Yun Yi was stunned for a moment, yes, if the land is leveled a little, then the ultralight aircraft made by Chen Wei can take off and land here.

In this way, it is not only much more convenient for people to go up the mountain, but also for transporting materials to the mountain.

After all, although it takes more than two days to walk from the bottom of the mountain to Taiping Valley, the actual distance is definitely not more than 30 kilometers; If you count the straight-line distance, it is only about ten kilometers at most; Let the ultralight aircraft deliver the supplies, and it will only take twenty minutes at most to fly from the bottom of the mountain to the Taiping Valley.

I should have thought of this question a long time ago, but I didn't think of it because my brain was a little rigid; Professor Alfred, on the other hand, is not, like helicopters and small planes, which are essential tools in scientific exploration and exploration in the United States = China, and naturally Professor Alfred can think of it.

Secretly wrote down this matter, and a group of people with backpacks and firewood set off for the first line of sky.

"Oh God, I didn't think there was such an ancient tree here!"

When everyone had crossed the sky, Professor Alfred was immediately shocked by the desolate ancient trees in the distance, and immediately ran towards it with a trekking pole.

"Hey, watch out for Professor Alfred, there's snakes everywhere!"

Yun Yi hurriedly grabbed the professor, and then took a hiking pole and pulled it twice in the bushes, and sure enough, a colorful poisonous snake was picked out by Yun Yi and killed.

"Hey, I said Yunyi, you can't kill wild animals like this, especially this poisonous snake; Oh my God, what did I see, here I saw the patterned snake that can only be found in the tropics! ”

Professor Alfred suddenly exclaimed, and Yun Yi smiled:

"Professor Alfred, don't be surprised, this is a tropical climate!"

As he spoke, Yun Yi pointed to a bush not far away. It is the ultra-broad-leaved form of tropical plants.

"It is surrounded by mountains, and apart from this gap, there is not a single mountain road in the whole valley that leads to the outside world; The terrain is such that the cold snaps of winter cannot blow it down; And most importantly, there are plenty of hot springs, which keep the temperature at a minimum of more than 10 degrees Celsius all year round! ”

Yunyi's explanation surprised Alfred, a half-geologist; Although he had walked through a lot of unique terrain, it was the first time he had seen the terrain here in Qingyun Valley.

Biologists in general, and especially animal specialists who study biological habits, are usually also semi-geologists because they study geography and climate. It has a very important impact on the habits of living things.

Entering the Yinyang Valley, everyone put down their luggage, and after a little rest, Professor Alfred could test the soil composition.

From the morning to the evening, Professor Alfred took samples of the soil in the Yinyang Valley, an area of about 156 square meters, one by one, and then compared the soil samples collected by Yunyi from other places, and finally told Yunyi with certainty that the soil composition in the Yinyang Valley is very suitable for the growth of tea trees.

"That's great!"

After hearing Professor Alfred's report on the last soil, Yun Yi immediately breathed a sigh of relief. The climate and environment of this Yin Yang Valley are undoubtedly very suitable for the growth of tea trees, and the soil is also suitable, which finally makes him no longer worry.

Yin Yang Valley is the outermost valley mouth of Qingyun Valley, and the total area here is about fifteen or sixteen square kilometers. If the tea cultivated in the Yunyi space is gradually planted according to the plan, then at least this is more than 10,000 acres of excellent tea, which is enough to make Yunyi become the top tea producer in China in one fell swoop.

It won't take many years, Yunyi believes that after the expansion of his tea garden step by step. Like what West Lake Longjing, Maojian, and Da Hong Pao will all be scum in front of their own tea gardens in the future!

At this time, it was almost dark, and a group of helpers brought by Yunyi, under the command of Miao Lao Cannon, had already set up a tent. Enough branches have been collected; After Miao Lao Pao arranged the order of the night vigil, everyone was able to fall asleep.

When Yun Yi was woken up, he looked at the time, it was already ten o'clock in the evening, and from ten o'clock to eleven o'clock, Yun Yi was in charge of the vigil.

I have to say that although the temperature in Qingyun Valley is very high all year round, because of the high humidity here, there will be a feeling of dampness and cold at night; Yun Yi felt a little cold after getting up, and hurriedly sat down by the fire.

"Woo!"

Xiao Bai, who had been guarding outside Yunyi's tent, immediately came over, lay on Yun Yi's lap and continued to sleep, Yun Yi gently rubbed Xiao Bai's head with one hand, and slowly added branches to the fire with the other.

At eleven o'clock in the night in the Yin Yang Valley, not far away the thousand-year-old trees in the dark night with their teeth and claws, looking particularly hideous, the tall trunk cracked one by one, as if a ghost in hell was crying, Rao is Yunyi is very bold, looking at those ancient trees still have a burst of scalp numbness.

