Although the work was effective, Xin Yun was greatly discouraged. He had only dug a hundred meters in a day, meaning it would take a hundred days to dig out a ten thousand meter tunnel—three full months of time. Wouldn't he just drop dead from exhaustion?

Moreover... while cultivating, he was actually resting—cleansing his muscles and meridians with energy and refreshing his mind and brain, which was necessary.
