Chapter 410: Red Bull Iron Forging

Inside the stone grotto, a blue flame shot up from underground, resembling a blue fire column that rose three to four meters high.

Beside the blue fire column stood a massive bull, its entire body was fiery red.

It resembled the Vajra Bull, but its body was red like flames. At that moment, the red Vajra Bull raised its front hooves, placing them on a metal platform.

The metal platform held a piece of heated, glowing red metal, and as the red Vajra Bull rhythmically stomped its hooves up and down on the metal block, the sound Lin Shen heard reverberated clearly—like rhythmic hammering.

The shape of the glowing metal was gradually changing under the impact of the bull's hooves.

When the temperature of the metal cooled, the red Vajra Bull nudged it forward with its hooves, sending the metal block sliding into the nearby blue flame column, where it hovered suspended within the fire.
