Along the way, the various rare animals and plants that they encountered made the pace of the expedition team slow down from time to time, busy recording, taking pictures, collecting samples, and making specimens.

Because the expedition team is not poachers, it is unlikely that they will carry guns to knock down wild animals and then return with the carcasses to study them slowly. Therefore, when encountering various animals, Han Zhengbao and others mostly took pictures of the animals that appeared with their cameras from a distance, and tried to record the breeds and numbers of these animals. Once those animals burrow into the forest, the expedition team that can't catch up can only watch these national second-class protected animals in the depths of the dense forest.

However, the plant group led by Xu Wenchang is a bit complicated, after all, once the plants are discovered, they can't run away.

Once some uncommon plants are found on both sides of the road, even if it is not a national protected plant, Xu Wenchang and others have to make detailed records, take pictures, and make simple specimens.

Following Xu Wenchang, Liu Rui learned a lot of plant knowledge, originally some of his common plants, after Xu Wenchang and Fu Xiaoqiang's explanation, Liu Rui finally knew its original scientific name, use and survival status.

Take the lacquer tree as an example, it is not uncommon in Xiaoqingshan District, but only a few villagers will use it, and many villagers do not know that the lacquer tree has huge economic value and is an important special economic forest in China. The reason is that some people are allergic to lacquer, and once they are contaminated with lacquer, their skin will be red and swollen, itchy and unbearable, so they will be shunned.

But in reality, lacquer is an excellent preservative and coating; The fruit of the lacquer tree can be used to extract oil, the bark can be used to make wax, and the wood can be used to make furniture and decorative materials. It can be said that the lacquer tree is full of treasures all over the body, and as long as it is used well, it can create great wealth.

"Mr. Xu, these lacquer trees are so precious, is it possible to cultivate them artificially?" Listening to Xu Wenchang explaining the situation of the lacquer tree, Liu Rui couldn't help but be interested.

Around Liang Village, there are many barren mountains, overgrown with miscellaneous books, shrubs and weeds, which usually do not produce any economic value except for the villagers going up the mountain to graze cattle and sheep. Over the years, the villagers have planted orchards on their own hills, and the profits have not been very good, so these barren mountains are even more uncared for.

Now seeing that these lacquer trees have such a high economic value, Liu Rui can't help but feel a little moved.

Since deciding to stay at home and not go to school, Liu Rui has put his mind on the village and began to have a bit of a taste of the League branch book. If this kind of lacquer tree can become a promising economic forest, it is also a good choice to plant in the barren mountains around Liang Village. In addition, the leaves of the sumac tree turn red in autumn, making it a beautiful sight.

"In the 70s, the forestry department had already planted a large area of mixed forests of lacquer and Huashan pine with aircraft sowing in Fujian, and also built a lot of artificial bases." Xu Wenchang paused and said: "It is theoretically feasible, but after you go back, it is best to investigate the local climate, soil, light, etc., to see if it is suitable for the large-scale planting of lacquer trees." ”

A few days ago, Xu Wenchang was bitten by Zhu Yeqing, but because of the proper emergency treatment, he took the antidote pills provided by Liu Rui, and after two days of treatment and rest in the hospital, he recovered and was discharged.

This large-scale scientific expedition is rare, so Xu Wenchang naturally will not miss it easily, he still joined Liu Rui's group and moved towards the depths of Xiaoqingshan.

Xu Wenchang has a lot more work to do than other scientists, because every time he encounters a plant with a representative surname, he has to stop to record data, collect samples and make specimens.

Since gradually leaving the scope of the plantation, the various rare plants in the primeval forest have begun to dazzle Xu Wenchang and be overwhelmed. Fortunately, his student Fu Xiaoqiang is very diligent and his work ability is not bad, and Liu Rui, a supernumerary assistant, can also cope with it.

Thinking of this, Xu Wenchang couldn't help but look at Liu Rui and sighed a little.

During this period of time, Liu Rui has grown rapidly from a high school student who doesn't know anything, at least the technology of making plant specimens is no less than Fu Xiaoqiang. Of course, because of the lack of knowledge, Liu Rui knows many things but doesn't know why, but it doesn't prevent Liu Rui from doing things well.

After listening to his explanation of the situation of the lacquer tree, Liu Rui could still think of whether the lacquer tree could be used for artificial cultivation to create greater economic value for the villagers. Liu Rui's deeds, Liu Rui's thoughts, the teachers of the inspection team saw it in their eyes and remembered it in their hearts.

To be honest, it is precisely because of the shining points that gradually appear in Liu Rui that several teachers in the inspection team are more and more favored by him and are willing to get close to him. Originally, Xu Wenchang didn't need to explain to Fu Xiaoqiang at all, but in order to teach Liu Rui, let him know more.

