Daming: I, Yang Xian, really govern Yang!

That's right, what Yang Xian wants to do is canned food.

That day at the Wei Guogong Mansion, Xu Da's words reminded him of this incident.

You must know that canned food is an artifact to maintain the health and morale of the crew during long voyages.

Right now we are just crossing the East China Sea to fight against Japan.

Because the voyage time is short, many fatal problems have not yet appeared. You must know that seafarers will suffer from scurvy if they cannot eat fresh vegetables and fruits and lack vitamin C for a long time at sea.

Since the Age of Discovery, scurvy has been an inescapable nightmare for sailors for hundreds of years, and it is also the most feared existence by Western sailors.

In 1521, Magellan led more than 200 crew members to sail around the world. In the end, only 18 people completed the feat, and a considerable number of the crew members died of scurvy; in 1740, six battleships led by British Admiral George Anson , more than 6 sailors sailed around the world goldenly. Four years later, when the fleet returned to port, people found that only one flagship ship docked, leaving hundreds of sailors very weak. It turned out that more than 2000 sailors were killed by scurvy during the voyage. .

It is precisely because of this that experienced captains will not bring full supplies when they sail, because during the voyage, at least half of the crew will die due to sepsis or other injuries. If they bring too much, Provisions are a waste.

It was not until the end of the eighteenth century that the French invented the can, which greatly improved the survival rate of sailors.

At this time, some people will ask why scurvy did not appear during the Yongle period of Zheng He in the original time and space.

One of the important reasons is bean sprouts.

Zheng He's fleet carried the necessary beans, millet, millet, millet and other seeds. These seeds will germinate when exposed to water, forming bean sprouts rich in vitamin C.

It can well ensure the necessary intake of vitamin C for crew members.

But in Yang Xian's view, how could it be possible to rely solely on bean sprouts to achieve the great Ming Dynasty?

We must get the canned food out in advance.

For canned food, the best material is tinplate, whose scientific name is tin-plated steel plate.

As the name suggests, it refers to a cold-rolled steel plate plated with a thin layer of metallic tin on the surface.

Tinplate has a certain strength and hardness, good formability and is easy to weld. The tin layer is non-toxic and tasteless, and the surface is bright. Tin mainly plays a role in preventing corrosion and rust. The common cans and beverage cans we see in later generations are all made of tin-plated sheets.

With today's Ming Dynasty's technology tree, it is obviously not realistic to produce tinplate cans.

Fortunately, Yang Xian came up with a substitute for canned containers in advance. That’s right, it’s glassware!

The earliest cans in the original time and space were made of glass bottles, cork and iron wire, and the mouth of the bottle was tightly plugged.

Even in the 21st century, canned fruits are still customarily made in glass bottles.

If canning is to be made on a large scale, glass containers must be used on a large scale.

When large-scale glass canned food appears on the market, it means that the current high glass price system will collapse, which will seriously affect the huge profits of the glassware manufactured by Mingji Glass Factory.

After all, when wealthy people know that they already have enough stain-free glassware that they cherish so much that they can use it to hold food, they will definitely not want to pay the IQ tax anymore.

Fortunately, over the years, enough money has been made from glass.

Yang Xian had no intention of making this money in the long term from the beginning. His original purpose was to suppress the price of glass products to the current price of porcelain, so that ordinary people could eventually afford it.

To him, merit points are worth much more than money.

Of course, the price of glass products has not completely collapsed yet, and it will not happen so quickly. It will have to wait until canned food becomes completely popular on the market, and now Yang Xian is just making a batch of canned food for Xu Da's next overseas trip.

According to the design drawing given by Yang Xian, the glass factory quickly fired the glass cans and bottles.

Now it’s finally time to start canning.

For canned food, there are two key features in production, sealing and sterilization.

Taking these glass cans and bottles, Yang Xian began to make them.

First, rinse the glass bottle with running water, both inside and outside. Then put the bottle into the pot and add water until it boils.

The entire boiling process lasts for 30 minutes, and is finally taken out and set aside.

Then use strong alcohol, pour it into the bottle, and sterilize it again.

Especially at the mouth of the bottle, Yang Xian dipped a cotton swab in spirits and wiped it clean carefully, and finally dried it in the shade.

At this point, the processing of cans and bottles has been completely completed.

Then comes the choice of food.

