Guard the human race, summon a million Qin Tiewei at the beginning

Those alien races visibly panicked when they heard Qin Yu's words.

They chattered and communicated with each other for a while in some strange language that Qin Yu couldn't understand.

Suddenly, one of the slightly larger aliens looked up at Qin Yu.

"Human race, you can't take our crystal nucleus, otherwise, you will be retaliated by our Tianjia people, and your entire human race will be destroyed!"

When Qin Yu heard this sentence, he immediately grinned.

Before he got the system, the threat of aliens would indeed make him a little afraid!

But now, with his own system, this mere alien race is nothing but ants in front of the system, which can be destroyed easily.

Their threats seemed ridiculous.

"Really?" Qin Yu took out a small knife from his bosom nonchalantly.

His curious eyes swept over the alien race.

The aliens were all dumbfounded, feeling a chill from the bottom of their hearts.

They didn't understand why Qin Yu wanted their crystal nucleus?
Their crystal nucleus is the place where the aura in the body is stored.

It is very important to them, once the crystal nucleus is lost, the whole person will be dissipated.

It's just that this crystal nucleus is very important to themselves, but it has no effect on the human race.

Could it be that this human race is a pervert, and his hobby is to collect their crystal nuclei.

Thinking of this, the aliens shivered involuntarily.

Just when they were about to threaten again, Qin Yu had already made a move.

Qin Yu's knife directly cut across the chest of a foreigner.

As the flesh turned to the sides, bright red blood flowed down from the wound.

The strong stench almost made Qin Yu faint.

And the alien who had been disembowelled by Qin Yu was wailing terribly at this moment, and the ear-piercing voice seemed to overturn the house.

Qin Yu held his nose, and picked around with a knife in the chest of this foreign race. Soon, he found a hard, white transparent crystal.

"Could this be the crystal nucleus?" Qin Yu was overjoyed. After digging out the transparent crystal with a knife, he squeezed it carefully with his hands.

In the next second, the voice of the system came from his mind.

[The progress of the host collecting crystal nuclei reaches 1/10]

Hearing the system's voice, Qin Yu immediately confirmed that this small transparent stone was what the system called the crystal nucleus.

At this time, Huang Qianshan also stood aside, staring at Qin Yu's actions in a daze.

It's hard to understand why Qin Yu is so violent, he actually directly disemboweled the alien race.

"Qin Yu, what are you doing? Even if you want to kill aliens, there's no need to do it yourself, we can ask other people to do it..."

Qin Yu smiled slightly and explained: "I don't want to kill aliens, I want something in their bodies!"

Huang Qianshan had some doubts, and asked, "What is it!"

"This is the crystal nucleus!" Qin Yu brought the alien crystal nucleus to Huang Qianshan and said.

"Oh, I see……"

Huang Qianshan nodded.

Huang Qianshan was puzzled, there was no such thing in the body of the previous alien race.

It seems.The alien race that came to Blue Star is indeed a new type.

"By the way, what is the function of Qin Yu's alien crystal nucleus?" Huang Qianshan asked.

Qin Yu shook his head: "I don't know what effect this thing has, but I have a hunch that this is a good thing and it will be of great use in the future!"

After all, it was the system that asked him to collect this thing. From the perspective of the system, he would never be wrong, and he would not be allowed to collect useless waste.

"Okay..." Huang Qianshan nodded. Since Qin Yu didn't know, he didn't ask any more questions.

At this time, Qin Yu's eyes turned to other alien races.

There are exactly ten alien races here, who can meet the system's requirements and collect all 10 crystal nuclei.

Qin Yu even had some doubts, did the system see that there were exactly 10 alien races on the blue star, and that's why it assigned a task to let him collect ten crystal nuclei, otherwise how could such a coincidence happen.

Qin Yu didn't want to waste any more time, so he swiped the knife at the other aliens.

As if killing a chicken, Qin Yu ignored the horrific screams of these alien races and disemboweled them.Take out the crystal nuclei in their bodies.

Afterwards, Qin Yu handed over the corpses of these alien races to Huang Qianshan, and he himself returned to his home with the crystal nucleus of the alien race.

At this time, in his mind, a book about formations suddenly appeared.

After Qin Yu's simple flipping through, he found that this is a teaching of the formation method, and the core of the formation method is exactly 10 alien crystals.

Of course, this formation book looks extremely esoteric, and he won't be able to learn it in a while, so Qin Yu needs to go home and study it carefully.

After several days and nights of research, Qin Yu understood the function of this formation!

This is a terrifying fire-attribute killing formation. Once a foreign race steps into it, pure fire-attribute aura will immediately spray out.

Qin Yu immediately remembered the alien race last time, they were also very afraid of the fire attribute aura.

With this formation, wouldn't it be more effective to deal with that kind of alien race?
As soon as Qin Yu's thought came up, fine cold sweat immediately broke out on his forehead, because he thought of an extremely terrifying possibility.

With the intelligence of this system, it is impossible to do meaningless things.

The purpose of the formation given to him by the system might be to deal with alien races on Tianjia Star!
It also means that in the near future, a large number of alien races from Tianjia will invade Blue Star.

Qin Yu had seen clearly the combat power of those alien races on Tianjia Star before.

Ordinary cultivators, even if their cultivation is as high as the yellow rank, even if their number is as high as a thousand, they are not their opponents at all.

Even if the aliens on Tianjia star are afraid of the pure fire-attribute aura, how many cultivators will have the pure fire-attribute aura?

In front of the endless Tianjia alien race, it is just a drop in the bucket.

Soon, Qin Yu figured it out. This formation will be a treasure to save the human race. So far, it is the only treasure that can save the human race from the crisis.

Qin Yu learned this formation at the fastest speed, and soon he learned the essence and core of this formation.

This formation is very powerful, the only thing that makes Qin Yu feel extremely painful is that the power source of this formation is the ten alien crystal nuclei.

Alien crystal nuclei can only be found in the body of a foreign race...

But currently on the Blue Star, there are no aliens from the Tianjia Star.

Where do you find so many alien crystal nuclei to arrange the formation?
