Su Yu was indeed playing around. He was playing an expensive game for free.2

His fire of civilization was burning.0

On the 20th floor, he was starting to have difficulty fully absorbing the teachings of the old man. He had been resetting the level to observe the process multiple times.0

For a weaponsmithing trial, it was very easy to reset the level. He only needed to forge a weapon with ten golden stripes to get through the floor. If he wanted to reset it, he only needed to add one golden stripe on top. He could do this all the way to eighteen stripes. With eighteen stripes, a weapon would reach the peak of middle-tier yellow-grade.3

Su Yu was constantly forging at the side while observing the old man. He would not stop unless the old man stopped. He was basically mirroring the old man's movements. When the old man slammed his hammer down, he did the same. When the old man adjusted the fire, he did the same as well. At the moment, he was not using any of his characters for the forging. That was something for the future when he further improved.0

Again and again, he forged. This place was a massive money saver. He could practice weaponsmithing without using real materials. Then again, he could probably gain even more if he was using real material...2
