"Cuckoo~"

"Brother, I'm starving to death, your plan is unreliable!"

"Who's not hungry? I'm hungry too!"

"Half a steamed bun left, why don't we split it up, half for each person."

"No! This half steamed bun is our only hope and cannot be eaten!"

"Then how long do we have to wait, I just heard a strange cry, I don't know what kind of beast it is."

"Look at the footprints and crawler tracks on this road, they are definitely traces of people!"

"Listen to me, if you wait for two hours, and if no one shows up, then we will withdraw!"

The two people's shelter was broken through by alien beasts in less than half a day. In desperation, they could only escape and wander around, looking for a chance of life.

As it happened, the location of the airdrop was very close to them, and the two quickly sensed the opportunity.

These two people were very miserable. They had to eat or drink, and the only weapons were a fire stick picked up in the woods, and a low-quality bow and arrow.

Before coming, I was hungry all day.

No weapons, no adequate physical strength, and not enough manpower.

In desperation, he could only ambush in this traffic throat, trying to snipe a few unlucky people.

"Brother, there is movement!"

"somebody is coming?!"

Both of them had surprises on their faces.

"Don't worry, first observe the enemy's situation."

The two were ambushed on the hillside, about 90 meters from the main road.

Fortunately, it was an open field, and the moonlight was bright enough, otherwise they wouldn't be able to see their faces.

A robot that was crunching on its tracks appeared in the sight of the two of them.

Its sturdy robotic arm, dragging an airdrop box steadily, drove slowly on the main road.

"Why is there only one robot, and no one else?"

"It doesn't seem to be..."

"Don't worry about it so much, there may be a large army behind."

"Rush up, grab the airdrop, and run away!"

The two didn't think much of it at all, rushed down the hillside, and kicked the armored labor robot over with one kick.

The airdrop box also crackled and fell to the ground.

"Be careful, what if you fall into the pit?"

"Look at what's in there!"

The two held back their excitement, and after arranging the airdrop box, they found something different.

"Brother, it seems that this airdrop has already been opened."

"Look, these welded seals are cracked."

"Time is running out. When the big army of others catches up, we can't escape."

"Take what you have."

Open the lid of the drop box.

Nothing but a grenade inside!

"Cuckoo~"

By the time they pulled up the airdrop cover, the fuze had already been triggered.

boom!

The flames from the huge explosion instantly engulfed one of them.

The other one, who ran faster, didn't die from the explosion, but his body was soaked in the venom from the grenade, and he died in pain and wailing.

…

farm shed.

Su Heng learned all this through the camera of Xiaohei 2.

"Is there really someone like you?" Yan Wan looked a little surprised.

This clumsy method is simply an insult to people's intelligence.

Did someone really hit the jackpot?

Yan Wan couldn't understand it.

After she and Su Heng cleaned up the battlefield, they immediately walked back to the underground shelter.

Immediately afterwards, Su Heng asked Xiao Hei No. 2 to hold the airdrop box captured for the first time and patrolled around the airdrop coordinates.

When Yan Wan asked Su Heng why she did this, Su Heng gave her the simplest answer.

"Remove potential threats and obstacles."

At that time, Yan Wan felt that the idea of ​​putting venom grenades in an empty box, no one would be able to hit the skill.

the reason is simple.

The labor robots are running around with airdrops on their hands. Isn't this a trap?

A line was written in large and bold fonts: "This is a trap, jump in quickly!"

Anyone with a little brain will be hesitant and cautious.

She wouldn't act so recklessly anyway.

"You don't understand that."

"Since these people dare not participate in the airdrop competition, it is obvious that the materials, manpower, and technology are all below the average level."

"Otherwise, how could the future be handed over to an ordinary road?"

"The method is to be mentally retarded, but there is a sentence I don't know if you have heard it."

Yan Wan wrinkled her beautiful eyes: "Which sentence?"

"You don't choose food when you're hungry, and you don't choose clothes when you're cold."

"Even if you don't eat poison gas, people who take this road will not live long."

Su Heng gave Xiao Hei No. 2 a return instruction, and then began to count the consumption and harvest.

In this battle, the most consumed is the special food, followed by 3 explosive arrows.

The power consumption is negligible.

A flare gun was harvested on the battlefield, including 2 flares, 1 incendiary bomb, and 1 heavy crossbow.

"Aren't you going to open the airdrop?"

"Dismantle, dismantle now!"

Open the drop box.

