Encountering A Heavenly Headhunting Offer
Air Proof was one of the peak-level spiritual contracts and had a terrifying enslaving effect. It was extremely miraculous toward flying beasts.
In the spiritual control world, it was publicly acknowledged that the most dangerous moment for spiritual controllers wasn't when they were fighting in life-and-death combat. Rather, it was when they were setting up spiritual contracts.
Because once this process failed, the spiritual controller would immediately suffer a backlash. They would be injured for light cases and might lose their lives if the backlash was heavy. Hence, if they didn't have 90% confidence, it was very rare for the spiritual controller to proceed with a spiritual contract.
However, after learning spiritual divine languages, there wouldn't be such a problem. Not only would the success rate be high, but even if they failed, the spiritual controller wouldn't be injured.
