Li Yuzhen said: "This is an accident. ”

Her voice was calm and her expression was calm, as if unaffected by the sudden explosion of the boiler.

When the people who knelt down heard this, their bodies were soft, and they breathed a sigh of relief in their hearts, listening to the prince's meaning, since it was an accident, they would not be blamed heavily?

"Get up. Forgive you no sin. ”

Her tone was gentle, and she really didn't hear the blame.

The way of the emperor, when to be majestic, when to forgive, and appeased, Li Yuzhen is very clear about this.

When everyone heard the amnesty, they kowtowed, "Wait for the grace of His Royal Highness the Crown Prince for not sinning." ”

Yuan Zheng thanked and said: "Your Highness is merciful, thank Your Highness for your kindness." ”

This is to thank the prince for saving the furnace workers and sheltering a number of subordinates.

"Thank Your Royal Highness Prince for your kindness." The class orders and others kowtowed together, especially the dozen or so furnace workers who were rescued and the technicians and technicians close to the boiler were even more grateful, and they were sincere.

After thanking him and getting up, the courtyard was accompanied by the guards to hug Li Yuzhen and left the machine workshop, went to the public room to drink tea and talk, and left the class order and the project team to clean up the explosion site, and the important thing was to check the cause of the explosion.

Li Yuzhen listened carefully, and did not express his opinions lightly, mostly words of encouragement, which made the Yuanzheng's nervous mood relaxed, and secretly said in his heart: Although the prince is dignified, he is not a difficult lord to serve.

About three quarters of an hour later, the order came in to report that the cause of the boiler explosion had been found, because the air pressure was too high for the cylinder to withstand the pressure.

Li Yuzhen listened carefully and asked, "In the previous test, was there an explosion?" ”

Sweat broke out on the head.

He replied: "Returning to Your Highness, the project team successfully developed the No. B steam engine five years ago, because the pressure is relatively low, so it is relatively safe, and there has been no explosion in the test and use; However, the defect is that the power is relatively small, and after it is used in the coal shaft, the Mining and Metallurgical Department reflects that the depth of water intake cannot exceed two zhang, and the coal mining shaft is generally more than ten zhang deep, so the water lifter can only be installed underground for use, and then pumped out in sections, which increases the danger and difficulty. Therefore, in accordance with the requirements of the Mining and Metallurgical Administration, the project team developed a steam ...... with higher power."

"But, however, high temperature and high pressure bring with it the danger of explosion. In the previous test, there was also an explosion accident, and after adding the safety valve three months ago, the explosion risk was a little smaller, but "the order stammered," still ...... Unstable dìng, No. A steam engine has not yet succeeded, and the project team is still improving. ”

He burst into tears in his heart, who knew that His Royal Highness the new crown prince would suddenly come to inspect the latest progress of the project!

The project team is all technical bumps, there is no cunning heart, I heard the order from above that the prince is coming to inspect the latest progress, so I honestly moved out the No. A steam engine that is still being improved, and I didn't expect to use the more stable No. B machine. Today, the furnace workers were too nervous, they didn't have a good grasp of the proportions, the coal was added too quickly, and the air pressure rose too quickly, which caused an explosion - although the technician who guarded the barometer found that the air pressure rose too fast, but it was too late to warn.

But the order concealed this truth, and I felt that I couldn't care too much about the fault of the furnace worker, it was really the prince's prestige that was too heavy, and standing there with a faint look made people sweat nervously, not to mention the humble furnace worker, even if he stood beside the prince, he didn't dare to go out of the atmosphere. What's more, the prince has already forgiven his sins, and they can deal with the mistakes of the furnace workers internally, so don't make any more extraneous branches.

With Li Yuzhen's keen hearing, of course, she heard a technician running under the boiler before the explosion to order the furnace worker to "withdraw the coal", but she did not want to pursue this. This is a trivial matter, not the fault of the superiors.

She was concerned about the progress of the steam engine project, and as for the mistakes in operation, it was not her concern.

"The development of the steam power project is very meaningful," she told the academy and the order, "and it will play a vital role in the development of all aspects of the empire." You have to keep developing and don't be afraid of failure. A momentary failure is nothing, accumulate experience, learn lessons, and you will do better. I look forward to seeing you better next time. ”

"Your Highness!" The class commander only felt that his spirit was back, and he said with an uplifted expression, "Yes, Your Highness." The ministers will definitely overcome the difficulties and produce results. ”

Leaving the steam engine project team, Li Yuzhen, accompanied by the institute, went to several other power research and development workshops of the Fourth Department, or put forward opinions or give encouragement, until the second or third quarter of Youzheng, when the sky was about to dark, he did not leave the machine research department.

Her inspection of the Machine Research Agency this time was not a sudden whim, but because power research and development was too important for the development of the Tang Empire.

