Time always passes too quickly. Without realizing it, Cynthia has already been home for three or four days—in other words, those two Melowa war prisoners have been locked in the Fourth District for three or four days.
According to previous records of prisoners' mental states, three days is the maximum time a highly resilient intelligent creature can endure in the Fourth District. However, it's said that those two Melowa prisoners have undergone comprehensive modifications, some even affecting the soul level, so perhaps they can last a bit longer? But I think it won't be much longer. Everything in the Fourth District is the result of Lilina's meticulous design; every criminal sent there receives "punishment" specifically targeting the mental weaknesses of intelligent beings. In the face of such extreme environments, mere brainwashing and mental fortification training shouldn't be too effective.
