After the Slaughter God Hall was flattened, Fire Cloud Immortal Venerable and the Sect Leader of Heavenly Gate Dao Sect, Wan Lunhai, indeed felt some fear towards Jing Yan.
Whether it was the Fiery Flame Extreme Territory or Heavenly Gate Dao Sect, their defenses could not completely compare to the Slaughter God Hall.
One simple example is that neither of these places could produce a formation comparable to the Twelve Devine Demon Array. The Twelve Devine Demon Array was personally created by the Immortal Emperor who established the Slaughter God Hall, and neither the Fiery Flame Extreme Territory nor Heavenly Gate Dao Sect had an Immortal Emperor to create a Big Array for them.
Even so, the Slaughter God Hall was still destroyed.
