Chapter 2478: The Treasure Island Must Be Seen in Person

"We're back." Li Yi saw three spots of light appear on the water and gradually approach the yacht.

After about five minutes, the people on the boat first fixed the fishing net handed by the little robot, fished out the little robot, and then pulled the net.

"Quick, give us a bath, seawater is corrosive."

Ling San San shouted and ran to the place with the water pipe, where people were already standing, turning on the faucet to wash the little robots.

The four people dragged the fishing net to the yacht and took out six pieces of things of different colors, some gray, some brown, and some white.

On the scale, Li Yi stood by and watched. The largest piece was 91 jin, 2 liang and 1 qian, and the smallest piece was more than 55 jin and 0.1 qian.

The six pieces added up to 410 jin, 5 liang and 3 qian, which was converted into grams to 262,612 grams.

When it was handed over to Li Yi, the weight was 525 jin, 2 liang, 2 qian and 4 fen, which was a big harvest.

"This piece will take a hundred years!" Li Yi sighed as he looked at the largest piece of white ambergris...

He looked at the night sky, and it was probably drifted from the island next to him.

"Turn, go to Socotra Island." Li Yi wanted to see if there were any more.

According to records, ambergris was discovered because Arab fishermen on Socotra Island found something in the stomach of a whale after killing it.

Socotra Island belongs to Yemen, but no one kills whales now.

This proves that there are many whales here, otherwise where would the people on the island kill them? Go to Antarctica? With their navigation skills?

"These ambergris are worth a lot of money!" Princess Yongmu had seen ambergris before. Others sent it to the palace, and the palace generally used it to make incense and burn it.

At that time, Li Yi did not write medical books, and ambergris was only used as a spice, and a lot of it was burned.

Now I understand that ambergris is the vomit and excrement of whales. It soaks in sea water and changes color over time. White is the best.

It can be made into burning incense and can also be used as medicine. It is better than musk and civet. When making perfume, it becomes a fixative to make the fragrance last.

"The white-robed Arabs here have some, and they also burn them to make smoke, which is a waste. Their incense-making technology is too poor.

When we return, we will go to the Tianhai area and walk close to the shore. I guess we can still encounter a lot of them.

To be honest, this thing is not very convenient to use in medicine. Musk and civet can both replace it.

Forget about artificial synthesis for now. We don't have the technology. Even if we synthesize it, the cost is still high."

Li Yi introduced the situation and decided to go to the Indian Ocean and stay close to the shore.

According to the records, there are many ambergris in Arabia. If you go west for a day and a night, you can reach the place where ambergris appears in the Sumatra Kingdom.

This proves that there are indeed many whales in this sea area. There are probably more in the sea water. They gradually approach the shore with the waves.

There is a southwest monsoon, which blows twice a year. Every time, things floating in the sea will move closer to the shore.

In addition, when there is a storm under a typhoon, some ambergris will be blown to the shore.

"It's a pity that it's not all white. Other colors are not as good as white."

Princess Yongmu looked at the ambergris of other colors and felt regretful.

"The formation of ambergris is a natural saponification reaction. Even if the color is not good enough, I can extract useful things from it by artificial saponification.

In such a large piece, the useful thing is called ambergris alcohol, which generally accounts for a quarter of the total weight.

Other things are useless, but for making incense, you cannot use ambergris alcohol extracted alone, which is too extravagant."

Li Yi looked at the ambergris with a not-so-good color without any regrets. Naturally, the quality is poor, and it can be affected and changed artificially.

"It's in chemistry, right? I haven't learned it yet." Princess Yongmu knew which subject it belonged to.

Lijia Zhuangzi taught physics, chemistry, astronomy, geography, botany, zoology, medicine...

Ministers mainly studied management and economics, finance branches, etc.

Music, painting, poetry, and foreign languages ​​did not need Li Yi to teach. He occasionally taught some Western painting techniques, including anatomy of human body painting.

"Learn slowly. The craftsmen and their children in our village are enough to train a large number of good teachers, plus students.

But I dare not teach too much, for fear that someone will learn and spread it overseas. People overseas should not be exposed to these knowledge so quickly."

Li Yi supports the spread of Tang culture and is conservative about professional knowledge.

Teach others, they use it to make weapons and turn around to fight against Tang.

Chemistry and physics are amazing, especially what is taught in Zhuangzi, which is more than a thousand years ahead of the current world.

Start directly, including providing experimental equipment, materials, and theoretical support.

Teach other children in Tang, at most teach them junior high school physics, chemistry and mathematics.

Those with good academic performance can come to Lijiazhuangzi for further study. One will stay for further study, and don't expect to go abroad.

People from outside are not taught, and junior high school students are not taught. Tell the students to press their fingerprints and sign a contract. If they leak it to the barbarians, it will be a serious crime.

Li Yi knows that if you understand junior high school mathematics, physics, and chemistry, you can understand some technology written in the newspaper.

It’s okay to be a bookkeeper, but you’re not a professional accountant. Even if you want to be an accountant, it’s easy to learn after you’ve learned math well in junior high school.

The purpose of his nine-year compulsory education at that time was this. There is a lot of knowledge that is needed in life, and what he learned in the nine-year compulsory education is enough.

The key is that after completing nine years of study, people have the ability to continue learning.

Other countries are still early. When most people in the Tang Dynasty know it, there is no need to control it, and they can't control it.

People from other countries will chase after you, and you will be exhausted.

"Hehehe!" Li Yi thought and couldn't help laughing: "When you catch up a few steps, you will be people from the Tang Dynasty."

"Who are people from the Tang Dynasty? The white-clothed Arabs here? They believe in religion." Princess Yongmu said curiously.

"You can be a Tang Dynasty person no matter what religion you believe in, but you must recognize Chinese civilization as the mainstream. I will find a way later."

Li Yi thought of his own country. Due to historical reasons, he couldn't get rid of all religions.

Through economic development, other people can support the regime. Can you not eat if you believe in something?

Fifty-six ethnic groups have become so stable in a few decades. The whole world is jealous and wants to make his country civil strife.

Look at Myanmar, Thailand, India, and Bangladesh. The ethnic, racial, and caste issues are so serious! There are always conflicts.

"Yeah!" Princess Yongmu thought of the foreigners as the current Tiele Ten Clans, Khitan, and Xi. Don't they all want to be Tang people?

They always rebelled before, but they won't in the future because they don't have automatic rifles.

"Eat and rest. We will arrive at the island tomorrow morning. There are people living there. Some of them should believe in one religion, and then they believe in another religion.

Let's stay there for a few days. I will treat them and tell them that those religions are wrong. Believe in my Tang Dynasty."

Li Yi kept looking up information. It was impossible for him to learn these things at ordinary times. It was useless.

He found out that in history, the people on this island believed in God, and later they all believed in Allah.
