As the royal family of the Northern Three Thousand Territories, the Tian family had a vast territory under its jurisdiction. Each key city was also vast and boundless. Ye Qianli and the others landed in the Tian family's largest city after the Tian family's imperial city, Tianlin City.
Tianyin City was located in the northeast corner of the Tian Clan's jurisdiction, adjacent to the Three Thousand Western Territories. It was the fortress between the Three Thousand Western Territories and the Three Thousand Northern Territories. Not only was it rich in resources and prosperous in commerce, but it was also a strategic location for the Tian Clan.
Therefore, there was an elite army of the Tian Clan stationed in Tian Yin City all year round, known as the Heavenly Army! Directly under the control of the Tian Royal Family, only the Tianyin Marquis, Tian Zhaoyu, had the authority to command the Heavenly Army.
