The sudden sound frightened Qin Songen and Song Yuban, and the two of them looked up together, and they couldn't help but breathe a sigh of relief when they saw that it was just the sound of a lantern blown by the wind.

Qin Songen nodded at Song Zhuban and said solemnly: "I understand, don't worry." ”

But when he thought of what Qin Songen was going to do, Song Zhiban also had to sweat for her, and he could only silently watch Qin Songen stride forward.

However, Qin Songen and Song Zhiban measured how to break into the front for a long time, who knew that it would be so coincidental, when Qin Songen passed, He Chaozhi had already finished talking with Pei Ruchu, and the two were pacing out of the room.

Pei Ruchu sent He Chaozhi to the intersection and happened to have a face-to-face with Qin Songen.

Although Qin Songen had never seen He Chaozhi before, he thought that he could walk in front of Pei Ruchu and was accustomed to it, and his face did not change, except for the little emperor in this palace, it is estimated that there is only this Prime Minister He Cheng who entered the palace early in the morning to discuss.

Although his appearance is not as graceful as Qin's father, he can be properly maintained, and because he is now in power, although there are still one or two "little things" that are unpleasant, but in general, it is the situation at the peak of life.

If he wants to make progress, it will be a change of dynasty, but now such a national situation, I am afraid it is not a good time, it is better to be a "shadow emperor" of Ye State, so Qin Songen saw that although he made a restrained and modest appearance, but those sharp eagle eyes could not deceive people, it was a man who was very city and decisive.

Qin Songen also knew that now was the time to "pretend", so Ying Ying half-squatted and saluted them, of course, the focus was on "him".

Sure enough, He Chaozhi stopped, stood on the steps, looked down condescendingly, and asked Pei Ruchu, "Who is she?" ”

Pei Ruchu glanced at Qin Songen and said lightly: "Shushen Xiangjun." Seeing that He Chaozhi hadn't reacted yet, he added, "The eldest daughter of the Qin Shilang family." ”

He Chaozhi nodded, and looked at Qin Songen with an amiable elder: "It turned out to be the pearl of the Chengjin family." He paused, smiled and asked, "Did you wait here for me on purpose?" ”

Qin Songen was also stunned for a moment when she heard this, and immediately reacted again, it turned out that her father was sincere and sincere, and Pei Ruchu finished his words, which was really funny: Qin Lian was neither sincere nor cautious; Pei Ruchu is 108,000 miles away from the complete "me", does he look at his words every day? I don't know who took their words in the first place.

But now is not the time to slander, Qin Songen's mind turned slightly, and he hurriedly pulled his thoughts back: "Yes, it's not." She laughed.

He Chaozhi was also a little interested when he heard this, and his originally not very good mood suddenly became a little smiling: "Oh, do I have a share too?" ”

Qin Songen said with a straight face: "That's right, for what happened in Qionghua Garden, the little girl has a little bit to tell the two adults, Miss Fang is afraid that she is being framed, she may not be playing tricks and pretending to be ghosts." ”

He Chaozhi and Pei Ruchu stayed in the room for a long time, they were just having a headache about this matter, he didn't care much about Qin Songen, but he felt that Qin Songen was a good-looking daughter of a capable subordinate, and when he first held power, he was the first to be pushed out by his father to be his icing on the cake, so he was also happy to give her face, so as to set off his approachability, Corporal Lixian.

But since this little girl dared to say in front of everyone that there was evidence to explain the night cry that everyone in Qionghua Garden heard and heard, He Chaozhi couldn't help but raise his eyebrows, wanting to give her some patience.

Just as Song Zhiban worried, He Chaozhi is in power, and now it is not like when he first fought for power with the Lord and the faction to muddy the water in the pond and fish, now that he is in the light and the earth is in the dark, he attaches more importance to a stable word, and does not want to have more twists and turns.

Fang Jizu is a stable and acquaintance, he has already secretly voted for him, if this matter is not so big, He Chaozhi will not be involved in the Fang family daughter by Pei Ruchu, the news of the poisoning case in the palace is known to the Wan people, and now the war between Dawan and Xichang is about to end, Dawan Iron Cavalry has broken through the royal capital of Xichang, the Xichang Emperor died of worry on the way to escape, the prince successfully escaped into Wei, but the fate waiting for him is not to think too much,

It's just that now that the weather is getting colder, I'm afraid it's inconvenient to go on the road, He Chaozhi has already made a decision with Dawan's envoys, and these women will be sent to Dawan in the spring of next year, so naturally they want to end the matter quickly.

Because Dawan people are staring at each other, they must catch the real murderer, so He Chaozhi does not dare to blatantly shield Fang Jizu, and now that he hears Qin Songen's words, He Chaozhi is already thinking in his heart, no matter whether she is reasonable or not, as long as she has the slightest chance, she can make it true for her.

