Trial

"ARGGHH!!!" screamed Angus.

Angus felt being burned alive. The Heart Obsidian in his hand shattered and released a dark black fire towards the surrounding. 

Like a chemical reaction, the liquified molten iron is starting to turn into a colorful color instead of a red molten one, while on top of it, there is a pure black flame that keeps burning.

The scene is bizarre yet also majestic. However, the two dwarfs ignore this and look at the smelting tub in solemn expression.

"I hope you survive, kid." muttered Balrug while looking at the smelting tub.

Inside the tub, Angus feels the hot iron molten destroying his body slowly by melting it. At first, he feels hot and pain all over his body, then the next moment, he feels a weird cold sensation while the pain is still there. After a while, he feels hot and painful again.
