After leaving the city, the road becomes difficult to walk.

The bumpy truck and the crowded environment made Yang Rui a little drowsy. The only benefit was that it was relatively warm. The truck itself was fenced. Then tie the air leakage area and blocked it with a thick Green Army coat. It was very comfortable.

Military coats are a must-have equipment for students today. On the one hand, the military coats are made of really good materials, and on the other hand, there are too few choices for winter clothes.

However, Yang Rui wore a British style tweed coat. He had a slender figure and chose British style winter clothes, so he could be comparable to a model or something.

However, in the environment of truck fighting, the British style tweed coat is a little out of place in a pile of military coats.

As a good young man in the 21st century, Yang Rui was a little used to being independent, at least he was unwilling to wear the same clothes as others. However, the good young man in the 1980s seemed to be more considering not leaving the collective.

When we got off the car and a group of people appeared in the wilderness, the effect of this sense of collectiveness seemed to be stronger.

However, Yang Rui has never cared about this kind of thing.

If a researcher stays in the laboratory for a long time, it doesn’t matter if there is anyone around you. When you need to chat, just catch a tiny mouse. If you do it for a longer time, he won’t even deliberately catch the control group.

I will not be sad if I execute you later.

In contrast, botany is a subject that Yang Rui had very few. Although many people would ask him, do you know what kind of flowers/grass/trees/seeds/worms/birds/whip/furs, biologists actually don’t learn these.

Of course, you can't learn it at all. For example, Yang Rui will come to a few field surveys now, but what you can learn is a general concept.

To understand plant taxonomy, it is basically a matter of a botanist. A more accurate name should be a plant taxonomy. Moreover, there are too many plants or biological species on the earth. They are experienced botanists, usually just knowing the fields they are familiar with.

Of course, that's about specific details.

On a large scale, scholars like Professor Xie Gaoyi who specialize in plant taxonomy can tell what it is just a glance at the leaves.

He adjusted the team a little, and then surrounded everyone, followed him, while introducing the passing plants to everyone.

"This is a pine tree, I know everyone, so I won't say much."

"Well, Shan Xing." Professor Xie Gaoyi pointed with his left hand and walked over.

The students behind quickly looked up and began to take notes.

They quickly learned that such notes cannot keep up with the pace.

Because Professor Xie kept spitting out new nouns:

"Arboretum."

"These are all pineapples."

"The shrubs over there are Huzhizi, and there are also small-leafed buckthorn. Hum, they can all be used as Chinese medicinal materials. If they are too far away, they can't get over. Interested students and Master Lin borrow a telescope."

So, the telescope worn by Comrade Lao Li, the forest ranger, immediately became a new hot item.

Bai Ling also wanted to take a look at the telescope, not only because she is studious, but also because the telescope itself is attractive enough.

However, she saw that Yang Rui next to her did not move. After thinking about it, she didn't ask for it. The 25 people looked at a telescope and had to queue up for a while. She would rather follow Yang Rui, even if she was stepping on the snow.

However, Yang Rui saw her movement, smiled, took out a small telescope from his arms, and handed it to her, "If you want to see it, use this one."

The telescope that Yang Rui took out was more than three times thinner than the forest ranger Comrade Lao Lin. Bai Ling raised it with one hand and it was very relaxed. At the same time, the leather sheath also added good friction and made the telescope no longer so cold.

Bai Ling held a telescope with Yang Rui's body temperature and her face turned red. Then she raised it and looked in the direction pointed by Professor Xie.

In winter in the north, there is always a feeling of bleakness in the wild.

But in Bai Ling's eyes, it was a strong and warm tone.

"Yang Rui, did you buy your own telescope?" Squad leader Liu Ping'an slowed down and waited for Yang Rui and Bai Ling in front.

?Yang Rui smiled and said, "I borrowed it."

Liu Ping'an said with a "oh" and said, "Can you use it for the classmates in the class? You won't ruin it for you."

"When Bai Ling finishes reading, you can just watch it." Yang Rui doesn't care who is in his hands.

When Bai Ling heard their conversation, she immediately put down her telescope and said, "Yang Rui, don't you look?"

"I'll look at it later and I'm not very interested in these plants." Yang Rui came with a telescope, which was easy to use. Besides, there was really nothing good to see when I just entered the Badaling Forest Area. Only the rookie who participated in the field survey for the first time would be excited when she heard about the pine.

Seeing that Yang Rui was not humble, Bai Ling handed the telescope to Liu Ping'an and said, "Then I'll finish watching it, you guys can see it."

"Okay, thank you, so you can see faster." Liu Ping'an happily handed the telescope to his classmates, but he raised it up and didn't even look at it, for fear that others would say he was watching it for himself.

There are two telescopes that look at each other, and the alternation speed is naturally much faster, and the queues are all the time less.

