If Heaven Is Unjust, I Will Become Stronger Than Heaven

The Cai family’s courtyard had once been filled with laughter. Cai Heng remembered it clearly. He was born into a cultivator family that lacked nothing—neither resources nor love. His father, Cai Yuan, a Golden Core cultivator whose name echoed across battlefields. The world called him “The Apollo of the War Room”, a man whose arrows decided the outcome of wars before swords ever crossed. His mother, Madam Li, came from a neighboring medical sect, her hands capable of pulling people back from the brink of death. She was gentle, sharp-minded, and already at the second stage of Golden Core. For five years, Cai Heng was their only child. Then his little sister was born. From that day onward, the Cai residence overflowed with warmth. His sister would cling to his sleeves, babbling nonsense while their parents watched with smiles that never faded. Cai Heng trained hard, not out of pressure, but because he wanted to protect that warmth forever. The Cai Clan was strong. All nine elders were Golden Core cultivators. The clan head and the grand elder had already stepped into the Nascent Soul realm. The future seemed stable—unyielding, even. Then heaven cracked. Cai Heng was twenty-eight when it happened. He stood at the edge of a breakthrough, spiritual energy surging violently within him. His core was shining, a breaktrough was within reach. That was when the sky split open. Above the clouds, existences beyond mortal comprehension clashed. Laws shattered. Lightning tore through space itself. No one understood why gods fought—or why their battle descended upon the surrounding lands. They never needed to. Because the result was annihilation. Mountains collapsed. Formations shattered like glass. Golden Core cultivators—once invincible in the eyes of mortals—were erased in seconds. By the time the heavens quieted, the Cai Clan was gone. Only seven lived. Cai Heng. His little sister. And five other clansmen, all barely clinging to life. They fled. With ruined families, clan, they escaped to a small, insignificant mortal country, hiding their identities and opening a modest tavern. They brewed cheap wine, cooked simple meals, and tried to bury the blood staining their past. They knew who stood at the peak now. The Taiyi Sect. Jade Pure Palace. Those two powers rose after the divine battle—far beyond anything the remnants of the Cai Clan could challenge. So they endured. They swallowed their hatred. They waited. Three years passed. Against all odds, Cai Heng and two of the surviving brothers broke through to Golden Core. It was weak. Unstable. But it was hope. For the first time since the clan’s fall, they believed the Cai name might live on. Five months later, that hope was crushed. The visitor arrived on a bright afternoon. He wore the unique Taiyi Sect robes—clean, arrogant, unmistakable. From His robes, they could tell His position, inner sect disciple. He drank their wine, mocked their accents, and laughed at their insignificance. Cai Heng thought, it's alright, they were insignificant, the man was just passing by. Then he revealed the truth. “Loose ends,” he called them. “Potential threats.” “A future inconvenience.” The decision had already been made by the upper echelons. The Cai remnants could not be allowed to grow. The tavern became a slaughterhouse. Cai Heng fought. Golden Core against Golden Core—but the difference in foundation was absolute. His brothers fell one by one. The remaining survivors were subjected to atrocities too cruel for words, their dignity and lives stripped away simply because they were weak. Cai Heng was left alive. Not out of mercy. But because despair amused them. When the bodies cooled and the blood dried, he lay broken among the ruins—meridians shattered, dantian cracked, consciousness fading. Hatred burned brighter than pain. Hatred for the heavens. Hatred for the so called righteous and demonic sects. Hatred for strength he never had. That was when a voice echoed in the void. 「Binding complete.」 「System 77 online.」 Cai Heng laughed weakly. “A system?” he rasped. “Now?” The voice was calm. Mechanical. Unemotional. 「You have witnessed unjust deaths across multiple worlds.」 「Your soul resonates with resentment strong enough to pierce dimensional barriers.」 「Contract offered.」 Images flooded his mind. Countless people crushed by fate. Families erased. Lives ended not by weakness—but by unfairness. 「Assist the unjustly dead across small worlds.」 「Complete main and side tasks.」 「Accumulate System Points.」 Cai Heng’s breath hitched. “And then?” A pause. 「Upon reaching sufficient accumulation, you may activate a Time Reversal privilege.」 「Target: Your teenage years.」 Silence. Then Cai Heng clenched his shattered fist. He did not ask about morality. He did not ask about mercy. He asked only one question. “How strong can I become?” 「As strong as you are willing to go.」 A smile—cold, feral—spread across his bloodied face. “Good.” “If I must walk through countless worlds… If I must carry the grudges of the dead…” His eyes burned with resolve. “Then I will return.” “And when I do— the Taiyi Sect and Jade Pure Palace will learn what it means to fear potential.”
