An Sheng checked this for a long time.

When she came out of the palace, it was only more than half of the time, and after she returned to the Protector's Mansion, it was only half of the time, but she checked from the middle of the time to the middle of the time, but she has not made any progress, even lunch and dinner, all of which were used casually in the room.

Lin knew that she was busy, and he didn't ask others to disturb her.

As a result, more than half of the day, An Sheng checked less than half of the medical classics, and most of them still haven't been checked.

Lu Zheng saw that An Sheng's eyes were red, and he was really distressed, and when he arrived, he didn't allow her to check it no matter what, and urged her to rest quickly.

An Sheng couldn't resist Lu Zheng, and he was indeed a little tired, so he put down the book first, and prepared to get up tomorrow morning to continue checking.

After hurriedly washing, Lu Zheng urged An Sheng to go to bed to rest.

An Sheng saw that the hour was indeed not early, and Lu Zheng would still go to court tomorrow, if he didn't sleep, Lu Zheng would definitely not sleep well, so he went to bed with Lu Zheng to rest.

However, after lying down, An Sheng still couldn't sleep, always thinking about which book he had seen similar records, thinking about whether he could scavenge useful information from his long memory, so although he lay down, he still didn't feel much sleep.

Because he was worried that Lu Zheng would find out that he hadn't slept, An Sheng didn't dare to move, so he just lay straight and straight, half-squinting his eyes and recalling.

Who knew that he was thinking about it, but he was suddenly fished into his arms by Lu Zheng, and then, a big palm was attached to his eyes: "Okay, go to sleep, be obedient." ”

The tone of this disobedient child really made An Sheng a little funny and helpless.

However, he obediently forced himself to sleep.

I thought I wouldn't be able to sleep, but I kept my eyes closed, and finally fell asleep in a daze.

It wasn't until An Sheng's breathing stabilized that Lu Zheng reopened his eyes, looked at An Sheng through the faint candle flame, and smoothed the wrinkles between her eyebrows before carefully hugging the person and falling asleep.

......

Soon, it was midnight.

At this time, in the dead of night, it should have been a good dream, however, An Sheng suddenly opened his eyes, and a pair of eyes looked at the top of the tent with bright eyes, and he was no longer sleepy.

She remembered!

She knew in which book she had seen something like this!

I was thinking about whether to secretly get out of bed and flip through the book, but I didn't want Lu Zheng to wake up.

And when Lu Zheng woke up, he still came to see himself first.

"What's wrong, but you're having nightmares?" Lu Zheng propped up his upper body and looked at An Sheng a little nervously.

Lu Zheng has always slept lightly, so An Sheng noticed it when he moved a little.

However, he obviously misunderstood, thinking that An Sheng woke up at this time because he was scared by nightmares.

An Sheng was entangled for a while, but still told Lu Zheng the truth.

She turned over, turned to Lu Zheng, and then said to him, "I remember which book that book is." ”

Lu Zheng woke up in the middle of the night, still a little confused, and hummed a little confused before he reacted, "You mean, do you know which book to look up?" ”

"Yes, exactly."

Lu Zheng couldn't help but feel a little helpless when he saw An Sheng's eyes shining in the night, but he still said: "You tell me which one it is, and I'll find it for you." ”

So saying, he got up and got out of bed.

An Sheng's heart warmed, and he told Lu Zheng the title of the book, Lu Zheng nodded, and said, "Sit down and wait for me." ”

With that, the man turned and walked away.

An Sheng hugged the quilt and sat on the bed honestly waiting for Lu Zheng to come back.

......

About a quarter of an hour later, Lu Zheng came back with a book in one hand and a lamp and candle in the other.

Back in front of the bed, Lu Zheng handed the book to An Sheng and asked, "But this?" ”

An Sheng took it and looked at it, nodded hurriedly and said yes, and then smiled sweetly at Lu Zheng, "Husband, you are so good." ”

Lu Zheng was stunned by An Sheng's sudden title, and then his ears couldn't help but turn red, and he hurriedly covered his mouth with his fists, coughed lightly, and then said in a rough voice: "Okay, let's take a look." ”

After that, he put the candlestick closer to make it easier for An Sheng to check.

An Sheng had already seen that Lu Zheng was embarrassed, but he didn't say anything, only pursed his lips and smiled secretly, and went to look through the books in his hand.

An Sheng asked Lu Zheng to bring the book called "Broad Group of Plants and Trees", which describes the names of many flowers and plants, the origin of the extremely characteristic and so on, is one of the many books in Master Puyun's collection, An Sheng has read some of them in his previous life, but he has not finished reading them, so he remembers it not so clearly.

I don't know how many things have a different fragrance, but the fragrance of all things in the world is not completely the same, and there are always a little differences between different things, but not everyone can smell it.

An Sheng has carefully studied this kind of knowledge because of the development of rouge gouache and other substances, and she is sensitive to fragrance, so she smells a strange fragrance from Rong Guifei.

It is a taste that is very similar to the aroma of rouge gouache.

The queen didn't smell it, she only thought that Concubine Rong was rubbing the incense powder and balm, but she didn't know that under the fragrance of the incense powder and balm, there were other smells.

And if it was usual, An Sheng might not pay attention to this subtle difference, but she was invited to the palace by the queen, but there was a prerequisite.

That is, Rong Guifei suddenly returned to favor, and the degree of favor was not as good as before, and before and after, the Wang family sent Rong Guifei a secret medicine, because these prerequisites were added together, An Sheng would notice the unusual aroma on Rong Guifei's body.

In fact, the fragrance of Rong Guifei is not too special, it is tansy, this thing was introduced to Middle-earth from overseas in the previous dynasty, also known as rosemary overseas, is a very special aroma of plants, can be used as fragrant dew, can also be used in dishes, but because this dynasty does not use much, few people know this thing anymore.

The most important thing is that this thing has a special effect, its aroma can be aphrodisiac, but what the effect is, An Sheng has not tried it personally, but he doesn't know.

However, if you add ylang-ylang, then this effect should not be underestimated.

Rong Guifei suddenly returned to favor, and the favor was unprecedented, to say that there is no problem in this, it is indeed unlikely.

And these two aromas are probably the main reason for her resurgence.

Since ancient times, the concubines have competed for favor, and the means used are nothing more than those, in order to win the emperor's heart, so it is not surprising that Concubine Rong will use this kind of thing that contains aphrodisiac effects.

It's just that how she uses it, An Sheng is not sure.

I didn't see the shadows of tansy and ylang-ylang flowers in Zhaoyang Palace that day, I think most of them should be used in fragrance and incense powder, and even more so, it was added to Wang Jiajin's secret medicine at all, and it is unknown.

It's just that no matter which one it is, you have to tell the queen and the crown prince the news quickly.

How to do this matter depends on the queen's intentions, if Concubine Rong really uses such means to compete for favor, the queen has the right to dispose of her.
