Starting from the Black Snake, Build a Kingdom of Monsters

Jiang Ze traveled to the world of demon cultivators and became a huge, extremely venomous black snake. He just wants to practice his duties and realize the immortal way as soon as possible. Helplessly, the demon clan is cruel and preys on the weak. Only the strongest deserve to survive. The system comes in time, and as long as you accept the demon cultivator as your vassal, you can get a bloodline improvement. From [Crossing the Mountain Peak] to [Ink-armored Poisonous Dragon], every scale and claw contains the supreme power of the dragon. From [Snake Venom Extract] to [Withering Plague], it is enough to level the mountains and streams without taking any action. Ping Sifang Immortal King, who said that the demon clan has no great emperor? Armed with millions of demon soldiers, established a national title, the demon clan... Can also live in the court.
