Glimpsing Bai Qi and Lao Zhang attracted by those small points of light, Ye Qipu said, "Those are all raw ores such as crystals and gemstones, the deeper they are, the more they are, and some gems have very high hardness, which is a major obstacle to drilling in this life, which is one of the reasons why ultra-deep exploration was not possible before." Do you want to stop and dig a few pieces to send back to your wife? "The hottest Ye Qi didn't forget to make a joke.

Bai Qi said disdainfully, "Dig up these broken stones that haven't been processed yet? Now I don't just go into the jewelry stores and even the bank vaults...... Finding some gems is not trivial. ”

After a few idle words, Ye Qi continued, "Now we have broken history and broken through 18 kilometers. If it's pre-apocalyptic, what a thing to celebrate. ”

Soon, due to the width of the crack in the ground becoming too narrow, and for fear of hitting the propeller, the Gecko switched to climbing mode, and because of the unique gravity vertical system, several people in the cabin did not feel any change.

The gecko climbs very sensitively, especially when Ye Qi uses his own brain waves to control it, it is more fluent.

"It's already 20 kilometers, and the temperature outside is close to 1,000 degrees." Ye Qi said about the situation outside.

At this time, the situation outside has also changed a little, no longer endless darkness, but there is a faint ghostly light, I don't know what the light source is, but it is certain that there is definitely a bright light.

"Damn! There are less than 300 meters to go. Ye Qi stared at the data displayed on the screen and said.

It's very demoralizing, and the depth is not as deep as forty is said, but I don't know if there will be a mineral that can meet the demand.

"In the end, there is no route that can continue to descend in the range covered by the terrain detector, so it can only be like this......" Ye Qi said helplessly, he was originally quite angry, but now he was hit by reality.

Bai Qi thought for a while and said, "Let's go out and have a look, and feel the temperature here by the way." ”

A few people prepared a little, and they activated the energy protection cover of the body, and then at such a temperature it is still more cumbersome to get out of the warehouse, open the first gate, enter a buffer zone, and then open the door of the outer warehouse after the gate is closed, so as to go outside.

The Gecko can withstand the current high temperatures, but the facilities inside cannot.

As soon as you leave the Gecko, you can feel how terrible the hot environment is, even if it has a protective cover, it feels a little hot......

Bai Qi looked around, and could see the bursts of heat emanating from the ground through the faint bright light, and easily detained a shiny stone from the cliff next to him, and he couldn't figure out what it was after studying it for a long time. 【…~ABC @… Free to read]

"Old Ye, what kind of stone is this?"

Ye Qi came over and took a look, "A mineral similar to red crystal, the density is not very high, if it is before the end of the world, this one is estimated to be able to sell for a lot of money, after all, it is mined from an unprecedented depth." ”

"So it's useless?" Throwing it in vain.

"Don't, take it back and be a sample." Ye Qi said, and took the fist-sized stone from Bai Qi's hand.

Lao Zhang walked back and forth, dark, silent, and high temperature, which was the only feeling, holding a bone knife in his hand, he picked at the rock wall, in addition to the hard rock, there were some strange textures of soil, on the whole, there was nothing unusual.

"That forty won't talk nonsense, why can't I see anything strange?" Lao Zhang said casually.

Ye Qi said, "It's hard to say, after all, that kind of depth is something we haven't set foot in, every meter down is unknown, and it's hard to say what kind of changes will be......"

Several people found some stones and soil, which were considered to be research samples after going back, but in fact, this kind of behavior is useless, even if they find precious mineral reserves, they cannot be mined in batches, and the most useful thing now is the kind of minerals that can be forged weapons as forty said, and there is no need for anything else, and now neither equipment nor technology is enough to support research in new directions.

Bai Qi is still a little more playful, the samples he collected are all the kind of gems with color and sparkle, and this collection is a little unbearable, and he soon made a bunch of them, more than the total amount collected by Lao Zhang and Ye Qi, and smiled embarrassedly when he returned to the storage box of the Gecko.

Ye Qi asked, "What should I do next?" Go back or continue to spin at the bottom of this crevice? The terrain detector covers a range of only a few hundred meters, and the crack in the ground stretches for several kilometers, and there is no telling where there is a path to continue down. ”

Bai Qi shook his head, "Go back, go to the No. 2 target point." There are still about 10 kilometers to go before the depth described in forty is reached, and based on the current width of the crack, it is estimated that even if there is a downward path, it will not reach the expected depth. ”

Ye Qi was stunned for a moment, then he looked carefully at the cliffs on the left and right, and said that he was really careless, and at the same time he had a new understanding of Bai Qi, although he felt that he seemed very casual after entering the crack, but he always paid attention to the relationship between the depth and the width of the crack......

Returned to the gecko and began to return, this time Bai Qi and Lao Zhang did not waste time, began to meditate on the spot, and began to absorb rich energy with a specific breathing and breathing method, until it completely reached the ground, neither of them recovered from the meditation, Ye Qi did not bother, let the gecko enter the standby charging state, and used the sun that was about to go west to recharge, and he also took the initiative to take on the task of guarding.

