Zhang Qingqing and his grandfather Tian Khan walked in the palace, looking at the buildings here.

Li Shimin is nearly fifty years old, but his figure is still standing tall.

The words and deeds of this heavenly khan always have the majesty that is quietly revealed, which makes the palace people and guards along the way bow their heads and pay respects.

It's like a paradise that has stopped changing.

Li Shimin stroked his beard and said: "Since Zhenguan has been four years, it has not changed here, and it is still the same. ”

"The outside world is changing, and there should be changes here."

My granddaughter has a very beautiful voice, and I feel very comfortable listening to her.

After stepping down from the position of emperor, Zhang Qingqing no longer had a prejudice against this grandfather.

After releasing his previous suspicions, Li Shimin doted on this granddaughter very much, she was very smart and sensible.

She was different from other children.

For example, children like Li Xiang and Li Shen, they follow the rules and know how to be polite, but these children lack some agility, the courage to not rely on others and dare to question and ask questions.

And Zhang Qingqing's current age, these qualities are even more dazzling in her.

Walking from the Taiji Hall to the Taiye Pool, Zhang Qingqing looked at the scenery in the palace and asked, "Grandfather, if you want to rebuild the palace, this must be a big project." ”

Li Shimin bowed his head and said, "What? Would you like to renovate this place? ”

Zhang Qingqing replied: "When my grandfather passed away, he told me a lot of bad things about the palace, the palace of the Tang Dynasty is the most noble place in the world, and it needs to be changed and become more magnificent." ”

"Papulous?" Li Shimin said with a smile: "Lishan has windows made of glazed glass and greenhouses made of hot spring pools, isn't it magnificent enough?" ”

"Actually, Lishan is not rich at all."

The palace people followed from afar, not daring to disturb this Tian Khan, and they were also very curious about the little girl who was standing next to Tian Khan, wearing a green shirt.

This little girl's conversation looked extraordinary, standing beside Tian Khan without bending down or bowing her head, as if she had a sense of arrogance.

Zhang Qingqing said: "If the renovation of the palace can be handed over to Lishan, Lishan will definitely make this the most prosperous place." ”

"You are really exactly like your father, and you dare to negotiate with me."

"Doesn't my grandfather think that this palace doesn't need to be rebuilt?"

Li Shimin stroked his beard and said: "That's your mistake, the palace doesn't necessarily have to be rich, the emperor needs to set an example, if the emperor is extravagant, the people in the market will be extravagant, this is not good." ”

Zhang Qingqing said: "Then build more plain and grander." ”

If Zhang Yang said such a thing, Li Shimin would definitely refuse, but when this came out of his granddaughter's mouth, it was difficult to refuse.

Li Shimin continued: "Don't you Lishan like to plan for three or five years in advance? ”

Zhang Qingqing nodded and said, "Exactly." ”

"Then come up with a plan for me first, if the plan is feasible, I can let you rebuild, and I think Cheng Qian will agree."

After walking around the palace, I felt that it was not interesting.

Zhang Qingqing walked out of the palace with his grandfather happily.

In the Xingqing Palace, Li Chengqian put a piece of music on the table and said in a low voice: "Look at it, there are people who are slandering now, and let me go to Mount Tai to seal Zen." ”

Cen Wenwen replied: "Now the achievements of the Tang Dynasty are indeed enough to seal Mount Tai. ”

Li Chengqian said with a calm face: "My father didn't say anything about Feng Zen, how dare I?" ”

This emperor is like this, he wants to do his best in everything, he is eager for quick success, but he does not dare to slack off, treats his courtiers harshly, and does not allow half of humanity to act in a face-to-face manner.

Li Chengqian said in a low voice: "How do you see that good prescription?" ”

"Back to Your Majesty." Cen Wenwen saluted and said: "Zhongshu Province has been discussed, the minister has seen it, it is to use silver and gold to stabilize the value of copper coins, few people in the court have come into contact with this kind of knowledge, and the good prescription sent by the small county lord of Lishan is jerky and difficult to understand." ”

"In your opinion, can this cure alleviate the current situation?"

"Yes."

"Well, you must eat this recipe thoroughly."

"Whoa."

The emperor made a decree, and the people of Zhongshu Province began to discuss it all night, because the prescription given by Lishan did not have a complete framework, so the court and China discussed it for a long time.

Until late at night, Xu Jingzong and Cen Wenwen walked out of Chengtianmen.

