Chapter 170: The Princes' Past II

With his decision made, Prince Yi left the capital and made his way to their secret army base to prepare the troops and wait for the Crown prince's order. Since his father never cared for his presence, he was always able to travel as he liked, going and coming as he pleased with no one questioning his movements. And so he used his invincibility to amass and see the progress of their troops. So the men knew his face, but knew of the Crown prince in name only. 

He quickly arrived on the base and began to make the arrangements while coordinating plans with the Crown prince in the capital. They had agreed to execute the plan slowly over a long period of time so as not to alert their father. So Prince Yi had been steadily sending men bit by bit to Crown prince in the capital.
