It has come May 1854.

The Ming Dynasty, which had a land area of ​​more than 30,000 square kilometers, did not have the military strength to develop military force and then started a new round of war.

Before Wu Yan traveled to the world of "The Smiling, Proud Wanderer", the Ming Dynasty had been settled for six months.

After Wu Yan returned, the Ming Dynasty was still in a quiet state for the outside world.

If you don’t develop, you need money to fight.

The 10 million taels of silver that I asked for before was actually a drop in the bucket for the Ming Dynasty, whose land area had exceeded 30,000 square kilometers.

Even after the disarmament, the military pay needed to be taken out every month was more than 400,000 taels of silver. This was just military pay. The soldiers' food, drink, defecation and scattering were a considerable expense. If they really fought, the loss of food, grass and other food was also a lot of money.

In addition, the establishment of training institutions such as the Ming Academy of Sciences also requires food, accommodation and even wages to those students. As well as the preliminary establishment of courts, a considerable monthly salary expenditure is required.

If there were no taxes and lijin support collected from foreign investors, the previous six months would have been able to squander the Ming Dynasty's treasury.

As for why Wu Yan fought so hard with the great powers of various countries before, he even asked for tens of millions of taels of silver ransom, and merchants from various countries also came to do business...

It can only be said that in the eyes of businessmen from various countries, those who have lost money from the Ming Dynasty must also earn back from the Ming Dynasty.

It is really normal to do business while fighting, not to mention that the battle between the Ming Dynasty and the great powers has stopped now.

The lack of money is also one of the reasons why Wu Yan refused to let Ning Zhongze assassinate Hong Xiuquan. Killing someone might make wedding dresses for the Qing court.

As for him to assassinate Emperor Xianfeng himself, it is useless. After killing Emperor Xianfeng, someone will definitely succeed him.

Only when the army is in a hurry and there are enough people to manage it after winning, assassination will be of some use.

"So, I'm going to be a scientist?"

Wu Yan used the Zora character card.

Food is the most important thing for the people, and Wu Yan first looked at the agriculture aspect.

"In 1828, German chemists synthesized urea for the first time by artificial means."

"In 1838, the British made the world's first chemical fertilizer."

"In 1850, the British invented the earliest nitrogen fertilizer."

"In 1909, German talents solved the technical problems of large-scale production of nitrogen fertilizer..."

Looking through some of Zora's memory, Wu Yan decided to study the issue of manufacturing fertilizers first. Compared with the technical environment required for studying Zajia rice, fertilizers are much simpler.

According to relevant statistics, among the various measures to increase agricultural production, the role of fertilizers accounts for 30% of them, which is a very large numerical proportion.

Wu Yan now has too many people who can help him farm. Only a very small number of the Hunan Army that had been laid off before chose to return to their hometowns. In addition to entering the factory, the remaining people have become military camps.

The military farming system is not new in China and does not need to be mentioned too much.

With so many people farming together to reclaim land, Wu Yan occupied the fish and rice town of Jiangnan. If the yield increased by 30%, there was no need to worry about the food and grass issues.

In the Ming Academy of Sciences, Wu Yan led a technical research team to study the fertilizer he named "Jin Ke Tra".

In essence, it is actually nitrogen fertilizer made of urea. For a long time, this fertilizer was the largest fertilizer variety produced and used in the world.

The research process is actually very simple. It’s nothing more than Wu Yan’s statement of one, two, three, four, and five. The people in the technical research team will follow the steps he mentioned and implement them step by step.

"I would have a smart robot."

Wu Yan really hopes that the next time he travels, he can go to a modern world, science fiction world is better. Even in a world without robots, he can create an intelligent robot.

When the robot is brought back to this world, he will not need to do these scientific research work.

"If you look at it this way, Ning Zhong seems to be useless. Although he has become younger and more beautiful, with the Yi Jin and Marrow Cleansing Chapter I taught, his martial arts progress is also very fast. He can constantly harmonize my yin and yang, and help me practice the Nine Yang Divine Art... but it cannot solve any essential problems."