Cen Wenwen relaxed his back and said with a smile: "I didn't expect that the little county lord of Lishan to be able to come to the Taiji Palace. ”

Xu Jingzong said: "Yes, I used to see her just a little girl, but I didn't expect to grow so tall." ”

Seeing that he still looked a little painful, Xu Jingzong hurriedly said, "Come, let's support each other." ”

Cen Wenwen sighed and said, "Alas, it's okay. ”

The two elderly middle-aged ministers were back to back, their wrists were crossed, Xu Jingzong bent down to support Cen Wenwen's back, and his back and lumbar vertebrae suddenly made a bone clicking sound.

Now it was Cen Wenwen's turn, and he bent down to prop up Xu Jingzong's back.

"Brother Wen, slow down, the old man's back hurts a little."

Cen Wenwen nodded.

Under the moonlight, the two of them relaxed their backs like this, and it took a while to feel more comfortable.

Continuing to walk together, Xu Jingzong suddenly said again: "How is your neck?" ”

Now that his back is more comfortable, Cen Wenwen rubbed his stamina and said: "Oh, the pain of this body, I don't know what year and month it is." ”

Xu Jingzong said: "The old man still has a few chairs at home, and the neck cushion is made by Lishan, and it is not a valuable object to send you some next time." ”

Cen Wenwen nodded, "It's okay." ”

Xu Jingzong said again: "The Lishan Medical Center has come up with a technique of massaging the waist and back, and the old generals in the court have tried it, and it is not bad." ”

Cen Wenwen smiled: "Anyway, it's a rest, you might as well try it." ”

The two walked all the way and chatted all the way.

Outside the Suzaku Gate, they went back to their homes.

When the morning light came out the next day, it was also a rest in the middle of the court.

Many officials breathed a sigh of relief, the current emperor is strict with his courtiers, and this year, everyone is under a lot of pressure.

Since the Han Dynasty, regardless of the Wei, Jin, Southern and Northern Dynasties, it is not uncommon for copper coins to be privately minted and abused, and even sometimes copper coins are not worth much.

So Lishan gave a good prescription.

The prescription of the gold standard and the silver standard is just an idea for the court, and the Marquis of Lishan County writes very vaguely.

The composition of this money system is too complicated, and Zhang Yang feels that as a model worker in science and engineering, it is too difficult to understand this knowledge, so he only writes some superficially.

As for how much the DPRK and China can comprehend, it all depends on themselves.

The next day, Xu Jingzong woke up very early, and as soon as he opened the door of the house, he saw Di Renjie standing in the snow.

"You're back?"

"Yes, the kid is back." Di Renjie smiled and saluted.

Xu Jingzong nodded and let him in, "Have you seen your father?" ”

Di Renjie replied: "Last night, I was at my father's house and told him about the preparations for the imperial examination. ”

Xu Jingzong suddenly came back to his senses and said, "It turns out that you have reached the age where you can participate in the imperial examination." ”

Xu Jingzong's wife walked out quickly, "Renjie, why don't you knock on the door when you come." ”

Di Renjie said again: "Daddy said, Xu Zhongcheng came back late at night after discussing with people in Zhongshu Province last night, and I don't know when you will wake up. ”

Xu Jingzong poured him a bowl of hot water, "Dispel the cold." ”

"Thank you, Zhongcheng."

Xu Jingzong asked again: "I have seen a lot of knowledge from this trip, right?" ”

"Well, the kid went to the Hexi Corridor, I wanted to go to Broken Leaf City, but I didn't go because of the long distance, and then I went to the Jiangnan Territory, went to sea, saw the vast sea, the steam engine ship is very suitable, there will definitely be more people going to the far sea in the future, and I also went to Liaodong......"

Di Renjie told all the travels in the past two years, Xu Jingzong listened carefully, and when he heard the situation of land annexation in the south of the Yangtze River, his face became a little dignified.

But when he heard him talk about Jin Chunqiu's ambition and his plan to kill the Japanese slaves, Xu Jingzong's face was a little more pertinent.

Xu Jingzong said in a low voice: "The rule of the Tang Dynasty is very simple, if the Waiyi can obediently bow down and be a vassal, it is naturally possible, but if they want to make a mess, just like Xue Yantuo, it will be destroyed, and it will be nothing for the Tang Dynasty." ”

These are all digressions, Xu Jingzong said: "What are you going to do after that?" ”

Di Renjie replied: "The kid plans to study hard in retreat for the past few days to cope with the imperial examination in the coming year, otherwise Liu Dewei, the secretary of the Criminal Department, probably won't let the kid go." ”

Xu Jingzong said again: "You don't have to be afraid of that Liu Dewei. ”

"Boy, I don't know what's wrong? I always felt that I would be beaten to death by this person. ”

After talking a lot to Xu Jingzong, Di Renjie left here to visit Zhang Khan Zhi.

