Ying Chang'an, the most inconspicuous second son of the First Emperor, had been dormant in the palace for several years, and no one cared about him.
Awakening the Gu system at the age of twelve, he started out as a poor blood-sucking Gu, squatting in back alleys, working in gambling houses, and snowballing by bloodletting ruffians.
After eight years, the blood volume exceeded 1,000, and the second level of the Gu spectrum was unlocked - the Yuan-devouring Gu absorbs internal energy, and the Heart-devouring Gu takes human lives.
A soft-headed young man turned into a murderer in an instant, what's left of the Qi Kingdom? Ghost in Shu County? Taking a person's head from a thousand miles away is just a matter of a Gu insect moving.
