The Legend of the Immortal Assasin Novel

In 1020 AD, during a violent storm, Lord Terence Frank of the Frank Castle executes a dark ritual in his chamber. He captures a teenage boy and forces him to bleed into a mysterious bluish fluid, which turns emerald green upon contact with the blood. When Terence drinks the potion, he achieves immortality—his scars vanish and his wounds heal instantly, even when he deliberately wounds himself. Intoxicated by his newfound invincibility, Terence refuses to kill the boy, recognizing him as immortal. Instead, he administers a potion that erases the teenager's memories, reducing him to a blank slate. He then orders his ninja warrior Haldar to take the boy and train him in Ninjutsu, transforming him into a ruthless, feared weapon for Lord Terence's service. As Terence revels in his achieved immortality, the boy is led away, stripped of his identity and destined to serve his captor for eternity.
