"Buzz!"

As Ye Yifan's practice time grew longer, the suction force on the outside world in his position continued to increase, and even the thick fog in the surrounding area was attracted, rendering the surroundings like a fairyland. A large number of stone pillars were covered with thick fog, revealing only a piece above, which was very similar to the Nantian Gate in many films and TV shows in the 21st century.

However, at this time no one was interested in paying attention to those things. Everyone in the Holy Knight Mercenary Group also knew that Ye Yifan had reached the most critical stage, and was even more vigilant and was always on guard against outsiders coming in and disturbing Ye Yifan.

As for Ye Yifan, he completely sank his mind into his body and visualized that he was a huge black hole, constantly absorbing various energy from the outside world, not only the star power, the power of the moon and the power of the sun, but also the various energy permeated in the surrounding area, absorbing it all. His body was like a bottomless pit, and he was not picky at all, swallowing all the energy.

One minute...Ten minutes...thirty minutes...

Almost every moment, a large amount of energy is attracted to Ye Yifan's body. Moreover, this suction force continues to increase, just as the energy swallowed can generate greater suction force again, bringing in a wider area.

At first, only the entire stone forest was affected, and the energy in it was absorbed by Ye Yifan. However, as time delayed, the entire foggy forest was soon shrouded in the terrifying suction force emitted from Ye Yifan's body.

At this time, Liu Tiezhu and others also retreated very wisely and did not choose to fight hard. It is still a matter of whether they can withstand it, but it will definitely affect Ye Yifan's cultivation, which is really unwise.

But not long after, Ye Yifan's "power" scope expanded beyond the foggy forest, covering hundreds of miles of surrounding areas.

Seeing this, Liu Tiezhu and others could only retreat again and again. Everyone knew that in this state, even if there was an enemy, it would not be threatening Ye Yifan. As long as he dared to get close to that area, he would be sucked into a person and fucked.

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

At this time, Ye Yifan's cultivation had reached a peak. Although the suction force generated was incomparable to a real black hole, it seemed to contain the power of laws and had a strange effect of ignoring defense. Therefore, even Li Dan, whose vitality reached more than fifty points, dared not get close to him, let alone others.

If there are really strong people in the Martial Saint Realm coming, you may be able to approach Ye Yifan without being affected, but if there are strong people of that level that really appear, Liu Tiezhu and others will be irresistible.

The powerful people in the Martial Saint Realm are completely different from ordinary strong people. They can even enter the hidden space at any time. It is up to them to decide whether they want to fight or escape. Therefore, even if the real combat power of Li Dan and others is far greater than that of the Martial Saint Realm, they dare not say that they will definitely win the opponent. At most, they will be caught off guard by the opponent. If the powerful people in the Martial Saint Realm see the combat power of Li Dan and others and are determined to avoid it, then they will have no choice.

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

However, Liu Tiezhu and others formed a circle, surrounding the Mist Forest and a large area around it. However, the circle was too big, and the distance between the two people was more than fifty miles, which could only serve as a warning. If someone really wanted to go in, it was very likely that they would miss it!

At the same time, Ye Yifan felt that it was almost the same. He felt the enormous 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 familiar with the hidden space now, and he is not as awkward as other martial arts masters 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 accumulated in his body into his forehead in a special way, where there was the most mysterious cerebral cortex in the human body.

Speaking of which, the brain includes the terminal brain and the dibrain, where the terminal brain is divided into the left and right cerebral hemispheres, and the brain is divided into three parts: the cerebral cortex, the cerebral medullary and the basal nucleus. Among them, the cerebral cortex is gray matter covering the surface of the terminal brain.

In the past, no one dared to touch his brain. This is the most sophisticated part of the human body and cannot be analyzed at all, let alone conducting deeper research on it.

However, when the hidden space was discovered, it was quite coincidentally produced brain nuclei in some human bodies. Later, after a series of studies, it was found that the brain nuclei is the best medium for communicating hidden space.

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

This is consistent with the method of opening hidden space by most civilizations in the universe.

