The Great Nine Heavens Dragon Transformation Formation was a soul-assimilation formation as well as a protective formation.
Not only could this formation turn the dragon vein beneath the Imperial Wind Pavilion into spiritual energy for cultivation, but it also served as a protective shield for the Imperial Wind Pavilion.
As soon as the formation was activated, the entire Imperial Wind Pavilion would be covered within as if it was an invisible steel wok that had been turned over.
Therefore, Wei Wuya, Master Jiesha, and the Ku Rong Old Men, who were in shock after witnessing Ye Chen killing Unquestionable Jian, slammed into the formation shield when they were attempting to run by instinct. The four of them were thrown back one after another.
Horrified, they thought they had encountered something supernatural.
"I-Is this a formation?!" Master Jiesha's lips quivered. His face was filled with disbelief after seemingly recalling something.
