(with some sword flurry of fanfic) Taoist companion was killed, and he fought back and fled to another world powerlessly. With hatred in his heart, he farmed and raised children in this weird world. He only hoped that one day he could practice Mahayana and then go back to avenge his husband. But she didn't expect that with the in-depth understanding of this world, she noticed the ambitions of current affairs, and after breaking their conspiracy, she got a treasure. After accumulating the law of cause and effect, she could turn things around, and maybe she could save her husband. (Some The male protagonist is one-on-one, transparent people, probably appearing at the beginning and the end, and there is no male protagonist in the middle)
