Duan Fei, who had been flying for nearly four hours, stopped again to rest for a while, and landed on a hillside that was not too big or small, Duan Fei took out the memory key fragment from his clothes and played with it carefully, Duan Fei had never seen the appearance of a high-level evolutionary like Fengya when he used the evolution power, but he could feel the evolution power of where and who it came from.

Every advanced evolutionary who has an evolution key fragment or a full version of the evolution key will come with a trait of their own when using the evolution power, this trait is very faint but makes you feel a little different, just like the color, red seems to be a monochrome, in fact, it includes a lot of other 'red', such as dull red, light red, rose red, water red, magenta, etc., the essence of these colors is red, but it has its own difference, just like the evolution key fragments, If it is a pure evolution key, it has been eliminated by the user by means of all its own traits in the era of the ancient gods, and it has been restored to its original appearance, just like the evolution key slate that Fengya encountered on the paradise island.

For example, a fire-based B-class awakened person has been infused with the evolutionary power of a high-level evolutionary, and when the ability successfully evolves into an A-rank, he may be biased towards the blazing flame of endless heat, and at the same time, it may be a blazing flame that is biased towards defense, and part of the possibility depends on the mind of the high-level evolutionary who gave evolutionary power.

An important reason for the emergence of this phenomenon is that the evolutionary force carries a part of the host's memory in the process of transferring, and this memory characteristic does not include the so-called record of the past, and a kind of general direction of what the evolved person should become in his mind at the moment before the evolutionary force is released.

Memory is the reflection of past experiences in the mind. The so-called past experience refers to the perception of past things, thinking about problems, experiencing emotions caused by a certain event, and performing actions and operations. These experiences can be stored in the brain in the form of impressions, and under certain conditions, these impressions can be extracted from the brain, and this process is memory.

It is the psychological function of information about stimuli, events, images, concepts, etc., which is maintained when the original stimulus no longer exists, and it is the recognition, retention, recall, or recognition of an individual's experience.

From the perspective of information processing, memory is the encoding, storage, and retrieval of information. What has been perceived, thought, experienced, and acted upon can become an individual's experience. For example, if we see someone we have seen before, but now we are not in front of us, we can remember his posture and appearance, and we can recognize him when we see him, which is memory.

Memory is an active process, and recognition, retention, recall, and recognition all have this characteristic. Recognition and memorization is the initial stage of memory, and it is the memory process of acquiring knowledge and experience. Recognition is selective. Stimuli in the environment can only be recognized if they are noticed by the individual.

The laws of the memory process are recognition, retention, rerecognition, recall, and forgetting. Memorization refers to the encoding, organization, and storage of learning materials in memory systems; Retention refers to keeping things in the brain for a certain amount of time; Recognition and recall are both forms of information extraction from memory, and recognition refers to the fact that when the perceived thing reappears in front of the eye, it can still be represented.

It turned out that the mermaid mutant beast had exhausted all its evolutionary power and turned into a fragment of the evolution key of a pitch-black stone, but at this time it had regained its luster and received energy replenishment from the same source, and this stone tablet had regained its strength, and each ability would consume the human body, taking Duan Fei as an example, his most powerful and explosive Hellfire ability, in the case of using the ability, it consumed three times more life energy than the prokarcore ability, In other words, every time Duan Fei sent out a hellfire bomb, he could use the equivalent of three pronuclear balls.

Of course, even the evolution key will consume the human body, but the premise of this consumption is that there must be enough evolutionary power in the evolution key tablet for evolution, and in the case of sufficient former, a small part of the user's life energy will be consumed to act as a 'transfer boat', so that it can bring the evolutionary power to the evolutionary.

If it was someone else, when he first came into contact with the evolution key slate, he didn't have such a big reaction as Duan Fei now, and the moment he touched the slate, the soul that was still in his body split into a part and transferred to the slate in an instant.

The evolution tree in his body also quietly transformed into a phantom after Duan Fei's 'soul went out of his body', appearing behind Duan Fei at a height of three meters.

There was a dark connection between the Evolution Tree and the Evolution Key Fragment, which were also super ancient objects, and when Duan Fei came into contact with the fragment to activate it, the sleeping evolution was suddenly stimulated, and the dark resonance between the two split Duan Fei's soul, and some of it was sucked into the fragmented stone.

Duan Fei's body outside was stagnant because he couldn't accept the split soul for a while, and the whole person looked at the front blankly, sitting here quietly with the stone slab in both hands, fortunately, the zombies and mutant beasts nearby had already been cleared, because Duan Fei was almost relaxed and unguarded at this time.

On the inside, it was just the opposite, and a part of Duan Fei's split soul was circling inside the Evolution Key Stone Tablet. The middle of the fragment was pitch black, like a black hole, but in the middle of the black hole was a pale blue ball engraved with strange symbols.

Duan Fei's soul slowly floated over, his hands touched the edge of the earth-like sphere, and with a buzzing sound, a symbol on the ball suddenly lit up with a red light, which was extra dazzling on the all-blue ball.

The red symbol slowly floated up into the air, and then slowly became larger into a canvas, Duan Fei, who took a closer look, suddenly looked surprised, only to see that this big red symbol was also composed of countless dense small symbols, and these small symbols were different from those on the blue ball, but more like some words that had disappeared for a long time.

"What?" Even if he squinted, Duan Fei couldn't understand what was written on it at all. However, Duan Fei was wondering why the soul would split apart for no reason and enter the evolution key stone slab.

The big red symbols scattered with a bang, and the small text symbols were regularly distributed in front of Duan Fei to form a painting wall.
