When Lin Shen swung the hammer dozens of times, Dao was already a bit surprised, "This kid's endurance and skill durability are truly extraordinary."
"It seems the material isn't hot enough anymore, can't hammer it." Lin Shen stopped, and Dao thought he couldn't hold up anymore, but Lin Shen said this.
Dao had been so focused on watching Lin Shen swing the hammer that he hadn't noticed the metal had cooled down significantly, no longer red enough, and had become too cool to effectively forge.
The piece of material that Lin Shen hammered was uneven, probably needing to be re-melted and re-forged.
"Not bad, really not bad, but you're swinging the hammer all wrong. You should swing it like this." Dao took the hammer, placed another heated piece of metal for demonstration, and showed Lin Shen how to swing, how to exert force, and how to control the strength and accuracy.
Lin Shen tried several times but always missed the crucial point.
