This Country Is a Bit Chaotic

With a misplaced identity and a different life, he came to this magical world by an accident and became a pawn on the Qi Kingdom's frontier, Yunjing. Yunjing had no desires at all, but things were unpredictable. A mysterious team brought him to the center of the world - Qidu. This majestic city that ranks first in the world is currently in endless turmoil. At the top, the emperor is old and the disciples are young, but at the bottom, the foreign vassals are self-respecting and have been suffering from border problems for a long time. Countless hatreds between the country and the family, and chaos in the court followed one after another, weaving this place into a huge whirlpool. The waves are overwhelming, the building is about to collapse, and the ants are trying to survive, but I am the only one holding up the sky!
