Raw materials are readily available in the warehouse, and the power supply comes with a variable adapter that can be powered by a generator or plugged into a fusion battery with a standard interface.

Like the black box that Chu Guang got from the manager's office in Vault 117, the black box here also has its own battery, and the remaining power is 98% and 99% left.

Helium-3 is a stable isotope with a very long half-life, and the losses caused by natural decay are almost negligible under normal use. Basically, as long as the battery itself is not damaged due to improper operation or other reasons, the energy will be stored for much longer than that of conventional chemical batteries.

Chu Guang instructed Guo Niu through VM to send all the materials he needed, and by the way, he also called Dr. Yin Fang, the chief explorer of Vault 404 and the head of the scientific expedition group.

As soon as he entered the door, Yin Fang's eyes almost fell out.

"Black box?! And it's two! Where did you get that? ”

S-Class Relic!

Two appeared at the same time!

Just the day before yesterday, Chu Guang got a black box, but he didn't expect that it hadn't been three days before he got two more.

Since becoming an explorer after graduation, Yin Fangti College has been archaeological pre-war civilization relics for five or six years, and it is the first time I have seen such an exaggerated situation!

Looking at this guy's insightful expression, Chu Guang rolled his eyes and threw the manual he had just picked up into his hand.

"Pick it up, will you see if it will be used?"

Yin Fang smiled.

"Would any fool use this thing...... Speaking of which, have you checked the fuel of the reactor? How many are left? ”

"There are quite a lot of accidents, about 40%."

What is the concept of 40% Chu Guang doesn't know very well, if it is a mobile phone, his charging compulsion disorder must have been committed, but a reactor with controllable fusion, it is said that 1% of the energy can be used for a long time?

I don't know if the amount of energy consumed by clone synthesis is large.

But no matter what, now that the reactor is finally in his hands, the stone hanging in Chu Guang's heart has finally been put down.

Hearing Chu Guang's words, Yin Fang was obviously relieved.

“40%？ That's good...... Don't worry about it anytime soon! ”

Without worries, Yin Fang began to operate the two black boxes.

In the drawer-like filler opening, enter the materials in turn according to the instructions, and then close the drawer. It's okay not in order, but it's a little quicker to do so.

The signal light is on, indicating that the material is qualified.

Then turn on the power and press the start button.

It's all very easy.

It's as simple as some kind of religious ritual.

Looking at the jumping numbers on the screen, Chu Guang touched his chin and said.

"The remaining time of production is 59min27s...... Why did you wait so long? ”

Next to it, another small black box that produces VMs is faster, and it only takes ten minutes to make a product.

Assuming a non-stop supply of raw materials, it is theoretically possible to produce 144 VMs a day.

It's a good thing.

VMs with processors, imaging equipment, and laser mapping capabilities can be used not only as a "vital signs monitor" in itself, but can also be retrofitted into something else.

For example, robots with laser mapping and automatic wayfinding functions.

Another example is a simple computer, and so on.

Combined with the "Neural Connection Device" produced by Dr. Principle's black box in Vault 117, as long as the materials are sufficient, the player's transformation degree can be directly increased by 10 percentage points!

Intelligence players will have a real spring!

It can be said that it is very easy to use.

Yin Fang: "I heard that the principle of the black box is to first powder the material, and then print out the parts of each component in sequence according to the spatial sequence according to the preset synthesis route, so as to generate the product as a whole...... Compared to the pipeline mode, it will definitely take a little longer. ”

Chu Guang said.

"It's the equivalent of building wheels and engines at the same time?"

Yin Fang affirmed.

"That's understandable!"

Chu Guang nodded thoughtfully, indicating understanding.

It's like a 3D printer.

However, its function is much stronger than that of 3D printers, not only to print the shape of the device, but also to print the "performance" of the material and the microstructure and macrostructure of the device, and complete the automatic assembly in the printing process.

This goes far beyond the concept of "printing".

It's more like a reconstruction of "atoms in space on the PM scale"!

Xia Yan, who was standing on the side, scratched the back of her head, she couldn't talk about this kind of troublesome topic at all.

