Global Catastrophe: I Am Cultivating Immortals in the Refuge

"Is it dead?" The colonel asked subconsciously, looking at the Tiger King who was submerged in thick smoke.

In fact, he himself didn't know who he should ask, and he didn't know who would answer him.

However, by coincidence, he still expressed his doubts.

Soon, the smoke cleared.

Everyone looked intently, under the thick smoke, the Tiger King's figure was looming, and he seemed to be standing still.

At that moment, everyone couldn't help but "click" in their hearts.

not dead? !

Doubts emerged in everyone's mind.

Roar!

Suddenly, a roar resounded from the thick smoke, and the terrifying sound wave instantly dispersed the looming thick smoke!

The Tiger King's figure appeared from it, but he shook his head violently, shaking the dust off his body, but his eyes were full of contempt.

It's like saying: How can such an attack seem to be scratching an itch?

"How?!" Countless people were dumbfounded.

It can be said that the attack of Fighter Plane No. 3 just now is powerful enough.

But, just like that, Tiger King still didn't seem to have suffered any damage!

"This..." The display screen of Fighter Plane 3 was full of sluggishness.

"Get ready to meet the enemy!" Fighter No. 1 said in a deep voice.

As soon as the words fell, the wings between the hands of the three people ejected, and the bullet tubes and gun barrels on their bodies also ejected.

boom!

At the same time, other places are still fighting.

Heipi and the others ignored this side, and instead fired concentrated energy cannons in their respective positions to attack the monsters.

Their offensive is very strong, and almost every shot can take away thousands of monsters!

All of a sudden, the number of monsters was greatly reduced.

As there were fewer monsters in some directions, Heipi and the others obeyed Chen Nuo's order to fire concentrated cannons in other directions.

...

"This King Tiger's defense is extremely strong, and its attack power is terrifyingly strong. Even the three brothers of the fighter plane can't kill it." Chen Nuo looked at the screen in the reconnaissance plane and fell into deep thought.

At this moment, he knew that he had underestimated the strength of this "king".

"System, how many upgrade points do I have?" Chen Nuo asked, thinking of something.

"Click to upgrade!"

The system's answer surprised Chen Nuo.

More than three million upgrade points.

These monsters are worth a fortune!

"Master, this big guy's defense is too strong. Even No. 3's sword just cut open its flesh, and it can't hurt it at all!" At this time, the voice of Fighter No. 1 came from the scout plane. came from.

Their communication is connected, so Hei Pi and others can use the reconnaissance plane to talk to Chen Nuo.

In this way, it was also convenient for Chen Nuo to give them orders.

"Can you hold it?" Chen Nuo asked.

As long as they can hold back the tiger king, they can hunt those monsters openly.

Until these monsters are all dead.

At that time, Tiger King will definitely retreat, even if he can't kill it.

That's why Chen Nuo asked like this.

Hearing this, Fighter No. 1 was silent.

The Tiger King's blow just now almost took it away, so it didn't dare to guarantee it at all.

"If it doesn't work, I'll help you!" At this time, Hei Pi said.

"No, you can deal with the monsters in the sky at ease!" Chen Nuo said.

Now there are only four of them in the sky to attack those flying monsters.

As for the creatures on the ground, only fighters 4 to 6 can deal with them.

So, whoever helps Fighter No. 1, then these monsters will kill them!

That's why Chen Nuo objected to Hei Pi's idea.

However, he didn't think much about it, he clicked on the map and searched for the refuge in Guodu.

Soon, a journey of 413 kilometers appeared in front of Chen Nuo.

"System, how many upgrade points are needed to upgrade the shelter?" Chen Nuo asked.

The space portal in the shelter can now teleport at will within a range of 100 kilometers.

And if it is upgraded to a range of more than 400 kilometers, then Chen Nuo can go to support in an instant.

Although Chen Nuo didn't want to do it himself, under the current situation, Chen Nuo had no choice but to leave.

"Ding, one million upgrade points are needed to upgrade the shelter. After the upgrade, the area of ​​the shelter will remain the same. The teleportable range of the space portal will be increased from 100 kilometers to 200 kilometers, and the thickness of the surrounding walls will be changed from 75 centimeters. Increase to 80 centimeters!"

a million points...

hiss...

Chen Nuo was a little annoyed, but seeing the countless prehistoric creatures on the screen, he still chose to upgrade.

"Ding, you spend one million upgrade points to upgrade the shelter, the level of the shelter is increased to level 16, the area of ​​the shelter remains unchanged, and the distance that the space portal can transmit will be increased from 100 kilometers to 200 kilometers! The thickness has been increased from seventy-five centimeters to eighty centimeters!"

"How many upgrade points do you need to upgrade the shelter again?" Chen Nuo asked again.

Two hundred kilometers, obviously can't go to the refuge in Guodu.

"Ding, upgrading the shelter again requires two million upgrade points. After the upgrade, the level of the shelter will be increased to level 17, the area of ​​the shelter will remain the same, and the teleportable distance of the space portal will be increased from 200 kilometers to 400 kilometers. The thickness of the walls around the shelter will be increased from 80 centimeters to 85 centimeters!"

Hearing this, Chen Nuo couldn't help feeling a little bit pained.

Originally there were more than 3 million upgrade points, so once the upgrade is done, it will be gone immediately.

Of course, I thought so, but Chen Nuo didn't hesitate and chose to upgrade directly.

"Ding, you spend two million upgrade points to upgrade the shelter, the level of the shelter is raised to level 17, the area of ​​the shelter remains unchanged, and the teleportation distance of the space portal has been increased from 200 kilometers to 400 kilometers! The walls around the shelter have changed from Eighty centimeters has been raised to eighty-five centimeters!"

When the system's notification sound appeared, Chen Nuo looked at the computer screen.

At this moment, in the screen, the three fighter brothers are fighting the Tiger King.

The three were very smart, firing shells continuously, and did not use their wings to attack at close range.

Although the attack power of the cannonballs against the King Tiger is extremely low, not even as good as that of the wings, the King Tiger's attack power is too strong, and they dare not be attacked at the same time.

Furthermore, Chen Nuo just said to hold back the Tiger King.

It's not killing the Tiger King!

However, they teased the Tiger King so much that it angered it.

Roar!

However, it roared, instantly knocked away countless shells with just the sound waves, and then killed the tank that was firing at him in a counter-routine manner!

"Not good!" Fighter No. 1 was taken aback, and rushed over in an instant without thinking much about it.

The other two followed closely behind.

However, to the astonishment of the three of them, the King Tiger actually stopped attacking the tanks and humans in front of them at the same time as the three of them were killing them.

Huge claws whizzed towards the terrifying claw wind, and it was difficult for Fighter No. 1 to dodge, and was instantly knocked out, smashing towards the group of monsters!

boom!

The smashing of Fighter Plane No. 1 directly killed many monsters and caused a violent earthquake.

The people who watched this scene were all stunned!

This Tiger King has an extraordinary IQ!
