How could my childhood sweetheart be the current empress?

Fortunately, Xu Chengling's yard was relatively large, so he placed the distillation device on the west side of the yard, leaving space for the middle yard.

Following the method given by Xu Chengling, several dexterous servants began to work and built a simple distillation device in his yard.

They didn't know why the master was doing this, but since it was the master's order after all, they didn't think much about it.

In the distillation device, Xu Chengling chose a clay jar with strong heat permeability as the bottle used for heating, and replaced the condenser with a bamboo cut in half. As for the beaker for collecting allicin, he used a porcelain bottle.

After a long time and with everyone's efforts, the proposed distillation device was finally built.

"Master, what are you doing with this big thing in the yard?"

The servants were all a little puzzled. They had never seen this thing before and had no idea what it was used for.

In response, Xu Chengling just smiled and said:

"This thing is very useful. You have all worked hard. Go back and rest early."

"Yes, sir."

After the servants left, Xu Chengling looked at the device in front of him and felt delighted. This thing had more uses than just that. The distillation device could not only be used to extract allicin, but also to extract plant essential oils.

Plant essential oils are the raw materials used to make perfume.

"When there's a chance in the future, I'll make a perfume for my wife."

Xu Chengling thought, now that he had already built the distillation device, it would be a shame not to make some perfume for his wife.

Of course, he didn't know what flavor his wife liked, so he had to wait until she came back to find out.

There's still a lot of room for improvement in this simple distillation device, but it's good enough for now.

At this time, Tongxin also came back with a bag in her hand, which emitted a pungent smell.

"Master, I bought the garlic you requested."

"Well, just put it here."

Xu Chengling nodded and signaled Tongxin to put the garlic here as he would need it later.

Until now, Tong Xin still didn't know what Xu Chengling was going to do, so she asked curiously:

"Master, you bought so much garlic and made such a big thing. Could it be related to the little princess's illness?"

"Yes, that's really smart."

Xu Chengling touched Tongxin's soft hair. This girl was so smart that she guessed what he wanted to do.

He didn't hide anything and directly explained to Tongxin how to use this big thing in front of him and a drug called allicin that he wanted to extract.

After listening to this, Tong Xin was surprised and asked:

"Master, is this garlic essence really as magical as you said?"

Xu Chengling nodded and said confidently:

"That's natural. Especially for the treatment of diseases such as whooping cough, allicin is definitely a special medicine. If it can be popularized in the future, I don't know how many lives it can save."

Tongxin was stunned as she listened. For some reason, she always felt that the image of the master was gradually becoming more majestic.

But no matter what, as long as it is what the master wants to do, she will support it unconditionally.

"Okay, now I'm going to start extracting allicin. Tong'er, come and help me."

Xu Chengling looked at the pile of garlic in front of him. Although it looked like a lot, he didn't know how much allicin could be extracted in the end.

Xu Chengling did it right away. Following the instructions in the time traveler's guide, he crushed some garlic, poured it into a clay pot used for heating, and added water.

The next step is to add firewood to the bottom of the clay pot and heat it slightly after it boils.

After a while, mist was seen rising above the earthen jar. The mist rose and hit the bamboo strips, condensed into dewdrops on the bamboo strips, and then dripped downwards, eventually flowing to the porcelain bottle used to collect the allicin liquid.

Soon, the water in the earthenware jar was evaporated. Xu Chengling was already sweating from exhaustion. He quickly got up and looked at the porcelain bottle that collected the allicin.

"Great, it really works."

At this time, Xu Chengling saw some sticky light yellow liquid in the porcelain bottle, along with a strong smell of garlic, which was exactly the allicin he wanted to extract.

But to his disappointment, the amount of allicin seemed a little low.

It seems that not enough allicin can be extracted from these two kilograms of garlic.

This amount of allicin alone is obviously not enough to cure Yan Ruoyao's whooping cough, let alone mass production.

"Tong'er, go to the medicine store tomorrow and buy ten kilograms of garlic."

Xu Chengling said to Tongxin, and then he continued to extract.

After a long time, he finally extracted all the two kilograms of garlic and finally got a small bottle of allicin.

On the second and third days, Xu Chengling stayed in the yard, tinkering with the distillation device.

After a few days of improvements, the extraction efficiency of this simple device has been greatly improved. Now two kilograms of garlic can extract twice as much allicin as before.

Finally, Xu Chengling got a bottle full of yellow-brown liquid with a pungent smell.

As agreed, Xu Chengling, under the protection of Tongxin, visited Prince Xian's Mansion again with the bottle of allicin.

"Prime Minister Xu, you are finally here. The flowers I have been waiting for you for are all withered. Did you bring the things?"

When he saw Xu Chengling, the wise king immediately greeted him warmly, as if he had met his long-lost brother.

"I brought it. My medicine is very useful."

Xu Chengling nodded, smiled slightly, and took out a bottle of yellow-brown liquid from his pocket.

He opened the bottle slightly, and for a moment, a pungent smell rushed over, so much so that the wise king could not help but cover his nose quickly.

"Xu Xiangguo, what is this thing that smells so strong?"

The wise king frowned and looked at the small bottle in Xu Chengling's hand. Could this thing be for Yaoer to drink?

"This is a special medicine for treating whooping cough. I have brought it with me. It is up to you, the wise king, to decide whether to use it or not. Anyway, I cannot make a second bottle of this special medicine, so once it is used up, it will be gone."

