Xin Yi was woken up by a series of firecrackers.

The artillery of this era was no worse than that of later generations, and the sound came in the silent early morning, shocking half the sky.

Xin Yi opened the tent uneasily.

"Apricot round."

Xingyuan came over, "Lady, why are you awake?"

Xin Yi pressed his forehead, "Didn't you hear the sound of the cannonball?"

Xingyuan pricked up her ears and listened for a moment, "I heard it now, like a ...... from the other side of the street."

Maybe it's because the crossing has an innate advantage, Xin Yi is better than ordinary people in terms of strength, smell and hearing, but Xingyuan is not so sensitive.

"Has Silver Frost flown back?"

Xingyuan shook her head.

"It's going to take a lot of time to go back and forth, and with boats coming and going on the river, Silver Frost must have taken some time to find the king."

Xin Yi smiled, "You think Silver Frost looks like you."

Xingyuan smiled embarrassedly, "Then go and take a look......

The cage of the silver frost was placed by the window of the transept, empty, where were the birds?

Xin Yi sat up from the bed, his unwashed little face full of worry, "No, I can't just sit and wait in Beijing......

It was extremely cold at night on this day, Xingyuan saw that she was thinly dressed, for fear that she would catch a cold, so she quickly pulled up the quilt and wrapped her body.

"What is the lady going to do? Is it ......?"

Before her voice fell, Xin Yi had already answered, "Go to Yangzhou."

"Ahh Xingyuan has always been a calm character, and she was so shocked that she couldn't speak.

"The princess of the county is going at this time, but I am afraid that the eldest princess will not be able to explain it to her, and besides, it is not safe without the escort of the princess......

"If you can't explain it, you can find a way. Can a living person be suffocated by urine?" Xin Yi lifted the quilt and sat on the edge of the bed, found that her body had sunk a lot, and subconsciously stroked her lower abdomen, she said:

"Don't sleep, change my clothes. I'll have to get up and pick it up."

Xing Chengcheng was in a hurry, "It's not dawn yet, what is the lady going to do......?"

Xin Yi didn't seem to hear, his eyes lowered and looked at his feet, his thoughts drifting away.

After a while, she sat down in front of the bookcase, Xingyuan holding the fire cage next to her, yawning and grinding the ink.

Xin Yi glanced at her, "You go down to sleep."

"Oh." Xingyuan knew that the master wanted to write at this time, and she didn't want her to wait by her side, so she walked away.

Xin Yi buried his head at the desk, and wrote and drew on the paper by the dim light.

Today is the twenty-eighth day of the first month of the second year of Zhihe, and it has been ten days since Yu Du, the son of Qingyu, came to the pharmacy for the first time to consult her.

The reason that prompted Xin Yi to write that letter to Fu Jiuqu was the illness of Qingyu Gongzi, as well as his coming from Yangzhou, etc., and thought of a side quest in "Bianjing Fu".

——Yangzhou strange disease.

It was that kind of disease that Qingyu Gongzi suffered.

The condition comes from the setting of the Chinese medicine team, which is similar to typhoid fever, and the treatment is not complicated.

The first time he gave Fang, Xin Yi used the treatment plan he had originally set, which was the same as the one passed to Fu Jiuqu. It is said that after taking Qingyu Gongzi, there will be a significant improvement.

However, three days later, Qingyu Gongzi came to the door again, still coughing badly.

Not only that, but he also suffered from nausea and vomiting, drowsiness, diarrhea, and blood in the stool, and his condition clearly worsened.

This is equivalent to a disease cured by Xin Yi's hands.

Xin Yi did not prescribe medicine this time, but told him to bring the prescriptions and medicine residues he had taken before. It's a pity that there is no abnormality in the prescription, it is a normal typhoid prescription, which is basically symptomatic.

But he couldn't find the used dregs.

Xin Yi consulted again and found that he had kidney damage and suspected that he had been poisoned.

However, Qingyu Gongzi thought that he had no enemies, let alone made enemies with others, and his diet was even more ordinary, so he couldn't think of the possibility of poisoning at all. And at the moment, Xin Yi has no way to do a toxicity test for him.

Seeing that his health is healing

In desperation, Xin Yi had no choice but to admit him to the ward of the medicine shop, instruct two men to take care of him, and let Ge Huan observe him at any time.

After nearly seven days of treatment, Qingyu Gongzi's health improved significantly.

But Xin Yi still couldn't sleep.

She felt that there must be something wrong with this......

From Qingyu Gongzi's "Song of the Cave Immortals" to the strange illness without a clue, she has an unfounded but very certain sixth sense, and there must be some kind of connection between these things.

is in the plot, and it is outside the plot, a line that is not known to her and Fu Jiuqu. She even felt that it might be related to what Fu Jiuqu said, the deleted treasure of the Southern Tang Dynasty.

She wrote to ask Fu Jiuqu's opinion, after all, he was the one who had seen the original version, however, Silver Frost was gone, and she had to worry about the safety of Silver Frost in addition to the change of things.

The lights went off slightly.

Xin Yi came back to his senses and looked at the clues written on the paper.

