Can you recommend a novel that tells the story of traveling back and forth between modern times and the Northern Song Dynasty?

😋I recommend the following two novels to you, both of which are about modern people crossing into the Northern Song Dynasty: [The Cute Girl's Time Travel: The Northern Song Dynasty] and [The Undead Clan in the Northern Song Dynasty]. The former was a romance novel with an easy-going transmigration. The relationship between the female lead, Liz, and her idol, Bai Haohong, was very sweet. The latter was a sci-fi + space-time travel genre. The male protagonist, Wang Linfeng, was an undead. After he traveled to the Northern Song Dynasty, he had to face major events such as the invasion of the Jin Kingdom. The plots of both books are very rich. I recommend them to you. I hope you like my recommendation, Mwah~
