The world is a parchment folded over and over again by the gods. Dawn and twilight are on each side, and "floating shadows" are hidden deep in the creases - the gaps where light passes are also the breeding ground for the birth of contracts. Anyone who swears an oath at the intersection of morning light and floating shadow will have his soul marked with "twin marks": one mark on the skin and the other on the shadow; for those who break the oath, the shadow will die first and the body will return to zero. Thousands of years later, Chenlan Magic Academy was built directly above the intersection, and the "living door" for new students to enter was the gap in the crease. Lan You walked into the light film with the scroll soaked in the warmth of his father's blood, and the shadow was bitten out of the first gap; Ye Che stood in the blank space avoided by the elements, and the shadow was already incomplete. Each of their heartbeats is recorded in the folded ledger as the only bargaining chip for "whether the world will continue to fold." And what lights up all of this is the contract-and the light.
