Making Genetic Potions, I Control Nine Cities Behind the Scenes

[Villain + fusion gene + cult leader + behind the scenes + no heroine] Qin Sheng was transported through time and luckily survived, but his life span was less than a year. Fortunately, the time traveler was bound to him with the system, and he was able to extract and fuse the genes of alien beasts to create various potions. Although in this era where alien beasts have been invaded for hundreds of years and humans have been forced to build nine cities, the genes of alien beasts are taboo. But in order to survive, he could only create potions one after another and fuse the genes of alien beasts. Unconsciously, Qin Sheng became the most terrifying cult boss in human history! And at first he just wanted to heal himself.