Not only Xu Wenchang is like this, Yu Shanwei and Han Zhengbao have also taken good care of Liu Rui since then, and they no longer just regard Liu Rui as a supernumerary, but gradually see him as a new student.

After Xu Wenchang put the specimen of the lacquer tree into his backpack, the team continued to set off.

As the sun continued to move, the scorching sunlight that had been shining on the body was gradually blocked by the mountains and forests, bringing a burst of shade.

Liu Rui looked at the waterproof watch on his wrist, the time had already pointed to more than four o'clock in the afternoon, and it seemed that it was time to find a campsite.

Although there are veterans like Wang Huaan in the team, Liu Rui still wants to use his brain to determine where there is a place to camp nearby. After all, I will always have the opportunity to read into the mountain in the future, and there will be no progress if I always sit back and enjoy it.

Just when Liu Rui was still in a lot of surroundings, Wang Huaan had already found a suitable place, brandished the machete in his hand, and led the team forward.

It is a large, flat mountain rock that juts out halfway up the mountain, forming a platform that stands out rather abruptly in the depths of a dense forest.

Wang Huaan walked around, looked at the mountain stream under the boulder, and found that the traces left by the flood were still more than ten meters below, and beckoned the team to come over, and camped here tonight.

In the forest just now, because of the distance, Liu Rui didn't think how big this boulder was, but now as soon as he got closer, Liu Rui found that this boulder could really be regarded as huge. The boulders, which are more than ten meters long and wide, are half-suspended halfway up the mountainside, and the babbling stream is below the mountain, surrounded by lush forests.

Liu Rui didn't know how such a large boulder appeared in a dense forest, flooded or crustal?

However, the whole team was very happy to find such an excellent campsite, after all, it is not easy to find a suitable camp in the dense forest.

Just as everyone was unloading their suits and preparing to set up tents and camp, Xu Wenchang's eyes were fixed on the river valley below the boulder.

"Old Han, come and pinch me, am I dreaming?" Xu Wenchang couldn't believe what he was seeing, and turned his head and shouted at Han Zhengbao.

"What's wrong?" Han Zhengbao was a little puzzled.

Han Zhengbao knows his old buddy very well, and knows that he is not a person who is easily excited, could it be that he saw something great?

Taking two steps forward, Han Zhengbao looked in the direction of Xu Wenchang's finger and found that a forest was growing at the foot of the boulder that was completely different from the surrounding vegetation.

The large leaves protrude from the trunk of the tree like huge palms reaching out to the sky, and the serrated feathered leaves glowing with wax and light contrast with the delicate leaves of other trees around it.

"Alder?!" Han Zhengbao and Xu Wenchang glanced at each other and said a noun in unison.

180 million years ago, alder was once the most abundant plant on Earth, and it and dinosaurs were called the two major symbols of the 'reptilian era' by scientists. With geological changes and changes in the environment and climate, people can only see dinosaur fossils in museums. Although it is not extinct, it can only be seen in some inaccessible ecological shelters.

As far as Xu Wenchang can see, the area of this alder is at least dozens of acres, and hundreds or thousands of alders are densely scattered in the river valley area, which is very visually impactful.

Xu Wenchang never thought that on the first day after entering the mountain, there would be such a huge discovery!

Because there are a lot of wild forests in the wild in Sichuan, Hubei and other places, although they are national first-class protected animals, the impact on Xu Wenchang is far from enough.

According to Xu Wenchang's understanding, most of this tree-shaped alder survives in the tropical and subtropical rainforests of Xishuangbanna, Honghe, Wenshan and other places in the wild. Most of them are scattered in the forest or in the shade of the valley, at most dozens of trees form a dominant community, and the existence of large alder forests is rare under natural conditions.

However, the alder in front of him subverted some of Xu Wenchang's understanding, but he was quickly relieved that nature was so magical, and his knowledge was not enough.

Xu Wenchang calculated in his heart that the current location was at most ten kilometers away from Shangliang Village, but because it was inaccessible, this piece of alder had not been discovered by them until now. Perhaps, the mountaineers who hunted and collected medicine in this vicinity had already seen it before, but they did not know the scientific research value of Alder, so there was no news to spread.

Just on the first day of entering the mountain, he gave Xu Wenchang such a huge surprise, and he was a little overwhelmed. As previously judged, the Xiaoqingshan area is a huge natural treasure trove, and it is imperative to protect it.

Perhaps, the rest of my life will be indissoluble with this magical mountain range.

In the future, after the establishment of the nature reserve, the countless rare plants here alone will be enough for Xu Wenchang to conduct decades of research. With these abundant resources, Xu Wenchang is confident that he will come up with more research results and provide effective protection solutions for some endangered plants.

The first day after entering the mountain, there were many surprises!
