When Lin Yanzhi woke up from a strange old house for the first time, he thought it was just a ridiculous nightmare - the carved wooden windows reflected the strange crescent moon, the bronze mirror reflected the young man in green shirt whom he had never met before, and the fragrance of ink that did not belong to him was still lingering on his fingertips. But when he woke up in the same "dream" for the third and fifth time, looking at the familiar carved bed curtains and listening to the repeated beating of drums outside the courtyard, he finally realized something was wrong: this was not his dream.
In the dream, he is Shen Yan, a scholar from a poor family, who has to deal with the open and secret attacks of the court factions, and also solve the mystery of the "accidental" death of his mentor; in reality, he is a newly graduated history student, and the fragments of ancient scrolls he saw in his dream always appear on his desk for no reason. What's even more bizarre is that every time he makes a key choice in his "dream", unexplainable changes will happen in reality - the pages of ancient books on the bookshelf automatically turn, strange encrypted documents suddenly pop up on the computer, and someone even knocks on his door late at night and reads a code word that only "Shen Yan" understands.
He began to frantically search for connections between the two worlds: Why was Shen Yan's handwriting exactly the same as his grandfather's diary? The bronze talisman that appeared repeatedly in the dream was actually hidden in the cellar of his old house? When he tried to uncover the truth about "who dragged him into this dream," he discovered that "Shen Yan" seemed to be peeking into his life through dreams, and the boundaries between the two souls gradually blurred.