In the past two years, Zhang Cambodia, a bachelor of Hongwen Hall, has also gained some fame, especially this guy scolded the people in the Shi clan for being pigs and dogs.

When Di Renjie arrived at the Hongwen Pavilion, Zhang Cambodia was still talking to the students here as always, and he couldn't help but feel melancholy, he was still the same after two years.

Walking into the Hongwen Pavilion, Di Renjie needs to consult the files here to understand the various national policies of the Tang Dynasty.

Recently, the DPRK and China have begun to rectify the copper coin currency, and they want to anchor the money to gold and silver, so as to control the barbaric development of copper coins.

In the past, the Heavenly Khan controlled the soldiers and horses of the world and expanded the territory.

The current emperor wants to control the world's money and grain taxes to stabilize the economic development of the Tang Dynasty.

Today, there are also many Lishan scrolls in Hongwenkan, and the court and the central government slowly began to recognize Lisan's scholarship.

Especially this time, the gold standard came out, which set off a storm in the government and the opposition.

And in this storm, how many people who can't keep up with the changes of the times will be eliminated.

Lishan Academic has always believed in learning and living to old age.

Now the same is true in the court, if the officials in the court stop studying and do not keep up with the current national policy, it will also lead to backward ways of thinking, and they will be eliminated in the monthly examinations.

When I left Chang'an City, it was fine.

In the two years since he left, when Di Renjie came back again, he found that there had been earth-shaking changes here.

The various national policies formulated by Li Chengqian are dizzying just by looking at them.

Di Renjie began a life of hard reading again, and every time he read a book in Hongwen Hall, his hands and feet would be cold.

This kind of hard work passed quickly, and heaven and earth changed day and night.

Unconsciously passed the New Year, and it was a new year for Datang.

This year, the DPRK announced a piece of news that fell like a boulder on a calm lake.

The government and the opposition began to discuss again.

This news is precisely because Lishan gave the DPRK a good prescription to solve the dilemma, and the DPRK and China want to open a money bank.

This money store is a newly established official residence, that is, the emperor's hands and feet used to control the world's money and grain taxes.

The emperor has centralized power again and again, from the supervision system to the current opening of money banks.

The centralization of power in Li Chengqian's hands has reached a point where it is beyond limit.

The new emperor had only been on the throne for a year, and his centralization of power had reached its peak, something that had never been done by the Heavenly Khan before.

It is also something that the emperors of all dynasties did not dare to do.

Li Chengqian stood at the pinnacle of imperial power, and his power also reached the highest level since the founding of the Tang Dynasty, surpassing the Wei, Jin, Southern and Northern Dynasties, and even the former Sui Dynasty.

With the development of production and trade in Guanzhong becoming more and more rapid, it is inevitable that Datang will have a money crisis.

For Lishan, this kind of thing is bound to happen, but it is only a matter of time sooner or later.

As early as the thirteenth year of Zhenguan, Lishan began to hoard silver and gold, and used a lot of copper coins.

And Lishan has always maintained the richest position in the guan.

The counties in Guanzhong also smelled the smell early, and they have reduced the outflow of silver cakes since last year, and except for bulk goods, they can not use silver cakes.

Before Datang's money system has a perfect structure, this depreciation of copper coins will continue.

This is a necessary process, in the past, a bucket of rice only cost four yuan, now a bucket of rice has risen to eight yuan.

Prices began to rise, and copper coins began to depreciate.

As far as the DPRK and China are concerned, their time is very tight, and they will definitely come up with a practical charter for the opening of the DPRK next year.

This is also the reason why Li Chengqian was eager to announce the news of the opening of the money bank during the period of retirement.

Compared with the Guanzhong of Lishan in the DPRK, the response is much calmer.

The embankment of the Yellow River north of Tongguan, Pei Yan can't remember how many times he has visited the Yellow River.

It is urgent to build dams and carry out the project of harnessing water and sand flushing.

Governing the Yellow River is the top priority of Taifu Temple, and Pei Yan took over such a major fortification as soon as he served as Shaoqing of Taifu Temple.

If this fortification can be successful, the control of the Yellow River will be able to achieve great feats.

Normally, a dam is a wall, a flat wall, and many people think that a dam should be like this.

But Pei Yan's design of the dam is tortuous, and this tortuous dam is more suitable for the treatment of the Yellow River.

Ordinary dams, without reducing the flow of water, can control the water level is not too high, and to increase the flow rate of the water flow, which is a dam on both sides of the water level change, reduce the flow area of water, resulting in a decrease in kinetic energy and an increase in potential energy, so as to avoid causing flooding.

This is a zigzag zigzag dam that has been tried by Lishan for many years, and it is a zigzag zigzag dam to keep the water level upstream and control the flow of water downstream.
