Bai Jingyin had already returned to the palace, and she was lazily half-lying on the bed, playing with her sleeves a little boringly.

The design of the ancients' clothes is really ingenious, although it is a little inconvenient to move, but the design of the sleeve pockets really makes her, a special soldier, secretly surprised.

The clothes are gorgeous, and there are various hidden bag designs, which are more convenient to put things, but the clothes are too long, and the skirts are all mopping, which really seriously affects her movements.

On the contrary, Commander Zhang's guard uniform was much better, but she didn't know what this ancient military uniform looked like, and she suddenly wanted to see it.

Just thinking about it, Bai Jingyin heard the sound of opening and closing the door outside, and knew that Chengying had returned.

She got up in some haste, and felt that it was not good for her to be so excited, and sat down on the bed with some chagrin.

After a while, Chengying's voice sounded.

"Miss, the slave is back."

Chengying's voice was very low, as if it was very close to the door, as if he was afraid of being heard by others.

Bai Jingyin knew what she was afraid of, she also had a bunch of questions to ask, and hurriedly responded: "Come in!" ”

There was a little haste in this voice, Chengying looked around, and hurriedly opened the door and walked in.

As soon as I entered, I saw Bai Jingyin dressed in black, sitting on the edge of the bed with an expectant face, looking at her.

Chengying smiled helplessly, and immediately guessed what the young lady was doing at night, she saluted, and before she could stand up straight, she heard Bai Jingyin's anxious voice sound.

"Tell me, what kind of poison is that?!"

Chengying straightened up, sighed secretly, and said with a little grievance: "It turns out that Miss has long known what Commander Zhang asked the slave to do, and Miss is so good that she doesn't tell Chengying ......"

What kind of maid is the maid next to her Bai Jingyin knows in her heart that Chengying is a smart person, and she is transparent at all, and she doesn't want to be brutal, isn't this to make acting more realistic!

She scratched her head and said a little apologetically: "Chengying don't blame, your young lady is not trying to prevent Commander Zhang from seeing the clues!" ”

If she directly told Chengying the reason for the incident, Commander Zhang was so smart, she couldn't guarantee that Chengying would reveal any flaws, and when it came to acting, she still felt that she was a little more exquisite!

Well! That's it!

Bai Jingyin raised her eyebrows confidently, saw Chengying muttering, and said, "Miss has to do a full set of plays next time, what if the commander comes back with the slave?" ”

"Got it, got it! Hey. Bai Jingyin scratched her head, isn't she confident!

"Don't digress!" Bai Jingyin hurriedly said: "Chengying, tell me quickly, is that poison or not, and what kind of poison is it?" ”

Chengying looked at her young lady helplessly and said, "Miss, that's colorless." ”

"No dispersion?" Just listening to the name, Bai Jingyin knew that it was indeed colorless, but this kind of thing, she had never heard of it as a modern person, and this ingredient was ......

"Yes." Chengying nodded, and continued: "That colorless dispersion is usually nothing, and the ingredients in it are relatively simple, if you want to poison people, you have to let people take it." ”

"Take?!" Bai Jingyin exclaimed, can you still take that powder if it falls to the ground?!

"Miss, don't worry, after Rong Nuwen finished speaking, in addition to taking it, no dispersion requires a medicine to be effective." Speaking of this, Chengying suddenly leaned closer and said, "That medicine is safflower ......."

"Miss, safflower has the effect of breaking down stasis and removing swelling, and it has the function of invigorating blood and removing stasis, so this flavor medicine is indispensable."

After speaking, Bai Jingyin fell into deep thought, she heard a few days ago that Concubine Yu Guifei had been depressed recently, and she was often prone to insomnia and bad dreams.

"Chengying, people with insomnia, are the drugs they take mixed with safflower?"

Chengying thought for a while, nodded and said: "Yes, people with insomnia can take ginseng 100-year-old wine, that is, medicinal wine brewed with red ginseng, rehmannia rehmannia, jade bamboo, shou wu and other medicines. ”

"Oh." Bai Jingyin nodded, then this safflower is explained, but how did the non-dispersion make Yu Guifei take it?

Bai Jingyin held her chin with her hand, and thought for a long time, Chengying stood aside obediently, and the young lady didn't speak, and she didn't speak.

After pondering for a long time, a light suddenly flashed in Bai Jingyin's mind.

When she went to peek at the picture of the spring palace that day, she passed by the medicinal powder, and she seemed to remember that a palace maid spilled a plate of melon seeds on the ground.

And the place where it was spilled happened to be the place where the powder was scattered.

That plate of melon seeds, she remembered as if they appeared on the table beside her when Concubine Yu and His Majesty were playing chess!

Thinking of this, she hurriedly asked again, "Chengying, what will happen to this powder man?" ”

Chengying didn't expect Bai Jingyin to ask like this, and hurriedly said: "Miss, the reason why it is called non-dispersion is precisely because it has no effect, only safflower is the medicine induce, and taking safflower within an hour after taking it will cause poisoning!" ”

"Then why did you cover your mouth and nose when you first explored?"

Miss really went to investigate secretly, Chengying was helpless, and said, "Miss, covering your mouth and nose before exploring medicine is a safe strategy!" ”

"Oh." Bai Jingyin nodded, she had forgotten that those researchers were also fully prepared when they went to the research room in the past.

Melon seeds......

His Majesty came in person that day, presumably Concubine Yu was also very excited, in order to please Your Majesty, Concubine Yu naturally did it herself, she must have come personally to eat melon seeds, and those thieves also guessed that Concubine Yu would do this, so they thought of this poisonous plan!

After this series of events, Bai Jingyin couldn't help but sigh, the person behind him was so thoughtful, disciplined, and stripped of the threads, even she almost didn't see it, let alone the scheming Yu Guifei.

It's just that palace maid......

Bai Jingyin frowned, thinking about it carefully, and the picture of that day appeared in front of him.

"Qiuqin, why did you accidentally spill the melon seeds so much!"

"Pick it up!"

Qiuqin ...... That palace maid's name is Qiuqin?!

Why did she feel that this Qiuqin name was a little familiar?

Bai Jingyin sank his eyes and asked, "Chengying, do you know a palace maid named Qiuqin?" ”

"Qiuqin?" Chengying's eyes widened, "Miss, didn't that serve you before?!" Have you forgotten? Previously, you were beaten into the cold palace, and all the palace maids below were scattered, leaving only Chengying alone! ”

Served her?!

Finished!

Bai Jingyin's heart was shocked, and he changed his hippie smiling face from the past, and replaced it with a sharp one.

What a plan!

I really didn't expect that the people in the harem were so scheming, and when she turned her head, she found out on her own head?!

She raised her head slightly, looking at the sky, at this moment, Commander Zhang should have already made it clear to him, and Concubine Yu was about to leave.

If it weren't for her tossing tonight, Concubine Yu would have died of excessive blood loss, and when she was investigated, it was poisoned by her Bai Jingyin's palace maid.

What a killing two birds with one stone!
