The Villainous Cannon Fodder's Fiancé [Book Transmigration]

[...] Bai Lihan had read a modern urban cultivation novel about a heroine who steadily leveled up. She was cold and aloof throughout, yet countless men who admired her independence and strength eagerly offered her opportunities and resources. The heroine called herself "self-reliant and strong," "cold as ice," and someone who "didn't believe in love," all while accepting gifts from other men without hesitation. Bai Lihan transmigrated into the book as one of the heroine's men: an "idiot" who deceived his own betrothed male spouse to win the heroine's favor, then spent his entire fortune just to catch her eye. Bai Lihan: ... Looking at the antique necklace he hadn't given away yet, Bai Lihan decided to stay far away from the heroine. But when he turned around, he saw his own betrothed Shuang'er: the male spouse who would later stab a scumbag hundreds of times before slitting his own throat. Unfortunately, the top hadn't read that far. Bai Lihan: ...He's so cute. Bai Lihan: It was love at first sight. Bai Lihan: How about we cultivate immortality together? Xia Changming: ... Xia Changming: Sure~ After they got together Bai Lihan: ...Help! What do I do when my lover is so possessive and keeps threatening to kill me?
