The Guandong Troop of the Jiang Family did not include anyone who ran away just because they were devoted to the Jiang Family.
He was little when his grandfather passed away, and grandmother once stressed that the Guandong Troop was not devoted to the Jiang Family, but to the court. It was the most straightforward and mature army.
If the Jiang Family was so ambitious, grandfather would not have just married grandmother, and had one daughter.
That was the most shallow logical principle, but his father never thought about this point at all.
At that time, Zhou Huaijin just wished that the investigation had been conducted upon whether it was really some deserters from the Guandong Troop who ran away, but his father said that the Guandong Troop was related to the Jiang Family, and that the whole thing should have been dropped because the Queen was part of the Jiang Family.
