Wei Cheng remained silent for a long time.
This was indeed a significant problem he had encountered, due to the rapid development of this area, he was finally able to catch up to the plot and see the truth hidden deep within.
The normal plot would be that Chi Yao escapes and annihilates the Floating Cloud Sect, Cangwu City.
After aiding the escape of the Wind Demon, he also destroys Tian'nan County, and the Tianji Sect.
Each event was supposed to follow the other.
But now, the chain of events has broken.
Chi Yao can't help the Wind Demon escape.
Therefore, the Wind Demon can't destroy the Tianji sect.
Wei Cheng and his companions don't have the strength to fight against the Tianji sect yet.
They represent the orthodox cultivation.
If Wei Cheng manages to destroy the Tianji sect by chance, he may be accused of being an Alien Demon.
In summary, this is a deadlock.
Destroying the Wind Demon would offend the Tianji Sect, who would then call on their allies and defeat them.
