In the realm of martial arts, the fourth transformation of the Core Body Realm marks the threshold of becoming a half-step Sword Immortal.

Surpassing the limits of the Houtian stage and stepping into the Xiantian domain leads to the Dharma Aspect Realm.

The Dharma Aspect Realm is divided into three levels: Earth Dharma Aspect, Heaven Dharma Aspect, and Martial Soul.

These three levels correspond to the minor Sword Immortal, major Sword Immortal, and celestial Sword Immortal among swordsmanship practitioners.
