"Now is the chance to test the level of trust," thought the Celestial.
When Siegfried threw him away, Fang kept healing spells ready. He didn't need to lose a companion or become a murderer on the second day. However, everything ended quickly with the arrival of an official representative. After hearing the versions of what happened from the Nix, Matthias, and Nokou, Fang took out a passport of the Celestial Empire from the inner pocket of his robe (if they are indeed like Chinese, why wouldn't they exist in this setting? :3) and approached the arriving mage.
"My name is Fang Pei, and I am a student of the Yao Lin Monastery of the Celestial Empire. And I have never killed anyone in my life. My calling is to save people, not to destroy them. It is quite possible that the murderer of this gentleman's brother was a monk from another Order; I know for sure that there are monasteries where warriors are trained to kill. But Yao Lin is an order of healers, and this can be easily confirmed by all the documents."
