System Bestows me with Immortality, Living on to Eventually Become Invincible

The divine light gradually dissipated, and a figure slowly stepped out from mid-air, exuding an aura of nobility.

The figure's heterochromatic eyes gradually turned to a normal black, yet they remained clear and bright, sparkling like stars. She wore a black long dress, her long hair gently draped over her shoulders, her skin smooth and soft like warm jade, her beauty as delicate as a willow.

However, her figure was like that of a ten-year-old child. A little girl?!

Black Bull and Little Chi were shocked for eight hundred years. The Little Crane they had raised for so long turned out to be a ten-year-old girl?! Wasn't she supposed to be a boy?!

Her cheeks flushed, she suddenly smiled slightly, her eyes curved like crescent moons, as if the spirit within her overflowed.

In her every move, that noble demeanor naturally revealed itself, making them marvel at her elegant and spiritual radiance.

She nervously pinched her dress, softly calling out, "Big Brother... Second Brother... Fourth Brother."

"What the hell!!!"

At this moment, an untimely angry voice rang out from below, "Little Crane, how the hell are you a child?! How dare you!"

Little Crane was instantly overwhelmed by the shout, tears welling up in her eyes. She feared her big brother the most, who always told her terrifying things.

The Crane Spirit Yin Yang Tree, unique in heaven and earth, was created by Chen Xun. The world has two sides, Yin and Yang, and so do living beings. He and Black Bull had infused the World Soul, carrying their abundant Yang energy.

If she were to take form, she must absorb the legendary boundary origin, using this opportunity to merge Yin and Yang, breaking through her million-year shackles, or else she would wither and fade with time, unable to advance.

As for why her true form could absorb the boundary origin, it seemed to be an innate talent of her species... Chen Xun didn't know, and neither did she...

"Crane... Brother... Crane Sister?!" Little Chi's lips trembled, bewildered that she was female, having always called her Crane Brother!

"Moo moo!" Black Bull rushed up, rubbing against Little Crane, quickly placing her on its back, eyes filled with excitement. It didn't care about race or gender; family was family.

Little Chi stood nervously beside Little Crane, observing her closely, equally excited. Crane Sister always took care of him!

Little Crane's eyes were pure and innocent, knowing nothing. All her knowledge came from her big brother, as she quietly sat sideways on Black Bull's back, looking worriedly at her big brother.

"Big Brother, I've absorbed the boundary origin, weakening its power by three parts. There must be a path below!"

Little Crane timidly called out, quickly holding onto Black Bull, "I... I won't cause you any trouble!"

"Little Crane, protect yourself. Brothers, follow me and charge!"

"Moo moo~~!"

"Xun, we believe in you!"
