The entire royal bloodline of Yang Country was personally exterminated by Yang Jiande, who practiced the ruthless and desire-eliminating Blood Demon Codex.
In the past, there were some concealments. The death of the Yang royal family was often proclaimed to be due to illness.
After publicly slaughtering the Crown Prince Yang Xuanji in the grand hall, Yang Jiande hardly bothered to find excuses anymore, directly summoning his kin to the palace and annihilating them all in one fell swoop.
The ruthlessness and desire-elimination of the Blood Demon Codex was his secret weapon; therefore, secrecy was of utmost importance.
To achieve this goal,
The court officials, palace maidens, and eunuchs who witnessed the event at that time, except for a very few completely trustworthy confidants, were all eradicated by Yang Jiande.
Therefore, the matter was temporarily hidden within the royal palace and not leaked to the outside.