It wasn't until midnight that the two woke up one after another, and saw Ye Qi bored looking at the sky and counting the stars, gnawing on the jerky, Bai Qi felt a little embarrassed in his heart, "Old Ye, I'm sorry for you." I wanted to absorb the rich energy for a while, but I didn't expect to settle down. ”

Ye Qi shrugged his shoulders, signaled that it was no problem, and delivered the food to the two of them.

While eating, Lao Zhang said, "Actually, I am considered to be clean, when the city lord enters the meditation, the surrounding aura pulls each other, so I also enter the state of meditation." ”

Ye Qi was puzzled, "Instructor Zhang, it stands to reason that your strength is stronger, why can't you easily enter the decision?" ”

Lao Zhang shook his head, "It has nothing to do with the level of strength, there are many factors that determine whether you can enter the determination, normally speaking, if you want to enter the concentration, you must be completely free of distractions and enter a completely ethereal state, because I myself also have a lot of thoughts and questions about cultivation, so it is difficult to achieve that state, and talent is also a major reason, many people are born with easy to empty their minds, experience, education, and cognition of things...... There are many reasons for this. ”

After chatting for a while, Ye Qi operated the gecko to drill into the crack in the ground and cling to the wall, so that there was no need to worry about safety, and the three of them could have a good rest.

Maintaining the energy shield underground is also quite energy-consuming, and Ye Qi has to use his ability to control the Gecko, so no one is easy, and it is still necessary to have a good night's sleep.

The distance from target point 1 to target point 2 was much closer, and it only took about four hours to arrive the next day.

After checking the energy, it was very sufficient, and there was no need to spend any more time to recharge it, and after finding the huge crack in the ground, he drilled directly into it according to the best entry point observed by Yang Tianfu.

With the first experience, the descent speed this time was much faster, and Bai Qi had lost his curiosity about the scene in the cracks in the ground, so he didn't waste time this time, and directly started to meditate and practice, but Lao Zhang didn't, sitting next to Ye Qi to accompany him, and it was not good to let Ye Qi do boring driving alone after all.

There is something to do, and the time flies relatively quickly, and before you know it, it has reached 25 kilometers, exceeding the depth of the No. 1 target point, and according to the current width of the cliffs on the left and right, 30 kilometers should be no problem.

Bai Qi also stopped cultivating, and the three of them fell into excitement again.

After more than 25 kilometers, the situation outside also changed, and the data on the screen showed that the temperature had exceeded 1,500 degrees......

"Old Ye, I've read the remarks of some scientists, shouldn't there be some magma layer underground? We've gone so deep, why haven't we seen magma yet? Bai Qi suddenly asked.

Ye Qi smiled, "The magma layer is just a conjecture statement, and scientists have divided it into different levels according to speculation, such as the well-known crust, mantle, outer core, and core, of which the main component of the crust and mantle is silicate. Whereas, the main component of the outer core core is iron-nickel. The earth's crust is a solid silicate, the mantle is a solid or colloidal silicate, the outer core is liquid iron-nickel, and the inner core is solid iron. The Earth's crust is 17 kilometers thick and average, and at the junction of the crust and mantle, there is an interface made of molten rocks. In the past, it was often called

It is the upper mantle, which is now mostly called asthenosphere. This is where magma originates. Of course, this is just speculation and conjecture, because no one has penetrated it before. Now the temperature outside has far exceeded the temperature of the magma, but where is the magma? The only thing that can be confirmed is that the deeper you go, the higher the temperature. It is not known what the limits of the gecko are. ”

Soon the gecko came to a position of 31 kilometers and stuck on the cliff, and the probe found that there was still enough space below, so it had to stop here before it reached the end.

After all, the established depth has been reached, so let's go out and see the situation first.

The three of them came outside again, and as soon as they came out, they felt the heat of the fuss, and unconsciously strengthened the energy output of the protective shield, which made it more comfortable, in addition to the ultra-high temperature, it was also a little difficult to breathe.

Jumping back and forth on the bulge on the cliff, digging out some stones with a bone knife from time to time to observe, and doing more than 20 minutes in a row, I didn't find any stones worth paying attention to.

Bai Qi couldn't help but be a little disappointed, feeling that forty might have really shaken himself.

Just as he was about to return to the Gecko, he heard Ye Qi shouting.

"Come to me!"

With the voice, he found Ye Qi's location, and continued to borrow strength on the cliff, and came to him as quickly as possible.

At this time, there was a dark blue stone in front of Ye Qi, about the size of a football, and it could be seen from the depression in the wall that it had just been dug out.

Ye Qi didn't explain much, waved the bone knife in his hand, and slashed at it, and several gaps suddenly appeared on the bone knife, which is enough to prove that this stone is extraordinary!
