When he woke up, Li Yang found that everything had changed. Different identities, different time and space, everything was like a dream.
He had been an emperor, could decide life and death with one word, and had a harem of three thousand beauties.
If you have been a student, you can read thousands of volumes of poems by saints, and you can be on the gold list.
Having been a knight, I can travel thousands of miles with my sword and eliminate evil spirits and monsters.
...
In the end it was just a big dream.
