The Cannon Fodder's Revenge [Quick Transmigration]

Lin Yanqing had just received his admission letter from the country's top university when he kicked the bucket. Just after dying, he was bound to a Cannon Fodder Comeback System. Just after being bound, he learned he was nothing but an unlucky little cannon fodder in a novel. Then he was tossed into some kind of cannon-fodder comeback mission. He was utterly dumbfounded the whole time. ???? Who am I? Where am I? In a cultivation harem novel, he was the playboy younger brother of one of the protagonist's harem members. He treated his sister wonderfully and repeatedly clashed with the harem-seeking protagonist for her sake, only for his lovesick sister to turn around and help the protagonist wipe out his entire clan. ???? A piece of trash like that is wasting food just by being alive! Just wait till I cultivate some immortality. I'll punch that pair of scumbags into oblivion! In a rebirth novel about a rich girl, he was a golden phoenix who had flown out of a mountain ravine. In his previous life, he had tricked the "innocent" rich girl out of her "family fortune," so the reborn heroine and her CP ruined his reputation and left him with nowhere to go in the world. ???? Hah! Who wants your lousy fortune? Just watch me grow a field of spirit crops and make a name for myself in business! In a period novel, he was an unfeeling, faithless educated youth sent down to the countryside. To avoid hard labor, he seduced the brigade leader's youngest daughter. But after getting into college, he abandoned his wife and child and returned to the city, where the protagonist put him in his place. ???? He's so handsome, while the brigade leader's daughter is burly and broad-built. So which of us seduced the other, really? Or was she the one forcing herself on me? And there's more... Wait! Why does every one of these cannon fodder characters have it worse than the last? Warnings: The writing is amateurish, the logic is nonexistent, and the story is just about having fun. The romance is a minor element. Theme: Things go wrong nine times out of ten in life. Better to rely on yourself than on others.
