After seeing off Bi Gou, Zhang Qian immediately devoted all his thoughts to the improvement of the windmill.

He needed to come up with a brand new design, cheap windmill well consortium before Bitu left, instead of the current money-burning machine that costs at least three hundred cranes per aircraft.

Now this kind of money-burning machine with bronze as the movement and cooked iron as the skeleton is suitable for him. Zhang Ruoxu and Sun Anzu "taught out" their own farms, but it is not suitable for Bi Gou to promote it in a place of exile.

Nowadays, this kind of money-burning machine is precise and solid, but it is not something that ordinary people can afford. According to Zhang Qian’s understanding of the Tang Dynasty, even ordinary people are very troublesome to spend twenty yuan at once. Therefore, it is impossible for anyone to spend the savings of his generations to relieve floods for the whole village!

Therefore, if you want to promote windmills and wells, the accuracy can be reduced, the durability can be reduced, and even the performance can be reduced, but the overall cost must be low!

It is best to be as low as the ordinary little landlords in the Tang Dynasty who can afford to grit their teeth, so that this thing can be promoted on a large scale! Only when Bi Gou left Chang'an can he leave without regrets.

"Senior brother, this is too difficult. I want to use it well and spend less money. How can such a good thing be done in the world?!" Guo Nu was very confused about Zhang Qian's thoughts and grinned and poured cold water on him.

"Senior brother, if you have that time, why do you think about how we can expand our shares for Liushen Commercial Bank. At present, Wang Yuanbao is asking, the housekeepers of Duke Bao, Kui Duke's Mansion and Duke's Mansion are also asking." Ren Cong hopes to change his direction and find another way, "As long as the second round of stock expansion is over, you will give Senior Bi ten sets of water trucks and wells for free, which is a trivial matter!"

"Don't forget that our Qin Mo is also a branch of the Mo family. The ancestor made various utensils in the past to benefit the world!" Zhang Qian always attached great importance to the two junior brothers' ideas, but this time, he chose to be stubborn. "If an utensil is made and ordinary people cannot afford it, wouldn't we be ashamed of the ancestors?!"

"As for the second round of stock expansion and dealing with people, it is not the best thing for senior brothers. You two are just doing it." You deliberately did not look at Guo Nu and Ren Cong grinning. After thinking about it, he continued to add, "In the end, as long as we can guarantee that the combined capital of our three holdings will be no less than 51%. Even if you two let go, you will still be the previous sentence, the Six Gods Business Company is the foundation of our existence. At this moment, we can attract more strength to participate, and the more stable we will walk in the future."

"Yes! Senior brother!" Guo Nu and Ren Cong had no courage to refuse, so they had to bite the bullet and bow to take the order.

Seeing that the two were in the bottom of the two, Zhang Qian smiled again and whispered to encourage them, "Don't worry, the development and growth of the business can be slowed down a little, and everything is mainly focused on stability. Although the three of us are all "green budgies", ordinary officials no longer dare to come to the door, and the others do not know the real cost of flower dew. There is no need to interfere with the refining of alcohol for a mere dozens of tons of profit!" (Green budgies, the self-deprecating statement of the eighth-rank and ninth-rank officials in the Tang Dynasty.)

This is a big truth, and it is also the main reason why he dares to "waste" most of his energy on the improvement of the "windmill and well set".

At present, although he is only a senior eighth-rank chief clerk, local officials of the county magistrate and county magistrate have no courage to come to him to force him to buy shares.

The emperor named alcohol "Gunpowder" and ordered the opening of a gunpowder office in the Ordnance Supervision Bureau to some extent, which has represented the royal family's emphasis on "gunpowder". Without understanding the real cost of the flower water, the top powerful people in the Tang Dynasty would never deliberately "apply to the emperor" for a small business that only cost dozens of profits per month. Although, although the Tang emperor's presence was extremely low, he was far inferior to his wife, daughter and brother-in-law!

Therefore, taking advantage of this rare peace period, Zhang Qian wanted to do something he liked.

Whether it is out of respect for Bi Gou himself or his kindness to the people of the Tang Dynasty, it is worth his full efforts.

He is just an eighth-grade "green parrot", and he is not qualified to participate in the court's discussions, nor has the ability to intervene in political disputes. However, he can make Bi Gou have more expectations for the future when he leaves Chang'an.

But he can, with his own ability, let the people of the Tang Dynasty suffer less from floods and eat more meals of corn and sorghum.

