Until an extremely solemn voice sounded behind the two of them - "Ah Xu, what are you messing around again?" ”

Shen Xixu turned around when she heard the voice, the person who came was not someone else, but her biggest backer: Her Royal Highness the eldest princess.

Seeing this, Lu Xuan hurriedly leaned down, but he didn't dare to speak, for fear of being recognized as someone from Shen Xixu's side.

Shen Xixu couldn't help but panic when he thought of Lu Xuan, and hurriedly glanced at the eldest princess, signaling her not to break it.

The eldest princess is an understanding person, so naturally she will not expose her daughter's shortcomings in front of the palace people, and then stepped forward.

"It was the palace that ordered the county lord to bring people to pick up the medicine, and many people in the house have been infected with wind and cold recently, and the amount of medicine is a lot, and this little guy is also specially sent by the palace to assist the county lord."

The eldest princess's tone was extremely flat when she said this, but it sounded far more chilling than Shen Xixu's reprimand.

It's just that Lu Xuan is now thanks to help, and it's too late to breathe a sigh of relief, so where can he care about thinking about this?

The two palace people had already been defeated in front of Shen Xixu, and at this moment, with the blessing of the eldest princess, they didn't dare to stop them anymore, so they had to let the three of them in.

When he got to the house and saw that there was no one around, Lu Xuan hurriedly leaned over to the eldest princess: "The lower official and criminal department ordered Shi Luxuan to meet Her Royal Highness the eldest princess, Fang Cai did not intend to deceive, and asked Her Royal Highness for forgiveness." ”

"Oh? Are you Lu Xuan? The eldest princess asked casually.

Lu Xuan immediately nodded: "It's Xiaguan." ”

For a long time, Lu Xuan's name has always existed in the ears of the eldest princess, but today is the first time I have seen it.

I thought that the person who could please Gu Huanli must be quite capable, but I didn't expect that when I saw it today, it was such a white little life, but people couldn't be disgusted no matter what.

No wonder even Shen Xixu praised Lu Xuan, so many conditions were accumulated, and the eldest princess's first impression of Lu Xuan was still good.

After being silent for a moment, the eldest princess took her eyes off Lu Xuan and turned to look at Shen Xixu with a serious face: "Didn't you go with your imperial uncle to investigate the case?" How did you get here? "Still with Lu Xuan.

In the second half of the sentence, the eldest princess didn't ask, but just glanced in Lu Xuan's direction unconsciously.

Shen Xixu noticed his mother's suspicious gaze, and hurriedly opened his mouth to explain to Lu Xuan: "I am indeed handling the case for Uncle Huang, and Lord Lu is here because of this. ”

"Oh? What does the case for your imperial uncle have to do with this Imperial Medicine Pavilion? "The eldest princess doesn't know why, she just thinks that Shen Xixu is playing a child's character and pulling Lu Xuan to mess around.

This time, she wronged Shen Xixu, and she immediately refuted: "The Imperial Medicine Pavilion lost quinine a few months ago, and His Majesty actually suspected that it was the emperor's uncle, and the emperor's uncle was inconvenient to come forward in person, so he had to ask Lord Lu to do it for him." ”

When the eldest princess heard this, she immediately looked at Lu Xuan: "Can this matter be taken seriously?" ”

Lu Xuan nodded: "It's true, His Highness ordered the officials to find out the truth before the West Factory, so as not to be framed by villains." ”

Seeing that what Lu Xuan did was indeed to protect Gu Huanli, the eldest princess nodded: "Since that's the case, let's investigate carefully." ”

After speaking, the eldest princess immediately sat down on the side and let Lu Xuan show her skills in the Imperial Medicine Pavilion.

With the permission of the eldest princess, Lu Xuan seized the time to investigate, and Shen Xixu was unwilling to be idle, so he hurriedly followed and watched.

Time was pressing, and Lu Xuan didn't dare to delay for too long to arouse suspicion, so he could only walk around the Imperial Medicine Pavilion and use his extraordinary memory to record the appearances of all places.

Shaoqing, before the wooden bench under the eldest princess could sit hot, Lu Xuan had already walked over to her: "Today, there is Her Royal Highness Princess Lao." ”

The eldest princess didn't care about this matter, but asked Lu Xuan in surprise: "You found out in such a short time?" ”

Lu Xuan shook his head: "No, Xia Guan just browsed everywhere and memorized it in his mind in case of future needs." ”

"In such a hurry, if you forget, won't this trip be in vain? You have seen how difficult it is to come in, is it possible that you are still looking forward to a second chance? The eldest princess questioned Lu Xuan.

Lu Xuan replied indifferently: "The lower official's memory is not bad, it shouldn't be a problem to record what he sees in front of him for a few days, and the guards were already suspicious when he entered the door, and the lower official didn't want to expose his intentions." ”

Shen Xixu understood this, and seeing that the eldest princess had been interrogating Lu Xuan, she immediately stepped forward to explain:

"Mother, Uncle Huang said to keep a low profile, if we stay here for too long, it will indeed arouse suspicion, Lord Lu's move is not only for Uncle Huang's consideration, but also does not want to harm Mother."

Hearing this, the eldest princess couldn't help but glance at Shen Xixu, she really didn't know when her daughter learned to turn her elbow towards an outsider who met in Pingshui.

However, Lu Xuan was indeed loyal to Gu Huanli, and everything he did was out of his consideration, and the eldest princess temporarily put her mind at ease.

She then got up: "In that case, let's go." ”

Lu Xuan followed the two nobles and bowed his head and went out, and the three of them walked all the way until they stopped outside the palace.

