Became a Failed Experimental Subject - Chapter 66: It’s a Bug

After causing a tech disaster in the real world, genius shut-in Rin Katsuro is sentenced by the gods and banished to Ereborn—a realm ruled by chaos, where ancient scripts control magic and dungeons feed on trauma.He wakes up in the body of a legendary war criminal—the Demon King's General—and is mistaken for the adoptive father of a demon princess.Armed with unstable “Error Magic” that lets him rewrite reality like code, Rin doesn’t want to be a hero... but when angels declare war on the demon races, and his daughter calls him “Papa,” he might just rewrite fate itself.This is the story of a broken man with nothing left to live for—until an entire world starts calling him Dad, Demon, and Destiny.

The army drillmaster Yu Xiaoxiao (玉小小) [aka “Little Jade”] transmigrated from a zombie apocalypse world into the body of the eldest imperial princess. On her first day, she got hitched to young General Gu Xinglang (顾星朗) at the lowest point of his life: unjustly accused, imprisoned, and tortured. Ever since then, the valiant girl who only knew how to eat, sleep, and fight zombies tied her destiny with the brave general who was loyal, patriotic, stern, and taciturn.

With the country weak and enemies on all sides, the imperial palace is full of spying concubines, sycophant officials, and a fatuous, self-indulgent ruler. Beyond the court lies the populace suffering in dire poverty. Faced with these circumstances, General Gu only hopes that he can help the imperial court restore its discipline and give peace to the people.

But his wife and princess says, “Your wish is too grand. Let’s go take over the kingdom ourselves instead!”

“…….” General Gu could only remain speechless.

How does one become a royal favored by the annals of history? Yu Xiaoxiao is convinced that a truly good princess is one who dotes on her husband!

The Fourth Brother had squandered his wealth through gambling, leaving their mother in a critical state. To make matters worse, the creditors even asked them to sell Manbao to settle the debts!In the village, whispers spread that the golden days of the Zhou Family's cherished Manbao were over. Their elderly mother clung to Manbao's hand, tears streaming down her face.However, Manbao tightly grasped a system in her hand, a tool that would lead her and her brothers and sisters-in-law to reclaim their fortunes. They ventured into agriculture, cultivating land, growing medicinal herbs, and establishing shops, steadily improving their lives.As their situation improved, concerns shifted to Manbao's marital prospects by the sister-in-laws.“Mr. Zhuang's grandson is an excellent match – educated and well-spoken. He is just perfect for you.”“No! You should consider Mr. Qian's youngest son, who is handsome and well-mannered. You can count on him never to defy you.”Suppressing a smile, Manbao responded, “My heart is already set. I choose Bai Shanbao, my childhood friend whom I've playfully scolded since we were young.”

The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious. When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before. At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!
