"it!"

"It's so easy to use, too."

The edge of the North Fourth Ring Road.

Inside a half-collapsed building.

Night Ten, who was squatting next to the window, was excitedly fiddling with the tablet in his hand.

Not far in front of him, a quadcopter drone with a camera hanging was hovering outside the window.

This is the latest equipment launched by the scientific expedition group after the quadruped robot - "Y-1 Firefly" quadcopter UAV.

The drone uses A3 aerospace aluminum produced by the Bucky Aluminum Factory, the battery uses a solid-state hydrogen battery produced by the Lister Factory, the neural access components are produced by the black box of Vault 117, and the carbon nanocircuits and operating equipment are modified by the universal wrist-borne computer "VM".

The price is not expensive, only 1000 silver coins, which is about equal to half a miner type I exoskeleton.

Since the equipment was independently developed by Vault 404 and does not need to rely on imports, the purchase threshold is very low, as long as the contribution points reach the "citizen".

Due to the use of lightweight materials, the weight of the drone is only 73% of that of a drone of the same size in reality, but the protection power has been increased by 50~70%. Not only that, but the long battery life of the solid-state hydrogen battery allows it to hover in the air for up to 12 hours.

If the user is paranoid about the amount of power, the user can also choose to connect a group of batteries in series on the basis of the original battery pack.

The positioning of this equipment is a close-range tactical reconnaissance drone, and because it is mounted on a neural access device, it is recommended for the Department of Intelligence.

The camera assembly is made of recycled materials from pre-war surveillance equipment, and the resolution is so high that you can still see the stones clearly from a distance of hundreds of meters.

To sum up in one sentence.

That's a lot of!

"Awesome, right?" [Persuasion], who was standing on the side, said with a smug smile on his face.

Ye Shi couldn't stop praising it.

"Awesome."

Spicy is a real beef pie!

Said smugly.

"Not only that, if you are an intelligence department, you can also directly connect the brain computer to operate the flight of the drone, which is much more flexible than manual operation and automatic cruise!"

"Damn?! Can you also access nerves? Night Eleven looked at him in surprise, "Dude, what are you doing in reality?" ”

Said Hurricane, who was standing by with headphones on.

"I remember it was an auto repair?"

He listened to what mosquitoes said in the group, and recently Goblin Technology has recruited a few younger brothers who are majoring in auto repair, ready to study engines or something.

"The auto repair major is 'deadly', and I am an electromechanical major." He smiled shyly and said.

Night Ten sighed.

"I think no matter what the profession is, it's awesome to be able to make this thing."

He said with a smile.

"Actually, it's okay, this thing is not as exaggerated as you think, not to mention that I do it in reality."

Tempest asked, "Did you write this control program?" ”

Quan Jian shook his head and said.

"How is it possible, I can't write code, not to mention that the compilation language in the game is a mess of garbled code, I suspect the production team didn't do this seriously at all."

"So how did you ......?"

"The control program and carbon nanocircuit were provided by Yin Fang, the head of the scientific expedition group!"

Night Ten then asked curiously.

"What about the battery?"

"The battery is a solid-state hydrogen battery from the Lister plant! The shell and main structure are made of A3 aerospace aluminum! ”

I answered all the curious questions of Ye Shi at one time, and as I spoke, I couldn't help but sigh with emotion.

"It's much easier to build an airplane in the game world, with a 24-hour ultra-long battery life and direct control by brain-computer access...... I can't even think of it in reality. ”

In reality, most of the rotary-wing drones are based on lithium batteries, and the flight time is mostly about 30 minutes, although they can also achieve 2~5 hours of long stay in the air, but that will make the volume of the battery very bloated.

Or like the Perimeter 8, you can do it for 13 hours with eight propellers and two fuel tanks.

Under normal circumstances, if there is a need for more than 2 hours in the air, the fuel engine is directly changed and the fixed wing is on, which is basically out of the category of small UAVs.