"Tong'er, let's go."

After giving the allicin in the bottle to Queen Xian, Xu Chengling left with Tongxin.

He knew in his heart that the wise king had even used fasting therapy, so this one wouldn't be a big deal.

After he left, the wise king tightly grasped the small bottle in his hand, and after much hesitation, he decided to trust Xu Chengling once.

The virtuous king came to where Yan Ruoyao lived. Before he arrived, he heard a familiar cough coming from the front, which made him feel really distressed.

He couldn't help but hold the bottle tightly and walked into Yan Ruoyao's room, only to see her lying in bed, her face pale and without a trace of blood.

"Ahem... Daddy, you're here."

"Yao'er, Daddy brought you a special medicine, it will definitely cure you this time."

As he spoke, the virtuous king poured the allicin in the bottle into a bowl and fed it into Yan Ruoyao's mouth.

"The taste may be a little irritating, Yao'er, just bear with it for a while."

"Ah."

Yan Ruoyao endured the pungent smell and finished the bowl of allicin.

After a while, she fell into a deep sleep.

The wise king was worried and stayed by his daughter's bedside.

It was not until the evening that Yan Ruoyao slowly woke up, but this time, she did not cough as usual.

Yan Ruoyao couldn't help but suddenly discovered with surprise that her throat seemed to be much more relaxed and she didn't want to cough as much anymore.

"Dad, Yao'er seems to have stopped coughing and feels much better."

"is this real?"

The wise king looked at his daughter in disbelief, only to see that Yan Ruoyao's complexion had gradually regained some of its rosiness, and most importantly, she had stopped coughing!

"Prime Minister Xu, his medicine is really useful!"

Seeing Yan Ruoyao gradually recovering, the virtuous king was so happy that he even wanted to run directly to the Prime Minister's Mansion and kowtow to Xu Chengling.

Chapter 100 He is like a delicious cookie

The wise king was extremely happy these days.

Ever since taking the special medicine given by Xu Chengling, Yan Ruoyao has gradually stopped coughing and her complexion has gradually improved.

The most important thing is that Yaoer can actually get out of bed and run, and her originally frail body is slowly recovering.

You know, in the past, due to Yaoer's physical condition, she would stop to catch her breath after a short jog.

But now, her legs are no longer sore, her waist no longer hurts, and she can climb to the fifth floor in one breath without any effort.

You tell me, seeing his daughter getting better and better, how could he not be happy as a father?

All this was thanks to the special medicine that Xu Chengling sent him. It not only cured Yan Ruoyao's illness, but also improved her naturally weak constitution.

"Yao'er, come here for a moment."

At this time, the virtuous king called Yan Ruoyao who was walking in the yard. She looked much better today than yesterday.

"Daddy, what's the matter?"

Yan Ruoyao opened her watery eyes and asked the man in the python robe in front of her.

"Yao'er, how is your body now? Are you still coughing?"

The virtuous king asked with concern, only to see Yan Ruoyao gently shook her head and said:

"Yao'er's health has improved a lot. She hasn't coughed in the past few days, and her throat feels much better."

Yan Ruoyao said calmly, her voice was much clearer than before, she couldn't help but ask curiously:

"Dad, where did you get this magic medicine? It's so effective."

"This is the special medicine sent by Prime Minister Xu. He said that this medicine is very useful and can cure your illness. Hahaha, he really didn't lie to me."

The wise king couldn't help but touch his stubbled chin and said happily.

"It turned out to be Brother Xu who sent the medicine. I am so grateful to him."

Hearing that it was Xu Chengling who sent the medicine, Yan Ruoyao couldn't help but feel deeply moved and full of gratitude towards him.

Since taking his medicine, Yan Ruoyao has never felt so relaxed. If she meets him again next time, she will definitely thank him very much.

At this time, the wise king also said:

"Yes, this is all thanks to Prime Minister Xu. We must go to his house in person to thank him someday."

Having said that, the wise king couldn't help but look at his daughter in front of him. Yao'er inherited her mother's appearance, and also inherited a bit of his majesty. She was so beautiful.

So he looked at his daughter and said casually:

"It would not be too much to repay this life-saving grace with my own body."

"Ah, Daddy, what are you talking about?"

Yan Ruoyao's pretty face turned red, and her face was hot as if it was on fire.

She lowered her head and said in a very low voice:

"Yao'er is still young and hasn't decided who she will marry in the future."

"Haha, that's right. Yao'er can marry whoever she wants in the future. Daddy was just saying that casually."

The wise king laughed and teased his daughter on purpose.

"Dad, don't talk nonsense. Yao'er doesn't think so..."

Yan Ruoyao blushed and turned her head away shyly.

But as the saying goes, no one knows a daughter better than her father. How could Yao'er hide her little thoughts from him as her father?

He saw the reluctance in Yan Ruoyao's eyes when she broke up with Xu Chengling. Now that she mentioned him again, her eyes were almost full of peach blossoms.

But if you think about it carefully, Xu Chengling has already become the prime minister at such a young age, which means he is definitely a rare talent. In addition, he is handsome, which girl would not be attracted to him?

Because of her weak health, Yao'er seldom goes out, and the only man she sees on weekdays is this old man.

Now she suddenly meets a successful, young, handsome, gentle and considerate man who saved her life. How can she not be tempted?
