Song of the Celestial Calendar

Anti-routine time travel, no system, no portable grandfather, the golden finger is almost negligible. The other world has been cut through a sieve by the senior time travellers, and all classic traveler routines such as copying books and soaps have been cut off! What's even more frightening is that there are monsters and supernatural powers in this world. Facing the beginning of hell, the only thing the time traveler Chen Ming can rely on is wisdom! A grand world view, rich details, delicate emotions, and endless suspense.
