Global Cataclysm: Start building a dungeon

The more anxious this person is, the more likely he is to be in danger!

Therefore, Ye Liangren is not in a hurry.

Wait until you are sure everything is safe! "Ding!The production of the desert eagle pistol and fifty bullets is completed! 』

At this time, the system prompt appears.

Ye Liangren's eyes lit up, and the next moment he saw a handful of Desert Eagle and fifty rounds of bullets, which had been processed.

Picked up the pistol and felt it.

A bit heavy, but, okay!

Originally, he wanted to practice again.

But there is no place for shooting here, and it would be too wasteful to open up a separate shooting room, and in itself, as long as the gun is fired, there will be a deterrent effect.

Moreover, that factory is very remote. He watched it on the surveillance screen for a long time, so it shouldn't be too dangerous!

However, Ye Liangren thought for a while, and spent another 220 survival points to produce both the bulletproof vest and the bulletproof helmet.

At this time, the system prompt sound appears again. "Ding!You have successfully produced weapons and defensive equipment. Although you cannot withstand the coming natural disasters, you have a lot of deterrent power in the face of man-made disasters, which makes your going out more secure!Reward: Survival Points +90. 』『 Remaining survival points: 5600. 』

"Well, as expected, I can also get rewards. Although there are not many, the survival points I spent this time are not many!"

A bright smile appeared on the corner of Ye Liangren's mouth.

Put on your body armor, put on your bulletproof helmet, and put away your pistol and bullets.

Then, he took out ten catties of rice from the storage room, got up, went upstairs, and walked outside the shelter!

Trade Pure Iron!

Just walked out the gate.

Ye Liangren suddenly felt so hot!

You know, it's November!

How can it be so hot?

At least twenty or thirty degrees!

When Ye Liangren raised his head, his pupils suddenly shrank!

"That is?!"

God, it's bright!

Not a cloud!

Moreover, there is a colorful light!

"Sun spots?!!!"

Ye Liangren hurried back to the house and hurried into the underground shelter!

"Looking at the situation, the atmosphere may have been completely corroded by the eruption of the sun's flare, so now, you must not go out!"

Compared with trading pure iron, your own safety is more important!

Without the protection of the atmosphere, ultraviolet rays are enough to kill all the cells in the human body!

Ye Liangren looked solemnly.

too fast!

The atmosphere is being corroded too fast!

And, in the future, more people will notice the importance of the shelter!

It is very possible that other people may also trade the [-] kilograms of pure iron!

Ye Liangren's eyes froze.

Hastily came to the military scientific research base.

Look at the information above.

"Military Research Base"

"Level: 1. 』

"Upgradeable! 』

"Upgrade direction: level 2! 』

『Scientific research direction: artificial intelligence (1000), expansion of scientific research direction (1000), scientific research level (1000). 』

"Remaining survival points: 5600. 』

Ye Liangren gritted his teeth and said:

"Upgrade artificial intelligence and expand scientific research direction!" "Ding!You spent a total of 2000 survival points to upgrade the scientific research base, and the upgrade was successful! 』

"Super Research Base"

"Level: 2. 』

"Upgradeable! 』

"Upgrade direction: level 3! 』

"Scientific research direction: scientific research level (1000). 』

"Remaining survival points: 3600. 』

The system prompts.

The research base has changed again.

This time, it's bigger.

A single scientific research base has a size of at least 800 square meters!

At the same time, there are many more magical things.

At this time, the system prompt sound appears again. "Ding!You have upgraded the scientific research base, the super research base, which can truly produce artificial intelligence, so that even if you are alone, you are equivalent to an army!Technology is always the primary productive force!Especially at the end of the day!Reward: Survival Points +1600. 』『 Remaining survival points: 5200. 』

Ye Liangren breathed a sigh of relief!

"Fortunately, my choice is not wrong, this time the reward is enough survival points!"

After obtaining survival points several times in a row, Ye Liangren also faintly found the law.

The more you can guarantee your survival in the doomsday, the more rewards you will get for survival points!

This time, 1600 survival points were directly rewarded, which shows that upgrading the scientific research base to a super research base is definitely the most important event in the apocalypse!

Ye Liangren's eyes fell on the production list of the super research base.

In addition to the already known weapons, many other things have been added at this moment.

"Current production series:

Battle Robots: Level 2!Required materials: 5kg of pure iron, 2kg of titanium alloy, 1 energy stone!

Handling Robot: Level 2!Required materials: 5kg of pure iron, 2kg of titanium alloy, 1 energy stone!

Combat Drone: Level 2!The required materials are 3kg of pure iron, 1kg of titanium alloy, and 1 energy stone!

Unlocked weapons:

Level 3: Nuclear drones, combat robots (second generation), handling robots (second generation)...etc. 』

『Note: Robots below level 5 do not have artificial intelligence and can only accept some simple basic commands! 』

"Currently available defensive equipment series:

Iron Armor: Level 2!Required materials: 10kg of pure iron, 2kg of aluminum alloy, 1kg of titanium alloy, 1 energy stone!

Exoskeleton Armor: Level 2!Required materials: 5kg of pure iron, 1kg of aluminum alloy, 1kg of titanium alloy, 1 energy stone!

Unlocked equipment:

Level 3: Iron armor (second generation), exoskeleton armor (second generation)...etc. 』

……

Chapter 6 Trap

"No wonder, upgrading the scientific research base can reward me with 1600 survival points at once!"

"The robots that can be produced now can completely replace me to carry the pure iron, titanium alloy, aluminum alloy... and other materials from the outside world!"

"In this way, even if the sun's flare breaks out, I can still complete the transaction!"

"And, without me going out in person, my safety can be protected to the greatest extent!"

Ye Liangren looked at the super research base and smiled brightly.

"However, if you want to make these robots, do you have to upgrade the exchange system to level two?"

Ye Liangren took a closer look at the materials needed to make these robots, frowned, and his eyes fell on the exchange system.

"Exchange System"

"Level: 1. 』

"Upgradeable! 』

"Upgrade direction: level 2!Survival points needed: 1000. 』『 Remaining survival points: 5200. 』

"It takes a thousand survival points to upgrade!"

Ye Liangren felt a little pained.

Now, he is more and more aware of the importance of survival!

However, compared to the survival point, the value of these robots at this moment is higher!

Ye Liangren gritted his teeth and said:

"System, upgrade the exchange system!"

"Ding!The exchange system has been upgraded successfully! 』

"Exchange System"

"Level: 2. 』

"Upgradeable! 』

"Upgrade direction: level 3!Survival points needed: 2000. 』

"Current exchangeable list:

Pure iron 1kg: 10 survival points!

Titanium alloy 1kg: 100 survival points!

Aluminum alloy 1kg: 200 survival points!

1 energy stone: 500 survival points!

Unlocked list:

Level 3: Nanomaterials, superalloys T1-V...etc. 』『 Remaining survival points: 4200. 』

"If you upgrade again, you will need 2000 survival points!"

Ye Liangren felt even more painful, and then exhaled softly.

"However, the materials that can be exchanged for the second level should be able to be used for a long time! After all, even if the super research base is level three, there are no nano products!"

Ye Liangren studied it for a while, and then spoke again.

"System, exchange for 4 energy stones! 8kg titanium alloy! 20kg pure iron!"『Ding!To exchange 4 energy stones, 8kg titanium alloy, and 20kg pure iron, it will cost 3000 survival points in total. Are you sure you want to confirm the exchange? 』

"Yes!"

Ye Liangren gritted his teeth and nodded.

"Ding!The exchange was successful! 』『 Remaining survival points: 1200. 』

Follow the prompts.
