Counterattack Starts with Signing in a God-Level Sister

Zhou Xiaolong, who was betrayed by his girlfriend and was fired from his job, was at a low point in his life. He accidentally activated the "random sign-in system" and started a counterattack. With the help of the system, he was protected by many "sisters" such as a miracle doctor, the richest man, and the God of War. He relied on the system's skills to beat the villain in the face, accumulate wealth and power, punish the evildoers, and gradually counterattack and reach the peak of his life.
