Xie Zhang was slightly startled, "He's daydreaming."
The original name of the Northern Iron Cavalry was the Ningzhou Iron Cavalry, and many years ago they still obeyed the orders of the Yuwen Royal Family. Later, the cavalry had four generations of leaders from the Marquis Zhenbei's house, and their loyalty shifted from the Yuwen Royal Family to the Marquis Mansion. Officials often criticized the cavalry as being private soldiers of the Marquis Mansion, which was not untrue. Marquis Zhenbei, Xie Zhang, Xie Jue, and Xie Xun all knew this to be a fact, yet no one dared to speak it aloud.
This was an army loyal to the Marquis Mansion, not the royal family.
