"Please, Brother Hu, keep please. Xiong Yan tried hard to control his feelings, and said with a smile.

"Come, Brother Hu, let's move on. Hu Feng also tried his best to control his complexion and not let himself look too stunned.

Under the leadership of the two, Populus euphratica went all the way to the innermost part of the mining area. It's already tens of thousands of meters underground. The entire underground has been almost hollowed out, and it extends in all directions, as if it were a dungeon. Countless miners are struggling to dig for black crystal.

Like operating warships and mechas, all mining machinery also requires yuan energy to drive. Without Yuan Energy, they are scrap metal. Therefore, all miners are cultivators, and they are still cultivators with relatively sufficient Yuan Energy.

There is no doubt that it takes a lot of energy to drive various machinery to excavate black crystal. Because, black crystal itself is a titanium niobium alloy, which is very strong. It's not easy to dig it out. Pure machinery is very difficult to do, and it is necessary to use the Yuan Energy Blade.

The so-called Yuan Energy Blade is to use Yuan Energy to condense into a sharp blade and directly excavate the black crystal. Well, to be exact, rip it out. It is from the large pieces of black crystal, and strive to pull out small pieces of black crystall. This process is definitely not simple, and it is very important to study the skills of cultivators.

Because of the special properties of black crystal, almost all of them grow in large chunks, and they are often veins that stretch for hundreds of kilometers, with no interruptions in the middle and no cracks. It is simply impossible to remove the whole piece of black crystal. It must be cut out in small pieces before it can be used as ore.

The reason why pine black quartz is called pine black quartz is entirely because of its special texture. The surface of each excavated black crystal has a special texture, just like the bark of a thousand-year-old pine tree. It is said that these special patterns, which are also part of the totem, have special powers. However, what exactly is the totem, no one can say clearly.

Because of the influence of these special textures, pine black quartz can only take the most primitive manual excavation methods, and all kinds of mining machinery can only be used as auxiliary. Miners must condense their own energy into a sharp blade and insert it along a special pattern to excavate the loose black crystal.

Obviously, the strength and durability of the Yuan Energy Blade condensed by the miners had a huge impact on the extraction of black crystal. The sharper the blade, the stronger the cutting power, and the longer it lasts, the larger and heavier the black crystal that can be excavated. On the contrary, of course, the smaller the lighter.

Ordinary miners of the fifteenth level of the Star Soul will take out the black crystal every time, which is the size of a fist. If it is a miner of the eighteenth level of the Star Soul, the black crystal that is extracted every time is estimated to be the size of an ordinary person's head. If it is a heavenly master, it is about the size of a grinding disc.

Somewhere in the mine, there are several huge black crystals, which were cut out by Xiong Yan, Hu Feng and others as an exhibition. The results of both of them are cubes the size of grinding discs, with a side length of about one meter, and the weight is about 100 tons. Don't look at the size of black crystal, but the density is very large, the size of the grinding disc black crystal, the volume is about one cubic meter, the weight is more than 100 tons.

"Come, Brother Hu, show your hands?" said Ha Chiyou with constant encouragement.

"Brother Hu, come on!" Xiong Yan also said eagerly, "We are optimistic about you!"

Hu Yang said casually: "It's no problem to show your hands. However, the black crystal I cut out is my own. ”

Xiong Yan said without thinking: "No problem, you can rip as much as you want, it's all yours!"

Hu Feng said with a smile: "You'd better move the entire ore vein." ”

Hu Yang nodded thoughtfully.

Suddenly, he grabbed it with both hands and inserted it into the black crystal.

Xiong Yan and Hu Feng were secretly relieved when they saw the distance between his hands. It seems that this poplar is not much stronger.

Due to the very high density of black crystal, it is difficult for the element energy to penetrate into it, and it is very important for miners to choose the location where to insert it. If your hands are too far apart, you may not be able to pull out the black crystal. If the hands are too close to each other, the volume of black crystal is too small. The position where Hu Yang's hands are inserted is a little small.

After poplar's hands were inserted into the black crystal, he didn't move for a long time, as if there was no way to penetrate the Yuan Energy. The surrounding pine black crystal did not change at all, and obviously did not feel any yuan energy fluctuations.

