Hearing Li Yuan's somewhat tasteful words, Li Er is not pursuing Zhang Nan's sin of not coming out to greet him, although Li Er doesn't like the courtiers, but Li Er is still happy to accept Zhang Nan's flattery, after all, Zhang Nan is a talented person in Li Er's eyes, so Zhang Nan is loyal to Li Er, and Li Er will feel that he has an inexplicable sense of happiness.

After all, it is also a matter of pride to be able to conquer a talented person with his own personality charm, no matter what time it is.

"Then today, I will bother my father and the emperor to bring his sons to the academy to go around." Li Er said with a smile.

"Hmph, let's go." After Li Yuan finished speaking, he turned around and walked forward, Li Er hurriedly gave Empress Changsun and Li Lizhen a look, so Li Lizhen ran to Li Yuan's side quickly, and took the initiative to hold Li Yuan's arm, and Empress Changsun also accompanied Li Yuan and followed Li Yuan forward.

Although Li Yuan is very unhappy with his son, Li Yuan is still very satisfied with his daughter-in-law and granddaughter, especially Li Lizhen, which is not only the pearl of Li Er and Empress Changsun, but also Li Yuan's heart.

The group walked forward like this, and when they reached the gate of the academy, Li Yuan pointed to the signs hanging on both sides of the academy and said, "Look at this character, how about it, this is my handwriting." ”

Li Lizhi raised her head, looked at the signs on both sides of the gate of the academy, and read word by word: "The mountains have roads and diligent paths, and the sea of learning is endless." Grandfather Huang, these two sentences are really well written, not only this word, ah no, not only these two sentences are thought-provoking, but with Grandfather Huang, your words are a perfect match. ”

Li Lizhi is really Bingxue smart, knowing that Li Yuan likes to listen to these beautiful words, so he is not stingy to offer his own sycophants.

After listening to his granddaughter's praise, Li Yuan laughed and said, "You, you, I don't know you yet." What you just want to say is that this word is a perfect match with this superb good sentence. ”

Li Li, who was pierced by Li Yuan, smiled shyly. Li Yuan gently nodded on Li Liqin's head.

"Father's words are indeed good, persuading people to move up, persuading people to be studious, not bad. I don't know who made the two sentences, but I guess it must have been done by some great Confucian in the world. Li Er also offered his views in a timely manner.

"Haha, if you praise the minister like this, the emperor will be embarrassed." When everyone heard the voice, they looked for it, only to find that Zhang Nan was walking this way with a smile licking his face.

Zhang Nan walked to the side of the group and saluted Li Yuan, Li Er, Empress Changsun and Li Li in turn. Although Li Chengqian and Li Tai saw Zhang Nan, they had to shout respectfully: "Master Zhang." "But Zhang Nan is not familiar with Li Li after all, so there should still be a number of courtesies.

However, when saluting Li Li, Zhang Nan also took the opportunity to take a closer look at this princess with a thin face, it is undeniable that Li Li and Cui Yue have their own merits, and the beauty is equally divided. Zhang Nan even came up with a terrifying thought, that is, if Li Er was willing to marry Li Li to him, it would be good to be a son-in-law to Comrade Li Er.

But soon Zhang Nan put this unrealistic idea behind him, after all, Zhang Nan doesn't like to be a son to others, and Zhang Nan in later generations is used to being a grandson, and Zhang Nan, who has returned to the Tang Dynasty, will not be like this anymore.

"Qingquan, are you saying that you did these two sentences?" Li Er asked.

"That's inevitable, but this great Confucian in the world can't be deserved, after all, the minister is a traverser, and the emperor praises the minister as a great sage in the world." Zhang Nan said with a shameless look.

Zhang Nan's words amused Li Er and them at once, not only Li Er laughed heartily, but even Empress Eldest Sun and Li Lizhen also covered their mouths and laughed.

Li Er nodded at Zhang Nan in the air, and said with a smile: "You, you, you can't go to heaven with these two sentences of praise for you." ”

"Your Majesty, it's not right for you to say that, but the minister is really deserved, why can't you afford to talk about these two sentences." Zhang Nan said.

Hearing Zhang Nan say this, Li Er nodded, indeed, this sentence is indeed very good, but Li Er can't say it clearly, so he diverted the topic and said: "By the way, I haven't asked you yet, what is going on on your road, why has the journey from Chang'an City to the academy become shorter?" Isn't it a clear spring, you still have the skill of moving mountains and reclamation? ”

Zhang Nan wanted to say that he didn't know how to move mountains and reclaim the sea, but then Zhang Nan thought about it, there is a system, coupled with the development of science and technology, not to mention moving mountains and reclamation, even going to the moon, so Zhang Nan nodded and said: "The minister also knows a little about this art of moving mountains and reclamation, but this time it is not the art of moving mountains and reclamation, the minister just simply built a road." ”

"But why is the journey so short?" Li Er asked a little strangely.

"Your Majesty, think about it yourself, whether the tortuous sheep intestine path is fast, or this straight road is fast, and this road is so smooth, no matter whether it is windy or rainy, there will be no problem." Zhang Nan said.

was reminded by Zhang Nan like this, and Li Er thought of this simple truth.

"Well, I see, but what is this road made of? Why is it so hard, and it is not tolerated by water, and it is not broken when it is forced. Li Er asked a little strangely.

"It's actually made of simple limestone and mud sand." Zhang Nan said.

"It's as simple as that?" Li Er was a little unconvinced. "The official road of the Tang Dynasty is also made of mud, sand and stone, why is it not like this?"

"Eh, what the emperor said, even if this is the most ordinary clay and sand, in the hands of the minister, it can turn waste into treasure, and the minister's hand is called turning decay into magic. As the saying goes, if you want to get rich, you must first build roads, and the minister suggested that the emperor should pave the official roads of our Tang Dynasty with cement, which is a good thing for the benefit of the country and the people. Zhang Nan said.

"Want to be rich? Build a road first? It's kind of interesting, so let's talk about this thing carefully. Li Er obviously heard the word "rich", and his interest immediately came up.

"Areas with backward transportation must be poor, you can admit it." Zhang Nan asked.

Li Er nodded noncommittally.

"Backward transportation has hindered the progress of transforming our resource advantages into economic advantages in Datang, and backward transportation will naturally become a bottleneck for Datang's economic development. Once the transportation is improved, Datang's resource advantages can be quickly transformed into economic advantages, driving local development. Zhang Nan said.
