The first floor is more than saltpeter ice.

It's huge, the size of two acres of land.

There are all kinds of research, even the study of planting flowers and trees.

There are even a lot of strange studies that Fang Yuan doesn't know.

After visiting the first floor, Li Shimin and Du Ruhui were already feasting their eyes.

They saw saltpeter ice making, saw what the spring looked like, saw the process of roasting tea, and so on.

"There are the most people on the first floor, and there are all kinds of research, and there are many of them that I don't know."

Fang Yuan said.

Head the stairs to the second floor.

There are many stairs in the nine-story Mojia Research Institute, which are similar to the stairs of high-rise buildings in later generations.

Because it is not an elevator, there is no need for stairs on both sides, and only one side can be used to meet the needs of going up and down.

Seeing Fang Yuan walking up the stairs, the two of them also followed quickly, their hearts full of curiosity about what was being studied on the second floor.

However, just after walking half of the stairs, Du Ruhui coughed repeatedly, coughing his chest against his back.

"Is Steward Du unwell?"

Fang Yuan asked with concern.

After a moment's silence, he stepped back to hold him.

This is the staircase, and if you fall down, there could be a fatal accident here.

"Lao Du, are you okay?"

Li Shimin also looked at Du Ruhui with concerned eyes.

But he didn't hold on like Fang Yuan, he just looked at Du Ruhui from the upper steps.

As an emperor, the highest standard of his care for his courtiers is to understand the difficulties of his courtiers.

"Minister... Ahem, ahem... It's okay... cough cough cough ......"

Du Ruhui waved his hand.

But even though he was fine, he still coughed.

His health has always been bad, and he has slept comfortably and felt happy for the past two days.

But today, after walking for most of the day and climbing the stairs, I didn't pay attention to it all of a sudden, and I felt tired and coughed.

It's an old problem, and it's all coughing that can get better after a while.

"Are you okay?"

"Come, I'll help you to the lounge on the second floor."

Fang Yuan shook his head and said speechlessly.

With such a sick body, how can he be the butler of the representative of the royal caravan?

I don't understand, I really don't understand.

Fang Yuan half-carried Du Ruhui's body and walked up the remaining stairs.

The second floor is different from the first floor, there are corridors, divided into two sides, and there are doors locked, so you can't see the inside.

Because the center of the Nine-Layer Mojia Research Institute is hollow, it does not feel dark and oppressive.

There are several rooms on the second floor that have no doors, each of which is about 30 square meters, and the layout looks simple, like a study.

But this is actually a place to drink tea and rest, usually Fang Yuan or other people on the second floor will rest here for a while when they are tired, sit and drink tea or something.

Du Ruhui was still coughing, but it was much better than just now.

It's just that his face is sickly red, and it doesn't seem to be much better.

"This is Pu'er tea, which has the effect of clearing heat, expelling phlegm, and relieving cough, so you can drink a few more cups to try."

Fang Yuan selected a kind of tea and quickly brewed it for him.

The water was still hot, but Du Ruhui couldn't care about it so much, and the cough made him uncomfortable.

Immediately drank it with a grunt.

I don't know if it's the effect of Pu'er tea or the water soup, but after a cup of it, it immediately got a lot better, and people no longer coughed.

"It seems to work, you can take these back later."

"This tea is not sold outside, you tell the official before you leave, and the official will prepare some for you to take back."

Fang Yuan placed the whole pot of tea directly in front of Du Ruhui.

The tea culture in Wuling County has not yet been thoroughly popularized, and many teas have not yet appeared.

At present, the tea on the market is only produced and sold by Wuling County's own people, and the situation is known before it spreads outside.

"Thank you!"

Du Ruhui said gratefully.

He didn't know how precious tea was, but Fang Yuan's concern was genuine.

When he didn't know his true identity and thought he was just a mere housekeeper, he could still treat himself like this, which made Du Ruhui sigh and sigh.

At this moment, Du Ruhui was truly determined to cultivate Fang Yuan, even if Fang Yuan's life style had a groove.

"Drink more."

Fang Yuan chuckled and ignored it.

When pouring tea for him, he also poured tea for Li Shimin.

Li Shimin sat on the other side and looked at Du Ruhui with concern.

Seeing that Du Ruhui was no longer coughing, he was also relieved.

This courtier, who is loyal to him, is getting worse and worse, and I am afraid that time is running out, alas......

"yes, okay."

Du Ruhui reciprocated with a smile.

If you're grateful, people of his rank don't like to talk too much.

Five months later, Fang Yuan's transfer, he would help Fang Yuan as much as possible.

Even if it is not a promotion assassin history, he will not serve as a county commander in the middle county, and he will definitely be transferred to the big county.

In Du Ruhui's view, although Fang Yuan made a bet with Li Shimin, with his understanding of Li Shimin, he may not necessarily succeed.

After a short break, Li Shimin proposed to continue the visit.

"The rest won't be visited."

"Most of the above the second floor are being studied, and there is no value for visiting."

"And Steward Du is not in good health, and climbing the stairs has a great impact."

Fang Yuan shook his head and refused.

Originally, he just wanted to show the two of them around the first floor.

There are some things above the second floor that are relatively secret, and they have a great influence on the times.

Before he was ready, Fang Yuan didn't want to show his hole cards in front of anyone.

"Didn't Fang Xianzun say to gamble with me?"

Li Shimin's face suddenly darkened.

My heart was completely aroused, but I said I wouldn't visit.

How dare he say such an excessive thing to me?

"Boss Li can't be angry."

"The official said to take you to visit the Mojia Research Institute, but the official didn't say to visit all the places."

"If Boss Li is unwilling to keep his promise, even if I take you to visit the ninth floor, you may say that there are other corners that you haven't visited."

Fang Yuan shook his head and said indifferently.

A gamble is just a gamble.

Gambling is risky in itself, and the bet is completely in the hands of the other party.

Although Li Daye said that he could help him be promoted to the history of assassination, but for now, he is just talking, and he won't help himself after reading his hole cards?

It's better to completely arouse the other party's interest as it is now, and then turn it into himself to gain the initiative, and if he wants to continue to visit, he will help himself first.

The bet cannot be completely dominated by the other party.

"Is Fang Xianzun afraid that I won't fulfill my promise after the visit?"

Li Shimin was stunned for a moment, then understood, and couldn't help but laugh angrily.

I am the Son of Heaven, and I am a man of my word, how can what I have said not count?

Fang Yuan shrugged, and it was self-evident that he admitted the other party's doubts.

"Can't you let me have a tour first?"

Li Shimin's heart was itchy, and he felt so uncomfortable.

Looking at Fang Yuan's indifferent appearance of drinking tea, he really wanted to punch Fang Yuan in the face.

"Boss Li is also a big businessman."

"Those who do big business should understand that the bigger the business, the less rush they can't have."

"If the position of my assassination history is confirmed, the Mojia Research Institute will always be open to Boss Li."

Fang Yuan said indifferently.

Li Shimin's questioning was ignored.

The more anxious the other party is, the more the initiative shifts to their side.

"You bastard!"

Li Shimin gritted his teeth angrily.

The words are nice, but Wuling County is so far away from you, so you may come often?

"Ahem, sir, why don't you do it today."

"Fang Xianzun also took us to visit the Mojia Research Institute."

Du Ruhui coughed dryly and interjected.

When the words fell, Li Shimin looked at Du Ruhui and was surprised.

This is his loyal old minister, how can he speak for others?

Fang Yuan was also surprised, but he just glanced at the other party and continued to drink tea.
