Long Chen brought everyone to the Prison Tower.
Since the Princess has already agreed to it, no one opposed it. They all knew that nothing would come of it, even if someone opposed it. Long Chen was already free of fighting, and there was no one who could delay him anymore, so no one opposed it.
They all went with the flow and got themselves imprisoned.
"Stay here. As you said, the Royal Army would send someone to help you. By that time, I would be long gone," Long Chen told the Princess who was on the other side of the cell before he left.
Long Chen and Ji Shan walked out of the Xie Clan together.
Long Chen placed his hand on the shoulder of Ji Shan and said, "The ones who had a hand in killing your love are dead. I know it doesn't change the fact that she's dead, but you can be somewhat satisfied that she would be at peace now."