She can repair the machine with a wrench, or use a simple workbench to machine parts, after all, the slums of Boulder City are built next to the industrial area. There are two ways out for the people there, either to work to death in the assembly line or in the workshop, or to become a mercenary with the weapons produced in the factory and exchange their lives for money.

And she happened to have walked both.

After thinking about it, Xia Yan felt that if he didn't say a word, wouldn't it seem that he was very useless, so after holding back for a while, he reluctantly interjected.

"This machine sounds weirdly good...... Can you take it apart and take a look? ”

Hearing this, Chu Guang didn't react, but Yin Fang next to him was startled like a dog with his tail stepped on, and hurriedly said.

"Don't do that!"

Xia Yan scratched the back of his head and asked, "Why?" Shouldn't this kind of thing be good research material? ”

Hearing the layman's speech, Yin Fang shook his head and said.

"It is common knowledge that the more technology-intensive the product, the more difficult it is to reverse it. To find a grain of gold from a pile of sand, you just need to sift it out. But if you were to stand on a sand dune and sort and recycle every grain of sand, it would be almost impossible...... Unless you've mastered more advanced tools and methods. ”

"And the black box of the Ark Project, whether it is the production method or the technical principle, represents the highest level of human manufacturing, it does not have any requirements for the performance of materials and the education level of the operator, or even the intelligence level, even the monkeys in the zoo can use it."

"This wishing machine can be said to be the technological crystallization of the pre-war civilization, unless it is a civilization that is far superior to ours in terms of production methods and basic science, no one can disassemble what is needed from this complex and cumbersome equipment."

Xia Yan muttered.

"I just asked casually, and I didn't say that I really wanted to tear it down...... But this thing is so difficult to serve, if it breaks, how can it be repaired? ”

"If you can't fix it, if it's broken, it's broken," Yin Fang shook his head and said, "In the academy, the broken black box will generally be sent to the museum, and maybe someone will be able to parse it in a few hundred years...... But at least not for now. We'd rather study the products made in the black box, or at least it's much less difficult. ”

Yin Fang's answer answered some of Chu Guang's questions.

It seems that even the academy does not have the ability to disassemble the technology in the black box, at most it is only the product of researching the black box.

Glancing at the timer on the screen for the last timer, Chu Guang spoke.

"It seems that there is still a little time for the mystery to be revealed...... Let's check out the buffer room next door. ”

Yin Fang was stunned.

"Buffer room? Isn't this the B3 floor? ”

Chu Guang nodded.

"Yes, Vault 404 doesn't have just one door, and I even suspect that the B3 floor gate is the real entrance."

Spatially, the doors on the B3 floor are significantly wider than those on the B1 floor, and connect the warehouse to the growing area.

What does this mean?

It means that the shelter was most likely built from the B3 floor and then extended upwards and downwards at the same time!

Of course, this was just Chu Guang's speculation, if in the lower floors, other more exaggerated exits were found, then he didn't say it.

Every time Chu Guang thought that he had fully understood the Vault and the plans of the first administrator, the Vault under his feet always brought him unexpected surprises.

Chu Guang even suspected that the designer of this shelter was a gamer.

……

Everything outside the gate on the B3 floor is unknown, and no one can say what will happen.

If the situation is optimistic, it may be the easter egg left by the first generation of managers.

If you are not optimistic, it may also be a nest of mutant rats or cockroaches.

Just in case, Chu Guang brought the power armor from the maintenance room on the B1 floor, and while bringing a nitrogen hammer and a Gauss rifle, he also took two sickle assault rifles, a bulletproof vest and a backpack stuffed with 7mm bullets.

Body armor is for Boss Xia.

Back in the maintenance room on the B3 floor, Chu Guang threw a sickle assault rifle and a police body armor into Xia Yan's hands.

"I don't need to teach you how to use it."

Putting the body armor on his body, Xia Yan easily tied his long red hair into a ponytail and picked up the rifle leaning against the wall.

"Are you kidding? I'm ...... anyway."

"The mercenary who added a chicken leg to the creeper's lunch?"

Looking at Xia Yan, whose face was full of murderous anger, Chu Guang hurriedly closed his mask, coughed and walked in front.

"Follow me."

