Heat Death Daughter

The IPCC predicts that the global average temperature will rise by 4.4°C by 2100. It's the year 2163, and civilian thermometers only show black when they exceed 42°C. Humanity has built the Yuan Brain, a quantum supercomputer suspended in orbit, responsible for global heat dissipation. The optimal solution it found was to incorporate emotions into the cooling system: fear crystallized into fuel, and warmth smelted into glue. Seventy percent of human beings cut off their emotions and ascended to the resting layer, while the rest stayed in the cracks of the heat dissipation pipe network and became "herders", using their emotions to survive. Ava Klaus, the best herder in Sector 7. She comforts the dying with her smile, and harvests the Dread Crystal Clusters with her actuarial calculations. Embedded in the heart is a relic of his parents - a key that seals a purely mechanical cooling solution. It requires real emotions to maintain its activity and is the only blind spot of the brain scanning system. The sector dispatched Martha to kidnap twelve children and throw them into the resonance pool. Ava only has two weeks left to carry the key and break into the orbital core, forcing a switch to the cooling solution - at the cost of permanently burning her emotional center. She calculated all the probabilities, and the success rate was less than 10%. The only thing she didn't figure out was why she could still feel her heart burning as she walked towards the core cabin. Yuan Nao projected herself into her mother's appearance and asked, "You will kill tens of millions of people, why are you still pressing it?" She pressed the key into the slot: "Because they will remember that the heat is theirs." Then she pressed it. The earth is starting to get hot again.
