The top-grade Vajra Realm expert is indeed extremely powerful, with a body defense that is impervious to swords and spears. Even the Heaven Breaking Divine Weapon of the fourth rank can hardly leave a scar on Li Kun.
However, top-grade Vajra Realm experts are not invincible.
The so-called top-grade level Vajra Realm expert undergoes a comprehensive tempering of the body when advancing from the Entering Dao Realm to the Zhiwei Realm. The body becomes like a crystalline piece of uncarved jade, with very few impurities.
However, having few impurities doesn't mean there are none. Top-grade isn't perfect. Li Kun's seemingly impervious body also has weaknesses.
Experts above the Vajra Realm are extremely cautious about their weaknesses. They wouldn't show them even to their closest ones easily. Once their weakness is discovered by someone, these experts would often painstakingly eliminate that person!
After all, a weakness concerns their life and death!
