According to the rumors, in order to completely kill a tenth-level unity realm expert, one had to have comprehended a martial intent with destructive properties, such as the violent fire intent or the heavenly lightning intent, and so on.
Most importantly, there was an extremely high requirement with regards to the level of that cultivator's intent.
For example, if one wanted to kill a tenth-level unity realm expert with sword intent, one had to reach the seventh or eighth-level of sword intent.
Although a sixth or seventh-level unity realm expert was not as terrifying as a tenth-level unity realm expert, it was not something that Ye Xuan could deal with currently.
