This book is the orthodox sequel to "Broken Arms Zhaoshuang". The injustice has been redressed in Mobei, and the situation of the late emperor after seventy years seems to have been settled, and the world has entered a prosperous and stable era. Shen Yan's body was damaged by the cold poison. He refused to go to the official position and retired to Qingtan Valley. He originally wanted to guard the mountain for the rest of his life and not care about the turmoil in the court.
But the undercurrent under the peace has not been extinguished, and the border guard veterans who witnessed the secrets of the Mobei Death Battalion died in mysterious accidents one after another. A piece of blood letter came out of the air, revealing the late emperor's second back-up plan that had been hidden for hundreds of years - Jiangnan Water Tower. The dead soldiers in the north suppressed the military power, and the Jiangnan Water Bureau controlled water transportation and wealth. They kept the world in check and balance for generations. When the emperor gave in and overturned the verdict, he was actually abandoning the north and protecting the south, hiding his trump card.
In order to protect the common people and uphold the hard-won justice, Shen Yan re-entered the world, and went south to the south of the Yangtze River with his companions, deep into the rivers and lakes. Step by step, he dismantled the triple deadlock of aristocratic families, assassinations in water towers, and checks and balances in the court.
Su Wan Chaotang alone supported the bottom line of the law, while Xie Shumei took care of the people in secret. Everyone performs their duties and plays games.
This time it has nothing to do with revenge and seizing power, it is just to cut off the emperor's private feud that has continued from generation to generation and lock the root of the troubled times. The prosperous times are never stable for a long time, and there will always be someone in the world who needs to stand up and watch the night. The storm is over, the mountains and rivers are peaceful, but the green mountains remain the same, and people are left to watch over the night year after year.
