He was once an undefeated god of war who dominated the battlefield with his martial arts. Once he achieved great success, he was framed and stripped of his military power, and became the most despicable son-in-law of the Marquis of Jing'an Mansion. Everyone in the Hou family was ashamed of him, and cynicism and sarcasm followed him everywhere. Carrying water, chopping firewood, serving tea and pouring urine became his daily duties. The hands that once conquered thousands of armies with the help of national martial arts can now only touch menial jobs. The ultimate national martial arts skills are tightly hidden in his bones and blood, and he does not dare to reveal them at all. The high walls of the deep house are like a cage, trapping not only the body, but also the burning heart that once wanted to protect the country. Others only thought that he was cowardly and incompetent and allowed others to bully him, but they didn't know that the downcast eyebrows showed the foundation of national martial arts that could not be erased and the blood feud that could not be suppressed. Every forbearance is the accumulation of inner strength, every humiliation is the accumulation of strength from the sheathing of the blade. When suppressed to the extreme, this son-in-law in the dirt will eventually break the situation with national martial arts, but the road to breaking the situation is full of blood and sadness.
