Soon Xuanyuan Hong took Hong Er and Hong Liu to converge, the meeting place was behind a big tree, under the dense shade of the tree, the people in charge of guarding on the opposite side couldn't find them at all, but they didn't dare to get too close, otherwise they would be easily discovered.

Although the people on the other side did not have uniform uniforms, they were very disciplined in their actions, apparently only in the regular army.

"Captain, this is a kingdom on the border of our country, the army of the Kingdom of Reihante, their commander Halt I have seen before, otherwise I really wouldn't be able to tell the difference. Hong Liu reported to Xuanyuan Hong that the difference between an empire and a kingdom is very different in terms of military strength, land area and number of strong people, and it is very simple for an empire to destroy a kingdom.

However, there is only this information, and as for what exactly they are doing, there are no clues yet, and further investigation is needed.

However, the guards inside were very strict, and Hong Liu tried three times but couldn't get in, and if he forced his way in, he would probably be noticed by them.

"Well, you guys stay vigilant, hide well, I'll go in and take a look!" Xuanyuan Hong can only go in person, the cultivation is the highest for him, and the breathing technique is also the best for him, if there is a person in the Hongfeng team who can break in, there is no doubt that this person must be Xuanyuan Hong.

After arranging his subordinates, Xuanyuan Hong rushed into the inner circle in a flash, wanting to see what he was doing under strict vigilance.

Sure enough, it is heavily guarded, and fortunately, there are only guards on the surface on the outermost periphery, but there are hidden sentries in some of them, all hidden in the bushes or behind rocks, Xuanyuan Hong must also be very cautious in order to discover and avoid these secret sentinels, and quietly approach inward.

Fortunately, the trees here are very dense, there are many bunkers such as stones, and there are too many hiding places, so it is easy to hide, but the premise is that the breathing technique is practiced skillfully and cannot reveal any breath, otherwise even if the dark whistle can't find it, it will be discovered by the life scanner.

The most hidden place is a valley, there is a huge natural depression on the slope on the left side of the valley, there are many machines moving in the depression, it looks like it is mining, Xuanyuan Hong carefully observed for a while, and then made a final judgment, they are indeed mining.

With such a tight guard, it must not be an ordinary mineral, otherwise even if the output is high, it will be more than worth the loss in the marginal battle situation.

It must be a very valuable mineral, but there are so many high-value minerals that it is impossible to determine the type without a close look.

Xuanyuan Hong took out a professional high-definition telescope and looked closely, and found that what they dug out was a gray mineral, but there was a gray-green crystal in the gray, and these gray-green crystals were collected separately, obviously their target was the gray-green crystal.

Xuanyuan Hong knows that there are at least ten kinds of minerals that conform to the form of gray-green crystals, but which one is it?

A little familiar, Xuanyuan Hong was sure that he had never seen this mineral, but he must have known the introduction of this mineral somewhere, but he couldn't remember it for a while, but he could be sure that this was a very precious mineral, but it was not clear to what extent it was precious.

If you don't know the type or the output, you can't act rashly, at least you need to know the target value of the action.

But it's impossible to get closer, the trees and rocks near the collection point have all been cleared, and there is no place to hide on the ground, if he gets close, he will definitely be discovered, and the current distance is already the limit of what he can get close.

What to do?

Xuanyuan Hong pondered, and at this moment Xuanyuan Hong saw a person walking out, carrying a metal box in his hand, and walking towards a house not far away, the metal house was obviously built temporarily, but it was all made of high-strength metal plates, which not only had very good thermal and sound insulation performance, but also was very strong, and ordinary small arms were difficult to destroy.

Seeing this, Xuanyuan Hong immediately realized that the simple house must be a warehouse, and even contained a small office space.

The area around the simple house is not bare, and although it is heavily guarded, there is at least some place to hide.

Xuanyuan Hong decided to go over and explore, get a sample to see if he could identify the species, if he still couldn't identify it, he grabbed the mining person and asked, the person in charge of mining must know what these gray-green crystals were, otherwise they didn't take corresponding measures to collect.

Xuanyuan Hong quietly came to the vicinity of the house, and it took more than five times the time to sneak in the same distance as the outside, before he sneaked in unconsciously, the house was sealed on all sides, even if there was a ventilated place, it was also a network structure, not to mention that people and insects could not enter.

There was a door that was open, but there were guards inside and out, and it was impossible to get in without alarming them.

Xuanyuan Hong had no choice but to think about it, and in the end there was only one way, digging a hole from the side of the house and sneaking into the area.

