'The material of this box is something else...' Su Chen clicked his tongue. He closed the lid, carried the box back to the training room, and pulled up the instructions for the job requirements—
"In an open area, strip naked and evenly scatter the embers of the hundred-year forge fire in a one-meter radius around your body. Simultaneously, strike your body with a giant metal hammer to resonate with the embers. Once a point of harmony is found, the forge fire embers will actively merge into your body."
Su Chen read carefully. At the end, there was a note in red text—
"After resonance occurs, the temperature of the forge fire embers will rise. The process of them merging into your body will cause pain. Please be fully prepared before attempting."
With the experience of his predecessors to guide him, he could skip a lot of trial and error.
