"Stone spirit, stone core, produced from the cave heaven?" Du Qian exclaimed, no wonder there are so many talisman masters in the team.

Master Jufu is very rich, but it is too difficult to buy these two things. Even if you encounter them occasionally at auctions, with their financial resources, you will definitely not be able to compete with those old master Jufu.

"That's right, you can't find these two materials except cave heaven." Qian Wuming nodded and said, Qian Wuming really doesn't care about money or something, but these two materials are too important to him.

Buy it? Forget it. There may be several copies on the three major shots every year, but there are too many people watching, so I will definitely not be able to buy them.

In fact, which adventure team that can get the Cave Heaven Exploration Token has no energy behind it? The stone essence and stone core they found was directly in the hands of the higher-level talisman gathering master, and few of them leaked out to the auction hall.

"How many caves do our empire have?" Du Qian asked hurriedly.

"There is only one in the territory, no wonder, not only is there one in Zhoushan, but there is only one in Zhenhai and Butian. Do you think, how did the three major forces form? Without Cave Heaven, it is impossible to become a super force." Qian Wuming said with a smile on his lips.

The history of human war is actually a history of fighting for survival space and seizing development resources. There is no benefit. Who is willing to start a war?

History books? What a mess? Whoever is in power will modify and modify it. Write it according to your needs. Are you afraid that you will not be able to find a so-called historian who is willing to flatter you?

The core values ​​are always in the hands of those in power.

"There is only one in the territory, that is, there are still outside the territory?" Du Qian's reaction was very fast, and he instantly thought of the war that would occur every one or two hundred years.

"Well, you thought of it. The biggest cave is in the buffer zone of the side mirror of the three major forces." Qian Wuming said softly.

"War is to fight for the biggest cave world?" Du Qian's face turned red. As for? These bastards all have dog brains? No matter how valuable the resources in the cave world are, they should not be snatched by war. This is not an ordinary war.

You should know that every hundred years or so, the three-party war almost brings all the forces on the entire planet together. It is not an exaggeration to say that it is a world war. The number of people who die in each war is an astronomical number.

Not to mention, for such a war, the various materials used can no longer be measured by gold coins. No matter how valuable the materials in the cave are, it is not worth solving the problem with such wars. This is simply picking up sesame seeds and throwing watermelons.

Du Qian didn't believe that the leaders of the three major forces were all idiots and would make such decisions. Moreover, such wars will last for thousands of years. Can the leaders of every regiment be too unwitting?

There must be something that I don't know about here.

"Of course not..." Qian Wuming said with a wry smile.

"Maybe there is a small part of the reason, and it is a very small part. As for the real cause of the war, it is impossible to fully understand it in my status, and at most only a small part is known."

"Can you say it?" Du Qian asked. A small part of it was already very good. At least in a short period of time, he would never know anything. Unless he asked the cheap teacher, he should know a lot in his identity.

"The reason for fighting for the share of the cave heaven is only a small part of the reason. In addition, there seems to be a plan for survival of the fittest. I don't know what it is. Of course, it may be more of a swallow." Qian Wuming said uncertainly.

"Swallow?" Du Qian frowned and repeated, feeling that he seemed to have thought of something.

"Well, the devouring theory has existed for a long time. If you want to know, you can search in the library by yourself. The content about the devouring theory is usually more obscure. Look more and think more, it is not difficult to understand." Qian Wuming nodded and said.

"Okay, I will study it." Du Qian shook his head. He seemed to feel something just now, but in a blink of an eye, he disappeared and didn't understand anything.

"Tell me about the Cave Heaven." Du Qian said.

"No need to say, you're going to the place soon. You'd better experience it yourself. The cave is magical and it's hard to express it in words."

"So fast?" Du Qian looked around in surprise. It didn't seem to take long to get here from the meeting point outside the gate of Shangjing. Even if the kinetic energy car was very fast, it couldn't run much. After all, this is a car, not an aircraft.

"Well, look there, Bu Lao Peak, the entrance to the cave heaven, is halfway up the mountain."

"Oh..." Du Qian's mind was quickly turned and he understood a little.

The Zhoushan Empire is named after the Zhoushan Mountains, and the Bulao Peak is also a symbol of Zhoushan and is the first landmark of the empire. As long as the Zhoushan Empire is mentioned, the first thing anyone thinks of is Bulao Peak.

There are countless legends about Bu Lao Peak, but unfortunately it is not open to the public. Most of the imperial civilians may not have the chance to see Bu Lao Peak in their lives. They can only see this not-magnificent mountain from reliefs on gold coins, various books and paintings.

