"Alas, the image of standing upside down, swinging fists, and stomping to carve out tunnels is pretty ludicrous if you think about it even for a bit. So, relying entirely on fists to create a passage really isn't a wise decision, which means I probably should look for some other method of tunneling."
As soon as he thought about other methods of tunneling, Zhang Yanhang immediately thought of the versatile Alchemy, which was indeed quite professional for solving the situation here.
"Previously, I estimated that using Alchemy to penetrate the hundreds of meters thick walls in the Crimson Iron Ant Nest would take at least several minutes or even more than ten minutes, but now it seems I might have underestimated Alchemy, or perhaps my method of application wasn't quite right."
