The ancients were not stupid, the mountains were cut bald, and when it rained, the mountains collapsed and soil erosion was also seen.

Although the understanding is not very profound, it is still possible to distinguish the general good from the bad.

As we all know, the main restrictions on the use of coal were the difficulty of mining and transportation.

In this era when going out for ten miles is even a long journey, it is a real difficult thing to transport materials on a large scale.

For a similar matter, you can refer to the transportation of grain through the Grand Canal.

It was not until the appearance of Li Yunze that he brought advanced mining technology and tools to build a railway line to the coal capital.

In the past, those things that seemed impossible to do, or barely done, could only end up like Yang Guang, and the big projects were finally solved in the real sense at this moment.

The coal mines on the Shengzhou side naturally belong to the imperial court, and Li Yunze's mining technology and equipment were sold for a sum of money.

But the problem is that the imperial court has mined a large amount of coal in the local area, but the local government can't digest it at all.

Even if it is sold to all parts of the surrounding area, the shipment volume is only a drop in the bucket.

The real consumption is still in Chang'an City and Guanzhong Plain in the south.

More than 1,000 miles of coal was transported, and whoever transported it lost as pants, but only by using trains.

The freight charged by Li Yunze very simply took away most of the profits of the mine.

There is no solution to this problem, because the demand for coal in Guanzhong is huge.

The people of Guanzhong are accustomed to honeycomb coal and stoves, and a few cheap pieces of coal can be used for a whole day.

It can be used to boil valuable hot water and to maintain the temperature in the room.

Moreover, all the budding industries also need to use coal, especially Li Er's forced demand that the iron factory must be built around Chang'an City, and even simply stipulated that it should be near Longshouyuan.

Even if Li Yunze repeatedly persuaded him, he said that it was best to build the iron factory next to the coal and iron mine, and the iron factory was very polluting, and it was built next to the imperial palace.

It's a pity that Li Er was unmoved, saying that such an important weapon of the country must be under his nose.

What else can Li Yunze say, he can only run away overnight to live in Zhuangzi in Lantian County, and he will never go to Chang'an City if he has nothing to do on weekdays.

In addition to these uses, large-scale construction of hardened roads also requires the use of large amounts of coal gangue and cinder.

The roads in Chang'an City are okay, especially Suzaku Street, which can be called the pinnacle of roads.

But the problem is that Suzaku Street is a face-saving project that concentrates countless manpower and material resources, and there is only one Suzaku Street.

In other places, the roads are full of potholes and mud, which is a common thing.

This is still Chang'an City, the capital of the Tang Dynasty.

Once out of Chang'an City, in addition to the excellent road to Lijiazhuang, the roads in other places are 'covered in soil on sunny days, mud on rainy days', and even when it rains, potholes on the road surface can drown people.

It used to be the same all day, and naturally no one thought there was anything wrong.

But since the appearance of the hardened road from Lijiazhuang to Chang'an City, it is natural to have ideas.

Since the successful completion of the river dredging project in Chang'an City, Li Er has been thinking about road repair.

Until the opening of the railway, the supply of building materials for large-scale road construction was guaranteed, and the large-scale construction of hardened roads could not wait to begin.

When the train slowly stopped at the majestic and magnificent Chang'an Railway Station, the tribal nobles who were invited to come were all staggering and walked off the train with dull eyes.

It's not that Li Er fed them something they shouldn't eat, but that the shock and excitement brought by riding a train like an unprecedented steel giant were too strong to accept physically and mentally for a while.

Especially the train that I got on yesterday after breakfast, and the sunset in the distance has not yet set today, so I have already arrived in Chang'an City?!

The unprecedented experience has brought them a huge impact, and they are naturally in a trance, and they can't adjust it for a while.

When they got out of the station and came to the hardened road to Chang'an City, they stepped on the wide road that was as solid as a rock but smooth as a mirror, leading to the city gate, and looked at the bright oil lamps lit on both sides, only feeling as if they had come to a fairyland.

"Hasn't he walked through it and seen it all?" Li Yunze tugged on Li Tao's sleeve and motioned to Fu Yun Khan, who was also distraught not far away, "Why do you still look like you haven't seen the world?" ”

When Li Tao took the train for the first time, he behaved similarly.

Of course, at this time, it is natural to laugh and laugh, "When he was in Shengzhou, he saw the Tuyuhun people working in the mines. ”

"Oh~~~"

As soon as he said this, Li Yunze immediately understood.

As a khan, not to mention the destruction of the country due to his own defeat, his former people were all sent to the mines as coolies, this kind of mental stimulation is indeed too strong.

Li Yunze looked at Fu Yun Khan with interest, and asked Li Tao with a smile, "Do you want to make a bet?" ”

Li Tao is not popular among the noble group of the Tang Dynasty, because this guy is too insidious and likes to use all kinds of intrigues and tricks.

In the past, everyone avoided him, like Li Yunze, who had no fear, and there were very few sincerity.

