Inside the wings.

Only Xia Tan'er was left wearing goggles and sitting alone at the table, facing the table full of chemical instruments.

She took out a roll of adhesive tape from her smart medical bag and carefully taped the letter and envelope with the tape.

But anything that has been filled with powder will definitely leave traces.

Even if it is invisible to the naked eye, it is possible to collect all the remaining powder with adhesive tape.

But in the time of half a cup of tea, the tape was covered with powder, and it was five centimeters long.

She cut a small piece of it and threw it into the distilled water, keeping the rest for the valley lord to distinguish later.

Xia Tan'er wore surgical gloves, held a beaker in one hand, and slowly stirred the glass rod in the other.

At this moment, she felt that she was back in the original laboratory, but looking at the antique furnishings around her, she suddenly lost her life.

When the powder on the tape gradually dissolves and the distilled water becomes cloudy, she dips a small amount of it into the test tube with a dropper and shakes it well.

Quietly waiting for the hour of a stick of incense.

However, the color of the liquid in the test tube has not changed in the slightest.

Xia Tan'er had already been able to conclude that this nitrite must have been placed elsewhere, and as for what the powder that was sprayed out of the envelope was, it was handed over to the valley lord to determine.

got the result, Xia Tan'er already knew it in her heart.

The onset of nitrite poisoning occurred within a few minutes to a few hours, and I heard from Laifu that Lu Yimo had a sudden attack not long after he came back from the palace, so the possibility of poisoning at home could be directly ruled out, and the rest was only left in the palace.

When the time comes, ask Lu Yimo carefully, and you will be able to roughly get the result.

However, I don't know where the person behind the scenes got the nitrite.

After thinking about this, the chemical instruments on the table were almost packed.

Xia Tan'er gently held the small piece of tape to open the door, but saw Xia Lingfang standing at the door of the room at some point.

Feng Muchi and the valley master greeted them at the same time, and Xia Lingfang also wanted to come up, but he took a step and retreated to his original position with a little hesitation.

Xia Tan'er glanced at Xia Lingdong, but in the next second, her attention was attracted by the other two.

"Tan'er."

"Tan girl, how is it going, can you find the medicine powder?"

"Found it."

Xia Tan'er slowly spread her hands in front of the two.

"Here."

"What is this?"

"It doesn't matter what it is, the powder is already stuck to it, you just have to check it, valley master."

The valley lord glanced at Xia Tan'er suspiciously, but still obediently picked up the rubber strip.

He reached out and dipped a little on his head, and his fingerprints were indeed stained with a little powder.

The valley lord rubbed his fingers and reached out to the tip of his nose to sniff.

The brow furrowed directly.

"Valley Lord, what's wrong, is it some kind of poison?"

Could it be that she didn't detect other poisons?

But Lu Yimo is indeed nitrite poisoning, which is not wrong, otherwise how can it be treated with vitamin C and methylene blue.

"It's not poison, it's flour."

"Flour?"

Xia Tan'er hurriedly took the strip back to the room, and the other three saw that the situation was not right, so they immediately chased after it.

Xia Tan'er took out iodine wine from the smart medical bag under the cover of the medicine box, sucked some with a dropper and dripped it, and after a while, the powder on the rubber strip turned from brown to blue, there is no doubt that iodine wine is good.

"It's indeed flour, it looks like the clue is broken again."

Flour is everywhere, and it's not a strange thing.

The only thing Xia Tan'er can be sure of is that the other party wants to blame her and put her to death.

Who exactly has such a hatred for her?

Early Ming Dynasty? Warm and affectionate? Or Tanglin Lo?

After thinking about it, the beginning of Ming Dynasty was the most likely, and I had a lot of precautions against him in my heart.

"There is no medicinal powder, and the old man doesn't know how to treat Mrs. Lu, you have to be prepared in your heart."

"Hmm."

Xia Tan'er pursed her lips, revealing a helpless look, she turned her eyes, and saw Xia Lingfang staring at her opposite.

There was a palpable longing in the other's eyes.

But Xia Tan'er didn't know how to call her, a brother who was only related by blood, for a while.

After thinking about it, I still detached myself.

"I wonder what clues Lord Xia can find out over there?"

Xia Lingfang was obviously stunned when he heard the words Lord Xia, and his eyes couldn't help but show a touch of loss, obviously for his own mother and his own sister to investigate the case together, but now the two of them are so unfamiliar.

It's just that he is guilty of everything.

"Princess Jin."

"I don't need to call Princess Jin anymore, from today I have reconciled with His Royal Highness the King of Jin, just call me by my name directly."

Xia Lingfang was a little surprised, when did his submissive sister grow into such a woman with her own opinions.

He seems to be missing out on a lot, a lot.

"Miss Tan'er, this official interrogated the little guy who delivered the letter, and he said that the letter was handed over to him by a woman and asked him to pass it on, but when he left, he looked at the woman with more thoughts, and if he could find the woman, he would definitely be able to recognize it."

"As for his details, the official has already found out that the people in the Lu Mansion are good, and there are no suspicions, and it is not a detailed work sent by outsiders."

"There's Lord Rausha."

"It's just an order, and I don't need to thank you, but this official has a request I don't know if Miss Tan'er can agree."

"What request?"

"I beg Miss Tan'er to allow this official to take a look at Mrs. Lu, this official is worried about Mrs. Lu's safety."

is obviously his own son, but like a stranger, he has to get permission from others to take a look at the safety of his own mother.

But he had no choice, if it wasn't for the Nine Emperor Uncle summoning him, he wouldn't even be able to enter the door of the Lu Mansion, let alone see Lu Yimo.

"It is natural for Lord Xia to care about his mother, but the safety of his mother is more important these days, if Lord Xia wants to see it, he should wait for his mother to wake up."

"Tan'er ......"

"It's late at night, Lord Xia should go back to the Prime Minister's Mansion earlier, and Tan'er won't leave Lord Xia."

"Come on, send Lord Xia out of the house."

"Yes, young lady."

Xia Tan'er didn't give Xia Lingfang the slightest face to refute and plead, and she was as cold as the people in the Prime Minister's Mansion turned her away.

However, she is not because of desperation, but because it is not appropriate for outsiders to know that Lu Yimo has woken up at the moment, for fear that she will startle the snake and let the bad guys be on guard, and it will be much more difficult to find out the culprit at that time.

It's also an excellent way to get the other person to take off their guards.

It's just that this scene fell in the eyes of Feng Muchi and the valley master, and I couldn't help but feel that Xia Tan'er was a little ruthless, especially Feng Muchi, who was already very attached to his mother, where did he see the scene of others falling apart.

"Tan'er, he is your own brother and Aunt Lu's biological son, are you going too far."

"That's right, it's just a glance, and there won't be a piece of meat."
