I Became the Big Shot's Mermaid in the Palm of His Hand

Su Yuquan transmigrated into a book. In the story, he was a cannon-fodder love interest. Because his father sacrificed his life to save the Marshal, Su Yuquan was married off to the Marshal's son in return. From then on, the cannon-fodder love interest clung to the male lead and refused to let go. He kept interfering with the male leads' romance, and in the end, the male lead sent him to a brothel in the black market, where he met a horrific death. Su Yuquan didn't want that ending. But the force of the plot ruthlessly pushed him into the whirlpool, turning him into a stepping stone for the main characters. Su Yuquan fought back for three lifetimes, but each attempt ended in failure. In his fourth life, he gave a cold laugh and jumped straight into the sea, intending to drown himself. If he was doomed to be a stepping stone no matter what, he might as well kill himself first. However, after jumping into the sea, he unexpectedly awakened his ancestral genes in this life! He grew an ice-blue fish tail and became the only mermaid in the world. Heh, the plot really was tenacious. But he still didn't want to be a stepping stone! He immediately thought of the final villain, the former emperor. Su Yuquan swam to the bottom of the sea and brought the man up. The insect queen had yet to be killed by the male leads, and the war against the Zerg was still raging. The former emperor's influence was still intact, so Su Yuquan would wake him up ahead of schedule! Then he could help him kill that scumbag, the male lead. The emperor, tormented by mental storms, passed away. Countless citizens placed him in an ice coffin and sank it to the bottom of the sea, hoping he could rest in peace alongside the ocean he loved most. From then on, the royal family gradually declined, and the Marshal shouldered the heavy burden the emperor had once borne, vowing to wipe out the Zerg. But the deceased Andrew awoke from his slumber, still irritable and eager to destroy everything because of his mental storms. He opened his eyes. A face pure and innocent was pressed against the ice coffin, blinking curiously at him.
