Although Gwyn's physical prowess and abilities were impressive, in Zatiel eyes they were irrelevant and what calls his attention was his body transformation and the purity and immense power of his bloodline.
'A hybrid bloodline that has reached the peak of the Emperor level and one of the Eternal Temple's body transformation techniques, to be able to train it without the temple facilities he must be pretty smart and talented but there seem to be some flaws,' Numerous thoughts pass for Zatiel's mind as he examined the Eye Holder.
Transformations on the body are very common, especially on those that follow paths similar to the Magi or races that haven't inherently powerful physiques.
Most of these transformations focus on implanting organs of different creatures or special magic object but they don't have a systematic method of advancement and at most, they give a momentary burst on power until you advance into the next Rank.
There are also dangers by performing this type of transformations, as it could contaminate your body if the processing of the organs or magic object is not handled perfectly.
Despite all that, the number of individuals that perform this type of transformation on their body is not small, after all, the races or paths that can improve the energy, soul, and body of an individual in a synergic way are pitiful on the universe.
Of course, there are body transformation techniques that can systematically alter the body and the improvement they give do not enter in conflict with your bloodline or main path, but even if you don't take into account the difficulty to obtain them, most of them require the use of the laws in the transformation of the body.
No matter how much of a genius you are, it is only at the peak of Rank 3 when a life form's soul is powerful enough to start understanding the laws, so to train this type of body transformation techniques you will normally have to use special facilities or the help of a powerhouse that specializes in the use of the laws that the technique uses.
But there are other ways of using the laws without the need of a powerful soul, such as the help provided by a Law Bloodline or your True Name, and Gwyn seems to be able to use the latter to advance.
The body transformation technique that Gwyn use, is part of the techniques created by the Eternal Temple.
The Eternal Temple was a powerful and extremely old organization in the universe, with several Being of Laws as members and an even more powerful existence as the leader.
Zatiel had an encounter with this organization when he was an Abyss Lord, although calling it an encounter was wrong since what happened was that he found a stronghold of the Eternal Temple and kill everybody in it, stole their spells, techniques, and treasures before escaping.
Although the Eternal Temple was known for their vengeful ways, when that happen Zatiel had already achieved a Rank higher than normal Being of Laws and by staying in the layers of the Abyss dominated by him, there was nothing the temple could do.
What Gwyn was training was the Eternal Vengeful Body, one of the temple core techniques and although it don't provide stunning offensive capabilities, its survival abilities were impressive and if one was able to train it to the sixth level, you could achieve eternal life, even if you don't become a Being of Laws.
The Eternal Vengeful Body is indeed impressive, but Zatiel would not train it, after all, a Neo-Demon's body transformation is even better since it uses Elemental Chaos as the main material and that improvement was even more significant when it advance to Rank 4.
As Zatiel was evaluating the Eye Holder, the latter was doing the same to the Neo-Demon.
But unlike Zatiel's calm and analytic expression, on Gwyn's face, there was frustration.
'Why I can not see anything?' Gwyn knitted his brow as he saw Zatiel and wasn't able to detect anything.
His bloodline was related to the spirit, and his True Name was even more special as it gave him the ability to detect the other party feeling and intention generated from their soul.
Although it was not very specific and it was more similar to an instinct, thanks to it was that Gwyn was able to survive this long despite being the target of animosity of a Soul Forging individual.
Eventually, Gwyn broke the silence.
"So you are Zatiel Daybreak, I am Gwyn Xinter, member of the Ghost Eye clan. I had heard tales of your battle power and you are even more impressive in person, but if I have not helped you then Azel would have escaped, so I guess you owe me a favor," Gwyn expression was amicable and friendly as he spoke.
Although the dead of Azel brings him great satisfaction, he did not reveal his relation, so he could take advantage of this opportunity to obtain Zatiel's favor, after all, the help of a powerful runemaster was very useful to him.
Kira, Sophia, and Ezequiel were flying to Zatiel's side and as they did, they focus on the other party and were vigilant.
Although Gwyn had helped them and it seems he had some problem with Azel from before, they know that an enemy from my enemy is just a party with similar interests, that could become an opponent in the next moment.
And now that Gwyn was mentioning a favor, the trio knew the situation was becoming tricky as most people on the Magi World like to use the philosophy of equivalent exchange, and although they could not be forced to repay if word gets out their future transaction could become affected.
But unlike the trio, Zatiel expression remained calm, and a funny expression could be seen on his face as if he was watching a child try to argue with an adult and shook his head before speaking.
"Point one, although you only showed for a moment and then try to hide it, your hate for that person was so deep that has taken root in your soul."
When Gwyn hears this, his expression changed from a friendly to an indifferent one, but Zatiel doesn't care and continues speaking.
"To hate someone so much, he must have to do something unforgivable. Maybe he stole a precious treasure, rape your partner, kill your parents..."
Zatiel has been watching Gwyn's expression the entire time, and when he mentioned his family, his eye becomes cold but there was also a flash of sadness in them.
"So your parents, then taking into consideration this information, we help each other so no one owns anything to the other party." Zatiel voice was calm and indifferent as he spoke.
But when Gwyn hears him, his eyes become colder and a wave of killing intent was released from his body.
"You should be more careful when you mention some else's family," Gwyn's voice was chilling as he stares at the four people in from of him.
Despite being one against four, Gwyn shows no fear and the killing intent around him only grown and neither Sophia, Ezequiel or Kira were confident in their chances since both Zatiel and Ezequiel were badly injured and the two women were exhausted.
Despite being the party targeted by Gwyn killing intent, Zatiel remained calm and continue speaking,
"Point two, your body transformation is flawed and you can only maintain it during a brief period of time thanks to the vitality runes inscribed in you and it seems that you have spent a long amount of energy already. So according to my calculations, you can barely maintain your power by a couple of minutes more."
"So you better behave or else, we will retain you here until you are exhausted and then I will eat your brain while you are alive just like I did with that woman," Zatiel expression remained indifferent but his eyes become cold and as he spoke a monstrous killing intent was released from his body.
If Gwyn killing intent was like a river, then Zatiel was an ocean formed with the blood of billions of lives, something capable of forming only in someone who can erase the life on a planet without second thoughts.
It was so brutal and terrifying, that Kira was startled and begun to tremble just because she was close to Zatiel, and although Gwyn had lived a hard and cruel life, he still froze for a second.
After a moment, Gwyn retracted his killing intent but still, his eyes were cold as he continues looking at Zatiel.
"That is better, now let's go to the third point. The piece of fallen star that you are hiding in your stomach has an impressive amount of energy, give it to me and I will fix your body"
