Inside the elders' room.

After the needle was applied, Mr. Lu's whole body seemed to be scooped up in water, the bedding under his body was already soaked, and the pajamas at home were completely wet with sweat.

Su Xiruo took off the last silver needle and was about to wipe his sweat.

Suddenly, a slender hand stretched out from the side.

The owner of the hand held a silk handkerchief, and wiped the sweat from her forehead and neck with seriousness and seriousness on her handsome face.

"Drink something."

After Lu Tingchuan wiped her sweat, he naturally took a cup of nutritious juice and handed it to her.

Su Xiruo pursed her lips, and when she took the cup, her heart was warm.

There was also a surge of heat in her eyes, and she was forced to suppress it.

"Ruoruo, how is my old man now?"

Mrs. Lu asked with a concerned face.

She knew that the traditional Chinese medicine who could use acupuncture and moxibustion had always had to maintain full attention when performing acupuncture, so when Su Xiruo was prick his wife's needle, the old lady even subconsciously slowed down her breathing, for fear of disturbing her.

"It's just the first time."

Su Xiruo looked at the extremely weak old man and recruited a servant to change his clothes.

"According to the time, the poison in the old man should have been more than ten years." Su Xiruo said, "If you want to completely unravel it, you have to go through at least six injections, so I still have to keep drinking the recipe I gave before, which can enhance the old man's physique." ”

Old Mrs. Lu suddenly smiled, "This is definitely no problem, the remaining few times will trouble you Ruoruo." ”

"Don't worry, Grandma Lu, I took Mr. Lu's money, and I will definitely let the old man ...... Grandpa Lu is back to normal. ”

Su Xiruo said confidently.

Seeing this, the old lady breathed a sigh of relief.

The old couple used to be a war couple, and they went through life and death all the way, and their feelings for each other were also very strong.

On weekdays, I am afraid that he will suddenly leave one day.

Now that she finally saw hope, the old lady burst into tears of excitement.

Old man Lu also felt that after the injection, his body's skills were slowly recovering, watching his wife cry, he raised his hand to help wipe it, and said with a gentle smile, "I'm so old, and I love to cry so much, and I'm not afraid of juniors watching jokes." ”

The maid had already changed the old man's new bedding and clothes.

From the strength of his words, I could feel that the situation was much better than before.

"Just laugh, and I'm not an outsider."

Mrs. Lu said in a very good mood.

Su Xiruo and Lu Tingchuan stood aside, silently looking at the couple who were still sprinkling dog food.

Knock Knock –

Suddenly, there was a knock on the door.

Another servant immediately went over and opened the door.

I saw a middle-aged maid coming over with a medicine bowl, "Old lady, sir, the old man's medicine has been boiled." ”

"Quick, bring it." Old Lady Lu hurriedly beckoned, "I'll feed this old man medicine." ”

Old Man Lu suddenly had a bitter and hateful face.

Lu Tingchuan explained with a light smile, "Grandpa doesn't like to drink Chinese medicine very much, and he has to be watched by grandma every time to drink it." ”

Su Xiruo was a little envious of such feelings, she said, "Grandpa Lu will just drink it for another month, and after the next acupuncture, I can make some pills, which is also more convenient." ”

Old Man Lu suddenly asked, "Why can't you just take the pill now?" ”

"Grandpa Lu's current body, drinking the freshly boiled medicine will absorb it faster." Su Xiruo explained.

This is, the middle-aged maid has passed by her with a medicine bowl.

The strong smell of medicine came to his nose, and Su Xiruo subconsciously frowned and looked at the bowl of soup medicine.

Old Madam Lu was about to reach out and take it, when she heard her crisp voice sound: "Wait." ”

Su Xiruo stepped forward and directly picked up the medicine bowl and put it under his nose to sniff lightly.

Then her eyes sank, and she looked at the middle-aged maid coldly and asked, "This medicine, are you sure it was taken according to the prescription I gave?" ”

The middle-aged maid didn't know why, "Of course, it was the medicine that Steward Fang went to the pharmacy to grab personally." ”

"It doesn't taste right."

Su Xiruo sniffed carefully several times before he said with certainty.

"What's wrong?"

The three members of the Lu family asked at the same time.

Lu Tingchuan squinted slightly, and guessed something in his heart.

"This medicine doesn't taste right." Su Xiruo said, "There is a medicinal herb added to it that I haven't written about, a bit like ...... Blue drenching grass? ”

Su Xiruo's pupils shrank.

"That's right, it's blue raingrass."

Lu Tingchuan knew that she had saved a group of children who had been infected with blue drenching mushroom toxin in the imperial capital before.

The medicinal properties of the blue drenching herb can solve the poison of the blue drenching mushroom.

But he remembered that the pharmacy at home didn't have enough blue drench.

"Blue drenching grass can detoxify the poison of blue drenching mushrooms, but when boiled with a few flavors of medicine in the prescription I prescribed, it will produce the same toxin as blue drenching mushrooms." Su Xiruo looked at Lu Tingchuan with a solemn expression, "Mr. Lu, the people who do their hands and feet in the decoction should not use fresh blue grass, but the powder that is ground after drying it. ”

Old Mrs. Lu also heard what she meant, her face turned pale, and she asked with a heart, "Ruoruo, what do you mean by this?" ”

"It seems that Mr. Lu's home is not very quiet."

