Common Hammer?

The young man was none other than one of Edmond's adopted children, Dark flame.

Compared to other young cultivators, Dark flame had a very high affinity with the fire element which made him learn some good fire techniques which help him in forging or alchemy.

To him, alchemy was a mystery. 

Also, he had a huge impact on forging after seeing someone forge a weapon in front of his eyes.

However, he didn't use the first two things to learn the forging; instead, whenever he got time, he would just perform the set of movements that the forging master did from his childhood and wanted to get enlightened.

Later with the help of Edmond, he studied some books relating to that and had gained some knowledge but he was still not close to becoming a rank 1 forging master.
