"Fei Yan, drink this!" Abel said to Fei Yan after taking out a bottle of 'soul potion' and opening it.

In fact, there is no need for Abel to say, when he took out the 'soul potion', Fei Yan was already waiting with his mouth wide open, but it knew the benefits of this elixir to it, since he drank a bottle, Abel had not given it again, and now he was naturally a little impatient.

A bottle of 'soul potion' was poured into Fei Yan's mouth, Fei Yan's eyes were a little hollow, and the gray scale armor on his body was darker, and after just thirty seconds, Abel found that Fei Yan had recovered, and the effect of the 'soul potion' had passed.

Abel took out another bottle of 'soul potion', opened the cap, and poured the purple liquid into Fei Yan's mouth, although he didn't know how many bottles it would take to change, but there were as many as thirty bottles of 'soul potion' in Abel's empty ethereal beast bag, because he was in the black wasteland, there were a large number of hellish creatures, the source of the 'soul potion' was very convenient, as long as it could strengthen Fei Yan's combat power, the consumed 'soul potion' could be replenished quickly.

The second bottle of 'Soul Elixir' was fully absorbed in another thirty seconds, and it was still a very slight change, and the color of the gray scale armor deepened a little.

The third bottle of 'Soul Elixir', the fourth bottle of 'Soul Elixir', the fifth bottle of 'Soul Elixir', until the tenth bottle of 'Soul Elixir' was poured into Feiyan's mouth, and the tenth bottle of 'Soul Elixir' made Feiyan's whole body tremble, and it lowered its body and made a curling motion on the ground, placing its head in the body circle, its tail curled to protect its head, and its wings released to completely envelop its body.

A strong coercion emanated from Feiyan's body, which was bent into a ball, and the coercion it exuded this time was much stronger than the coercion it emitted when the dragon roared in the air, and even Abel's summons, who were already very familiar with it and began to be somewhat immune to coercion, all bowed down at this time, and did not dare to move.

Black Wind also seemed to be affected, but as a wolf beast king, it did not bow down, but instead stood up with hair all over its body and made a vigilant posture.

Abel was the most insensitive, although he couldn't emit dragon power, but his soul was integrated with the dragon power of a giant dragon, so he casually observed the changes in Fei Yan's body.

Ten bottles of 'soul elixir' made Fei Yan have a change in promotion, and Bai Yun, who had a huge body, only used five bottles of 'soul elixir', which also showed that Fei Yan's body was different from each other, and the strength of the dragon clan was equally powerful both in body and soul.

At this time, Fei Yan's whole body was trembling violently, and there seemed to be a strong pain stimulating it, Abel saw this situation, and hurriedly transmitted his perception through the soul chain, and a pain like pulling bones and peeling skin came from Fei Yan's soul.

Although the pain that only passed through the soul did not come from Able himself, the pain that came from the soul was clearer than the pain from himself, and his body began to twitch, and now as soon as he broke the soul chain, the pain would disappear.

But Abel gave up the idea of breaking the soul chain as long as he thought that Fei Yan was suffering from more intense pain than this, and he forcibly resisted the pain, although this pain had made him unable to control his body, but his soul could still transmit messages.

A message of understanding and comfort was transmitted to Fei Yan's soul, although the master's actions did not really reduce the pain, but the master's behavior of bearing the pain with it made Fei Yan's body slowly stop trembling, as if a belief and a power were being restored in its body, and the body that was originally bent because of helplessness was slowly relaxed.

Although the dragon clan is the darling of heaven and earth, the world is always seeking a balance, strong strength and strong body in exchange for low fertility, and the difficulty of promotion has also increased countless times, and the risk in promotion is also the highest among all creatures.

Fei Yan's age is still very young, although the 'soul elixir' has made up for all the conditions it needs for promotion, whether it is physical or spiritual, but it can't make up for its psychological loopholes, it lost its mother's love when it was young, and lived alone in the dragon clan, so that it has no psychological support.

The pain during the promotion almost made it lose the courage to live, but at this time, the intervention of Abel's soul and the experience of the master sharing weal and sorrow with it made it once again give rise to hope for life, and as long as it made up for the defects in the soul, the 'soul potion' had made up for all the other conditions.

This is where the 'soul potion' is powerful, the 'soul potion' strengthens the body from the soul source, this enhancement method is different from all other enhancements, the soul is the most mysterious, and any change may lead to unaware consequences, so the study of the soul is the most difficult research direction for all wizards to access.

And even if there is this kind of research, and there is a divine help to research the 'soul potion', there must be so many souls to provide, why the Hradic cube does not absorb the souls of all creatures in the Holy Continent, it is because the soul strength does not meet the requirements.

There is no place where the study of the soul is as profound as hell, only the soul that has been transformed by hell is the only material for the 'soul potion', and hundreds of hell souls are synthesized into a bottle of 'soul potion', and the nourishing effect of such an elixir on the soul can be imagined.

Slowly an hour passed, Abel was not as good as just now, the convulsions of his body weakened a lot, although the pain was still so intense, but the most strange thing about human beings is the ability to adapt, this pain has been slowly adapted to him during this time, and the body has been able to bear this pain.

This is a very rare experience, you must know that if this experience occurs in oneself, basically the body has been broken to a very serious extent, but the pain transmitted through the soul chain is only a pain on the soul, and has nothing to do with the body, as long as this pain can be survived, the only effect is that the body's tolerance for pain will be greatly improved.

Of course, Abel didn't have this kind of experience at this time, he was still constantly comforting Fei Yan, Fei Yan suddenly let out a miserable scream, and a pain that was several times stronger than the pain just now came, and this pain almost made Abel's body protect itself, but fortunately, this pain just disappeared at once.

At this time, there was already a trace of blood in Abel's mouth, it was the sharp pain just now that made him bite through the skin in his mouth, but he didn't have time to care about it anymore at this time, he was surprised to find that at the top of Feiyan's pair of wings, a pair of claws appeared.

The reason why the bipedal wyvern is called a bipedal wyvern is because it only has a pair of claws, and only the dragon has four claws, although the new claws of Feiyan are completely different from the thick claws that the dragon grows under the body, but this does not prevent Feiyan from changing from a bipedal wyvern to a four-legged wyvern, or a two-legged and two-clawed wyvern.

The promotion continued, but the pain had basically disappeared, and all Abel felt was the comfort brought by the continuous enhancement of Fei Yan's body, and in what he saw with his eyes, Fei Yan's original scale armor fell off piece by piece, and where the scale armor fell off, pieces of scale armor slowly emerged from under the skin.

These scale armor were already completely pitch black, the color of the night, and it only took a few dozen minutes to go from being soft at the beginning to finally becoming a hard scale armor that adhered to Fei Yan's whole body.

On Fei Yan's four claws, the sharp claw tips are constantly growing, and the original white is turning into blood red, just by looking at the color of the claws, you can feel that there is a huge power contained in them.

Finally, there was a burst of excitement in Fei Yan's soul, and Abel shared the joy of promotion with it at the same time, Fei Yan stood up from the ground, and his new body made it a little unaccustomed, especially the two hand-like claws on the tips of the newly added wings.

But instinct has made it familiar with it for a while, and it has been able to use its front paws with ease, as a dragon, it naturally knows what the four-legged represents, and at the same time, it also knows that it is the master who has suffered greatly with it in the most dangerous times, which has enabled it to successfully advance to become a four-legged wyvern.
