In the mine cave, the passages are vertical and horizontal.

The two of them walked down the mine cave. Along the way, they saw a large number of wreckage and corpses, and encountered many bugs. Fortunately, these bugs were of low grade and could easily deal with them with the strength of their mechas.

After about ten minutes of walking, the two of them arrived at a wide place.

The girl raised the height of the filler device a little, and suddenly the whole space became much brighter.

Looking around, it looks like an underground city.

The girl said, "This is the place for miners to rest and eat."

"Yeah!" Li Qing nodded and said, "I've seen the video taken by my father, but I haven't come."

"It's the first time I've been in!" said the girl.

The underground mine cave is a forbidden area and a very dangerous place. Except for miners, outsiders are not allowed to enter.

The building in the rest area has collapsed, with bugs everywhere, and some bones are buried in the wreckage. Obviously, these bones are left by miners.

When Li Qing saw the remaining bones on the ground, he felt even more worried, "I hope my father is fine."

Immediately, Li Qing said, "Why don't the miners run out?"

"How do I know?" said the girl, "Maybe, the mine collapsed and I can't run out."

Li Qing looked at the situation around him and found no living person or useful clues.

“What should I do now?”

"Continue to go forward!" As the girl spoke, she asked the mecha to project a light curtain and said, "Look, I have a map!"

"Oh?" Li Qing saw the map and his eyes lit up and said, "Why didn't you take it out earlier?"

"You didn't ask!"

Li Qing was speechless, he thought, 'I should have thought of this little princess with a map.'

Li Qing walked forward two steps, stood beside the girl, and looked at the map in front of the girl.

This is a very complex map with roads above, and the roads connect underground areas. In addition, some dangerous areas are marked on the map.

The girl pointed to the map and said, "This is just a topographic map of mine No. 36, look at these places."

"Yeah!" Li Qing looked at the map.

The girl continued, "Look here, this is a virtual transportation channel, this is an underground rest area, and we are in one of the rest areas."

"This is the titanium ore area, this is the uranium ore area, this is the blue crystal ore area, this is the crystal ore area."

"Look here, this is the Lingjing Mining Area!"

"Ling Jing?" Li Qing stared at Ling Jing, his heartbeat accelerated a little.

Spirit crystals are also called immortal stones by some ancient civilizations. This is a very pure life energy that can be used as energy or absorbed by the human body.

For warriors to practice, they need a large amount of spiritual crystals.

After the warrior absorbs the life energy of the spirit crystal, it can be converted into primordial power to enhance the warrior's power.

The girl said, "I guess, the main purpose of the Zerg is these spiritual crystals."

"Yeah!" Li Qing expressed his understanding.

The girl pointed to another area and said, "This is the central area of ​​n36 area. The central area has complete living facilities and some spiritual crystals are also stored. More importantly, the central area also has a complete defense system."

Li Qing understood this after hearing this.

"You mean, if the miner wants to find a safe point, he will go to the central area."

"Yes!" said the girl, "if the Zergs did not break through the defense network in the central area, they would be safe, with the energy and food reserved in the central area, they could live in it for five years."

"Five years!" Li Qing breathed a sigh of relief and said, "I hope my dad is there too."

The girl said, "Don't be happy too early. The road ahead is not that easy to walk."

"Well!" A trace of worry flashed across Li Qing's face.

The mine cave has been destroyed by the Zerg, and many passages have collapsed. Along the way, both of them have used high-tech tools to open the way and break through obstacles.

The girl said, "Now, I just hope that there are fewer collapsed channels and we can open the way with drilling tools."

“How far are we from the central area?”

"If it is calculated as a straight line distance, it is about 1,100 kilometers."

"Uh!" Li Qing smiled bitterly.

This is normal. The meteorite star is a hundred times larger than the Tianqu star. Such a star has extremely complex internal space.

"Gurl!"

Li Qing's stomach rang.

"Hehe!" The girl smiled softly, took out a piece of barbecue from the storage space, threw it to Li Qing, and said, "Eat something!"

"good!"

Li Qing was not polite either. He took the barbecue, opened his face mask, and bit the barbecue in big mouthfuls.

“Eating is really ugly!”

"You can't wait!"

"Hmph!" The girl snorted softly, took out a pack of snacks, and started eating.

Li Qing glanced at the girl and said, "Your eating behavior is not very good."

"Ah!" the girl shouted, grabbed a slight rushing gun, raised her hand a little, and only heard the sound of gunfire, a bullet hit Li Qing's mecha.

"bump!"

Li Qing was shocked by the powerful shock force and retreated repeatedly.

"You're crazy!"

The girl raised the gun in her hand.

Li Qing was depressed. He thought of his girlfriend and thought to himself, "You can't reason with women."

Immediately, Li Qing looked at his mecha again and saw a shallow hole on it. However, the impact was not great, so he secretly breathed a sigh of relief.

The two of them made a fuss, ate a little, and continued to move forward.

"It collapsed again!"

The two stood at a closed intersection, and the front was sealed by a large amount of mud and stone.

Li Qing took out a detector, detected it, and said, "The collapse position is relatively long, about 2,000 meters."

"There is no choice but to change one way."

The girl said, clicked on the map and said, "Look, we have two choices, one is to go to the magnetic energy mining area and the other is to go to the lithium mining area."

"Lithium mining area?" Li Qing muttered, saying, "Lithium mining area is too dangerous, so it is better to avoid it."

The mines in the starry sky are completely different from those on the life star. Some mines will become very active and very dangerous.

For example, in the starry sky, you can encounter planets with pure gold and planets with pure diamonds.

On the life planet, the danger of gold mines is not high. If you encounter a planet with pure gold in the starry sky, you should be careful. There may be dangers on such planets.

Meteorites contain rich mineral resources. On the surface, the danger of meteorites is not high, and millions of people live in meteorites.

However, only miners who go deep into underground mining understand that underground mines are full of crises, and if you are not careful, you will die.

Among them, lithium mining areas, titanium mining areas, uranium mining areas, these mining areas are very dangerous places, and a large number of miners die every year.

Of course, mining in dangerous mining areas has also been very considerable.

Li Qing heard from his father that the lithium mining area is very dangerous because the environment in the lithium mining area is very active and prone to explosion.

The girl said, "If you don't go to the lithium mining area, you can only go to the magnetic energy mining area."

Magnet ore is also a very rare ore. Magnetite is also very widely used and can be used to make anti-gravity flying boards, speed cars, interstellar sports cars, spacecraft, etc.

After the two decided, they moved in another direction.

After walking for about dozens of miles, the two of them came to a rare gem area.

When Li Qing saw the rare gem, he stayed there.

"Diamond, grandmother's fate, sapphire, obsidian." Li Qing was shocked, "There are so many gems?"

"Tsk!" the girl curled her lips and said, "It's so strange!"

Li Qing said, "Miss, I am not like you. I grew up in a honeypot. I have never seen so many gems since I was a child."

"Do you want it?" asked the girl.

"Of course I want to!"

"Then you can dig some away."

"Dig some away?" Li Qing was a little moved, and he asked, "Can I bring these gems back to Tianquxing?"