In a sense, this was also his return to the Tang Dynasty. After all, this world accepted him, Zhang Qian, and allowed him to live a more comfortable life than in the original world. Although, here, he occasionally felt alone.

"Senior Brother, then I and the second brother will go to the company to expand the stock. Don't worry about alcohol refining. With us here, there will definitely be no problem! You are not too tired. After all, you are the eighth-rank chief clerk, and some things can be handed over to the craftsmen below!"

"Senior Brother, my junior brother is right. If you don't mind spreading the knowledge of the masters and want to make both the windmills and the wells cheaper, why not ask the craftsmen of the Arsenal Supervision for help? Also, the craftsmen of the prison are idle every day. Seeing that we are white, we drooled in greed!"

Seeing that Liushen Commercial Bank's stock expansion was destined to be handed over to him. Guo Nu and Ren Cong couldn't help but start to give advice to Zhang Qian again while "receiving their fate".

The two of them just said casually, but Zhang Qian's eyes instantly emitted a fierce light.

"Leave it to the craftsmen in the military weapon supervisor? Then I will pull the general as the supervisor? Yes, why don't I pull them?! I'm so stupid! I won't use such good conditions!" He slapped his head suddenly, and he rushed straight to the desk. He spread a roll of mulberry paper, picked up a charcoal pen, and his right hand flew and flew.

The so-called awakening of a person in the dream is nothing more than this.

Reducing the manufacturing cost of windmills and wells is a huge challenge for Zhang Qian personally, and it is no different from redeveloping another new machine combination. However, if this matter is regarded as a scientific research project, the project is divided into several sub-items, and then the craftsmen of the military weapon supervisors work together to solve the problem, the difficulty will be much lower immediately!

The military weapon culprits of the Tang Dynasty and the generals next to the military weapon culprits have almost gathered the most skilled craftsmen in the world. Since ancient times, the skilled craftsmen in each prison have the tradition of doing private work outside. As long as they can complete the tasks on time, the fourth-grade official halls in each prison have no intention of causing trouble for a group of craftsmen.

There is no need to keep such a group of craftsmen of the "national treasure" level, but they are just thinking about it by themselves. If they are not stupid, what is it? Compared with later generations, the current Tang army weapon stewards and skilled craftsmen who are serving as supervisors have lower wage requirements to the point where they can be ignored. Each person has a bottle of Liushen Flower Dew and two jars of white chrysanthemums, which is enough to make them forget to eat and sleep!

So, the day before, after the initial split of the "project" in the study, the next day, Zhang Qian rushed to the Military Arts Supervision Gunpowder Bureau with a large stack of drawings.

So, after the next morning, all the famous craftsmen in the military weapon prison and those who were "easy to talk" next door became Zhang Zhubu's targets for advice.

Therefore, under the joint "tactic research" between the military weapon supervisor and the general supervisor of the Tang Dynasty, the research and development of the Zhang windmill and the wells was advanced at a speed visible to the naked eye.

The cost of windmills and wells has been reduced again and again. As the overall cost has fallen to about 60 chutes, less than one-fifth of the original one. If Zhang Qian had not insisted that the components of the entire transmission system were made of metal, the cost could even be doubled to reach the standard of thirty chutes.

"Thank you for yourselves!" When Zhang Qian personally delivered the final design plan and a miniature windmill well model to Bi Mansion by carriage, Bi Gou, who had been demoted to the Sima of Liuzhou, personally opened the main door to welcome the distinguished guests.

These days, because he offended Empress Wei and the Separate Officials of the All-Ship-Emperor, except for He Zhizhang, Zhang Shuo and other old friends, the rest of his colleagues and old friends were like hiding from the plague and avoiding him. For fear that he would be regarded as his accomplice and suffer from the disaster.

Zhang Qian had just heard a few words of encouragement from him, but he always treated him as an elder. He even kept thinking about fulfilling his promise and gave him the model of the windmill well and the latest drawings before he left Chang'an. How could he not be moved?

However, he has now become a "green budgie" and cannot give anything to repay Zhang Qian's kindness. Therefore, opening the main door to welcome guests is the best way to express gratitude.

This move not only represents his personal opinion, Bi Gou, as he regarded Zhang Qian as a close friend like He Zhizhang. It also represents the attitude of the scholars in the Tang Dynasty toward Qin Mo's resurrection.

Of course, Bigou will not pronounce these kindness and profound meanings expressed by actions. However, in the Tang Dynasty, many things that are not pronounced can attract more attention.