This time, Yang Xian chose the ripe fruit of the season, yellow peach.

Peel and core the good yellow peaches you bought, cut them into pieces, and then soak them in the sugar water that has been boiled for a period of time. Then you can put the yellow peaches and sugar water together into a glass can, and then put them on the wooden can. Tighten it, there is no need to tighten it completely at this time.

Finally, put them into a large pot and steam them for about twenty minutes to complete the entire process of canning yellow peaches.

After taking it out of the pot, quickly plug the cork tightly while it is still hot.

Because of the principle of thermal expansion and contraction, the air pressure inside the can is smaller than the outside world, which will form a complete sealing effect.

After sealing, turn the glass jar upside down so that a vacuum will form inside, further extending storage time.

For a person from the 21st century, the production of canned food can be easily completed even without a system.

The whole experimental process was perfect.

Although Yang Xian was only holding a small can of yellow peaches in his hand, it represented endless wealth and merit points.

Canned food is not limited to sailing personnel.

The military can use it.

Even ordinary people can use it.

Take the current Jiangnan area as an example. Due to geographical reasons, it is completely unsuitable for raising cattle and sheep. Therefore, except for wealthy families, ordinary wealthy people cannot afford fresh beef and mutton. They can only eat cured meat, bacon, chicken and duck. Fish pig substitution. After all, pork is a cheap meat. Because the people in Jiangnan are wealthy, the demand for beef and mutton is actually huge. If canned beef is made by then, it will definitely be popular!

Not to mention canned fruits, in the long autumn and winter, it is simply a huge profit, right?

The effect is the same as Yang Xian's previous off-season greenhouse vegetables, and the difference is that the output of canned food is much larger than that of greenhouse vegetables.

At almost the same time, Xu Da, who was in the capital, finally received the imperial edict for another expedition to Japan.

The goal this time is very clear, to completely occupy the Iwami Mountain Silver Mine in Izumo Country, and then establish the largest silver mine there in the Ming Dynasty, and steadily transport silver for the Ming Dynasty in the future.

Xu Da's job was only to conquer. After the occupation, there were officials and generals staying behind.

From now on, Izumo Country will be Ming Dynasty's first overseas military stronghold.

Before setting off for the expedition, Yang Xian came to the capital as promised with 500 boxes of canned yellow peaches.

"This is this?" Xu Da looked at the wooden boxes in front of him with a puzzled look on his face.

Yang Xian smiled and said: "As promised last time, the gifts prepared for Brother Xu before the expedition finally caught up."

Xu Da rode the Ming Dynasty's newest warship, the Yangzhou, and led the Ming Dynasty's mighty navy to attack Japan again!

Flags flying on the deck of the Yangzhou warship.

Xu Da was sitting on a handsome chair, holding a glass can in one hand and picking up a piece of yellow peach inside with chopsticks in the other hand, and put it into his mouth.

It is sweet in the mouth. Although the sweetness is a bit greasy, it tastes very enjoyable.    Exceptionally delicious!

You can also eat fruits on the sea, what else can you say!

I didn't expect that this kid actually did it. Is there anything in this world that he can't do?

Xu Dasan swallowed another piece of yellow peach into his belly, licked his lips, and thought to himself.

When he saw the five hundred wooden boxes, Xu Da thought they were something. When he opened them, he realized that they were yellow peaches that had been treated with Yang Xian's special techniques.

According to Yang Xian, these canned yellow peaches will not go bad if left for a year.

The only shortcoming is that the quantity is still a little small.

Although the five hundred large boxes of canned yellow peaches are a lot, you must know that the Ming Dynasty navy they sent troops this time has tens of thousands of people.

Xu Da was not very reluctant to eat on weekdays. Every once in a while, he would let his soldiers share some.

at this time.

The guards suddenly came to report that they had discovered traces of Japanese warships.

Xu Da stood up, took the telescope and took a look, his face immediately showed a solemn expression.

"Just in time!"

In Japan, because of the previous invasion by the Ming Dynasty army, the daimyo of the coastal kingdoms were particularly nervous.

In order to deal with this national crisis, the North and South Korea actually reached a ceasefire agreement and worked together.

After all, the two battles in front of Izumo Kingdom were so terrifying that they completely subverted their understanding of war.

In the past, no one could have imagined this day.

