The Baiyu people enjoy a thousand-year lifespan, but the price is that every hundred years they have to hold the "Tonghui Stone" with someone who is connected to their hearts and cross the Holy Land Waterfall before they can both fall asleep and be reborn. If you are alone, your life will end within the next hundred years.
Wu Yunshu stood in front of the waterfall for the tenth time. The first nine failures put her life on a countdown. Driven by her survival instinct, she selected Wang Lujian, an 18-year-old boy with clear eyes who was participating for the first time.
When the two stones touched, a blazing light that had not been seen in the Holy Land for thousands of years erupted. The contract is reached and the crisis is temporarily resolved.
However, the light awakens the sleeping ancient secrets. They discovered that this "congenial contract" was not a God-given marriage, but a destiny script that had been written for thousands of years - their love was the most perfect and cruel link in maintaining the operation of the entire immortality system.
