"Like a rusty machine, the bones of the whole body are rubbing and fighting, torturing the mind."

Now I'm thinking about how to alleviate his pain:
1. Inject him with anesthetics;
2. Use paralysis powder on the painful parts;
3. Use sleep powder to put him into a coma.

But I don't like it and I can't use a syringe. I don't have a lot of paralysis powder. Sleep powder, his whole body pain will make him want to sleep and can't sleep, aggravating his pain. I need more choices, and it sounds the best…
