Conan's physique? The Crown Princess is involved in a murder case again

After Xu Xingyin answered, he took out a piano score from his arms and placed it in front of Jing Zhichen.

"Yesterday I asked Mei Hanrui a question. Do you still remember the third section of Kong Hou Yin?"

Jing Zhichen didn't even open the cover of the music score, but glanced at Xu Xingyin with a chuckle.

"Are you deceiving others again? There is no third section in Kong Hou Yin."

"Yes, look, if even His Highness knows this, how could Mei Hanrui, who is an excellent zither player, not know it?"

Xu Xingyin answered as a matter of course.

Jing Zhichen frowned in dissatisfaction, "Even I know about this?"

Xu Xingyin quickly explained, "What I mean is that 'Kong Hou Yin' is an advanced course in qin art. With Mei Hanrui's attainments, she should not be unaware of it."

"My piano skills have made some progress. Princess, do you think I don't know this?"

Xu Xingyin held his forehead helplessly, feeling powerless to deal with the unreasonable demands.

"Your Highness is knowledgeable and talented. Who doesn't know that? Not to mention the Konghou Yin, even the Nine Heavens Mysterious Music can't stump you!"

Xu Xingyin suppressed his frustration and said a few words to smooth things over before getting back to the main topic.

"There is one more thing that I couldn't figure out earlier, but if Mei Hanrui's identity is fake, then everything makes sense."

"What's the matter?"

"Your Highness, do you remember that when we went to Shizhuwan to rescue people, Mei Hanxuan wrote down the intentions of those thieves on the ground? But I clearly saw that the strokes were in the wrong order when she wrote them! At that time, I thought she was frightened, so she wrote the wrong words, but now I think, could it be that she had always been like this?"

Xu Xingyin's words reminded Jing Zhichen of another thing.

"Then Princess, do you still remember that on the way back to the capital, you casually quoted the line 'The climate in the south of the Yangtze River is different, winter rain turns into spring chill', and Mei Hanxuan praised you for your literary talent."

Thinking about it this way, Xu Xingyin became more certain of his guess, but as he thought about it, he felt something was wrong.

So, he turned around and asked Jing Zhichen.

"Didn't Your Highness and I go separately on the way back to Beijing? How do you know this?"

The sudden question made Jing Zhichen choke, and his ears turned red.

"I... this palace is naturally... in order to investigate the original pursuit, so I naturally want to know everything that happened along the way!"

There was still doubt on Xu Xingyin's face, but this... wasn't it too detailed?

Jing Zhichen lowered his head and took a sip of tea, avoiding Xu Xingyin's gaze, and calmly changed the subject.

"So, the talented girl made a mistake in writing characters, and the zither player didn't recognize the music. These two sisters are either fake, or they are..."

Xu Xingyin interrupted, "Identity exchange!"

Jing Zhichen nodded and asked again: "Since you already have the answer, what else do you want to ask me?"

Xu Xingyin frowned and said, "I only know this, but I'm afraid I can't pry open the mouth of the man in the dungeon. So I came to ask Your Highness if there is any good way to interrogate him?"

Jing Zhichen responded, "You would rather sacrifice your sister than save your own people. How selfish and cold-hearted you are. Why would you risk your life to target someone like you who is obviously difficult to deal with? Crown Princess, why don't you think about it from this perspective again."

Xu Xingyin frowned even deeper and muttered depressedly.

“Isn’t this going back the same way?”

Jing Zhichen looked at Xu Xingyin's extremely distressed expression and gave him a kind reminder.

"I heard that Mei Hanrui rarely went out since she started living in the Duke's Mansion. But the few times she went out, she always went to the same street."

"where?"

“Zhuangyuan Hutong.”

Xu Xingyin was a little puzzled, "What is there to see in Zhuangyuan Hutong?"

Zhuangyuan Hutong is a very prosperous street in the capital.

Because of the pleasant name, even though the rent is quite high, it is still very popular among scholars.

Jing Zhichen shrugged and said, "Perhaps if you figure this out, you will know Mei Hanrui's weakness."

Xu Xingyin seemed to understand, but it was not good to delay Jing Zhichen's business any longer, so he said hello and left.

After leaving Jing Zhichen's study, Xu Xingyin thought about it for a long time but still couldn't figure it out.

Finally, he simply changed into casual clothes, left the palace and strolled around Zhuangyuan Hutong.

Zhuangyuan Hutong still looks the same as it did before Xu Xingyin entered the palace. The alley is mainly residential and the few shops are unremarkable. The customers are all residents in the surrounding area.

As for those who came here specially from other places?

Rare!

As Xu Xingyin was strolling, he bumped into someone head-on—

Lu Xu.

Perhaps he didn't expect to meet Xu Xingyin here. Lu Xu was stunned at first, but after he came to his senses, he subconsciously pulled Xu Xingyin and hid in the gap between the houses.

"I heard you fell off a cliff? Are you injured?"

Xu Xingyin shook his head and answered honestly, "Don't worry, I'm fine. It's His Highness who is seriously injured. It looks painful to see."

Hearing Jing Zhichen, Lu Xu was obviously not very happy and responded sullenly. "You are thinking about him."

"what?"

"nothing."

Xu Xingyin didn't quite hear what he said, but Lu Xu just waved his hand and changed the subject.

"After all, His Royal Highness the Crown Prince is in a high position, and there are countless people who hope that he will be in trouble. Although you and His Royal Highness the Crown Prince are not a real couple, outsiders may want to use you to threaten His Royal Highness the Crown Prince. You must not travel so rashly in the future. At least bring one or two people who can protect you with you. Besides, the mastermind behind the last cliff fall has not been caught yet..."

Upon hearing Lu Xu's chattering, Xu Xingyin quickly stopped him.

"I already have an idea of ​​who is doing this."

Lu Xu immediately shouted angrily, "Who is it? Has he been detained? Don't let him fall into the hands of our Jinyiwei, or I will make him lose a lot of skin!"

Xu Xingyin curled his lips and said a name clearly and concisely.

"Mei Hanrui."

Lu Xu was stunned. "She? How could it be?"

Xu Xingyin was also a little surprised by Lu Xu's reaction, "Why, you two are very familiar with each other?"

As if afraid that Xu Xingyin would misunderstand him, Lu Xu quickly waved his hands.

"Not really, it's just that Mei Hanrui was asked by my aunt to come and bring me cakes a few times before."

"pastry?"

Lu Xu nodded sincerely, but Xu Xingyin looked at Lu Xu suspiciously.

Why would mother send cakes to Lu Xu for no reason?

If Xu Xingyin remembered correctly, her mother had specifically reminded her two days ago to have less contact with Lu Xu to avoid any gossip.

Since the mother had this idea, why would she take the initiative to contact Lu Xu?

Lu Xu did not notice Xu Xingyin's confusion, but scratched his head uncomfortably.

"Since you are all out, how about I treat you to a simple meal?"

After Lu Xu finished speaking, Xu Xingyin suddenly came to his senses and politely declined Lu Xu.

"No, I have something important to do and need to go back to the Duke's Mansion. Maybe next time."

Lu Xu felt a little disappointed when he heard this, but he had no right to try to keep him, so he replied dejectedly, "Okay."

When he raised his head again, Xu Xingyin had already disappeared from his sight.

After bidding farewell to Lu Xu, Xu Xingyin quietly returned to the Duke's Mansion.

My status is different now. If I return home rashly, it will only cause more trouble.

Therefore, Xu Xingyin didn't even meet Chen, but only secretly asked Chen's personal nanny Gu to confirm what Lu Xu said.
