Curing Mental Illness Will Make You Stronger? I'm Crazy

This is a world where only mentally ill patients can awaken supernatural powers. Aliens invade and humans rise up to resist. People with schizophrenia can awaken one or more clones, each with different abilities. Social phobia can awaken the ability of invisibility, fear of heights can awaken the ability to fly, mania can transform into a giant with infinite strength, Alice's sleepwalking can change the size of objects at will... Not only humans have mental patients, the more advanced the abilities of aliens, the more severe their mental symptoms are. Lin Fei, who suffered from severe claustrophobia, traveled through time and brought his own mental healing system. Every time he cured a mentally ill patient, he could collect payment from the other party. Not only could he directly rob the patient of his abilities, but he could also sign a master-servant agreement with the other party. The most important thing is that he can detect increasingly rare mental patients in advance before everyone else, and accurately help them awaken. Loot the abilities of monsters, subdue the alien slaves, and lead the elite human superpowers to hunt the alien masters behind enemy lines! This is the story of a psychopath leading a group of psychopaths to save the world...