According to research, the end brain consists of about 14 billion cells and weighs about 1400 grams, and the thickness of the cerebral cortex is about 2-3 mm and the total area is about 2,200 square centimeters. It is estimated that about 100,000 brain cells will die every day (the more you don’t use the brain, the more brain cells die). The capacity of a person’s brain stores information is equivalent to 10,000 libraries with 10 million books. The view reached in the early 21st century is that people who are good at using the brain will only be able to use the brain in their lives.

10% of the brain-lossing ability, but later science proved that this view was wrong. Humans use their brains at 100%, and there are no idle cells in the brain. The main component of the human brain is water, accounting for 80%. Although the brain only accounts for 2% of the body's weight, the oxygen consumption reaches 25% of the whole body's oxygen consumption, and the blood flow accounts for 15% of the heart's blood output. The blood flowing through the brain in one day is 2,000 liters. If the energy consumed by the brain is expressed by electricity, it is about 25 watts.

It is precisely because people's use of the brain has reached 100%, so there is great controversy about the location of the brain nucleus. At first, everyone believed that the brain nucleus should be placed at the core of the brain, that is, the basal nucleus in the brain medulla. However, this view was soon overturned. After a series of verifications, people finally decided to place the brain nucleus on the forehead. There is a cerebral cortex here, but squeezed can still make a little space to form a brain nucleus, which will not affect the normal life behavior of the brain owner.

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

"Click!"

However, Ye Yifan obviously underestimated the energy he drew from the outside world. Other martial arts practitioners were quite conservative when they reached 10 points to try to communicate with hidden space. Even the practiced skills only absorbed a certain kind of energy, and not many actually entered the body. Generally speaking, only 10 units of crystal energy, and at most it would not exceed 30 units of crystal energy.

But Ye Yifan, within the three hours just now, he sucked all the energy in the area of ​​hundreds of miles. At the same time, he did not let go of the power of the star, the power of the moon, and the power of the sun that came from the sky, and integrated it into his body.

Under Ye Yifan's domineering swallowing, at least seven or eight thousand units of crystal energy were absorbed into his body. And until now, Ye Yifan had not stopped yet, and was still drawing energy from the outside world, and even the energy underground was sucked 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, with the experience provided by Liu Tiezhu and others, he succeeded in one go, but the quality and "quality" of this mind were too amazing!

That’s right, it’s mass and “mass”. The previous mass represents the real weight, which also includes size, while the latter mass refers to the energy contained in the crystal nucleus!

If it were other martial arts practitioners, when the brain core was just formed, they were about the size of a needle tip. Many people still felt uncomfortable in their heads and even felt unbearable pain. After all, a "small sand" suddenly appeared between the cerebral cortex and the skull, and no one would feel comfortable!

However, Ye Yifan's brain core was as big as a fist, which completely squeezed his brain aside. If it weren't for the soldiers under Ye Yifan's command constantly providing him with surplus vitality to replenish him, he would have died completely at the moment when the brain core was formed. Even now, he felt uncomfortable, and instantly rolled down from the high stone pillar and fell heavily to the ground.

Then, Ye Yifan climbed up with difficulty, sat cross-legged on the ground, trying hard to adapt to this change, but he soon discovered that the huge brain core that appeared in his head seemed to be still frantically absorbing energy from the surroundings and continued to grow bigger!

"What should I do about this brain core? He is so domineering, and he has a big fist and is still not calm. How big does it have to grow to be satisfied?" Ye Yifan couldn't help but complain at this time, but he had no good idea, so he could only let it go!

The brain core is also very special. It is not only large in size, but also has a very high density. The efficiency of absorbing energy from the surrounding area is amazing, and it will grow bigger in a short while.

"Hiss!"

Faced with the invasion of the brain nucleus, Ye Yifan's brain was squeezed and almost exploded. At this time, he was like Sun Dasheng who was struggling desperately under the tight spell. No matter how capable he was, he could not bear the heart-wrenching pain!

"Ao!"

Unable to help the pain coming from his head, Ye Yifan finally screamed, and then he was out of control, running around in the stone forest, and shouting, as if crazy!
Chapter completed!
