It was not a spur-of-the-moment moment to subdue Grissom, but Chen Heng had the intention to do so since their first meeting.
When he first met Grissom, he had already understood Grissom's condition. Due to the failure of his participation in the bloodline experiment, Grissom himself suffered a serious injury. Although the bloodline in his body still existed, it was basically crippled.
In other words, it meant that his bloodline had become completely chaotic. Normally, nothing would happen if he stayed put, but if he made a high-intensity movement, it could cause his bloodline to collapse easily. The bloodline power that had finally stabilized became chaotic and violent again, and there would only be one end result for him.
Either his bloodline would collapse on the spot and die, or he would allow the bloodline to mutate and directly degenerate into a bloodline monster.
