Global Catastrophe: I Am Cultivating Immortals in the Refuge

2045, January 13, at five o'clock in the morning.

In a black hole caused by planetary debris outside the villa area in Zhennan City.

At this moment, an unmanned reconnaissance plane suddenly flew out of it at an extremely fast speed, followed by three unmanned fighter jets!

Then, I saw that the four little guys did not leave quickly, but stopped not far away, and then turned their heads to look at the black hole.

At the same time, Chen Nuo in the refuge was staring at the computer screen.

Just now, he saw that the four drones were about to fly out of the black hole, but the strange birds still did not stop, so he couldn't help but feel that his actions might draw these monsters out in advance.

So, at this moment, he felt a little nervous...

After all, if it is really drawn out, the world will be in chaos in advance.

At that time, he himself became the culprit.

However, to his relief and surprise, the black hole didn't move at all?

Seeing this, he was stunned.

what happened? !

You know, when you were only 500 meters away from the exit, those strange birds were still chasing after you...

what now...

He was a little confused.

Subconsciously, he controlled the unmanned reconnaissance plane and flew towards the black hole, wanting to find out.

However, when the unmanned reconnaissance plane projected the pitch-black black hole below onto the computer, Chen Nuo fell silent.

This…

At this time, the black hole seemed to have returned to its previous calm, and there were no shadows of those strange birds at all.

This made Chen Nuo stunned, but after a moment of analysis, he was relieved.

Presumably, these strange birds are currently unable to come out of the black hole for some reason.

However, what is the reason?

Of course, when he was puzzled, Chen Nuo couldn't help but breathe a sigh of relief.

After all, just now, he felt that he had almost lured these monsters out ahead of time.

Therefore, at this time, he couldn't help but breathe a sigh of relief.

At the same time, after this experience, Chen Nuo also had a certain understanding of these monsters.

The currently known monsters include strange wolves and strange birds. They are very large, and the speed and attack power of the strange birds are very strong.

This can be seen through the video of the reconnaissance aircraft.

As for the strange wolves, I haven't fought them before, and I don't know the strength of these strange wolves.

However, the only thing that made Chen Nuo happy was that the bullets could kill these monsters!

It's just that those strange birds are extremely fast, and there are countless numbers of them.

As for their attack power, it is guessed that they are very strong, but it is difficult to accurately guess how strong they are.

However, after the fierce battle just now, he gained nearly 300 upgrade points!

In addition to the upgrade points sent by the system in the past few days, he now has a total of 875 upgrade points!

In other words, he can upgrade the shelter level!

This is undoubtedly good news for him!

Thinking in this way, Chen Nuo hastily ordered the system after issuing the order to take back the unmanned reconnaissance aircraft and fighter jets:

"System, upgrade the shelter level, choose to expand the shelter area!"

"Ding, you spend 800 upgrade points to upgrade the shelter. The area of ​​the shelter has been increased from 200 square meters to 400 square meters! The thickness of the armored door has been increased from 25 centimeters to 30 centimeters! The thickness of the walls has been increased from 20 centimeters to 30 centimeters! Increase from five centimeters to thirty centimeters!"

"Host: Chen Nuo!"

"Refuge Level: Level 6! (1,600 upgrade points are required to upgrade!)"

"Refuge equipment: Level 6 armored doors, Level 1 water source station, Level 2 power station, Level 5 scientific research base, Level 2 automatic elevator!"

"Remaining upgrade points: 75 points!"

"Ding, the level of the refuge has been raised to level six, and the immortal cultivation category in the mall has successfully loaded the formation category!"

After Chen Nuo ordered,

The system's notification sound and the shelter's attributes will appear.

Among them, what surprised Chen Nuo was that the formation category in the immortal cultivation category in the mall was actually opened!

"System, open the mall." Chen Nuodang ordered.

After studying the knowledge of cultivating immortals, he learned that formations are divided into: trapped formations, killing formations, defensive formations and auxiliary formations!

The trap is to confuse and trap the enemy.

The main kill of the killing formation is the killing formation. Anyone who enters it will be difficult to get out of it!

The defensive formation is used for defense, a powerful defensive formation is not even afraid of any attack!

There are two types of auxiliary arrays, one is to increase the user's strength, and the other is to assist the cultivator to gather the spiritual power in nature to help the user practice!

...

"It seems that I missed the formation." After reviewing the knowledge in his mind, Chen Nuo couldn't help but raise his lips.

Indeed, he relied too much on the technology of the scientific research base before, so he missed the formation among the cultivators.

You must know that the killing power in the formation is very powerful, and it can be regarded as a very powerful weapon for killing nuclear beasts.

In addition, the sleepy formation is no worse than the killing formation.

That's why Chen Nuo laughed at himself when he came back to his senses at this time.

Thinking about it, he directly clicked on the Formation category in the Immortal Cultivation category.

Immediately afterwards, under the formation category, there are four categories: killing formation, trapping formation, defensive formation, and auxiliary formation!

In this regard, Chen Nuo directly clicked on the killing array.

...

White Tiger Killing Formation: There is a phantom of a white tiger in it, which can kill those who are lower than the foundation-building stage! One hundred upgrade points required to purchase!

Qinglong Killing Formation: There are endless thunder and lightning inside it, a kind of thunder and lightning comparable to the foundation building of crossing the catastrophe! One hundred upgrade points required to purchase!

Suzaku Killing Formation: There are endless sparks in it, which can start a prairie fire, but anyone who steps into the formation will either die or be injured! One hundred upgrade points required to purchase!

Xuanwu Killing Formation: Those who step into the formation will be flooded! One hundred upgrade points required to purchase!

Four Elephant Array: An array of four divine beasts, whoever steps into it, under the Golden Core, will undoubtedly die! Buy the required 1,000 upgrade points!

Killing God Formation: You can kill God! Buy the required 100,000 upgrade points!

Evil Ghost Formation: Endless evil ghosts, if you step in, there will be no bones left! Purchase required 10,000 upgrade points!

...

Browsing these formations, Chen Nuo couldn't help but twitch the corners of his mouth at the same time.

"At least one hundred points..." While pondering, Chen Nuo clicked on the other three types of formations.

However, after browsing, the corners of Chen Nuo's mouth still couldn't help twitching.

too expensive…

Even though I am very tempted, but with the current capital, I can't afford it at all.

After thinking about it, he could only give up.

However, he understood the strength of the formation very well, so naturally he couldn't just give up like this.

"It seems that we can only rely on unmanned fighter jets to hunt and kill geonuclear beasts." Sighing, Chen Nuo went out to take back the four little guys.

Although judging from the current situation, the unmanned fighter jets are enough to hunt and kill those earth core beasts, but the lethality is not great.

But the formation is different. If you set up a killing formation and put another person in as a bait, you can hunt and kill many geonuclear beasts at once.

In this way, isn't it more harmful than an unmanned fighter jet?

Moreover, this can even reap the benefits of the fisherman.

Why not do it?
