Fixten

In a world where summoners wield the power to call forth vampires, elves, angels, demons, and all humanoid creatures from across the realms, Nathan found himself unable to summon beings except from beasts. 

However, those beasts are not ordinary beasts. They are divine beings who once stood at the same level, if not higher, than the legendary creatures the world ever knew. 

Casting his gaze to the left, Nathan sees numerous summoners accompanied by the likes of demon kings, archangels, vampire progenitors, and other legendary beings. Turning to the right, a massive army of alien symbiotes is waiting to attack. 

There was no fear in his eyes, because standing on his left is a majestic wolf who managed to kill a god, the legendary eight-headed serpent coils on his right, above him is the bird who is glowing like the sun, and behind him is a dragon that once gnawed the roots of the world tree. 

“Let the war begin.”

"What did you say?!" Charlotte looked shocked but soon calmed down. "No, wait. You're able to alter the world's record by using the Soul Contract, so changing one's skill is not impossible. I shouldn't be too shocked from this…"

Nathan nodded. "There is one thing that piques my curiosity, though."

"The Soul Contract seems to be able to evolve further. It has evolved once, allowing me to utilize the contract even more efficiently. So, once I reach a certain threshold, I might be able to evolve it once more."

"!!!" Charlotte's expression turned grim. There was no research about the innate ability, so she didn't know if an innate ability could be evolved or not. She stood up and hurriedly grabbed a notebook. "Let me record that first. An evolution for an innate ability… The potential of further evolution. Is this the norm? Hmm. Without enough data, I can't really draw a conclusion.
