Who can give me a 200-word summary of curettage and detoxification?

Guan Yu was once shot in the left arm by a flying arrow. Later, although the wound healed, his bones often hurt every rainy day. Hua Tuo said: "The arrow is poisonous, and the poison is in the bone. We should cut the arm (treat the arrow wound again), scrape off the bones infiltrated by poison, and (completely) remove the poison, so as to eradicate the disease. " Guan Yu stretched out his arm and let Hua Tuo cut it open. At that time, Guan Yu just invited the generals to drink and eat together, and the blood on his arm spilled on a plate, while Guan Yu (also) cut the barbecue (ate), raised his glass (drank) and laughed.
