Chương 5517: Ghastly face (1)

Zhao Hai stood on the main peak of the mountain area of the sacred Institute and looked at the people who were busy working on the cauldron. Five of them were at the river-breaking level, and the rest were mostly blacksmiths.

The five River-breaking level experts were nervously staring at the fire above the big house. They were the ones in charge of controlling the flames above the cauldron. In the entire spirit weapon world, only River-breaking level experts had the ability to control the flames and refine artifacts.

At this moment, Zhao Hai suddenly felt a sense of danger. He couldn't help but look up at the sky. He saw countless dark clouds in the sky, which slowly formed a vortex. The nine Palace meteor formation on the sacred Institute mountain had already reacted. A colorful mist had already covered the entire sacred Institute mountain.
