After their peaceful lives in the northern province passed, the immortal-like young man finally stops holding his ascension back as his dear little sister is also now ascending to celestialhood as well, a terrifying pillar of light that brings about auspicious signs that covers not only the entire planet, but also the entire star system they are in appearing as the two of them break through the constraints of the mortal world they are in at the same time, the two of them celebrating this by sharing a passionate kiss as they float around in space.
After this scene, Su Xiaotian's vision turns black as he finds himself in an empty white space, only realizing now that these are not only visions or some other kind what if illusion, but a memory he truly has, something he had experienced and not at the same time.
