Everyone visually inspected the red coral about a foot high, and the red coral branches were very thick.

The branches of red coral resemble antlers, which is an almost perfect red coral.

To Xiahou Xun is very valuable, to others, red coral does not have much practical value.

Most people don't have the idea of red coral, and they're not interested in the strange stones.

Later, some of the guards brought over the strange stones from his collection.

Liu Zhang saw that some strange stones were inlaid with paleontological fossils, but Xiahou Xun didn't know that these were fossils.

He felt the traces inlaid in these stones, which looked like ancient animals.

"These stones are inlaid with fossils, which are tens of millions of years old, to say the least."

Liu Zhengchen pointed to the trilobite fossil, which had traces of several trilobites.

Liu Zhang told them about paleontological fossils, which made Liu Chengcheng and them learn a lot.

I've seen similar stones before, but I've just treated them as ordinary stones.

Since Liu Zhang said that there were ancient fossils in some stones, they felt that Liu Zhang was also interested in these ancient fossils.

Dinosaur fossils were found in the Red Marquis Kingdom, and at first they didn't think it was a very valuable thing.

Some people who mine or farm the land can dig up some of these stones from time to time.

"He's well-informed, so let him talk to you."

Liu Zhengchen glanced at Liu Zhang and asked him to give everyone a science popularization.

It also gives them a long insight, and there may be many things they haven't seen before.

Liu Zhengchen felt that Liu Zhang knew everything and could refresh their new understanding of things.

"These insects-looking animals live a long time ago. Not to mention millions of years ago, I only learned about it when I saw a strange book. ”

He had a copy of the scientific anecdote in his hand, which he could show them.

Liu Zhang walked out of the hall on the first floor and went to the carriage to bring the book.

In fact, he was taking something from the subspace watch to avoid their gaze.

After a while, Liu Zhang came over with a thick book.

"Look, is the painting in this book the same as this stone?"

Liu Zhang pointed to the picture of a trilobite fossil, and everyone looked at what he was pointing at.

It is indeed exactly the same, and they believe that Liu Zhang is not lying.

"Can you sell me this strange book? The price is yours. ”

Xiahou Xun felt that most of the records in this book were true, and perhaps it would be of great use to his collection of strange stones in the future.

"I'll give it to you if you want it, this book is not worth much."

Liu Zhang handed the book to Xiahou Xun, and most of the records in it were paleontological knowledge.

He did not bring out scientific books on astronomy, and in the feudal era, it was forbidden for folk research to disseminate astronomy-related books.

Books about astronomy should be read to your family.

Xiahou Xun flipped through the pages of the book, which recorded ancient creatures from different eras.

Although the knowledge is not comprehensive, there are pictures of those paleontological fossils.

Originally in color, Liu Zhang copied several books without color.

It is to make it easier to take it out in the future and share the knowledge in the book with everyone.

"I don't know who wrote this book? It was an eye-opener. ”

Xiahou Xun is curious to know if coral is a plant or an animal? What exactly does it eat?

What is its living environment like? He developed a strong curiosity about corals.

"Is there a book about coral? I want to know more about corals. ”

"Coral is an animal, called a polyp, you see such a big coral. In fact, it has accumulated over many years, which is equivalent to the skeleton of coral, which lives in the sea. ”

Liu Zhang only has a basic understanding of corals, and there are also books about corals.

If Xiahou Xun wanted, he could go to the carriage first.

took out a book about coral from the pressure space watch and gave it to Xia Hou Xun, as for the other books, he didn't plan to take them out.

"Actually, I don't think there's any need to be too obsessed, as long as you have a basic understanding of some things."

Liu Zhengchen's words were said to Xiahou Xun, as a marquis.

We should think more about how to benefit the local people, and personal hobbies are not impossible.

If you are too obsessed, you will fall deeper and deeper.

It may delay the big event, and Xiahou Xun wants to get the book about coral from Liu Zhang.

Liu Zhang got into the carriage again and quickly brought a book.

Some of the knowledge of marine life recorded in the book, if Xiahou Xun wants other kinds of books.

Liu Zhanghui said no, in fact, he still has many books.

Today, I took Liu Zhengchen to see the strange stones and corals, not to send things to others.

