Dingdong!

Suddenly, just as Chen Nuo was watching the excitement, the cell phone on the desk issued a prompt sound.

He opened his phone and looked at the WeChat contact person who said "Dog smashed" and Chen Nuo clicked on a voice he sent.

"Old Chen, have you read the news yesterday that said planetary fragments were about to come to Earth?"

"I know, what's wrong?" Chen Nuo typed a line of words.

"Damn it! Are you so calm? But that's right. With your value, you don't need to worry about the official shelter not letting you in."

The other party still sends a voice message.

"Yes, I'm already in the official shelter." Chen Nuo thought for a while and said this.

The purpose is to avoid him coming here, or ask for his own help and take him into a shelter.

After all, Chen Nuo doesn't want to be so troublesome, or rather, he is known to his refuge by too many people.

You must know that in the face of danger, the most important thing to test is human nature.

Dingdong!

"Damn! You're fast enough! What...if you can, please leave a place for your brother!"

"I took a plane to the official shelter in the capital after seeing the news yesterday. After all, the shelter in the capital is definitely better than the shelter in Zhennan City."

After sending it out, Chen Nuo typed again:

"But there are too many people here, and I can only come in..."

He didn't say it clearly, but everyone knew what he meant.

"Hell, your kid is so stupid! No wonder he can be worth tens of millions overnight!" The other party took a breath and couldn't help but sigh.

Chen Nuo raised his lips, smiled slightly, and then closed the chat with him.

Then, he saw many group chats at the peak.

Obviously, because the news was confirmed, they had a topic.

Of course, Chen Nuo knew that this was just the beginning, and in the next few days, people would be in chaos.

After all, no matter how the official shelter is, it cannot accommodate so many people.

However, after thinking about it, Chen Nuo suddenly thought of a news about the United States I saw yesterday, which made him open Baidu and start searching for related news.

However, except for the two news yesterday, there is no more news in the United States.

Although it is not clear whether the United States has really caught monsters similar to the core beasts underground, they have a style that has remained unchanged for thousands of years.

Shaking his head, Chen Nuo felt relieved and immediately ordered the system to call out the system mall.

When he clicked on the technology category, he looked through it and one of them was moved by a "scientific research base".

Scientific research base, ten points to upgrade points required for purchase, covering an area of ​​92 square meters, and use the required materials to make scientific and technological weapons: Desert Eagle (requires 0.01 grams of copper, 0.01 grams of iron!), bullets (requires 0.01 grams of copper for one bullet.)…

Looking at the information in front of him, Chen Nuo's pupils couldn't help but widen a little.

"It seems that this so-called scientific research base is the place where weapons are made. No wonder the system once said that hunting monsters can also obtain upgrade points, but this is the reason!" Chen Nuo murmured and clicked on the ellipsis.

Immediately afterwards, the entire light curtain was filled with the names of various technologies and the required materials.

Drone: 10 grams of copper, 10 grams of gold, 10 grams of silver required!

Unmanned fighter: 50 grams of copper, 30 grams of gold, 10 grams of masonry! (You can also use an energy crystal to exchange it!)

...

Many of the previous columns require copper, gold, or other production materials, but they are unmanned fighters that can actually be exchanged for energy crystals.

Therefore, Chen Nuo couldn't help but feel a little confused.

"What is this energy crystal? How can I get it?" He felt that since an energy crystal can replace so many materials, this energy crystal is absolutely extraordinary.

As soon as he finished speaking, the picture in front of him jumped instantly.

In the middle of the light curtain is a small stone with blue light shining all over its body.

The size and appearance of this stone are similar to the crystals in the Avengers.

The following information shows:

You can buy an energy crystal at ten points!

Seeing this scene, Chen Nuo frowned and couldn't help but ponder.

It seems that the reason why this system can run depends entirely on the upgrade point.

In addition, weapons and other things are exactly what I need in the end of the world.

Therefore, this scientific research base must be an indispensable equipment.

Thinking of this, he couldn't help but look at the remaining 120 upgrade points.

"System, I want to buy a scientific research base." Chen Nuo immediately ordered.

"Ding, you have successfully purchased a scientific research base with ten points to upgrade. Please set up a location!"

"Calling out the shelter template." When the system prompt sound appeared, Chen Nuo immediately ordered.

As soon as the words were finished, the template of the entire refuge emerged before his eyes.

Because the scientific research base is large and the area at the beginning is 92 square meters, Chen Nuo installed it directly on the third floor.

This also directly left the third floor without any extra space.

"It seems that the 100 square meters is still too small." Chen Nuo thought of this problem.

"By the way, system, can I upgrade the shelter again and just increase the area of ​​the third floor?" Chen Nuo asked.

"Does the host think the house can be built like this?" However, what surprised Chen Nuo was that the system answered him like this.

"After the host chooses to increase the area of ​​the first layer, the area of ​​the following layers will double! If the host chooses to build downwards, then it will only build one layer with the same area as the first layer."

Chen Nuo nodded, but the only thing that made him anxious was that whenever he increased the area, he needed to mobilize the room and partition wall on the first floor again.

"The partition walls and rooms in the shelter can be automatically set by the system."

Suddenly, just as Chen Nuo was thinking like this, the system's answer instantly made Chen Nuo's mouth twitch.

"Then you said it earlier?"

"The host didn't ask."

...

When Chen Nuo purchased the scientific research base, he suddenly discovered that the scientific research base needed electricity to operate.

So, he turned on the power station upgrade details from the shelter template:

The upgrade requires fifty upgrade points. After the upgrade, the power station level is upgraded to level 2, and 100 watts of electricity can be supplied per hour!

"I chose to upgrade the power station!" After reading these information, Chen Nuo immediately ordered.

Although it takes fifty upgrade points to upgrade one level, this is what he needs, so this upgrade point doesn't matter.

"Ding, the upgrade was successful!"

"Host: Chen Nuo."

“Sanctuary: Level 3 (upgradeable!)”

"Sanctuary Equipment: Fingerprint unlocking aluminum alloy doors, power stations, water source stations, scientific research bases!"

“The remaining upgrade points: 60 points!”

In front of me, because of the upgrade, Chen Nuo's attribute panel was once again pushed by the system.
Chapter completed!
