Half a year has passed.

The bunker has been expanded three times.

The first time was when Kaisheng couldn't stand this cramped space environment, so he pulled Romy to do it together.

The second time was when everyone cultivated Yuan Neng to enter the level, and most of them were gradually dissatisfied with their living space, and then dug together.

The third time was completely different from the first two.

Freedom Troopers, Cave Hunters, Wandering Traders......

In fact, there are still a lot of free people in the devil's cave who are not controlled by the front bureau.

It's just that most of the time, these people have a fixed course of action and rarely change.

Because the Black Iron Battle Fortress was destroyed too suddenly.

Most of the freelancers who took the route of the Black Iron Battle Fortress did not get the news.

Most of them still made their way through the odds and tried to make their way to the Black Iron Castle.

As a result, they arrived at their destination, and they were all dumbfounded.

The huge black iron battle fortress is gone.

The idea of letting them transfer, trade, rest, and so on all come to naught.

Then they found out.

A bunker not far from the Black Iron Battle Fort actually exists.

As a last resort, they applied to enter the bunker.

Staying in the Demon Cave Wilderness, even if it's just the outer part of the bone layer, is still dangerous.

But anyone with a normal IQ will find a way to find a place to stay.

Not to mention rest, at least you won't starve to death.

The space in the bunker is not large, and although there are not many people coming at first, it is really a little crowded after a long time.

Considering the future of the bunker, it may be possible to create an area in the bunker where you can trade accommodation.

In this way, not only can you communicate with the merchants, hunters, and warbands, but also greatly guarantee the safety of the bunker.

This is the third expansion.

After the third expansion, the bunker no longer resembles a sentry and becomes more and more like a small village.

Although the sparrow is small, it has all the organs, and there is no shortage of anything that should be there.

Coupled with the help of Kaisheng and Romi, he cherished the material several times, and his fame spread.

So the popularity gradually increased.

Later, the Ministry of Science and Technology's [Yuan Energy Extractor] was born, and the Tao of Yuan Energy came suddenly.

Everyone was very interested in this transcendent path that suddenly appeared.

According to the public information, even if you don't have an excellent Yuan Energy talent, as long as you persevere and exchange time for talent, you can reach the extraordinary in a few decades.

And Yuan Neng also has a strong auxiliary effect on the original three-series extraordinary power system.

The requirements are low, the effect is large, and it is difficult not to be excited.

The only thing that can be regarded as a demanding requirement is that there must be a [Yuan Energy Extractor].

But the new things often come out in one word - expensive!

It's too expensive to buy, and the next batch has not yet come out on the part of the Ministry of Science and Technology, and all orders have been completed on the other side.

This is not a good thing for the majority of independent travelers.

To everyone's surprise, the small bunker actually sold the [Yuan Energy Extractor].

At the beginning, many people thought that eighty percent of them were fakes, and they were 100% taking advantage of the heat.

But after the bunker's first [Yuan Energy Extractor] was sold, things took a 180-degree turn.

People with good deeds also compare the [Yuan Energy Extractor] produced by the bunker with that of the Ministry of Science and Technology.

It was found that although the extractor extracted by the bunker factory was lower than that of the Ministry of Science and Technology, there was almost no big difference.

All of them can use [Dilla Crystal] to replenish energy, and the interface is exactly the same.

Prices range from one-half to one-sixth of those of the Ministry of Science and Technology.

But it doesn't matter, the important thing is that there is a huo here.

When Li Boyang learned about this, he couldn't help laughing.

The materials used by the Ministry of Science and Technology to produce the [Yuan Energy Extractor] will definitely not be too precious because of the need for popularization.

But if you want to talk about low-grade, it really doesn't count.

And the [Yuan Energy Extractor] on the bunker side, the main material is [Pure Stone].

That's right, it's not [Pure Crystal], but [Pure Stone].

It is a very large amount of associated ore that is bred from [Clear Crystal].

The [Clear Crystal] contained in the clear ore veins under the bunker is only about three tons at most.

But the associated [Chengjing Stone] can have about 30 million tons!!

[Pure Crystal] has certain characteristics of [Clear Crystal], and can indeed become the main framework of [Yuan Energy Extractor].

However, due to the upper limit of the material, this thing will be changed to [Dila Crystal] for about 3~10 times, and it will eventually collapse because it cannot withstand the impact of energy.

Because of the inferior material.

A [Dilla Crystal] can be used about 300 times on the [Pure Stone Version: Yuan Energy Extractor].

The daily limit of ordinary people's use is mostly three times.

In other words, a piece of [Dilla Crystal] can be used for 100 days, and 10 pieces are 1,000 days - and this is the upper limit of the lifespan of the [Pure Stone Plate Yuan Energy Extractor].

To put it bluntly, the inferior version of the [Pure Stone Yuan Energy Extractor] is more like a disposable.

Even if it can be exchanged for [Dilla Crystal] to replenish energy, it is just looking at it.

The top-of-the-line [Yuan Energy Extractor] is made of essentia, marrow, and blood, and in most cases does not require energy replenishment at all, and the lifespan of the use is almost unlimited.