Even if you have only handled copper coins, you will not be unfamiliar with Bu Lao Peak. But only the civilians in Shangjing can see Bu Lao Peak with their own eyes. Even if you are in Shangjing, you can only take a look at it from a distance. There is no possibility of getting close to you.

"Shangjing Bu Lao Peak, the sea capital Mu Guanglin, the Dragon Tooth Star Valley..." Du Qian murmured in a low voice.

"Yes." Qian Wuming nodded affirmatively, confirming Du Qian's conjecture.

Du Qian smiled bitterly: "I always thought that Bulaofeng specializes in producing coffee."

"Haha..." Qian Wuming laughed twice and said nothing. There are indeed many coffee trees on the Bu Lao Peak, but is that thing really delicious?

The 30-mile official road outside the Bu Lao Peak, a level established by a reinforcement battalion, appeared in front of you, hundreds of kinetic energy vehicles parked in front of the level for inspection.

Every ten miles, there is a level that is checked very closely. The first is the exploration token, followed by identity verification. Each token, the number of people allowed in the team is fixed.

Du Qian peeked and found that Zhu Ke's token level should be of high quality, and fifty people were allowed to pass. According to the habit of the adventure team, it was enough for eight members to pass through the full amount.

When exploring deep into the cave, it is not romantic at all, and it is full of crises everywhere. Every team member usually brings five attendants. Like Du Qian, who only brings one attendant, Yao Jing, can't find a second one in this long queue.

The kinetic vehicles were parked in the huge parking lot one by one. Du Qian got off the car and moved his limbs and carried his huge backpack.

"What a big parking lot." Du Qian sighed. This was the largest parking lot he had ever seen. Standing at his location, he could not see the other side of the parking lot at first sight.

"Five kilometers long, built on the mountain, using a stepped style. From a distance, it looks like a huge terrace, which can park 100,000 large kinetic vehicles at the same time." Qian Wuming also sighed. Although it was not the first time he came here, every time he saw it, he was shocked.

"Let's go, you'll know why you need such a large parking lot."

Leaving the parking lot and following the mountain road, all the adventure teams lined up in a double queue and slowly walked towards the hillside.

Half an hour later, Du Qian stood on a huge platform and waited. It would take some procedures to enter the cave, and it would not take too long.

The huge platform looked very impactful, but at this time Du Qian's eyes were attracted by the path up the mountain. For more than ten minutes, he did not blink his eyelids.

"Did you understand?" Qian Wuming asked softly. When he first came here, his expression was even more exaggerated than Du Qian.

There are no fools who have the opportunity to walk to this platform. Although you can't see the entrance to the cave from here, you can only see the mountaineering path in front of you, but it is enough to let them understand what this means.

"It's always like this up and down?" Du Qian pointed to the endless mountaineering trail.

"That's right, humans are so 'smart' and always want to maximize their interests. The entrance to the cave has reached its limit and cannot continue to expand. They can only use this stupid method, which is open all the time. This is why you need to apply in advance. Even if you have a token, you cannot enter here at any time."

On the mountaineering trail, the middle is separated by iron railings, the lower left and the upper right. During these ten minutes, the density of the abortion has not changed.

The entrance to the cave should not be big, but the internal space is extremely vast. In order to develop the resources as much as possible, more people must be sent into it.

"How many people will it take to this day?" Du Qian originally thought that only a small number of people could enter the cave heaven. Now he realized that the empire had almost used the utilization rate of the cave heaven to the limit.

"It's probably a little faster for one person in two seconds. On average, 50,000 people pass through the cave heaven a day. The exploration time is a short week and three months. A very small number of people can reach half a year. On average, it's about one month."

"One.5 million people?" In an instant, Du Qian calculated the maximum number of people exploring in the cave.

"Three million and five million." Qian Wuming shook his head and said.

"How could it be?" Du Qianyi looked surprised. How could it be? My buddy was once a top student.

"There are two million permanent populations in it, of which one million.5 million are garrisons, half a million researchers, you said one million.5 million people, an additional adventure team."

"Oh..." Du Qian nodded. He was indeed wrong. The empire's utilization rate of cave heaven was even more thorough than he imagined.

"Are you all ready? Let's go." Zhu Ke waved his hand, he had completed the final procedures.

"It's been a long time ago." Zhuoya said with a smile. The time was very accurate this time, and they didn't let them wait for long. If an accident occurs, it's nothing even if they wait on the platform for a few days.

Everyone lined up and followed the crowd and slowly walked towards the mountaineering path.

The mountaineering trail is not very long, with two bends, with a total length of less than 500 meters. After turning the last bend, Du Qian looked up and could already see the entrance to the cave.
