14.98 Last Violet Star - (Past) Dilemma

At the mountain peak in the Lan Zhuayan Sect which is known as Yun Xiajie's Peak...

Yun Huaxia leaves the Main Peak's Medicinal Hall and makes his way to his younger brother's courtyard. He appears to be quite upset and resentful that his father is guarding Bai Wuan rather than worrying about Yun Xiajie, his youngest son, who had drifted sleeping for unknown reasons.

There is no evidence that Bai Wuan did anything to his younger brother to cause his current condition, but it doesn't imply he had nothing to do with it. After all, he was with his younger brother for the last moment before he lost consciousness. These circumstances forced Yun Huaxia to regard Bai Wuan as a suspect.