The ability to make a small quadcopter drone stay in the air for 24 hours is probably only possible in the game.

Hearing the emotion of the newcomer in front of him, Tempest and Night Ten glanced at each other.

Boy.

It's no wonder that this equipment is not displayed in the NPC Shop with a Goblin Tech card.

Dare this goblin technology to be responsible for designing a look?

Tempest: "...... So what is your role? ”

The persuasion smiled slightly, and his expression was quite proud.

"I copied our company's drone in and changed it!"

Ye Shi was stunned.

"Ah......h Is it really not an infringement? ”

Persuasion hehe smiled: "It's okay! Quadrotor drones don't all look like this, it's okay without a LOGO, and maybe you can advertise to our company after the public beta. ”

I'm not afraid of losing my job, and Night Ten and Tempest don't know what to say.

Night Ten returned control of the drone and tablet to Tempest, who had put the neural access device on his head.

The biggest use of this thing is reconnaissance.

For example, the perception system reports the general direction, and the intelligence department operates the drone to lock the specific coordinates.

The two tried a few times, and the cooperation was quite tacit, and the scope of active investigation was at least doubled compared to before.

Seeing that the drone he designed was so easy to use, he was also full of joy on his face, and he was already thinking about designing an improved model in his heart.

"How about a bombardier underneath? Remotely control bomb dropping! ”

Night ten's eyes lit up.

"Yes! I'll see the punishment! ”

Tempest, who was wearing headphones, nodded.

"Indeed, it is possible to dive and drop bombs...... However, will the addition of a bomb dropper not affect the maneuverability of the drone? ”

Persuade the fight to smile and wave his hand: "It's just a load of one or two kilograms, what can you do!" Don't worry, I'll leave this to me! ”

Yashi gave a thumbs up happily.

"Brother steady!"

"Hey, hey, steady batch!"

The three of them were excitedly exchanging ideas about how to make the drone more punishable, and Lao Bai, who was carrying an ammunition box, walked over from the staircase.

Resting the ammo box on the ground, he looked at Night Ten and Tempest.

"The mission is coming, get ready, we'll leave in three minutes."

As soon as he heard that there was a task, Ye Shi suddenly stood up excitedly.

"Coming to work?"

Lao Bai said with a smile.

"The caravan we sent to Boulder City has returned, with five office employees and a guard in addition to the six players. Our mission is to cover the VIP's passage through the xenoactive area from the West 4th Ring Road to the North 5th Ring Road, where there is suspected to be a large amount of xenomorph activity. ”

"Covering the caravan on the way back?"

Ye Shi, who was still excited, suddenly shivered and said embarrassedly.

"Uh, can I request a temporary absence?"

Fang Chang looked at him and teased.

"Scared?"

Ye Shi said with a red face.

"What does this have to do with fear?"

"Don't worry, according to my observations, Fuji Teng is not so careful, I see that she also praised Fang Chang's strategy yesterday," Lao Bai patted Ye Shi's shoulder, smiled and squeezed his eyebrows, "Isn't this giving you a chance to perform." ”

"."

Quit smoking and look left and right in confusion, not knowing what was going on.

The old man who was standing on the side looked at the wind.

"You're going on a mission, so I'll withdraw first."

Retracting the drone's gale and taking off the headset on his head.

"Do you need me to send you?"

"No, it's just a matter of a few steps, anyway, the monsters on the road have been cleared by you, I'll just walk back by myself!" He smiled and continued, "But you, be careful on the road. ”

Tempest nodded.

"Well, you too."

……

Three days have passed since the wave erupted.

Over the past three days, battles have been fought large and small, with players and xenos fighting street by street and building by building on the ruins between 65th and 68th streets.

Perhaps because of the death of the "Corrupt Knight", the "Empress" hiding in the ruins threw a mouse, although the offensive of the wave in the past three days has never stopped, but both the strength and the number are much worse than the first day.

The frontal battlefield is at a stalemate.

Chu Guang could feel that the tide was trying to consume the living power and ammunition in his hands through wheel warfare.

