The Dayin Dynasty suppressed the dragon veins and was established to cultivate the country through martial arts. Immortal cultivators need to absorb Qi into their bodies, refine their Taoist hearts, and walk on the path to immortality before they can reach the gate of heaven and become immortals. The dynasty established a nine-level official system, with monks serving as officials, mortals farming and fighting, and the strong able to break the soil and become marquises. However, cultivation resources are monopolized by the royal family and aristocratic families, and it is difficult for a poor family to produce a noble son. The protagonist, Xiao Jingxing, was originally a down-and-out nobleman. He was burdened with an injustice against his family and was living as a clerk on the border. He just wanted to eat and wait for death every day. One day, I awakened the "Salted Fish Counterattack System". As long as the worse it is, the faster my cultivation level will increase, the more stable my Taoist heart will be, and I can also pretend to be useless to pick up heavenly materials and earthly treasures, and conquer the ancient immortal soldiers. On the surface, he is lazy and inactive, but in fact, he has the highest level of force. He can defeat all obstacles with one punch, pretending to be a pig and eating a tiger to slap the powerful in the face. His childhood sweetheart, the female swordsman Xiu Ning Hongxiao, accompanied him all the way, but she didn't know that he had already changed his fate against fate. As the system mission progresses, he becomes involved in the struggle for imperial power and reveals the secret of the immortal sect suppressed by the dynasty - the so-called immortal path is just a scam used by ancient emperors to refine the Taoist hearts of all living beings. Xiao Jingxing went from being a salted fish to holding a sword to fight against Tianmen, breaking the shackles step by step and re-establishing the world.
