Clang!
A clear and heavy clunk came from the black iron blank on top of the anvil.
Boss Huang looked at Tang Ling after the first hammer strike and noticed him furrowing his brows. Then, Boss Huang swapped his hand and took a deep breath, a clear and heavy clunk followed after the second hammer strike.
Tang Ling's brows were tightly knitted while he listened to the clunk carefully. The clear and heavy clunk was actually a combination of multiple clunks. It was just that the interval between each noise was too short, hence it sounded like a single clunk.
The clunk echoed in the room. As Tang Ling closed his eyes and carefully listened to the echo, he was able to grasp a general idea of the hammer strike but he still needed some details to make sure.
Boss Huang allowed him to think and was not in a hurry to launch the third strike. When Tang Ling opened his eyes, Boss Huang said, "This is the third strike. Look carefully."