Xiao Qi rolled the pulley and followed behind Chu Guang.

Yin Fang saw that he had no weapons, so he hurriedly chased after him and asked.

"What about me? Give me a weapon, too! In case of an accident, I can fight! ”

Chu Guang thought about it and threw the silver snake revolver hanging on the power armor to him.

"Remember to give me back."

"Just six bullets?!"

"I'll give you some more if I need it."

The gate on the console was pulled down, and Chu Guang pressed the red button.

The alarm bell rang three times in the maintenance room.

Thigh-thick deadbolts were retracted one by one, and the gear-shaped alloy door slowly rolled to one side, revealing the pitch-black tunnel.

A cold, dry breath came to my face.

Chu Guang turned on the searchlight on his shoulder and walked forward with the "Scythe" assault rifle.

The soles of your feet creak when you step on the ground, the dust here is thick, and no one has been here for a long time.

The light in the passage is very dim, which can be described as a finger that cannot be seen.

Fortunately, there was lighting on the power armor, and the other two were also carrying flashlights.

Through the light from his shoulder, Chu Guang could see a steel rail laid on the ground, as well as a few construction tools scattered around.

"There is no such tunnel on the map," Yin Fang confirmed the map through VM, and continued, "Our direction is due south, facing the subway line 12 of Qingquan City, and the straight-line distance is about 4 kilometers!" The due north direction coincides with the elevated highway out of the city, towards the outside of Qingquan City. ”

Line 12 runs through the north and south of Qingquan City, and Huayuan Street subway station is one of the stations on Line 12.

Chu Guang raised his index finger and tapped it on the side of the helmet to open the map on the eyepiece.

The orange-yellow window is projected onto the tactical eyepiece.

The nearest metro station is located in the vicinity of Bate Street, about 800 meters away.

Chu Guang had been there before, but he didn't go in, he just took a look outside, and the inside was completely occupied by the gnawers.

There are other things that are difficult to deal with.

"What if it goes north?"

Yin Fang slightly, dragging the map.

"North Side...... We are in the northernmost part of Qingquan City, and further north is outside Qingquan City, and there is no subway line on the map. ”

The tunnel runs north-south, and the exit of the evacuation shelter is located on the side of the tunnel, and after passing through the iron gate, there is a road to the south and north.

"Let's go north first."

After speaking, Chu Guang took the initiative to walk in front and led the team to the north.

After about 800 meters of progress, the tunnel came to an abrupt halt, and an alloy wall stopped in front of everyone.

"There seems to be no road ahead," Xia Yan, who was shining forward with a flashlight, turned his head to look at Chu Guang and asked, "Do you want to go back?" ”

Chu Guang stared at the wall for a while, then walked to the side of the wall and found something like a distribution box.

Pulling back the lid, he saw a grip and a circular connector.

Interestingly, the circular interface is exactly the perfect match for a small cold fusion cell.

Chu Guang's heart moved slightly, and he took out a cold fusion battery with 11% remaining energy from his pocket and plugged it into the interface.

Then, he pulled down the grip next to him.

A slight electric current sounded, accompanied by a tooth-aching grinding sound, followed by a slight tremor under the feet of the crowd.

It's like an earthquake!

"What's the situation?!"

Yin Fang looked around in a slight panic and took two steps back.

Xia Yan was quite calm, his eyes glanced at the ceiling vigilantly, and then looked ahead, his eyes widened slightly.

"It's the wall! It's sinking! ”

Xiao Qi slipped to Chu Guang's calf and said nervously, "Master, it's so dangerous here, why don't we withdraw first?" ”

"Don't worry, wait!"

Chu Guang stared at the wall in front of him.

I saw it sink slowly, and after shaking for a while, it finally revealed the tunnel behind it.

At this time, everyone realized that the wall was actually hundreds of meters wide!

It's like a whole tunnel being lifted!

"Incredible......" Yin Fang took two steps forward, a shocked expression written on his face.

Such a thick concrete structure.

To say the least, it will cost tens of thousands of tons, right?

Counting the mechanical structure, as well as the load-bearing structure below, it is equivalent to burying an aircraft carrier underground!

The metaphor may not be appropriate, but it doesn't make a difference.

