Zheng Changchang saw that Lao Mai was fascinated by the map, so he explained: "These state-owned coal mines in our city have almost hollowed out all the underground coal seams within the urban area, and then dig down, from a geological point of view, the surface of the urban area is very dangerous, and it is possible to ensure that the whole city may subside ten meters, which is worse than the Tangshan earthquake, and the subsidence has always been much more powerful than the earthquake." ”

Section Chief Xiaobi also interjected to explain that this time the shutdown and transfer of behavior, that is, the city has made a determination to shut down all coal mining enterprises, protect underground mineral resources, and prevent geological disasters.

Regarding the words of Section Chief Xiao Bi, Lao Mai nodded in agreement, he is a pure earth attribute person, a typical ground mouse, so he can not understand it very well.

This coordination meeting was held until noon, and the main content was still about the issue of resettlement and transfer of workers to the community, because there had been a motion for a long time, and this meeting was just a contact, and the specific docking work had to be left for future operations.

After the meeting, all the participants went to a nearby roadside food stall restaurant called the People's Commune Canteen, and had a casual light meal.

After going back, Lao Mai has been thinking about those underground tunnels, and when he looked at the map, he suddenly had an idea in his heart, that is, he intended to find a time to go down and see what kind of environment it was now.

Although the coal mine has been closed and sealed, it is not a problem for Lao Mai, who can drill into the rock layer, to go down the mine at all.

Nowadays, the difficulty of compression and condensation of liquefied true elements is getting higher and higher, Lao Mai has long wanted to change to a high-efficiency environment, no longer drill mountain nests, and has emptied the soil aura of many mountain bags, and many mountains have shown signs of soil lack of water and cracking, and trees are dry and yellow, and if you suck it down, it will endanger the main peak of the Wuxiang Mountain Range.

After a few days, after Lao Mai stopped worrying, according to the coal mine tunnel distribution map that he had memorized in his heart a few days ago, he found a closed coal shaft on the edge, carried a tool satchel on his back, and performed the Qi Guarding Body Method, transported the soil escape technique, and melted into the coal pit from a soil pit.

In fact, Lao Mai has worked in the Technical Transformation Section of the Municipal Economic Commission and the Industrial Section of the Development and Planning Commission for so many years, and he has also gone down some coal shafts, which is somewhat of a pit concept.

But this time when I came in, the feeling was completely different, first of all, there was no light, and it was dark everywhere that I couldn't see it visually, and secondly, the air was so turbid that I couldn't breathe normally, so I could only turn to internal circulation to enable fetal breathing.

Last but not least, he felt that there was an earth aura that was stronger than the ground, something he had never felt like this before.

Originally, he could use the divine sense enhanced by the Soul Seeking Technique to see things, but for the sake of convenience, he still brought the super strong engineering long flashlight commonly used by Ah Guang, and used his eyes if he could, and said it when he couldn't use it, anyway, there was no hindrance.

Although the coal shafts in this fringe area are not as standardized as other large coal shafts with a strong degree of regularization, it seems that the mining is relatively standardized.

Walking down the track, the side wall vault made of reinforced concrete is not like the coal shaft dug by stealing it, and the pit is supported by wooden sticks and plates at will, and there is often a danger of roofing and sheet gangs.

Although he walked in one foot deep and one foot shallow, he also walked very fast, and nearly an hour passed, and he was about to reach the deepest mining face, and saw that there were steel frames or logs everywhere.

Lao Mai used a large flashlight to shine on the bottom of the pit full of water, and after thinking about it, he put away the flashlight, transported the qi protection method, and disappeared in place in an instant.

He had already dived into the underground soil, and his divine sense scanned everywhere, and found that in the clay rock layers, there were layers of raw coal sandwiched between the rock and soil layers, but the coal content was low, and most of them were coal gangue.

Lao Mai has known since he was a child that the local coal quality is far less than that of northern coal, with many impurities and low combustion value, no matter how cheap it is to make honeycomb coal, only a few people will buy it, and even the units with boilers to burn coal do not like to use, and finally can only be reduced to the internal combustion material of the clay brick factory to burn red bricks, and there is no future for development, which is also one of the internal reasons for being closed and abandoned.

He didn't care about that, he just wanted to drill around and see how much earth aura could be absorbed, anyway, this area was all abandoned coal seams, so there was no need to use it in vain.

Although it is not a bonanza, but the emaciated camel is bigger than the horse, it is all energy things, and the content of the earth aura far exceeds the surface rock and soil layer.

Lao Mai's earth escape technique was extremely fast, and he turned around in a large circle under the city in the middle of the night, determining a few center points for absorbing spiritual energy, and then retreated back to rest.

In the next few days, he went to absorb the earth aura bit by bit, and he had already discovered that when the liquefied true element was compressed by more than half, it was used to run special exercises to condense the true element, and the true yuan power needed to be more and more huge, and the earth aura absorbed from the surface soil of nature was not enough at all.

Now that he had sneaked into the coal vein, he found that the earth aura had become stronger, and due to the lack of natural supply, the true yuan power that had been helplessly weak in his body suddenly became stronger, and the power of compressing and liquefiing the true yuan had increased a lot.

