What kind of gadget is this, it's clearly liquid gold!

For Zhu Mingzhong, who comes from the 21st century, he naturally knows what rubber means and wealth! It means revolution.

It's a revolution in every way.

With rubber, not only can you make a raincoat, so that the army no longer has to worry about marching in the rain, but also can make rubber shoes, so that the hard-soled military boots that are not suitable for the foot army become a thing of the past, of course, more importantly, the carriage, with rubber can make rubber wheels, the performance of inflatable rubber wheels is far better than that of wood and iron wheels, not only to reduce the pressure on the road, but also to speed up.

Rubber!

This humble little thing has changed the world. Once upon a time, in Zhu Mingzhong's planning, in addition to the traditional spices, rice, and cane sugar, rubber will also be the pillar industry of the future Nanyang vassal states in the future industrial planning.

At least in the next two or three hundred years, planting-based agriculture will be the pillar industry of Nanyang, and they will give the Ming a variety of agricultural products, and the vassal states of the Nanyang will not only be a branch of the Chinese civilization, but also the plantation of the Ming Dynasty.

Just when Zhu Mingzhong looked at those rubber seeds and imagined that Nanyang would develop into a plantation of Daming in the next few decades, providing Daming with a variety of agricultural products, Huang Zongxi, who heard that someone had bought a bearing patent at a high price of more than 10,000 taels, came over when he saw the name on the seal.

"Your Majesty'......"

It's Your Majesty!

Although the private seal is "Zhu Mingzhong", who doesn't know that it is the name of His Majesty's submerged residence, although there is a possibility of duplicate names, but when Huang Zongxi came here, he immediately knew that His Majesty was traveling in micro-suits again, which is His Majesty's habit.

Walking to Zhu Mingzhong's side, Huang Zongxi did not reveal his identity, but looked at the rubber seeds in his hand and said.

"Zhu Gongzi is interested in this?"

"Oh, it's Plough Island, yes, if this thing is used well, it will be very versatile, and Plough Island can make people ask Alfonso if there are any species there, and if so, they can be tested in the plantation."

There is a tropical botanical garden in Qinghe Academy, which is a glass greenhouse, and the glass greenhouse of 2,000 square meters is not only for teachers and students to learn about tropical crops, but also for the supply of tropical fruits in Zhongdu. Although the quantity is not large, it can always make the children eat fresh, after all, at this time, it is impossible to transport tropical fruits such as bananas, pineapples, and durians from Nanyang to Zhongdu. In winter, only greenhouses can provide fresh vegetables.

"Oh? It's very versatile"

Huang Zongxi asked with some puzzlement, although he was also quite a learned scholar in the academy, he didn't know much about plants, especially this exotic plant. I was even a little curious about what this does.

"Just this ...... Rubber, of course, is not very useful, but if a special secret recipe is used, it can be used in an extremely wide range of applications. ”

Zhu Mingzhong pretended to be mysterious and said. In fact, the so-called secret recipe is very simple, that is, the rubber and sulfur are evenly mixed in proportion, and then the required rubber can be obtained.

"Your Majesty knows this recipe?"

Looking at His Majesty in surprise, Huang Zongxi's eyes were full of puzzlement, as far as he knew, the plants displayed here were all exotic plants, how could His Majesty know about these?

"Lizhou, why are you here today?"

Looking at Huang Zongxi, who was a little incredulous, Zhu Mingzhong, who realized that he had lost his words, immediately diverted the topic and asked.

"If Zhu Gongzi is interested, you might as well go over and take a look, several students in this academy have made a pumping machine, which is the pumping machine in the mine, today, the owners of several coal mines came to observe, this kind of pumping machine, not only pumping more and faster than ordinary pumping machines, but also it has a magical place......

"Oh? Amazing? ”

This will Zhu Mingzhong is curious, what is it, can be described as a ghostly workmanship.

Zhu Mingzhong, who was aroused by Huang Zongxi's curiosity, went with him to another exhibition hall, and as soon as he entered the exhibition hall, he saw that half of the room was crowded with people, since there were students and businessmen, of course, there were professors of the academy, and in the middle of the house there was an iron object, which was not large in size and looked more like a model.

"Guys, this is the steam pump."

What the!

Steam pumper!

As soon as he entered the room, listening to the words coming from there, Zhu Mingzhong's heart beat suddenly, and he even involuntarily lifted his toes.

Steam pumper!

Isn't it a steam engine?

Or rather, a relatively primitive steam engine!

For a long time, although Zhu Mingzhong had already drawn a simple drawing of a steam engine, it was not manufactured for various reasons, and today, unexpectedly, the students in the academy have made a steam engine, albeit only a pumping machine.

