After returning to Beijing, Wang Hongyu has been busy reporting and discussing, and the Ming Dynasty and Ace Duck, the Portuguese Trilateral Trade Alliance and the Military Alliance have basically completed the formulation and improvement of the cooperation charter, which can be sent to the other party.

As for when the other party's cooperation documents will be received, the second round of negotiations and the signing of the alliance agreement will be handed over to Han Jun and the cabinet, Wang Hongyu does not have much time to stay in the capital, and he still has many things to do before leaving.

The aftermath of the battle for the liberation of Baodao was properly handled by the Ministry of War, the Ministry of Households, the Ministry of Industry, and the Baodao Economic and Strategic Government.

Preparations have already begun for the plan to conquer Jiaozhi and Donghu, and preparations are underway for the preparation of materials and the transfer of troops and horses before the battle.

Wang Hongyu took advantage of his precious time in the capital to visit several old friends.

Xu Guangqi plays an important role in China's industrial upgrading and scientific and technological progress.

He was the first pioneer to contact and introduce Western science and technology, and he has always supported Wang Hongyu's science and technology introduction and innovation work.

Wang Hongyu visited Xu Guangqi to discuss the international situation, agriculture and military inventions.

Xu Guangqi praised Wang Hongyu for introducing Deng Yuhan and a group of European scientists through the Holy See missionaries and for setting up an academy to train scientific and technological talents in China, and participated in the introduction of talents and the construction of the academy.

Xu Guangqi studied Western astronomy, calendar, mathematics, surveying and water conservancy under Matteo Ricci earlier, and made great achievements in astronomical calendar and mathematics. He applied mathematics to ten aspects, such as astronomical calendar, water conservancy engineering, music rhythm, art of weapons and military engineering, accounting and financial management, various construction projects, machinery manufacturing, geometric surveying, medicine, and the manufacture of clock leaks.

Xu Guangqi is proficient in agriculture and has written many books, including "The Complete Book of Agricultural Administration", "Sweet Potato Shu", "Agricultural Relics and Miscellaneous Books", "Draft Agricultural Book", "Taixi Water Law" and so on.

Historically, he also wrote various ordinances and codes such as "Selected and Practiced 100 Character Formulas", "Selected and Practiced Rules", "Practicing Art Rules", "Shuwu Rules", "Form and Name Rules", "Fire Attack Strategy", "Gunpowder Making Law" and other regulations and codes, which are a batch of early regulations and codes in modern China.

Now these books are not only still published, but also in advance, because of Wang Hongyu's influence, the content is also more scientific, and it is not completely copied from Western translations.

Every time the two talked, they were inspired by each other's knowledge of science and technology.

Wang Hongyu's future president of the Academy of Sciences is none other than Xu Guangqi, although Xu Guangqi's single science and technology cannot be among the best in the world, but no one in the world has surpassed Xu Guangqi in comprehensive technology.

Wang Zheng also made a trip back to Beijing to Liu Ruoyu's Ordnance Bureau to guide the firearms production line to improve the experience of division of labor and cooperation and the manufacturing methods of new firearms.

He also met with Xu Guangqi to discuss new learning and inventions.

A few years ago, Wang Hongyu and Wang Zheng talked to Zhu Youxiao about the theory and assumption of the steam engine.

"Steam engines? Use the steam from boiling water as the driving force to propel machinery?"

Zhu Youxiao, who has rich experience in invention, understood the core meaning as soon as he heard it. He was extremely gifted in the study of mechanical equipment, and at once he thought of many wonderful uses of steam.

Because the steam engine used water, it was quickly thought of using the steam engine to propel the boat.

There is also coal as a raw material, and now Wang Hongyu and Wei Zhongxian's coal industry is very prosperous, and coal has been standardized and mass-produced, and it can be used for steam engines.

So Wang Hongyu drew a sketch of the steam engine with his memory, wrote out the sketch and the idea and handed it to Wang Zheng to improve, and finally handed it over to Zhu Youxiao to study, Wang Zheng found that Zhu Youxiao's talent in mechanical design and manufacturing was much higher than his own, and he could only help in mechanics.

This time, they jointly visited Zhu Youxiao and found that Zhu Youxiao had already made a steam engine.

Wang Hongyu introduced that Wang Zheng and Tianqi further implemented the improvement and adaptability of the steam engine, and strived to build a steam engine for large warships within a year.

At that time, there will be steam warships, which will be powerful enough to overcome the wind, so that the battleships will be heavier, can be equipped with ironclad and larger caliber guns.

In fact, in the previous life, Wang Zheng researched the steam engine.

However, because of the troubled times and no improvement, the craftsmen were displaced, the social order was chaotic, and finally it became a mirror.

Later, Watt in Europe made a steam engine, which was indeed later than Wang Zheng, but I have to admit that Watt's has been preliminarily available, and Wang Zheng's is a theory and preliminary experiment.

There are no such regrets in this life.

He met Wang Hongyu and met a genius emperor of mechanical engineering.

It seems that Wang Zheng is not the first in inventing the steam engine, but he presided over the construction of the first batch of ordinary practical steam engines. It will not be long before the practical use of a large steam engine will definitely come from his handiwork.

In the future, it will be used for production, railways and waterways for the first time, and the steam age will greatly improve production efficiency and transportation capacity, so we must make Daming the first place to promote steam technology.

Wang Zheng can figure out a lot of technical principles, and although he is not as versatile as Xu Guangqi in terms of new theories, he is more powerful in terms of mechanics and physics.

Zhu Youxiao has innovative ideas and can figure out the principle, although the education is lacking in childhood, but the basic knowledge is quickly improved under Xu Guangqi's teaching.

The two discussed cooperation, and when they started creating, they would not make the identity of the monarch and minister clear.

Gradually, in new school areas such as the Southwest United School, they will be called Mechanics Engineer and Engineer Emperor.

Zhu Youxiao also likes to be called like this.

Sometimes he feels that Wang Hongyu is much more powerful than Xu Guangqi in terms of theories and inventions, and even has no bottom, just because he went out to fight and engage in the economy, he really can't sit down and study.

"When are you not in a hurry to fight, and you can invent and create with the Marquis of Dingyuan?"

He was looking forward to it.

Wang Hongyu is indeed busy.

When he came out of the palace, several guards had already spotted him and hurried up to meet him, and the attendants behind him hurriedly told him:

"The old heavenly official is angry, and sent someone to find you, saying that the marquis has been promoted, and he has forgotten your grandfather, and if you don't visit him again, don't want to see his granddaughter!"

The attendant finished. Several guards grinned, Wang Hongyu felt warm in his heart, Zou Yuanbiao was really straight, and it was too late for others to avoid it, and he was in a hurry to find this popular governor to conquer the governor.

Wang Hongyu suddenly smiled, his family and everything was prosperous, as long as he and Zou Yuanbiao were in one place, there was always a way to deal with others who said that the central minister colluded with the frontier generals.

Now he is the top boss of the frontier and expatriate generals, Zou Yuanbiao is the old heavenly official of the Ministry of Officials, the head of the six Shangshu.

How to deal with it?

The British public has a method, and he has entered the cabinet as an adviser.

First go to the British Mansion to congratulate the British Princess's promotion to the cabinet, and by the way, ask how to avoid suspicion, and the etiquette of courting home.
