Sophie was going to work, and Li Du took Aao outside.

There was a large lawn in the hospital and many people were recuperating. He took the puppy to the grass. The puppy was shining by the sun and blown by the wind. It was like taking hyperactants and immediately became energetic.

Although Ah Ao's short legs are not smooth enough to run shortly after he was born, 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 fall into it as it runs.

He is young, small in size, and has no strength in his legs. Once Ao falls into the pit, he can't climb up. He can only scream there, screaming non-stop.

At noon, Li Du invited Sophie to have a meal.

There is a music restaurant in Flagstaff City, which has a very high-end style. It is full of small private rooms, and different private rooms have different music playbacks.

The two chose a private room for piano music. Sophie explained piano music to him, while Li Du introduced these dishes to her and had a great time eating.

In the afternoon, Hans called Li Du and said, "I contacted a home furnishing restaurant. They have experts in mahogany. I want to ask them to identify the identities of these woods."

Li Du was also very concerned about this. He first returned to the room of the Crown of Pine Tree to look at the treasures he had collected, and then returned to the camp.

Among the treasures he collected, the most valuable one should be the Trossi-Leggenda watch he wore on his hand. You don’t have to worry about being stolen because he has been wearing it on his hand.

The second is the gem saber he got from the Arabs. The knife is inlaid with beautiful gems, sharp blades, exquisite material, and the handles and scabbards are made of ivory.

However, what really doubled the value of this knife is its owner's identity. Li Du has seen it with the ability to reproduce time. The owners of this knife are either rich or noble.

The last master he often sees in the news is Libya's supreme leader Omar Muammar Gaddafi.

Even without using Xiaozhu's superpower, he could find the figure of this knife. In some news about Gaddafi, his desk sometimes appears, and the knife is placed in the center of the desk.

Unfortunately, there is no introduction to this knife on the Internet. Li Du probably is not a legendary sword. It is just because it uses a large number of rare materials that it is collected by Gaddafi.

In addition, there is also papyrus that he doesn't understand. He has not interpreted the words on these papers so far, and he doesn't know what is written on them.

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

This thing almost doesn't belong to him, but he was still very satisfied with it when he thought that a specimen could be exchanged for one million US dollars.

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

Hans introduced them and said, "This man is a fellow countryman named Antonio Sue, whose family has been engaged in redwood research. And this gentleman named Bart Kerry, an expert in wood and furniture."

Li Du shook hands with the two, and Antonio Su asked in awkward Chinese: "Mi Yu, Li, it's very good at being a good person, my best fortune is Lai Zi Jiangnan."

His Chinese made Mr. Li feel so sad. Mr. Li introduced himself, and then opened the wooden box to reveal the trunks inside.

Seeing these trunks, the two of them looked at each other and nodded at the same time.

Seeing this, Hans asked happily: "The result is optimistic?"

"It needs to be identified, but from the outside, the results are optimistic."

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

Antonio explained, saying, "These woods belong to different varieties of mahogany. Maybe you know that mahogany is divided into thirty-three types, and they vary from appearance to appearance."

"Take this one," he pointed to a purple-red trunk road, "this looks like a red sandalwood, and it looks like a small-leafed red sandalwood, a very precious tree species."

Li Du said: "I have also been learning this knowledge recently, but according to my knowledge, the African Rosewood looks very similar to this one."

Antonio smiled and said, "I am blunt, you may have learned knowledge, but you still lack experience. The color of Indian small-leafed red sandalwood was red at first, but the color behind it gradually became darker. Compared with African red sandalwood, there are patterns in purple and they are not dry."

"African rosewood is purple-black, with no luster, thick fibers, and has a lot of cow hair patterns after drying and shrinking, which is very ugly."

"If it is a bit mysterious, it is that they are both red sandalwood. Small-leafed red sandalwood is a living wood, while other red sandalwoods are dead."

When Antonio introduced, Bart began to act.

He solicited opinions from the two people, and after obtaining permission, he cut a small piece from each tree trunk, and then divided it into several smaller pieces for different processing.

He took a small piece of each type and put it in a small beaker, added some solvents to it, and some were sliced ​​under a microscope, with various treatment methods.

Hans was surprised when he saw it, "Is the examination so complicated?"

Bart smiled and said, "Of course, it will take five or six hours."

Hans looked at Li Du and said, "We all lacked understanding of redwood. It turned out that we did a stupid job when we were in Holbrook."

Some of them called their friends to describe, some took photos for their friends to show, and some conducted videos, thinking that this would allow them to distinguish the true identity of Redwood.

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

The most precious one among the mahogany is the small-leaf red sandalwood, and the first one the two of them started to test was the purple mahogany.

Bart took out a piece of white paper, he took a piece of wood, and scratched it on the white paper, and drew more than ten bars in succession, with purple-red marks, and the traces remained unchanged from the first to the last one.

Li Du asked: "Can't it be determined by this?"

Bart smiled and said, "Sir, you don't know how advanced the counterfeiting technology is now. You can fake this by soaking certain wood with reagents mixed with potassium permanganate and litmus solution."

As he said that, he chopped some wood chips from the wood chips and put them in a glass cup filled with clear water, saying, "We can wait, and we will use fluorescence detection to identify them later."

"It should be no big problem," Antonio, who was observing in front of the microscope, raised his head and said.

Li Du came to the microscope and looked at it. The lens contained many times the cross-sections of wood and fiber patterns.

He couldn't see anything, but for Antonio and Bart, who were exposed to wood every day, there was too much information revealed in the microscope.
