Cangyuan: from Killing Demons to Raising Demons

[Cool article] + [Single female protagonist] + [Soul penetration] + [Upgrade flow] + [Invincible] + [Cool to the end] Meng Chuan traveled to the world of Cangyuan. On the day Meng Chuan was born, his father's laughter was still in his ears, but the demonic disaster in the future was already looming before his eyes. He knew that Dongning would bleed, that his relatives would suffer, and that the human race would be suppressed by the demon race for too long. On the night of his birth, a drop of demon blood was sent to the Meng family. Meng Chuan awakened the demon-devouring system, and after swallowing the demon blood, the baby's body began to transform. From then on, he swallowed demon blood to refine his body, seize the secret skills of the demon clan, and refine the demon soul to strengthen his god. Others practiced hard for ten years, but he swallowed blood in one night and broke through; when others saw the demon retreating, he took the initiative to go out of the city to kill. The demon clan in Dongning Mansion attacked, and the whole city was panicked. Meng Chuan went out with his sword in hand, killed the Demon King with one strike, and drew blood on the spot, which shocked everyone speechless. Later, the demon clan finally understood that the invasion of Cangyuan Realm was not their opportunity, but a signal for Meng Chuan to eat. By the time Meng Chuan broke through the demon world, the human race no longer talked about demons becoming lustful. The demon clan was included in the blood supply list of Cangyuan.
