All of Emperor Yuan jing's abnormalities were related to something that happened in the 26th year of the Jean.. arc, and were all related to the earth sect's Dao chief ...
My guess was right, the earth sect's Dao chief is the line connecting all the clues. He's definitely related to what happened back then. In this case, it was very clear what to investigate next and where to investigate.
The next target of investigation was the royal hunting ground-the southern courtyard!
King Huai in his youth and Emperor Yuan jing in his youth were attacked by ferocious beasts in the southern courtyard. Most of the guards were killed, and King Huai finally tore the bear apart and resolved the crisis.
There were too many loopholes in this description. There must be experts among the guards of the two princes, and there must be a lot of them. How could Xiong gang kill all the experts of the Imperial court?
Black bear spirit?