At the same time, a large number of creepers were crossing the ruins and infiltrating the flanks of his position.

Of course, Chu Guang would not watch them go around his back, and decisively sent a hunter team to purge those creepers who tried to cross the defensive line.

In this battle, the performance of the Hunter Guild can be said to be quite fruitful. In just three days, more than 200 creepers and nearly 20 tyrants were killed!

Among them, the Cattle and Horses squad alone killed 27 creepers and 4 tyrants.

And the player with the strongest individual combat power is undoubtedly the garbage king, in this uneven, rugged and complex street fighting environment, guns are not necessarily better than claws.

Especially against crawlers who jump up and down.

According to the statistics of VM, the garbage gentleman who acted alone killed 9 creepers with only one "person" and won the MVP of the game in one fell swoop!

In addition to him, the other players who returned from Yuanxi Town to defend and support also achieved good results in the hunting operation.

According to Xiaoqi's statistics, the average level of players above LV10 has increased by 0.7 in the past three days, and the level of middle-level players between LV5~LV10 has increased by 1.5.

Even Chu Guang, who was sitting in the rear, followed the mix.

"What happens if the genetic sequence is 20% progressive?"

Putting down the tablet in his hand, Chu Guang looked up at Heya, who was sitting opposite the scanning table.

However, Hea's answer disappointed him.

"I don't know."

Chu Guang frowned and said, "Isn't there a way to predict?" ”

Hea made a helpless expression.

"The selective expression of DNA touches the most mysterious areas of the life sciences, and even in the era of prosperity, it is at the forefront of research."

"So you can only take one step at a time?"

Hea nodded.

"That's all it can do for now." valley

Although it was a regretful tone, Chu Guang always felt that there was a trace of excitement in this guy's eyes. This feeling is as if the strange things that have happened to the docking two times have been strange, no matter what happens again, they will not be surprised, and even want to step on the gas pedal to accelerate to the end to see what will become in the end.

Is this guy using himself as a guinea pig?

But the power that fills the whole body is not bad.

Moving his shoulders, Chu Guang put on his shoes, got up from the scanning bed, and handed the tablet in his hand back to Heya.

"If there's anything new to discover, let me know in time."

In the past, he was worried that the players would level up faster than him, but now Chu Guang hopes that his level up will be a little slower.

Let at least one or two top-notch players walk in front and explore the path so that they can cross the river by feeling the stones.

As a result, now, he has become a stone in the river, racing all the way on the road he never imagined.

But he couldn't control it if he wanted to upgrade slowly.

Chu Guang has gradually discovered that sharing his experience from players is not affected by distance, and as long as the overall strength of the players improves, he will grow with it.

Even if he stayed in the vault.

Heya didn't know what Chu Guang was thinking, and she didn't care at all.

She smiled slightly as she took the tablet from Chu Guang's hand.

"No problem!"

"Don't worry, I'll leave it to me!"

Although he couldn't rest assured at all, Chu Guang could only trust her professionalism.

……

The sun rises in the early morning.

Stepping on the morning dew on the ground, the caravan returning from Boulder City finally arrived at the outpost.

The players' emotions were quite calm, and Xu Shun's expressions were okay, but the few new employees who came back with them were not so calm, and they all had expressions on their faces for the rest of their lives.

It's really just that little.

They almost won't come back......

The world outside the giant wall is terrifying.

Looking at the paradise in front of them, several people couldn't understand how these hillbillies survived in the suburbs.

It's outrageous!

Seeing the crows that appeared at the south gate, many players showed happy expressions on their faces.

"Boss Crow is back!"

"Great! Mushroom soup again! ”

"Woo woo, the ramen has risen to 6 silver coins!"

"The barbecue too! Two silver coins and three strings have become three silver coins and two strings! ”

"I can't afford to eat."

Ramen and barbecue have gone up in price?

Raven's eyes lit up when he heard this.

Excellent!

Wouldn't her mushroom soup also go up?

