That's a helluva good entrance. Some good original concepts in this. It's hard to nail down the MC. He seems set on revenge for his gp. But also has serial killer vibes. I... guess he's not pure evil considering who he's killed so far. Maybe the og third son. But even then there was malicious intent.
I guess I'm kind of glad this isn't just another cultivator story full of fighting and pills and meditating. The pill concept really, to me, doesn't make sense. Like is that a legit thing or just a trope to advance the story and make op characters? The meditation part can make sense, but so many stories make it out to be meditation=power. Perhaps mental, but physical? I'm rambling I suppose. Be well out there.
