After coming in, the heat outside suddenly became cold, and I was still worried about how to prevent heatstroke and cool down just now, but now I am immediately much more comfortable. The air circulation inside is not bad, which makes Xiao An feel very magical, I don't know if there are people living in it, or it is a masterpiece of nature.

Xiao An checked the surroundings and found that it was very clean, without as many scary bugs as expected. Therefore, it is more certain that this place is definitely inhabited, at least occupied by animals with high intelligence, otherwise everything cannot be planned to look decent. Alas, since people are so good here, it is even more necessary to pay attention to it, so as not to destroy other people's homes. Everyone is here for adventure and curiosity, not for a demonstration and a declaration of war, and in that case, it would be contrary to the original intention.

So, the professor asked the guide to shout into the cave as much as possible in the local language, if there is any, ask them to come out.

However, the guide shouted several times, but there was still no response.

Why, is this a group lunch break, or are we all in a meeting? If we don't have the owner's permission, we won't dare to trespass!

Now that we know that this place is inhabited, if we are not more humble, will we not find trouble? What's more, in addition to the problem of politeness, I am also worried that I will be set a trap, which will outweigh the losses.

So, the guide repeatedly emphasized to the people who might exist inside: We have no ill intentions, and we have also brought gifts, so we are here to rest and cool off, and if no one agrees, we can take it as an agreement to go in directly.

Still no one agreed.

"Well, since we've already informed the inside, they didn't respond, so it's not our trespassing. What's more, we didn't come in to do any damage, we just liked the coolness of his place, so let's take a good rest first! Everyone is tired anyway! ”

The professor beckoned everyone to come in and find a clean place to rest, and a large group of people officially entered the cave that had never been entered.

I don't know if I don't come, but when I come in, I find that this place is many times more beautiful than I imagined. Xiao An thought of the Weiss Church in Germany, and also thought of the underground buildings dug by someone abroad, all of which have beautiful ceilings and murals, and this place is no exception, which shows that this place that is difficult for the outside world to enter and few people know about is still hiding so many skilled craftsmen.

Since they have such beautiful buildings, will they also have their own unique education system? Otherwise, how would these murals have been made?

Everyone rested for a while, and gradually recovered, and the leader urged everyone: "Okay, have you rested enough?" We've got to move on! Don't forget our mission, it's not just here for a vacation! ”

After listening to his words, the group continued to move on, but they never saw their master.

It's possible that there are no people ruled here for a long time, or they have been wiped out, or they have been moved to another place in time after they were discovered, and in short, after everyone has been in for so long, there has not been a single figure, let alone the long-awaited blue-and-white Lacanton.

"Professor, did you say that in a nearly confined space, the temperature and humidity are relatively constant, and no one will clean it for a long time, but as long as no one destroys it, there will be almost no dust?"

Someone asked.

"This-" It seems that the professor is not an expert in physics.

"I'll answer that question!" One person rushed to reply, "I think it is very difficult to achieve the situation you said no matter where it is, as long as it is on the earth, unless it is used for scientific experiments." Perhaps, it will be possible to have a vacuum state, where dust and the like are pumped away before the vacuum is injected. But in this case, there should be no air, and if there is no air, there will be no circulation, and how can people breathe? You're wondering why there's no one here, but it's always clean, right? I think there should still be people here, and it can't be because I haven't been here for a long time, so it's so clean. ”

When Xiao An heard this, he looked down at the floor under his feet, only to find that it was a natural dirt road before, but now it was already a paved floor.

"Oh, no, why does the floor here look so stolen?"

A boy shouted, Xiao An glanced at him, and made a fuss, this place has almost no contact with the outside world, how could it be stolen.

"Stole? What do you mean by stealing? "Someone is interested.

"This is the latest flooring, my family is in the interior design industry, and I am naturally very sensitive to this. This is obviously a flooring manufacturer that has not yet had time to go on the market in a large area! How did it end up here? ”

"Maybe it's just a coincidence, but no book can be made without coincidence! Moreover, there are some ideas that we only have there, but they can't appear elsewhere? It is also possible that the flooring manufacturer got the idea here, thinking that no one knows anyway, so it is better to use it on the product and make a profit! Someone explained it this way.

Will it? It's far-fetched. Although, in the current conditions, this statement seems to be true. Well, I can't care so much now, just follow along, who knows what else will be fun ahead?

It's really different from Barmond's cellar, there is only an endless supply of tequila, nothing else, dark, damp and monotonous. Although this place is a cave, it may not have reached the real underground yet, so after passing through a slightly narrow hole, everyone walked about 500 meters, and there were steps in front of them, which were downward.

Sure enough, it's an underground tunnel!

Everyone was overjoyed to see this.

"It's great, I can actually see this place in my life, even if I die, I have no regrets!" The professor seemed very excited, "Hurry up, you guys, take pictures of all this with your camera!" Then let a few people evacuate to a place where there is a signal to spread, and send it to the school computer now! He instructed a few students in this way, and after they received the order, they immediately began to take pictures, and after taking pictures, they sent people to run out of the cave again, looking for a place to send mobile phone pictures.

How many photos can be taken, how many photos can be sent, and you can't be too greedy. Otherwise, if it is discovered by the owner and objected, let alone the present, it is the good scenery that will be encountered later, and it may have to be ruthlessly deleted.

From this point of view, the professor should be a pure scholar, quite benevolent, unlike those who use this as a cloak but are actually touching the gold captain.

Xiao An felt that although he might not get rich with such a person, he should at least be safer, and if he really met the owner of the tunnel, he would not have any conflict with them. Besides, money is secondary, and this time I came mainly to accompany Marta to explore and study together, as for the rest, I didn't think much about it. As long as she can get out of here safely with everyone and return to the surface, this is her greatest wish at the moment.