"Your sister, she looks so stumbling, Lao Tzu will definitely cut you down in a few days, making you look ugly and scary!"

"Woooooo

Just when Yun Yi lowered his head and thought about his thoughts, Xiao Bai, who was suddenly lying on his lap, suddenly jumped up and whined at the place where the Yin Yang Valley and the eagle's beak ditch were connected in the dark night.

"Woohoo!"

With Xiaobai's barking, Xiaobai's brother, Miao Laocang's sunspot also whined at the night, and a group of hunting dogs paused for a moment, and suddenly barked desperately into the night.

"What's wrong?"

Miao Lao Cannon rushed out of his tent with a gust of wind, and ran to Yun Yi's side in two steps and asked, those sharp eyes stared at the place where the hounds were barking, and the earthen gun in his hand had already been gunpowdered!

"I don't know what to say, just now Xiaobai suddenly screamed, I think it should be a big guy, otherwise Xiaobai wouldn't be so like a big enemy!"

Yun Yi's brows were furrowed very tightly, Xiao Bai's expression was very serious, this was the first time he had seen Xiao Bai with such an expression, even if he fought with the grassland sloth in the Northeast Underground Mausoleum last time, Xiao Bai was not so like facing a great enemy.

"Whoa!"

Xiao Liang was also awakened from his sleep at this time, and immediately crawled to Yun Yi's side with a fierce momentum, and shouted side by side with Xiao Bai into the night, as if that guy would beat him when he came over.

The third pig is also a fox and a fake tiger squatting beside Xiaobai, screaming at the night, but the leopard cat prince jumped up to a big tree not far from the side without saying a word, looked over there, and suddenly screamed sharply, as if he saw something terrible.

"Meow ——!"

As soon as the prince's mournful cry sounded, the little boy who was roaring arrogantly suddenly sniffed his nose in the air, and suddenly shrank his head suddenly, and immediately got into Yunyi's tent, as if he had smelled some terrible smell.

"Whew,"

"Woooooo

A group of hounds also whimpered lowly, and they all trembled with fright, lying on the ground with their tails between their tails and no longer daring to bark, only the two brothers Xiaobai and Heizi still did not bark timidly into the night, and the third pig was honestly silent.

"Squeak!"

Wukong, who didn't care at first, also squeaked loudly in horror, and quickly climbed up a tree next to him, but this guy looked at Yunyi, hesitated for a moment, and then climbed down from the tree to stay by Yunyi's side.

"It looks like a big worm, otherwise these dogs wouldn't be so scared!"

Miao Lao Pao and several other old hunters looked at the night with solemn expressions, several people all picked up their hunting = guns, and Yun Yi also opened the insurance of his hunting = crossbow.

"It's strange, even if the average big insect sees a hunter entering the mountain, it rarely takes the initiative to come over to find trouble, what's going on with this big insect?"

Several old hunters looked in the direction of the eagle's beak ditch suspiciously, and at this time a breeze was faintly blowing from that side, and the smell of the wind was getting stronger and stronger for them to understand that the distance between the tiger and everyone was constantly shortening.

"Oh, Mr. Yun, what's going on, did you encounter a large carnivore?"

Professor Alfred finally found his eyes and asked as he crouched beside Yun Yi in a panic.

"Congratulations, professor, it seems that we have really encountered a fierce beast, and it is the largest fierce beast in China = the south of the country - the South China Tiger!"

Yun Yi smiled slightly, although it was quite unlucky to meet a tiger, but if you want to come here in this province, except for the legendary South China tiger, it seems that there are no other tigers.

Others can't find the South China Tiger when they play with their lives, and they accidentally encountered it, it seems that this luck is really not ordinarily bad!

"Woooooo

Xiao Bai once again made a warning sound in the night, obviously the tiger was still close when he heard Xiao Bai's warning sound, which made Xiao Bai angry.

"Whoa!"

On the other side, a roar that shook the mountains and forests came over, and the sound was extremely powerful, with a sense of dominating the world, which made Yunyi and the others feel shocked and their hearts fluttered, and countless cold hairs on their backs trembled, and the anus = door tightened for a while.

With this roar, a tiger finally emerged from the night and walked less than two hundred meters away from the camp of the people.

"Bang!"

The hunting = gun in Miao Lao's gunner rang out, blowing up the entire night sky.

But what frightened everyone was that the tiger did not hesitate and continued to slowly press towards the camp.

"Something is wrong, what's going on with this big worm, why did you take the initiative to find trouble with people?"

Miao Lao Pao and a few other old hunters suddenly frowned very tightly, although they had not killed a tiger, but from their father's mouth, they all knew that this tiger would not take the initiative to attack people, and even if they were very hungry, they would not find trouble with people, because this smart thing knew that the Daoist people were much more powerful than them.

Facing the cold eyes of a fierce tiger, everyone's hearts were heavy! (To be continued......)
