Through checking the General Record of the Martial Demon System, Xiao Shi had a comprehensive understanding of the martial demon realm system. Then, he realized whether it was the runes or demonic patterns he had come into contact with before, they all had the same concept. That was to be able to engrave and seal some special powers.
For example, the Martial Demon Realm expert Xiao Shi had faced back then. Every demonic pattern on his body was a special power. There were strong and weak powers. Some of the powerful strength even exceeded the limits of Martial Demon Realm martial artists. Therefore, he needed to use methods like demonic patterns to seal this power.
"If one were to say that one's physical body, soul power, and other things originated from one's own strength, then the system of the Martial Demon Realm is actually to obtain some powers other than one's own body. Then, they can engrave and seal these powers and use them.
