Yan Junze knew that the task level determination was influenced by the strangeness level within said task.
In other words, if the strangeness level was high, then generally, the task level would also be high. But there were exceptions.
For example, if the strangeness was difficult to deal with, or if the way to complete the task was very special, then the task level would likewise be high and not easy to complete.
Since the task "Reflection Under the Moonlight" has been upgraded to "hair-raising (low)", Fang Ning's strength must have been increased accordingly.
Of course, it's also highly possible that the task mode has changed, becoming no longer that simple; at least like the Back-faced Woman before her Bond Evolution with Ke'er, with Fang Ning fully approached, she could kill Yan Junze in one hit.
However, if this is what a "hair-raising" level task is, it somehow feels like something is missing.
