Ninth-grade physical body

This was actually a body-tempering cultivation technique.

It seemed that Zheng was cultivating this flaming Vajra Arts.

Body-tempering cultivation techniques were extremely rare in the divine wilderness continent. Furthermore, body-tempering cultivation techniques were known for being difficult and slow to cultivate.

By cultivating a body-tempering technique, one's body would constantly become stronger and possess all sorts of unbelievable abilities.

According to the strength of the body, the body was divided into nine grades.

Rank-1 was the weakest and rank-9 was the strongest. There were three levels: lower tier, upper tier, and peak tier.

However, the path of body refinement wasn't a single path. It was a type of martial Dao, a supplementary type. Just like the path of inscription, it supplemented the martial Dao.

This was because if one's physical body wasn't combined with martial arts, one wouldn't be able to unleash the power it should have.