Hearing this, Li Tao also became interested, "What bet?" ”

"Just bet when he can't stand it anymore and will kill himself."

"Haha~~~" Li Tao stroked his beard and smiled, "However, the old man bets that he will commit suicide within a year." ”

Li Yunze simply shook his head: "I bet that he will commit suicide after participating in the Daming Palace ceremony." ”

Li Tao came back to his senses reluctantly, and it was a mistake to extend the time out of caution. This kind of time should be as short as possible, because there is room for this kind of thing.

Li Tao, who made a mistake in the secret way, did not change his face with a look on his face, "What about the bet?" ”

"If I lose." Li Yunze laughed heartily: "That picture of the female historian will be given to you." ”

Hearing this, Li Tao of the old Yin coin couldn't hold back, and immediately changed color, "You are here for "Luo Shen Futu", you calculate the old man?" ”

Li Yunze swept his eyes over: "Want to regret it?" ”

Li Tao really wanted to regret it, but unfortunately the eyes of everyone around him made him feel like a man.

It's true that he is an old Yin coin, but the old Yin coin also has to be faced.

If you do this kind of thing in front of so many people, don't go out in the future, and continue to mix in the noble circle without face.

In the Tang world, there are not many things that can attract Li Yunze's interest, and those treasures that have long been lost in later generations are what he wants.

Of course, the same thing in a different world, he only needs it once.

"Luo Shen Futu" is a painting by Gu Kaizhi of the Eastern Jin Dynasty, which is colored on silk.

It is not a single painting, but a long scroll of paintings that resembles a comic strip composed of multiple storylines.

It's the same kind of comic books that used to be popular, except that each one is big and beautiful.

Since it is a comic book, it has a story, and its whole volume is divided into three parts, which depicts the sincere and pure love story of Cao Zhi and Luo Shen in a detailed and layered manner.

This is a classic love comic book.

In Li Tao's home, there is a page, or an illustration of "Luo Shen Futu".

There is no doubt that Li Tao regards it as a treasure, but now he is being targeted by Li Yunze, and his mood is really conceivable.

"Don't worry."

Li Yunze, who was smiling, simply said, "Even if I win, I will give you a gift as compensation." ”

Li Tao gritted his teeth: "Don't use means. ”

Li Yunze's eyes looked at him as if he was looking at the sand withering, what kind of bet do I have with you without means!

The nobles who watched this scene all the way looked at Fu Yun Khan with pity.

When he lost the battle, he simply committed suicide, why bother to see why Datang was so powerful (Fu Yun Khan's own reason for being captured and surrendered) is now being targeted by two foxes, and I don't know how miserable it is.

Li Er, who was full of ambition, received a bet between Li Yunze and Li Tao after returning to the palace.

And Li Er's first reaction was not to cry out for Fu Yun Khan, but to immediately ask the inner servant, "There are a few volumes of "Luo Shen Futu" in my inner library, he doesn't know, right?" ”

Li Er was also afraid, he was afraid that Li Yunze would make conditions that he couldn't refuse and take away his baby.

It's like losing the Lanting collection at the beginning.

It was really to check the door lock of the inner library overnight, for fear that Li Yunze would be worried about it again.

The frightened Li Er had nightmares for several nights in a row, and in his dream he saw Li Yunze snatching his treasure, which was called miserable.

In scientific terms, this is called psychological trauma leading to dream disorders.

In layman's terms, Li Er, who has lost the preface of the Lanting Collection, has a psychological shadow.

Empress Changsun was very distressed, and even specially invited Wei Chi Jingde and Qin Qiong to guard the door to prevent the dream demon from disturbing the emperor.

When the news reached Li Yunze, he directly sent someone to send sleeping pills.

The emperor took medicine, which was really extremely cautious, and he had to go through many testing procedures, and there was also a special drug tester to test the medicine and so on.

But the medicine sent by Li Yunze, Li Er did not hesitate at all, and ate it directly with water.

Sure enough, Li Er slept extremely sweetly this night.

After waking up the next morning, he immediately asked Qin Qiong and Yu Chi Jingde, who had dark circles, to hurry home to rest.

Li Er, who wants to be a Ming Jun, is indeed deeply troubled by insomnia.

After all, Dusk Jun only needs to find secrets at night, but Mingjun has to deal with all things in the world in addition to searching for secrets.

Rao is Li Er is strong and has been on the battlefield, but he still has frequent insomnia.

Li Er, who took the sleeping pills given by Li Yunze and had a good night's sleep, received good news on the same day.

Hou Junji, after a long journey, finally arrived at the capital of Gaochang Kingdom.

I didn't expect that the Tang army would cross thousands of miles to fight their Gaochang Kingdom, and they were caught off guard and conquered the national capital in a battle, and even the king was arrested.

The famous Gao Changguo died directly.

Li Er, who was in a good mood, looked up to the sky and smiled, and immediately ordered the Daming Palace to be opened, and a grand celebration was held in the Daming Palace!
