Scared witless!
This was Leon's inner assessment of Yun Hao at the moment.
As he had said, Yun Hao was someone he personally trained, and it's even fair to say that before Yun Hao became an instructor, all the missions Yun Hao carried out were personally arranged by him.
So when he received the news that Yun Hao betrayed the organization, he personally led the chase to kill Yun Hao.
It wasn't because he cherished Yun Hao, but because Yun Hao knew many of his secrets, including the treasure he secretly stashed away from the organization and Soul Refining, which Yun Hao helped him to hide.
Therefore, he must kill Yun Hao with his own hands to ensure the message doesn't get leaked.
Fortunately, although he didn't kill Yun Hao in the end, Yun Hao didn't speak about it to anyone else either.
However, the treasure he hid was completely taken away by Yun Hao.
