Du Hei looked at the iron ash mine that had been carried out, his eyes flickering.

But he didn't know.

The camp, outside the non-safe zone, surrounded by fierce beasts, naturally it is impossible to lay any cables or anything like that.

But in the camp, electricity is also generated.

How is electricity generated?

This naturally involves an energy expenditure.

In the field area, it is not realistic to take the conditional factors, wind power generation, hydropower generation.

Nuclear fusion power generation is even more impossible, after all, if a fierce beast attacks the nuclear power plant, the harm caused is too great.

But fortunately, the world at this time has undergone abnormal changes and many strange objects have been born.

Among them, various spiritual ores are one of them.

The spirit ore contains this huge amount of energy, which can be converted into electricity through a special way.

Among them, iron ash ore is a kind of energy ore that many camps are accustomed to.

The reason for choosing this ore is also very simple.

First, the energy contained in this ore is attributeless, and it is peaceful and peaceful, and it is not a problem to convert into any energy.

Second, the price is relatively cheap, one kilogram of iron ash ore, even if Du Hei buys it alone in the bazaar, it is only five hundred, and if it is official, it is even cheaper.

Third, this kind of ore has peaceful attributes, strong stability, and is also easy to store, but there are some thunderbolt attribute spirit ores, which cannot be used at all.

Compared with the spirit ore of the thunder and lightning attributes, the power carried by itself makes it difficult for ordinary soldiers to approach, not to mention that after accumulating too much, it may cause the current to ripple, causing unnecessary casualties.

On the contrary, iron ash ore, although some energy conversion may be lost, but it is not too precious to hold iron ash ore!

At this moment, the beast had already launched its second impact.

Steel walls, crumbling.

Du Hei reacted and strode into the warehouse.

On the ground, there were a lot of ores scattered, and without any hesitation, they chose to collect them.

Enough, two thousand seven hundred and fifty kilograms of ore!

Du Hei didn't have time to be surprised, and turned away.

At this time, he had already seen that except for a few soldiers who were still controlling the Thor Cannon, the rest of the people were all skillful, draped a string of bombs linked together.

The remaining hundred or so soldiers, clad in explosives connected by a lead, were still armed with laser guns.

In such a frenzy, he rushed to the area where the crack appeared, and attacked the low-level ant beast that burrowed into it with his body.

At this moment, seven or eight seconds had passed since the first overall attack of the fierce beast.

Du Hei no longer looked at those soldiers, but quickly raised his head, and locked his eyes to the only three remaining at the moment, among the attacking Thor cannons.

"Hopefully, it can be strengthened. ”

Only one thought flashed through Du Hei's heart, and his body was already bursting at full speed, like a spirit ape, and he quickly climbed a tower.

Time, two seconds passed again.

Behind him, there was already a loud explosion.

Apparently, this is a soldier clad in explosives, which someone detonated.

This means that the situation below is not very good.

Du Hei didn't dare to look back, but quickly, locked his gaze on the Thor cannon, whose barrel was hot and red because of the continuous firing.

Then, in the stunned eyes of the soldier controlling the Thor Cannon, he touched it towards its bottom position.

A hint of burning sensation came.

But what surprised Du Hei even more was the voice that sounded in his head at this moment.

【Thor Cannon】

【High Rate of Fire Gun】

【Silver Grade】

【White Quality】

[Cannot be strengthened as a whole]

[Enhancement Parts]: Core Super Array Disk

[Enhancement Success Rate]: 72%

[Enhanced Consumption]: 74 pieces of iron ash carbon.

[Strengthened]: ?

Du Hei was determined.

He had a guess.

In his understanding, after the world changed, although the scientific and technological level of human beings has improved, it has not shown a metamorphosis.

It's just that there has been a renewal in communication and other aspects.

But in the area of conventional weapons, the progress has not been huge.

But why is the Thunder God Cannon alone able to threaten fifth-order fierce beasts?

Among them, in addition to the results of his research, he speculated that it should be related to the various materials that are born from the aura in contemporary times.

Of course, this is just speculation.

He didn't know what the specifics were.

At this moment, it can only prove that the bet is right.

In the core part that makes up the Thor Cannon, allowing it to attack at such a rate of fire, there is indeed a so-called super array as the core existence.

And this array plate, with such an effect, is indeed expected, with white quality.

Without the slightest hesitation, I chose to intensify.

The Forge Phantom appears, enveloping the core of the Thor's Cannon.

It's just less than a second.

In front of Du Hei's eyes, a hint of success in strengthening appeared.

【Super Array Disk LV2】

It can increase the power increase by 1.8 times.

This is the effect of strengthening.

Before, it was only a doubling increase.

Suddenly, the tongue of fire sprayed by the Thor Cannon became even more exaggerated.

If the previous rate of fire was still like "da-da-da, da-da-da", then it has now become a real non-stop.

Moreover, the increase in power is extremely huge.

Every bullet, fired out, is like a burning meteor, originally facing the third and fourth order of the fierce beast, but also hundreds or even more bullets, frantically attacking to one place, in order to break its carapace, now every bullet with the blessing of faster speed has greatly increased penetration.

Du Hei did not stagnate in the slightest, he knew that there should not be too many bullets left now.

We must strive to get the most out of these bullets.

In the next few seconds, Du Hei strengthened the remaining two Thor cannons one after another.

After the strengthened, the Thor Cannon exerted a terrifying power, and it actually achieved the same effect as the original eight with just three forts, stopping the fierce beasts from two or three hundred meters away.

But at this time, the crisis did not dissipate.

Du Hei's gaze looked at the bottom of the tower, where the original camp was located.

At this moment, there are only twenty or thirty soldiers left, and the part of the ant beasts that rushed over with the power of the third- and fourth-order fierce beasts has completely invaded the camp.

It's just that the third- and fourth-order ones haven't entered yet, but the rest of the first-order and second-order fierce beasts have already entered a lot.

Du Hei's heart sank slightly, there was only one thing he could do at this moment, and that was to join these warriors and resist with them.

"But before that!"

Du Hei muttered in his heart, and then he strengthened the skill of summoning a velociraptor for the last time.

At this moment, every increase in combat power may add hope for life.

The Fortified Furnace is running.

This time, it seems that it is the goddess of luck who stands in front of Du Hei, and he has succeeded in strengthening it once.
