The Undercurrents of Royal Power: Political Schemes

Please Recommend High-Quality Political Intrigue

I'm looking for books like "The Jin Army Besieges the City: Reborn as Emperor Qinzong of Song". The male lead can transmigrate into the past as an official or an emperor, or rise up from the bottom through the imperial exams. I'm open to anything, but I'd like genuine political intrigue and an accurate historical setting. Something like "Sword Snow Stride" or "Celebrating the New Year".
