , I can’t say anything later.

"Speak directly." Chang Sheng waved his hand.

"We need to make eighteen-pound guns, but we can't make them now..." Master Lu whispered while observing Chang Sheng's expression.

"We must start with the smallest caliber of the one-pound gun. After the one-pound gun experiment is successful, we can slowly increase the caliber, two pounds, three pounds... and then slowly increase."

Chang Sheng took a deep breath and asked, "According to the current speed, how long would it take at least to manufacture the [-]-pound gun?"

Master Lu didn't speak, but held out three fingers.

"Three months?"

"Three years."

"Thank you, goodbye!" Changsheng turned his head and left. Three years later, I can trample the opponent to death with my infantry. What kind of cannon do you want to build?

But there is no way to think about it. This kind of black technology that is long ahead of the times is not so easy to study.

Faced with all kinds of scientific difficulties, if only a cast iron technology has not mastered the blast furnace steelmaking.

They can't even touch the gate of the iron cannon, forget it, don't force them, I'd better think of another way.

……

In April of the fourth year of Daye, the approval documents of the Ministry of War and the Northwest Frontier Army were officially issued, and the recommendations of a large number of officers under Changsheng were officially recognized and approved.

Qin Qiong was awarded the commander of the Dunhuang Guard, and Fang Xuanling and Zhang Baozang were awarded the Commander of the Dunhuang Guard Changsheng Battalion.

In addition, Zhang Hu, Liao Zhong, Xiao Feng and Shi Daqiang were all appointed.

Changsheng's Changsheng Battalion claims to have [-] soldiers, which is more than the quota for a general.

After reconnaissance and cooperation, there are more than 3000 people, and they are treated like a lieutenant in other small places.So he begged for the fifth-rank official status of General Zhonglang for the four of them.

"Humble post, thank you for your promotion."

The four fell to their knees in joy. Two years ago, they were just refugees, and they couldn't even get enough to eat. After a short period of time, they all became generals.

Changsheng smiled and told the four of them to get up quickly.

Gao Ziran also smiled and said, "I also congratulate the four generals."

Everyone was polite again, and waited until the rewards for meritorious deeds were over.

Changsheng discussed the future development plan with everyone.

Now the land area of ​​the Changsheng Camp is [-] mu, which can basically guarantee the balance of income and expenditure.Changsheng's plan is to reclaim another [-] mu. Anyway, the surrounding land will be idle if it is not reclaimed.

If it weren't for the lack of manpower, Changsheng really wanted to reclaim all the nearby ones.

The animal husbandry industry is developing well, and the first batch of sheep exchanged with the East Turks has arrived. Now there are [-] cattle, sheep and horses in the entire camp.

Three thousand chickens, ducks and geese.

All kinds of vegetables and fruits can find the longevity of the seeds so that they can all be planted.

The end of the discussion is to expand production as much as possible, and when the reserves are ready, go to the north, and a large number of Han people will go south.

She had to prepare early.

At the beginning of May, the water conservancy machine tool she had spent several thousand taels of silver to develop was finally completed. She stroked the bed exuding metal light, and the coldness and hardness from her fingertips made an engineering student feel joy from the bottom of her heart.

Later generations of machine tools were invented by Leonardo da Vinci in the [-]th to [-]th centuries, and it was purely because of his hobby.

Changsheng thinks that she does not have da Vinci's evildoer, but she has a reserve of knowledge after time travel, so she makes full use of natural energy, develops a machine, and then uses the machine to produce the machine. This is Changsheng's development and construction of the secondary industry in the future. preliminary planning.

After repeated research and experiments, and after spending hundreds of tons of wrought iron, this big guy was finally born.

This first-generation machine tool is purely handcrafted. Although it is slightly rough, it has the beauty of industrial roughness.

Everyone was very puzzled when they saw her obsessive appearance. After all, Changsheng was very calm most of the time.
So the curious baby Qin Qiong ran over again and asked, "My lord, how many weapons do you plan to make with this?"

The main functions of machine tools in this era are cutting and compression, which can be used for the manufacture of other equipment. For military use, that is the manufacture of weapons and equipment.

When the cast iron plate is fired, the machine tool can directly press it into the prescribed shape.

"Then what is it driven by?" Qin Qiong continued to ask.

"As the name suggests, the hydraulic machine tool uses water." Chang Sheng looked at him like an idiot.

"However, there is only one branch of the Xiyang River near Changshengying, and the river is not so fast in summer. If we want to water the car as early as before, we have to dig canals, um, and build dams to store water..."

Changsheng looked at Qin Qiong, and this was definitely not something he could think of.

Chang Sheng looked at the group of officers behind him, and when the other party saw Chang Sheng looking over, they all turned away.

"Hmph, then fix it, organize manpower, build a reservoir, repair a few more if one is not enough, and there will be more machine tools, lathes and boring machines in the future."

"But my lord, we are short of manpower. We not only have to cultivate but also train. If we go to repair the dams, the other few cannot be guaranteed."

"And there is time to repair the reservoir, and a few pairs of armor have been knocked out by hand."

"Yes, yes." Everyone echoed.

"Does the waterwheel have other uses?" Changsheng stubbornly protested.

"what?"

"Grinding..."
