So actually, re-reading the first section of the novel... what's up with this fandom and outright contradicting the story's most basic exposition?
Things that are set up during the Mo arc in the novel that the fandom feigns don't exist:
Wei Wuxian meditates twice before things go to shit, partly to acquaintance himself with this new body he's inhabiting. During this time, it's explicitly mentioned he's building up Qi, aka Orthodox Cultivation.
The entire exposition on how Guidao works goes ignored. Starting with the fact that Wei Wuxian only requires his voice to do Guidao with "no fancy rituals or seals involved", he's such a powerful ghost cultivator however that his voice carries so much power it will freak out most weak ghosts into terrified immobility at his power. This makes them useless.
While he can tone down his voice and be as gentle as possible, it's still too much for a weak ghost that's unused to him. There are two ways around that problem: he either "breaks in" the ghost (like one would a horse they want to teach to be ridden) which takes time and works better on ghosts he woke himself, or he uses a tool (like... a flute *wink*) to further soften his commands to something bearable to them. The flute probably also has the advantage of furthering his range, but its main purpose is pointed to be a dampener of sorts that allows him to get weaker unfamiliar ghosts to collaborate without freaking out at the onslaught of power.
All these problems become a non-issue for stronger ghosts, which is likely why he says in the narration that the fiercer the fierce corpse, the less trouble they give him.
This isnt the first chapter, but his ghost cultivation talismans are not mentioned to be powered by his own (resentment) energy, but by smaller spirits too weak to be otherwise useful that he keeps catching around. In the Dafan Mountain arc, he's outright frustrated at his lack of success finding useful spirits despite creating a bag to hold them and carry them around.
He can further boost a ghost under his power using sound. In general, the initial chapter ties WWX's power to breath (a classic symbol of life) and sound, not having resentment in his body. While building up normal Qi is brought up multiple times, resentment goes virtually unmentioned regarding WWX himself.
Nowhere it's implied that sharing Qi with a non-cultivator is ineffective. Lan Sizhui heals with Qi two perfectly average people during this scene, and the most the narration points out is that trying to do two people at the same time is clearly too much of a reach and he's struggling to get the job done.
Hm, I think you may have gotten the purpose of the flute vs. voice mixed up. Wei Wuxian’s flute doesn’t “soften” his commands so that low-level dead can obey him; it makes the dead he can already control easier to control. Perfect example is how Nie Mingjue’s corpse could struggle out of and ignore his voice prompts in Guanyin Temple, but the moment Wei Wuxian uses Chenqing, he’s easily able to lure Nie Mingjue into the coffin. Low-level dead, on the other hand, are afraid of Wei Wuxian because they do not have the resentment to blindly follow him like fierce-levels do. That’s why the farmers’ corpses in Mo manor cower away from him, but he could just waltz up to the Mo family corpses, tell them to get to work, and they start fighting with a passion. Wei Wuxian cannot boost the dead’a resentment on his own at all, which is why he used the blood pool in the Burial Mounds. Without that, he can only work with the level of resentment the dead already has, which is why low-level dead are useless to him.
That's what I meant by soften the commands, so it seems less "got it wrong" and more "expressed it in a way that may cause confusion to someone who hasn't read the book" so I appreciate the clarification!
Soften as in "make easier to actually get Undead he already controls but would cower at him to not panic and obey". Wwx himself tries to talk more gently during the scene when he's still trying to make the random fierce corpse work, so that's the imagery that came to mind.
In general, it all seems a wording issue so I'll just thank you and move on.
