Lin Chen, a history college student, accidentally traveled to a Tang Dynasty bronze mirror in a museum and traveled to the Wu Dynasty, which was similar to Wu Zetian's reign. He became a poor scholar in Chang'an City whose parents died and made a living by copying books. This is not the history he is familiar with, but a fantasy world where monks from the three sects of Confucianism, Taoism, and Demonology stand side by side, and monsters are watching eagerly. The Confucianists follow their words with awe-inspiring righteousness, the Taoists rely on true energy to refine elixirs and set up formations, and the demonic path relies on demonic energy to devour and plunder. The monsters in the hundreds of thousands of miasma forests in the southern border are even more compressed due to their living space, frequently setting off waves of monsters on the border.