At this time, Professor Xie became unhappy and tried his best to say, "Please pay attention to the trees near you. The trees far away can be seen better, but the near is the focus today. Only when the distance is close can you observe the main characteristics of the plants. Well, I'll find an example..."

Xie Gaoyi talked about wherever he thought, and then looked for examples in the woods. He had not taught undergraduates for a while and was a little unfamiliar. But on the other hand, he was also skilled and brave. In the woods, he was still in the Beijing Badaling Forest Area. There were so many materials that could be used for teaching for him.

After walking with his head down for less than two minutes, Xie Gaoyi stopped, opened the marching pot and drank water, and said, "Let's wait for the classmates behind me, I'll tell you how to pay attention to the main characteristics of plants."

After more than twenty people arrived, Xie Gaoyi paid special attention to Yang Rui's position, deflected his body, and said, "Look at the two trees behind me, one is oil pine and the other is black pine. We saw the oil pine as soon as we entered the forest area. I also pointed it out to everyone. Now you can observe, what is the difference between oil pine and black pine?"

College students in the 1980s were very active, and immediately some students raised their hands and said, "The bark of black pine is darker, while the oil pine is a little grayer."

"That's right, that's why black pine is called black pine." Xie Gaoyi nodded and agreed, and said: "The bark of the oil pine is actually a little red. It is easier to identify when the sun is good."

Inspired, someone then shouted in comparison: "The pine leaves of the black pine are thicker."

"That's right, if you compare it, the pine needles of the black pine should be thicker and harder. The pine needles are not only thinner, but also softer and slightly drooping." Xie Gaoyi said as he pulled the pine needles of the pine needles down a little and demonstrated them to everyone.

Yang Rui coughed twice to cover up the sound of almost laughing.

Bai Ling first heard the prelude to laughter, then heard Yang Rui's cough, and couldn't help looking at him with some concern, and laughed: "Be careful of a cold."

"It's okay." Yang Rui replied softly.

In order to avoid harassing other classmates, Yang Rui whispered very close to Bai Ling. The temperature in winter is very low, and the warm breath sprays into Bai Ling's ears, making her feel itchy and happy.

Even if you live in the mountains and forests all your life, you will be very happy if you talk to Yang Rui... Bai Ling thought silently and was about to be distracted.

Xu Anqing's eyes were about to explode when he saw this scene.

It’s not that he has any ideas about Bai Ling, but why does the graceful lady always stare at Yang Rui like this dish? I am also very good, right?

To be honest, Xu Anqing has been not thinking about comparing with Yang Rui for some time, especially after the Lu Boding incident, Xu Anqing ignored Yang Rui even more. He tried not to think about this matter, not to see Yang Rui, and not to read newspapers with Yang Rui's name. So far, everything has been going smoothly.

But he didn't expect that he had reported a field investigation and why he bumped into Yang Rui again? Moreover, the order of queues before seemed to be disrupted.

Xu Anqing can accept that Yang Rui is better than himself in academics, but it is no longer possible to not accept it. However, in terms of male charm, Xu Anqing still has a certain degree of self-confidence. In any case, Yang Rui's family is just a small township cadre, which is incomparable to the birth of his high-ranking officials. A girl with a little ambition should be more realistic.

However, he did not expect that Bai Ling, a girl in this class, had been fooled by Yang Rui, and no longer looked at others.

"Professor Xie, I think the difference between black pine and oil pine is the most obvious." Xu Anqing raised his hand angrily. His observation ability is better than that of ordinary people. Although he is in a turbulent mood, it is still very stable to play with everyone to find fault.

Professor Xie nodded to Xu Anqing and said, "Yes, for black pine and oil pine, there are new buds on the top of their branches every year. The colors of the buds are different. It is winter now and it is not very obvious. But if you look closely at these two trees, you should still find the pine buds that have not yet been fully developed."

He pointed to both sides and said, "You see, the pine buds of the black pine are white, and the pine buds of the white pine are brown-red, so the black pine is also called the white pine. This is the biggest similarity and similarity between the two trees, and it is the absolute criterion for judgment."

Students looked at it one after another, and some people opened the notes and took notes. Now there is no Internet, and fragmented knowledge can only be recorded and sorted out by themselves. Otherwise, it would be very difficult to find a specific and subtle Chinese book.

Professor Xie has a good impression of Xu Anqing. He stood behind him and said with encouragement: "In our plant taxonomy, discovering groups, or re-dividing groups through research, is one of the most important tasks. If you want to make a difference in this regard, you must have the same observation ability as this classmate. With so many plants, it is hard to say whether there are new species that have not been discovered yet, or even new groups. How to find them? We have many scientific methods now, but the role of human beings is still the most important. We are all elite students of Peking University. I hope that some of you will one day discover new species and determine new groups. Therefore, students who are interested in this will cultivate their keen observation ability from today on."

The students nodded one after another, and Xu Anqing's eyes even shone with light, as if he had seen a path to defeat Yang Rui, or at least a curved victory over Yang Rui.