"Steam pumper? What kind of machine is that? ”

A businessman asked curiously.

"The steam pump is a power machine that converts the energy of steam into mechanical work. Compared with the pumping machine in the past, its biggest feature is that it does not need to rely on animal power like an animal-powered pump, nor is it like a hydraulic pump, it needs to be built by the river, as long as there is coal or firewood, there is enough water for him to pump water from the mine at a speed of several times more than the hydraulic pump. ”

Sun Zhongyue, who was standing next to the model of the pumping machine, had a proud look on his face, this was his proudest invention, and he needed to use this invention to tell others that he did not enter the Shu Army by virtue of his status as the nephew of the governor of Northeast China or the son of a loyal martyr, but by virtue of his own talent.

Although he didn't know how important this steam pump was, Sun Zhongyue, as an engineer, knew that this was the first time in human history that human beings had obtained an artificial power in addition to manpower, animal power, water power and wind power. This power is far greater than the world can imagine.

It's a steam engine!

That's right!

It was definitely a steam engine, and when he came to the front, regardless of the surprise of the professors of the academy when they saw him, Zhu Mingzhong looked at the model of this steam engine in surprise, and there was a pressure cooker on the side...... It is the pressure cooker, which is Zhu Mingzhong's invention, in history, he should be more than ten years later, invented by the Frenchman Denis Barpen, but a few years ago, in order to solve the problem of disinfection of surgical instruments, Zhu Mingzhong invented the pressure cooker, since then, the pressure cooker has been used for the disinfection of surgical instruments, and it is also widely used by the Navy - because it cooks meat in a pot, not only saves time, but also even hard bones can be cooked softly. Cooking time is shorter, and the presence of pressure cookers allows naval ships to save more than half of their fuel while sailing, and even fresh water – because steam does not leak out, meaning fresh water can be saved. Although the quantity is limited, it is extremely important for the Navy to save both fuel and fresh water, so that they can carry more food and fresh water in the tonnage saved.

Could it be that he borrowed the pumping machine from the pressure cooker?

"Next to this should be the first year marine pressure cooker, what is it for?"

Unlike ordinary businessmen, Zhu Mingzhong recognized the model of the pressure cooker. Different from the historical Newco gantry machine, the boiler of this pumping machine is independent, and the so-called boiler is a large pressure cooker for ships, at most with some improvements.

When asked like this, Sun Zhongyue, who was about to explain the construction of the steam pumping mechanism, explained.

"Yes, this gentleman has good eyesight, the power of this steam pump is provided by the steam generated by the large pressure cooker, in fact, it is the high-pressure steam released by it under decompression, which gives me enlightenment, since the power of steam can even explode an iron pressure cooker, so if the power of steam is released, can it become a force ......"

The explosion of the pressure cooker mentioned by Sun Zhongyue is the biggest shortcoming of the pressure cooker, although Zhu Mingzhong designed the safety valve, when the pressure in the pressure cooker is too large, the safety valve will be opened, so that the pressure in the pot will not exceed a certain threshold, and the pot will not explode. However, due to some man-made reasons, the pressure cooker still had many explosion accidents.

Hearing that he was inspired by the explosion, Zhu Mingzhong couldn't help but smile bitterly in his heart, he didn't expect that the explosion would have such an effect.

"So it's designed to release steam that could have caused an explosion into the piston, and the steam pushes the piston upward. When the piston rises to the top, the residual steam is finally released, and the steam is controlled by the slide valve to enter the piston alternately...... Well, I personally prefer to call it a cylinder. ”

When Sun Zhongyue explained his design, the pressure cooker over there had already been pressurized, so he said to everyone.

"Words are unfounded, now you can see how it works."

I saw Sun Zhongyue walk to the side of the pumping machine, and the moment he pulled a wrench with his hand, a roar of machinery immediately sounded in the room!

Accompanied by the roar of the machinery, Zhu Mingzhong could see the residual steam spewed out from the cylinder of the pumping machine, and in the bursts of "pop......" sound, a large amount of residual steam was released, although it could be seen from this how much it was caused, but Zhu Mingzhong was still shocked by the roar of the machinery in his ears.

In the operation of the steam pump, the people present were all introduced into a novel world, although people were surprised that this machine was the machine, but they could not realize what this roaring mechanical sound meant to the Ming Dynasty and the world.

But Zhu Mingzhong, as a person who has come over, knows very well what the invention of the steam engine means to the world, it is enough to use all the beautiful words in the world to praise it and praise it, because its appearance will change everything!
