Ling Che is an eternal observer stuck in the gap of time. He has no beginning and no end, is helpless, takes the form of consciousness, and sees all the inevitability of all timelines - witness the hesitation of the First Emperor's fingertips hanging on the bamboo slips, experience the brutal impact of meteorites in the Cretaceous, and listen to the moment when a poem is born on the other side of the galaxy. He is like an observation instrument that never stops. He can see the precise operation of the universe, but he cannot touch it, intervene in it, or even close his eyes and escape.
For trillions of years, the birth and death, light, sound, and cause and effect of countless timelines were overloaded in his consciousness, and his divinity was crushed to the point of collapse. His pain was never loneliness, but the suffocation imprisoned by "perfect necessity" until, on an ordinary time branch, the little girl Lin Xiaoman wrote down an incorrect answer to an arithmetic problem. This faint unexpected ripple became Ling Che's only light in trillions of years.
In order to protect this lovely imperfection, Ling Che broke the indifference of the observer, exhausted his divinity, and paranoidly guarded every mistake and ignorance in Lin Xiaoman's growth. But the strict rules of the universe do not allow for surprises. The pursuers of the rule enforcers, the foreshadowing of the time disaster hundreds of millions of years ago, and the mysterious forces outside the universe follow one after another.
Ling Che is no longer an indifferent bystander. He awakens the ability to intervene, forms an alliance with his former opponents, fights against the crushing rules of the universe, and reveals the truth about the time disaster. A battle involving perfection and imperfection, observation and protection, divinity and redemption begins. Ling Che bets his divinity for trillions of years just to keep the glimmer of light that illuminates the gap in his time. The secrets hidden deep in time are slowly coming to the surface with his protection.