Listening to the coaxing of everyone, the tail with a bandage on his head suddenly touched his stomach.

"Well, I'm hungry again all of a sudden."

Sisi, who had a bandage wrapped around his right hand, glanced at his tail helplessly.

"The Ah Tail in the game and the Ah O in reality are completely two people."

The tail cocked the corners of his mouth triumphantly, and he didn't care about it.

"What does it matter! The meals eaten in the game don't fit into a real stomach, and I've heard that eating more can speed up wound healing. ”

Siss: "I've only heard that blood sugar can hinder wound healing. ”

Sesame Paste looked at the two who were still idle worriedly.

"You'd better go to the infirmary."

Fujito also nodded and said worriedly.

"There was so much blood last night...... It's better not to be too reckless. ”

"It's okay, it's just a little injury," Si Si gave them a handsome and reliable look and gave them a thumbs up, "It'll be fine tomorrow!" ”

happened to come out of the south gate, and at midnight the chicken glanced at everyone and asked strangely.

"What about the bear?"

"You say meat."

Fang Chang looked away and said meaningfully.

Its words...... This time I was finally brave. ”

When the group returned, they encountered a little trouble, and the number of xenos on the edge of the Fifth Ring Road exceeded expectations. And not just creepers, but also tyrants and butchers.

When dealing with the tyrant, Tail and Sisi were slightly injured, but the problem was not big, and they could be cured by returning to the training pod for a day of rest.

But the operation also exposed a very serious problem.

The Vault's individual anti-armor capabilities are still lacking.

The portable bazooka currently used by players is mainly the Iron Fist captured and copied from the Legion.

This kind of bazooka is still relatively effective when dealing with light targets, and it can also pose a certain threat to some light power armor.

However, it can still be a bit difficult to deal with a tyrant with "high armor and high health", and it usually takes two or three shots to take out one.

Not to mention dealing with monsters like the Rotten Knight.

This is a reminder to life pro gamers that "the Vault needs a portable bazooka with a higher penetration".

For example, RPGs.

The mosquito who has already made the recoilless cannon and armor-piercing shells is not a big problem, he has already got the "critical" drawings and formulas, and Goblin Tech will soon come up with a more reliable individual anti-armor weapon than the 37mm heavy cavalry gun!

The Mosquito Brother, who sees Steelworks 81 as a competitor, has set a FLAG on the forum, vowing to show the Toilet Guy and the Athlete's Foot the true strength of Goblin Technology.

In addition, what happened to Fujito and his party last night also gave players a wake-up call.

Over time, the xenomorphs in the wave will leave the large force and gradually spread beyond the battlefield, which Hea calls the "discrete effect".

Thanks to the sacrifice of flesh, xenogeneous research in Vault 404 is +1.

After a brief understanding of what had happened last night from Xu Shun, Chu Guang instructed him to take the new employees to the Changjiu Farm, hand them over to Luka to settle down, and then went to the front.

Since last night, the fierce battle between the front line and the wave has entered a white heat, the 125 players who died in the first night have just been resurrected, and another 66 players have been sent back to the forum.

Some of them have even been resurrected for a few hours, so it's not too miserable!

The gunfire rang out all night, and the gunfire did not stop from dark until dawn.

Chu Guang knew very well in his heart that if he wanted to win this war, the real key was not on the front line, but in logistics.

In order to meet the supply of ammunition, he even shut down the production line of fertilizer.

The sudden wave completely disrupted his plans.

Chu Guang originally planned to gradually transfer part of the production capacity of the industrial zone to civilian use before the end of spring, but who would have thought that this spring ploughing was less than halfway through, and the wave suddenly broke out.

If the opponent is a predator, that's fine.

Fighting with marauders will not only replenish a wave of prisoners of war, but also capture a batch of loot.

The simultaneous growth of social labor and social wealth is simply a win-win situation.

However, the opponent is the tide.

