The God of War Chokes to Death on Tea, Then Transmigrates to the Countryside as a Son-in-Law

【For male readers? Female readers?】I don't even know what kind of book this is anymore. I'm starting to worry about the author's mental state... As the God of War of the Earth under the Great Emperor of Gouchen, he chokes to death while drinking tea at home. His soul transmigrates into the body of an unconscious middle-aged villager, turning him into a rural live-in son-in-law. That very night, after rescuing a young married woman from the village, she invites him to sleep with her. Perhaps it is the cycle of karma, or perhaps it is fate. One day, the God of War discovers by chance that she is the reincarnation of his poor, beloved wife! Since destiny has brought them together again, he will protect her this time! He won't let history repeat itself! First, he avenges the wrongs done to his wife in this life. He'll make the family that has always bullied her pay ten or even a hundred times over! The God of War, now in a mortal body, wants to cultivate again and take his wife back to the Temple of War. But an unexpected joy awaits him: his wife is pregnant! But fate is cruel once more. While his wife is resting during her pregnancy, she is murdered! Two lives lost at once! He will avenge this, no matter the cost! He'll make the murderer feel the same heart-wrenching, bone-deep pain! He gives up everything and exhausts all the cultivation he has accumulated in his life to open the Gate of Reincarnation for his wife, allowing her to be reborn with her memories intact. He then begins his cultivation anew, starting from nothing and rising step by step to become a king once more. When she turns eighteen, he'll help her become a goddess! Then it will be time for revenge...
