This seems to be a dual cultivation method of law body and Dao, created by the Emperor of the Ancient Black Dragon Imperial Court according to his own conditions. The most suitable person to practice it was the Emperor himself, followed by his descendants with the same bloodline.
Other people cultivating it would find themselves exerting twice the effort for half the results, futilely expending their energy.
However, for Su Yu, who possessed a Proficiency Panel, such conditions were irrelevant. If he decided to practice, he was bound to fully master the Black Dragon Battle Method.
'If I were to cultivate the Black Dragon Battle Method, and then go deal with the Thunder Dragon Immortal Dynasty…' Su Yu could easily imagine the expressions of the people from the Thunder Dragon Immortal Dynasty at that time.
He shifted his gaze away from the immense black and red shadow of the giant saber, turning towards the last shadow that seemed to be a ten-layered Dao Tower.
