The toxin in the wisteria flowers was something she had gathered along the way when she first came up the mountain. As for why she could extract a poison from wisteria that specifically targeted demons, it was far too easy for Keqing.
She knew demons feared wisteria flowers. In the future, Shinobu Kocho, the Insect Hashira, would primarily use wisteria poison to kill demons.
Born physically weak, Shinobu had found another path in battle. She used toxicology to extract wisteria poison, thereby achieving her goal of exterminating demons!
Knowing about it was one thing, but Keqing still had to witness it for herself.
"Lady Keqing, that makes twenty-seven."
Standing beside Keqing and holding an umbrella, Makomo could not help speaking up.
On the way up the mountain, Keqing had already killed twenty-seven demons, and every single method had been completely different! Makomo had once believed that killing demons required either a Nichirin Blade or waiting for daylight.
But after following behind Keqing, she finally understood that there were simply too many ways to kill demons. Some she understood, while others she had never seen before.
Take the wisteria poison now. She knew demons feared wisteria, but actually using wisteria to kill demons was rare. First, wisteria had a short blooming season. Second, extracting the substance within it that targeted demons was no simple task.

Wouldn't that mean this trial was...
