Li Shimin's excited eyebrows and mustache jumped together.

Li Yuan also looked like he was listening.

"Gen'er, do you know the way of making salt?"

"Dad, it's a very simple thing, if it weren't for the imperial court's salt control, the child would be able to produce a large amount of salt casually, and it would be much finer than the current refined salt."

Li Shimin stood up excitedly.

"Gen'er, is this true?"

"Son, when did you deceive your father?"

"Okay, it's really good, Gen'er helped his father this time to solve a big problem."

Li Shimin picked up his wine glass and raised his head to drink.

Putting down the wine glass, Li Shimin suddenly looked at Li Gen and spoke.

"Gen'er, but there are no salt mines around Chang'an City, and some are also poisonous salt mines."

Li Gen nodded and said when he heard this.

"Dad, the poisonous salt mine is fine, the child naturally has a way to get rid of the poison."

"Well, that's great, so my father can rest assured."

The biggest problem in Li Shimin's heart, I didn't expect it to be solved by Li Gen.

The happy Li Shimin drank a few more glasses.

After the banquet, the father and son sat opposite each other.

Tell about these days, their lives and experiences.

Li Yuan and Changle left the room with interest.

Give them father and son, and leave some time to say thoughtful words.

The father is proud of his son, and the son is happy for his father.

Father and son, a chat is more than an hour.

It wasn't until Zhao Si, Feng Wu and others returned from the restaurant that the conversation between Li Shimin and Li Gen came to an end.

"Zhao Si, Feng Wu, you bring some people, put on a carriage, and go to pull a few carts of salt mines back."

"Young master, those are all poisonous salt mines."

Listening to Zhao Si's words, Li Gen said with a smile.

"Go ahead, Ben Gongzi, it will naturally be poisoned."

Zhao Si and Feng Wu glanced at Li Shimin and immediately did as Li Gen instructed.

Before dark.

Six carriages were loaded with salt mines, and Zhao Si and Feng Wu led everyone into the manor together.

"Chunmei, Chunlan, Chunzhu, Chunju, prepare more meals tonight, everyone has worked hard all night, and then add another meal."

Li Gen has already decided, him tonight.

After all, it was something my father desperately needed.

In addition, the weather is too hot during the day to be in the open air, and it is not suitable for strenuous labor.

Many tools, Li Gen has made light and bright, and went to the market to buy them back.

As long as Li Gen makes a slight change, he can make do with it.

Now is not the era of the later generations, where all kinds of tools and instruments are extremely sophisticated.

If it can be operated by hand, it is enough to produce refined salt.

The sun is setting, and it's the hottest time of the day.

Li Shimin looked at the large sweet potato field, and was naturally shocked again.

"Dad, in another month, it will almost be ready for harvesting, and the child has put a lot of fertilizer on it to ensure that it is juicy, sweet and delicious."

Li Shimin hurriedly asked, what kind of fertilizer is on it.

After all, in the imperial garden of his palace, there are five sweet potato seedlings!

"Dad, it's all the purest fertilizer, human, cow, sheep, pig, chicken, duck and goose dung......"

When Li Shimin heard this, his face was full of black lines.

It's fucking, it's really fat and juicy.

But can it be sweet and tasty?

"Gen'er, how big does that smell like these things?"

Li Gen scratched his head when he heard the words and said.

"Dad, no wonder my grandfather said that you didn't do your business before, it seems that it really lives up to its name, the tricks in this crop field, you are six tricks and five tricks, and you don't know anything!"

Seeing that his father was quite displeased, Li Gen smiled and said.

"Dad, I'm kidding you, it used to be before, and now you are a good official who is dedicated to the people, and the child is proud and proud of you!"

Li Gen's vernacular made Li Shimin laugh happily again.

"Young master, everything is ready according to your requirements."

After listening to Zhao Si's words, Li Gen nodded with satisfaction.

"Let's rest, and after dinner, we can get back to work."

"Dad, let's go back to the house, Gen'er will write down the salt-making technique for you in detail, but any craftsman who can read will understand it."

"Good!"

There is nothing more pleasing to Li Shimin than this sentence.

Father and son returned to the house.

Changle naturally followed behind.

I saw my brother take out the four treasures of the study.

The little girl came over to study ink very eye-catchingly, and Li Shimin was envious.

In the palace, this girl has never studied ink for anyone, including him Li Shimin.

Unexpectedly, it has only been a long time since I came to the manor.

It's so well-behaved and sensible.

"Lele, you can be so well-behaved and sensible, I am very pleased to be my father!"

Li Shimin opened his mouth and praised.

"Dad, don't you tell Lele, the eldest brother is like a father, Lele keeps it in mind, and naturally wants to study ink for his brother!"

Li Shimin almost spurted out a mouthful of old blood.

This girl is really deliberately angry with herself, since she knows that her eldest brother is like a father, why don't she study ink for Lao Tzu in the palace?

"Dad, Lele is really well-behaved and sensible, Gen'er will definitely take care of her, there will be nothing to do in the future, Gen'er decided to teach Lele homework."

"Well, it's good to be a father!"

Li Shimin nodded approvingly, letting Changle do more homework is also a good thing after all.

Li Gen spread out the rice paper.

Pick up the pen and dip it in ink, and then start drawing and writing.

It's the process of painting that works.

What is written is a note.

Li Shimin watched quietly from the side.

While watching, Li Shimin was amazed in his heart.

Sure enough, it's easy to understand, but I don't know how effective it is?

After Li Gen finished writing, he called Zhao Si and Feng Wu.

Both of them are very smart people, and under Li Gen's guidance, they quickly understood the key links.

Li Gen handed the rice paper to his father.

"Dad, the child has something to discuss with you."

Seeing Li Gen's solemn expression, Li Shimin immediately corrected his attitude.

"Gen'er, what's the matter, but it's okay to say it!"

"Dad, I want to go and see my mother and tell her that I have been admitted to the top prize, so that my mother will be happy and happy......"

Douda's tears rolled down Li Gen's cheeks at this time.

provoked Changle to wipe his tears.

"Brother doesn't cry, brother doesn't cry......"

Li Shimin also burst into tears in an instant!

Gen'er High School Champion!

Li Shimin also only thought of the happiness of the living, and ignored the hidden grief in Li Gen's heart.

"Gen'er, go with you for your father, if Gen'er agrees, let's move your mother's grave over, and save your mother and ...... alone."

Dad's words instantly made Li Gen cry like rain!

"Dad, is this true? Gen'er naturally agrees......"

"It's true, it's not good for my father, this matter has long been good for my father, but it's been delayed!"

"The Great Luo of the Worlds"

Li Shimin's red and swollen eyes were full of guilt.

"Daddy........."
