Charles ignited a Blood Flame in his palm, lighting the path ahead.

Saint Michael City had transformed the entire hill into a city, building not only a seven-layered city along the mountain but also carving out seven layers of Labyrinth inside Mount St. Michael.

Charles had already searched three layers and had now found the entrance to the fourth layer of the Labyrinth. The fourth layer was concealed by a black stone door, upon which was written in ancient script: "None but the descendants of Michael shall enter this gate!"

Of course, Charles was not a descendant of Michael, but he was not about to heed the warning.

With a slight exertion of his gathered energy, black flames burst from the door, forming seven fire snakes that coiled towards him.
