Xiao Chen, the god of war in the country, was seriously injured and died, but his soul traveled to a parallel world and possessed a vegetative son-in-law. Facing his family on the verge of bankruptcy, his seriously ill mother, his sister who was forced into marriage, and his contract wife who treated him coldly, he decided to shoulder everything for "himself". He uses military skills to operate the stock market, uses martial arts to intimidate Xiao Xiao, and silently protects this crumbling home. Until powerful enemies from other worlds came to hunt across borders, the power of destruction enveloped the city, and the world fell into panic. Xiao Chen stood up in the air under the gaze of everyone, and said calmly to his family: "Don't be afraid, I once was one person against a country." From then on, the adopted son-in-law who was hiding in the market became the only guardian angel in the world.
