The Central Plains.

The old man seemed to be the last obstacle they had to cross before they entered the central plains. Shi Lang did not make any movements until he was told to. He was happy with his comprehension. 

Unlike the people, he did not rely much on opportunities. If Shi Lang had learned anything in the lower realms, it was the fact that humans did not need to rely on the so-called spur of inspiration. In the cultivation field, if a person is motivated, they can create the opportunity needed to excel. 

Many experts have relied on their efforts to reach the peak and ascend. Shi Lang had been comprehending his sword skills. His accumulated understanding of the Dao of the sword throughout his life aided him in analyzing the skills, and the new thinking and scientific knowledge from the lower realm helped him modify the skills into a more efficient version of them.
