章 646: A Demon Art That Cannot Be Revealed

After transmigrating to this world, she had been undercover in the demon world for two years.

She had originally followed the guidance that Ruan Xin had left behind and her soul had come to this world. Her original body was originally an immortal sect disciple, but because an accident had happened outside, she had benefited.

Mo Ruyue had originally planned to hide in the Immortal Gate and slowly inquire about Ruan Xin's whereabouts. However, she did not expect that her original master would send her to the Devil World without a word and become a spy in the Immortal Gate.

These days in the demon world, she was like walking on thin ice. If she was not careful, she might lose her life.

The immortal sect and the devil realm had always been at odds. They had fought many times, and she did not know what to do. She was stuck in the middle.

They could not kill the people of the immortal sect, nor could they kill the disciples of the demon world.
