Gloomy autumn rain had been falling for two or three days straight.
In an alleyway in the outer city.
"Constable Li, we've investigated thoroughly. Huang Gun stayed in that courtyard for two days… then someone went in. It looks like it was searched, but there are no signs of a fight…"
Li Yuancheng squatted in the alley, an Express Squad constable reporting the situation from the courtyard behind him. He paid no mind to the words of his disciple, Tong Xiaowu, who stood nearby. Instead, Li Yuancheng was absorbed in caressing the packed-earth bricks at his feet. Several of them were cracked…
CRACK!
Li Yuancheng's fingers tensed like an eagle's talons, prying up several of the packed-earth bricks. Beneath them, yellowish-black traces were visible, already melded with the soil.
"What is this?" his disciple, Tong Xiaowu, asked.
"Corpse-dissolving powder."
