At this time, there was no defensive force in Fort Relanje. As soon as Li Zhi's army arrived, the gate of Fort Relanje was opened. The remaining more than 100 Dutch artillerymen, women and children in the fort knelt on the ground, begging Li Zhi to let them go.
A way out.
Li Zhi waved his hand and said: "These red hairs are all habitual pirates. They have robbed many places and killed many Han people. Women and children were left behind, and the soldiers shot them all."
Two hundred soldiers from the Trapping Regiment rushed forward, tied up the artilleryman, and took him outside the fort to be shot. The remaining soldiers searched the fort to see what the Dutch had left behind.
Finally, Li Zhi found 110,000 taels of silver in the fort. The silver was probably earned from Japanese trade and was all Japanese-style silver. Li Zhi waved his hand to the three thousand soldiers and two thousand fleets participating in the battle.
Each of the artillerymen was given five taels of silver, which made the soldiers raise their arms and shout with joy.
Only one soldier was injured in this battle, and there were no other casualties at all. I was really happy to get the bonus.
After capturing Fort Relanje, Li Zhi was not prepared to occupy it. Occupying such a fortress would require at least several hundred people to defend it, which was a heavy expense. Li Zhi had a stronghold in Hsinchu, and there was Hsinchu whether he was going south or north.
As a transfer station, there is no need to add a foothold like Relanze.
There were some residents in the town next to Chikan Fort. After liquidation, it was found that there were 2,400 Han Chinese who had been reduced to red-haired slaves, 300 Chinese traders and 1,100 Southeast Asians.
Of course, the Han slaves were immediately freed. Those who were willing to go to Hsinchu could go to Hsinchu with Li Zhi. Those who were unwilling to go to Hsinchu should go to Hsinchu first and wait, and then take a boat back to Fujian. But it is expected that after seeing the wealth of Hsinchu, most of these people
Most will stay in Hsinchu.
Chinese traders are treated the same way.
One thousand one hundred Southeast Asians stayed in Relanjia and were responsible for demolishing the Forts of Relanjia and Chikan. Although Li Zhi was not prepared to occupy this stronghold, he did not want the Dutch to come back and occupy it again. The Southeast Asians were
Li Zhi temporarily worked as a hard laborer, doing the physical work of demolishing the city. After demolishing the castle, Li Zhi would load these Southeast Asians to Hirado. There was a Dutch business store in Hirado, and the Southeast Asians could return to the Dutch colony from there.
.
Li Zhi dealt with the Dutch in Fort Relande, and had nothing to do in Taiwan. He returned to Tianjin with the fleet.
Back in Tianjin, Li Zhi had nothing to do every day, so he wondered whether he could invent some new weapons to improve the combat effectiveness of the army.
To make a new weapon, the most critical thing is new gunpowder. If black powder is used, the current Mini rifle is basically the limit of black powder weapons. There is no black powder firearm in history that is stronger than the Mini rifle.
.Only with the development of new gunpowder and new firing powder can the power of guns and artillery be greatly improved.
However, although Li Zhi knew some chemical knowledge, there was no classification of minerals in this era. If Li Zhi wanted to produce new gunpowder, he would be faced with minerals with various Chinese names. Just understanding what compounds these minerals actually are would be difficult.
It will take Li Zhi a lifetime.
It is impossible for Li Zhi to develop a systematic chemistry by himself.
Li Zhi thought for a while and decided to go to the Taoist priest Cao Shoudao. Cao Shoudao was good at alchemy and knew a lot of chemical knowledge.
Cao Shoudao still lived in a small courtyard in the west of the city. When Li Zhi knocked on the door, a boy of thirteen or fourteen years old opened the door. The boy with his head in horns had grown up.
Li Zhi smiled and said: "Little Taoist, I'm looking for your master, Taoist Master Cao."
The young man agreed, ran in quickly, and shouted: "Master, Master! A high official is looking for you!"
After a while, Cao Shoudao, who was wearing a robe, came out. He had not seen him for several years, and he had a few wrinkles on his face, but he was still in good spirits. When he saw Li Zhi, he quickly knelt down and shouted: "Cao Shoudao
I’ve met Uncle Xing Guo!”
Li Zhi helped Cao Shoudao up and said with a smile: "Master Cao, I'm here to disturb your Qing Xiu again!"
“What I wish for!”
Li Zhi laughed loudly, walked into Cao Shoudao's yard, and said straight to the point: "Taoist Master, do you know about sulfuric acid and nitric acid?"
Cao Shoudao was stunned and asked, "What is that? I don't know!"
Li Zhi explained: "Perhaps Taoist Master Cao knows it, but it's just called by a different name. The so-called sulfuric acid is an oil-like thing, but it is corrosive. If it comes into contact with paper or raw meat, it will corrode the things to black with just one touch. The so-called sulfuric acid
Nitric acid is a kind of water made from saltpeter. If it comes into contact with wool and other objects, it can turn these fibers yellow."
Cao Shoudao pondered for a moment and said: "My uncle is talking about nitric acid, I don't know. But the sulfuric acid that my uncle is talking about is somewhat similar to the green vitriol oil that I refined. This thing is so overbearing that even when it comes to iron, it will
It can corrode and rob. This substance is somewhat viscous, just like oil."
Li Zhi's eyes lit up and he said, "What the Taoist said is probably dilute sulfuric acid. Can you show me some, Taoist?"
Cao Shoudao said: "This thing is overbearing and difficult to store. I make it fresh when I need it. Since uncle wants it, I will burn some and show it to him."
Li Zhi nodded and said, "That's great!"
Cao Shoudao nodded and went to tinker. He invited Li Zhi to the inner courtyard to watch him make green vitriol oil. He took out many bottles and jars: including a large crucible, a curved porcelain tube, and a
A straight porcelain tube, two large porcelain jars with side openings, and a small porcelain jar with a bottom full of mesh holes.
He dug out some raw materials from several jars, which was green vitriol.
There were many earthen stoves built in the courtyard of Cao Shoudao's house. At this time, Cao Shoudao chose a stove with an opening at the top. The air outlet was separated from the top opening. Cao Shoudao placed the crucible inside, put in alum material, and covered the pot.
Cover, seal the edges with clay, insert the curved porcelain tube into the top opening of the stove, put it on the tubular hole of the crucible lid, and seal it with clay.
Insert the other end of the bent porcelain tube into the large porcelain vat. The cover of the porcelain vat should be sealed with clay. Connect the side holes of the two porcelain vats with a straight porcelain tube. Finally, put the small porcelain vat on the porcelain vat and seal the space between the vats with clay.
After handling this large pile of things, Cao Shoudao finally started to light the crucible.
After burning for a while, when acid gas emerged from the sieve at the bottom of the small tank, Cao Shoudao poured well water into the small tank. After a while, bubbles appeared in the well water. Those bubbles were quite big at the bottom, but when they went up
During the movement, it became smaller and smaller, gradually disappeared, and apparently dissolved into the water.
As more gas dissolves in the well water, the well water becomes more and more viscous.
After burning for a while, Cao Shoudao looked at the heat, nodded and said, "It's almost done."
He extinguished the fire under the crucible, carefully lifted the water jar out, and said, "Uncle, this is green vitriol oil."