High-end, the main material uses [Clear Crystal], because [Clear Crystal] has a natural attraction to Yuan Neng, in exchange for [Dira Crystal] there is no limit, even if the natural attenuation of [Clear Crystal] is considered, the service life should be 60~100 years.

The mid-range ones are probably produced by the Ministry of Science and Technology, and the main materials are nothing more than [lapis lazuli and white stone], [white bone beads], and [hyperpolymer alloy derived secondary porcelain...... Anyway, the final service life is about 5~50 years.

The lowest grade is naturally the main material of [Chengjing Stone].

But the lowest-grade ones are the most powerful, because they can be popularized!

Although the production of the Ministry of Science and Technology is not expensive, [hyperpolymer alloy derived secondary porcelain] can be synthesized in large quantities.

However, in order to produce [derivative secondary porcelain], it is necessary to produce [high polymer alloy] first.

The price of [derivative secondary porcelain] is not high, but the problem is that [high polymer alloy] is too expensive.

This comes and goes, even if [Derivative Secondary Porcelain] can be synthesized in batches, no matter how low the price is, it will not be cheaper than [Chengjing Stone].

However, it is possible to make a very cost-effective product at a mid-range price.

Li Boyang is happy to have a prejudiced opinion about this.

A complete economic ecosystem is bound to be both high-end and inferior.

If you have money, you will naturally buy good uses, and if you don't have money, you can buy inferior disposable products, and you can barely get by.

Everyone can use the [Yuan Energy Extractor] that they can use.

Yuan energy will really blossom and bear fruit on the human side.

It will even gradually spread from the inner world to the surface world, and eventually all human beings will set foot in the path of Yuan Energy.

He wondered, if the time really came, would he be able to collect the fate?

After all, the great changes in the world are almost equivalent to his single-handedly promoting development.

But presumably that's what happened in the distant future.

Now, Li Boyang is more concerned about the radial diamond-shaped crystal in front of him.

It was a pity to let the top-level [Yuan Energy Extractor] be retired, and Li Boyang simply used it as a material for refining the [magic weapon].

The [Yuan Energy Extractor] is actually the [Waidan] on the Xiuzhen side, and among the many novels he read in his previous life, it is not uncommon to use [Waidan] to refine [magic weapons].

It can even be considered relatively common.

Most of them also have the ability to condense external energy, but the more important functions are attack, defense, and unique special abilities.

Li Boyang used Yuan Energy to refine more than 3,000 kinds of materials in total, and selected the most suitable thirty-six kinds of them.

Disassemble, refine, and optimize the [Yuan Energy Extractor], remove the belt and other decorative debris, and finally refine it into a projectile-sized [Energy Auxiliary Unit].

Thirty-six kinds of elemental energy refining materials are then used to surround the [Energy Auxiliary Unit] in a specific way and method to form a special release, cache, and burst...... Equal energy circuits, well, in other words, they can also be called runes.

In the final stage of the formation of the energy circuit, it is also necessary to drip Li Boyang's own essence blood, supplemented by Yuan Energy to repeatedly wash and mark his mark.

From start to finish, it went smoothly and there were almost no major mistakes, but it still took too long, and it didn't work out for more than three months.

Originally, Li Boyang thought that everything would be like this, who would have thought that the accident would come unexpectedly.

Because in the final stage, Li Boyang suddenly remembered that he still had to add [spirituality] to the [magic weapon].

This one hit him stuck.

There is no such thing as a [magic weapon] in the Ashisheng realm, and naturally there is no so-called [spirituality].

But if you think about it, it's not that there are no alternative ways and means.

For example, capture a special body of the demon cave similar to the elemental life, not destroy its life, but take its life core, and then use the yuan energy to wash and purify it day and night.

Because the pertinence between the Yuan Energy and the Demon Cave is too strong, this must be a long process, and if the Demon Cave creatures are brushed into Yuan Energy creatures, one will be accidentally shattered, and the special life form will be killed.

After success, throw it into the [magic weapon] and act as the spirit of the magic weapon.

Li Boyang just thought about it for a while, and then gave up directly, it took too long not to mention, and if he didn't do it well, he burped and gave up all his previous efforts.

If this were to happen, he would have to vomit blood.

The rest of the methods are similar, and there are very few that are not only very simple, but also have a very high success coefficient, but the time is too long, and it can take tens or hundreds of years at every turn.

Li Boyang can't afford to wait.

So he looked at the ...... of his previous life Artificial intelligence.

With Li Boyang's current ability, in a state of high mental concentration, he can maintain a palm-sized range, and his spiritual power can reach the nanometer level.

Originally, this ability was useless, it took time to concentrate, and the scope of influence of the palm size was too small to be affected by the outside world, and the wind and grass would withdraw from the [nano state].

Later, when I thought about it, it seems that this can be used to rub the CPU and APU by hand?

Don't get me wrong, Li Boyang was not a genius in the AI world in his previous life, and he didn't understand CPU design or anything at all.

Even if he has the ability to rub the chip by hand, let him really rub it, the knowledge level is not enough, and he can't rub it if he wants to.

Fortunately, the development of the world is fast enough, and there are [Di boards] similar to tablets in the previous life, and naturally there are chips.

However, in Cadilla City, it is not called a chip, but [enlightenment template].