Chu Guang also had a surprised expression on his face.

There's nothing inherently complicated about the mechanism.

Amazingly, more than 200 years later, it is still up and running without any obstacles!

Just as the two of them were stunned, a hoarse roar and the sound of running came from the front of the tunnel.

Hearing that voice, Xia Yan was shocked, and immediately raised the assault rifle in his hand, and opened the safety with his index finger cleanly.

"Nibbler! In front of us! ”

Before she could finish speaking, she had already pulled the trigger in her hand, killing the two nearest two in three shots.

"It seems that the movement just now attracted a lot."

Turning on the auxiliary aiming mode of the tactical eyepiece, Chu Guang, who raised the sickle assault rifle to aim, swept over with a shuttle, and the few nibbles closest to him instantly bloomed their heads and fell to the ground and were killed on the spot!

At that moment, a dangerous omen suddenly struck.

"Damn, it's the creeper—" A hint of panic appeared on Xia Yan's face, and the memory of fear in his heart resurfaced.

But in the next moment, the creeper's head exploded to pieces.

"Don't panic, I'm here."

Chu Guang, who threw the Gauss rifle on his back and re-grasped the sickle assault rifle, skillfully switched back to automatic fire, and swept the several nibbles that rushed up to the ground.

A stump on the ground with a broken arm.

The smell of rotting fish permeated the passage.

Yin Fang, who was hiding behind, breathed a sigh of relief and lowered the raised muzzle.

Looking at the nibbler on the ground, and the dark spots and slime molds on the distant wall, his Adam's apple moved with difficulty.

"I have a hunch...... I'm afraid there are a lot of xenos in front! ”

"You don't need a hunch to do this, as long as you have eyes, you can see it," after a pause, Chu Guang continued, "The area ahead is better left to the 'players' to explore." ”

As he spoke, Chu Guang put away the rifle, tapped his index finger twice on the helmet, called up the visualization window, and edited it skillfully.

[Mission: Clear the exit of the B3 floor]

[Genre: Hunting, Exploration, Attacking]

[Note: The passage outside the entrance and exit of the B3 floor is occupied by slime mold xenomorphs, and we need to take it back from the hands of those brutes!] 】

[Released to: Hunters, Scavengers, Soldiers, and players with a level greater than LV5]

【Rewards:

For each Eater killed, 1 Silver and 2 Contributions are rewarded.

For each Martyr killed, 1 silver and 1 contribution are rewarded.

For each creeper killed, 20 credits and 20 contributions are awarded.

Per Tyrant killed......

……

】

——

[Mission: Explore the passage on the B3 floor. 】

——

[Mission: Investigate the source of slime fungus contamination in the passage of Level B3.] 】

……

A total of 5 missions have been updated in the mission channel, and players who meet the conditions of "release target" can claim them freely.

This should be a good leveling spot.

Even if it is 10,000 eaters, it is only 10,000 silver coins.

Even if you add 500 creepers, it's just another 10,000 silver coins.

In this way, players not only gain experience, but also improve their proficiency in shooting, archery, throwing, and fighting skills, and earn money.

It was just perfect!

If you can get your hands on an active extractor, you can deploy one here.

The extraction efficiency of the nibbler is average, and 10 can be used to refine 1 unit. However, no matter how small the mosquito is, it is still meat, and it is better to add up to a lot of money, than to let the corpses of those xenomorphs rot and stink in the tunnels, becoming a breeding ground for germs.

And all you need to pay is some values that can be adjusted at any time.

Thinking of this, the corners of Chu Guang's mouth couldn't help but curl up with a smile.

Since the benefits are all for the players.

This wave is even if the players win twice!

Glancing at Chu Guang in admiration, Yin Fang couldn't help but sigh.

"Your 'players' are so easy to use, too."

It is simply a model of hard-working and hard-working.

He had never seen such a hard-working Vault dweller!

Chu Guang teased.

"Looks like you've come to appreciate the essence of the game."

Hearing a word he didn't understand, Yin Fang was stunned.

“youxi？”

"Combined with the contextual paraphrase, it is the meaning of cutting leeks."

Yin Fang: "......? ”
