Global Catastrophe: I Am Cultivating Immortals in the Refuge

"System, how many upgrade points do I have left?" Chen Nuo asked.

"5886597 points!"

More than five million points, yes!

"System, use 2 million upgrade points to buy 200,000 energy crystals! Put them directly in the material warehouse!" Chen Nuo directly ordered the system.

"Ding, you spent 2 million upgrade points to buy 200,000 energy spars! It has been stored in the material warehouse of the scientific research base!"

Hearing this, Chen Nuo directly ordered the scientific research:

"Research, make 200,000 energy spars into 20,000 jin of dark metal, and then make 20,000 jin of dark metal into 2,000 jin of nano-metal!"

"Okay!" As the sound of scientific research emerged, the mechanical arm in the scientific research base began to operate.

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

"Ten days!"

Hearing this, Chen Nuo didn't think too much, and turned to go to the retreat room to continue to practice in retreat.

There are still thirteen days until the sixth wave of disasters begins.

Chen Nuo must practice hard so that he will not suffer any harm in this disaster.

Time passed in a hurry, and ten days passed in a blink of an eye.

On this day, Chen Nuo strongly broke through the alchemy stage!

At this moment, his power soared, and the terrifying power formed a cyclone, hovering around him, causing the majestic aura in the retreat room to instantly turn into a tornado.

At this scene, Da Huang Xiaobai who was on the side couldn't help trembling in shock.

"Damn it... this aura... what kind of realm has this brother reached?" Rhubarb exclaimed.

Xiao Bai didn't speak, but just looked at Chen Nuo with fear in his eyes.

Today's them have broken through the strength of the second-order monsters a long time ago.

After breaking through, their bodies rose directly from more than five meters to more than six meters, becoming even taller and mightier.

It's just that, even so, they were afraid of the aura emanating from Chen Nuo's body.

At this moment, Chen Nuo slowly opened his eyes, and then let out a foul breath.

"According to the time, it's almost ten days." Thinking, Chen Nuo got up and left the retreat room.

There are three more days and it's time to go out.

While thinking this way, Chen Nuo had already arrived at the scientific research base.

At this time, the mechanical arm in the scientific research base has stopped operating.

In addition, on the finished product platform, each machine attracted Chen Nuo's attention.

Among them, a machine is five meters high, its upper body is oval-shaped, and its lower body is like a huge pillar.

This is very similar to the "88" in Inverse War.

Another kind of machine is two meters high, with a huge three-meter-long barrel.

Obviously, this is the spoiler.

Regarding this, Chen Nuo just glanced at it slightly, then turned around and walked towards the first floor.

Next, he summoned Hei Pi and the others back.

"Is there anything unusual outside these days?" Standing in front of them, Chen Nuo asked.

As soon as the voice fell, the No. 1 and No. 2 unmanned reconnaissance drones flew over, and then put the screen on the computer.

At the same time, Fighter One said:

"Although some people still enter Zhennan City these days, they were all driven away by us."

At the end, it hesitated for a moment, then said:

"However, just today, the monsters that used to roam the streets are all heading in one direction. It looks a little weird!"

Hearing this, Chen Nuo couldn't help but look up at it, then at the computer.

At this moment, in the screen on the computer, the monsters who were walking aimlessly on the street raised their heads one after another, and then they all headed north!

This surprised Chen Nuo.

It seems that these guys are starting to gather to attack China Refuge!

Chen Nuo secretly analyzed.

"Master, tell me, are these guys doing something?" Heipi couldn't help asking.

Chen Nuo nodded, but didn't say anything clearly.

However, everyone present couldn't help becoming nervous.

"If they come again like last time, we have the confidence to blow them up!" At this time, the UCAV said.

This time, its words no longer disgusted everyone.

Looking at the resolute gaze in their eyes, Chen Nuo couldn't help feeling a little confident.

Although he has a system against the sky, but because he died once, that's why he is so doggy.

Strictly speaking, this may just be a cherishment of life.

But now, facing the disaster again, he is no longer afraid.

"Well, come with me." Chen Nuo nodded, then got up and said.

Hearing this, everyone was stunned. Although they were a little puzzled, they didn't say anything, but followed.

Soon, everyone took the automatic elevator to the scientific research base.

"Research, use nano-metals to create a coat for them." Chen Nuo straight to the point.

"Nanometal?" Heipi and the others were stunned.

"Master, is this going to strengthen us again?" The drone fighter was a little excited.

"Go." Chen Nuo said to them.

Heipi and the others came to their production stations obediently, and then were stunned by the mechanical arm.

"Brother, what about us?" At this moment, Rhubarb was standing behind, wondering.

Hearing this, Chen Nuo looked at the scientific research and asked:

"And then use nano-metals to create an armor for them."

"Okay!" the sweet voice of scientific research came again.

Hearing this, the eyes of Rhubarb and Xiaobai couldn't help showing excitement.

But with the operation of the mechanical arm in the scientific research, Chen Nuo thought of something, so he turned and left the scientific research base, and then came to the simulated combat room.

At this time, the previous new members are still in training.

And today is the tenth day.

At that time, Chen Nuo completely forgot about it.

However, what surprised Chen Nuo was that these days, Chen Nuo didn't call to stop, but this guy really didn't stop? !

This surprised Chen Nuo.

So he quickly turned on the system of the simulated actual combat room, and then let it exit the training.

The moment Chen Nuo gave the order, Ferrari's expression returned to normal.

However, Chen Nuo couldn't help but take a deep look at it because of its look and the murderous aura emanating from its body.

"Master!" it knelt down on one knee and shouted.

"Get up." Chen Nuo said.

"I forgot to give you a name before, how about this, from now on you will be called Dark Horse!" Chen Nuo thought of something, and said again.

"Yes! Thank you, Master, for giving me the name!" The black horse clasped its fists and said.

"Well, come with me." Chen Nuo turned and walked outside.

Now that the black skins have already started to transform, his secret weapon naturally needs to be transformed.

Entering the scientific research base, Chen Nuo directly ordered:

"Create a nano-metal coat for it, and strengthen its combat effectiveness and defense in all aspects!"

"Okay!" At the same time as the scientific research answered, a mechanical arm also moved.

The black horse looked at Chen Nuo, and Chen Nuo nodded, signaling that it needn't be afraid.

Soon, the black horse was stunned by the mechanical arm, and then brought to a production table.

Chen Nuo looked ahead and asked:

"How long will it take to build them all?"

"Four days!"
