Da Qin: I Help My Father-In-Law Ying Zheng Conquer the World

[Da Qin + fantasy + harem + resourcefulness + saucy words + slang + imagination] I am Li Fei. When I woke up, I found that I had traveled to the Qin Dynasty. What? No system? Don't panic, Li Xin is my clan uncle, Ying Zheng Wang Wan is my father-in-law, and hundreds of schools of thought regard me as an immortal! You mean cultivation? Don't be in a hurry, practice martial arts and literature, and copy the literary spirit. Wow, you can actually summon the Great Demon of the Nine Realms? It's a pity my friend, times have changed, and the boy is going to be on fire. Japanese country? What's going on? How could there be a Japanese state in the Qin Dynasty? The secret of the three artifacts? The weight of the imperial seal? The resonance of Demon Sword Muramasa? What is the secret of this world... My story is waiting for you to explore. Follow me to assist my father-in-law, and let your eyes see the land of Qin!
