The figure that suddenly appeared was the Heavenly King!
Ji Xiaoxiao's control of the dream world's rules could not affect him. After all, he was a six-star, and his level was equivalent to a complete world.
If he hadn't discovered a special rule and wanted to study it, how could he have given Ji Xiaoxiao the time to chant a forbidden spell?
That law was so special that even the Heavenly King had a feeling that once he could successfully comprehend it, he would be able to perfect his 'world'. It would be one with two sides, and the Yin and Yang would be perfect!
Coupled with the large number of 5-star horde leaders that he had forcefully absorbed through treasures over the years, it was not impossible for him to spy on the legendary 7-star realm!
That's right, the special law he discovered was the Mental Demon Law!
The Mental Demon Rule was not an innate rule. It was born after birth due to the uniqueness of human martial arts.
