Betraying the sect had only one outcome: having one's cultivation crippled. This was the most severe punishment. A life could be spared, but their cultivation had to be destroyed. Otherwise, if people could join and leave as they pleased, what would they take the sect for?
Unless one received permission to keep their cultivation, any who betrayed the sect would have it crippled! This was considered the lightest sentence; a more serious offense meant certain death.
Yi Tianyun didn't kill Zhang Bin; he merely crippled his cultivation. This would undoubtedly ensure the lesson was seared into his memory. Celestial Extreme Mansion might be weak, but for him to betray them so casually was unforgivable.
As the Mansion Master of the Celestial Extreme Mansion, he had to be the one to personally cleanse the sect.
"My cultivation! My cultivation…" Zhang Bin cried out in agony. "Steward Xiang, he crippled my cultivation! I'm a cripple now…"
