Matches, a daily necessities that are far away from people in the 21st century.

It actually has a full name - safety matches.

Like everything else you know, safety matches have come a long way.

Matches in the modern sense originated in 1669 when an alchemist accidentally created the element phosphorus.

About a century and a half later, it was studied in a laboratory by British chemists.

Three years later, French chemists redeveloped a combustible mixture based on yellow phosphorus.

It prolongs the life of matches, but it also carries great harm - phosphorus toxicity and osteonecrosis of the jaw.

It wasn't until 1845 that Austrian chemists developed non-toxic matches with red phosphorus that this changed.

However, there is still a long way to go before a real safety match is made.

Ten years later, the Swedes improved the method and invented the safety match.

He glued a mixture of potassium chlorate and sulfur to the matchsticks, while applying red phosphorus to the sides of the matchbox.

When using, the match head is gently rubbed on the red phosphorus layer to light the fire.

This is exactly the method adopted by Yang Chengying.

Red phosphorus and other products are industrial products, and the amount is full.

Red phosphorus, for example, is extracted from phosphorus minerals.

You can't get out without an industrial base.

The fundamental way to promote the further development of industry is to be driven by interests.

Therefore, Yang Cheng should show matches to the public, which also has the meaning of promotion.

After all, among the people who accompanied the sea this time, there were a large number of businessmen who originally stayed in Jiangnan.

Sure enough, Wu Kongxiu's eyes lit up when he saw the match. Look at the book

He clenched his fists and asked respectfully, "Your Highness, is there still such a match?" I want to buy some and take it with me."

As soon as these words came out, the voice of echo suddenly rose.

He spoke for everyone's heart.

"Of course you can, this thing was invented to be sold."

Yang Chengying smiled and said, "It's not just you, if other crew members also want to buy some, it's okay to go overseas to earn personal gains."

As soon as Yang Chengying nodded in agreement, the scene suddenly became lively, and they all said that they wanted to buy a batch of matches to go to sea.

In the past, people used flints, fire folds, or bow drills to make fire.

If you are at home, you will cover some of the burning firewood with ash before going to bed and turn it into charcoal, which will be used as a starting point for the next day.

If you have matches, things are much simpler, you can make a fire with a light wipe, and it is much more convenient to use than the previous various ways to make fire.

When they saw that Yang Chengying was silent, they immediately realized their gaffe, hurriedly stopped their mouths, and lowered their heads.

"Before you leave, go to Zu Zepei and buy some, and I'll give you some."

Yang Chengying said, "Remember that the first thing you need to do overseas is to protect yourself. If the other party asks you to scold me twice, you just scold and come back alive."

"Your Highness's teachings, the ministers should keep them in mind."

Everyone responded with neatly clenched fists.

"Well, that's all right, you'll have to work hard!"

Yang Chengying hugged his fists at everyone.

"I will live up to His Highness's expectations!"

The crew responded with neatly clenched fists.

For a variety of reasons, they choose to go to sea to fight for their lives.

But they have a faint feeling in their hearts that their trip will have an immeasurable impact on the future, and maybe they can leave a name in history.

It's exciting to be recorded in history.

"Let's rest early today and leave early tomorrow morning."

Yang Chengying nodded, waved his hand again, and everyone left the main hall one after another.

Princess Zhu Huixian walked out from behind, and she was about to enter Beijing with Yang Chengying.

She didn't like to be in the same room with so many people.

Raising his eyebrows at the princess, Yang Chengying asked proudly, "Princess, the matches I invented are easy to use, right?"

When she was in Shenyang, the princess once went to the kitchen and witnessed the whole process of lighting a match.

"It's easy to use, but the general shouldn't sell it easily, if he is learned, won't he lose money and make money?"

Zhu Huixian was a little distressed.

Although she is used to being pampered, since she followed Yang Chengying, she still knows that silver is not easy to come by after so many years.

"If you want to produce, it's not that easy."

Yang Chengying saw that there were no outsiders present, so he stretched out his hand and hugged the princess and walked to the inner hall, "The red phosphorus tablets on the cardboard box are extremely difficult to produce."

When they arrived at the inner hall, the two sat down face to face on the kang across the small table.

Yang Chengying continued: "Not only will I not hide my personal interests, but I will also generously invite businessmen to invest in the construction of match factories so that the people can afford to use matches.

More importantly, let Portugal and other Western countries also use it. They couldn't produce matches in a short period of time, so they had to buy them from me.

In this way, the match factory's business has improved, which in turn has led to the mining of phosphate rock and the renewal of equipment."

"Understood." Zhu Huixian nodded, "It turns out that the general wants Jiang Taigong to fish."

"That's exactly what it is." Yang Chengying smiled.

The maid brought the tea on a tray.

Zhu Huixian got up and picked up the tea cup in the tray and placed it on the small table next to Yang Chengying: "Since the matter of going to sea has been resolved, the general should put his mind on the matter of the face saint."

"Your Highness, don't worry, we are going to Jingshi, and we will definitely be able to come back with all the beards and tails."

Yang Chengying picked up the teacup and said confidently, "Your Majesty just wants to establish his authority as a king in the short term by seeing me, and at the same time eliminate the influence of the year."

"Hey! The things of the year were done too much, causing the generals of the towns to have lingering palpitations."

Zhu Huixian sighed and said, "The generals saw that there was no good end for those who were loyal to the monarch and served the country, so everyone naturally thought about self-preservation. It is said that You Shilu has changed into a different person, and he even connived at his subordinates to plunder the village."

"It's probably providential."

Yang Chengying couldn't help but sigh.

The things You Shilu did were all done by Zuo Liangyu in history.

Things have changed, Zuo Liangyu was under Yang Chengying, staying in Liaoxi to train the army diligently, and did not get involved in those messy things.

The honest man You Shilu met by fate, but he participated. In the end, he was dyed out of another appearance by the big dye vat, and I don't know how Inspector Yuan should feel if he knows it underground.

Early the next morning, the fleet set off from the old wharf of Port Arthur and set off on its first voyage.

Yang Chengying and the princess were at the pier to see them off.

"May they all come back safely, and bring back the tree of tears that the general wants."

Zhu Huixian stood on the dock, looking at the fleet sailing in the distance, and said in a low voice.

"It will."

Yang Chengying is also full of expectations.

According to the time calculation, this year is the first tearful tree (rubber tree) and the first natural rubber sent by Spain.

Thanks to the world's cold climate, natural rubber can be stored for a short period of time.

Rubber trees will be planted on Jonlong Island, and will be planted in the South Seas when a base is opened up in the future.

With it, it is immeasurable for the development of industry.

"Let's go, we should also take the train to Liaoxi."

Yang Chengying watched the fleet disappear into the sea and turned his head to look at the princess.

The princess nodded.
