contract marriage to my ex's best friend novel

From an apocalyptic world, Xu Feng transmigrates into a parallel world with a third gender. The heavens took pity on the 19-year-old who died as he awakened his ability in his original world, so he started a new life as a ger. What is a ger? The third gender, a man who can impregnate women and be impregnated by men. There were even more surprises waiting for Xu Feng. He not only awakened a wood ability from his previous world, he was also met with a contract marriage he couldn’t refuse in the new world. “Carry my son’s child, and I’ll make sure you live comfortably for the rest of your life.” “Whether you can birth a son for me or not, I don’t care. Just don’t get in my way, and I’ll make sure you want for nothing.” Xu Feng looked at his “mother-in-law,” then back at his "playboy" of a “husband” before looking toward the fertile fields and vast mountains. A peaceful farming life as a landlord with a spoiled young master was better than living life in the apocalypse. But Xu Feng was transported to a world with cultivation, demon beasts, and hidden secrets, a simple farming life might be too much to ask for. — [Cultivation, Farming, Multiple partners/Throuple, BL, R-18, Child, HE]
