"Buzz!"

As Ye Yifan's ** time became longer and longer, the suction of his location to the outside world was increasing, and even the dense fog in the surrounding area was attracted, rendering the surroundings like a fairyland, and a large number of stone pillars were covered by the dense fog, only revealing only a section of the top, which is very similar to the Nantianmen in many films and television in the 21st century.

However, at this time, no one had the heart to pay attention to those, and everyone in the Holy Knight Mercenary Regiment also knew that Ye Yifan had reached the most critical stage, and they were even more vigilant, in case outsiders came in at any time to disturb Ye Yifan.

As for Ye Yifan, he completely sank his mind into his body, visualizing himself as a huge black hole, constantly swallowing all kinds of energy from the outside world, not only the power of the stars, the power of the moon and the power of the sun, but also the various energies permeated in the surrounding area, and absorbed them all. And his body is like a bottomless pit, and at the same time he is not picky at all, swallowing all his energy.

One minute...... Ten minutes...... Thirty minutes......

Almost every moment, a large amount of energy was attracted and entered Ye Yifan's body. And this suction power is constantly increasing, just as the energy that has been swallowed can create a larger suction force again, encompassing a wider area.

At the beginning, only the entire stone forest was affected, and the energy in it was absorbed by Ye Yifan. But as time passed, soon the entire misty forest was enveloped in the terrifying suction emanating from Ye Yifan's body.

At this time, Liu Tiezhu and the others also retreated into the distance very wisely, and did not choose to shake hard, in that case, whether they could resist it or not, but it would definitely affect Ye Yifan's **, which is really unwise.

However, it didn't take long for Ye Yifan's "sphere of influence" to expand beyond the misty forest, enveloping the surrounding area for hundreds of miles.

Seeing this, Liu Tiezhu and others could only retreat again and again. Everyone knew that in this state, even if there was an enemy, he would not be able to threaten Ye Yifan, as long as he dared to approach that area, he would be sucked dry.

Even if a mecha enters the area around Ye Yifan, the energy in it will be absorbed and lose power.

At this time, Ye Yifan's ** has reached a peak, and although the suction power generated is incomparable to that of a real black hole, it seems to contain the power of the law, with a strange effect of ignoring defense, so even Li Dan, whose own vitality has reached more than fifty points, does not dare to approach, let alone others.

If there is really a strong person from the Martial Saint Realm coming over, maybe he can get close to Ye Yifan unaffected, but if there is really a strong person of that level, Liu Tiezhu and the others will be difficult to resist.

The powerhouses of the Martial Saint Realm are completely different from ordinary powerhouses, they can even enter the hidden space at any time, and it is up to them to decide whether they want to fight or escape, so even if the real combat power of Li Dan and the others has far exceeded that of the powerhouses of the Martial Saint Realm, they dare not say that they will win the other party, at most they will be caught off guard, if the powerhouses of the Martial Saint Realm have seen the combat power of Li Dan and the others, and they are bent on dodging, then they will have no choice.

So it's useless to worry about it now, so I can only wait patiently.

However, Liu Tiezhu and the others still formed a circle, enclosing the misty forest and a large area around it, but this circle is too big, the distance between the two people is more than fifty miles, it can only play a warning role, if someone really wants to enter, it is very likely to be missed by them!

At the same time, Ye Yifan felt almost, he felt the abundant energy in his body, and decided to start communicating with the hidden space.

Since he had communicated with Liu Tiezhu and others before, Ye Yifan is also familiar with communicating with the hidden space now, and there is no jerkiness of other martial arts powerhouses to communicate with the hidden space for the first time.

"Buzz!"

According to the experience of Liu Tiezhu and others, Ye Yifan tried to inject the energy gathered in his body into his forehead according to a special route, where there was the most mysterious cerebral cortex in the human body.

Speaking of which, the brain includes telencephalon and diencephalon, of which the telencephalon is divided into left and right cerebral hemispheres, and at the same time, the brain is divided into three parts: cerebral cortex, cerebral medulla, and basal nucleus. The cerebral cortex is the gray matter that covers the surface of the telencephalon.

In the past, no one dared to use their brains, and here is the most delicate part of the human body, which cannot be analyzed, let alone studied at a deeper level.

However, when the hidden space was discovered, it was quite coincidental that the brain nucleus was produced in some people, and later after a series of studies, it was found that the brain nucleus is the best medium to communicate with the hidden space.

It is precisely because of this that various methods of communicating hidden spaces have gradually been formed.

And this is in line with the method of most civilizations in the universe to open the hidden space.

