Global Catastrophe: I Am Cultivating Immortals in the Refuge

"System, how many upgrade points do I have?" Chen Nuo asked.

"300 points!"

He nodded, and continued:

"Call out the system mall."

As soon as the words fell, the mall panel appeared before Chen Nuo's eyes.

However, this time, Chen Nuo did not choose to cultivate immortals.

Because, after learning, he knows that his current state does not allow him to cast any spells, even if he can cast them, the power is negligible.

So, he plans to see if there is any equipment he needs in the technology category.

However, after looking around, it seems that there is no equipment that satisfies Chen Nuo.

"Maybe, everything I need is in the scientific research base?" He suddenly thought of something.

After all, technology such as weapons can be produced in the scientific research base, and what I lack now is that kind of thing.

Ever since, he took the elevator to the scientific research base on the third floor.

At the same time, he called up the shelter equipment template.

The water source station needs 50 upgrade points to upgrade. After the upgrade, the area doubles and it can supply 0.1 tons of water per hour!

The power station needs 100 upgrade points to upgrade. After the upgrade, the area doubles and it can supply 1000 watts of electricity per hour!

The scientific research base requires 100 upgrade points to upgrade. After the upgrade, the area remains the same, and new craftable items are added: Barrett Cannon, Missile Cannon, Missile, Protective Clothing...

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

"It seems that this scientific research base has contracted a lot of things." The corner of his mouth raised, and then he ordered:

"System, consume 100 upgrade points to upgrade the scientific research base."

"Ding, you spent one hundred upgrade points to upgrade the scientific research base, and the area of ​​the scientific research base remains unchanged."

As soon as the words fell, Chen Nuo came to the third floor.

Enter the research base.

At this time, the scientific research base has not changed much, and the only change may be the few mechanical arms.

"Research." He called out.

"I am here!"

"Call out all the item panels that you can make." Chen Nuodang immediately ordered.

As soon as the voice fell, countless items appeared on the center console in front of him in an instant.

Barrett Cannon requires 1 catty of gold, 10 catties of iron, 1 catty of masonry, 1 catty of copper, or one energy spar to make!

Barrett bullets need 0.1 jin of gold to make, or exchange one energy spar for ten bullets!

The missile barrel needs 2 catties of copper, 2 catties of gold, or an energy spar to make!

Missiles need 1 catty of gold or an energy spar to make!

Protective clothing requires 1 jin of copper, 1 jin of silk, 1 jin of gold, 1 jin of masonry, or 5 energy spars!

...

Looking at the newly added items in front of him, Chen Nuo's face couldn't help but darken a little.

"It seems that the materials I have now are not enough..." muttering, he began to check the abilities of the newly added items.

Among them, nothing surprised Chen Nuo more than the protective clothing.

Because this thing is bulletproof, internal oxygen, and explosion-proof.

Therefore, it is also worthy of the value of five energy spars.

After all, five is 50 upgrade points.

Of course, Chen Nuoke didn't buy directly, but pondered.

After all, that's fifty upgrade points.

However, what made Chen Nuo hesitate was because there was an extra "silk" in the material required for the protective clothing.

This let Chen Nuo know that the materials he had were still too little.

In addition, as far as the current scientific research base has, it is not what I need.

"System, how many upgrade points are needed to upgrade the scientific research base again?" Thinking like this, he asked.

"Two hundred points!" The system's answer was very decisive.

"Upgrade!" This time,

Chen Nuo hesitated for a while, and finally said these two words.

After all, he only had 200 upgrade points left.

"I hope the upgraded scientific research base has what I need." While thinking to myself, a system notification sounded in my mind:

"Ding, you spend two hundred upgrade points to upgrade the scientific research base! The area of ​​the scientific research base has expanded from 92 square meters to 150 square meters!"

The moment the system's notification sound appeared, the space in the entire scientific research base nearly doubled in an instant!

Among them, the original five mechanical arms were also changed to ten, and at the same time, several production tables were added.

The center console remains unchanged.

"Scientific research, call out the new technology you added after upgrading." Chen Nuo immediately ordered.

"Yes." Following the scientific research reply, the light curtain appeared on the center console again.

Above the light curtain, there are several new technologies.

Mechanical armor requires ten catties of copper, ten catties of iron, ten catties of gold, ten catties of silk, ten catties of bricks, and one energy spar!

Cannon requires ten catties of copper, ten catties of iron, ten catties of gold, or five energy crystals!

...

In addition, what surprised Chen Nuo was that there was a small word "upgrade" on the upper right corner of the Desert Eagle he bought before.

"This is..." Chen Nuo's pupils dilated, and he couldn't help reaching out and clicking.

"One catty of copper and one catty of iron can be used to upgrade the Desert Eagle to a cannonball pistol!"

Looking at the details that popped up, Chen Nuo was stunned.

"Cannonball pistol?!" He was a little puzzled.

How do shells and pistols get involved?

"What is this shell pistol?" Chen Nuo couldn't help asking.

"It is a pistol that can be loaded with miniature shells after the upgrade of the Desert Eagle. In short, it is a pistol that fires shells instead of bullets!" The scientific research explained very clearly.

Hearing this, Chen Nuo fell silent.

A pistol that can load miniature shells?

That is, such a pistol can fire shells?

Thinking of this, Chen Nuo became interested, and Dang even asked:

"System, is there enough material in the material room now?"

"Yes, do you want to upgrade?"

"How long does it take to upgrade?" Chen Nuo subconsciously asked.

"Two days!"

The scientific answer is decisive.

Chen Nuo pondered for a while, then asked:

"Do you have any model pictures and power information of the shell pistol?"

"Yes." As soon as the words fell, a picture appeared on the light curtain in front of him.

Above, is a similar to the Desert Eagle, but the whole body is black, and the clip position has become longer and enlarged.

Next to the picture, there are various information about the shell pistol:

Cannonball Pistol, a pistol equipped with a one-centimeter micro-cannonball, which fires very fast and can cause damage in a radius of ten centimeters.

Looking at these materials, Chen Nuo finally understood.

This is a pistol that can fire cannonballs, but the power is one-thousandth of the cannonballs.

It's just that the power that can cause a radius of about ten centimeters is not bad.

It is worth starting.

Thinking about it, Chen Nuo immediately said:

"Research, upgrade me."

As he said that, he took out the Desert Eagle that he had been carrying all the time and placed it on the center console.

"Okay!" came the voice of scientific research, and then a robotic arm quickly came to the center console and took away the Desert Eagle.
