Best luck

The handles and pedals are very flexible, and they didn't have to make much effort, so they let the drilling machine work, and drilled underground at an angle of 45 degrees. After a while, the drilling machine went deep into the desert. The mud is passed along the surface of the machine to the back, allowing the mud to flow back and forth, so that the hole at the back is re-sealed by the mud when the drilling machine is moving forward, which not only solves the problem of transporting the mud, but also makes the forward speed very fast due to this virtuous cycle.

Especially in the loose quicksand layer, Liang Yong and the others did not use much effort, and the drilling machine moved forward rapidly, and it advanced more than 100 meters in less than a quarter of an hour. At this time, Hongluan reminded them that the depth was not enough to continue drilling for 200 meters. , They increased the angle and continued downward. After passing through the quicksand layer, they walked through the fixed soil. The resistance was much higher. When encountering rocks, they needed to step on their feet faster, but the difficulty was still within the controllable range. Just like they are running in the park for morning exercises, they are slightly out of breath but not tired.

There is still some time before the destination. Xuanyuan took this time to introduce the detailed characteristics of Qiankun Ding to Liang Yong. After hearing Xuanyuan's introduction, Liang Yong was not more surprised. According to the rules and allusions in the world of comprehension, the soul-locking orb is a magic weapon left by an immortal, and the Qiankun Ding is also a magic weapon left by a fairy, but it is of a high level and belongs to the category of high-grade fairy weapons. It is natural to use it in the mortal world. It has a lot of magic.

Cultivation and technology are two parallel systems, both of which allow human beings to improve their ability to conquer nature, but cultivation focuses on the cultivation of the human body, while technology uses the forging of materials to create various tools for human use. The two systems At a certain stage of development, there will be commonality. The magic tools refined by the cultivators are actually the result of material changes, and the development of science and technology can also help the cultivators use tools and medicines to increase the speed of cultivation. **

As an ancient intelligent human being, Xuanyuan's soul was fused with the Qiankun Ding, and after some study, he understood the meanings of various talismans on the Qiankun Ding, and displayed the various magical characteristics of the Qiankun Ding, and cooperated with Hong Luan to make the Qiankun Ding temporarily It is not difficult to transform into a drilling machine, but the high-grade immortal weapon can be changed in thousands of ways and has powerful energy.

Liang Yong knew that the Qiankun Ding was used by Xuanyuan, and he didn't regret it. Although the fairy weapon is good, it can't play a one-ten-thousandth effect in his hands. The soul orb was taken away by Hong Luan, and he didn't have the slightest regret. In his opinion, it was the best use of everything, which was the same as his usual peaceful style of dealing with things. Reasonable, I am happy and relaxed, and be a hands-off shopkeeper.

After encouraging Xuanyuan, Liang Yong returned to the terrible situation he was about to face. He was already very close to the core of the underground explosion, but there was no news of Shu Yan. Hong Luan couldn't judge the scene without seeing the core The situation, Shu Yan's life or death is uncertain, like a huge boulder weighing on Liang Yong's heart, making him feel uncomfortable from time to time.

Suddenly, everyone's feet sank, the pedals became heavy, and it took a lot of effort to step on them, and the forward speed of the drilling machine suddenly slowed down.

Liang Yong and the others didn't know what was going on, so they stepped on the pedal hard, but the forward speed still didn't increase much, and it took several minutes to advance less than ten centimeters.

"Master, don't worry, we are penetrating the outer metal shell, which is as hard as the metal shell in the pit. Although the thickness has been weakened, it still requires a lot of energy to pass through." Hong Luan explained in a timely manner. , making everyone both excited and nervous.

The three of Liang Yong accelerated their pedaling speed, sweating on the tip of their noses and focusing on their expressions. After working hard for a quarter of an hour, they suddenly felt light. The drill bit finally pierced through the hard surgery. Liang Yong found that the shell was more than one meter thick. Hong Luan He also said that it is relatively thin here. Isn't the metal shell in the big pit several meters thick.

But before the three of them were happy, they felt the drilling machine tremble violently and was pushed back by a strong force. It retreated several meters before being blocked by the soil layer. Through the observation hole, they could see a stream of hot gas coming from the hole they drilled. It is this gas that pushes the drilling machine back, and when the gas encounters the surrounding soil, it makes a crackling sound, just like frying something in a frying pan, watching the soil layer burn red Peel off layer by layer, and finally there is no dust left.

Liang Yong and the three of them were stunned. The temperature was higher than that of a steelmaking furnace. Fortunately, they were sitting in the top-grade fairy artifact Qiankun Cauldron, otherwise they would be a wisp of green smoke, roasted by the hot gas.

After waiting for 3 minutes, the gas weakened and the internal and external pressures were balanced. Hongluan said happily: "There is a huge cavity where we drilled, which saves us a lot of time. Everyone, go in quickly." She didn't say anything. Wrong, the inside of the metal shell is not full of cavities, most of it is lava that continues to cool. Although it is not as hard as the shell, it is still very strong. It takes a lot of effort to drill through, and it will waste a lot of time.

The drilling rig entered the metal casing again, and everyone was stunned by the sight in front of them. It was a dazzling sea of ​​red, with scorching gas flowing around and whistling sound. It won't be red, but the hot temperature makes them red, and the drilling machine feels very relaxed when sliding on it. These rocks are as soft as mud, and they sink when pressed.

Looking as far as the eye can see, this is a space with a radius of one kilometer, surrounded by fiery red, and the three of Liang Yong are stunned for a while, not knowing where to go. Is this a beautiful and advanced base before? It's like entering a certain place. a crater.

Hongluan instructed Xuanyuan to put a long detection pointer deep into the lava, and after detecting in every direction, Hongluan instructed: "This is not the core area yet, let's continue drilling down along the east side!"

Liang Yong didn't understand why she had to go to the core area. Only through Hongluan's explanation did he understand that the design of the base took into account that if the base explodes, it will be the most terrifying nuclear explosion. This place will become a real purgatory on earth. No one will be spared, so a sturdy escape cabin that can withstand nuclear explosions was specially built during construction. The escape cabin is not big, only a dozen cubic meters, but it can accommodate three people to hide in it. One day's usage is guaranteed, and the base's black box is also here, and many important scientific and technological achievements are backed up in the black box.

As long as people outside can dig out the rescue capsule within 12 hours after the explosion, they can save lives and get the black box to minimize the loss. Hongluan guesses that Shu Yan and the others are most likely hiding in the rescue capsule , so we must go to the core area to dig out the rescue capsule as soon as possible, begging to share
