Twins with the same root, twin stars in life.
The elder sister inherits the aura of the day, and with the sunlight on her body, her magic power is at its peak; the younger sister enjoys the clear light of the moon at night, and can only see things at night, and her spiritual power awakens with the night. The two of them are one body and two souls, linked by destiny. A jade pendant handed down from ancient times is a contract, which can lead the souls to converge and the twin stars to merge, bursting out world-shaking spiritual power.
Day and night complement each other, light and shadow depend on each other. The road to immortality was twists and turns, fate was entangled, they walked hand in hand through the waves of earthly fate, using the jade pendant as an alliance, and taking the morning and evening as their lives, day and night, the two shadows walked together, and finally became the unique pair of morning and evening lights in the world.
Purpose: Twins complement each other and one cannot exist without the other. Incompleteness is also destiny, and bondage is better than destiny.
