Liu Fei finally withdrew his hand, looking at the red back of his hand and the scratches on it with tears in his eyes.

Wounded, wounded again!

It hurts!

I want to kiss, hug, and lift high.

Liu Fei was hypocritical for a long time, and found that there would be no one in the house to comfort him except for the system's son.

Count on the son of the system? It is better to count on your own hammer.

He reluctantly opened the system panel.

"I said, this thing is so heavy, you give Lao Tzu a hint to die?"

It's a shame that Liu Fei still feels a little guilty in his heart today, and feels that the son of the old system is a little damaged, and this thing is a grandson.

However, after opening the panel, Liu Fei was stunned.

The first sentence above.

"The weight of the object is extremely high, so do not touch it with your hands after it has been formed. ”

That's embarrassing.

Liu Fei coughed lightly and chose to ignore it, and he continued to read the system instructions.

"The fifth-generation aura book power core device of the human race, 'Darkest Light', has a large number of aura arrays engraved inside, which can effectively improve the utilization rate of aura. ”

The fifth-generation Reiki Book Power Core Device!

Liu Fei was so shocked by this sentence that he stood up suddenly, and he couldn't even care about the sharp pain in his hands.

The Power Core Device of the Book of Reiki is the core that connects the Scholars' Temple of Knowledge, which is wrapped in the Essentia of Truth and plays a role similar to the exoskeleton armored power furnace, drawing the Scholar's Aura from the Temple of Knowledge, and at the same time converting the Aura into an aura with the same properties as the essentia through the assimilation of the Essentia to the Aura.

Then, the scholarship compiled in the Book of Reiki is released again through the power core device, ensuring that the scholarship can be released stably and will not be easily defeated due to the fierce battles in the outside world.

In short, it is an important device for stabilizing the input and output of Reiki.

Originally, Liu Fei had already negotiated with Nielsen Supreme that the Holy Land of Science would provide the best Reiki Book power core device, the Eagle, for Liu Fei to use.

This is a new type of equipment that has only been successfully implemented in the laboratory the year before last, and even most of the Supreme Pioneers have not obtained it.

According to the general standards of humans, the 'Eagle' can be regarded as a third-generation core device, but it will definitely take six to eight years to completely finalize it.

This is what shocked Liu Fei the most.

The core device provided by the system to him is actually the fifth generation!

Where did this thing come from?

Liu Fei's expression was serious, and for the first time, he asked the system in a serious and even stern tone: "How did you get this thing? from a secret research laboratory, or independent research and development, or ...... From the future?"

Although the things provided by the system before were magical, they had never been connected to this world, so although Liu Fei had always wondered about the existence of the system, he had never thought about it.

But now that he has seen the core power plant that belongs to this world system, this can't help but make him delve into what the source of the system is.

How exactly did these magical black technologies come about?

As soon as he was preparing to make the Book of Reiki, it was very thoughtful to provide itself with a powerful core power unit.

It's a bit of a coincidence.

However, the system still chose to ignore it coldly.

No matter how Liu Fei asks questions, as long as it doesn't conform to the procedure, he will ignore it!

Liu Fei had no choice but to give up temporarily.

At least for now, my son still loves himself, as long as he sits right, everything else is easy to say.

Regarding Cohen's joining the school of differential geometry, Liu Fei put forward several conditions.

The first one is the apprenticeship, where you take out a thousand pieces of Essence of Truth in one day, of any type.

In exchange, he can provide the corresponding absolute space-time attribute essentia.

After precise design and calculation in the system supercomputing center, Liu Fei believes that in order to undertake the comprehensive aura book of all categories, it is necessary to carry out ultra-high compression of truth essentia in order to complete many academic transformations.

And it would take a special medium to make this crazy design a reality.

Medium aside, in the first round of transactions with Edward, Liu Fei exchanged 1,400 pieces of Truth Essence.

After this period of consumption, there are still about 1,300 pieces left.

The data designed and given by the system is that at least 1,900 pieces are needed, and considering the loss in the production process, Liu Fei needs at least 2,300 pieces to ensure that there will be no problems in the production.

One can imagine how ugly Cohen's expression was when he knew that Liu Fei wanted so much truth essence in one day.

There is also a limit to the greed for money, and if you specifically want a certain Essentia of Truth, it can be understood that you need to make a book of Reiki.

What the hell is any attribute limit?

Moreover, a college student makes a book of aura, fifteen yuan is already the limit, where does he get such aura support?

Regardless, Cohen agreed.

Liu Fei looked at the messy room, and sighed in surprise and confusion, he was bound by his son in his life.

Regardless of whether the future is good or bad, let's wait and see.

……

Early the next morning.

Liu Fei was woken up by the phone.

It's Cohen Edward.

Old Kobe was still in a hurry as he imagined, and he actually managed a thousand pieces of truth essence in one night.

Liu Fei touched his chin, it seems that the Edward family still has a lot of potential to dig up, and the speed is quite fast.

Outside the door, there was a sharp roar unique to Demon Calamity 1, which eliminated Liu Fei's last trace of sleepiness.

Liu Fei stretched his waist and opened the curtains, and suddenly saw a first-order demon calamity 1-roaring under the black pressure and picking up the window.

The two sides stared at each other, and when they saw Liu Fei's demon calamity, they suddenly became more irritable, constantly attacking the academic defense line on the periphery of the house, stirring up layers of aura ripples.

Looking at the group of strange shapes across the window from him, Liu Fei sighed.

If it weren't for the fact that the house of the laws of nature was made uninhabitable by the core device, he would not have come to live at the Gate of War if he was killed.

After Liu Fei washed up briefly, he went to the main campus to wait for the arrival of the Truth Ingena.

Leave the room that the Gate of War has provided for you.

Outside is a special world that simulates the living environment of the demon scourge, and there is a bloody atmosphere and crazy will everywhere.

The reason why the demon scourge is terrible is because of its special contagious nature.

No matter what kind of creature it is, as long as it is contaminated by the blood of the core demon scourge, it will lose its mind in an instant and become a mad creature that can only attack.

These polluted creatures are called the Outer Demon Scourge Group, and they can also advance, but they cannot reach the top of the Demon Calamity.

And the group that originally rushed out of the outer space is also called the core demon scourge group, they are the most primitive race, similar to the sin royal family, with the purest mad bloodline.

The biggest difference between the two is that although the core demon scourge group is crazy, they also have a certain amount of sanity, and the higher the rank, the stronger the sanity.

So in the Demonic Occupation Zone, you can't see any creatures.

Wherever they set foot there were only demons, and demons, and demons.

Each door has a special passageway.

Although the gate of war is crazy, it does not make people fight with the demon disaster when they have nothing to do.

From above, these passages are connected to each other, forming a dense spider web that leads to the main campus.

Cohen's men were already waiting there.
