Guangyou chuckled, took a few steps forward, and said to Grandpa Wu in Chinese, "I want a skewer of candied hawthorns."

Grandpa Wu gently fanned himself with his palm-leaf fan: "Put the money on the table, then take it yourself."

Guangyou was not surprised. He took out the money and put it on the table. As soon as he turned around, Old Master Wu said, "Young man, you seem to be a little different."

His footstep faltered in mid-air. Guangyou turned back to the old man and smiled, "What did you say, Grandpa?"

Old Master Wu simply chuckled and said, "I am Wu Qingyun."

"Let's go." After saying his name, Wu Qingyun waved his hand, clearly not wanting to continue.

Since the old man didn't want to talk, Guangyou didn't have any other ideas, so he ate his candied hawthorn and took the subway back to his office.

After washing up, Kōyū opened the door to his room and the first thing he saw was Conan sitting by the bed. When Conan saw Kōyū come in, he asked, "How did you find Senma Kyōsuke? And why hasn't he turned into a skeleton all these years?"

According to Conan's knowledge, under normal circumstances, a corpse will harden within 30 minutes to 2 hours after death, become completely stiff within 9 to 12 hours, soften after 30 hours, and return to its original state after 70 hours.

If a corpse is exposed to air after turning into bones, it will quickly turn into bones within a few weeks to a few months due to the influence of maggots and air.

If the coffin is sealed, the skeleton will typically be completely decomposed within one or two years due to the isolation of most of the air.

However, Senma Kyosuke's situation clearly contradicts the knowledge he has learned.
