Because of the need for negotiation and bargaining chips, they were not in a hurry to take a boat, but borrowed a farmhouse near Zilingdu to rest for a while.

The people here in Fengcheng don't recognize them, and seeing that they are generous, they casually gave five taels of silver to buy some tea and food, and saw that although they have the color of wind and frost, they do not seem to be fierce and evil, so they are relieved to let them rest, and happily took five taels of silver to buy food.

This farmhouse is just a small family, of course there are no things such as pen, ink, paper and inkstone, but the efficiency of the shadow pavilion is beyond doubt, and the pen, ink, paper and inkstone were quickly prepared for Chi Xiaoman, and Xiaoman worked hard to write and complete a "negotiation letter" after a while.

And the people of the Shadow Pavilion also have their own ways to let this letter enter the imperial city smoothly and go to Xuanyuan Yu's hands.

The content of Chi Xiaoman's letter is very simple, but it clearly states that without her antidote, Emperor Xuanyuan will definitely die of poison within three months, and just tonight, Emperor Xuanyuan can feel the power of this poison.

However, if Emperor Xuanyuan can let them and Lord Su and his envoys return to Yasukuni safely, then she can offer the antidote.

Her letter made Wei Chimu also curious about the poison, and after the letter was sent out by the shadow, he couldn't help but ask: "That is the poison you developed yourself, why can you let Emperor Xuanyuan know the power of the poison tonight?"

"That poison is a kind of grass that I accidentally found in the Valley of Ten Thousand Poisons when I was in the Poison Doctor's Gate, and there is a list of the names of the herbs of that kind in the Ten Thousand Poison Doctor Sutra, and even a simple diagram is drawn, but it is noted in small print that the herb is extinct, but I found it by chance. ”

Chi Xiaoman paused for a moment and continued: "Of course, the poison I made is not only that kind of grass, but also other things, so that the imperial doctors can't solve what kind of poison their emperor has for a while. However, I have to admit that I am still not good at learning, so it will be a matter of time before the imperial doctor analyzes the poison in Xuanyuan Yu. ”

"So we don't have much time, do we?"

"You can say that, but there's no need to worry too much. After all, even if the imperial doctor identified the double grass, even the poison door doctor scripture said that it was extinct, and the same must be true of the medical canon here in the Shengxing Dynasty, but the imperial doctor would definitely think that the double grass still exists in the world, but it is just difficult to find. The world is so big, let them find it slowly! The harsh growing conditions of Shuangyi grass are not something that can be grown casually. "Chi Xiaoman is not too worried about the problem of time, I'm afraid that Xuanyuan Yu's mind has become elusive now, and I'm afraid that the negotiation is not as simple as himself.

Yu Chimu was a little interested in Shuangyi Cao, and anyway, he was just waiting for a response at the moment, so he asked: "Since you said that Shuangyi Cao must also be written in the medical canon that it is extinct, can you write what is the antidote to Shuangyi Cao?"

"Mu, it's rare to encounter something you don't understand, you haven't been able to hear the meaning of my words?" Chi Xiaoman said with a smile, feeling quite good about the rare stump.

Yu Chi Mu thought carefully about what she had just said, and then suddenly said: "Since you must find Shuangyi grass to detoxify, it means that it is both a poison and an antidote. ”

"Clever!" Chi Xiaoman explained: "Shuangyi grass has two leaves, one for poison and the other for detoxification, and it is always born in both ways. ”

These topics involve the emperor of the Shengxing Dynasty, after all, they can't say much, so after chatting for a while, they stopped the topic and talked about some gossip, and the owner of the farmer also bought the vegetables, although it is not as good as their usual daily food, but the farmhouse dishes occasionally eat and have a different taste.
