The world is swallowed up by boundless darkness, order collapses, and all creatures perish. Eternal night is approaching and everything will be extinguished.
Lin Chen and Su Qingyao, one bright and one dark, one strong and one soft, use their mortal bodies to fight against the source of darkness, stick to their faith in despair, split the sky at the end of the eternal night, and restore light and new life to the broken world.
The core of one sentence:
Break the eternal night with two hearts, exchange the dim light for the bright light.
