Nice. Few things to add,
Jian Feng is from the Xiuzhen Continent, right above Yanwu - there are three realms in total. Di Ming Jue is from the realm above that - Xiuxian continent
The people that came to rape Muyan is the Emperor of the highest-order country in their continent, not someone from the higher realm. He wants to marry Muyan so she'll support his country instead of Lou Beiyu's (stupid apprentice).
There are a LOT of people looking for Muyan. Currently, she's mostly conquered Yanwu continent and planning to make her subordinates ascend with her and Xiao Bao... so let's count the people that want to kill her.
1) Xiuzhen Continent - Every powerful sect saw the "vision" that Muyan caused because she was building her spiritual root - a very basic xianxia thingy that determines talent. This vision was visible in all three realms, a "moon root" (haven't decided on what to call it yet). The common ones, as seen in other stories, are the earth, water, fire, lightning, mix of them, mutated etc.
They know it's powerful but they don't know where it is, not even which continent. Jian Feng wants help so he gave Muyan's information to his sect. They want to cook Muyan and Xiao Bao into elixirs/Dan.
2) Xiuxian Continent - it is SO hinted that one of the factions that want to kill the Shen Musician heir is the region ruled by Di Ming Jue. (potential dramaaaa~ I'm a masochist and self-manipulative).
But the ones that want her to die the most in Xiuxian Continent is the faction that controls alchemy and medicine. They basically demonize the Shen Musicians because the latter makes them obsolete. That, and they want to steal the inheritance. These are the people that descended to the Xiuzhen Continent to begin searching for the Shen Musician, and they're beginning to suspect that the heir caused the "vision" as well-
Jian Feng's sect is somehow affiliated with them, it feels like it has the same structure of a mother company visiting a branch.
That's how they met GQX, gave furnace-GQX the drug, then made GQX go back to Yanwu and inflict it on Muyan because it will prove her claim the the one who created the "vision" is in that continent. That drug is attracted to the one with the purest energy it could find, and the evil people have a lot of clues to go on.
It's okay though, the MC-halo keeps the MCs safe
Btw, nobody wants to go to the Yanwu continent because it will corrode their spiritual energy. Even Jian Feng's sect is only there because eating Xiao Bao is too attractive.
Tbh, I want GQX to survive. She seems to have exhausted the damage she could possibly cause, she already gave everything that she knew to the most dangerous people... and I just want her to see the MC's glory muahahahaha
