After Stabbing the Demon Lord in the Back

Demon Lord Shi Yuan was cruel and ruthless, but his cultivation had reached the state of transformation. He had been suppressing the righteous path for thousands of years and could not lift his head. It was said that he was cold-hearted and merciless by nature, and was ruthless to others. He only loved one concubine, Shen Ji, the most. Later, there was a battle between good and evil, and the demon king firmly gained the upper hand. Unexpectedly, his beloved concubine Shen Ji pierced his heart from behind with the evil-killing sword, and the demon king died. Shen Ji was originally an undercover agent sent by Zhengdao to the Demon Lord. After assassinating the Demon Lord, she became famous with one sword. Unfortunately, she was infiltrated by the devil's energy and lost the memory of her relationship with the Demon Lord. From then on, she was protected by the master, kept in seclusion, and did not care about worldly affairs. A hundred years later, Shen Ji picked up a pitiful young man on the roadside. She felt pity for him and took him as her disciple. The young man behaved well and served him tea and water every day. Later, Shen Ji's memory recovered, and she was horrified to find that the boy she picked up was the demon king who was assassinated by her! The Demon Lord stood in front of her bed with a smile: "Master, do you need to warm the bed?" Purpose: Even in adversity, never give in to power and bravely pursue love and freedom
