The pages of the last chapter of the first volume of the "Brain Phage Heart Codex", which was placed on the table, "Heart Eater", turned on its own.

The content of 'heart devouring' is completely different from the previous three chapters, this chapter has no so-called physical transformation at all, and the core content of the so-called heart devouring is not what is to devour the heart, but a theoretical, perceptual thing.

The inner point is that Zhang Chen needs to be able to eat the real 'heart', a heart that exists within the soul.

The exposition of this heart alone is about ten pages long, and many places need to be understood and analyzed inwardly. If Zhang Chen hadn't stepped into the path, it would have been impossible for Zhang Chen to complete the understanding and comprehension of the mind devouring after persevering in the third chapter.

It takes at least ten days to rest in consciousness, and the pure theoretical knowledge of 'devouring the heart' took a whole year to comprehend the pure theoretical knowledge of 'devouring the heart', and on the way, there were some key things that touched the heart that became an opportunity to comprehend the 'devouring of the mind'.

Zhang Chen didn't have that much time, and it had already taken him nearly a month to comprehend the second and third chapters.

At this moment, the situation in the outside world has become very bad, because of Yu Ming and Evil Min's actions, as well as the physical consumption of the green ghost and others, and even death...... All of this overflowing energy is absorbed by the independent world, and then through the device set up by Jizo, the brain of Francis is driven to complete the process of assimilation into the human world.

Driven by the huge energy of so many tasks, even without the special energy supply of Zhang Chen's core, the human assimilation rate has exceeded the 70% mark in the past twenty days, and the result is that the land on the earth has been shattered, and even many areas have begun to have devastating disasters of more than thirteen levels.

The only places in the human world that have been safeguarded are the prison envoy headquarters of major countries, as well as some cultivator sects with rich backgrounds.

…………

Zhang Chen, who was originally in a state of running, ran for less than two seconds before his pace slowed down. Becomes normal walking.

The reason is very simple, Zhang Chen feels that although the intake of a large amount of perception in the running state seems to be a once-in-a-lifetime opportunity, if his foundation is not sufficient, no matter how much perception he has, it will only be chaotic, and it will not be able to achieve the effect of water.

"The predecessor can actually think of the 'heart' of the prison envoy, and in fact, it is also the heart of every conscious creature."

Zhang Chen's face showed just the right smile, no more, no less. The footsteps began to become soft and slow, as if each step felt the rhythm of the earth, the soles of the feet attached to the earth, the body to the soil, and the mind to merge into the whole path.

'Eating the heart' does not literally mean devouring the heart, but swallowing the inner impurities produced by the environment in the invisible heart of human beings, and the negative emotions and emotional accumulation caused by the influence of various human feelings. Some fragments of debris that have settled in the corners of the heart.

Zhang Chen is purifying his soul with every step he takes, and is devouring the invisible accumulation formed by the 'heart' in the growth path through an invisible and virtual mouth, and an incomparable sense of transparency begins to be born in the heart, and the whole process is not as painful and difficult as the previous three chapters, but a kind of relaxation, a kind of comfort, and a kind of soul sublimation.

"Ethereal feeling...... I could feel the soul supporting the body, and I could clearly feel that the body contained the soul within. The heart is just a core of the human body. The true 'mind' exists in any part of the body, feeling everything in the outside world all the time. Recording everything. ”

"And yet...... I've emptied everything now. ”

Zhang Chen slowly opened his eyes at this moment, and his right hand swinging forward touched a cold object.

It seemed to be an endless and winding road, but at this time, a wooden door with a height equal to his height appeared in front of Zhang Chen, and what Zhang Chen's right hand touched happened to be a metal handle embedded in the wooden door, as long as he turned down, the wooden door leading to the location in front of him would open.

However, the palm that was about to rotate was slowly withdrawn.

After a brief and ethereal reflection, Zhang Chen did not open the door to a new world as it should be. Instead, he slowly turned his body and looked at the path behind him.

The rarity of this kind of opportunity, Zhang Chen has already been very clear in his heart at this time.

But there was an invisible feeling in himself, a feeling of not being disturbed by any distractions, which drove Zhang Chen to return along the original path. Walking on the road that has been walked, there is no new insight. Just walk along the path you've walked, look at every inch of land that has left your footprints, and return the way you came.

Zhang Chen's body in the outside world began to change again at this moment.

Flesh devouring - every inch of flesh and blood in the body is bitten and crushed and sent into the digestive pool for meticulous digestion, without a trace of residue remaining, and the flesh and blood digested through the abdomen are re-used as Zhang Chen's body.

