I Give the Unlucky Protagonist Who Transmigrated into a Book Cheat Powers

People transmigrating into books were running rampant, and the protagonists who should have been destined for success were having the worst luck. Not only were their lives stolen from them, but to eliminate any future trouble, their lives were taken too. The protagonists died in humiliation, their resentment shaking the Heavenly Dao and awakening vengeful evil spirits to help them get revenge. The princess, a hidden gem who would have become an empress and ushered in an age of prosperity, was sent away for a political marriage to beg for peace. She suffered endless torment with no one to turn to, and eventually died in despair. The student, who would have persevered through humiliation to become a pioneering figure in science and technology, was driven to a miserable death by the abuse and beatings of his tormentors, all in the name of a so-called "happy ending." The Immortal Venerable, who would have shaken the world with his sword, swept away the demonic miasma, and restored peace to the mortal realm, had his opportunities stolen by someone who transmigrated into a book. They then plotted to cripple his cultivation and destroy his meridians, forcing him to become their frail, pampered wife. Ying Yue: An eye for an eye, blood for blood. Professional revenge, fair and square. Just pay a small amount of merit, and I'll make sure you reincarnate with no regrets. P.S. The protagonist has no fixed gender and switches back and forth between male and female. P.P.S. The first world is like a prequel, with the protagonist still growing up and a beautiful big sister carrying the team. The protagonist takes center stage starting in the second world. P.P.P.S. The first two worlds were written almost entirely by a silly author in a state of inhaling coal gas. Um, the whole story is a bit messy, and I can't fix it anymore, so please bear with me _(:з"∠)_ Theme: Though battered by a thousand blows, remain steadfast; let the winds come from east or west, north or south., Zheng Banqiao
