I Am Practicing Magic in a Mental Hospital

Fang Chen got brain cancer and only had three months left to live. But an inexplicable note, coupled with the mentality of treating a dead horse as a living horse doctor, actually led him into a weird world of cultivation. After traveling back and forth between the two worlds for a long time, Fang Chen couldn't even tell which was true and which was false. The ravings of madmen in mental hospitals may be "secrets" from another world. A simple bottle of painkillers may also become a "cure-all" elixir. Everything he does is reflected in a different way in another world. And he seems to be the only bridge between these two worlds. "Mr. Fang, your tumor has shrunk by half a centimeter. This is really a miracle." "But you need to pay attention to your mental problems." "Why is there a giant toad half as tall as a man in the hospital?" "Yes, you have to call it Mr. Hei."