[Players complete the task without injury, additionally get: 1000 Doomsday Honor]

[Congratulations on getting a chance to draw a lottery, do you want to start the lottery? 】

When Su Heng was completely unprepared, the task completion prompt suddenly popped up.

He glanced at Yan Wan and found that she didn't notice anything unusual.

Fortunately, other people couldn't hear Goldfinger's reminder sound.

smoke!

【Raffle draw, please wait...】

【Congratulations for getting: Induction Cooker*1】

"I'm going, it's **** again."

Su Heng looked forward with anticipation, but unexpectedly pulled out an induction cooker, and blurted out the word "garbage".

Yan Wan picked up the design and glanced at it.

"This boiler can burn coal to generate electricity."

"There are also 10 square meters of solar panels and an unplaced safe house."

"Is this still rubbish?"

Yan Wan twitched the corner of her mouth.

In her opinion, this reward is not bad, after all, it doesn't cost much, some special food and 2 explosive arrows.

Swap these two things for the items in the airdrop box, it's worth it!

"Ah, no no no, I mean some things are garbage." Su Heng explained casually.

Fortunately, Yan Wan didn't take it to heart.

"sleep early."

After Su Heng gave an order, he returned to the underground shelter and organized it in detail.

The biggest gain this time should be the design of the power station boiler, the doomsday solar panel, and 5m?? of disaster-resistant soil.

not bad.

In particular, this power plant boiler can expand diversified power generation methods and realize thermal power generation.

But at the same time, it also brings a problem.

That is, the base's demand for energy will expand.

Although the exchange of goods can be maintained, mining veins is the most cost-effective way.

"I currently have enough resources on hand."

"The next step... is definitely upgrading the reinforced concrete shelter."

"Not only can it expand the population, but it can also improve technology and prepare for the next round of disasters."

Every time Su Heng upgrades the shelter after the disaster is over, before anyone else.

This time, no exception.

[Stone Shelter] has been upgraded to [Reinforced Concrete Shelter]

[Required materials: 0/180 steel plate, 0/90 stone, 84/150 sand, 277000/400000 water]

[Required Doomsday Honor: 1080/16000]

"Early rise early to enjoy, and late rise has no discount."

"Anyway, sooner or later, it will rise, so it's better to be neat."

Su Heng put 400L of pure water!

Since Su Heng was released, he has never done so much.

Upgrading to a concrete shelter should be the biggest resource he spent.

Su Heng used up the number of times the food processor was used today, and he upgraded it by more than 200 liters, which was just enough.

As for other materials, Yin Yanyan mailed him a lot of sand a few days ago. Steel plates and stones are very easy to sweep.

After gathering the materials, Su Heng let out a sigh of relief: "Hu~"

"Confirm upgrade!"

Rumble.

There was another loud noise from the shelter, and there was a slight tremor under his feet. Su Heng clearly felt a sinking elevator.

【update completed】

【Su Heng's Underground Refuge】

Space: 150㎡

Structural strength: 98%

Integrity: 99%

Facilities: wooden table, wooden chair, wardrobe, kang, coal stove.

Disaster Resilience: Excellent +

【You can now recruit more population units】

【Recruitment (to be recruited)】

[According to the assessment of the safe house level, you can now recruit 5/9 units of the population]

After Su Heng clicked it, he found that the original population of 5 units had expanded to 9!

The working robot that was shot by an arrow on the battlefield has been repaired by Xiao Hei.

Since the other party was in the state of [No Owner], Su Heng incorporated it as Xiao Hei No. 4.

In the recruitment column, a new unit card was unlocked for Su Heng.

【Heavy Battle Robot】

[Level: lv.8]

【Type: Mechanical Bionic】

【Function: Combat】

[Evaluation: An upgradeable combat robot from the future, the first heavy-duty long-range combat unit you recruited, with first-class reaction and aiming capabilities, it is the best choice for large-scale battles. 】

[Materials required for recruitment: 16/50 high-grade iron block, 6/50 high-grade steel plate, 6/100 high-grade aluminum block, 0/1 explosion-proof glass, 6/10 high-grade copper block, 1/1 high-grade nylon]

[Doomsday honor points required for recruitment: 1080/3000]

This was the most demanding recruitment Su Heng had ever seen.

All are high-grade materials, and the amount is particularly huge.

The requirement for high-grade aluminum blocks has reached 100!

Su Heng was shocked.

good guy.

With so much material, how fierce is this?

After Xiaohei 4 was incorporated, Su Heng's population was 6/9.

And this heavy combat robot, the required population is 3, just enough to recruit.

Su Heng opened the exchange again.

