I Come from Spring and Autumn Period

At the end of Chaoge Shen Lane in Weiguo, there is a dilapidated Yuan Library. Deng Qu, a blacksmith apprentice, studied here for three years. Before leaving, the gentleman whose origin was a mystery threw him a jade plaque. When he came back twenty years later, his hair was gray. This time, he finally stepped onto the stairs leading to the second floor. Pushing open the door, Deng Qu found that he had traveled to a completely different world - the monks who escaped from the sky, the sect where the weak preyed on the strong, and the ancient secret realm hidden in the mountains. The only thing he relied on was the jade plaque given by his husband. He doesn't know who his husband is, the origin of the jade plaque, or whether this time travel is a coincidence or a game of chess that has been played for three years. All he knew was that if he wanted to survive, he had to climb to the top step by step and ask for answers.
