Part-Time Protector, the Young Master Seems to Be a Little Dead Again

When I asked you, I have been working here for two hundred years, when will I be promoted? You tell me, as long as I act as a protector for a few young masters and keep them alive for three years, they will be promoted. I originally thought I could pass 90% this time, but I didn't expect it was only 86%, because the young masters seemed a little dead!
