"Brother Zhao, are you saying that this is a cave formed by a volcanic eruption?" Man Jun, who was following Zhao Hongtao, picked up a stone from the ground and said, "Maybe the volcano erupting in Qiongbei flowed here and turned into this stone mountain..."

"Laoman, this is impossible..."

Hearing Man Jun's words, Zhao Hongtao said with some amusement and silence: "No matter whether it is an extinct volcano or an active volcano, there will be a crater left, and the volcano cannot erupt so far. Qiongbei is one or two hundred kilometers away from here..."

"Brother Zhao, I don't know much about this knowledge..."

Man Jun scratched his head and smiled bitterly. When it comes to antiques and cultural relics, he could barely be considered half an expert, but when it comes to geology, Man Jun just knew nothing and said everything was a layman's words.

"It should be a volcanic cave. Look, this stone has the characteristics of basalt, which is commonly known as volcanic stone. I really didn't expect that there would be a volcanic cave here?" Zhao Hongtao's face showed a look of excitement, which seemed even more excited than when he won the bet on a tree.

"Brother Zhao, are volcanic caves rare?" Seeing Zhao Hongtao's excited look, Fang Yi said in confusion: "Isn't the cave a passage left after the volcanic eruption? It seems that there is nothing strange about this, right?"

Fang Yi learned a lot from Taoist knowledge. He said that making talismans and alchemy to cultivate immortals and ask for Taoism was his strength, but his understanding of geological knowledge was probably worse than that of Man Jun, so the question also made Zhao Hongtao laugh and cry.

"Who told you that natural caves were volcanic eruptions?"

Zhao Hongtao said unhappily: "The natural cave is caused by the change of the bottom shell, and the seawater becomes land, but the groundwater contains calcium bicarbonate, and the corrosion of the rocks over tens of millions of years is what does it have to do with the volcanic eruption?"

"Are volcanic caves rare?" Fang Yi understood this time, but he still didn't understand why he discovered a volcanic cave. Why was Zhao Hongtao so excited?

"Of course it's rare. Only two have been discovered in China so far, and none of them have been developed yet..."

Zhao Hongtao's eyes emitted a ray of light and said, "If I read it correctly, this place should be the third one, Fang∑style_;Yi. Do you know that this discovery shows that there have been volcanic activity here, which is of great significance to the relevant departments' research on volcanoes..."

Although Zhao Hongtao is not an expert in geology, nor is he the first to discover this cave, he is from a historical major and a well-off scientific research community. If he can become the first person to argue this place as a volcanic cave, it will still cause a great sensation in the domestic scientific research community.

As an expert official, Zhao Hongtao needs a position in the academic world. The higher his position, the more stable his position will be, and it will also be of great benefit to his future rise.

Thinking that he would be the first scholar to argue about this volcanic cave, Zhao Hongtao couldn't help but feel hot. He turned to look at Abao and said, "Abao, can we spend the night in the Miao village?"

If you want to publish a paper related to a volcanic cave, it cannot be done in just a few hours of investigation. Zhao Hongtao needs to do a lot of work, and he even needs to take different volcanic stones from inside and outside the cave for testing and analysis. This will obtain the reason for the formation of this volcanic cave.

"Brother Zhao, if you don't want to leave today, let's deal with it all night in the car or in this cave..." Before Abao answered Zhao Hongtao's words, Man Jun said, "It's better to live in Miao Village. We won two trees today. What if someone is sucked?"

Although Man Jun has never dealt with Miao people like Abao and Zhao Hongtao. He has read a lot of martial arts novels, just like the Blue Phoenix written in Jin Daxia's "The Smiling and Proud Wanderer". The one-handed worm can make people die, so Boss Man is also particularly concerned about Miao people.

"It's okay to live at Aming's house. I promise he won't hurt you..." Abao said with a smile: "And it's not as evil as Brother Man said. Now there are very few Miao people who raise Gu, and there is no one in Aming's family anyway..."

