Hehe, according to the agreement, the second chapter of today's update is here! The brothers and sisters are really mighty and domineering, go on, Xiaomo likes it!

The temperature under the ground is still relatively low, and being able to raise a fire is still quite beneficial for maintaining body temperature. This point is very clear to Tang Feng, who has long mastered the "Mining Disaster Survival Manual".

The flame that was lit was not large, but it could provide enough heat and light, which made Tang Feng, who was deep underground, somewhat relieved.

With the light emitted by the flames, Tang Feng took out the military kettle, fortunately this military kettle was made of high-strength plastic, otherwise it would have been shattered in the series of explosions just now.

Just now, because of the orthopedic reasons, Tang Feng was very painful and sweated a lot, but now after settling down, Tang Feng only felt dry mouth. But Tang Feng didn't dare to drink a lot of water, the ghost knows when the rescue team will be able to dig here, this pot of water is definitely life-saving, even more important than that pack of compressed biscuits.

Putting the spout in his mouth, Tang Feng only took a small sip, and it was estimated that there were not even ten milliliters. I chirped my mouth and let this little fresh water fully moisten my mouth, so I endured the huge temptation. Confused, he tightly twisted the lid of the kettle to death, and carefully hid the kettle.

Then Tang Feng sat on the ground, swept the broken stones on the ground around his body with his hands, and then put the miner's backpack, which was already somewhat damaged, as a pillow, and then endured the pain and lay down. In this case, if you can sit and never stand, if you can lie down, you should never sit, and the most important thing is to maintain your physical strength and reduce physical exertion.

After lying down, the pain in his leg made Tang Feng simply put his consciousness into that space again, and he was in a hurry to enter just now, and he hadn't carefully understood this space.

The space is really lifeless, the boundary is not fixed, but similar to the existence of a chaotic gas, Tang Feng touched those gases with his consciousness, and found that the toughness was very sufficient, and it was impossible to break it. The ground was full of cracks, like the bottom of a dry river. The strange trees of unknown variety grew near the spring where there was no water, and under the trees, it seemed that other plants had been planted, but they were too dry to recognize their original appearance.

Aside from these things, there was nothing else in the space, which made Tang Feng wonder.

The explanation of the previous core program has made Tang Feng somewhat understand that the fundamental reason why this star core space has become what it is now is because the energy has been exhausted, otherwise, this small space would not be like this, but should be full of life.

However, the core program also said that it will take about a month or so before the core will use up all the energy, that is, the core still has at least the energy to absorb radioactive elements. But how do you control the star nucleus to absorb radioactive elements? What kind of radioactive elements can be absorbed to meet the needs of the star core? Who will answer these questions?

Tang Feng's consciousness circled around this space several times, and he couldn't figure out how to trigger the working mechanism of the star core. In desperation, Tang Feng's consciousness followed the spring that had dried up and drilled into the ground of this space. Sure enough, after drilling for a few meters, the spring was finished, and what excited Tang Feng the most was that at the bottom of the dried spring, Tang Feng found something that obviously did not belong to natural formation.

It was an earthy yellow hexagonal stone with an extremely standard form, Tang Feng's consciousness lightly touched the stone, and suddenly an earthy yellow light erupted from the stone, reflecting in the space through the spring.

Tang Feng's consciousness hurriedly drilled out, and found that there was a dim, shaky holographic light screen in the space, and there were some strange fonts on the light screen, and above the light screen, there was a holographic three-dimensional image.

Tang Feng didn't know any of those fonts, but Tang Feng knew that those fonts should be the fonts of the world of the former owner of the star core. However, that holographic stereoscopic image Tang Feng looked extremely familiar.

That image is a semicircular three-dimensional image, the plane above is slightly undulating, if Tang Feng is not mistaken, it should be the surface, because below the plane above, Tang Feng can clearly see the soil and rock layers, the most important thing is that in the center of this image near the surface, an earthy yellow point of light is flickering, and near that earthy yellow point of light, there are several unusually clear, and meandering dotted lines, how do those dotted lines look like the fat mine owner's hematite roadway schematic.

"This is" Tang Feng's eyes widened in surprise, looking at the hologram that was still shaking from time to time, and muttered to himself, "This is the topographic analysis map of this area!" That's right, it's definitely an anatomy diagram! Well, these dotted lines should be the tunneling roadway formed by the fat mine owner's hematite mining, absolutely yes, this farthest dotted line, isn't it just extending to the top of the earthy yellow light point? And above that earthy yellow point of light, there is also a huge space! In other words, the earthy yellow dot in the middle represents me? ”

As a professional who often goes down the mine, Tang Feng certainly understands how important it is to figure out the detailed structure of the underground before going down, especially the situation of the area where he operates, and he must understand it very thoroughly.

This thing is not only related to the smoothness of underground operations, but more importantly, once an accident occurs, being familiar with the underground roadway situation can greatly increase the chance of survival.

For example, if there is an accident underground, and the main roadway in this area where you are located collapses, you will definitely not be able to get out according to the normal way of walking, but if you know the situation well very well, then you may be able to go to other roadways through the return air shaft without collapse, and then ascend the shaft to escape, but if you do not understand the structure of the well, then you will definitely not know the location of the return air shaft, and perhaps you will lose the opportunity to escape.

So, opportunities are always for those who are prepared!

This sentence is replaced by underground operations, which works just as well!

These things are all learned by Tang Feng and his colleagues in his daily work, and Tang Feng has always attached great importance to things that can save his life, so this skill has long become one of Tang Feng's essential skills, just like the mage's small fireball, the warrior's attack and killing swordsmanship, and the Taoist's healing technique.

Although Tang Feng didn't know the words on the light screen, with the basic skills he had cultivated in the past two years, coupled with his understanding of the underground, especially the area where he was working and the situation of the roadway, Tang Feng could see at a glance what this hologram represented.

But how can the space filled with gas still exist on this hologram? It's been completely blown up, huh?

What's going on?

Tang Feng looked at the fonts that were obviously introduced on the light screen, but he couldn't understand them, and he was annoyed in his heart!
