It wasn't until the next day, after Su Liucherou had tested that the concentration of poisoning gas in the air in the valley would not affect the human body, that everyone re-entered the valley.

The snow-white valley has changed beyond recognition, and the valley is scorched black everywhere, and there are insect corpses everywhere. These silk worms are green and scary-looking. Even these experienced Kasiu people couldn't help but change their faces slightly when they saw this scene in front of them.

However, they moved very quickly, and they knew that this would be their fortress for a long time.

The violent explosion changed the terrain in the valley, and the soil and snow were blasted open, revealing the purple rocks below.

"Purple Radiant Mine! It's the Purple Glowing Mine! I said that the concentration of metal compounds in the air here would be so high. Brenton bent down and touched the purple rock formations, and suddenly became agitated.

"Brenton, what is the Purple Glowing Mine?" Xi Ping narrowed his eyes and asked curiously. During the time he was in contact with Brenton, Xi Ping already had a certain degree of understanding of the blonde teenager. Brenton is very young and immature, but his theoretical knowledge is quite rich, or it can be solid.

"Purple fluorescent mineral is a complex metal compound, it cannot be used directly, but it contains many rare metal components. It is a pity that the decomposition and purification technology of Ziying Mine has always been a very high-end technology, which is only available in the hands of some large groups. Brenton had a look of regret on his face, but he quickly perked up: "If we sell this news to a large group, we will definitely make a good profit." ”

Bagnell glanced at Brenton like a fool: "How can we give such a good thing to others?" ”

"Scrooge." Brenton had no fear of Bagnell, his face flushed, and he said loudly, "Without this technology, it is useless to guard the Purple Glowing Mine." Purple glow mines that have not decomposed are of no use. ”

"It's a potential stock, you know?" Bagnell snorted.

"Uncle, you can dream of making a fortune." Brenton sneered disdainfully.

Xi Ping smiled and watched the two arguing, and he didn't mix. And Chen Dui on the side was moved. He hadn't heard of Ziying Mine before, and he didn't know what it did. But listening to Brenton in this way seems quite valuable.

However, the decomposition technique that Brenton mentioned is not too much of a problem for Chen. He had been with Alfonso for so long, and although he hadn't learned all the metal crafts of the Wan Qi clan, it was difficult for him to use techniques like purification.

Soon, the valley was cleaned up, and it was Brna's turn.

Brna held the latest construction card repair machine that Xi Ping bought for him, and it only took half an hour to complete the scanning of the valley terrain.

From the light curtain that pops up from the jam, you can see a complete three-dimensional view of the entire valley.

Brna's design took three full days, a process that he discussed back and forth with Bagnell. The communication and tacit understanding between the two is not a problem at all, which makes the work progress speed up a lot.

In the past three days, Chen Du did not let these Kaxiu idle.

All the Kaxiu exercises their perception in the snow, which is Chen Dui's order. Although many people shivered from the cold, they glanced at the boss who was taking the lead in training, and they were all honest.

It wasn't a spur of the moment for Chen Du to let these Kaxiu exercise their senses in the snow. Since entering the ice and snow area, he has clearly felt that exercising in such a cold place has indeed achieved twice the result with half the effort. It was only then that he realized that Brenton's previous statement that Cassius liked to go into ice and snow was indeed undoubted.

Ever since discovering this feature, Chen has been figuring out how to take advantage of it. He's very happy with the Kasiu he has in his hands and they've proven that they're a good player these days.

However, Chen Du also saw their limitations. The perception of these Kaxiu is too weak, and some of them are still at the level of level three, and the others are only level four. The lack of perception is the weakness of these Kaxiu.

If their perception is higher, Chen Du will be able to design stronger sets.

What's more, these Kasiu are very young. The oldest is only twenty-five or sixteen years old, and the younger one is even only ten years old. If they were allowed to develop like this, Chen Du felt that it would be a pity.

After carefully studying the perceptual exercises they had learned, Chen Duan had a new idea.

Most of what these Kaxiu learned were some basic perceptual exercises, except for a few, such as Jiang Liang, who knew how to use the military's perceptual exercises.

This is a method called the B-standard perceptual exercise. Jiang Liang did not hide anything from Chen Dui, and explained this exercise method carefully and carefully.

After researching, Chen Duan found that the biggest feature of this military perception exercise method is that it is simplified and reasonable. It allows people to learn all kinds of qualities at the same time, and although it can't be compared to the advanced exercises of the Big Six, it is still an excellent method.