Sure enough, external pressure and threats are important factors in promoting internal unity and cooperation.

After high-level discussions between the North and South Korea, the slogan they put forward was to deny the enemy on the other side, attack the enemy on the sea, destroy the enemy on the waterfront, and annihilate the enemy on the beach.

In their opinion, it is most beneficial to them to set the battlefield on the sea.

Didn't their ancestors do this before more than a hundred years ago, "defeating" the then invincible Yuan Dynasty army.

Since their ancestors were able to do it more than a hundred years ago, they should reasonably think that they can do the same.

Therefore, at several ports where the Ming army landed and docked, Japan had already set up heavy troops. At this time, the Ming Navy was seen from a distance.

The Japanese warships came out, vowing to defeat the Ming Navy.

With the efforts of the whole country, Japan actually assembled thousands of warships, although a large part of the so-called warships were modified from fishermen's fishing boats.

But even so, when thousands of warships lined up on the sea, they were very majestic.

In terms of the number of warships alone, Japan has more.

On the sea, the warships of both camps were getting closer and closer.

The atmosphere was extremely tense for a while.

At this time, Japan's firearms had not yet developed, and they also understood their disadvantages. Therefore, after approaching a certain distance, the Japanese fleet formation began to slowly spread out.

Xu Da saw all this in his eyes, and he did not panic, because if the opponent wanted to attack, he must still get closer.

He ordered all warships and artillerymen to be ready.

After the opponent entered the range of his side, with an order, the Daming Navy launched the attack first.

The Ming warship at the front fired a salvo of artillery!

Boom boom boom!

With the sound of intensive artillery, the first large-scale naval battle between Ming Dynasty and Japan officially began.

There was a dense sound of artillery fire.

The shells, carried by the sea breeze, roared past the sea level and flew towards the Japanese warships.

Suddenly, I saw flames all around the Japanese warship, sea water splashing, rough waves, and a burst of smoke.

The smell of gunpowder smoke and blood began to linger on the sea.

Because the Ming Dynasty was fighting in the ocean, both the number of warships and the number of naval forces were smaller than those of the Japanese side.

But in terms of warship quality and weapons, it is a crushing leader.

When the Japanese side knew that the Ming army had firearms, it was naturally impossible for Japan to make no preparations at all.

Under the command of the other party's commanding general.

Soon there were hundreds of small warships, igniting the fuel of hay on board, and then launched a suicidal charge towards the Ming fleet.

"This Shenhuo special agent team is specially prepared for you!" Naoyoshi Ashikaga stood on the warship, looking at the burning warships on his side, charging towards the Ming army without fear of death, and said coldly.

Ashikaga Naoyoshi raised his head and glanced at the sky, his eyes determined, as if he was sure of victory.

"Even God is on our side, kamikaze help me!"

Today's wind direction is exactly northwest!

In Ashikaga Naoyoshi's view, as long as the warships of these Shenhuo Special Forces can successfully collide with the warships of the Ming Navy on the opposite side, the fire will definitely be directed to the other side's warships.

Seeing this situation, Xu Da ordered all warships to increase their artillery fire.

But with the firearm technology of this era, no matter how intensive the firepower is, there will always be fish that slip through the net.

There were still some warships that broke through the encirclement and rushed towards the Ming fleet.

The target of some of the warships of the Shenhuo Special Forces is the Yangzhou. It is obvious that the principle of catching the thief first is captured by the king. Japanese people who have studied Chinese culture since childhood also understand.

Seeing this situation, Xu Da sneered: "You must think this is Red Cliff? Do you really think this is still the Three Kingdoms era more than a thousand years ago? I will let you know today how ridiculous you Japanese pirates who sit in the well and watch the sky are."

Under Xu Da's order, the large warship Yangzhou he was riding on did not retreat but advanced. He directly started the steam engine and rushed towards the burning small fishing boats of the opponent.

At the same time, five burning small fishing boats that broke through the siege collided with the Yangzhou.

For a moment, thick smoke billowed out, obscuring the figure of the Yangzhou.

In the distance, Ashikaga Naoyoshi saw this scene and raised the corners of his mouth slightly, showing a smile of victory. He could see clearly that the Yangzhou was the main ship of the Daming Navy.

As long as this warship is sunk, the formation of the Ming Navy fleet will be in chaos! (End of chapter)
