One thousand kilograms of dark metal are enough to create black skin and Huolala.

As for why they are first to consider them, first, they are just ordinary cars with extremely low defense, and in addition, they are the first automakers created by Chen Nuo.

Therefore, Chen Nuo will naturally choose them first.

...

And it doesn't take fast to create such dark metals for them.

Of course, Chen Nuo was naturally not idle during this period.

Because people touched this place three times, Chen Nuo planned to enhance the shelter's defense system.

So, he came to the scientific research base again.

"Scientific research, can you create a defense system? It's the kind of alarm that comes once someone steps into us." Chen Nuo did not ask the system as soon as he asked.

After all, the system's functions are there, how can it have a defense system?

"Yes!" Scientific research quickly answered Chen Nuo.

Chen Nuo's eyes lit up in response to this.

"What materials are needed to make?" he asked quickly.

As soon as he finished speaking, a light curtain appeared on the center console:

"Defense system: a sensor that can be used when the enemy is about to enter the defense range. The range can be set is not limited. The material requires: ten kilograms of copper, ten kilograms of black iron, and ten energy crystals!"

"Just make this defense system, the range is set to within 500 meters!" Seeing this, Chen Nuo directly ordered.

"Okay!" With the scientific research answering, the robotic arm in the scientific research base started to operate.

"How long will it take to produce?" Chen Nuo asked subconsciously.

"Half an hour!"

Upon hearing this, Chen Nuo nodded and then headed towards the first floor.

"System, call out the mall to cultivate immortals." Chen Nuo ordered.

As the light curtain appeared in front of him, Chen Nuo did not think much and directly clicked on the defensive formation in the formation category.

...

Xuantian Formation: Xuantian Sect Protective Formation, which can withstand the most powerful attack in the Foundation Building Realm!

10,000 upgrade points required to purchase!

Purple Gold Formation: It can burst out with powerful defensive light curtains, and can withstand the most powerful attack of Qi Refining Cultivator!

One thousand upgrade points required to purchase!

As solid as a rock formation: It has a powerful defense and can withstand the strongest attack of powerful people in the Golden Pill Realm!

One hundred thousand upgrade points required to purchase!

Tianxuan Formation: The most powerful defensive formation of the Tianxuan Divine Dynasty, which can withstand the attack of cultivators in the God Transformation Realm!

10 million upgrade points required to purchase!

...

Looking at the formation in front of him, Chen Nuo was a little surprised.

The upgrade points required for purchasing this defensive formation are actually more than those required for attack formations.

Even the cheapest ones require a thousand upgrade points...

Sure enough, defense and attack cannot be measured together.

"I have less than 20,000 upgrade points, and I can buy a Xuantian Formation." Chen Nuo thought to himself.

"I want to buy the Xuantian Formation!" Chen Nuo ordered directly.

"Ding, you spent 10,000 upgrade points to buy the Xuantian Formation!"

As the system prompt sound appeared, four iron rods similar to lightning rods and a circular compass appeared on the table in front of Chen Nuo.

"By the way, system, do you know how strong the foundation building realm is?" Chen Nuo suddenly thought of this question.

The reason why I asked this is because although he learned the basics of immortal cultivation, he was not clear about many aspects of the problem.

Furthermore, he has not reached the foundation building realm yet, how could he know the strength that a strong person in the foundation building realm can exert?

"The strong people in the foundation building realm have powerful spiritual power, and can use their spiritual power to easily fly on swords, and can ignore the attacks of bullets and missiles. As for their attack power, they can easily destroy anything!"

Upon hearing this, Chen Nuo was stunned and a little shocked.

"Is the foundation building realm so strong?" he couldn't help but murmur.

Ignore bullets, missiles, and even destroy anything...

Isn’t this the “power” I yearn for?

Chen Nuo couldn't help but ponder.

"So, can they destroy the tank?" Chen Nuo asked hurriedly.

"Can!"

Hearing this, Chen Nuo became excited.

but…

"I'm still a big realm to enter the ranks of the foundation building realm. It seems that I still have to continue working hard!" Chen Nuo couldn't help but sigh.

Although he had tried his own strength in the simulation room, the strength of the foundation building realm was still what he yearned for.

...

After coming back to his senses, Chen Nuo planned to go out to arrange the defensive formation.

After all, the temperature began to rise, and with the ability to control the body with spiritual power, he should not be afraid of the cold.

After preparing for it, he went out alone with his backpack on his back. After all, there was no need to bother Hei Pi and the others to help in such a thing.

Furthermore, he didn't want the three outside to see the existence of Black Pi and theirs.

but…

Before leaving, Chen Nuo looked at his storage room and finally chose to take a quilt and two boxes of instant noodles.

...

After taking the automatic lift to the parking garage in the villa, Chen Nuo went directly to the entrance and exit of the shelter and looked down.

"Hey!" Without thinking too much, Chen Nuo shouted directly to the bottom.

Because the aisle is dim compared to the outside, when Chen Nuo stood there, people inside could see a figure.

They were stunned by this.

Someone!

"What...who?" the father picked up the wooden stick he carried beside him and said vigilantly.

"I am from China! Don't be afraid, the temperature outside is not very cold now. I'll take you to a place!" Chen Nuo walked downward and said.

After seeing clearly that he was a young man, the father relaxed his vigilance.

"Where? How do we trust you?" he said subconsciously.

"I have only one person, and I can't beat you three people with sticks." Chen Nuo shrugged and spread his hands.

The reason for saying this is because he does not intend to stop saving him, not because of anything else, but because these people do not know that it is a refuge there.

And, you can also meet them in this way.

In short, now he comes out without exposing the shelter at all and being the owner of the shelter.

Therefore, he naturally could not kill people to silence him. Not only that, he also chose to help them.

As for why he didn't save him before, it was because the temperature outside was too cold and he didn't dare to go out.

...

At the same time, the three people who heard this were stunned.

"But...why should we listen to you?" the father asked back.

Chen Nuo didn't say much, threw the quilt in his hand and two boxes of instant noodles and said:

"There are such supplies in the place where I take you to, and it is warmer than here. This is what I found there."

After taking the quilt and instant noodles, they were stunned.

But the woman soon became confused:

"If there was such a place, why would you take us there?"

Upon hearing this, Chen Nuo didn't think much about it and directly took out the remarks he had thought about long ago:
Chapter completed!
