For the construction of military bases, the United States has a wealth of experience, and basically all kinds of encounters on the battlefield have been thought of.

In this military base, there is a source of groundwater, and supplies such as food are provided by the local and some surrounding countries.

The weapons and equipment have been transported a long time ago, and in addition to guarding against the battlefield here, they can also provide ammunition for other bases in the United States.

The military bases of the United States are a huge system of warfare, and they are all related to each other.

The vast majority of the sources of weapons are produced in the United States, and a small amount is purchased from the allies.

The interior of the military base is very tightly guarded, with a facial recognition system and a security system such as passwords and fingerprints.

Ordinary people on the first and second floors are not allowed to enter, and only these soldiers on the third floor can enter and exit freely.

In this military base, a total of seven thousand people were stationed! Of these, five thousand belonged to the United States, and the rest belonged to the allies.

These people live comfortably underground, and apart from the strict requirements of training, other than a military base, it is more like a ...... Fallen hell!

There are many leisure and entertainment facilities in it, and you won't feel bored at all, except that there is no casino.

There are also more than 300 female prisoners of different ages imprisoned here, and everyone can think of what to do!

With such a small salary, who would want to come to the battlefield with frequent accidents? The United States has a mature system in this regard, and the people who come here may be a little depressed, but let them leave here completely, they are not willing to do it!

That person also knew several other military bases, and there was one of the largest ones not too far from here, and Chen Chen only needed to fly for half a day to get there.

After asking everything clearly, Chen Chen ended the person's life, and he also absorbed the whole body energy of the first person who came here!

Seven thousand?? Damn it!

……

He didn't act immediately, just like the man before, sitting in a chair in a daze, in fact, he was silently recovering from the consumption of this way.

In the evening, when there was no one to take over, he put away all the planes and tanks, closed the warehouse door, and walked towards an ordinary hangar fortress.

There is an entrance to the underground, and in the underground base, there are five exits, four of which are in hangars, from which planes and tanks can be transported.

The remaining exit led to the alternate base a kilometer away, and as for the lab, it was cut off from here.

"Hey, Bob, do you want a game of snooker? How about a 50-piece game? "There's no casino, but it's a common occurrence.

"No, I'm not feeling well today, Ming." Chen Chen imitated the man's voice, covered his forehead and said vaguely.

"Alright then, don't forget, we'll play a few rounds tomorrow."

Chen Chen shuttled through the third basement floor, which was four meters high from the roof of the shed, giving people the feeling of being in a shopping mall, not so depressing.

The people inside are gathered in twos and threes, and many more are in the recreation area, where there is all kinds of entertainment.

There is very little surveillance here, only in important locations such as exits.

After using the code obtained from the interrogation to enter here, Chen Chen's divine sense found out everything here in an instant.

There is a row of rooms, there are people guarding over there, there is an electric machine room, there is a monitoring room for the entire base, and there is a room, which is like a command place, there are a lot of communication equipment, and there is a huge sand table in it.

It is definitely not possible to destroy the power room here alone, there is also a backup power supply here, in addition to the power supply at the entrance and exit is independent, and there are three lines, which are the outside power generation equipment, the inside power room and its own backup power supply.

But this is nothing for Chen Chen!

No one could have imagined how incredible a cultivator's methods were, just such a big place, he could destroy all the power lines with a single thought, and completely lose contact with the outside world!

He had no interest in visiting here, nor did he personally experience that depraved way of life, he was just waiting, and he knew very well how many people there were, and now was the time for the shift to change, some people were fully armed, and some people came down with a relaxed face.

The last thing he wanted to see was the female prisoners who were being held, none of them were idle, for them, this was hell, life was worse than death!

……

An hour later, the third basement floor was instantly plunged into darkness!

Cursing, exclamations, flashlights, mobile phones, candles, etc. lit up, apparently, there was also a power outage here.

No one knows what's going on here, and no one notices that their companions are disappearing fast!

Chen Chen is like a supernatural person in the movie, anyone who sees him disappears in an instant, and he has been carrying two weak people in his hands, until they turn into ashes, and two more people appear in his hands.

Starting from a corner of the base, all the metal and other items that can be used are disappearing rapidly, including people!

In the refining vessel, iron ore can be refined into refined iron after purification, and Xiuzhen-grade refined iron cannot be refined with current scientific and technological means.

And after the refined iron is purified, the iron mother will be refined, this purification process can not be done by human beings, it is a kind of magic that communicates heaven and earth, the principle is unknown, who created it is not known, it can be understood as the practice of the cultivator when he realizes the Tao.

As the years passed, basically all cultivators would use these spells.

The ratio of refining is one to 10,000, that is, 10,000 tons of iron ore can refine one ton of refined iron, and one ton of refined iron can refine 0.1 kg of iron mother.

The best material for a cultivator's magic weapon is iron mother-level metal, including storage rings!

At the beginning, the system made the collected materials barely reach the level of "fine", so you can imagine how much worse his storage ring was from the normal requirements.

If you want to complete it, you need to collect the metal required for the storage ring, refine it and integrate it into the current storage ring, so that you can complete the upgrade and meet the requirements of the normal storage ring.

And at that time, the storage ring can play the role of a growth magic weapon, and then there will be no need to be so troublesome, throw materials at the core of the formation, and you can slowly grow and advance.

It would be best if there were jade and spirit stones, as long as the aura could keep up with the supply, the storage ring space could be expanded by itself!

What Chen Chen needs most now is all kinds of metals, and commonly used metals can also be used, as long as the amount is large.

After replenishing the storage ring, he still has a lot of magic weapons to refine, flying swords, armor, I don't know how much he needs.

The flying sword is different from the sword of mortals, it doesn't matter how heavy, as long as it is recognized, it is like another arm, and there is no weight at all.

But this is also relative, it can't be too heavy, otherwise a flying sword is like a mountain, who can use it?

He hadn't seen how many things there were on the first or second floors of the military base, but as long as he took away this military base and the one next to it, he should be able to upgrade the storage ring, maybe there was still left, and he could create a flying sword.

Mortal technology is still okay, especially in weapons, which are not shoddy things, and they are much better than ores when refined.

But he didn't have too many of these things, and how many women there were, besides, if he could, he would also want to use these materials when building a spaceship in the future, but he didn't know what the level of refining was at that time...
