Annual rings, to be more rigorous, are the concentric rings on the cross section of the stems of perennial woody plants, which are commonly found in trees and shrubs, usually once a year.

The boundary of annual rings is different in different regions. In temperate areas, the boundary of annual rings is obvious in tropical areas. Due to the lack of climate change within one year, the annual rings are not very obvious, but they can also be distinguished.

And in the cold zone, the annual rings will be very clearly visible.

As we all know, the temperature, moisture and other environmental conditions in spring and summer are better, and the plants grow rapidly, and the xylem formed is sparse and lighter in color; on the contrary, the environmental conditions in autumn and winter are harsh, the xylem is dense and darker in color, and the annual rings alternate with the four seasons.

In addition, the trunk faces south and is exposed to sunlight, and the radial growth rate is fast. Therefore, the annual rings on the south side of the stem are wider, and the annual rings on the shady side facing north are significantly narrower.

The trees on the island violated this natural rule, which made the group wonder, but Li Du had a bold guess, that is, the time on the island passes extremely quickly and the climate changes quickly, resulting in the generation of annual rings, but it is very small and almost invisible.

He took a magnifying glass to look carefully and found that the circles were the annual rings. There was also a difference in width between them in the north and south directions, but it was very small and needed to be enlarged before they could be seen clearly.

Most people cannot believe this kind of thing, but Li Du has time and space flying insects, and time and space flying insects can also create such annual rings. Although he has never done it, based on his experience, he knows that this is fine.

In other words, there are problems with the four seasons and time on this island!

After making this guess, Li Du's expression became more serious. The abnormality of the flying insects in the time and space can prove his guess. If his guess is correct, they have to complete the exploration of the island quickly and leave here quickly.

But he couldn't say much, others might not believe his words, and he did not have enough definite arguments to prove his point of view.

Li Du threw the firewood into the bonfire casually. The dark clouds in the sky became denser and the water vapor on the island became heavier and heavier, and it seemed that it was going to rain.

Back in the tent, he took out his watch and looked at it. The watch was still unusable. The time passed on his phone was fine. At the end of the day, everything was normal.

This made him fall into confusion again. He guessed that if it was right, the time point of the mobile phone should not match the reality.

With a lot of confusion, he fell into a deep sleep.

While he was sleeping, Ao suddenly howled again.

Li Du got up and walked out of the tent quickly. He thought he had encountered another crisis, but it didn't work. After everyone came out, it was normal to check everything.

Aao was still howling, turning his head to look south while howling.

Li Du understood and said, "Aao has discovered that Xiaoma takes people to guard the camp. Brother Wolf, let's go!"

Following Aao, they staggered on the mountain. It started drizzling in the sky and moss on the rocks. It was even more difficult to climb up like this, and they would slip and fall down if they were not careful.

After Aao led the way for more than half an hour, Li Du heard a terrified scream: "Wooooooah!"

This voice made him happy, they found their goal!

Li Du shook the searchlight and followed the sound. The light entered a cave and then saw a boy inside.

The boy crouched in the cave and his face was full of horror. He had black hair, his skin color was similar to that of Li Du and his body was wearing a dirty windbreaker. He was the person Li Du was looking for.

Li Du softened the lights and asked in English: "Hello, hello, who are you? Are there any problems?"

The boy was still screaming in horror, holding a stone in his left hand and a dagger in his right hand. The veins on his arm burst out, looking like he was about to collapse.

Ah hungry beside Li Du and looked in curiously. When the boy called him, he also shouted, and shouted at the entrance of the cave: "Aowuwu!"

It is because of this that the boy is on the verge of collapse.

Li Du gave Aao a brain breakdown, dragged it out and stuffed it to Brother Wolf to see, and then continued to ask the boy: "Can you listen to me? Do you need help?"

The boy screamed a few more times, and Godzilla took out a box of chocolate and threw it into the hole.

Seeing the chocolate, the boy first shrank back, and then he gradually calmed down, opened the candy box and started eating.

From this point of view, he is not a savage. He knows how to open the candy box, and he also knows that the chocolate is delicious, and he also has a windbreaker. Li Du guessed that he might be a teenager who ran away from home and was trapped on the island.

After eating chocolate, the boy seemed to understand their kindness and tried hard to climb out.

Li Du and Godzilla helped pull him out and found that his legs were in a strange twist from the knee position, similar to Ah Bai, and his joints were twisted.

The Indian ointment came in handy again. Li Du tore his pants to make Brother Wolf start to correct the bones first, and then applied a layer of ointment.

The boy was surprisingly able to endure the pain. He screamed a few times when he was rectifying his bones, and then applied ointment and calmed down.

Li Du asked, "Can you understand English?"

The boy finally opened his mouth and said something, but Li Du couldn't understand what he said, and his tone was very fast, similar to English, but completely different.

Brother Wolf and others also shook their heads. After hearing this, Big Maklov smiled and said, "Eskimo is one of the Aleutian languages. This is a niche language. It is normal for you not to understand it."

Li Du asked, "Do you understand?"

Big Macklov smiled reservedly and said: "I understand a little bit. The Eskimo language is mainly composed of short vowels, long vowels and mixed vowels. Among them, the short vowels include five a, i, e, o, and u, and the long vowels include..."

Li Du interrupted him and said, "Are you planning to have a live teaching? Translate it directly to me!"

Big Macklov looked awkward and said, "I just understand a little. Eskimo is actually a dialect, and there are many types, and I can't translate it."

Godzilla poured some water for the boy to drink, and asked him to wash his face.

After the boy washed his face, Li Du discovered that although he was a yellow man, his skin was particularly fair, but his skin was relatively rough, just like this small island, revealing a mysterious contradiction.

If both parties cannot communicate, that would be more fucking.

After the teenager was rescued, he seemed to have a good impression of Li Du and his party and kept saying something to them.

Helplessly, Li Du’s side couldn’t understand, and both sides were talking to each other for a while, but they couldn’t understand the other’s meaning.

Finally, Li Du shrugged and said, "Okay, let's go to bed first, let's talk about other things when dawn."

He was about to leave, but the boy grabbed him and then opened his hand and handed him something.

This is a beautiful shell with complex and bright patterns on it.

Obviously the boy gave him this as a gift, so he smiled and received it in his bag.