Naturally, the compression and condensation speed increased greatly, and after a round of cultivation, when I looked inside, the change was almost visible to the naked eye.

In less than a week, the earth aura within the range of a circle center point was almost absorbed, and the divine consciousness felt that the black-gray raw coal seam had turned grayish-white, and even the coal gangue had become much lighter in color.

Lao Mai confirmed that this first center point had been absorbed to the critical point, and there was very little earth aura left, which was dispensable and could be given up, he took a breath of true vitality in the mud layer, and after a while, he was ready to leave.

At this moment, he suddenly felt the shaking sound of gargling in the soil around him, just like the abnormal movement that occurred during the gravity of the weathered stone, which made Lao Mai wrapped in the rocky soil layer feel like he was in quicksand.

He thought for a moment, and suddenly said in his heart: "It's bad, I absorb the essence of the earth spiritual qi, this underground is like a rock being weathered, it can't withstand the weight of the thick layer of soil on the surface, and it will slowly collapse." ”

Lao Mai's brain was spinning, so he thought of a plan, hurriedly used his spiritual power, vigorously stirred up the soil layers, and then used the proximity to the underground water source to atomize and infiltrate the water and soil into various rock and soil layers, and then hit the true yuan force like a cement dry knot, and forcibly solidified the surrounding environment on a large scale.

After a period of busy work, the main fulcrum of the underground rock and soil layer is completely firm, and there is no danger of collapse again, so he breathes a sigh of relief.

Looking at the time again, it seems that the sky has begun to brighten, and Lao Mai immediately withdrew and fled back to the villa, washed and changed clothes and rushed to work.

At night the next day, he drilled into the ground again, first went to reinforce the formation that had absorbed the earth aura, and then changed to the next center point, continued to absorb the earth aura and convert it into true yuan power, and ran a special exercise to compress and condense and liquefy the true element.

In this operation, Lao Mai learned a lesson, and will not absorb the aura of the soil first, and only strengthen the rock and soil layer when he feels the danger, but take the method of reinforcing while absorbing, just like the face of the coal mine when mining, it is necessary to dig coal while reinforcing the face of the face, so that the entire mining face will not be in danger of collapsing.

After a few months like this, the underground coal seams included in the center of the circle framed by Lao Mai were almost absorbed, and the entire underground was also reinforced like pouring cement mortar.

At this time, Lao Mai felt that the liquefied true element in the original dantian had been compressed into a ball the size of a pigeon's egg, no longer in a liquefied state, but completely solidified, and more importantly, it could not be pressed and shrunk.

Through his inner vision, he used his divine sense to see that in the center of his dantian, there was a round earthy yellow sphere suspended, as if translucent, emitting a faint light like a night pearl in the dark.

Is this the Jin Dan? Lao Mai was faintly excited in his heart, and it was time to go to the next step after the compression, he understood that such a shape of the object was just a Dan billet, and he still needed to run the last step of the special exercise to completely activate it.

He no longer remained underground, there was nothing to absorb, and he accidentally passed through the closed coal shaft to accelerate the formation of Jindan, which was a good thing that he had never thought of.

Thanks to the wise decision of the city to eliminate the hidden danger of land disasters and resolutely close the coal mine, otherwise he really would not have thought of using the abandoned coal resources underground to accelerate his cultivation and form a golden pill as soon as possible.

Finally stepping on the edge of Jindan Avenue, Lao Mai unknowingly became the first person to break Jindan for thousands of years.

Lao Mai needs to thank the city, he didn't think that the city will not thank him for reinforcing the underground in the future, but will curse him fiercely, because he has strengthened the underground like granite, and in the future, when the city-level leaders want to build the subway on a large scale in order to fight for political achievements, they will find that the construction difficulty has increased several times.

At present, Lao Mike can't manage so much, and he sweeps the snow in front of the door now, regardless of the frost on the tiles in the future.

He excitedly turned back to the villa, and at this time, there were still a few hours before dawn, first took a shower, and then climbed to Simmons's big bed, and ran the special activation technique that was condensed into the Dan method.

In fact, this is also a cultivation process from quantitative change to qualitative change, the compressed and solidified Dan billet through the guidance of the exercises, quickly from slow to fast self-rotation, originally just a weak night pearl, gradually evolved into a morning rising sun, earthy yellow also turned into egg yolk.

I saw that the activated Jin Dan rotated to a certain speed, then stabilized, and suddenly like a heart that was restored to beating by a pacemaker, it drove the true yuan force of the meridians in the body to flow on its own, and turned around.

The formation of the Jin Dan caused the dantian to no longer passively serve as a place of transit station, and from then on, it played the role of a power heart, just like the heart of the human body, Jin Dan is the heart of the cultivation of the true yuan power.

The official operation of Lao Mai's newly promoted Jindan means that he has entered the early stage of Jindan, and in terms of the grading of the Fupi Earth System exercises, it is the cultivation realm required to enter the fourth layer of exercises.
