The eldest grandson Wuji was able to achieve the position of the "first brother of the court" in the Tang Dynasty, and he did not succeed in ascending to the throne just by relying on the nepotism of the eldest grandson queen, he also had extraordinary decisiveness.

And because he knows who he is, he has a clear distinction between public and private.

When he heard Gao Ming say that he handed over 10 million yuan to Li Shimin, he immediately put aside the trivial matter of his grandson's name, and began to plan in his mind how to use this huge amount of money to make Datang even stronger.

He thought for a moment, and then arched towards Gao Ming again.

"His Royal Highness the Prince, Wechen thinks that this money should be used to build academies first, like the kind of royal academies you built in Jinzhou, Your Highness, Wechen thinks that one should also be built in Chang'an, Jingzhao, Luoyang, Taiyuan and other places, and about cultivating a group of tax officials, Wechen thinks ......"

"Wait!"

Before Eldest Sun Wuji finished speaking, Gao Ming lifted up towards him.

"I'm just here to visit my sister today, so don't talk to me about business, if you have something to say, you can tell him in person when my old man comes back!"

Hearing that Gao Ming was reluctant to talk about business, the eldest grandson Wuji suddenly showed a wry smile, but he couldn't say anything, after all, Gao Ming had already said that this time he came to see his sister.

The most important thing is that Princess Changle is still the daughter-in-law of his eldest grandson Wuji, and he has no reason to object to it in public or private.

Therefore, the eldest grandson Wuji could only bow to Gao Ming Gong again.

"Thank you, Your Royal Highness the Prince, for your concern!"

"Well, you're welcome, by the way, I don't see any blood on her face, what do you usually give her to eat?"

Hearing Gao Ming's words, Eldest Sun Wuji immediately sighed.

"Alas, speaking of this old minister, he is also worried, the old minister asked him to prepare the ginseng chicken soup, the princess is tired of it, she won't eat it after a few meals, and the fish soup princess is fishy, and she is disgusted with beef and mutton, especially in the past two days, she doesn't even want to drink goat's milk, only willing to eat some vegetables and white porridge."

As soon as the eldest grandson Wuji's words fell, Gao Ming immediately frowned.

"How can you just eat white porridge and vegetables? If it really doesn't work, you can boil some brown sugar water for her to drink! ”

"Brown sugar water?"

Hearing Gao Ming's words, Eldest Sun Wuji immediately frowned, and then arched towards Gao Ming again.

"Your Highness, please forgive the old minister for being ignorant, I don't know what this brown sugar water is? Please also ask Your Highness to inform me, and the old minister will immediately order someone to find it! ”

"Uh......"

Gao Ming was stunned at this time, because at this time he suddenly remembered that Datang didn't seem to have brown sugar at this time.

According to historical records, it was not until Xuanzang returned from his westward journey that about two years later Li Shimin sent people to India to learn how to boil brown sugar.

Thinking of this, Gao Ming immediately sighed, and then swung towards the eldest grandson Wuji.

"Alas, it's not that you're ignorant, it's that I'm negligent, and now no one in this Datang should know how to boil sugar, or I'll do it myself, by the way, do you have sugarcane here?"

"Yes! Some! ”

As soon as Gao Ming's words fell, the eldest grandson Wuji hurriedly nodded.

"Princess, she usually likes to drink cane syrup the most, so every year the old minister will specially let people transport some back from the south, but the imperial doctor said that sugarcane is cold, and the princess's current situation is not suitable for drinking."

Hearing the words of the eldest grandson Wuji, Gao Ming immediately laughed.

"It's okay, the boiled brown sugar is fine, you can let someone squeeze out the cane syrup first, and then let someone clean the stove in the kitchen, I will use it later, and prepare some lime."

"Okay, I got it!"

Although the eldest grandson Wuji didn't know what Gao Ming planned to do, he knew that Gao Ming's request must have his intentions, so he immediately asked the family to squeeze the sugarcane juice.

The eldest grandson Wuji did not guess wrong, Gao Ming did have his own intentions, and his intention was to boil the first batch of brown sugar in the Tang Dynasty!

Gao Ming's hometown makes a living by boiling brown sugar, so he is also half a master of this art, although he may not be able to boil brown sugar with good color, but if he just gets this thing out, it is still no problem.

He had already planned to give half of the brown sugar to Li Lizhi after getting it out, and take the other half away by himself, and when Su Wan'er gave birth to a child, boil brown sugar eggs for her to eat, and make up for it.

This is also a rainy day!

The work efficiency of the family members of the Changsun Mansion is still very high, and with the order of the eldest grandson Wuji, they moved the large bundles of sugarcane to the backyard, and then squeezed the sugarcane juice out with a stone mill.

Gao Ming stood and watched, and when the family had filled the four buckets of sugar cane juice, he immediately swung towards them.

"Okay, someone will help me and send all this sugar cane juice to the kitchen, and the rest of the people will continue to squeeze it."

After speaking, Gao Ming took the lead in picking up two buckets of sugarcane juice and walked towards the kitchen.

Seeing this scene, the eldest grandson Wuji was not empty, so he hurriedly stepped forward to lift two buckets, then gasped, and followed Gao Ming to the kitchen.

When Gao Ming came to the kitchen, the family had already built a fire under the stove, so he directly poured all the sugarcane water in the bucket into the pot, and then instructed the family next to him.

"You're guarding the fire here, and the fire can't be broken, you know?"

"Yes!"

After instructing the family to light the fire, Gao Ming found another maid and handed her a spoon.

"You just stay by the pot, and when the water boils, scoop up the floating foam, and when there is no more foam, you pour this pot of sugar water into the pot next to it and continue to boil, and then boil new ones in this pot, and call me when the pot next to it is almost full, you know?"

"Yes!"

Hearing that the maid agreed, Gao Ming nodded, then walked out of the kitchen and asked the eldest grandson Wuji.

"Uncle, did you get the lime I wanted?"

As soon as Gao Ming's words fell, Eldest Sun Wuji immediately nodded.

"Get it, it's in the front yard, Your Highness, please come with me!"

"Hmm!"

Gao Ming followed the eldest grandson Wuji to the front yard, and sure enough, he found a basket of quicklime there, so he immediately asked people to find a basin, put quicklime in it, and add water.

What Gao Ming has done now is to turn quicklime into mature lime so that it can be used to make sugar cane juice acidic, which is one of the important steps in boiling brown sugar.

Eldest Sun Wuji didn't know this, and he frowned immediately as he watched the water and lime boiling in the basin and bursts of white smoke coming out.

"His Royal Highness the Crown Prince, you are ......"

Looking at the eldest grandson Wuji's frowning brows, Gao Ming was not mentally retarded enough to explain the difference between calcium oxide and calcium hydroxide to him, but directly gave him a mysterious smile.

"You'll find out later!"

“……”

If someone else said this to him, Eldest Sun Wuji would definitely be a slap in the face, but in the face of Gao Ming, he could only show a stiff smile, pretending to be happy and looking forward to it.

"Ahh I see, the old minister will wait and see, hehe......"
