Global Catastrophe: I Am Cultivating Immortals in the Refuge

"Seven hundred upgrade points, one hundred points away from upgrading the shelter level, it seems that we can only upgrade the scientific research base."

Chen Nuo sat on the sofa and pondered for a while, and finally called up the system upgrade equipment panel and chose to upgrade the scientific research base.

"Ding, you spend 400 points to upgrade the scientific research base, but the area of ​​the scientific research base remains the same!"

When this sentence from the system appeared, Chen Nuo had already taken the elevator to the third floor.

"Research, call out all the things you can make now." Chen Nuo directly ordered.

In seven days, the second wave of disasters will come.

Tens of thousands of subterranean core beasts will emerge from the holes created by the planetary debris.

At that time, human beings will be reduced to food, and saving their lives has become beyond the luxury of ordinary citizens.

However, Chen Nuo knew that if the current self hid in the refuge, she would definitely be able to survive the second wave of liquidation.

However, it also meant that he missed a large number of upgrade points.

And once he gave up these upgrade points, his refuge could only stay at the current level.

After all, judging from the current situation, the daily upgrade points are no longer enough to upgrade the shelter.

So, he's going to make a weapon!

Make weapons that can kill the beasts at the core of the underground!

While pondering in his heart, he looked at the various technological weapons and other equipment projected on the center console.

...

Gatling: It takes five catties of iron, five catties of copper, and one energy spar to make it!

Grenade: It needs a catty of iron and a catty of copper to make!

Cannon: Fifty catties of iron, fifty catties of copper, and two energy spars are needed to make it!

Tank: One hundred catties of iron, one hundred catties of copper, and ten energy spars are needed to make it!

Cannon shells: One catty of iron and ten catties of gunpowder are needed to make it!

Tank shells: Five catties of iron, five catties of copper, and twenty catties of gunpowder are needed to make them!

...

At this time, many powerful weapons have been added to the weapons that can be produced by scientific research.

Examples: Tank, Cannon, Gatling.

These are powerful weapons against the underground core beasts!

At least, the power of the tank is still very huge, as long as you don't encounter thick-skinned monsters, it should be easy to deal with.

However, these required things...

This made Chen Nuo frowned, but he made up his mind.

Within seven days, a tank, or cannon, must be made.

At least, this way, you can kill monsters to get upgrade points when the time comes.

While thinking this way, he also discovered the value of "energy spar".

"System, I want to exchange one hundred upgrade points for ten energy crystals!" He ordered immediately.

This is necessary, at least, if you want to make a tank at present, energy spar is necessary.

"Ding, you spent one hundred upgrade points to buy ten energy spars! They are now stored in the material warehouse of the scientific research base!"

Hearing this, Chen Nuo nodded, and then continued to look at the technologies currently available in the scientific research base.

Among them, there are still some things that interest him.

For example, one of them is called Mecha Armor, which is similar to the armor of the armored warrior, but it is more bulky, just like the first generation of Iron Man.

However, although it is bulky, it is still necessary when one's own strength can fight without any weapons.

After all, it can make others not recognize him.

Otherwise, if it is recognized, God knows what crazy actions humans will do?

Therefore, this naturally entered Chen Nuo's must-order list in the future.

Secondly, there are other lethal weapons that also made Chen Nuo's eyes shine.

And what excited Chen Nuo the most was because he discovered that after the scientific research base was upgraded, the unmanned reconnaissance aircraft and unmanned fighter jets he bought earlier can be upgraded!

Unmanned reconnaissance drone: an energy spar is required to upgrade,

After the upgrade, the size of the unmanned reconnaissance drone is reduced by one tenth, and the control system is upgraded to the route setting mode!

Unmanned Fighter: Upgrading requires a catty of iron, 0.1 catty of pure gold, and an energy spar. After upgrading, a mechanism for firing shells is added, and the control mechanism is upgraded to an automatic attack mode!

Seeing this, Chen Nuo's pupils couldn't help dilating.

"0.1 jin of pure gold..." However, while excited, she was also a little silent.

"How much gold is needed to refine 0.1 jin of pure gold?" he asked.

"It takes one catty of gold to refine 0.1 catty of pure gold!" Chen Nuo nodded at the scientific answer.

"How many materials are left in the material warehouse? List them out for me." Chen Nuo ordered.

As soon as the voice fell, the light curtain on the center console changed the screen.

"There are still 5.5 catties of copper, 10.6 catties of iron, 2.6 catties of gold, and 1.38 catties of masonry!"

At the same time, scientific research also responded accordingly.

Chen Nuo nodded and pondered.

"It seems that I have to go out and get some resources tomorrow." While pondering, he thought of something, raised his head and ordered:

"By the way, make me another Desert Eagle."

Because you want to go out, you must have self-defense weapons, and shell pistols are obviously not the first choice.

After all, after going out, what he faced were people, not monsters.

As soon as the voice fell, the robotic arm in the scientific research base began to work.

"There are 200 upgrade points left, what are you going to use them for?" Chen Nuo was thinking as he walked towards the first floor.

However, after thinking about it, he decided to go to bed first and make plans tomorrow.

At night, he slept soundly.

But the people outside did not have his mentality.

Moreover, if people outside know that he has lived so "easy" and "cool" for the past seven days, they are afraid that they will commit suicide.

...

At this time, it was located in an underground shelter in the city of Huaxia Emperor.

Here is the refuge of the government headquarters.

Because the command post on the ground disappeared, they moved here.

Together, of course, there are people from the space agency.

After all, they have to keep an eye out for planetary debris.

At this time, when the vibration and roar disappeared, everyone was a little excited and puzzled.

Until, the people from the space agency sent the news.

Afterwards, everyone breathed a sigh of relief.

"This sudden disaster has finally disappeared!"

"Fuck! Liberated!"

"The disaster... is over!"

"We were rescued!"

"Dog day! Drink all night tonight! My treat!"

The entire headquarters cheered.

Some people even burst into tears.

There are also people who lost their loved ones in the disaster, so they are silent in an extremely uncomfortable feeling.

You know, during the past seven days, everyone was worried.

Now, the feeling of relief in their hearts can even be imagined.

But soon, everyone fell silent.

They got to work.

They want to reconnect the entire Huaxia circuit, and then transmit the news to all places in China.

Let people know that the disaster... is over!

At the same time, they also began to quickly restore the system that was paralyzed throughout China due to the disaster.

After all, the loss this time was extremely heavy!
