"There are two more important issues." Qin Guan said: "The predecessors should pay attention to the main support structure of the pit when introducing magma, and the main support structure of the pit cannot be collapsed in a large area, and the Ministry of Science has calculated that the damage to the support structure is controlled within 7% and will not cause the stratum to collapse." ”

Sikong Poor: "Well, it's not very difficult to lead magma, less than seven percent...... This one is a bit of a hassle, but don't worry, we've got you covered! ”

Peiqingdong asked: "We put a lot of gas in the pit, will there be any reaction when we encounter high temperatures?" Or, if the gas flows outside with the magma, will it affect the composition of the planet's air? ”

Pei Jingdong's scientific knowledge was also learned in the past three years in the Star Striking Committee.

"No, it won't." Qin Guan said: "The Interstellar Element Research Institute has done similar experiments, and the experiment has found that high temperature and violent explosion will consume the gas, and the element will lose electrons when exposed to high temperature, and become another unknown inert element, named the element of cyanide." ”

"yes, I see."

Qin Guan said: "The second, and last question, is also the last link of this operation.

"Three seniors, after you lead the magma to the three star merchant bases, you must keep an eye on the immortals and captains in the bases, don't let them escape, if there are escapes, see one and destroy the other, you can't leave them alive, and you must not let them go to report the news to the general fleet."

Sikong Poor: "Understand, intercept their captain and immortal." If we want to create accidents, we need to do our work well. ”

Yin Zhizhi half-jokingly said: "I promise to complete the mission of Qin Guan Xiaoyou!" ”

Qin Guan: "The seniors are too polite to be. ”

Yin Zhizhi: "Haha, it's all for this planet, we don't distinguish between each other, young and old, and cooperate with all our might!" ”

"Let's go!"

Qin Guan: "Okay, let's go!" ”

Eight men came out from behind the boulder, flying or running, and quietly sneaked to the entrance of the pit.

"These guards outside and the germanium miners who are resting in shifts will be left until the end and then destroyed, and they will be handed over to Pei's seniors." Qin Guan whispered.

Pei Jingdong is a sixth-level realm, and it is not a problem for one person to deal with these guards and miners.

"Okay, let them live a little longer." Pei Jingdong replied softly.

Entering the pit, eight people split into three paths.

Qin Guan, Chen Throwing Fly, Pei Jingdong turned left; Xue Weiyi, the east gate is blessed, and the Tibetan bow is to the right; The two seniors, Sikong Poor and Yin Zhizhi, flew down the wide main passage shaft of the mine and flew deep underground.

The Lightweight Helmet of the Stealth Armor is soundproofed, and it speaks softly inside the helmet mask without the sound being transmitted to the outside, allowing you to communicate with confidence through a miniature quantum communication device.

"The route in this pit is really complicated enough, fortunately, we used a small robot to explore it in advance, and we also used a computer to generate a three-dimensional map, otherwise we would have been stunned in it!" Dongmen Youfu followed behind Xue Weiyi, sighing as he walked.

Xue Weiyi: "You are the biggest, concentrate on the aisle, pay more attention to your surroundings, and talk less!" ”

Blessed is the East Gate: "...... This section is still in the upper layer of the mine, and this part has been emptied by the germanium tribe, and there are no germanium miners~. ”

Xue Weiyi: "What if I encounter it and hit your invisible belly headlong?" ”

Blessed is the East Gate: "...... I'm pretending to be a wall of air? The kind with elasticity. ”

Xue Weiyi: "......"

……

……

Qin Guan and Xue Weiyi's two teams, respectively along the predetermined route, there are multiple lifting shafts in the mine, and there are four "lifting cabins" with the largest transportation capacity in the main passage, similar to human elevators; In other parts of the mine, there are also fixed points of lifting shafts and lifting cabins.

Qin Guan quickly found the target lifting shaft: "Let's take this down." ”

Pei Jingdong asked slightly confused: "If we take this, won't we be discovered?" ”

Qin Guan: "Well, there is a possibility that we will be discovered, but they can't see us.

"If you are discovered, just kill the other party.

"The most important thing is that the deepest part of this pit has been more than 5 million meters deep, and the operation layer we are going to have is also more than 200 to 3 million meters, which is a straight vertical distance of 300 kilometers, not counting the winding roads in the mine, if you only run on two legs, it is estimated that you will run until tomorrow morning."

Pei Jingdong was stunned for a moment: "So deep? ”

Qin Guan: "Yes, this pit, they are about to dig the lower mantle. ”

Chen Tofei added: "The deepest pit has been dug to the lower mantle, and it is almost to the core. ”

Pei Jingdong gritted his teeth and said, "These robbers! ”

The three of them stepped into the elevator and quickly descended into the ground.

After about half an hour, the lift cabin came to a halt and was docked at a depth of about 200 kilometers underground.

The elevator was quiet, very dimly lit, and in the distance, the sound of machinery digging rocks and the humming of crushing rocks could be faintly heard.

"There are no Germanium Clans out there."

The three of them walked out of the sound drop cabin lightly, and walked along the anthill-like mine in the direction where the noise came from.

Pei Jingdong looked around curiously: "The mine cave is more spacious than I imagined!" The width of this passage is two or three meters high, and it is so strong and complex, and how did they dig it out with such a large amount of work? ”

Chen Throw: "Maybe the germanium people are the best at doing this." ”

Pei Jingdong: "It's like a giant metal mechanical ant......"

"It's like locusts or termites in the stars, they scourge them everywhere they go, and moth our planet into such a mess. ”

"Hateful indeed."

Qin Guan didn't speak, took out the high-pressure liquid canister, wrapped the small liquid canister in a customized extended and widened invisible glove, and began to spray and release the gas.

Last night, he went to the map of the Great Wilderness Star again, and asked Reddish to order five pairs of special size gloves, which can wrap the liquid canister in the gloves, and only expose the gap of a nozzle at the index finger part, and can spew out the gas in a very covert way.

Now, for Qin Guan's various strange custom requirements, Reddish has become accustomed to it, and no longer refutes or pretends to be confused, and has been able to respond to requests.

Just now, Qin Guan and the others gave three gloves to the three seniors, eight people, and ten gloves were enough.

……

Pei Jingdong asked softly again: "The gas will corrode the lifting shaft and the lifting cabin together, how will you get out later?" I can fly out with the two of you, but what about Ah Fu and Xiao Xue? ”

Qin Guan smiled: "Senior Pei, you forgot, I can use the space technique to take them out, it's just hard senior, you have to fly out of the lifting shaft." ”

Pei Jingdong was immediately relieved and smiled: "Small things, as long as you are safe." ”

As he was talking, there was a team of engineering mecha in front, lined up in a column, along the passage of the mine, and drove in the direction of the lifting shaft.

Each engineering mech is nearly two meters tall and has six metal support legs connected to roller-like tracks between the legs.

This structure can make the mecha adapt to the ground environment of various complex potholes, and can move quickly and flexibly when encountering flat ground, and switch feet and legs to cross when encountering potholes or ascending stairs.

"Shhhh

Qin Guan said softly, and the three of them all clinged to the cave wall, leaning against the side, each holding a liquid bottle in their hands, and spewing out a high concentration of pure water at these engineering mechas!
