Global Catastrophe: I Am Cultivating Immortals in the Refuge

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

　　 "300 points!"

　　 He nodded, and then said:

　　 "Call up the system mall."

　　 As soon as the voice fell, in front of Chen Nuo's eyes, the mall panel appeared.

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

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

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

　　 It’s just that after looking around, it doesn’t seem to satisfy Chen Nuo.

　　 "Perhaps, all the things I need are in the scientific research base?" He suddenly thought of something.

　　 After all, the scientific research base can make weapons and other technologies, and 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 called up the shelter equipment template.

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

　　 The power station needs one hundred upgrade points to upgrade. After the upgrade, the area doubles, and it can supply 1,000 watts of electricity per hour!

　　 The scientific research base needs 100 upgrade points to upgrade. After the upgrade, the area remains the same. New items that can be crafted: Barrett cannons, missile cannons, missiles, 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:

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

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

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

　　 entered the scientific research base.

　　 There are not many changes in the scientific research base at this time, the only change may be the few robotic arms.

　　 "Research." He shouted.

"I'm here!"

　　 "Call up all the item panels you can make." Chen Nuodang even ordered.

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

　　Barrett cannon, it takes 1 catty of gold, ten catties of iron, 1 catty of masonry, 1 catty of copper, or an energy spar to make!

　　Barrett bullets, 0.1 jin of gold is required to make, or one energy spar can be exchanged for ten bullets!

　　 Missile barrel, it takes 2 catties of copper, 2 catties of gold, or an energy spar to make!

　　 missile, it takes 1 catty of gold or an energy spar to make!

　　Protective clothing, it takes 1 catty of copper, one catty of silk, one catty of gold, one catty of masonry, or five energy spars to make!

　　……

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

　　 "It seems that the materials I currently have are not too sufficient..." muttered, and he began to check the capabilities of the new items.

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

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

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

　　 After all, five is a fifty-point upgrade point.

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

　　 After all, that's a fifty-point upgrade point.

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

　　 This let Chen Nuo know that he still has too few materials.

　　 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 about this, he asked.

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

　　 "Upgrade!" This time, Chen Nuo hesitated a little before finally uttering these two words.

　　 After all, he has only two hundred points left to upgrade.

　　 "I hope the upgraded scientific research base has what I need." As I thought to myself, in my mind, the system prompt sounded:

　　 "Ding, you spend two hundred 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's prompt sound appeared, the space in the entire scientific research base instantly expanded nearly doubled!

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

　　 There is no change in the center console.

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

　　 "Yes." As the scientific research responded, a 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 masonry, and an energy spar!

　　 cannon, you need ten catties of copper, ten catties of iron, ten catties of gold, or five energy spars!

　　……

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

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

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

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

　　 "Cannonball pistol?!" He was puzzled.

　　 How does the shell and the pistol have something to do with each other?

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

"It is an upgraded pistol that can be loaded with miniature shells after the Desert Eagle. In short, it is a pistol that shoots out not bullets, but cannonballs!" The scientific research explained clearly. .

　　 Chen Nuo fell silent after hearing this.

　　 A pistol that can carry miniature shells?

　　 In other words, this pistol can fire shells?

　　 Thinking like this, Chen Nuo became interested, and Dang Even asked:

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

　　 "Yes, do you want to upgrade?"

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

　　 "Two days!"

　　 The scientific research answer is very decisive.

　　 Chen Nuo pondered a little, and then asked:

　　 "Are there any model pictures of cannonball pistols and power data?"

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

　　 Above, there is a desert eagle very similar, but the whole body is pitch black, and the magazine position has become longer and enlarged.

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

　　 Cannonball pistol, a pistol equipped with a one-centimeter miniature cannonball. It has a fast firing speed and can cause damage with a radius of ten centimeters.

　　 Looking at these materials, Chen Nuo understood.

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

　　 It’s just that it is very powerful to create a radius of about ten centimeters.

　　 is worth starting.

　　 Thinking, Chen Nuodang said:

　　 "Scientific research, upgrade me."

　　 said, he took out the desert eagle that he had been carrying and placed it on the center console.

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