Guarding Tianlao for 12 Years, I Became the Best in the World

In the ninth year of Guanghua, Ling Yun traveled to the Jiuli Empire and became a small jailer in the empire's huge prison. This empire, which lasted for six hundred and thirty-seven years, was already in critical condition before Ling Yun arrived. The clan members and bureaucrats of the empire were arrogant and reckless, creating countless unjust, false and wrongful cases in this prison. As a jailer, Ling Yun could only choose to protect himself wisely, and was always worried about his own future. But after awakening to the Star of Tomorrow System, his life changed dramatically. It was exactly 12 years later that people suddenly realized that the guy who walked out of the prison was actually the most powerful official in the history of this world!