It took about ten minutes to collect the materials.

"Confirm recruitment!"

【Recruitment completed】

Su Heng's current population reached the upper limit, and the card turned grey-black again, indicating that he could not continue recruiting.

After scanning the golden code, a heavy fighting robot with a height of 2 meters 5 appeared in the underground shelter.

It is 30 cm taller than Big Blue, but about the same size.

The only difference is that it is a heavy armored unit, and the materials and structure settings used are stronger.

Heavy armor is more resistant to beating than light armor, that's for sure.

The factory comes with two [Punisher 12K Grenade Launchers], one for the left and right manipulators.

1 grenade launcher can fire 2 grenades at a time.

The factory is only equipped with one magazine, that is to say, Su Heng has to solve its subsequent ammunition problems.

"I still use a shotgun!"

"Has my little brother used a grenade gun?"

[It is detected that player Su Heng's shelter level ranks among the top in the world, and the [Technology Building] function is now enabled for you]

[Note: At this stage, the [Technology Building] function is limited to players invited by the system]

"Technical buildings?"

Before Su Heng started to think about his next strategic move, the system suddenly popped up a prompt.

Since it was placed, the [Technology Building] column has always been gray-black.

Several times, Su Heng wanted to see what was inside, but found that he couldn't even open it.

Now he is actively inviting him to open it?

"Upgrading concrete shelters with so many benefits?"

"If I knew earlier, I would be crazy about technology!"

To be honest, Su Heng's current technology is not slow.

He already had 4 of them when others were selling iron just to recruit 1 labor robot.

And there are 2 different types of fighting robots.

In the field of science and technology, Su Heng should have been ahead of everyone.

"Hurry up and see what mysterious things are in here."

【Doomsday Engineering Station】

[Can be constructed by iron armored labor robots]

[After completing the construction, you can provide construction and upgrade solutions for your buildings and combat units]

[Required materials: 0/100 high-grade aluminum block, 0/100 high-grade steel plate, 0/100 high-grade iron block]

[Required Doomsday Honor: 1080/4500]

Su Heng quickly exchanged the supplies for enough materials, and went outside to find a hidden place.

"Xiao Hei, Xiao Hei No. 2, Xiao Hei No. 3, Xiao Hei No. 4, all come here!"

Su Heng gave them manufacturing instructions.

The manufacturing process that originally took several hours, four labor robots started work together, and the efficiency increased exponentially.

The construction was completed in just 10 minutes.

This is a squat building.

Regardless of the appearance, Su Heng just wanted to know what it was for.

"It seems that nothing has changed!"

Su Heng fumbled around, and finally found a difference in the weapons and equipment of the two combat robots.

Ammo crafting for heavy combat robots requires less saltpeter.

Big Blue's weapons can also be upgraded with materials!

[Light Armored Combat Robot]

[Explosion Shield (Equipped)]

[C-18 assault rifle (to be equipped)]

[UMU-410 Power Armor (unlocked)]

[Space Enhancer (unlocked)]

[UMC-10 Cooling Unit (unlocked)]

After the construction of the engineering station, the technical equipment of the arms was unlocked two at a time.

Both the blast shield and the C-18 assault rifle can be equipped.

Before because of insufficient technology, these options were all black.

Su Heng picked up an explosion-proof shield in the dungeon and gave it to Da Lan to equip it directly.

If it can be equipped with a C-18 assault rifle, it can completely change the way it fights.

From a melee arm, upgrade to a shooter arm!

[C-18 Assault Rifle]

[Required material: 0/100 high-grade aluminum block]

[Required Doomsday Honor: 1080/200]

Su Heng chose to upgrade with Doomsday Honor Points. UU reading www. uukanshu.com

"Confirm upgrade!"

The epee in Da Lan's hand was scanned with golden light and upgraded to a jet-black assault rifle, which looked very mighty and domineering.

After the upgrade, it comes with a shuttle of 8mm hollow-point bullets with a capacity of 30 rounds.

Subsequent ammunition supplies are still replenished by saltpeter.

The hollow-point bullets can also be replaced with: electromagnetic bullets, spiked bullets, depleted uranium bullets, incendiary bullets, and other types of bullets.

Depending on the type of bullet, the amount and material of saltpeter required will vary.

Originally, this airdrop competition improved Suheng's power supply, obtained a third power generation method, and also expanded the land area and the diversity of plants.

But after a series of upgrades, Su Heng was so excited that his mind was a little confused, and he had to make a good calculation.

"Let me analyze it carefully."
