The color of the tea soup was originally green with a slight yellow, but this note was soaked in the tea soup, but it suddenly came out blue.

At first, it was just light blue, but the color quickly turned dark, until finally it changed to indigo!

He Xiaokite took out the note and shook it towards everyone: "A few years ago, I rescued a horseshoe crab demon on the beach. It gave me a few drops of blood to save my life, and I made these test strips. After a pause, his face smug said, "Do you know the effect of horseshoe crab blood?"

Although that thing is rare, it is not unique, and one medical officer can't get used to seeing her tail going to the sky, and snorts slightly: "Who here doesn't know that it is a good medicine for testing poison?"

"The note is dark blue, which means that the tea is too cold. He Xiaokite added, "When the horseshoe crab demon stays in the deep sea, its blood is blue. ”

Lord Luo didn't have the heart to care about the small knowledge of the horseshoe crab demon, so he went straight to the cup, and sure enough, he was cold!, "What's going on?"

This kind of cold seems to be able to invade along the fingers and arms, and if you hold it for more than a dozen breaths, the chill will reach the bottom of your heart.

Strangely, he had touched this cup when he arrived earlier, and the temperature was normal. And not only him, but all the medical officers present had examined it, and they didn't notice anything strange.

But now the cup is frozen like ice from a cold cellar, and there is no frost on the surface. The medical officers had already examined it and confirmed that there was nothing wrong with it, and now no one touched it again, and it had missed such an abnormality.

Obviously placed next to the fire, why is it getting colder and colder?

He looked at the cup, which was a normal clay cup. I don't know how long it took the villagers who originally lived here, and the color was a little dull.

"If the cup is fine, the tea is fine—" He Xiaoyuan turned his head and asked the maid, "Hmm, the tea is fine, right?"

The maid hurriedly shook her head, and a medical officer also said: "I have just specially tested the tea, which is non-toxic and harmless." ”

He Xiaoyuan continued: "-Tea is fine, then there is a problem with the water." ”

The eldest of the medical officers had already taken the pottery cup in Lord Luo's hand and examined it repeatedly, and then his face was solemn: "We have to re-examine it." ”

They are all court medical officers, and their medical skills are exquisite, and now that they have found a breakthrough, they don't need a few doctors to intervene anymore.

Then there is a new round of diagnosis, discussion, and the water in the cup is also taken care of.

After more than a quarter of an hour, the head of the medical officer turned around and respectfully handed over the new prescription to Lord Luo: "My lord, thanks to this girl's new discovery, the prescription and the dosage have been adjusted, but if the dosage is doubled, it will never be feasible!" Speaking of this, he glanced at He Xiaoyuan, who "cut" and rolled his eyes, "That's not the cause I found out?"

She was telling the truth, but none of the doctors gave her a good look.

After all, this is just a doctor who doesn't go into the stream.

Lord Luo nodded. Now that the medical officers were confident, his heart was also relieved: "The cause is the water for making tea?"

"Yes. "The water in the well is cold to the bone, and the effect is slow, so we didn't notice anything unusual when we took this cup." However, it is not only used to make tea, but also used to rub the body to cool down, so that the cold poison invades the patient's body again and again, which is also the reason why we have repeatedly used medicine to remove it. ”

Lord Luo waved his hand to the other medical officers: "Okay, let's treat it quickly." Then he turned to the medical officer in charge and asked, "How did this cold poison come about?"

"In the cold winter, the deep mountains and the bottom are cool. It is not surprising that the well water gushing out from there also brings out the cold. The doctor explained, "I wonder if anyone else has drunk the water from that well tonight, but there are cases of poisoning or high fever?"

This is a matter of asking a few of the captains, after all, the servants and servants will come to them if they are sick.

Several of the doctors on board shook their heads. It was a peaceful night for them, and they slept soundly before the guards came to the door.

"That is the patient's physical problem, so he will be taken advantage of by the cold poison. The medical officer whispered," Liao ...... This person's body is excessively depleted, dragging on day by day, and the number of symptoms is complicated in the morning and evening, which is the internal cause of the disease. Cold poison is just an introduction. He wanted to say that the patient could no longer stand the fatigue of traveling, but remembering the current situation, he swallowed this sentence back into his stomach.

Lord Luo snorted: "Try your best to heal, and get through the next few days first." He stood up and strode out.

Who would dare to stop him?

Yan Saburo muttered: "Jinzi, say okay......"

The voice was not loud or small, vague, but it was just enough for Lord Luo to hear.

Lord Luo paused, and ordered to the left and right: "Reward!"

Soon someone sent a hundred taels of gold. He Xiaoyuan smiled and took it, and the other two doctors in the team stared at the golden ticket in her hand and swallowed their saliva.

One hundred taels of gold is a very heavy weight, and it is inconvenient to carry it. Lord Luo gave the golden ticket of Lutong Bank, which is backed by Wei Ting, and has a good reputation so far.

Of course, the defense of the country is currently undergoing drastic changes, and it is difficult to say what changes will be made in the economy and people's livelihood in the future. He Xiaoyuan and the two of them, as the doctors accompanying the team, dare to bargain with Lord Luo again.

Yan Saburo also heard Lord Luo's voice coming from outside: "Go check the well water...... Villagers' reaction......"

After all, this man was not at ease, and he had to thoroughly check whether the well water had been poisoned. However, He Xiaoyuan's ability to use poison is still above saving people, and Yan Saburo is not worried about what Lord Luo can find out.

The medical officers were all busy, and several of the doctors who accompanied the team stayed in the room and stood by, but they ended up idle.

The guards will not let the patients go back until they get better.

Yan Saburo went to the thatched house halfway. The land of reincarnation of grains here is hidden in the woods, and it is still some distance from the black stone house.

After he came out, he had just taken a scoop and took water from the stone mortar to flush his hand, when a Chitose voice suddenly sounded in his ears:

"King Wei has high-ranking people by his side, and I can feel their presence. ”

"They?" Yan Saburo subconsciously looked up at the heights. There is also a small solitary peak above, which is not high, but conspicuous. It seems that King Wei lives there.

"More than one. Chitose said coldly, "Some people are particularly good at the art of concealment, and their breath is not obvious, but I can still feel the danger. ”

"You can't beat it?"

His question was too simple and rude, Chitose choked up, and his voice was angry: "Nonsense! It's just that my wish is precious, and I can't waste it indiscriminately! If only the three of us make a move, we may not be able to get back the money this time!"

"Okay, I got it. "I just can't beat it. But Yan Saburo didn't argue, and the two of them knew it.

You must know that this time the wooden bell gave a red light task, and the reward was about a hundred times that of the green light task. Even so, she thought that she might lose money if she wasn't careful, so you can imagine how difficult it is for the people on the top of the mountain to deal with.