Although Su Xiruo didn't say it explicitly, he had already told the Lu family's ancestors and grandchildren the answer.

Old Man Lu laughed angrily, "Okay, good! You dare to put your hand to me! Even Lao Tzu came to Nanyun City to recuperate, but he was watching under the noses of others! ”

Old Madam Lu was also angry, and immediately asked the maids in the house to control the middle-aged maid first, and then immediately called Butler Fang and asked him to gather all the servants who took care of the old man and herself.

The old lady who once killed the enemy on the battlefield and stained her blood was kind to Cixi on weekdays, and she was called the national grandmother because of her good personality.

But once someone touches her bottom line, the Iron Lady, who once rushed into the enemy camp very strongly, is not so easy to talk to!

This bowl of decoction should be kept as evidence, and it is naturally impossible for the old man to take it again.

Lu Tingchuan instructed Steward Fang to grab the medicine and boil it again, and personally sent it to the old man, before he looked at these servants who were in a hurry.

The Lu family is such an ancient family, and the servants used are also selected from the families that have served the Lu family for generations.

Lu Tingchuan didn't think that this incident would be the hand of someone in his house.

Then the most suspicious is one of the people brought by the old man and the old lady from the imperial capital.

"Master, a total of 18 servants, all of them are already here."

Steward Fang was also afraid for a while when he learned that someone had poisoned the decoction.

If something really happened to the old man, he, the person who went to grab the medicine in person, would be afraid that he would not be able to escape the blame!

But what disgusted him even more.

Among these servants who took the salary given by their own father, there were still things to eat inside and out.

He had to find them out himself.

"Hmm."

Lu Tingchuan's cold eyes swept over the eighteen servants one by one, with a strong sense of oppression.

The servants didn't know exactly when it happened, and they were stared at like this, and they only felt creepy, and they subconsciously became nervous.

"Master, what did you call us here for? Is it something we are doing badly? ”

"I have served the old man for more than 30 years, how can I give the old man a medicine in his decoction! Don't wronged good people! ”

"I've never touched that medicine bowl, I've always been in your old lady's room, and I don't know anything."

Steward Fang briefly stated the matter.

Knowing that the decoction that the old man in the family was going to take was actually poisoned, these servants immediately explained it in a gossip.

Among these people, either they have never even approached a meter away from the decoction, or they have been certified by others from beginning to end.

Under Steward Fang's interrogation, none of the eighteen servants had time to commit the crime alone.

Even the middle-aged maid who was in charge of delivering the decoction had been accompanied by another maid all the way, and had never been in contact with the decoction alone at all.

Lu Tingchuan looked at the reactions of these servants lightly.

"Say it again, Steward Fang, and see if what they say is the same as the first testimony."

"Yes."

Steward Fang asked again.

It turned out that nothing was found.

Lu Tingchuan squinted his eyes and let these servants stretch out their hands and sweep their eyes one by one.

Suddenly, he turned his head and asked Su Xiruo, "You said that the medicine in this decoction is the powder of the blue drenching grass that has been dried and ground into it, right?" ”

"Yes."

Su Xiruo was only responsible for curing the disease, but he didn't plan to get involved in such a thing as a wealthy house.

She was also very curious about what method Lu Tingchuan would use to find out the person who poisoned her.

"Is the powder of the blue drenching herb white?" Lu Tingchuan asked again.

"It's not." Su Xiruo shook his head, "It's gray-brown." ”

Lu Tingchuan nodded, swept the hands and nails of these servants one by one, and suddenly raised his hand to point directly at the maid who was said to have been by the middle-aged maid's side and came to deliver the medicine with her, "You are the one who gave the medicine, right?" ”

The maid is about forty years old, and everyone calls her Aunt Zhong on weekdays, and she is the person who serves the old lady.

It is also the most trusted one of the old lady.

Aunt Zhong was suddenly identified by Lu Tingchuan, and immediately turned pale with fright, and hurriedly explained, "Master, I haven't touched that soup bowl from beginning to end, Ah Xiang can testify for me." ”

Ah Xiang was the middle-aged maid who brought it.

Ah Xiang hurriedly nodded, "Yes, the carillon has never touched the soup bowl, and even when the medicine is boiling, he stands at the door and talks to me, master, are you mistaken." ”

Old Lady Lu also frowned, "Chuanbao, Xiaoqin, this child has been raised by my side since she was a child, how could she attack your grandfather?" ”

"There's no going wrong." The corners of Lu Tingchuan's lips curled up with a hint of mockery, and his dark eyes stared at the carillon and said, "You said that you never touched the soup bowl, so what did you do after she brought the bowl to the door?" ”

Zhongqin pressed an uneasy mood and said, "I...... I went to the bathroom. ”

"Looks like you've flushed the powder down the toilet, right?" Lu Tingchuan looked at her sarcastically and said, "Do you think that in this way, you can die without proof?" ”
