This time, Lin Fei was well prepared.

And he had an insight into the trick of transforming soul energy from the human emperor's bloodline, so he was ready to cultivate the body quenching to the ninefold perfection in one go.

This time, Lin Fei knew the trick well, and in the process of refining his brain, he was not wasting soul energy.

Conserve soul energy as much as possible.

With his previous cultivation experience, this time Lin Fei was familiar with the road.

Soon, ten strands of blood and blood threads were extracted into the brain cells and began to refine the brain.

The previous time, refining the brain, Lin Fei only dared to use three uses with one heart, and manipulated three strands of blood and blood threads to quench brain cells at the same time.

And now, Lin Fei is able to use all his heart and ten purposes.

In addition to the fact that Lin Fei has rested enough to recuperate, it is also related to experience.

Soon, ten strands of blood and blood threads poured into the brain cells, and the efficiency was several times higher than at the beginning.

And as the brain cells were gradually refined, Lin Fei found that the soul space seemed to be undergoing abnormal changes.

The original soul space was chaotic, and the void was a void.

Rao is embellished with a star chessboard and a cosmic brain, but most of it is gray and misty, and it is not real.

And now, with the tempering of the brain, the soul space gradually becomes clear.

Soul energy also seems to have become more pure.

Feedback to the process of refining the brain doubles the tempering effect.

The human brain is home to 200 billion neuronal cells, each with a unique structure.

In the process of refining, Lin Fei found that many of these brain cells seemed to have some mysterious connection with the brain space.

This is especially true of a brain area that has been refined to the center of the eyebrows.

This is also known as the Ninth Brain Domain.

In this brain space, brain cells are different from ordinary people.

The brain cells inside seem to have been sealed by some kind of mysterious seal, so that they cannot be spied on by outsiders.

And the area where these brain cells are connected is the brain space.

There is a prokaryous of genes in the brain space.

It is also the area that maintains the origin of human genes.

The human brain is divided into nine regions, but only this ninth region has an independent subcosmic space, called the ninth brain domain.

In addition, although the soul space also relies on the brain, it is a soul universe that transcends the shackles of the human body and exists in nothingness.

and the real material universe, completely in a different cosmic dimension.

The Ninth Brain Domain Space, on the other hand, is a special subcosmic space similar to a storage space, with many mysteries, the most unique of which is that it can accommodate endless star energy.

The first eight brain domain refining processes are more complex than the other, and the difficulty is gradually increasing.

When it reaches the ninth brain domain, it is directly at the peak.

The refining process is also extremely cautious.

If you make a slight mistake, you will fall into a place of no return, and at least your brain domain will be severely damaged, and you will become a vegetative person, or your head will explode and you will die.

The refining process of the brain is different from that of other internal organs!

The other organs are all layer by layer, layer by realm, and the cycle accumulates upwards.

And the tempering of the brain must be done in one go.

Each refinement must gradually expand from the first brain domain to the ninth brain domain.

After all, although the brain is divided into nine brain domains, it is a whole after all, so the refining process must also be carried out according to a whole.

Moreover, the brain is the most critical organ of the human body, and it must be tempered with great care.

The most important thing is that all the refining process is controlled by the brain.

This is equivalent to a hardware upgrade without shutting down the computer!

The difficulty is naturally not ordinarily high!

And there must be no mistakes!

If other organs in the body are damaged, it can be repaired with time.

However, the damage that occurs during the brain refining process is basically irreversible.

This has something to do with the peculiarities of brain cells!

Nowadays, even the technological civilization at the pinnacle of the Pan-Universe Alliance has not figured out the mystery of the brain.

It can be seen that the brain is complex!

In addition, the brain is surrounded by the skull, and it is not practical to directly discharge the impurities produced after quenching through the pores out of the scalp.

It can only rely on blood vessels to help transport impurities, which are then excreted through the seven orifices, or transported to other parts of the body to be excreted through pores.

This time, Lin Fei began to discharge a large amount of black sludge from the seven holes.

In addition, after being tempered by bloodline energy, Lin Fei's brain thinking became more active, and his soul consciousness became more powerful.

Gradually, the blood threads began to increase.

11 wisps of ......

15 wisps of ......

20 wisps of ......

……

Less than a day later, Lin Fei was already able to control 100 blood threads at the same time.

At the same time, the brain cells are tempered!

Rao is like this, compared to 200 billion brain cells, it is just a drop in the bucket.

After three consecutive days of quenching.

Lin Fei's brain cells have finally completed a round of tempering!

At this time, Lin Fei was also able to control ten thousand blood threads at the same time.

The brain of the universe has also become clearer, and even the stars are connected to each other, forming clear brain circuits.

In the process of refining his brain, Lin Fei's cosmic brain ushered in a great change.

The brain's thinking ability has increased exponentially, even surpassing Lingzero at one point.

At this time, Lin Fei's brain potential was developed, and the breadth of thinking alone far exceeded that of Ling Ling.

With a single thought, it can directly override the virtual universe network of Spirit Zero.

At this time, Lin Fei suddenly had a whim in his mind.

"My cosmic brain has infinite width, if I use the cosmic brain to link the virtual universe network, I wonder if I can transfer the main body of the virtual universe network to my cosmic brain?"

As soon as this thought appeared, it lingered in Lin Fei's mind.

"Wait for the brain to be tempered for another round, reach the second round of tempering, and then try again!"

Soon, the second round of tempering was completed, and two golden halos faintly emitted from the surface of the brain cells.

Lin Fei felt that his brain thinking had been improved by two levels!

Compared to before, it is completely different!

In the second round of quenching, the depth of brain cell quenching is even deeper than before.

Lin Fei's spiritual power value skyrocketed directly.

Compared to the first round of tempering, Lin Fei's soul energy consumption directly increased tenfold.

If the human emperor's bloodline could be directly converted into soul energy, the consumption of soul energy alone would be enough for Lin Fei to cultivate for three years.

And now, this second round of tempering only took one day.

Compared with the first time to temper the brain, the time is two days shorter.

"Start trying it now and introduce the virtual universe network to my cosmic brain!"

Originally, the ontology of the virtual universe network was stored in Yanhuangxing's optical brain computer, as well as Yanhuangxing's battleship and various electronic devices.

It's always been under the control of Spirit Zero.

And the computing power of the optical brain computer cannot be increased indefinitely.

And no matter how strong the computing power is, it is not perfect.

For example, creativity, arts, humanities, etc., are far inferior to human beings in all aspects.

This gap cannot be solved with computer hardware.

And Lin Fei is now ready to make a try.

If it succeeds, then it will be able to completely get rid of the hardware shackles of the optical brain computer in the virtual universe network, and its capabilities will also increase with the continuous increase of its own cultivation.

What's more, Lin Fei can also share the supercomputing power of the virtual universe network provided by Lingling anytime and anywhere.
