The Blood Soul Curse.
It was a secret art that required the caster to harbor intense resentment, condensing their own Essence Blood into a Curse Blood Mist before death!
Gongsun Yangg's features were faintly visible within the Curse Blood Mist, which shone with a ten-zhang-wide light as it floated above Jiang Chen's head.
The deeper the caster's resentment, the larger the mist and the more intense its light, and it would last for seven days and seven nights!
During these seven days, every time Jiang Chen killed an expert, the Curse Blood Mist would expand, and its light would grow even stronger.
Any expert who saw this ball of Curse Blood Mist would know that Jiang Chen was the one who killed Gongsun Yangg!
