Sophie has to go to work, and Li Du takes Ah Yan outside. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

There is a big lawn in the hospital, and many people are recuperating, so he took the puppy to the grass, and the puppy was shone by the sun and blown by the wind, as if he had been given an excitant drug, and immediately came to his senses.

Don't look at Ah Yan's little short legs, it is not good to run soon after he was born, but he is still very majestic on the lawn.

It's just that it's too small, the lawn is uneven, and there are potholes in some places, so it's easy to run and fall into it entirely.

He is young, small, and his legs are weak, and once he falls into the pit, he can't get up, so he can only scream and scream there.

At noon, Li Du invited Sophie to a meal.

There is a music restaurant in Flagpole City, which is very upscale, and it is full of small private rooms, and different private rooms have different music playing.

The two chose a piano music room, Sophie explained the piano music to him, and Li Du introduced these dishes to her, and she was very happy to eat.

In the afternoon, Hans called Li Du and said: "I contacted a home furnishing hall and they have experts in mahogany, and I would like to ask them to identify the wood." ”

Li Du was also concerned about this, and he first went back to the room of the crown of pines to look at the treasures he treasured, and then returned to the camp.

Among the treasures in his collection, the most valuable is probably the Trossi-Leggenda watch he wears on his hand, which he does not have to worry about being stolen, because he always wears it on his hand.

The second is the jeweled saber he scavenged from the Arabs, which is inlaid with beautiful precious stones, with a sharp edge and a refined material, and the handle and scabbard are made of ivory.

However, what really doubles the value of this knife is its owner's identity, Li Du has seen it using the ability to reproduce time, and the owners of this knife are either rich or expensive.

The last of these owners, whom he often sees in the news, is Libya's supreme leader, Omar Muammar Gaddafi.

He can find the knife even without the Bug's ability, and in some news about Gaddafi, his desk is sometimes displayed, with the knife in the center of the desk.

It's a pity that there is no introduction to this knife on the Internet, and Li Du estimates that it is not a legendary knife, but because of the use of a large number of rare materials, it was collected by Gaddafi.

In addition, there was papyrus that he did not understand, the words on which he had not yet deciphered, and he did not know what was written on them.

These three things were privately collected by him, and there was an upright specimen of a dodo skeleton on the table.

It was almost out of his possession, but he was satisfied with the idea that a specimen could be worth a million dollars.

By the time he arrived at the camp, the mahogany experts had arrived, a middle-aged Chinese man and an old white gentleman, who had brought tools to the camp.

Hans introduced them and said, "This is a fellow citizen named Antonio Sue, whose family has been working on mahogany. And this gentleman is named Bart Kerry, who is an expert in wood and furniture. ”

Li Du shook hands with the two, and Antonio Su asked in awkward Chinese: "Mud howl, Li, very engaged in the mud, my foot fortune Laizi Jiangnan." ”

His Chinese made Mr. Li listen to the cold, Mr. Li introduced himself, and then opened the wooden box, revealing the trunks inside.

Seeing these tree trunks, the two men looked at each other and nodded at the same time.

Seeing this, Hans happily asked, "The results are optimistic?"

"It needs to be identified, but on the outside, the results are very positive," Bart said. ”

Li Du asked, "What can you see from the appearance?"

Antonio explained, "These woods belong to different varieties of mahogany, and as you may know, there are thirty-three varieties of mahogany, which are different in appearance. ”

"Take this," he said, pointing to a section of purple-red trunk, "this one looks like red sandalwood, and it looks like Indian small-leaved red sandalwood, a very precious species." ”

Li Du said: "I have been learning this knowledge recently, but as far as I know, the African red sandalwood looks very similar to this. ”

Antonio smiled and said, "With all due respect, you may have learned knowledge, but you are still inexperienced. The color of Indian small-leaved red sandalwood is red at first, and then it becomes darker. Compared with African rosewood, there are patterns in purple, and the oil is not dry. ”

"African red sandalwood is purple-black, without luster, coarse fibers, and has a lot of cow hair lines after drying and shrinking, which is very ugly. ”

"If you say a little mysterious, it is the same red sandalwood, the small leaf red sandalwood is a living wood, and the other red sandalwood is dead. ”

When Antonio introduced, Bart went into action.

He consulted with the two of them, and with permission, took a small piece from each trunk and divided it into smaller pieces again for different treatments.

He took a small piece of each and put it in a small beaker, added some solvent to it, and slice some of it under a microscope, and processed it in a variety of ways.

Hans was surprised when he saw it, "Is it so complicated to check?"

Bart laughed, "Of course, it will take five or six hours." ”

Hans looked at Li Du and said, "All of us don't know much about mahogany, and it turns out that we were stupid when we were in Holbrook. ”

Some of them called their friends to describe it, some took photos to show their friends, and some made videos, thinking that this would tell the true identity of the rosewood.

It turns out that these methods are very low-level and unreliable.

The most precious of the rosewood is the small-leaved red sandalwood, and the first thing the two of them began to inspect was the purple red wood.

Bart took out a piece of white paper, he took a piece of wood, scratched it on the white paper, and drew more than ten bars in a row, all of which had traces of purple red, and the first to the last, the traces remained unchanged.

Li Du asked, "Isn't it possible to determine its identity in this way?"

Bart laughed: "Sir, you don't know how sophisticated the counterfeiting technology is now, and you can fake this by soaking some wood with a reagent of potassium permanganate mixed with iodine and litmus. ”

As he spoke, he chopped some sawdust from the wood chips, put them in a glass with water, and said, "We can wait, and we will use fluorescence detection to identify them later." ”

"It shouldn't be a big problem. Antonio, who was observing in front of the microscope, looked up and said.

Li Du leaned over to the microscope and looked at it, and the cross-section of the wood and the fiber pattern were magnified many times in the lens.

He couldn't see anything, but for Antonio and Barth, who were in contact with wood every day, there was so much information coming out of the microscope.

Antonio is a good teacher, and said: "This is the thirty-fold mirror, which is the most authoritative method of judging the information of mahogany in physics, of course, it must be combined with other physical methods, do you want to know?"