Bone Eating - Initialize the bones of the whole body, return to the perfect 1008 primary bones when the original bone was formed, and then throw the bones into the digestion pool one by one, so that each bone and a white navel are fused with each other to give the bones the ability to snort and make them independent.

Brain phagocytosis - the separation and transformation of the teleencephalic tissues responsible for controlling movement, generating sensations and realizing advanced brain functions at the molecular level, so that cranial nerves can uniquely exist between the body, taking into account the subtle and precise control of every inch of the body.

However, when Zhang Chen returned along the original path, the three important body compositions of flesh, bones, and brains that had changed through the "Body Phagoagosome Heart Codex" began to change and merge in essence, and this change made the people in front of him who were trying to absorb Zhang Chen's energy feel shocked, and it could even be said that there was a trace of fear.

The probability and frequency of being able to allow the consciousness to enter the path of its own enlightenment is extremely small.

In the eyes of others, it is a great opportunity, and because of the unknown nature of this situation, the time that can be walked inside the avenue is also random, and it will automatically end at any time. And coming here not only requires the ultimate concentration on the way to enlightenment, but most importantly, when reaching the extreme, there will be an occasional illusory opportunity, and only by seizing it can you come here.

But even a second of time can be a huge gain for those who can seize the opportunity.

It's just that Zhang Chen's situation of going back has never happened, and no one would be stupid enough to take advantage of such a precious opportunity to look back at the road he has traveled and the Tao he has understood. As long as every step forward here is equivalent to three days of serious meditation on weekdays, even five or ten days.

If Zhang Chen told others about coming here and turning back, he would treat Zhang Chen as a fool who didn't know how to cherish opportunities.

It's just that the reason why Zhang Chen does this is completely freewheeling, what his heart moves, where he wants, and where God goes.

Zhang Chen Yinghe's footprints that he had walked along the original road, there was no acquisition of new insights in the whole process, but only sorting out and consolidating the things that were transparent in the past one by one. This practice of not having any load on the body allows Zhang Chen to exist on this path for a long time.

Eat the heart - eat the brain - eat the bone - eat the flesh

Zhang Chen re-consolidated and reorganized the first volume of the "Phage Heart Codex" and returned to the place where he had started, but there was also a wooden door here that was exactly the same as before.

This time, Zhang Chen stepped forward without any hesitation and held the handle with his right hand and swirled it downward.

"Squeak!"

The wooden door slowly opened as the lock opened to the inside, and a silver-haired man sat inside the room, tilting his head to the back of the room as Zhang Chen entered.

With a gaze from the other party's eyes, Zhang Chen's heart, which was as steady as a thousand pounds of boulder, trembled, and the surrounding environment immediately collapsed, and the entrance to the road ended at this moment.

However, before the scene evacuated and collapsed, Zhang Chen still noticed that a relieved smile was left on the other party's resolute face.

"Could it be...... Devouring the Seniors? ”

Zhang Chen's consciousness body first woke up in the cave arranged by the evil mouth elder, and when the evil mouth old sensed Zhang Chen's change and rushed over, he stared at Zhang Chen in front of him with wide eyes, and the span of the whole person was like the span of 'nothing' in the black pyramid at the top of the Babel Tower of the Prison Continent in the prison room.

Moreover, the evil old man, as the main soul, really saw the changes in Zhang Chen's body.

In just one day, he thoroughly comprehended the 'Heart Eater', and spent a full five days to further subtly integrate the physical changes caused by the entire upper volume of the Meditation, and Zhang Chen's entire body was now as perfect as if it had been cast into a ghostly axe, with almost no flaws at all.

"Old Evil Mouth, thank you for taking care of me during this time, how long have I spent time here?"

"It's almost six days, and if you count the total time, it's just over a month. The outside world is still the same, there are no anomalies, and no one else has come to the door, I'm afraid your prison envoy's battle is still going on. ”

"It's been a month since there was any movement?"

Zhang Chen's words disappeared as soon as his consciousness fell, and Zhang Chen, who was in the center of the condensed grass and tree realm, opened his eyes.

"Whew!"

Taking a long, deep breath, the dozens of branches rooted in his body could only stay on the surface of his skin, and not even a single bit of energy could be squeezed from his body.

With his arms open, the branches of his body automatically fell off, but Zhang Chen was not in a hurry to solve all this, but quietly felt the great changes in his body, allowing his consciousness to fully accept such a perfect body as he was now.

"The Book of Body Phages is such a good thing......"

At the end of the words, because of his own free, the Grass and Tree Realm Origin Consciousness Sphere in front of him communicated with more than 10,000 of the toughest vines in the realm, intending to take tough measures against Zhang Chen.
