Xin Yan, a doctor of archeology, traveled through time and became a Mayan sacrifice, and was rescued from the knife by a slave girl who had her tongue cut off. After accidentally eating spiritual grass, he awakened to deduce the golden finger - every time he comes into contact with ancient objects, he can foresee the consequences for three days. He became a god by predicting solar eclipses, farmed with geometry, and climbed to the top of power step by step. But it was discovered that the prosperity of this city originated from a space-time rift that fed the old gods. The high priest made crazy sacrifices to delay the end. And his own time travel was actually the human consciousness split from the old gods. When the deducer displayed the final option: awaken the gods, or become a new god - Xin Yan stood on the altar and smiled.
