This short blade was obtained by He Kao from an assassin's hand last year when he saved Yang Lingxi's mother, Chen Yuhua, in Nanhua.
At the time, it felt particularly sharp, so He Kao kept it. After his cultivation broke through to Tier Three, he discovered it was indeed a precious blade, with a very special material and imbued with mana.
Its surface looks like metal, treated with a matte finish resembling bluing, yet it neither conducts magnetism nor electricity, and shows no reaction before a metal detector; however, when divine sense is injected, it flows very smoothly.
He Kao used this blade to dig out three large frozen soil chunks in the icy land, within which lay three pieces of old ginseng.
The assassin was a secretly trained cleaner by the Huiming Shi Family. The Huiming Shi Family has a so-called Cleaning Department, specializing in dirty work in secret, established by Gu Jiang, the adopted son of Patriarch Shi Zhizhai.
