Qing Lin was the most unpopular seventh prince of the Tianyuan Dynasty. He was born frail and sickly, and even the imperial doctor concluded that he would not live to be twenty years old. However, no one knew that this sick man who coughed up blood all day long had the ambition to annex the eight wastelands and dominate the world burning deep in his heart. One day, a weird "complaint system" suddenly bound him - this system would not give him magical secrets, nor would it help him cure his illness. Its only ability was to complain crazily about everything around him, from the hypocrisy of courtiers to the stupidity of enemies, and also came with some unseemly "venomous suggestions." At first, Qing Lin was so angry that he vomited blood, but gradually, he heard the way to break the situation from the system's ridicule. At the same time, Mo Li, the first genius inventor of the dynasty, was born. He invented all kinds of shocking weapons with the intention of supporting the puppet emperor to control the government. A showdown between a sickly careerist and a crazy inventor begins. Qing Lin will use the system's complaints as a blade, use his sickly body to set up a chess game to seize power, and embark on the road to become a king.
