Global Catastrophe: I Am Cultivating Immortals in the Refuge

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

　　 Inside a black hole caused by planetary debris outside the villa area of ​​Zhennan City.

　　 At this moment, an unmanned reconnaissance aircraft flew out of it at a very fast speed, followed by three unmanned fighter jets!

　　 Then, they saw that the four little guys did not leave quickly, but stopped not far away, and then turned back 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 didn't stop, so he couldn't help feeling that his move might lead these monsters out in advance.

　　 So, at this time, he feels a little nervous...

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

　　 At that time, he will become the culprit.

　　 It's just that, what made him breathe a sigh of relief and was surprised that there was no movement in that black hole?

　　 Seeing this, he was stunned.

what happened? !

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

　　 now what...

　　 He was a little dazed.

　　 Subconsciously, he controlled an unmanned reconnaissance aircraft to fly towards the black hole, wanting to find out.

　　 It's just that when the unmanned reconnaissance plane projected the dark black hole below it onto the computer, Chen Nuo was silent.

This…

　　 At this time, the black hole seemed to have restored its former calm, without the shadow of those strange birds at all.

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

　　 Come to think of it, these strange birds are not able to come out of the black hole for some reason.

　　 But, what is the reason?

　　 Of course, when in doubt, Chen Nuo could not help but breathe a sigh of relief.

　　 After all, just now, he felt that he almost brought these monsters out in advance.

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

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

　　 Currently known monsters are strange wolves and strange birds. They are very large, and the strange birds have strong speed and attack power.

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

　　 As for the strange wolves, I have never fought with them, and I don't know the strength of these strange wolves.

　　 But the only thing that makes Chen Nuo happy is that bullets can kill these monsters!

　　 However, the speed of those strange birds is extremely fast, and the number is countless.

　　 As for their attack power, according to guess, it is very strong, but it is difficult to guess exactly how strong it is.

　　 But, after the fierce battle just now, he has gained nearly three hundred upgrade points!

　　 In addition to the upgrade points that the system has given over the past few days, he now has a total of 875 upgrade points!

　　 In other words, he can upgrade the refuge level!

　　 This is undoubtedly good news for him!

　　 Thinking like this, Chen Nuo hurriedly instructed the system after giving the order to recover the unmanned reconnaissance aircraft and fighter jets:

　　 "System, upgrade the level of the refuge, choose to expand the area of ​​the refuge!"

"Ding, you consume 800 upgrade points to upgrade the refuge. The area of ​​the refuge has increased from 200 square meters to 400 square meters! The thickness of the armored door has increased from 25 cm to 30 cm! The thickness of the wall has increased from 20 cm. Five centimeters increased to thirty centimeters!"

　　 "Host: Chen Nuo!"

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

　　 "Refuge equipment: six-level armored door, first-level water source station, second-level power station, fifth-level scientific research base, and second-level automatic elevator!"

　　 "Remaining upgrade points: 75 points!"

　　 "Ding, the level of the refuge has been raised to level 6, and the mall repairing the immortal class has successfully loaded the formation class!"

　　 After Chen Nuo ordered, the system's prompt sound and the attributes of the refuge appeared.

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

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

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

　　The trap is to confuse the enemy and trap the enemy.

　　 Killing Array Master Killing is an Array of Killing and Slashing. If you enter, it will be difficult to get out of it!

　　The defensive array is used for defense, and the powerful defense array is not even afraid of any attacks!

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

　　……

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

　　 It is true that he was too dependent on the science and technology of the scientific research base before, so he omitted the formation of the immortal cultivation class.

　　 You must know that the killing power in the formation is very powerful, and it can be regarded as a very powerful weapon to kill the earth core beast.

　　 Other than that, the sleepy formation is no worse than the killing formation.

　　 Therefore, Chen Nuo laughed at herself when he recovered.

　　 Thinking, he directly clicked on the formation method in the immortal cultivation category.

　　 Immediately afterwards, there are four types of formations: kill formation, trap formation, defensive formation, and auxiliary formation!

　　 In response, Chen Nuo directly clicked on the killing formation.

　　……

　　White Tiger Killing Array: There is a white tiger phantom in it, which can kill the steppers whose strength is lower than that of the foundation building realm! One hundred upgrade points are required to purchase!

　　 Blue Dragon Killing Array: There are endless lightning within it~www.readwn.com~a kind of lightning that can be compared to the building of a base by crossing the robbery! One hundred upgrade points are required to purchase!

　　 Suzaku Killing Array: There are endless sparks in it, which can start a prairie fire, but if you step in an array, you will either die or be injured! One hundred upgrade points are required to purchase!

　　 Xuanwu Killing Array: Those who step on the Array, the water will flood them! One hundred upgrade points are required to purchase!

　　Four Elephant Array: Set in the Array of Four Mythical Beasts, if you step into it, under the golden core, you will definitely die! One thousand upgrade points are required to purchase!

　　 God Killing Array: You can kill God! One hundred thousand upgrade points required to purchase!

　　Evil Ghost Array: Endless evil spirits, as long as you step in, there will be no bones left! Ten thousand upgrade points required to purchase!

　　……

　　 Browsing these formations, Chen Nuo's heart twitched at the same time.

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

　　 However, after browsing, Chen Nuo still inevitably twitched the corners of his mouth.

too expensive…

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

　　 After thinking about it, he can only give up.

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

　　 "It seems that we can only rely on unmanned fighter jets to hunt and kill the earth core beasts." With a sigh, Chen Nuo went out and took back the four little guys.

　　 Although based on the current situation, unmanned fighter jets are sufficient to hunt down those earth-core beasts, but their lethality is not great.

　　 But the formation method is different. If you set up a killing array and put a person in as a bait, you can hunt many earth core beasts at once.

　　 Isn’t it more damage than unmanned fighter jets?

　　 And, this way you can even reap the benefits of the fisherman.

　　 Why not do it?
