Zhang Shengde was very surprised that he really asked for himself.

Zhang Hao said calmly: "The heat is not enough, and you have to press it."

I asked my dad to come forward and said that things were too hasty and we weren't ready yet.

In short, give them hope and let them know that we have the ability to solve this problem, and that we are willing to help them 'without expecting anything in return'.

But we also need to let them understand that it is really inconvenient for us to come forward now, because we lack the 'identity' to come forward. ”

Zhang Shengde nodded slightly.

It's hard to say this, Zhang Hao was afraid that he would not be able to grasp it, so he asked Zhang Shengde to come forward. And in terms of identity, Zhang Shengde is the representative of the Zhang family.

Zhang Shengde didn't have as many worries as Zhang Hao, came to the door, and shouted loudly: "Ladies and gentlemen, I apologize for the problems you encountered, and I didn't expect things to be like this."

Anyway, this matter started because of the Zhang family, and the Zhang family will also be responsible for solving it, and will definitely give everyone an explanation.

But for the time being, I don't have a clue how to deal with it.

Please give me a moment, okay?"

As soon as I heard Zhang Mingde say this, someone immediately became anxious: "Master Zhang, I'm afraid we won't last long." This man eats horses, but it's not a small number. ”

"yes, yes. Master Zhang, you can do it, can't you solve it quickly? ”

Everyone was excited for a while, and the tone was even a little unkind.

Zhang Shengde's brows furrowed slightly, and he suddenly agreed with Zhang Hao's point of view - the heat is not enough. Is this your attitude of begging?

Thinking of this, Zhang Shengde suddenly snorted coldly: "Everyone, when we first disclosed the Water Forging Technique, it was very clear that we didn't have any requirements.

I can't use this to ask the rest of the family, the firm, etc. to change.

Now, I haven't figured out what kind of identity or what kind of reason to use to discuss with them.

So, please give me a moment.

I still have something to do, so I'll leave first.

Leave. ”

With that, turn around and leave. Someone tried to catch up, but was stopped by the guards.

Seeing the Zhang family's carriage gradually moving away, everyone's excitement gradually stabilized.

Then, someone suddenly beat his thigh in annoyance, and his tone was too excited just now.

The carriage creaked and left Fang City, left the county seat, and walked towards Changshan Town, where Zhang's family was located. In front of and behind the convoy, there were mercenaries hired by Zhang Shengde. This time, the Zhang family transported too many materials, and they had to hire mercenaries.

Fortunately, the road was safe, Zhang Hao returned home, and went to check the progress of Huang Mingshan and others as soon as possible.

Two days have passed, and what is shown in front of Zhang Hao is a gratifying result.

In just two days, under the supervision of Zhang Shengye, under the guidance of Huang Mingshan and other seven people, and with the efforts of the five production teams of Zhao Baishi, Wang Xuhe, Li Mingfeng, He Zhengjie and Bai Xiaodong, a full 50 fans were produced in one go.

And now, Huang Mingshan and seven others are designing and calculating the second-generation wind turbine.

Zhang Hao sat on the podium and quietly watched the seven people of Huang Mingshan seriously busy.

The reasonable combination of mathematics and technology can barely be regarded as an introduction to science.

After a while, Huang Mingshan put down his work and reported to Zhang Hao that some problems were found in the operation of the first generation of fans, and detailed calculations were made, and now they need to be improved.

Zhang Hao nodded, encouraged and rewarded Huang Mingshan and the others, and then began the next step of teaching.

Mathematics began to become more complex, multi-solution equations began to appear, algebra, geometry, etc., as well as basic physical knowledge, new units, density of matter, and so on.

At the same time, these new units are also spreading within the Zhang family.

Hours, meters, kilograms, density, various localized mathematical symbols, etc., have gradually gained recognition, and promoted the Zhang family to move rapidly towards the threshold of industrialization, and the door of science and technology has opened little by little.

Among them, there are also a few small stories, Zhang Hao came up with a lot of strange tricks in order to make some units more reasonable.

Because an hour is only half an hour, it is called a 'small' hour. Then divide 'minutes' and 'seconds'. Fortunately, the concept of 'minutes and seconds' exists locally, but the measurement is different, Zhang Hao only needs to borrow it and standardize it.

When introducing the unit and concept of 'rice', Zhang Hao was eating rice, so he pointed to the rice and said: "Let's use 'rice' as a new unit; rice is indispensable for three meals a day, and 'rice' is really too important."

As for the concept of 'kilogram', it is also related to rice, Zhang Hao deliberately selected some large and full spiritual rice, weighed one kilogram, and then asked everyone to count the rice grains, almost more than 1,000 grains. So, Zhang Hao said: One kilogram is a thousand grains of rice, the word 'grain' is not appropriate, let's use 'gram' instead, mainly because there are few strokes.

As for acceleration, pressure, etc., for the time being, they are not replaced by simplified symbols, but are directly replaced by 'm/s²' and 'g/m²', and will be developed as needed in the future.

In short, because the pace of the Eastern Crusade was approaching, Zhang Hao had to find ways to speed up the industrialization of the Zhang family, even if there were some means, it sounded ridiculous.

Before I knew it, it took another five days for the second-generation fan to be put into operation. The new fans are smaller and more efficient.

When a fan replaced the traditional bellows and craftsmen, Zhang Shengde and Zhang Shengye also felt the power of industry.

The scale of Zhangjia's Xuaniron smelting is becoming more and more ambitious, and ordinary bellows can no longer meet the needs of smelting. With the completion of the production of the second-generation fan, the old bellows can no longer be seen on the Zhangjia Xuaniron smelting production line.

As for the first generation of fans, they were gradually withdrawn, and then ...... Thrown into molten iron and melted.

Technology will never be passed on. At least for the time being.

In the production process of the fan, the specially approved 'Bai Xiaodong' and his production team gradually shined brightly, and the assembly-line production method was finally born under the guidance of Zhang Hao.

Zhang Hao, Zhang Shengde, and Zhang Shengye personally supervised the first fan production line put into operation. Under the leadership of Bai Xiaodong, the production team has increased to 30 people, and they are busy in an orderly manner, producing at a rate of 4 to 5 fans per hour.

The new assembly line production method has gradually shown strong vitality.

However, Zhao Baishi, Wang Xuhe, Li Mingfeng, and He Zhengjie were not far behind, and they also began to study new production methods under the guidance of Zhang Hao.

The idea and mechanism of competition gradually germinated within the Zhang family.

Young people, see new hope. Under Zhang Hao's intentional guidance, everyone began to learn to observe the world with a rational eye and study everything around them.

An atmosphere of learning and research is brewing here.

Today, Zhang Hao once again took out the "Sutra of Calculation" and said to the seven people of Huang Mingshan: "Everyone, the second-generation fan is running well. But we should not be satisfied with a fan, a fan that can only blow air.

I needed a brand new fan, or not a fan, but a machine that could output power.

We want to use this kind of machine to replace the people who pull the mill, and even replace the people who work hard. We need to replace the hard work with machines and leave the easy work to everyone. ”

In the distance, craftsmen shouted slogans and were engaged in heavy work.

Mining, transporting, crushing, pouring......

All of them require heavy physical effort from craftsmen.

The eyes of the seven people of Huang Mingshan gradually brightened, and they found meaning!

(Note: Since the starting point does not support formula input for the time being, it can only be expressed in "meters/square seconds", which is the unit of acceleration m/s^2.) ）
