"Grand Elder, why is the flying sword soaring into this thundering calamity?"
Elder Wu regained his sight. Even with his knowledge, he was unable to tell what caused the flying sword to react this way, hence the question at the Grand Elder.
"Some high-tier artifacts defy the law of nature, hence they will go through the so-called thundering calamity. It is a phenomenon where one's cultivation reaches a certain height and must go through the calamitous path of thunder to ascend beyond."
The Grand Elder actually kept the truth from Elder Wu in order to protect Zhang Zhi. A high-tier artifact would never attract the heavenly thunder, the phenomenon happened because Zhang Zhi's sword was an epic-tier artifact and it made the heavens jealous, hence the thunderous punishment.
The group of cultivators were in deep thought. It seemed like Zhang Zhi's sword was the best of the high-tier artifacts.