Xuanyuan Bang found a position that was hidden by the bushes, listened carefully, confirmed that there was no one in the part and reassured, and then took out the Dragon Sword and carefully cut the metal plate, the Dragon Sword was a sixth-level divine weapon, and although the metal plate was also very strong and hard, it could not be compared with the divine soldier.

Xuanyuan Hong first separated a gap, and saw that it was pitch black inside, and there was not even a sound of breathing, and indeed no one was there, so he was a little relieved, cut open the hole that could accommodate one person to enter, and then entered the metal house in a flash.

It turned out to be a lounge, but now there is no one, and there is only one bed in the lounge, which is obviously not for ordinary people.

He turned around and set the cut metal plates, and if he didn't look closely, no one would notice that the metal plates that were the walls had been cut.

Xuanyuan Hong searched around, but didn't find anything valuable, so he wanted to open the door and go out to see if there was anything else to gain.

Just as he was about to go out, there was a sudden sound of footsteps outside the door, soft but clear without a disturbing noise.

Pushing the door, what walked in was a middle-aged man, not wearing a uniform, but it seemed that his cultivation was not low, at least at the intermediate level of the Soaring Realm, but Xuanyuan Hong hid behind the door and waited for the opportunity, and as soon as the middle-aged man came in, he just closed the door, and he shot like lightning.

The middle-aged man never thought that there would be an enemy hiding behind the door, and he was defenseless when he came in, plus Xuanyuan Hong's speed was very fast, and when the middle-aged man found out that something was wrong, he had already grabbed his neck and sealed his cultivation and mobility.

In this way, even if a middle-aged person has great ability, he can't give full play to it at all, and he can only be slaughtered by others.

Xuanyuan Hong did not interrogate, but directly went to the punishment, penetrating three forces into the meridians of the middle-aged man, creating great pain.

Although the middle-aged man has lost his ability to move, he is still writhing on the ground under the great pain, of course, it is not that he has regained his mobility, but under the stimulation of great pain, the muscles have spasms, which is involuntary muscle movements.

For three minutes, Xuanyuan Hong only waited for three minutes, and a pool of sweat appeared under the middle-aged man's body to the ground.

The huge pain made the middle-aged man's face pale, and his body was weak and exhausted.

"I need to ask some questions, answer me truthfully, don't play tricks, or you'll experience something more 'wonderful' than you just did. After Xuanyuan Hong finished speaking, he unlocked the middle-aged man's ability to speak, and his cultivation was still sealed, and even his ability to act was not released.

The middle-aged man really didn't shout, but looked at Xuanyuan Hong, who was squatting beside him, with eyes full of fear.

"Let me ask you, what is the purpose of your gathering here?" Xuanyuan Hong asked, he had observed just now, everyone counted, there were at least three thousand people gathered here, and all of them were the elite of the elite, and none of them were weak.

"Mining. ”

"What mine?"

"Super energy rare earths. ”

"Super Energy Rare Earth?" Xuanyuan Hong was taken aback, he knew that Super Energy Rare Earth was a very rare high-grade mine, even if it was an ordinary Super Energy Rare Earth, the value was very high, and the veins of Super Energy Rare Earth were generally not very large, and it would be easy to be mined clean.

Super rare earths are some precision materials necessary for them, and they are irreplaceable so far, so the value has been rising, but the amount mined is limited, which is also the reason why the price of super rare earths continues to rise, and the number of discoveries is very limited.

What is gray is super rare earth, and what is gray-green crystal?

Ultra-rare green crystal, a member of the super rare earth family, is the most advanced, the purest and the least common.

It can be said that under the same grade, the value of ultra-rare green crystal is not less than that of high magnetic black iron, and even about one-third more expensive, even if it is an ordinary super rare earth, it is also a very sought-after material.

It's no wonder that so many people will be filmed to defend layer by layer, it turns out that there is an ultra-thin green crystal, even if there are more people, it is worth it.

If it is Xuanyuan Hong, he will also get the ultra-rare green crystal at any cost, after all, the quality of the ultra-rare green crystal is too high and rare.

"How many of you are here?" Xuanyuan Hong continued to interrogate, since he had decided to take down this batch of ultra-rare green crystals, he had to know the bottom line.

"Four thousand two hundred. ”

"To what extent is the strongest cultivation, is he also here?" this is what Xuanyuan Hong is most concerned about, he believes that it is impossible to send only some ordinary people to guard such precious mineral deposits as ultra-rare green crystal, there must be some strong people in charge, and only the most powerful and powerful guarantees.

Only by figuring out how many super strong people are in charge and what the specific distribution is, can he decide how to seize the super thin green crystal that has been mined, such a huge piece of fat, Xuanyuan Hong is reluctant to miss it, and the only hope is that the strong people in the town are not too strong.
