I Became a Son-In-Law Through Time Travel, My Wife Is a Master

[Time travel + historical fiction + hard-core business war + strong women and strong men + Machiavellian politics + no system + pure reliance on knowledge] Xu Zheng traveled through time and became a useless son-in-law that everyone laughed at. He was put into a coffin at the beginning, but he was almost buried. The mother-in-law rolled her eyes and even the dog dared to bark at him. He originally wanted to rely on modern business wisdom in this other world to focus on making money and stay away from the hustle and bustle of the world. He secretly made plans and rose to prominence in the business world. The shops he opened were very popular and touched the interests of some forces. Until one day, he saw his wife and slashed the bully who threatened him with a sword... ——It turns out that she is not only a lady, but also a mysterious master in the world! "Madam, your vest fell off?" Jianghu boss: "Uncle Xu, we were wrong, please spare our lives! We are willing to give up all our belongings, just to leave a way to survive!" The powerful man from the aristocratic family said: "Xu Zheng, you devil, you must die a good death! Even if we are ghosts, we will not let you go!" An important minister in the court: "Madman! You are so crazy, you will be punished by God! The Holy Spirit will not spare you!" Xu Zheng: "You asked for this, you can't blame me. Don't forget, the great master's wife is standing behind me!"
