Wind and snow had disappeared soon after Zhang Tie left the territory of Northeast Military Region. At supersonic speed, only after 6-7 hours' flight, Zhang Tie had already traveled across many climate zones. The southern it was, the high the temperature would be and the more tender the north wind would be. When Zhang Tie arrived at Jinghe Prefecture, Jiangzhou Province, the air was still a bit cold; however, it was warmer than that in Youzhou Province.
The Class A city in Zhang Tie's vision was many times larger than Youzhou Province.
Xuanyuan Hill didn't have a city wall; however, the Class A city in Zhang Tie's eyes had eye-catching red city walls. From the sky, the 70-m higher red city wall was like four arms of a giant or four fortresses which surrounded the entire city.
Given the prosperity of cities in Zhang Tie's memory, besides Xuanyuan Hill, this city could rank among the top ten for sure.