At that time, Qin Wei had been waiting outside for a long time, and when he saw Shen Xixu hurriedly catching up, he saw that the eldest princess was also among them, and hurriedly saluted: "Your Royal Highness the eldest princess has seen your majesty." ”

The eldest princess recognized Qin Xiao, and as soon as she saw him appear, she instantly thought of Gu Huanli, and hurriedly looked around unconsciously, but she didn't see that majestic figure.

"What about the Fierce King?" The eldest princess searched for it without success, and then asked Qin Xiao.

Only then did Qin Xiao realize that he had not yet explained his intentions, and hurriedly responded: "Your Highness did not come, and the lower official was ordered by His Highness to protect the county lord." ”

The eldest princess was originally worried that Shen Xixu would be in danger if she followed Gu Huanli, but seeing that he had already stationed his right-hand man beside her, it seemed that there was nothing to worry about.

After thinking for a moment, thinking of what Lu Xuan had just said, wanting to come to Qin Wei to stay here must also be avoiding people's eyes.

Only then did the eldest princess speak: "There are many people here, if you have important things to do, leave as soon as possible." ”

Hearing this, the three of them hurriedly bid farewell to the eldest princess, and then returned to the Lu Mansion together.

At the same time, Rong Liao also had a new idea to discuss with Lu Xuan, and it happened that she returned to the mansion.

Rong Li hurriedly greeted him: "Ah Xuan, I have a new idea." ”

Lu Xuan smiled when she heard this: "I am also making some discoveries." She said as she walked over to Rong Li.

Looking at the appearance of such a tacit understanding between these two people, it really made Shen Xixu puzzled.

"What did they find?" Shen Xixu turned his head to look at Qin Xiao, but he shrugged helplessly and said nothing.

She had no choice but to come in the direction of Lu Xuan and Rong Li, and sat quietly on the side to listen.

Rong Liao had a way of thinking, but seeing that Lu Xuan had just returned from the scene of the crime, what he said must be more reasonable, so he simply listened to her first.

Lu Xuan immediately spoke: "I just found some strange powder in the corner of the Imperial Medicine Pavilion, and the smell is very close to quinine. ”

As she spoke, Lu Xuan took out a square towel from her arms, which was filled with the same thing she had brought back from the Imperial Medicine Pavilion.

Rong Liao took the scarf and sniffed it, then nodded: "It's indeed quinine." ”

"But I've heard that all the quinine in the Imperial Medicine Pavilion has been stolen!" Shen Xixu suddenly interjected.

Lu Xuan suddenly had doubts in his heart: "If quinine was stolen a few months ago, why did these powders survive to this day?" ”

Speaking of this, Shen Xixu also felt strange: "Yes, the Imperial Medicine Pavilion will be cleaned every three days, and the palace people who clean with such an obvious powder should not ignore it." ”

These words instantly made Lu Xuan have a bold guess in his heart: "Could it be that quinine was not lost a few months ago at all, but within these three days?" ”

"Three days? Who can get all the quinine out of the palace in three days without knowing it? Shen Xixu was puzzled.

Rong Liao also felt that this kind of possibility was very small, and casually put forward another conjecture: "Could it be that these quinines were not lost all at once?" ”

This Lu Xuan hadn't thought about it before, what Gu Huanli told her at the beginning was that a large number of quinine were lost, and she actually took the opportunity to associate them with the same batch.

Now that he was allowed to lie like this, Lu Xuan remembered another strange thing he had just seen in the Imperial Medicine Pavilion-

"Speaking of which, I just saw a few white scratches on the side of the door frame of the small door in the Imperial Medicine Pavilion, which seem to be wax marks, look at the shape of the wax traces, it seems to be caused by scratching when the box was carried out."

"But how can there be wax in the Imperial Medicine Pavilion?" Shen Xixu was puzzled.

Rong Liao then remembered: "I looked through the previous classics and found that when the plague broke out a few years ago, the imperial court also transported a large number of quinine southward along the waterway. ”

"So those wax stains at the entrance of the Imperial Medicine Pavilion will also be used to prevent moisture?" Lu Xuan guessed.

Shen Xixu still felt that it was not necessarily: "Some of the quinine in the palace was also transported from the south of the Yangtze River by water, maybe the wax traces were scraped into the corner of the wall when they were transported into the Imperial Medicine Pavilion?" ”

Lu Xuan shook his head: "No, the scratches are heavy and thick in the direction of the house, and shallow and few in the direction of the outside of the house, which must be caused by the transportation from the inside to the outside." ”

This inference simply made Shen Xixu admire Lu Xuan.

In such a short period of time, it was not easy for Lu Xuan to discover quinine powder and wax traces, but she didn't expect that she could even remember the shape of the wax stains clearly, and she also knew how to use this as the basis for inferring entry and exit, which was simply admirable.

However, there is an easier reason to overturn Shen Xixu's thoughts.

Although Rong Li had never been to the Imperial Medicine Pavilion, he still mentioned: "Besides, the palace can only enter through the main entrance to transport medicines, so why does it leave a wax mark at the side door?" ”

Such clues were connected, and Lu Xuan immediately closed his eyes and conceived the appearance of the Imperial Medicine Pavilion in his memory.

Quinine was stored on an empty medicine shelf, removed and packed, accidentally spilling powder in the corner of the wall on the way, and carrying the wax-coated wooden box out of the side door......

"The side door of the Imperial Medicine Pavilion is connected to the Mirror Lake of the Imperial Garden, and the wooden box is transported out of the side door, and it is covered with wax traces, is it not the water of the dock that the wax traces prevent, but the water of the Mirror Lake?"
