Heart-attaching Thread
๐ค Owner: Old Woman (Long Li Niang)Origin
A rare type of demon insect. After hatching, it's as thick as a chopstick. When captured and refined by insect-controlling experts, it gradually thins until invisible to the naked eye, achieving great success.
Effects & Usage
Used to attack enemies, colorless and formless, hard to guard against. Once it enters a host’s body, it will pierce the heart at midnight, causing instant death. Difficult to trace the cause of death afterwards. The one used on Hai Dayue was not fully refined but still represented centuries of effort.
