Disciple, She Always Wants to Change Her Ways.

[The arrogant and ruthless old devil × longing for a decent young disciple] Demon Lord Yan Ge was ruthless and uninhibited, and he only thought of cultivating a successor when he was about to retire. He randomly picked up an eighteen-year-old female doll with a Tianyin body, and prepared to pass on the mantle. "Cheng Huan, if you feel hungry, you should kill birds to eat." Demon Lord taught. "But Master, are you hungry and want to eat hundreds of birds?" Yan Ge appeared and spoke with his mouth wide open. "Cheng Huan, if you are short of money, you will rob!" Demon Lord said again. "Master, we must work hard and abide by the law to get rich." So Yan Ge worked harder to rob. The demon lord Yan Ge of the generation carefully taught the method of "do not do evil even if it is small". However, his apprentice was determined to do good but was stubborn and unable to do anything. One day, Yan Ge was threatened, and the girl who was surrounded by countless decent people stepped forward. "If you dare to touch him, do you think that my young master of the Demon Cult is dead?!" —————— In Xu Chenghuan's eyes, her master was not a gentleman, but anyone who dared to touch her master would be a heinous person. Demon Lord Yan Ge worked on the training system for a long time, only to realize that he was not training a successor, but the successor's mother.
