The construction site of the railway is carried out in sections, and at the end of this mountain narrow-gauge railway is the construction site of the dam and the factory area. Pen & Fun & Pavilion www.biquge.info

The name of the plant is the Sulfur Acid Plant, which is actually produced in this plant for both sulfur and nitric acids. In fact, the production of nitric acid is also produced with sulfur acid, sulfur acid is known as the mother of modern chemical industry, without sulfur acid, there would be no powerful modern weapons, and there would be no dazzling variety of new weapons with great power.

The method of making nitric acid is very simple, after having sulfur acid, mixing sulfur acid with saltpeter, and then using a net made of platinum as a catalyst, you can get nitric acid. At this time, no one had discovered the value of white gold, which was mostly a companion in gold mines, a white metal obtained during gold panning.

Because of the lack of knowledge of the value of this kind of thing, the white gold produced in this era was regarded as a better silver to make jewelry.

The Spanish colonists had a lot of platinum on hand, and they didn't know the value, so they sold this kind of thing to the Ming Dynasty as high-grade silver, which was a little more expensive than silver. By the time they knew the value of white gold, it was after the eighteenth century. Because of this, Wang Xinyu bought a lot of platinum from the Spaniards before.

Because Wang Xinyu bought a large amount of platinum, the Spaniards sold it to Wang Xinyu at a price that was double the amount of silver. The price was so cheap that decades later, when Westerners discovered the value of white gold, the price of white gold surpassed that of gold! But now the price is only one-fifth of gold.

Platinum is more used for military purposes, and is a necessity for the industrial production of nitric acids.

On the site of the sulfur acid plant, workers adapted from the captives of the people are working. The foundation of the factory has been dug up, and the workers carry the stones to build on the foundation. The creek has been cut off, and a large number of workers are building a barrage. At the reactor construction site of the factory, the skilled workers led by Song Shihui are making the mold of the reactor tower, which is a very large iron mold, which is three zhang high and one zhang and two feet in diameter.

"After this oversized iron mold is ready, the lead can be melted and poured into the mold." Song Shihui said.

Lead has a low melting point and cools quickly after being poured into the iron mold, and when it cools, the iron mold is opened, and a lead-cast reactor is completed.

Sulfur acid plant actually has another purpose, which is to remove sulfur from pyrite. There is a lot of pyrite in China, but because of the high sulfur content of iron ore, the quality of steel produced is very poor. At that time, we didn't know how to remove sulfur, and the sulfur contained in pyrite was useless at that time, because gunpowder was sulfur in those days, and sulfur dioxide produced after ironmaking was useless waste. However, with the sulfur acid plant, the sulfur dioxide obtained from the extraction of pyrite can be used to produce sulfur acid, which can obtain powerful explosives.

Iron ore, stripped of sulphur, can be transported by train to gun factories to make steel and weapons.

After Wang Xinyu went to the construction site of the sulfur acid factory, he returned to Anping City, and after arranging things, he went to Song Yingxing's house, because Song Yingxing had a few days to live, and he wanted to personally send this great scientist to the end of his life.

Five days later, Song Yingxing died of illness.

In order to allow future generations to commemorate this great scientist, Song Yingxing's body was sent to Hangzhou and buried at the foot of Lychee Peak in Pingshan Mountain, West Lake. It was originally Zhang Huangyan's cemetery in real history, because of Wang Xinyu's crossing, Zhang Huangyan lived well, so this feng shui treasure was given to Song Yingxing.

On the cemetery, a memorial hall of Song Yingxing was also established; In the Dongfan Gun Factory, a Song Yingxing Memorial Hall was also built. In the future, Fengxin, Jiangxi, Song Yingxing's hometown will be recovered, and a memorial hall will also be established in his hometown; In the future, the Hanyang Industrial Park will be established, and a Song Yingxing Memorial Hall will also be built at the Hanyang Gun Factory. A number of memorials will allow future generations to remember this scientist who made great contributions to the industrialization of the Ming Dynasty.

……

Thousands of miles away, Singapore Marina.

A huge battleship slowly sailed into the port of Singapore, and the sailors on board were dressed in crisp white sailors' uniforms, blue streamers and shawls fluttering in the wind, making each sailor look refreshed and invigorating.

After owning the battleship, the Nanyang Navy officially carried out a comprehensive redress, and the navy's military uniform achieved a unified military uniform, the summer dress and dress are all white, and the winter is dark blue, and the clothes have copper buttons on them, making this military uniform look more majestic.

The river division has not changed its outfit yet, after all, it needs hand-to-hand combat, or armor protection. But the navy is different, as the power of weapons increases, the navy no longer needs to engage in broadside battles, and armor is meaningless, but hindered.

Yu Chenglong stood on the dock, looking at the returning battleship, on the one hand, he was shocked that the Ming Dynasty had such a powerful navy, and on the other hand, he felt sad that the Qing court would be finished sooner or later.

I have to say that Nanyang is a good place, and during Jackie Chan's time in Nanyang, he understood a truth: it turned out that the Qing court only knew how to focus on the Central Plains and Jiangnan, which was really a short-sighted place, and Nanyang was such a rich place, but the imperial court cut off contact with the outside world because of the sea ban.

"Nanyang is really rich! There are so many gold mines, copper mines, countless rice grains, hundreds of ivory, countless jewels, and many spices! The island of Java is a spice producing area, and there are many spices that are valuable in the country, but there are many here! It's so rich! No wonder Ming Ting relied on sea trade to turn over! Yu Chenglong sighed.

"My lord, let's go, it's time for us to go, let's go to Myanmar first! After going to Myanmar, I have to go to Kunlun Prefecture. Yu Peng reminded on the side.

The ship Yu Chenglong took to Myanmar was a cargo ship, but in fact, this ship was Liu Qi's slave trading ship. Of course, it was impossible for a slave ship to sail to Kunlun Prefecture empty, and in the past, the ship was full of goods, including clay pots, cloth, iron pots, woodcutters, broadswords, iron spearheads, iron arrowheads, hunting bows, muskets, gunpowder, grain, and other goods.

Except for a part of the grain and cloth that was used by Liu Tao and the Ming soldiers who established the colony, all the other goods were sold to the local blacks.

However, this is the first time in the history of Africa that a slave trading base has been established in East Africa. Previously, both Arabs and white Westerners traded slaves in cooperation with the Mali Empire in West Africa.

The Mali Empire, an empire founded by mixed-race blacks, the slave trade accounted for a large part of the empire's economy, and those mixed-race black soldiers, almost everyone was a slave trader, who used to carry weapons given by the Arabs and went into the grasslands and forests of black Africa to capture blacks; Now they are taking the weapons provided by the Western colonizers and going into the grasslands and forests of black Africa to capture blacks, and many more blacks have died at their hands than at the hands of whites.
