Liangshan Officialdom: the Struggle for Power

Looking for High-Quality Machiavellian Writing

I would like to read a book similar to "The Jin Army Besieged the City and the Rebirth of Song Qinzong". The male protagonist can travel back in time and become an official or emperor, or he can work from the bottom in the imperial examination. However, I hope everyone will recommend a real plot of power and real historical situations. Celebration of swordsmanship in the snow
