"Hey, Ms. Luo, we have arrived in Zhennan City. Please answer me. Please answer me. Over, over!"

Just as the woman was waiting for Chen Nuo's reply with anticipation on her face, she suddenly made such a sound in her coat pocket.

Obviously, the rescuers have arrived!

In response, she picked up a communicator in her pocket and said:

"Received, I'm now..."

As she said that, she looked around and looked for the address name.

Soon, the four words "Xiangyu Street" appeared in front of you.

"I'm in Xiangyu Street, you can see me when you come here!" Seeing this, she replied.

After saying that, she quickly turned around and wanted to pursue the answer with Chen Nuo. However, when she turned around, only the back of the Mercedes-Benz was left in her eyes.

This scene made her stunned.

Rumble!

At this moment, the loud sound of the helicopter propeller rotating came from his ears.

Looking into the sound, there was a helicopter and several fighter jets in the sky.

Seeing this, the woman waved her hand and shouted:

"Hey! I'm here!"

...

"Master, how did you kill the monster with one sword just now?" Hei Pi was a little excited on the way.

Because Chen Nuo's attack just now was so handsome.

Just one sword cut the huge creature into two!

This kind of strength is amazing and fascinating!

"You can train well." Chen Nuo didn't want to answer this question.

At the same time, what he said is also a lie.

Well, it's a robot.

After all, robots cannot exert such power without spiritual power.

However, thinking of this, Chen Nuo couldn't help but consider this aspect.

It seems that we have to strengthen the black skin and the others a little more.

Thinking of this, Chen Nuo thought of the scientific research base.

Perhaps, if you upgrade a few more times, you will have the technology to enhance black skin and theirs.

"System, how many upgrade points are there in my remaining?" Chen Nuo asked.

Because of the mutant animals wandering outside, he can easily get about hundreds of upgrade points every day.

Therefore, he himself cannot be sure how many upgrade points he has.

“17362 o’clock!”

"How many points do you need to upgrade a scientific research base?" Chen Nuo asked hurriedly.

“25600 points!”

"It seems that the fighter jet 1 and the others have to come out and fire a few more shots." Chen Nuo pondered.

Thinking of this, he directly ordered:

"System, use 10,000 upgrade points to purchase 1,000 energy crystals, 910 are placed directly in the material warehouse of the scientific research base, and the remaining 90 are placed on the table in the living room on the first floor of the shelter."

"Ding, you spent 10,000 points to upgrade and purchase 1,000 energy crystals! Nine hundred and ten have been placed in the material warehouse of the scientific research base, and the remaining ninety are placed on the table in the living room of the shelter."

As the system prompt sound appeared, Chen Nuo and the others came to the villa area.

Although the fog illusion array has covered the entire villa area, because Chen Nuo can control the formation with his mind, they will not enter the trapped formation.

...

Entering the shelter, Chen Nuo directly ordered the six fighter brothers to divide into three teams, each team with thirty energy crystals and an energy-gathering cannon to fire guns in various places in Zhennan City.

Because the scientific research base has made two more energy-gathering guns in the past few days, six fighter jets can set off at the same time this time.

After all, this is not only fast, but also high results.

After doing this, Chen Nuo ordered the system to call out the scientific research base and upgrade it to the next level to add new craftable technology.

...

"Star Battleship: A battleship that can fly freely in the universe is not only fast, but also contains powerful artillery weapons!"

Production needs: one ton of dark metal, ten thousand energy crystals, and one thousand kilograms of copper!

"Submersible warship: After upgrading the scientific research base, this warship not only has underwater combat capabilities, but also has the ability to dive for 20,000 meters. At the same time, it has extremely strong defense due to pure black iron making!"

Production needs: three tons of black iron, one ton of dark metal, one thousand kilograms of copper, and one thousand energy crystals!

"Energy-gathering sword: This sword has two forms, which can fire energy-gathering cannons, and can also be used as weapon attacks! Because it is enhanced, there are very few energy crystals required! (can be fused into machinery!)"

Production requires: 100 kilograms of dark metal and 500 energy crystals!

"Plasma laser cannon: a cannon that can destroy anything!"

Production requires: 100 kilograms of dark metal and 10,000 energy crystals!

Plasma Spark: The emission energy of plasma laser cannons!

Making materials: One hundred energy crystals!

...

Looking at the newly added craftable technology after the upgrade, Chen Nuo's eyes lit up.

All good things!

Although these things are not available now, they can be transformed into robots with the fire of life!

In addition, the energy-gathering sword, this kind of sword can not only fire energy-gathering cannons, but also turn into a sword to attack the enemy!

You know, the power of the energy-gathering cannon is as powerful as a nuclear bomb!

Moreover, this sword can not only be used by Black Skins, but also fused on them.

In other words, once integrated, it is like an innate weapon.

In addition, the detailed introduction of plasma laser cannon, this weapon is monotonous, but it interprets everything.

"It can destroy any laser cannon!"

This is very strong!

"The dark metals add their defense power, but the attack power of the mechanical heavy sword is obviously not as high as that of the energy-concentrating sword." Chen Nuo pondered.

But, this material...

This made him silent.

Although Chen Nuo asked Hei Pi and others to collect materials these days, Chen Nuo didn't know how much materials there were.

Thinking of it, he went to the scientific research base.

"Scientific research, how much material is there?" He asked directly when he entered the scientific research base.

"There are 1,526 energy crystals, 129,373.45 kilograms of iron, 163.67 kilograms of black iron, 152.52 kilograms of dark metal, 73,628 kilograms of gold, 143,826.62 kilograms of copper, 63,548 kilograms of bricks, 527,373 kilograms of silk, and 372,636 kilograms of cotton..."

Upon hearing this, Chen Nuo couldn't help but feel a little surprised.

Unexpectedly, Black Skins are quite efficient.

However, the number of energy crystals is really small, and it seems that it is not enough to make the energy-gathering sword in a short time.

After all, he still has more than 1,500 energy crystals left. If he exchanged them for dark metal, he can only exchange them for more than 150 kilograms.

In this way, not only is the dark metal not enough, but the energy crystal not enough.

Thinking of it, he looked down at the time on Rolex.

13:55.

Well, let's talk about it for a meal.

Thinking of it, he returned to the first floor.

However, when pressing the elevator level, he was stunned.

He had raised many piglets, chickens and ducks before.

Now that the spiritual energy is revived, have they evolved?

Thinking of this, Chen Nuo pressed the fourth level.
Chapter completed!
