Demonic transformation

The system messages popped into Nicola's mind. Who then looked at the stone cave where the lion took shelter and went there. Nicola wove some simple barriers before accepting the 'Yes' system suggestion, he thought.

The process did not go fast this time, in fact it took a long time and it was very painful, since his body was being rebuilt cell by cell, his two strains were fighting within his body for its own domain. Some parts of the body constantly changed in shape, like the hands, turning into demonic claws and then changed to bestials, in a cycle that did not seem to end, all the hair fell from his body to give way to a red skin before being covered again by a newer, softer hair.

The process lasted for hours, one more tail emerged among the eight that already existed, completing the nine that a kitsune should have when it reached maturity. Nicola's muscles became bigger and denser, giving explosive power to his movements. On his head the white horns grew a little more and reached ten centimeters in height, spread around his head like a crown pointing upwards. A new power was created within himself, the power of pride sin.

[Sin of pride released] The system announced and brought a brief description.

[The sin of pride works by increasing the host's resilience and defense capabilities, with which it is possible to have a more resilient and lasting defense in future battles.]

This sin was involuntarily activated, creating a layer of black energy around his skin, that black energy was hard and looked like a shell, a tough armor that would give Nicola another layer of protection. It took Nicola's body a few hours to stabilize and complete the bloodline update.

.....

Nicola never left the base openly, every time he left he would cover himself up with powerful concealment techniques so that no enemy would discover he was not there and prevent the base from being attacked. Unfortunately for him, at that moment his tactic had the opposite effect, the enemies really wanted him to be inside.

A few hours earlier, in the secret rooms of the head of the Balta Family. "I Emanuel Balta, I call on my name and for the blood shed here the lord of the flies, Mantael, to come to me and provide me with strength for future struggles." Emanuel began to sing to invoke again his patron who was in the demonic lands.

Beside him were his son and the grandson Augusto, both had blades in their hands and passed between members of their family and cut their throats, one by one. Spilling their blood on the demonic runes etched on the floor. As the bodies were cut and blood filled the veins. A black energy gathered in the center of the magic circle, a portal opened to the demonic lands and a cloud of flies entered that room again, they circled and gathered in a whirlwind in front of Emanuel, forming the body of the demon he had called.

"Hahahahahaha! You are really a cruel man Emanuel, even the demons would have reservations about killing the blood of their own blood. Very well, you did your part of the bargain." Mantael said, the old body almost broke with laughter, of course it was just a cover for him to be underestimated. "Are you sure this is what you want?" He asked again with a sick smile, his fly eyes showed no apparent emotion, but from behind he couldn't care less about Emanuel's wishes.

The high demons were fed and strengthened by the negative and vindictive energies created by people, humans were exceptional in generating them, the vast majority of demon lords who were not on the front lines of the war were in their palaces controlling and influencing several noble families in almost all kingdoms.

This effort was a result of a much greater plan created by the Lord of the Eyes, one of the sixteen diamond cultivators known on the continent and one of the two emperors of the demonic lands.

Just like in the Melkor Empire and the Avec Kingdom. The demonic empire is ruled by two powerful diamond cultivators, The raging night which brought darkness and fear, governing the apparent sphere of the empire, commanding through strength and power. While the Lord of the Eyes took care of the underworld, it could be said that it was the brain that manipulated the whole war while the other was the muscle that went to fight.

"Yes, give us the strength to fight him!" Emanuel spoke and Augusto and his father nodded behind them. Mantael waved his hand like an attack, throwing three small objects at their bodies. Contrary to what they thought he did not hurt them. Emanuel realized that the objects were actually three small fly larvae that came into contact with his clothing and soon sank into it. Then they felt their skin being devoured by the larva and entering its flesh. The larva walked inside their bodies until it stopped near the heart, to then release a black and overwhelming power that corrupted their bodies.

Their veins turned black as they increased their power, their neck swelled with black veins running demonic magic into their blood, even their eyes their eyes became a mixture of fractal flies and human eyes before returning to the normal. But they did not complain to the demon because they felt their strength clearly increased.