Wu Yan felt a little regretful, but it was just a thought. In the past world, there was indeed no one worth bringing him back except Ning Zhongze.

If the fragments of the Gate of the World are not used, they will expire and be invalid.

It can be considered that chatting is better than nothing.

After half a month, Wu Yan led a team to successfully create the "Jinke Trash" and completed the industrial programming of large-scale production.

He doesn't need to pay attention to the rest. After Jin Ke trash was created, there is a high chance of a bumper harvest in the area under his rule.

The reason why there is a high probability rather than 100% is that farming requires the help of water conservancy projects and is also very dependent on the weather.

Increased grain income is very important. It can not only help the current Ming Kingdom, but also a great help when Wu Yan defeated the Taiping Heavenly Kingdom and the Qing court and competed with the powers of the world with the entire Chinese land as the foundation.

"I said it works, then it must be useful."

Although Jin Kezhe has studied it, some people who know very well about farming have doubts because of the limitations of the times.

At this time, Wu Yan showed his dictatorial side without any hesitation.

"Do not question any decision I made before you have confirmed that it is useless, nor do you disobey me. I call myself before you, which does not mean that you may not regard me as the emperor of the Ming Dynasty, nor does it mean that you may not call me Your Majesty."

Wu Yan's words made all doubts disappear instantly.

After all, he was a Martial Emperor who had killed thousands of people with his own hands, so he still had this majesty.

This is also the benefit of the feudal era. If it were in modern times, many people would definitely be rude to doubt, obstruct, and kill, because there were always some people who felt that they were public intellectuals and were doing good things, and they did not know that they were using their lives to hold back because of the limitations of the times and knowledge level.

Wu Yan studied Jin Kezi for agricultural matters. As for water conservancy projects, he cannot make effective improvements for the time being, so he can only build according to the existing technical level.

"Industry is the top priority."

Wu Yan, who had been in the Ming Academy of Sciences for half a month, did not leave after completing Jin Kezhe. He was going to start the next scientific research.

Before the last time travel, the Ming Dynasty was stable for six months, and Wu Yan also made some preparations during that time.

And now, these preparations are about to come into play.

Wu Yan's first industrial research project was the steam engine.

Although Europe was about to enter the second industrial revolution at this time, the steam engine, the main force that led to the first industrial revolution, has been used in Europe for hundreds of years. But what is very ridiculous is that the entire Chinese land cannot find even a domestic steam engine due to the Qing court, let alone the steam car invented by Europe in 1814 and the miner's lamp invented in 1815.

Although Wu Yan knows how to build oil engines, it is very difficult to extract oil from crude oil before there is enough overall industrial level, let alone other chemical raw materials.

The steam engine can not only help Wu Yan develop industry, but also increase Jin Ke Tradition's production.

Another technical research team. Under Wu Yan's personal guidance, he strictly followed the relevant steps, knew the truth but not the reason, and built the first domestic steam engine of the Ming Dynasty in the true sense, and it was also the first domestic steam engine in Chinese history.

At this time, those involved in this project did not know that they had created history and would be written into the history of the Ming Dynasty and even the world history together with the "greatest inventor of history" Zhao Wuji, the Emperor of the Ming Dynasty.

They were just shocked by the power of the machine.

Steam engines are very backward in modern people, but in fact, this thing was still the most important prime mover in the world in the early 20th century. Wu Yan made the most advanced steam engine in the world, and it can even be said to be the most advanced steam engine, which can be used until fifty years later.

The principle is very simple, which is to use combustible materials such as wood, coal, oil, and natural gas to boil water to generate high-pressure steam, and push the piston to do work.

At this time, there was no oil and it was difficult to utilize natural gas, so it mainly relies on coal with higher combustion power.

In a courtyard of the Ming Academy of Sciences, a metal creature with a very strange shape seemed to everyone in the audience, has been activated.

