After getting his brother's letter, Li Yuanjia did not rush to open it.

Speaking seriously, he and Li Lingkui haven't seen each other for a long, long time. Since the titles and fiefs of the princes of the Tang Dynasty were greatly adjusted, he returned to Chang'an, and after his younger brother went to Luzhou, he could only rely on letters to keep in touch.

Fortunately, blood is thicker than water, and in this world, they are closest to each other...... Oh yes, for Li Yuanjia, now another Fang Fengzhu has been added.

For his younger brother, Li Yuanjia is still quite satisfied.

Good at learning, good at cursive, official calligraphy, Tongyin rhythm, and the breath of literary and artistic youth all over the body! And more importantly, that kid has a good temper, and he is as low-key as Li Yuanjia on weekdays, and he can't see the arrogance of the royal family at all!

Of course, this may also have to do with her mother, Yuwen Zhaoyi...... Or it has something to do with the way His Majesty Li Shimin ascends to the throne today. Anyway, since Li Shimin and the other two fought for the throne back then, the two brothers began to receive the education of "being a man with their tails between their legs", and it seems that there is nothing strange about having a good temper and acting in a low-key manner.

So don't look at being a traverser, Li Yuanjia has a very close relationship with this younger brother.

And......

Although he left Luzhou City, Li Yuanjia left a lot of things in that place, some of which were hardware facilities, which needed to be maintained by his younger brother after they were built, such as sewer systems, public toilets and garbage cans, etc., and some were some "research" that needed the endorsement of Li Lingkui, the supreme governor of Luzhou, so that they could continue.

So every month a letter goes over and a letter comes back, and the thunder can't move.

However, the current Li Yuanjia will not be as anxious as before, and will accompany his wife and children first...... Ahem, someone else's child...... ate a meal together, and then taught two math lessons to Yuwen Shutara in the study, and then waved his hand and smiled: "Okay, there is still some time until noon, let's go play!" ”

"Oh......"

After listening to his words, the little girl immediately cheered.

Rushing up from the small stool with a roar, Yuwen Shutara almost couldn't wait to shout: "Ink painting, let's go, let's play with the big landlord...... Hurry up! ”

"Yes, miss...... You're slowing down......"

With the voice of Mo Hua being a little anxious, the two disappeared from Li Yuanjia's study.

Then as a teacher, he shook his head speechlessly and sighed: "Sure enough, no matter how interesting the math problem is...... That's math too! It is a bit fanciful to expect to use this kind of thing to attract a child's attention for a long time. ”

After smiling bitterly, Li Yuanjia's expression quickly became relieved: "But it's already good, at least this girl's talent is okay, and she learns quite quickly...... Unfortunately, math can be taught, punctuation can be used by her, but science has to wait for me to figure out the source...... And pinyin, this thing is too troublesome to do! ”

Rubbing his nose, Li Yuanjia had a headache.

Pinyin is really a powerful tool for teaching children to read and write, but there are a lot of things that have been considered before, so Li Yuanjia has not taken it out.

But now because of the "disciple" of Yuwen Shudora, he feels that it is time for Pinyin to come out and show his face.

Merely......

When he really thought about it seriously, Li Yuanjia found that it was really nonsense to copy the pinyin scheme!

In Chang'an in the sixth century AD, the difference between pronunciation and the future is tens of millions of miles?

If you want to figure it out......

Mmmm, at least ten days and half a month, right?

While having a headache and one more thing to do, Li Yuanjia casually opened his brother's letter, and then read it carefully.

Then, his brows were furrowed at first, and he quickly stretched out randomly, and a smile appeared on the corner of his mouth: "Hehe, this kid is quite serious about doing things...... It seems that they know that I am in a hurry to get results, so I sent someone to speed up the collection of this data? ”

For his younger brother's "diligence", Li Yuanjia couldn't be more satisfied.

"Gotcha! Get! ”

At this moment, there was a sudden knock on the door of the study.

"Come in!"

"King, is today's class over?"

"Hehe, it's just over."

After seeing the comer, Li Yuanjia's eyes lit up, and he hurriedly beckoned: "Fengzhu, come and take a look at this letter......"

"Letter? Whose? ”

"Hehe, who else could it be? Of course it's King Xu! ”

"This ......"

Walking to Li Yuanjia's side, Fang Fengzhu frowned slightly: "King, what important things did King Xu's letter say?" It can't be something wrong with what was sent last time, right? ”

When he said this, Fang Fengzhu was a little apprehensive in his heart.

Of course she understands that the relationship between the two brothers is good, but her husband sends people to Luzhou every once in a while, and everyone has to send at least one truckload of goods every time...... But whenever there is something good in the Han Palace, King Xu may not be the first outsider to use it, but it will never be lacking!

So since taking over this matter, Fang Fengzhu has been very careful.

"No, it's okay with those."

After hesitating for a moment, Li Yuanjia took a deep breath and said, "Forget it, don't ask, just look at the content of the letter!" ”

As he spoke, Li Yuanjia handed over the letter.

Fang Fengzhu didn't know how much he had read the content of his and his brother's letters, and there was nothing taboo in this letter...... In other words, the things inside were originally for Fang Fengzhu to see!

And took the letter with a puzzled face, but after reading it for a while, Fang Fengzhu's face immediately changed greatly!

"This ...... This ......"

After reading the entire letter, Fang Fengzhu swallowed several mouthfuls of spit, and asked in a trembling voice: "King, what is said in this letter...... It's all true? ”

"Well, can this still be fake?"

Nodding, Li Yuanjia replied very calmly.

"But...... But ......"

Looking at the princess's unspeakable appearance, Li Yuanjia smiled slightly, and then said: "Of course, Lingkui's statistics are still relatively small, maybe the convincing power is not very strong, but after all, there is such a possibility, right?" ”

“…… Be. ”

It's been more than a year since she married into the Han Wangfu, and of course Fang Fengzhu can hear new words such as statistics and data, but because of this, her mood at this time is becoming more and more complicated.

This...... How is that possible?

The buzzing in his head turned into a pot of porridge, and Fang Fengzhu didn't know what to say for a while.

Li Yuanjia understood her mood at this time, after all, the content of the letter was ...... How so? In this era, it is indeed a bit too shocking.

So after pondering for a while, Li Yuanjia held Fang Fengzhu's little hand and said softly: "So we still have to be cautious about this matter, and we must not be in a hurry......
