For each disciple who successfully recruited a suitable one, he could activate a star marker in the [Innate Dao Diagram] and obtain top-tier immortal cultivation techniques and martial arts skills! When Grandmaster Yu Xiaogang used his "Ten Theories of Martial Souls" to mock my disciple as trash, my disciple unexpectedly punched away an opponent whose soul power was more than ten levels higher than his, slapping him in the face in front of everyone!
