After five days, Bian Que was going to visit King Huan, but he walked away when he saw King Huan from afar. An attendant of King Huan asked him why he was leaving. Bian Que said, “When the disease was in the muscles, medicine could treat it; in the blood, acupuncture could treat it; when gastrointestinal, medicinal liquor can treat it; but when disease is in the bone marrow, even the gods in charge of life cannot treat it! King Huan’s disease is in the bone marrow now, so I cannot treat it.”

After five days, King Huan was in pain and sent for Bian Que, but Bian Que had left. King Huan then died.
