My apocalyptic heroine has come true

"Xia Xiaochi."

Fang Ming switched the screen to the direction of the little heroine.

At this time, Xia Xiaochi was sitting on the steps of the Ark Shelter, quietly eating his lunch.

Hearing Fang Ming's call, she looked up with a small spoon in her mouth.

"How's your leg?" Fang Ming asked with concern.

"My legs feel much better..."

Xia Xiaochi lifted his left leg, which was wearing a mechanical exoskeleton.

It takes at least three months for a broken tibia to heal completely.

But as long as he wears the fluid neural exoskeleton, the fact that his broken leg has not healed will have no effect on Xia Xiaochi.

"...Would you like to take it off and see?"

Xia Xiaochi held a small plastic spoon in his mouth and asked Fang Ming in a low voice.

"No need..." Fang Ming changed his words, "But then again, you can take it off and let me see."

"it is good……"

Xia Xiaochi's face flushed pink. She bent down and carefully took off the silver boots on her legs.

The fluid neural exoskeleton can be removed in the same way as taking off shoes.

Simply unzip the shoe, grab the ankle, and gently pull outwards to remove it.

The girl slowly exposed her delicate feet. The arch of her foot was very tight, and her toes were curled down due to tension. The smooth surface of her nails had a shell-like pink luster.

As Fang Ming's gaze fell, the tender pink toes were hooked in the air.

Fang Ming's Adam's apple moved.

"…He's recovering quite well."

The extent of bone recovery is not visible to the naked eye.

Fang Ming's vision has been completely blinded by Xia Xiaochi.

After a pause, he remembered his business.

"If there's anything you want, be sure to tell me."

The growth rate of Xia Xiaochi's health value is indeed very random.

Fang Ming could only try his best to meet her needs in all aspects, and the rest was just waiting patiently.

Holding the 31 energy points in his hand, Fang Ming turned on the upgrade buttons of the other two devices.

When the Ark Shelter is upgraded to LV2, in addition to the communicator and turret that can be upgraded, there are two indoor devices that can be upgraded.

They are drone combat groups and dispersal lights.

This thing called the Dispelling Lamp... Fang Ming felt that he couldn't use it for the time being.

At present, there is no artillery attack around the Ark Shelter, and the level of mutant species at night is far from enough to destroy the walls of the Ark Shelter.

Therefore, the only effect of upgrading the dispersal lamp now is to add some warmth to the mother and daughter downstairs...

The higher the level of this thing, the greater the energy consumption.

It would be better to use the energy points on the blade.

I took a look at the weapons that had been hanging in the game store for more than half a month.

Fang Ming weighed the price and finally decided to upgrade the drone first.

Chapter 79: Shooting kilometers is also very good

"boom!"

The barrel of the steel behemoth trembled suddenly, and blazing tongues of fire tore through the smoky night sky.

In recent days, after Fang Ming's continuous debugging and improvement, the ammunition for the "reinforced road-based artillery" has begun large-scale production.

The proportion of potassium nitrate in the improved artillery shells was increased to 80%, and the high-pressure compaction process of the small module production workshop was used to greatly improve the strength of the black powder produced by Fang Ming's hands.

As the caliber of the gun increases, the filling volume of a single shell increases to 800 grams, and the energy density of the compacted warhead reaches 5MJ/kg, which is about 50% more powerful than traditional black powder.

However, compared to modern high-explosive bombs, black powder still has fatal flaws.

The biggest problem is its striking distance.

Even though the maximum range of Fang Ming's machine gun has been increased to 20 kilometers, due to the low fuel propulsion of black powder, Fang Ming can only fire the shells to a maximum of 5 kilometers.

This is the limit of what black powder can do.

If you want to break this limit, you either have to switch directly to energy point filling, or give up black powder and look for other raw materials.

"Brother Fang Ming, a five-kilometer launch is pretty good!"

Compared to Fang Ming's fear of insufficient firepower, Xia Xiaochi, who has always had a good mentality, was very satisfied with this.

When they first started building the shelter, they could only use the method of 'clamping' rat heads to collect energy points bit by bit...

Now, every shot fired by their machine guns can make the mutant species within a five-kilometer radius of the shelter tremble.

It has changed from a one-sided defense against invasion to a hunter in the dark.

Xia Xiaochi is already quite content.

“…Just make do with it.”

Fang Ming studied it for a few days, but he realized that the materials at home were really limited, and there was only so much room for improvement. There was no point in studying it further.

Shaking the machine gun's operating lever, Fang Ming aimed the muzzle of the roadbed turret at a distance of five hundred meters.

76mm shells are no joke like 20mm caliber ammunition.

This thing is filled with 800 grams of gunpowder alone, and the weight of the entire shell even reaches a terrifying weight of 9 kilograms.

If you fire a cannon within ten meters, it's no different from self-destruction.

Therefore, Fang Ming moved the target of attack to five hundred meters away.

Assuming the hit rate is similar, that location is safer for the shelter.

“BOOM! BOOM!!”

He fired a few random shots.

Fang Ming quickly turned the camera over to take a look at his spoils.

In those craters, pieces of shattered energy crystals lay quietly.

Compared with the nitric acid sugar bomb made by Xia Xiaochi, the burning speed of black powder is much slower, but it wins in terms of absolute quantity advantage.

If we continue to harvest at this rate...

It would take less than half a month to collect 5000 energy points.

Of course, there is a prerequisite for such a harvesting speed...

That is, having enough metal.

It is true that Fang Ming has a ton of black powder, and he can also load more than a thousand rounds of 76mm ammunition like this.

But...the metal demand for shells and bullets is also astonishing.

At present, all the metal in the Ark Shelter is collected by Xia Xiaochi and two other residents.

Even though Fang Ming specifically asked them to pick up more junk metal for decomposition, the recycling speed was still too slow.

Fang Ming even wanted to tear down the steel plate walls built inside the Ark Shelter and use the steel alloy to make artillery shells.

But then I thought about it and decided to give up.

This method can't make up for the metal consumption problem, so it's better to try another way...

Just like.

Go find the administrator of Shelter 2737 and make a deal.

It just so happened that Fang Ming was very interested in developing wind turbines.

It would be great if we could also "trade" the raw materials for the generators and the technology for manufacturing them.

"Xia Xiaochi, take good care of the house tomorrow. I'm going out for a while."

"Ok?"

At this time, Xia Xiaochi was busy setting the table.

This was the first time she had eaten at the table in all the days she had lived in the Ark Shelter.

As the small modular production workshop produced more small plastic furniture, Xia Xiaochi's living facilities became better and better.

After listening to Fang Ming's words, Xia Xiaochi looked up at the screen in confusion.

"...Are you going to go out and play with your other sisters?"

Xia Xiaochi asked in a low voice.

Those eyes sparkling under the dispersing light actually looked aggrieved.

Like a kitten left at home by its owner, this look moved Fang Ming for a moment.

"no……"

Fang Ming came back to his senses, "What are you thinking about???"

"Didn't you say you were going out..."

"I mean, I'm going to Vault 2737, and I'm going there by drone."

"Oh!"

After hearing what Fang Ming said, Xia Xiaochi realized that he had misunderstood.

During this period of time, I have indeed had quite a lot of 'misunderstandings' with Fang Ming.

Ever since starting the 'video chat' with Fang Ming, Xia Xiaochi discovered that he had a strong desire to explore Fang Ming...