A sudden burst of bullets went out, leaving only a large pile of corpses, neither prisoners nor trophies, and it was a completely loss-making deal.

It really gave Chu Guang a headache.

The problem of the fiscal deficit will not be solved.

Even if he wins this battle, he will be poor......

……

The war continues.

On the sixth day of the wave, the battlefield was already stinking, and mutated flies, rats, and cockroaches had become new troubles.

The players' physical fitness is good, except for the intelligence department and the perception department, there is basically no effect, but those NPCs are uncomfortable.

Some of the immune-poor guards even switched to the plague.

Yin Fang had to temporarily put aside the work of the scientific expedition team and set up a mobile medical station in Brown Farm, which was closer to the front line, to accommodate those patients who came down from the front line.

Chu Guang exchanged all the points he had saved for an intermediate-level blind box, but fortunately, he drew some antibiotics and antiviral drugs to control the epidemic.

However, this is ultimately a palliative rather than a cure.

In order to prevent the corpses from continuing to decompose and form a larger-scale plague, Chu Guang could only separate fifty new members of the physique and strength systems, wear protective clothing and gas masks, and use three wheels to load the corpses from the North Fourth Ring Road to the outside of the Fifth Ring Road and transport them to a farther place.

Front-line command post.

Chu Guang summoned Brown, the owner of Brown Farm.

Although Old Brown neither wanted to come out of the farm, nor did he want to see Chu Guang's face, he knew very well that he had no right to refuse.

Without wasting time in greetings, Chu Guang looked at Old Brown and got straight to the point.

"I've heard that Boulder City has a way of making a nutritious paste from the nibblers."

"You've been doing business with Boulder City for so long, haven't you ever thought of using the corpses of the devourers?"

Hearing Chu Guang's words, Brown's trembling face couldn't help but have a bitter smile.

Take advantage of it?

It's that simple.

With his head down, Brown said resignedly.

"My lord, using the corpse of a devourer is not just enough to get a piece of equipment, it also needs to consume a lot of electricity."

"What's more...... We've never seen such a big wave before. ”

Even if the nibbles are the least disrespectful of xenos, they are still dangerous when they form a scale, and few survivors will sit idle and provoke them.

Most of them are forced to shoot at them.

In order to use the gnazers as industrial raw materials, technical issues aside, it is necessary to have cheap enough bullets and electricity in the first place.

The former means that the labor force is abundant and the supply chain is stable, and the latter means that the industrial facilities are relatively complete.

If these two problems could be solved, Brown Farm would have been industrialized a long time ago, so why should there be such a grievance?

Otherwise, at the cost of N chips, it is better to produce a chip than to simply buy it from Boulder City.

The nutritional paste is not always subsidized with money.

Brown Farms did not have a large enough market or the ability to export what was produced further afield.

To put it bluntly, it's just a small survivor colony of a hundred or so people.

Even now, with a population of two or three thousand in the northern suburbs, the huge infrastructure and the support of "unlimited QE" have only forcibly ignited the flame of industrialization.

Chu Guang touched his chin and fell into deep thought.

"That's a problem."

Maybe I should talk to Liszt.

However, this guy is now focused on two things: copying the KV-1 exoskeleton and opening up sales.

In order to invest in the factory and support his own war, he already owes a lot of debt to the Bank of Boulder City.

Chu Guang was embarrassed to continue to squeeze him anymore.

Leeks can't always stare at a piece of ga, and wool can't always stare at a head.

Win-win is win-win, if you want to win all the time, you still have to raise it.

Just when Chu Guang was deep in thought and Old Brown was trembling, the captain of the guard team walked in from outside.

"Your Excellency!"

Chu Guang looked at him.

"What's the matter?"

Wrench gave a military salute and loyally reported, "A group of merchants from Boulder City are outside, claiming to be your guests and wanting to meet you. ”

Thinking of the phone call Shu Yu had made to him before, Chu Guang's eyes suddenly lit up, and he immediately said.

"Invite them in!"

Wrench: "Yes!" ”
