The Gate of Yicheng

The oldest door in the world. No one knows what lies beyond it. The Empire officially calls it an ancient ruin. Scientists say it is an energy node. The millions of people in Yicheng say it is the aurora mentioned in the weather forecast.

Only a handful know the truth: the door is cracking. The seal is loosening. Whatever lies beyond it is about to emerge.

Shi Su knows. The secret he has kept hidden for over a decade is tied to this door. Born with two contracted spirits, his first is Time, and his second is Spirit Contract: a plunder-type power, unique in all creation. But he dares not use it. If his secret is exposed, every faction will hunt him down.

Then, on the day a crack appeared in the door, he met another person with two contracted spirits: a girl who was also hiding her abilities and resisting the path laid out for her. On their wrists, one black mark and one silver mark lit up at the same time.

Twins are the key, time is the lock, and Spirit Contract is the keyhole. When all three keys are gathered, the door can be opened.

Beyond the door, a gray-eyed man has already been waiting for twenty years. He is no good man. He does not care what becomes of the world outside. He only wants to tear down the door and reunite the two worlds.

Seven days. There are only seven days before the door opens.
