As soon as Jang Doo arrived on Jeju Island, he was pulled to his residence by Zhou Liyu, and Jang Doo saw a microscope in a messy room.

That's right! is what I call the microscope, although it is the simplest monocular, it can be regarded as a great progress in the history of medicine in the Ming Dynasty.

Zhou Liyu proudly introduced the use of the microscope and personally put a leaf under the microscope to observe.

Zhang Dou had to admire the perseverance of the ancients, and he was able to build a microscope with just a few words, which undoubtedly showed the strength of the wisdom of the Chinese nation.

"Mr. Zhou has worked hard! It's great to be able to build a microscope in such a short period of time! Zhang Dou said with his fists clenched.

Zhou Liyu waved his hand and said: "I'm ashamed! Buddhists say that there are 3,000 living beings in a drop of water, but Zhou has never believed it. But having a microscope opened Zhou's eyes, it turned out that there were so many creatures in places that could not be seen by the eyes! ”

"Sir, humble yourself, your medical skills have been superb, and you can be called a miracle doctor in the world!"

"Nope! The more he understood, the more Zhou realized that his original knowledge was nothing at all! That's right! Dashuai, the stinky artemisia juice you want has been made. This humble thing is really a treasure, and it works wonders for malaria. It turns out that there is a record of medical skills in the Eastern Jin Dynasty, but it was regarded as Artemisia by quacks such as us, which is really ashamed to say! Zhou Liyu said, handing a porcelain vase to Zhang Dou.

"This thing grows from north to south, and it only needs to be crushed to extract its juice immediately. If you soak it in spirits, it will work even better! Zhou Liyu continued.

Zhang Dou took the porcelain vase and was overjoyed, and the development of Taiyuan Island was in front of him. Malaria is the biggest obstacle in front of the Changxing army, and this infectious disease caused by mosquito bites cannot be prevented at all.

In the event of malaria in the army, the whole army will be defeated. There is no talk of occupying Taiyuan Island, let alone immigration.

Taiyuan Island is an important part of Zhang Dou's plan, and it is the guarantee for Zhang Dou's southward journey. The whole of China is short of copper, and the Philippines has world-class copper and gold mines.

There is Zhang Dou's confinement, and anyone who wants to do it has to ask him first. Although the dry silk people occupy Manila, it doesn't matter. The sea has its own laws, and a big fist has the right to speak.

If you go south to Taiyuan Island, you will first encounter the Gan Wax people in Keelung and Tamsui in Taipei, and Tainan is also occupied by Dutch people.

If you want to occupy the immigrants on Taiyuan Island, you have to face them. Now Changxingjun's fists are big enough to have the strength to wrestle with them.

After returning from Zhou Liyu, Zhang Dou went to the shipyard. The five newest Orca-class warships there are almost complete, and in a few days they will be able to complete their sea trials and then make an expedition to Taiyuan Island.

As soon as he entered the shipyard, Zhang Dou saw five tall killer whale warships in the dock. With a displacement of 600 tons, it was already the largest warship of the Changxing Army, and each battleship was equipped with fifty-two guns.

Among them, there were eight early sun cannons in close combat, and the rest were all 16-pounder, 18-pounder, and 24-pounder naval guns.

The thickness of the ship's plank has reached one and a half feet, and the plank after half a meter gives the killer whale warship a stronger protection ability.

They fully met the standards of a third-class sail battleship, and in some ways went beyond. Zhang Dou believed that once these world-leading warships appeared on the battlefield, they would be able to influence the situation on the battlefield.

His arrival flattered Steward Zhao of the shipyard, and hurriedly ran to greet Zhang Dou. took Zhang Dou to inspect the shipyard and explain the current situation of the shipyard to Zhang Dou.

Zhang Dou looked at it for a while and asked, "If you want to build a bigger warship this year, you can just raise any difficulties!" ”

Steward Zhao hesitated for a moment before he said, "Handsome! We could have built bigger ships, but ......"

Hearing this, Zhang Dou was not angry, and the development of his Immortal Island was only a few years. He should be content to have such a large navy, but Zhang Dou knew.

The vigorous voyage in Europe has been open for many years, and I must seize the opportunity of the last rise of China to surpass the West in an all-round way.

"Tell me about it! What's so difficult? Zhang Dou asked.

Steward Zhao organized the language and said, "Handsome! First of all, our wood is made of pine wood outside the gate, which is too easy to deform. And it's not hard enough to be an ideal wood for shipbuilding.

It is better to have fir and cypress, which we are lacking here. Even if you build a big ship, it will often leak and go back to the dock to repair it.

In addition, the speed and hull size of the current killer whale battleship are just right, and if a larger ship is built, the speed of the battleship will be reduced, which is really powerless for subordinates! ”

Zhang Dou hesitated and said, "The matter of wood will be solved this year, and wood will be shipped soon." It is possible that some of you will be sent to the south to build ships, so you have to be mentally prepared.

As for the problem that the sea ship is too large and affects the speed, first build a sample ship and go out into the water to see. It's bigger than the killer whale battleship, let's build a 750-ton one first! ”

"Yes! Handsome! Steward Zhao replied respectfully.

Zhang Dou left the shipyard and went to the craftsman's workshop, and the craftsmen who came back from Nagasaki have been completely integrated into the Changxing army.

Not only is the food here better than that of the Wa country, but even the work is not as tiring as the Wa country. No one has also equipped them with maidens to serve them, and now no one will leave even if they are driven away.

After the performance system was established, the enthusiasm of the craftsmen was particularly high. There are many craftsmen who are reluctant to go home late, and only by working more to get the silver in vain will they feel at ease.

Zhang Dou focused on inspecting the production workshops of cannon casting and immortal guns, and also rewarded craftsmen who increased the production speed of bayonets with a thousand taels of silver on the spot.

The white silver sparkled the eyes of the craftsmen, and everyone was full of energy to do something.

At the insistence of Zhang Dou, another batch of medals was created. Only those who have participated in the bloody battle of the Hunhe River are qualified to wear the gold medal, and those who can wear this medal are all veterans of Changsheng Island.

The silver medals are divided into the Battle of Changsheng Island, the Battle of Guangning Fort, the Extermination of the White Lotus Sect, the Surprise Attack on Yucheng and the Battle of Fuzhou, all of which are awarded to those who have made outstanding achievements in these battles.

There is also an iron medal that is awarded to those who have participated in combat, and a bronze medal that is uniformly awarded to those who have been wounded in battle.

The medal is not only an honor, but also a special right. Wearing any medal, you can not salute the official and wait for the other party to salute before returning fire.

Depending on the quality of the medal, you can also enjoy certain privileges. For example, when a mistake is made in a silver medal, the first-degree culpability can be reduced and so on......

In short, the medal is the direct embodiment of the military merits of the Changxing Army and the most intuitive manifestation of the value of soldiers.
