Fuyulou

"Jade Tower" and the world. "Yulou" is not one person with one surname, but a super powerful alliance formed by four major families - Qinglong Wenren, Baihu Xie, Suzaku Su, and Xuanwu Lu through hundreds of years of marriage and interest bundling. They control the dynasty's economic lifeline, bureaucracy and even part of the military power. They are like a gorgeous and strong cage, imprisoning the entire empire. The emperor is like a puppet, and all the scholars and common people in the world are his fish and meat. The main line of the story is how the protagonist uses the body of a cricket to shake and ultimately destroy this seemingly invincible "Jade Tower".
