Zhang Nan listened to Comrade Lao Li's emotion while driving, of course, Zhang Nan did not stand up and tell them the truth, you must know that the coal used for thermal power generation in an urban area alone is more than the coal output of Datang in a year, Zhang Nan is afraid that after saying it, it will be too big a blow to Lao Li.

Lao Li Ke is a proud person, if he knew that he was so much more advanced than Datang here, then Lao Li would not go back until he finished learning the scriptures here.

"Is that a steamship?" Lao Li pointed with his hand, Zhang Nan glanced at the river with his spare eyes, and saw a ferry about the size of a steam ship in the Tang Dynasty traveling on the river.

"It's not a steamboat, it's diesel, and these ships are powered by diesel." Zhang Nan explained.

"And that's better than our steamship?" Lao Li is naturally fearless who doesn't know, but Zhang Nan can't do it, after listening to Lao Li's question, Zhang Nan is thinking about how to answer Lao Li's question in his heart, which can not only not hurt Lao Li's self-esteem, but also explain to Lao Li how big this gap is.

But Zhang Nan thought about it for a long time, and finally came to the conclusion that there was no such way, so Zhang Nan could only tell Lao Li the truth.

"Mr. Li, there is really no comparison between the two, this belongs to the industry across the era of technology, simply put, the emergence of the steam engine represents the industry into the steam age, but this ferry uses an internal combustion engine, which is epoch-making." Zhang Nan didn't elaborate, but according to Comrade Lao Li's ingenuity, Zhang Nan believed that Lao Li Tie would definitely be able to understand what this meant.

"Is it like the relationship between Sui and Tang?" Lao Li gave an example that was not very appropriate.

"It's about the same, but it's a long way off." As soon as Zhang Nan said this, Lao Li stopped asking.

"Guanyin, have you noticed that the people here are very different from the people over there?" Zhang Nan's speed was not very fast, so that Lao Li could see more scenery on the road.

So Lao Li could see the satisfied smiles on the faces of the people who came out for a walk after dinner.

"I really haven't seen this." Empress Eldest Sun also said truthfully.

"Mowgli, do you see that?" Lao Li asked the eldest grandson Wuji again, who was sticking his face to the window at the same time.

"This ......" In fact, the eldest grandson Wuji didn't see it.

"The Emperor...... Ah no, Mr. Li, I actually see something. It was Cheng Yanjin who spoke, and as soon as Cheng Yanjin said this, the rest of the people looked at Cheng Yanjin with disbelief.

"What are you doing, what, it's not your right to look at people like this, besides, I'm very accurate for a rough person to observe people." Cheng bites the golden road.

"Then you can talk about it." Comrade Li Er raised his hand and motioned for Cheng to bite the gold but began to speak.

All I saw on these people's faces was the word "contentment." Cheng bites Jin Dao.

"Satisfied?" After Fang Xuanling and Du Ruhui heard Cheng Yanjin's evaluation, they chewed the word in their mouths, and then leaned their faces out of the window to look.

"Yes, I think so too, it seems that the people here always have a feeling of satisfaction, which is very strange, this feeling has never been given to me by the people of any other place." Comrade Lao Li did not know exactly what the reason was.

"Your Majesty, isn't it just four words? Sit under one’s own vine and fig tree. Zhang Nan gave his own answer while driving.

Hearing Zhang Nan's answer, Li Er couldn't help but think about it in his heart, and after a long time, Lao Li opened his mouth and said: "Qingquan is right, that is, live and work in peace and contentment, this is a feeling of peace and prosperity for me." ”

Are the people of Chang'an City satisfied? Naturally, they are satisfied, when they are full, there is nothing more satisfying than this, ordinary people, after eating, can chat in front of the house or in a crowded place, and talk about the mountains, it is really satisfying, although now the people of Datang will not be bothered by hunger.

But in their hearts, they are all afraid, they are afraid that such a well-fed life will be gone, they are also afraid of war, they are afraid of everything, so they will not give Comrade Li a feeling of satisfaction.

It takes several generations or even more for such a mentality to be transformed, and the mentality and self-confidence of a country's citizens cannot be changed in a short period of time.

No matter how holy Comrade Lao Li is, he has to admit that the happiness of the people in the early Tang Dynasty is naturally not as good as that of the people in the Tang Dynasty, and the time that has been experienced in this has already exceeded three generations.

"When will the people of Chang'an City be like here, and they can take their families out for a walk and see the scenery after dinner, then my life will be worth it."

Lao Li, as a Ming Jun, of course, put Jiangshan Sheji in his heart.

"Your Majesty, this meal has to be eaten one bite at a time, the development of our Datang is fast enough, if it is faster, there will be problems, and the rest of the things can only be handed over to time, besides, why should we compare with here? Your Majesty, you also know that this is a place that does not exist for Datang at all. ”

As soon as Zhang Nan said this, Lao Li also nodded, indeed, the place that Zhang Nan brought him to here does not exist for Datang at all, and it is meaningless to compare it with something that does not exist.

"As long as we can ensure that Datang can always be more advanced than those countries on its own territory, and will always have higher technology and culture than those countries, then Datang will eventually arrive here one day." Zhang Nan said.

"Huh, yes, Qingquan is right, it's that I'm thinking too much, it's just that I saw this peaceful and prosperous world, and I can't help but be jealous in my heart, and it's also for me The people of Datang are jealous, when will my Datang have such a situation, hey, I may not be able to see it." When Lao Li said this, he couldn't help but sigh.

He is in his forties this year, and according to Datang's age, he has already begun to slowly enter the ranks of the elderly. After all, Lao Li only lived to be fifty-one years old in his life, which made Lao Li can't help but feel a sense of sadness for his life.

"Your Majesty, we came here to be happy, if you are not in the mood, it will be a failure for the minister to bring you over." Zhang Nan saw Lao Li's emotional life, and he could only persuade him.
