After getting a satisfactory answer, Ye Bing asked again:

"If I want to build a barrier with the same specifications as the outer barrier of the base in all aspects, but the scale is dozens to a hundred times larger, how much energy will it take?"

Natasha paused for a moment and replied:

"At least 2440 energy will be needed."

Ye Bing nodded silently and said:

"2440 points of energy? Well, I got it......"

The reason why he asked this was because he planned to build a layer of defense on the limit of the dataization of the Doom Base.

If it can be built, it will become a complete heavy fortress.

Although the area is a little smaller, the defense ability will become extremely strong.

It's just a pity that there is still a certain distance between the ideal and the reality.

More than 2,000 energy spending.

At least for a short time, Ye Bing and Doom Base can't afford it.

As if sensing his unwillingness, Natasha took the initiative to remind:

"Commander, you probably don't need to create a defensive barrier of that scale. According to the calculations of Zhi Brain, as long as the thickness of the wall reaches half of the existing and the height is reduced by two-thirds, it can effectively block the impact of the zombie tide of about 5,000 scales. ”

Hearing this, Ye Bing's eyes lit up and said:

"Really?"

Natasha continued: "Yes. In addition, in some areas, you only need to set up certain barriers to save the cost of building the walls, and at the same time, you can improve the security of the fortress. ”

The more Ye Bing listened, the more excited he became, and nodded one after another:

"Good, good! If it's all as you say, how much energy is it estimated to need? ”

Almost instantly, Natasha gave the answer:

"About 870 energy."

Hearing the answer, Ye Bing smiled bitterly:

"It does save a lot of energy, but ...... I still can't take it out for the time being. ”

He shook his head and said boldly:

"Oops, forget it. What's there to worry about, now the ground is full of 'gold', just a few shots, isn't the energy coming in piles and piles? ”

After a while, a chime came.

Mecha Barracks LV3, upgrade complete!

After being reminded, Ye Bing couldn't wait to go in.

The first thing that caught his attention were two extra icons.

Click on it casually, and the introduction that pops up makes his eyes light up!

Finally an air unit has appeared!

Next, there is the second air class.

These are the approximate numbers for the two new classes.

Ye Bing was stunned.

He never expected that the dream of airspace in his heart would come true like this!

But......

When he saw the expensive cost of the two new troops, he couldn't help but smile bitterly.

"Alas, this price is really, making a poor bastard like me cry without tears......"

At this moment, he began to miss the old days.

Dozens of magic crystals in his pocket. You can have fun and feel like the richest man in the world.

And now, more than a thousand points of energy can't do anything.

What a happy helplessness!

But. Objectively speaking, in some specific situations, the above two types of air arms should still be quite useful.

First of all, let's take the W01 fighter as an example.

Both from the name. The shape, or the weapon, can be easily judged. This is a class designed for anti-aircraft combat.

Four anti-aircraft scorching ray guns, plus two anti-air guided missiles, a total of six weapons, enough to blow up a conventional human fighter into the sky.

With its fierce combat power, coupled with its agile flight speed, it is estimated that even the raptor mutant beasts in the sky have the power to fight.

Relatively, the weaknesses are also prominent.

The attack ability on the ground is too weak, only two high-speed pulse guns, and for ordinary humans, the effect is not much different from two machine guns.

This kind of killing efficiency is obviously not feasible to deal with the tide of zombies that gather together in thousands at every turn.

In addition, health and armor are too low to withstand many attacks. Once it is attacked by the enemy on a large scale and indiscriminately, it will have devastating consequences!

In contrast, another type of unit, called the UFO Disc, has made up for the shortcomings of the W01 fighter to a certain extent.

In terms of health, it has the same 300 HP as the Guangling Chariot. In terms of armor, it is even equipped with armor that exceeds the light Ling chariot by 10 points. This means that the XCOM disc will no longer be as crispy as a fighter.

At the same time, what made Ye Bing's eyes shine even more was the D-level energy shield force field it was loaded.

This is a piece of equipment beyond Ye Bing's cognition.

To this end, he specifically asked Natasha what the "Energy Shield Force Field" was.

Here's the answer:

"An area with an energy shield field will not be subject to non-energy damage within a certain limit of destruction for a certain period of time."

Just this sentence, Ye Bing understood it for a long time, and finally figured it out.

To put it simply, once that field is activated, either only energy-based weapons can deal damage, or only other attacks with destructive power above a certain limit can deal damage.

What does this mean?

This means that as long as that force field is activated, no matter how many bullets the opponent fires, as long as the lethality of each bullet does not exceed the limit value, then all bullets will not be able to deal damage!

How terrifying!

With this force field alone, most of humanity's individual firearms can be castrated!

Even if the bomb is fired, it will only explode on the surface of the force field, and the shell fragments will not be able to enter the force field, only the heat wave and shock wave can blow into the inside, which will resist a large part of the damage!

Thinking of this, Ye Bing was speechless in shock.

It was only at this moment that he became acutely aware of it for the first time.

The Doomsday Base and the current technology of mankind are fundamentally two completely different concepts!
