Divine Craftsman Lou Gao's Calling Card

Below the bead had originally been an enormous metal vein.

Only after Gengxin City's ancestors discovered a branch of this vein had they built a city here.

After centuries of mining, this vein had long since been discovered by successive city lords of Gengxin City. However, because it lay deep within the Iron Ridge Mountain range and was buried relatively far underground, it had never been mined. After all, the outer branch veins alone were enough for Gengxin City to keep mining for several more centuries. Without modern industrial machinery, even excavating a small metal vein would take decades, even a century—and that was to say nothing of Gengxin City, which relied entirely on manpower.

And now, this giant vein had already been completely absorbed by Xiao Yun's Martial Soul Bead, leaving behind an enormous underground cavern that wound for dozens of li through the middle of the mountain range.

Aside from a small amount of ore still hidden within the soil, stone, and mountain rock, this vein had lost all value.

The Martial Soul Bead slowly flew up and drifted toward Xiao Yun.

Xiao Yun reached out and caught it. The bead felt warm in his hand, its surface smooth, and he could sense the immense energy contained within.

The three elements of earth, water, and metal had reached a balance inside the bead, relying on and promoting one another to form an unstable triangular structure. For the energy within to complete its circulation, it was still missing two elements—wood and fire.

Only when the Five Elements were complete could the Martial Soul Bead finish its transformation, becoming a World Bead with an independent small world inside it, completing Xiao Yun's Martial Soul Evolution. Then Xiao Yun would truly possess Soul Power as well, greatly reducing the suppression Douluo