According to the study, the telencephalon is composed of about 14 billion cells, weighs about 1,400 grams, and the thickness of the cerebral cortex is about 2-3 mm, the total area is about 2,200 square centimeters, and it is estimated that about 100,000 brain cells die every day (the more the brain is used, the more brain cells die). A person's brain stores information equivalent to 10,000 books in a library with 10 million volumes, and the early 21st century came to the idea that the person who is the best at using his brain will only use 10% of his brain power in his lifetime, but later science proved that this view is wrong, and human beings use their own brain at a rate of 100%, and there are no idle cells in the brain. The main component of the human brain is water, which makes up 80%. Although the brain accounts for only 2% of the body's body weight, it consumes 25% of the body's oxygen consumption, and the blood flow accounts for 15% of the heart's output, and the blood flow through the brain in a day is 2,000 liters. The energy consumed by the brain is equivalent to about 25 watts if the electrical power is used.

It is precisely because people use the brain at a rate of 100%, so the location of the formation of the brain nucleus is also very controversial, and it was initially decided that the brain nucleus should be placed in the core of the brain, that is, the basal nucleus in the cerebral medulla, but soon this view was ** After a series of verifications, people finally decided to place the brain nucleus in the forehead, where there is a cerebral cortex, but squeezing can still free up a little space to form a brain nucleus, which will not affect the normal life behavior of the brain owner.

And what Ye Yifan is doing now is to form a brain nucleus on his forehead, once this brain nucleus is formed, he can use it to communicate with the hidden space in the future.

"Click!"

However, Ye Yifan obviously underestimated the energy he absorbed from the outside world, and other martial arts cultivators were quite conservative when they began to try to communicate with the hidden space when their vitality reached 10 points, and even **** would only absorb a certain kind of energy, and there were not many that really entered the body, usually only equivalent to 10 units of crystal energy, and at most no more than 30 units of crystal energy.

But Ye Yifan, in the three hours just now, he didn't refuse, and absorbed all the energy in the area within a radius of hundreds of miles, and at the same time, he didn't let go of the power of the stars, the power of the moon, and the power of the sun shot from the sky, and all of them were integrated into his body.

Under Ye Yifan's domineering swallowing, at least seven or eight thousand units of crystal energy energy were absorbed into his body, and until now, Ye Yifan has not stopped, he is still continuously absorbing energy from the outside world, and even the energy in the underground has been absorbed by him.

In this case, when Ye Yifan began to try to form a brain nucleus on his forehead, although he did not encounter any twists and turns, under the experience provided by Liu Tiezhu and others, he succeeded in one surname, but the quality and "quality" of this mind are too amazing!

That's right, it's mass and "mass", the former mass represents the real weight, including the size, and the latter mass refers to the energy contained in the crystal nucleus!

In other martial arts cultivators, when the brain nucleus was just formed, the size was only about the size of a needle tip, and there were still many people who felt uncomfortable in their heads, and even the pain was unbearable, after all, a "small sand" suddenly appeared between the cerebral cortex and the braincase, and no one would feel comfortable!

But Ye Yifan's brain nucleus is the size of a fist, completely squeezing his brain aside, if it weren't for Ye Yifan's soldiers constantly providing him with surplus vitality to replenish, I'm afraid that Ye Yifan would have completely hung up the moment the brain nucleus was formed, even now, he also felt uncomfortable, and instantly rolled down from the high stone pillar and fell heavily to the ground.

Then, Ye Yifan got up with difficulty, sat cross-legged on the ground, and tried hard to adapt to this change, but he soon found that the new huge brain nucleus in his head seemed to be frantically drawing energy from the surroundings and continued to grow!

"What should I do with this brain nucleus? It's so domineering, it's the size of a fist, and it doesn't stop, how big does it have to grow to be satisfied?" Ye Yifan couldn't help but complain at this time, but he had no choice but to let it go!

And that brain nucleus is also very special, not only is it large, but it is also extremely dense, and the efficiency of drawing energy from the surrounding area is very amazing, and it will become larger in a short time.

"Phew!"

Faced with the invasion of the brain nucleus, Ye Yifan's brain was squeezed to the point of exploding. At this time, he is like Sun Dasheng who is struggling desperately under the curse of hoops, no matter how great his ability is, he can't bear the heart-wrenching pain!

"Whew!"

Unable to hold back the pain in his head, Ye Yifan finally screamed out, and then he was out of control, constantly running around in the stone forest, shouting at the same time, like crazy!

In fact, Ye Yifan really felt that he was about to go crazy, if he continued like this, his head would be completely invaded by the brain nucleus, and in that case, he would not be far from death! You must know that the vitality that Ye Yifan consumes every second is an astronomical amount at the moment, and the surplus vitality provided by the soldiers under his command will soon be exhausted -- the damage caused by the direct attack on the brain is quite amazing! )
