The world is in turmoil, and the princes dare to do it. Gao Jixing, the military governor of Jingnan in the Five Dynasties and Ten Kingdoms, risked his own life and went north to Luoyang in order to ensure the peace of the region. Outside the city gate there is murderous intent, and above the banquet there are the lights of swords. What he has to face is not only the temptation, scrutiny and use of Emperor Li Cunxu of the Later Tang Dynasty; he also has to guard against the secret calculations from the Later Tang Dynasty and the people around him. "Life hangs by a thread" not only describes Gao Jixing's journey, but also describes the fate of every powerful official in the Five Dynasties and Ten Kingdoms. He can only rely on loyal ministers, wise men, and dead men to escort him to face all kinds of doubts. This is Gao Jixing's retrograde path and the most thrilling gamble in his life. In troubled times, there is no question of loyalty or treachery, only who can make it to the end. Right and wrong, righteousness and benefit, going alone and following the crowd... What we see is the confrontation between the north and the south, the struggle between the government and the opposition more than 900 years ago.
