Wang Yu took out the raw metal that had just cooled, and placed it on the anvil as he prepared to hammer it. A small number '0/18' appeared beside the anvil, indicating that Wang Yu had to strike it eighteen times to finish this step of the forging.
When Wang Yu raised the hammer, he noticed that there were eighteen green circles on the sword, showing him exactly where he had to strike.
Like the temperature indicator previously, these green circles were a special indicator that came as a result of the refining skill that Wang Yu possesed, normal players wouldn't have this luxury.
Wang Yu tapped one of the green cirlces with the hammer, causing the circle to turn green, showing that this point had already been struck.
Wang Yu raised the hammer, striking at a different circle this time.
