You will need to skim through my lore 6 on celebration in order to understand the context of the 雪红日.
The head attendant beckoned the both of you to come closer, all the while wearing that impish smile on his face. You had both expected to hear something terrible, but what he told you far transcended anything that you can imagine.
“Why, the both of you are the blood banks for our lord. The kungfu they are practicing, which will give them unimaginable power, is too unorthodox. It poisons the blood of our lord. That’s where the both of you and the rest of the sacrifices come into play. Your pure blood is transferred into their body to replace their poisoned ones.”
Your eyes widened. What kind of a person would execute such a cruel act all for the pursuit of power? To treat humans worst than animals, to see them nothing more as disposable objects, indeed, only the person who gave innocent folks false hope just to smash it into bits is capable of such cruelty.
“Now enough chit chat.” The head attendant suddenly snapped. “I may like you now but I have no need for useless people. 雪红日 is coming soon. Earn your survival by helping the sect members to complete their errands. Do not say that I didn’t warn you, if I hear even one complaint against you–”
He tilted his head and the both of you can see death pooling in the silver of his eyes.
“I will make sure you leave here as dead bodies. ”
You’ve successfully convinced the head attendant to let the both of you stay. Now, it is time to prove your worth to him by helping him to prepare with the upcoming 雪红日 (xue-hong-ri; Red Snow Day, also has a double meaning of Blood Red Day). Be careful not to make a single mistake or you risk falling out of grace.