Xiong Yan said comfortingly: "Brother Hu, don't worry, it is estimated that you are not very familiar with the characteristics of black crystall, so you will not know where to start." Take your time, don't be in a hurry, and get to know the characteristics of pine black crystal. ”

Hu Fengpi said with a smile: "Yes, Brother Hu, you must not have been exposed to these black crystals before, and you don't know how powerful they are." Let me tell you, its characteristics are capable of highly intercepting the elemental energy. No matter how strong your Yuan Energy is, it is very difficult to penetrate into the black crystal. I'm not afraid to tell you, it's hard for my tiger's Yuan Energy to penetrate out. ”

Ha You nodded again and again, and added, "Yes, yes, most cultivators who come into contact with black crystals for the first time will most likely fail. Brother Hu, it's still the same sentence, don't be in a hurry, take your time. ”

Hu Yang said quietly: "I see. However, strangely, my Yuan Energy penetrates, and it seems that I have not encountered any obstacles. I felt as if I had penetrated the Yuan Energy five hundred meters away. If there is no accident, I can rip out a black crystal with a cube of 500 meters on the side......"

Xiong Yan shook his head and said categorically: "This is impossible. Brother Hu, this is absolutely impossible. A cube with a side length of 500 meters, what a huge black crystal must it be? Hundreds of millions of cubic meters, it is simply impossible. Even if Sister Meng Qingqing makes a move, I'm afraid it will be difficult to do it. You must be delusional. Actually, your Yuan Energy didn't penetrate out at all. ”

Hu Feng nodded and said approvingly: "That's right, you must feel that you are on a business trip." A cube with a side length of 500 meters is absolutely impossible. Even if it was the peak martial venerable in person, he didn't have that much ability. ”

Ha Chiyou's eyes flashed, and he said meaningfully to Hu Yang: "Brother Hu, do you know how much the black crystal of the cube with a side length of 500 meters weighs? It definitely exceeds 10 billion tons! The current market price of black crystal is 500 star coins per ton, and 10 billion tons is 5 trillion star coins! You can earn 5 trillion star coins with one shot? How is it possible?"

Hu Yang nodded thoughtfully, and said slowly: "Oh, I forgot about it, I can't pick up 10 billion tons of black crystal for the time being." Otherwise, I'll shrink a little and get a cube black crystal with a side length of five meters. I wonder how much it weighs?"

Ha Qiyou frowned and said, "That's tens of thousands of tons." ”

Hu Yang said lightly: "Well, just this weight is what I can bear." ”

After saying that, he suddenly burst out of Yuan Energy, and slowly dragged a huge black crystal out of the ore vein, and beads of sweat faintly appeared on his forehead, and the lines of the pine black crystal also burst out with dazzling light.

"Damn!

"God, the light of the lines is so dazzling!"

Xiong Yan and Hu Feng, as well as Bei Long, Ha Chiyou and others, were all stunned.

The light of the pine black crystal is so dazzling, indicating that the Yuan energy infused into it is extremely terrifying. The stronger the Yuan Energy, the more dazzling the light becomes. They have been digging pine black crystal for so many years, and they have never seen such a dazzling light.

Theoretically, this is simply impossible. Even the Yuan Energy of the Peak Martial Venerable is not so terrifying? How did Hu Yang do it? What kind of freak is this guy? What kind of martial arts has he cultivated?

Of course, Hu Yang would not tell them, his cultivation was up to the twenty-layer Vientiane Dumu Treasure Book, as well as the Tiger Evil Forbidden Skill and the Nine Yin Dragon Killing as high as the twenty-layer, which had an extremely terrifying effect on the strengthening of Yuan Energy. Just one of them can greatly enhance the Yuan Energy, and when several kinds are mixed together, the power has a tendency to be uncontrollable.

The pine black crystal did not react at all just now, not because the Yuan energy of Populus euphratica was not enough, on the contrary, it was because the Yuan energy was too strong, and it had exceeded the range that the pine black crystal could sense. It is too much, and it is also impossible to dig pine black crystal. After Populus euphratica reduced the strength of the elemental energy, the pine-grained black crystal was sensitive.

The density of black crystal is indeed very large, and the gravitational pull of Goro Star is much greater than that of the Earth, which is why its weight is so terrifying, weighing more than a hundred tons per cubic meter. The volume of black crystal extracted from Populus euphratica is about more than 100 cubic meters, and the weight is more than 10,000 tons. Even if he is now, the star soul level has evolved to the fourteenth level, and all kinds of martial arts techniques have been raised to the twentieth level, it is not easy to rip it out at once.

However, these are not the most important things. On top of that, the black crystal itself has a very evil property, which is that it can interfere with the cultivator's Yuan Energy. The larger the black crystal extracted, the stronger the interference ability. The black crystal extracted by Populus euphratica is really a bit big, and its ability to interfere with Yuan Energy is very strong, so that Ha Chiyou can't bear it a little bit, so he has to stay away from Populus euphratica.

Xiong Yan and Tiger Peak didn't have much of a problem, and they were able to withstand the interference of black crystal. However, with the continuous fragmentation of black crystal, it is constantly separated from the ore vein, and its interference ability is getting stronger and stronger. In the end, the two of them, who were the twenty-fourth level of the Star Soul, had to quietly retreat.
