Demon Slayer: the Immortal Water Column Under the Fox Mask

On the night of the final selection, Qiang Tu should have died at the hands of the ghost. But the second before the fox mask shattered, he bound a ghost hunting terminal that only cared about efficiency and not about human life. It can analyze ghost blood, calibrate breathing, and accurately point out the half-inch deviation of the blade. But she would not heal his injuries, nor would she wield a knife for him. That night, the Hand Ghost died, but the Qiang Rabbit survived. But surviving is just the beginning of cruel calculations. In the terminal's field of vision, ghosts are samples to be eliminated, and swordsmen are expendable numbers. In desperate situations, it can always give an absolutely rational "optimal solution" - giving up the seriously injured and giving priority to killing evil spirits. Qiang Rabbit does not. He wants to kill ghosts, but also save people. He wanted to let the exhausted swordsmen hold on until reinforcements arrived, to let those who were dragged into despair live to see the light of day, and even more to let the deaths originally written on the monuments open up another possibility. When the red warning on the terminal flashed crazily and the optimal solution "It is recommended to give up" popped up again, Qiang Tu wiped the blood from his jaw and held the damaged Sun Lun Knife tightly. "Recalculate." "Count until everyone is alive!" The introduction is too weak, please move to the main text.