Someone next to him kept filling in coal to ensure that the water in the boiler always stays boiling and converts it into high-pressure steam.

A circular metal connected to the outside of this steam engine looks like a carriage wheel. Under the action of high-pressure steam and mechanical transmission, it is rotating wildly at a speed that is almost impossible to see with the naked eye.

"Your Majesty, if you put this wheel on the carriage, no, I mean, put this steam...steam engine on the carriage." Hua Tong, the president of the Ming Academy of Sciences next to him, said in a sharp voice: "Will the carriage run so quickly without a horse being pulled?"

Wu Yan glanced at Hua Tong. This man had successfully castrated himself a month ago. After a month of recovery, he also had good medicine and the help of "Sunflower Book". At this time, walking, sitting and lying down was no different from ordinary people.

If we talk about the difference between him and himself, so far, it is just that his voice has changed a little and his temperament is a bit feminine, and he has not yet reached the level of becoming a woman.

"It is indeed the case in theory, but the wheel can turn so fast because it does not suffer serious resistance."

Wu Yan answered.

"resistance?"

The people who had a technical research team next to him expressed their confusion about a new word that appeared in their Majesty, but they also remembered it in their hearts.

"No, resistance."

After Wu Yan explained it briefly, he stopped talking, not because he cherished it himself, but because he said too much, these people couldn't understand it.

Then Wu Yan said: "With this thing, some workshops that require hydraulic power are no longer built in streams or rivers. Water trucks can be gradually eliminated. Whether it is water pumping or water trucks can provide mechanical kinetic energy, steam engines can provide better."

For a long time, water wheels have been an important tool for humans to gain "power". In the farming era, besides water wheels, there were only human and animal power.

This has led to the inability to develop industry.

The steam engine can not only provide more ‘power’, but also ignore the limitations of the terrain.

"There are ships." Wu Yan said: "The iron-armored warships of the Western barbarians use this kind of machine as power. Compared with sails and man-powered paddles, they are far ahead of us. This is also one of the reasons why the Qing court's naval battles could not beat the Western barbarians. Hua Tong, you arrange some shipbuilding masters to find ways to load the steam engine on the ship. As long as the experiment is successful, we will start to build our iron-armored warships."

There are still many talented people in China in such matters as shipbuilding. After Wu Yan solved the core problem of steam engines, the rest did not need to be bothered.

"The steel mills should also use this steam engine as soon as possible, and use the power of machinery to crush the ore, and create transport ore, which can save a lot of manpower and time."

Wu Yan arranged another sentence.

"Your Majesty, what is a conveyor belt?"

The people from the Ministry of Works next to him were very puzzled.

Wu Yan sighed and said, "Look at whether this wheel is turning all the time? Then, if there are two wheels that are separated by a certain distance at the same time, and then you tie a cloth between the two wheels, will the cloth continue to rotate? And when the cloth rotates, will the ore on the cloth be moved as well?"

The people from the Ministry of Works couldn't figure out the picture of the conveyor belt and said blankly: "But your Majesty, this wheel is too small. Even if you made two and wrapped them with cloth on the wheel, you can't bear the weight of iron ore."

"You're not going to make the steam engine bigger and the wheels wider?"

Wu Yan couldn't help but get angry.

Even if he has Zora character cards and has countless technological knowledge that is ahead of this era and modern times, it is impossible for him to build a spacecraft by himself.

"I, the emperor, have to teach you everything myself, or even do it myself. Tell me, am I an emperor or a craftsman in the Ministry of Works?"

When Wu Yan got angry, he fell to his knees. Everyone shouted in horror that he deserved to die, but no one really wanted to die.

I feel so tired.

Wu Yan sighed and said, "Get up for me, Hua Tong, have all the craftsmen who build carriages arrived?"

Hua Tong climbed up from the ground and said, "Your Majesty's words have arrived."
Chapter completed!