"As a token of appreciation, it's up to you."

Xiahou Xun pointed to the strange stones placed in front of him, except for coral, which could not be gifted.

You can send a few stones to Liu Zhang to express your gratitude and return, which is a gift exchange.

Since Liu Zhang doesn't want money, he will give him back in other ways.

"I'll just pick these two."

Liu Zhang picked two ordinary-looking stones, and he could tell at a glance that they were two dinosaur egg fossils.

To others, such a stone is worthless, but to Liu Zhang is priceless.

It's really rare to encounter paleontological fossils in ancient times.

"Then I'll give it to you, do you like such strange stones? Later we can communicate by letter. ”

Xiahou Xun confirmed whether Liu Zhang liked strange stones, maybe they had a common hobby.

"I don't like strange stones as much as yours, I just think it's fun."

He was not a paleontologist, nor was he a geologist.

Collect a few paleontological fossils and study them when you are idle.

Xiahou Xun asked the guards to bring a sulfur stone, which was of little use to him.

He planned to give the sulfur stone to Liu Zhang as part of his apology.

"Yesterday my mother was disrespectful to you, and I apologize to you on behalf of my mother. The other day, I got a sulphur stone, which may be useful to you. ”

After a while, the guard brought two boxes, which felt quite pure.

The box was placed in front of Liu Zhang, and Xiahou Xun opened the box.

In the box was a very pure sulfur stone, which appeared in China very early.

It is recorded in the book "Huainanzi" that sulfur is also one of the alchemy materials.

Liu Zhang had a large amount of saltpeter in his hand, and he got such a large piece of sulfur.

Charcoal is also easy to make, and Liu Zhang also knows how to prepare gunpowder.

If needed, he could configure, with his own hands more powerful explosives.

Of course, he would not supply gunpowder to the imperial court, he wanted to ensure his absolute superiority.

"Such a large piece of brimstone, you have to give it to me. This sulfur can be used for alchemy, and it can also be used to make sulfur soap. ”

Sulfur can be used in many ways, and it can also be used in some medicinal herbs.

"When I bought it, it didn't cost much, just because I apologized for my mother."

Xiahou Xun asked Liu Zhang to accept it, and he also knew that sulfur had some uses.

But it was of no use to him, and he didn't take pills.

"Do you really want to give it to me? If you sell the sulfur to those warlocks, they can use it in alchemy, and they will definitely buy the sulfur stones in your hands at a high price. ”

Although Han Qi teased him yesterday, it was just a trivial matter.

He wouldn't have cared about such a large piece of brimstone.

If you sell it, you can really make a lot of money.

"I don't lack that money, this is my apology for you, and in addition, I will give you some agate."

These things are still valuable to him, I don't know if Liu Zhang likes it or not.

In another box were agate of various shapes, all of which had not been carved.

Everyone thinks that Liu Zhang has made a lot of money today, and two books have won his favor.

I got a huge brimstone and a box of agate.

Although the size of the agate is not large, as long as you take it back and carve it.

To make agate ornaments, the value is multiplied several times.

"Please take these agate, it's worthless."

Because these agates are too small and vary in shape.

Yesterday he thought about it, and still used these agate as an apology.

"You're too polite, I'll ask my wife to get a set of skincare products from the carriage later. You pass it on to your mother, it's an exchange. ”

Wait a while, let Chen Yun go to the carriage to get a set of cosmetics, and bring this agate back to make a few beautiful accessories for his family.

Let them dress up a little more exquisitely, Xiahou Xun may want to be friendly with him.

Now the imperial court is not very strict with the private relations of the nobles, and in a few years.

The imperial court would issue relevant decrees, and the nobles could not make friends with each other privately.

If it is discovered by the imperial court, you may lose your title.

Liu Zhang asked Li Dun and them to carry the box into the carriage, and Chen Yun also followed into the carriage.

There was indeed a set of unused cosmetics on the carriage, and it was considered that some might be given to the ladies of the party.

Chen Yun quickly brought the cosmetics, and everyone saw that the cosmetics packaging she was holding was very exquisite.

The ladies present also wanted a set, and they didn't know how many such cosmetics Chen Yun still had in her hands.