Abao was also very curious about the Miao people's insects before, and he had secretly asked Amin about these things.

According to Amin, after the wizard passed away, the inheritance of raising Gu was almost cut off. There were no more than five families in the entire mountain who knew how to raise Gu. Although there was a family in Shishan Village who knew how to raise Gu, as long as they did not offend them, the family would not release the Gu insects for no reason and hurt people.

"I guess I can't sleep for a long time this night. Otherwise, Lao Man and Fang Yi, you can follow Abao to live in Miao Village..."

I just discovered that this was a volcanic cave. Zhao Hongtao was only excited, but he forgot his experience back then. After hearing what Man Jun said, he would rather be bitten by mosquitoes here than stay in Miao Village.

"If you don't go, we'll be here to accompany you..." What Zhao Hongtao didn't expect was that Man Jun and Fang Yi were trying to stay in unison.

Of course, the motives of Man Jun and Fang Yi to stay were different. Man Jun was really scared, while Fang Yi thought that this cave was an extremely dark place. If Zhao Hongtao went deeper, he would be afraid of his life, so he would stay and see Zhao Hongtao.

"Boss Zhao, why don't we go out of the mountain first and come in tomorrow?" Abao said from the side. There are many mosquitoes in the mountain at night, and there are only two people sleeping in the car. Staying here for the night is simply a disaster.

"Abao, this cave is of great research value, so we'd better stay here. There's another daytime tomorrow, and you'll be able to get out of the mountain..." Zhao Hongtao naturally wouldn't tell Abao that he really didn't want to take the bus to take another trip to this mountain road. On the trip he came before, Zhao Hongtao almost vomited all his bile.

"Okay, I'll call Lao Gu and tell him we won't go to dinner tonight..." Abao nodded helplessly, took out the phone and said, "I'll bring some food later. You guys must not go into the hole too deep, so as not to get frozen and sick..."

In the past, this cave did not just make children sick. Young people who are very hot often seek to get cooler inside will go deeper. After they come out, they will shiver like a whisper, and they will inevitably get seriously ill.

"Didn't it mean it's a volcanic cave? It should be warm inside..." Manjun muttered.

"Old Man, this volcano has erupted long ago. If you feel warm, wouldn't you sit on the crater?" Zhao Hongtao smiled and joked with Man Jun, and said, "Let's go in and take a look. Our range of activities this time is within ten meters of the cave..."

As he spoke, Zhao Hongtao drilled into the hole, and then Fang Yi was in. Man Jun followed in the end, but the hole was spacious enough. The difference between standing inside and outside the hole was not very big, and you could take it out in one step.

"Hey, there is no gate in this cave, why is it so cool after coming in?"

As soon as they entered the cave, Fang Yi and others felt that the heat generated by the 35 or 6 degrees outside disappeared in an instant, just like they walked into a shopping mall with air-conditioning in the city, and suddenly became extremely cool.

"No wonder the Miao people used to like to come here to escape the summer heat..."

Zhao Hongtao rubbed the goose bumps on his arms from the moment he turned from heat to cold. He believed that this cave was indeed impossible to live in. Even at the entrance of the cave, he would have to cover a quilt to sleep at night.

"If it weren't for the temperature, this place would be a place for people to live..."

After observing the surrounding environment, Zhao Hongtao found that at the entrance of this cave, there was a very wide area, with a top of more than ten meters high and about forty meters long, covering a total area of ​​about four or five hundred square meters.

At the top of this space, there are many strange-shaped stalactites hanging upside down, turning the lights upside down, and the colors formed by various lava are very bright, and the ground is relatively flat. No wonder children liked to play in it before.

"This is carbonized ash, it is indeed formed by a volcanic eruption..."

After adapting to the temperature in the cave, Zhao Hongtao began to observe around his body. The characteristics of this volcanic cave are very obvious and do not require special surveys. Some volcanic-related lava can be seen almost everywhere. (To be continued.)
