"Brother Zhao, are you saying that this is a karst cave formed by a volcanic eruption?" The Manjun who followed behind Zhao Hongtao picked up a stone from the ground and said, "Maybe the volcano erupted in northern Qiongbei flowed here and became this stone mountain......

"Lao Man, this is impossible......"

Hearing the words of the Manchu army, Zhao Hongtao said with a little crying and laughing: "It doesn't matter if it's an extinct volcano or an active volcano, it will leave a crater, and the volcano can't erupt that 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 antique cultural toys, he can barely be regarded as half an expert, but when it comes to geological things, Man Jun just doesn't know anything, and all he says is the words of a layman.

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

"Brother Zhao, are volcanic caves rare?" Seeing Zhao Hongtao's excited appearance, Fang Yi said with some puzzlement: "Isn't the cave just a passage left after the volcanic eruption?

Fang Yi learned most of the knowledge of Taoism, and it was his strength to say that talisman alchemy and immortal cultivation were his strengths, but his understanding of geological knowledge was probably even worse than that of the Manchu army, so this question also made Zhao Hongtao cry and laugh.

"Who told you that the natural cave was erupted by a volcano?"

Zhao Hongtao said angrily: "The natural karst cave is caused by the change of the bottom crust, the seawater becomes land, but the groundwater contains calcium bicarbonate, and after tens of millions of years of corrosion of the rock, what does it have to do with volcanic eruptions?"

"Isn't that a volcanic cave rare?" Fang Yi understood now, but he still didn't understand the discovery of a volcanic cave. Why is Zhao Hongtao excited to look like this.

"Of course, it's rare, only two have been found in China so far, and both have not been developed......"

Zhao Hongtao's eyes emitted a glimmer of light, and he said: "If I'm not mistaken, this place should be the third, Fang ∑style_; Escape. Did you know that this discovery indicates that there was a volcanic eruption here, which is of great significance to the study of volcanoes by the relevant authorities......"

Although Zhao Hongtao is not an expert in geology, nor is he the first person to discover this cave, he is a history major, and he can be regarded as a person in the scientific research community, if he can become the first person to prove 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 place in the academic world. The higher this status, the more secure his position will be, and it will also be of great benefit to his future ascension.

Thinking that he would be the first scholar to demonstrate this volcanic cave, Zhao Hongtao couldn't help but feel hot in his heart, turned his head to look at Ah Bao, and said, "Ah Bao, can we spend the night in Miao Village?"

Publishing a paper on volcanic caves is not something that can be done in just a few hours. Zhao Hongtao needs to do a lot of work, and he even has to take different volcanic stones from inside and outside the cave and bring them back for analysis and analysis. Thus the reason for the formation of this volcanic cave is obtained.

"Brother Zhao, if you don't want to leave today, let's deal with it overnight in the car or in this cave......" Before Ah Bao could answer Zhao Hongtao's words, the Man Jun said: "Go to Miao Village to live or forget it, let's win two trees in the bet today, what if someone gives us a trick?"

Although the Manchu army did not deal with the Miao people like Ah Bao and Zhao Hongtao. But he has read a lot of martial arts novels, just like the blue phoenix written in Jin Daxia's "Smiling Proud Jianghu", which can make people die or live under the Gu worm in one hand, so Boss Man also has special scruples about Miao people.

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

For the Gu worms of the Miao people, Ah Bao was also very curious before, and he once secretly asked Ah Ming these things.

According to Ah Ming, after the death of the wizard, the inheritance of raising Gu was almost cut off, and 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, but as long as they were not offended, the family would not release Gu worms to hurt people for no reason.

"I guess I won't be able to sleep long this night, otherwise, Lao Man and Fang Yi will follow Bao to live in Miao Village......"

Just now found out that this is a volcanic cave, Zhao Hongtao only cared about the excitement, but forgot his own experience, listening to the Manjun said, he would rather be bitten by mosquitoes here than go to Miao Village to spend the night.

"Don't go, we'll be here with you......" What Zhao Hongtao didn't expect was that Man Jun and Fang Yi wanted to stay in unison.

Of course, the motives of Man Jun and Fang Yi to stay are different, Man Jun is really a little scared in his heart, while Fang Yi thinks that this cave is a place of extreme yin, in case Zhao Hongtao goes deeper, he is afraid that he will worry about his life, so he has to stay and take care of Zhao Hongtao.

"Boss Zhao, why don't we go out of the mountain first, and come in again tomorrow?" Ah Bao said next to him, there are a lot of mosquitoes in this mountain at night, and there are only two people sleeping in the car, so staying here overnight is simply a crime.

"Ah Bao, this cave is very valuable for research, let's stay, tomorrow there will be another daytime, and we will almost be able to go out of the mountain......" Zhao Hongtao naturally wouldn't tell Sù Ah Bao, he really didn't want to take another car to run this mountain road, the previous trip, Zhao Hongtao almost vomited all the bile.

"Okay, I'll call Lao Gu and tell him that we won't go to dinner at night......" Ah Bao nodded helplessly, took out the phone and said, "I'll go to Ah Ming's side and bring some food later, you guys must not go into the hole too deep, lest you get frostbitten......"

In the past, this cave did not only make children sick, some hot young people often coveted the cool inside and would go deeper, and after coming out, the whole person would shiver like a pendulum, and they would have to get seriously ill.

"Didn't you say it was a volcanic cave, it should be warm inside...... "Man Jun muttered.

"Old Man, this volcano has already erupted, if you feel warm, then aren't you sitting on the crater?" Zhao Hongtao joked with the Manchu army with a smile, and said: "Let's go, go in and have a look, our range of activities this time is within ten meters of the cave......"

As he spoke, Zhao Hongtao went into the hole, followed by Fang Yi, and the Manchu army followed up last, but the hole was spacious enough, and the difference between standing inside and outside the cave was not very big, and it could be stepped out in one step.

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

As soon as they entered the cave, Fang Yi and the others felt that the heat generated by the 356-degree high temperature outside disappeared all of a sudden, as if they had walked into a shopping mall with enough air conditioning in the city, and it suddenly became extremely cool.

"No wonder the Miao people in the past liked to come here to escape the heat......

Zhao Hongtao rubbed the goosebumps on his arm that turned from hot to cold, he now believed Ah Bao's words, this cave is indeed inhabitable, even at the entrance of the cave, I am afraid that you have to cover a quilt when you sleep at night.

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

After observing the surrounding environment, Zhao Hongtao found that at the entrance of this karst cave, it was a very wide space, with a top height of more than ten meters and a length of about forty meters, 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, and the lights are turned on, and the colors formed by various lava are very gorgeous, and the ground is relatively flat, no wonder Ah Bao and these children like to play in it before.

"It's carbide ash, and it's really a ...... formed by a volcanic eruption."

After getting used to the temperature in the cave, Zhao Hongtao began to observe around his body, the characteristics of this volcanic cave are very obvious, and there is no need for special survey, some lava related to the volcano can be seen almost everywhere. (To be continued.) )