It and the extreme exercise method that Chen Du is practicing now are two complete extremes. It's gentle and harmless, while extreme workouts are violent and extreme.

These days, Chen has been trying to simplify the extreme workout. As his knowledge grew, he also knew that the extreme exercise method was not something that everyone could practice. It's an excellent method, but it's also an extremely dangerous one.

Jiang Liang's B-standard perceptual exercise method gave Chen Du considerable inspiration. With this reasonable perceptual exercise method, Chen Duan can even find a little bit of the principle of perceptual exercise from it.

After more than 20 days of hard thinking and meditation, he finally got a simplified version of the extreme exercise method. Although the simplified method is not as amazing as the effect of the real extreme exercise method, the danger is not so big, and the theoretical effect can also make him more satisfied.

However, looking at the Cassius who insisted on practicing perception on the snow, Chen Du hesitated. The simplified method that I figured out by myself has not gone through any practice, and it is unknown whether it is effective or not, and whether there are side effects. And this kind of attempt surname is a certain dangerous surname.

A perceived injury, unlike a physical injury, is more difficult to heal and more difficult to recover.

After thinking about it, Chen Duan walked in front of Jiang Liang.

Jiang Liang was almost the most ascetic of all the Kaxiu, and since he knew that exercising his perception in the snow would help him grow, he simply sat shirtless in the wind and snow to practice. Every time I finished practicing, my face was so cold that I was blue, and I had many frostbites all over my body.

This also caused Su Liu Cherou to have a lot of opinions about Chen Dui, and by now, several Kaxiu had suffered from frostbite. However, because it was Chen Duan's order, no one flinched.

"Boss." Finding Chen Du in front of him, Jiang Liang immediately got up and saluted expressionlessly.

Looking at this resolute face, Chen Dui's gaze fell on Jiang Liang's shirtless upper body, his sturdy body was already covered with chilblains, and suddenly, he had a trace of realization in his heart.

"I just designed a set of perceptual exercise methods, and there is no validation, would you like to try it?" Chen Duan looked at Jiang Liang with a calm expression.

Jiang Liang's indifferent eyes suddenly became hot, his face that was frozen and pale was flushed, and there was a trace of trilling in his voice, but he replied firmly: "Yes!" ”

Bagnel looked at Brna, who was doing magic, while chatting with Xi Ping.

Brna was like a magician, and the valley had changed its appearance at this time, and some rudiments could already be seen. The construction carshuts float over the valley in a snail-shaped shuttle. These shuttles have many nozzles that eject a warm liquid that, when it comes into contact with the air, quickly solidifies and becomes extremely hard.

All of the buildings were made up of walls of ice solidified by these warm liquids, and Bagnel tested their hardness, and the weaker energy bodies hit them, which were of no use except for the flying of ice chips. And the most interesting thing is that these ice walls are extremely easy to repair, as long as you pour those warm liquids into them, they will be as good as new.

Bagnell smacked his mouth: "When did Brner have this technology?" I've never seen him use it before. ”

"Oh, last time I brought a magic card of the construction method of Tiandongli District, I guess he is now learning and selling." Xi Ping said slowly, at his feet, Xiao Yangbo's little nose was red from the cold, but his curious little eyes widened, and he felt that everything in front of him was amazing.

Rubbing his hands, Bagnell complained with heat: "Hey, this guy is so slow, I don't know what year and month I want to live in." After speaking, he suddenly glanced at Brenton, who was chatting happily with Ru Qiu: "What about the blonde boy?" ”

Xi Ping groaned: "Ask the boss." By the way, what has the boss been doing in the past two days? Chen Dui's strange situation in the past two days fell in Xi Ping's eyes, and he was a little worried.

Bagnel shrugged: "Who knows, Jiang Liang, that guy is mysterious with the boss every day." Hehe, every day bare-chested, I look at Miss Su Liu's eyes with a bit of murderous energy. After speaking, he touched his chin and said thoughtfully: "Could it be that the boss's taste is more special?" ”

Jiang Liang was shirtless, and in front of him, there was a snow pit. The pit was a man deep, and it was filled with snow.

He took a deep breath and jumped into the pit without hesitation, then lay flat in the snow.

Seeing that it was lying down, Chen Dui quickly pushed the snow next to the snow pit into the snow pit, and in a moment, the snow pit was really flattened.

After doing all this, Chen Duan sat by the snow pit and closed his eyes.