Song of the Cave Immortals - Hidden Treasure of the Southern Tang Dynasty - Strange Disease of Yangzhou - King of the Plains - Black Powder Workshop - Qingyu Gongzi -

The events and characters that she strung together with threads were magnified little by little in front of her eyes.

Suddenly, a flash of inspiration flashed through her mind.

"Aristolochia."

Aristolochia is a traditional Chinese medicine.

Cough and asthma, suitable for cough, chest tightness, phlegm yellow pulmonary carbuncle ......

At the same time, aristolochic acid contains aristolochic acid, which has obvious nephrotoxic and carcinogenic effects, can cause diarrhea and blood in the stool and other symptoms, and has a fatal effect on patients with poor kidney function.

But that's not the case with Xin Yi's concerns......

She picked up her pen and drew a circle on the Black Powder Workshop.

Aristolochia is a traditional Chinese medicine, and it is also a medicine that can start a fire, and it is charcoal when burned, which can be used to make black powder. Initially, gunpowder was discovered and used by humans in Liandan, and there was a figure of aristolochia. Chinese Net

"Two taels of sulfur, two taels of nitrate, three and a half cents of aristolochia......

Xin Yi inexplicably thought of the process of the invention of black powder, and his mind was buzzing.

"Isn't it more convenient to use charcoal to make black powder?"

By the time it was daylight, a thin layer of fine sweat had oozed from her spine.

Xingyuan knocked on the door and came in, and was startled when she saw her face flushed, "What's wrong with the lady?"

Xin Yi casually tore up the white paper he had written, threw it into the fire cage, watched the flames lick up, and loosened the ties of the loose fur.

"The fire cage was so close that it almost roasted me."

Xingyuan snorted and smiled and stepped forward to wipe her sweat.

"Lady, Silver Frost has flown back."

Xin Yi was stunned, where can he still sit still?

She brushed away Xingyuan's hand, opened the door in three steps and went out in two steps.

When the cold wind blew, she sneezed, and the birds, which were pecking on the windowsill, heard the sound and flapped their wings and flew towards her.

This bird is very human.

As soon as Xin Yi stretched out his arm, it stopped on it and pecked her affectionately.

"You're scared the hell out of me." Xin Yi grabbed Yinshuang and subconsciously went to get the letter on her ankle ring.

A small piece of paper was rolled into a paper tube, four simple words.

"Thank you for letting me know."

That's it?

When she sent the letter, in addition to attaching a prescription, she also specially explained Qingyu Gongzi's consultation and her doubts. Why does this person seem to be incomprehensible?

Xin Yi took a breath and felt cold from his nose to his mouth.

Alas! After all, it's not Brother Jiu, and he has less tacit understanding with her.

"Lady, what did the county king say?" Xingyuan looked at her back and asked in a low voice.

Xin Yi rolled the note into his sleeve, "You take care of Silver Frost and wait until I get back from the medicine shop."

··

The wind is bleak and the water is cold, and the temperature has dropped today, and Bianjing City is cold.

Seeing today's tabloid in the pharmacy, Xin Yi knew why the artillery battle in the early morning was.

The scholar of the Guanwen Temple and the secretary of the military department, Yan Zhu, is gone.

This famous politician and writer, who entered the test as a prodigy, once ruled the world, and had a far-reaching impact on the Northern Song Dynasty court, died in this winter.

"Helplessly, the flowers are gone, and the familiar swallow returns."

Xin Yi stood on the wooden platform on the second floor, looking at the water of the Wuzhang River, reading Yan Zhu's words, thinking that he was in the same era as the great poet, and he was in a trance.

"Last night, the west wind withered the green trees, and I went up to the tall building alone, looking at the end of the world......

Suddenly there was a chant in the courtyard, accompanied by a heavy cough. Xin Yi looked down and saw a young jade boy dressed in white and alone.

She frowned, fastened her shackles and went down to the courtyard.

"Why don't you rest in the ward? It's cold outside, and it's not good for your recovery."

Yu Du heard her voice, slowly turned his head, showed a shallow smile at her, and then bowed.

"Thank you for your care, I feel good today, I have been lying down for many days, my body is tired, I want to come out for a walk, breathe......

Xin Yi tilted his head disapprovingly.

"Go in and lie down."

treats this kind of patient who is pulled back from the ghost gate, and she doesn't take care of her body, she doesn't give a good face.

Yu Du is also used to her domineering.

"Yes. Obey the lady's instructions......

Xin Yi's tone softened slightly, "Go in, I'll have someone bring you something soft and delicious."

After arranging Yudu's affairs, Xin Yi returned to the second floor and leaned on the couch, ready to take a nap. Taoyu and Xiangling pulled the tent for her, and retreated silently.

She was already sleepy with her pregnant body, and she didn't sleep well last night, so she fell asleep unconsciously.

In a hazy state of consciousness, she suddenly noticed a slight noise in the window.

The footsteps of the visitor were so fast that she didn't have time to react, and a burst of cold air slipped into the tent.

She instinctively hugged the quilt, "Who ......?"

The cold palm covered her mouth.

The man leaned down, staring at her with a cold face, "It's me."
