Li Yun stood in the hut, feeling a complex mix of emotions. The diary did contain something about the old man—or rather, something about his family.
The old man had told Li Yun to find his family and give them the diary, as it contained many other things only they should know. Li Yun stopped reading after he reached that point. He read the part meant for him, which included details about his family and where they were likely living at the moment.
He also gained new understanding about this world after reading the diary. According to his grandfather, this place was situated in the lower domain of the Soaring Heaven Continent. This domain contained many regions like the Azure Cloud Region they were in, Snowfall Region, Flowing Wind Region, and so on, with each region containing many empires.
Li Yun was shocked when he discovered the scale of this world, but it was when he learned that the lower domain was the smallest of three domains that he was truly stunned.
