The Sick Rice Seedlings I Randomly Picked up Are the World-Destroying Demons

[Two male protagonists | time travel development | black and white yandere villains | useless counterattack] Mu Ci traveled through time to study immortal literature, and he had the classic Wulinggen useless script in hand. He originally wanted to rely on Long Aotian's famous scene and wait for the system to come to his door. Unexpectedly, what comes from the sky is not to upgrade the golden finger, but to help the villain's face-slapping system. In the dilapidated handyman's hut, he picked up a young child Fu Yunzheng who was dying and whose spiritual veins were broken. System prompt: If you carefully raise this world-destroying demon king who will destroy the three realms in the future, you can redeem the cultivation skills; if he turns black and dies in advance, the host will be completely destroyed. At first, Mu Ci just wanted to catch fish and raise cubs to cultivate for ten thousand years, protect the poor little boy who was coughing up blood, protect him from the bullying of the sect, and use the tenderness of modern people to warm up a frozen demon heart cursed by heaven. He thought he was just the owner who controlled the fate of the villains, but little did he know that the little one had already regarded him as the only light in the world. When he grew up, everyone was afraid of Fu Yunzheng's overwhelming demonic aura, and regarded him as a disaster star that must be eliminated. Only this ordinary monk who came out of the courtyard dared to stand in front of the Demon Lord and protect him against all the laws of heaven. Fu Yunzheng leaned over and hugged him, with paranoid and pious tenderness in his eyes: "If everyone in the world wants me to perish, I will overturn everything in the world. Only brother, I will bow down forever."