So he made a patient appearance, Pei Ruchu sighed secretly in his heart, and could only listen to Qin Songen with He Chaoyi.

Qin Songen blessed his body: "Please come with me." ”

She took He Chaozhi, Pei Ruchu and other people to the smooth and neat wall of Qionghua Garden, which surrounded the entire garden in half a circle.

Now that she has received He Chaozhi's approval and Pei Ruchu's acquiescence, Qin Songen has a lot of manpower to do things for her.

She led everyone to stand in front of the wall, and Pei Ruchu made a strange voice impatiently: "What are you taking us to see?" ”

Because he had already done this experiment in Song Zhiban before, Qin Songen was able to joke with him very relaxed at this time: "A miracle." ”

Pei Ruchu rolled his eyes.

However, before his eyes fell, he heard a sudden melody from the wall, which became more light and ethereal as it passed through the empty and long alley.

"What is this?" Everyone couldn't help but be stunned.

Qin Songen raised his hand: "As you heard." ”

"But... This... How can there be music coming out of the walls? An attendant standing beside Pei Ruchu couldn't help but ask.

He Chaozhi also had such doubts, if he didn't know that Pei Ruchu's inner servants knew everything about the proportions of the harem, he would have thought that this Qin Songen deliberately hid people behind the wall, but he saw that Pei Ruchu and the internal attendants were confused, and they didn't know what was going on, so they couldn't help but chuckle, it seems that this Qin Songen really has a few brushes, and the township monarch who he called someone to seal originally thought it was just an additive, but he didn't expect it to be a dusty pearl.

Pei Ruchu coughed, as if with a little displeasure, interrupting He Chaozhi's thoughts: "What does this have to do with the case of Qionghuayuan, I think you are playing tricks and pretending to be ghosts, do you want to go with the Fang family?" ”

"Hey, don't be impatient, let's listen to the countryman's explanation together." He Chaozhi persuaded with a smile.

Qin Songen was not annoyed, and smiled at He Chaozhi and Pei Ruchu: "Please go to another place with me." ”

Everyone walked along the wall, and all the way they could hear the faint sound of ethereal music in their ears, and a few of the smarter ones had thoughtful expressions on their faces, as if they had vaguely guessed something, but they were still confused as to why this was so.

When Qin Songen took He Chaozhi, Pei Ruchu and others to the foot of the mountain where Fang Qing was found crying that day, they saw that the Yuefu woman invited by Qin Songen was playing here, and the music they played was the music they had listened to in front of the wall before.

It's just that the music played by the group of musicians is now clearer, and the sound they hear through the wall is more ethereal and long.

If it is replaced by crying, I am afraid that it will be the "ghost crying in the middle of the night" that haunts everyone in Qionghua Garden every night and is passed on mysteriously.

"What is the reason for this?" He Chaozhi was the first to react, breaking everyone's previous solemnity and sluggishness.

Qin Songen herself doesn't quite understand the physical principles in it, she can remember that she still talked about a sound wall in the Forbidden City in a set of "100,000 Whys" she watched when she was a child. It is said that as long as two people stand behind the east and west side halls, stand against the wall, and one person leans against the wall to the north to speak, the sound wave will be transmitted along the wall in the form of sound waves to the other end of a few hundred meters away, no matter how small the voice is, it can also make the other party hear clearly, and the sound is long, which can be called interesting, giving people a mysterious atmosphere of "heaven and man induction".

I can't remember the physics principles there, but because this thing is so fun, I wrote it down, and I thought that I would have the opportunity to go to the Forbidden City to find a friend to accompany her to find the echo wall to try it, but I didn't expect that it would not be possible to go to the Forbidden City in this life, but she still inadvertently discovered the "echo wall" here.

But at this moment, she had to come up with some reasoning to convince these people in front of her.

Therefore, Qin Songen had to recall her poor knowledge of physics, and pretended to be a bamboo in her chest to explain to everyone: "The wall here is made of grinding bricks and joints, smooth and flat, so the sound is trapped in this long wall and spreads, and it is not easy to disperse, but can be transmitted to all parts of Qionghua Garden with the help of this long wall. ”

Everyone didn't expect it to be such a simple reason, He Chaozhi looked at everyone in disbelief and asked, "You have never found out before?" ”

The people brought by Pei Ruchu looked at each other, which made Pei Ruchu's face seem to be a little unsightly, and the chamberlain who had spoken before defended himself: "This Qionghua Garden was only used to entertain the nobles who entered the palace to take a rest, and there was no one living in it. The place where Fang's girl cried late at night was remote, I didn't expect it to be so coincidental, the two compartments actually bumped into each other....." He said this, and suddenly exclaimed: "Could it be that it is really a coincidence?" ”

Qin Songen said at this time: "It's a coincidence, but it's not necessarily, you didn't find it, but someone discovered the strangeness here." ”
