The supplies that Yan Liqiang purchased the day before included things like mattresses, cutlery, three chicken feather brushes, twenty odd large sewing needles, a box of gum, a roll of paper, and a pair of scissors.
Nobody would ever think that these things could be made into weapons capable of taking human lives. But when Yan Liqiang returned to his small courtyard, he carried the pile of supplies he bought yesterday into a room on the first floor and began crafting his murder weapons with the items.
