"System, how many upgrade points are there in my current upgrade points?" Chen Nuo asked.

“300 points!”

He nodded and then said:

"Click out the system mall."

As soon as he finished speaking, the mall panel appeared in front of Chen Nuo's eyes.

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

Because, after learning, he knew that his current realm could not allow him to cast any spells, even if he could cast them, his power would be insignificant.

So, he plans to see if there are any equipment he needs in technology.

However, after looking around, there seemed to be no equipment that satisfies Chen Nuo.

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

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

So he took the elevator to the scientific research base on the third floor.

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

The water source station needs fifty points to upgrade, and the area after upgrading will double, and it can supply 0.1 tons of water per hour!

The power station requires 100 upgrade points, and the area after upgrading is doubled, and it can supply 1,000 watts of electricity per hour!

The scientific research base requires 100 upgrade points, and the area remains unchanged after the upgrade. New items that can be crafted: Barret cannons, missile cannons, missiles, protective clothing...

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

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

"The system consumes 100 upgrade points to upgrade the scientific research base."

"Ding, you have consumed 100 points to upgrade the scientific research base, and the area of ​​the scientific research base remains unchanged."

As soon as Chen Nuo finished speaking, he arrived at the third floor.

Enter the scientific research base.

There was not much change in the scientific research base at this time, and the only change might be those robotic arms.

"Scientific research." He shouted.

"I am here!"

"Click out all the items you can make." Chen Nuo immediately ordered.

As soon as he finished speaking, countless items appeared on the center console in front of him instantly.

Barrett cannons, making requires 1 kilogram of gold, ten kilograms of iron, 1 kilogram of bricks, 1 kilogram of copper, or an energy crystal!

Barrett bullets, it takes 0.1 kilogram of gold to make, or exchange one energy crystal for ten bullets!

To make missile barrels, 2 kilograms of copper, 2 kilograms of gold, or an energy crystal!

To make missiles, 1 kilogram of gold or an energy crystal is required!

Protective clothing requires 1 kilogram of copper, one kilogram of silk, one kilogram of gold, one kilogram of bricks, or five energy crystals!

...

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

"It seems that the materials I have are not enough now..." murmured, and he began to check the ability of new items.

Among them, the protective clothing surprised Chen Nuo.

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

Therefore, it is worthy of the value of five energy crystals.

After all, five can be upgraded only fifty points.

Of course, Chen Nuo did not buy it directly, but pondered.

After all, that's fifty upgrade points.

However, what made Chen Nuo hesitate was because there was an additional "silk" in the materials needed for this protective suit.

This made Chen Nuo know that he still had too few materials.

In addition, what the scientific research base currently has is not what you need.

"System, how many upgrade points are needed to upgrade the scientific research base again?" 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 has two hundred points left to upgrade.

"I hope there is what I need in the upgraded scientific research base." As I thought to myself, a system prompt sound appeared in my mind:

"Ding, you spend 200 upgrade points to upgrade the scientific research base! The area of ​​the scientific research base has been expanded from 92 square meters to 150 square meters!"

The moment the system prompt sound appeared, the space in the entire scientific research base expanded by nearly twice in an instant!

Among them, the original five robot arms were also changed to ten, and several production stations were added.

There is no change in the center console.

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

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

Above the light curtain are several new technologies.

Mechanical armor requires ten kilograms of copper, ten kilograms of iron, ten kilograms of gold, ten kilograms of silk, ten kilograms of bricks and stones, and an energy crystal!

Cannons require ten kilograms of copper, ten kilograms of iron, ten kilograms 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 had purchased before.

"This is..." Chen Nuo's pupils dilated and he couldn't help but reach out and click.

"It can consume one pound of copper, and one pound of iron upgrade the Desert Eagle to a shell pistol!"

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

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

Why do shells and pistols have something to do with each other?

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

"It is a pistol that can be equipped with micro shells after the Desert Eagle upgrade. In short, it is a pistol that is not a bullet, but a shell!" The scientific research explained it very clearly.

Upon hearing this, Chen Nuo was silent.

A pistol that can carry micro shells?

In other words, can this kind of pistol fire shells?

Thinking of this, Chen Nuo became interested and immediately asked:

"System, are there enough materials in the material room now?"

“Yes, is it upgraded?”

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

"Two days!"

The scientific research answers are very decisive.

Chen Nuo pondered for a while and then asked:

"Are there any model pictures of the shell pistol and its power information?"

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

Above, it is a very similar to the Desert Eagle, but its whole body is pitch black, and the magazine position has become longer and expanded.

Next to the picture are various information about the shell and pistol:

The shell pistol, a pistol with one centimeter of micro shells, fires very fast and can cause damage with a radius of ten centimeters.

Looking at these information, Chen Nuo understood.

This is a pistol that can fire shells, but its power is only one thousandth of that of the shells.

However, it can cause a radius of about ten centimeters, which is very good.

Worth buying.

Thinking of this, Chen Nuo immediately said:

"Scientific research, upgrade me."

As he said that, he took out the desert eagle he had been carrying with him and placed it on the center console.
Chapter completed!
