Luo Daxi saw that Li Hao and Meng Fan's faces became solemn at the same time, and he also became interested in weeds, so he cut a plant and took it in his hand to look at it carefully, but after looking at it for a long time, he didn't see anything wrong, so he asked Li Hao: "What's wrong, mouse?" Is there something wrong? Isn't it just a little thicker? ”

Li Hao raised his head and glanced at Meng Fan, and then said to Luo Daxi: "This is an annual herbaceous plant, and if you look at the broken section of the grass stalk in your hand, this grass is at least six years old." After speaking, Li Hao confirmed to Professor Wang: "Yes, Professor Wang, what you just said can't be this aspect." ”

Professor Wang said: "That's right, I just said it's impossible. This weed is distributed in most parts of our country, and it dies every year, and the seeds germinate and grow again the next year, and in this great northwest region, the natural conditions of winter are even worse, and it is impossible to survive the winter anyway, and this grass is as you said, it is six or seven years old. What the hell is going on here? If I hadn't come here to see it with my own eyes, who would have said that I wouldn't believe it, it seems that my old king's life has been in vain. ”

Professor Wang and the others had no answers in their hearts and were full of doubts, but Li Hao began to have some clues in his heart, shouldn't the golden beans planted in Guiguzi also be annual? My father said that it took decades to grow, so this ruins must be inseparable from Guiguzi, and it is definitely worth it for me to come this time, even if there is any danger, I have to explore it.

"Let's go, let's keep going, the terrain here is getting open, we can't go in the middle, let's continue along the valley floor on the left. Daxi, find two long branches to open the way. Li Hao commanded.

When Luo Daxi heard this, he hurriedly retreated to the edge of the forest, looked at a few branches to make a pathfinder stick, and gave Meng Fan and Xiaoxian one each, while he and Li Hao walked in front and beat down the weeds with the stick to open the way. Since Li Hao had a stick to make a spear last night, it was easier to use it to open the way, and he soon came to the side of the valley.

The mountains on both sides are not hard stones, but gray-white sandstone, which has become very loose after tens of thousands of years of weathering, and a heavy rain on the bare stone cliffs may cause a large area of loose stone to slide, so a few people do not dare to get too close to the cliff edge. Due to the proximity to the side of the valley, the geology does not have as much soil as in the middle, so the weeds become sparse and the walk is much easier. After walking forward like this for more than 20 minutes, the real canyon made a big turn, and after turning around, it became a large plain under a mountain cliff, close to the geology outside the canyon, there was almost no soil on the surface, it was sandy, and the strange thing was that there were no patches of weeds on the plain, but clusters of clusters together, as if they were tied up and piled together.

While Li Hao was still wondering how the weeds had suddenly become like this, Meng Fan patted him on the shoulder with his hand behind him and said, "Look over there." Following Meng Fan's gaze, there was a huge chimney-like thing erected in front of him in an open area, and since they were walking on the left side of the valley, if they had gone to the right, they would have found this towering thing long ago.

Several people looked at this strange chimney from afar, rising from the ground, like a cone made of earth, with a diameter of about eight meters at the bottom, and a height of more than forty meters, as high as a ten-story building, which seemed extremely abrupt on this small plain.

"What's that?" Luo Daxi couldn't help but ask at first, then looked at Li Hao, Li Hao also looked as surprised and puzzled as him, and then looked at Professor Wang, his face was surprised and delighted, and it seemed that he already had an answer. "Old man Wang, what is that, tell me quickly?"

Professor Wang was stunned for a while, then turned his head to look at Luo Daxi, and then looked at the other people with expectant looks, and said to Meng Fan: "Tell me about it, I'm going crazy." ”

Meng Fan smiled and said, "I'm going crazy too, okay, I'll tell you." The front of this towering mound building should be a termite nest. Termites living in hot and dry areas will accumulate huge ant nests on the ground to facilitate air circulation and cooling, their nests are like a large mound, the tall appearance is easy to identify, and the ant nests are not only the one on the surface, they also extend deep into the ground, because most termite nests are located in a very dry area, and the construction needs moist soil to accumulate the ant nest, in order to find the soil that meets the requirements, termites will dig down 30 meters or more to find the water table, Hold the fastened clay or moist rock you find in your mouth and pile up the outer layer of soil on top of it. Most of the anthills are three or four meters high, and some people have found as high as 20 meters, and it is the first time that they are so huge in front of them, and these anthills are basically in African countries, China and very rare. ”

Everyone was completely shocked when they heard that the huge mound in front of them was an anthill, but Professor Wang smiled happily: "This is great, there is just a problem they helped me solve." ”

When everyone heard Professor Wang say such a sentence, they looked at him suspiciously, and saw him say with a smile: "Don't underestimate these little things, their anthills have a delicate and complex internal structure, no matter how drastically the temperature outside changes, the temperature in the anthill is unchanged, keeping it at about 30 degrees Celsius from beginning to end, and the anthill can also automatically adjust the air humidity." Of course, this is not the most important thing, the most important thing is that termites 'dig' the building materials deep underground, and in the process, they bring up samples of the soil deep underground, with which we can understand the mystery of the underground structure of the land, and perhaps explain why there are these strange creatures here. ”

After listening to Professor Wang's explanation, everyone suddenly realized that there are so many miracles in the anthill, so just take a few pieces of soil from the anthill and go back for testing.

