Have you recommended a novel where the main character's surname is Wu, and his name might be Wu Jie? After being struck by lightning, he would be in the modern world during the day and travel to the ancient world at night?

Looking for a novel, the main character's surname is Wu, I think his name is Wu Jie? After being struck by lightning, he would be in the modern world during the day and travel back to ancient times at night. He worked in the library during the day and traveled to ancient times at night. He used to be a fool, but he became normal after he possessed him. After his parents died, he returned to his hometown in Chengdu. When he was young, he was engaged. When he returned home, he came to break off the engagement. During the day, he wrote the Four Books, Five Classics, and Eight-legged Essay in the library into Pinyin. At night, he traveled to ancient times to take the imperial examination! I didn't read the rest of the novel. I just read it yesterday, and I wrote 950,000 words! There was a maid who was very fierce to him, but she was dead set on him!
