For Lu Ning to say this, Zhu Yuanzhang naturally understands.

But he still thought about giving Lu Ning everything he could.

At this time, Lu Ning didn't think much about it, so he said to Zhu Yuanzhang.

"Uncle, I won't tell you about this cosmetics technique, but I have another business to tell you, if you promote it in the domestic products department, I am afraid it will be more than enough to earn you the title of duke."

After hearing this, Zhu Yuanzhang was stunned for an instant, you must know that now only Li Shanchang, Xu Da and others are the founding dukes, and even Liu Bowen is just an earl.

If this thing offered by Lu Ning can really make him a duke, then how much contribution he has to make to be worthy of this title.

Thinking of this, Zhu Yuanzhang couldn't help but tremble a little, but more moved.

Although he regarded Lu Ning as a nephew, he had no real blood relationship.

And he has never disclosed his identity as an emperor, and he is a businessman of the National Products Division in front of Zi'an.

But even so, Lu Ning did respect and filial piety to him very much, and regarded him as a real uncle.

In front of him, he is willing to share any kind of good things, never hides them, and has no selfishness at all.

Zhu Yuanzhang secretly decided that if it was, when his identity was made public, he would at least make Lu Ning a county king, no matter what system was not systematic, he must let this child not be wronged.

Lu Ning didn't know that Zhu Yuanzhang had thought so much for a while, so he just said with a smile.

"The current dignitaries and the girls in the various hooks are very fond of eating sugar, but my Daming's sugar making process really can't keep up with such a large output, resulting in the sugar being sold very expensive, and the quality may not be able to catch up."

Zhu Yuanzhang nodded, he also knew in his heart that what Lu Ning said made sense.

Today's sugar production is actually boiled with sugar water squeezed out of sugarcane, and then impurities are removed.

The sugar refined in this way must have a very small yield, and it is also a little black, and the impurities cannot be completely removed, but even so, it is already very rare.

Even in the homes of dignitaries and even Hou Bo, guests who can serve some sugar for entertainment are very in place.

He looked at Lu Ning and asked very puzzled.

"Could it be that Fei Zi'an can master a large number of sugar production processes and make more refined sugar?"

If that's the case, that's a big deal.

Facing Zhu Yuanzhang's question, Lu Ning replied with a smile.

"This is actually very simple, I think the production of this thing is at least much simpler than making cosmetics, I will teach you this process, you will not be able to make a great contribution in the domestic department."

After listening to this, Zhu Yuanzhang instantly understood that this was simply a money printing machine.

But he still had some concerns, so he asked.

"But there is another problem, we can't solve the need for sugarcane for sugar production for the time being, we don't have so much sugarcane, even if there is a refining process, what role can it play?"

Lu Ning smiled indifferently, and he told Zhu Yuanzhang.

"Uncle don't worry, my Huangzhuang experimental field grows a large number of sugar beets, which are also raw materials for making sugar, and I can teach you to make fine frosting with sugar beets."

Zhu Yuanzhang had never heard of what beet was, but when he heard the name, it should have something to do with sugar, so he asked.

"According to what you said, this beet is naturally a good thing, but whether it is easy to grow and whether it can produce a lot is also a question."

Lu Ning smiled, and he said directly to Zhu Yuanzhang.

"Sugar cane is not easy to grow, and it requires very fertile fields and climate, but sugar beet is less productive than potatoes, and it can be grown in any region."

Zhu Yuanzhang was overjoyed after hearing this, the yield is less than that of potatoes, which means that each mu of land can reach at least 1,000 catties.

If it is used to cure sugar, it is also equivalent to being inexhaustible, which is simply a treasury that is opening its doors.

Zhu Yuanzhang was also extremely excited, and he said to Lu Ning with a smile.

"Nowadays, there is too much demand for sugar in all parts of the Ming Dynasty, and now even if the frosting is the cheapest, it can be sold for more than a dozen taels of silver, and the better ones will cost more than 20 taels and one catty.

Lu Ning pursed his lips, looked at Zhu Yuanzhang helplessly and said.

"Uncle, if it weren't for your good facial features and kindness, I would have thought you were the emperor, and I would have been thinking about national affairs all day long."

Zhu Yuanzhang was a little speechless when he heard this, and he hurriedly asked Lu Ning.

"What do you mean, kid? Could it be that the emperor's face is not upright, and he is not kind? If Jin Yiwei listens to this, it is estimated that your head will have to move tomorrow. ”

Lu Ning looked around and saw that there was no one else, so he whispered to Zhu Yuanzhang.

"Don't joke with me, you are a person from the Department of Domestic Products, so you naturally have the opportunity to meet the emperor, then Zhu Yuanzhang has a shoehorn face, how ugly and ugly it is, if you see him, you can probably scare me."

After Zhu Yuanzhang heard this, his nose was almost crooked, the folk legend was so bad to abuse himself, but he didn't expect Lu Ning to believe it.

But he didn't have a seizure on the spot, so he had to pat Lu Ning on the shoulder and said.

"You must not believe this kind of hearsay, besides, if you accidentally pop out two sentences and let people grab the handle, it is not a joke."

Lu Ning nodded, he also knew that this was his uncle's concern for him, and it was naturally a big sin to joke with the emperor, so he immediately said with a smile.

"Uncle, don't worry, I will never make this kind of joke again in the future, let's talk about beet, and I'll take you to the Huangzhuang experimental field to have a look in a while."