Luo Daxi also had a good impression of Professor Wang during this time, and when he heard that he wanted soil samples, he immediately took out a sapper shovel and walked towards the termite nest.

"Daxi, what are you going to do, wait a minute." Li Hao shouted.

"What's wrong?" Luo Daxi stopped and asked Li Hao.

"Professor Wang, I just heard Meng Fan say that anthills are generally three or four meters high, and rare ones can exceed twenty meters, right?" Li Hao asked.

"That's right, such heights are really rare." Professor Wang replied.

"Then why did you build so high?" Li Hao asked again.

Meng Fan didn't wait for Professor Wang to answer, he already understood what Li Hao meant, and said to himself: "Could it be another group of monsters!" ”

Li Hao nodded with a smile and said to Luo Daxi, "Okay, you can go." ”

"Damn, rat, rat, you want me to feed the ants, you want to go to you." Luo Daxi had already heard what Li Hao meant, and understood that the reason why this termite nest was built so high was probably because the ants were as big as yesterday's spiders.

"Okay, I'll do it." Li Hao had long thought that he could only rest assured if he went by himself.

"Mouse, you're not going to come really, are you?" Luo Daxi began to regret saying such a thing, let Li Hao go to a dangerous place, then he would rather take risks himself than go to a good brother.

"It's okay, only I can go, you don't have to want to go for me, I'm sure I'll come back. Don't be idle, help me see more grass and make a torch when the time comes. ”

"Brother Li, use some of this." Xiaoxian took out a small bottle and threw it to Li Hao. Li Hao took it and saw that it was a mosquito repellent spray and said thank you.

"I don't know if it will be effective or not, ordinary mosquitoes can be useful, you can spray a little more, maybe it will be effective." Xiaoxian said.

Li Hao sprayed all over his body, and slowly walked towards the termite nest with a large torch prepared by Luo Daxi and a sapper shovel on his back, for everything about this ruin, Li Hao wanted to know more than anyone else, Professor Wang was for the purpose of scientific research, and Meng Fan was for the purpose of being competitive and shameful, so he himself had a deep hatred of blood, how could he let go of a little clue.

Now close to noon, the surface temperature of this sandy surface can reach more than 40 degrees, and many insects choose to hunt and eat at night to avoid the heat. In the dense forest, spiders are shaded by trees, and the temperature will be much lower than this bare surface, so they also come out to attack targets during the day, and termites are the same, this is the instinct of animals, so Li Hao did not see a busy figure on the way to the termite nest.

Coming to the front of the anthill, Li Hao admired these magical founders even more, the towering chimney in front of him stood in front of him like a giant, he had to admire the skill of these insects to seize the sky, with diligence with a grain of sand to pile up this behemoth.

What is it? Li Hao found a few black charcoal grains near the anthill, he bent down to pick them up and sniffed them with his nose and said, "It turned out to be them." ”

Then Li Hao threw away the charcoal particles and took off the sapper shovel from his back, and found a slightly bulging place to shovel down, hey, a shovel went down and left only a trace of marks on the anthill, and there was no Li Hao worried that the whole anthill would be shoveled.

What's going on, Li Hao was a little puzzled, the seemingly fragile anthill didn't move at all, and then look at the sapper shovel, the shovel is also sharp, even a tree can be shoveled in a few centimeters at once, and this sandy anthill is so unscathed, it is difficult to slip just now? Li Hao took the sapper shovel and shoveled it hard, and with a bang, the shovel hit the anthill with a loud noise, and it was just a little splash of skin.

What a sturdy anthill, Li Hao knew at this time that he still underestimated these seemingly weak termites, but he didn't expect that after ordinary gravel and the adhesive they secreted, this anthill was so hard, just when he had enough strength to shovel for the third time, there were already termites on the anthill showing their heads and shaking their two antennae. Seeing this termite with a section of its body exposed, it scared Li Hao a lot, is this a termite? It is the size of an ordinary house mouse, and if it is bitten by its two sharp and hard chelicera, it will lose a piece of meat if it does not die.
