Chapter 410: Red Bull Iron Forging

```

In that stone cave, there was a blue flame erupting from the ground, akin to a blue pillar of fire, reaching three to four meters in height.

Next to the blue column of flame stood a large bull, its entire body a fiery red.

It resembled the Vajra Bull but was completely red as if aflame. At the moment, the red Diamond Bull was lifting its forelimbs and placing them on a metal platform.

On the metal platform was a piece of metal heated to redness; with each rhythmic lift and press of the bull's forelimbs, it produced the rhythmic hammering sound Lin Shen had heard.

With every strike of the bull's hooves, the shape of the heated metal gradually changed.

As the temperature of the metal decreased, the red Diamond Bull pushed it with its hooves back into the adjacent blue flame, where it hung within the pillar of fire.
