Ultra: Rebirth of Belial and Picked up the Dark Circle

[System] + [Single Female Protagonist] + [Decisive Killing] + [Invincible in the Early Stage] The protagonist Gu Yang was sent alive to another world by Universiade just because he saved a little girl. The soul did not die, but traveled through time and space and was reborn in the most dangerous moment of the Ultra Universe - Beria, who had just been possessed by the soul of the Reblondo star and was on the verge of madness and pain! Before he can adapt to this body with destructive power, he has to fight against the pursuit of the Kingdom of Light's highest combat power. In a desperate situation, the [Dark Circle System] awakens, giving him unlimited energy and summoning power. From then on, a "Belia" with modern thinking, and a system that was invincible at the beginning, was forced to embark on the road of fighting the enemy, struggling to survive in the dark abyss, and trying to establish a galactic empire.
