An Xuan.

The person the little beggar drew was An Xuan.

After throwing away the branch in his hand, the little beggar huffed and rolled up his sleeves, revealing several bruises.

Now the situation was quite clear. An Xuan had somehow caught the little beggar, not only snatching the brocade pouch from his waist but also giving him a good beating.

Jiang Cheng immediately recalled his first meeting with the little beggar. An Xuan had pretended to be careless and let the little beggar go, presumably because he had already formed other ideas about him, but it wasn't convenient to act with so many people around.

On the night the little beggar came to deliver the message, Jiang Cheng had glimpsed the brocade pouch at the little beggar's waist in the moonlight, and this pouch was exactly the same as the one on the woman in the painting.

At the third watch, the boat travels on the moonlit water, half a su nang can soothe the sorrow.

The su nang in the second half of the line must refer to this.

"Doctor," Fatty said, thinking for a moment, "that An Xuan doesn't seem easy to deal with. It might be difficult to get the brocade pouch back from him."

Hearing Fatty's words, the little beggar suddenly changed his expression. He raised his head, lifted his small face, squinted his eyes into slits, and waved his hands at Fatty repeatedly.

Fatty looked at him in confusion, wondering what was wrong with this little beggar...

Then the little beggar made many gestures at Fatty, but unfortunately, he couldn't speak, and Fatty's eyes hurt from trying to understand, but he still couldn't make heads or tails of it.

In the end, the little beggar seemed a little helpless.

"Are you saying that it's okay that person snatched your brocade pouch?" Jiang Cheng looked at him and said, "Because that brocade pouch was fake, and the real one... is still on you?"

The little beggar paused, then stared at Jiang Cheng warily, covering the lower part of his chest with his hand and slowly backing away.

Fatty seemed to suddenly realize something and quickly waved his hands at the little beggar, saying, "Little brother, he's a good person, much better than me. You can tell him anything; it's the same as telling me."

Afraid that the little beggar wouldn't understand, Fatty pulled Jiang Cheng over, put his arm around Jiang Cheng's shoulders, and hugged him close, looking very intimate, as if they were about to take a picture.

"Look," Fatty said, "we're very close. I've always treated him like my own brother."

Jiang Cheng's brow twitched.

Fatty's actions seemed to finally have an effect. The little beggar looked at Jiang Cheng for a while, then looked at Fatty again, and then reluctantly nodded, his expression seeming to say that he was only paying attention to Jiang Cheng for Fatty's sake.

After a long while, the little beggar slowly took out a very small object from his bosom.

The moment they saw this object clearly, the expressions of both Jiang Cheng and Fatty changed.

It was a broken brocade pouch.

The color was exactly the same as in the painting.

But this brocade pouch seemed to have been torn violently, so only half of it remained, and there seemed to be some words embroidered on it.

This was the half a su nang...

Upon discovering that Jiang Cheng was staring at the brocade pouch in his hand, the little beggar subconsciously wanted to take the pouch back.

Jiang Cheng quickly poked Fatty in the butt.

Fatty immediately understood and said to the little beggar, "Why is only half of this brocade pouch left? Was the other half..."

The little beggar showed great enthusiasm toward Fatty. He gestured repeatedly at Fatty, and gradually, the little beggar's eyes turned red, and he looked very aggrieved.

"Are you saying that the other half was snatched away by this person?" Jiang Cheng pointed to An Xuan's portrait on the ground and said, "He and a woman caught you, and in the struggle, they tore your brocade pouch and snatched away the other half."

The little beggar nodded repeatedly.

Fatty, who was completely confused, couldn't understand how the doctor had deduced so much information from the little beggar's actions. Could it be...? Fatty's eyes widened.

Was this the legendary tacit understanding between orphans?

Did they have their own communication system that ordinary people couldn't understand?

"I understand your request." Jiang Cheng nodded very formally to the little beggar, whose eyes were red, and said, "I can help you, but I need the brocade pouch in your hand. It's very important."

The little beggar swallowed and showed a very conflicted expression.

Jiang Cheng glanced at Fatty, who was staring blankly at him, then turned his head, pointed at Fatty, and said to the little beggar, "You saw just now that this Fatty and I are very close. I've always..." Jiang Cheng stiffened his neck and suddenly said, "I've always treated him like my own son!"

Fatty: "???"

The words "own son" seemed to touch the little beggar. After looking at Fatty and then at Jiang Cheng, the little beggar handed the remaining half of the brocade pouch to Fatty.

This brocade pouch seemed to have great significance to him. He held it tightly with both hands and finally made up his mind to let go.

After taking another reluctant look at the brocade pouch in Fatty's hand, the little beggar climbed over the wall and left.

"Doctor," Fatty asked curiously as they walked on a gravel road, "who exactly is this little beggar? How does he have the female ghost's brocade pouch?"

"And... and he knows a lot of secrets." Fatty continued, "He must have been here for a long time."

After a moment, Jiang Cheng's voice rang out, and his first sentence made Fatty stop in his tracks. "He's not a beggar. He was probably the female ghost's personal servant when she was alive."

"Servant?"

"Yes." Jiang Cheng nodded. "She's a woman. I think after the female ghost died, no one took care of her anymore, so she became like this."

"Although her clothes are dirty, the material is quite good. She wouldn't be an ordinary servant. And did you notice the painting she drew?" Jiang Cheng continued, "Although it looks simple, you can still vaguely see some skill in it. And the character 'huang' she wrote showed a relaxed style. Ordinary beggars wouldn't have the leisure to learn these things."

"One more thing, she's not afraid of ghosts." Jiang Cheng's tone became heavier. "She actually dared to watch a play by the lake alone at night."

"And if you calculate her age, her familiarity with this place, and the fact that she possesses the brocade pouch carried by the female ghost in the painting," Jiang Cheng said, looking at the half of the brocade pouch in his hand, "her relationship with the female ghost should be very close. The probability that she was the female ghost's personal servant when she was alive is very high."

Fatty listened in a daze, but following the doctor's line of thought, and connecting the brocade pouch, the thirteen or fourteen-year-old girl, not being afraid of ghosts, being familiar with the terrain here, and knowing many secrets about the female ghost... the doctor's speculation didn't seem so abrupt.

Not only was it not abrupt, it was simply very reasonable.

"So..." Fatty said excitedly, "the half a su nang in the code... is this?" He stared at the brocade pouch in the doctor's hand, swallowed, and said, "With this half a su nang, we can solve our current confusion."

"It should be."

"Wait a minute, Doctor," Fatty said in confusion, "then what about the half that An Xuan and the others snatched away?"

Hearing this, Jiang Cheng chuckled. "Then I wouldn't know."