As far as the mining industry is concerned, the metal mines and coal mining of the empire have developed on a large scale after more than 100 years of development, and various mining machinery has been continuously developed in response to demand, but power has always been a problem, and it is difficult to meet the requirements of mining by manpower and animal power alone.

For example, coal mining, because underground mining involves groundwater, an extremely dangerous and difficult operation is to remove groundwater from the mine, and the coal mine pit has abundant and cheap coal as fuel, so the Machine Research Agency came up with the idea of "using fire power to lift water" and replacing manpower and animal power as the power, and there is a project of steam power.

Li Yuzhen looked far away.

If the research and development of steam power is successful, it will not only have a great role in promoting mining and mining, but also can be widely used in large-scale machining, so that the efficiency of various military machinery, construction machinery, and workshop machinery will be greatly improved, and it can also promote the emergence of larger and more advanced machinery......

In such a virtuous circle, the industrial technology of the empire can be developed greater, and correspondingly, the economic growth rate will be faster, and as a result, the development of all aspects will be faster.

Datang is already very strong, whether it is national strength, military, technology, culture, economy, land, population, and even martial arts prosperity, it is the absolute first in the world, leading the countries; However, this is not enough, for the Apocalypse Project, Datang is not strong enough.

Li Yuzhen knew that the Emperor Taishang chose her as the heir, and many families chose to be loyal to her, because he believed that she could make the Tang Dynasty faster and stronger.

She turned her head to look at the sunset on the horizon, bright red and gorgeous, and a fiery passion surged in her heart, which was the vitality of youth, the self-confidence, and the heroism of moving forward.

He raised the whip in his hand, "snapped" it in the air, and shouted, "Drive!" ”

The sweaty BMW hissed excitedly, and rushed out with all his strength, causing a group of guards behind him to urgently shout "Your Highness", and flew away with whips.

Li Yuzhen laughed.

The two Tiance generals who were secretly guarding smiled slightly, and said in their hearts: Young people, they are energetic.

The Apocalypse Project also needs such a young monarch to have the courage to forge ahead.

Li Yuzhen galloped for a while, and then slowed down his horse, after all, the speed of the sweaty BMW was not comparable to the guard's horse. Galloping back to Daming Palace, entering Danfeng Square, I saw that an attendant beside the Emperor was waiting outside the Danfeng Gate, and came forward to worship, saying that the Emperor Taishang invited her to go to Ningshou Palace after she returned.

Ningshou Palace is the original east inner garden of Daming Palace, located on the southeast side of the outermost part of the palace city, and it is entered from the Yanzheng Gate. Li Yuzhen sent the guards into the palace to tell the emperor that he had gone to Ningshou Palace, and then turned his horse's head and led the crowd to Yanzheng Gate.

……

Li Yuzhen went to Ningshou Palace and first accompanied the Emperor Taishang for dinner. After the grandparents and grandchildren ate and walked, they went to the East Warm Pavilion of Ningshou Hall to talk.

This is the place where the emperor reads and writes every day, there is no burning dragon tonight, only a charcoal tripod is set up, the indoor temperature is suitable, neither hot nor cold. The emperor only wore a straight jacket with a crane and a hat, which looked very leisurely.

When taking a walk after dinner before, Li Yuzhen had already briefly told his grandfather that he would inspect the fire in the morning. guns, and the situation of the inspection of the machine research agency in the afternoon.

The emperor sat on a circle chair covered with brocade cushions, picked up a piece of music on the bookcase and handed it to Qin You, the head of the chamberlain, and said: "In the morning, you sent someone over to say that you were going to the Machine Research Department today, and I remembered Su Shaowei's proposal - it was already ten years ago, and Su Shaowei was transferred from the local area to the Ministry of Industry Transportation Department Wailang (deputy director), and soon after that, a proposal was put forward because the time was not ripe, so it was temporarily shelved. ”

Of course Li Yuzhen knows Su Shaowei, when she shot as the right servant of the director of Qin Guogong, the Ministry of Industry was one of the six departments in charge of the right servant, Su Shaowei was the right deputy chief of the Ministry of Industry and the right secretary of the Ministry of Industry, and she paid a little more attention to Su Shaowei, in addition to her excellent ability, but also because she was the partner of her eldest aunt Princess Anfu - now the eldest princess of Anfu: although Datang did not officially pass the law on same-sex marriage, same-sex couples were already a public and tacitly acquiesced fact in Datang, and the emperor's grandfather did not object to the two being together, then this Su Youqing is equivalent to her "eldest uncle". What's more, this official with modest character, introverted talent, honest and practical, daring to innovate, and full of pioneering power is exactly what Li Yuzhen needs.

She opened the book from ten years ago and looked at it.

Suddenly, she raised her eyebrows, admiring Su Shaowei's bold ideas.

It's a vision for a railroad.

“…… The railroad carts and cargo handling railcars laid and used in mines and ports have fully confirmed the advantages of railroad carriages in terms of speed and carrying capacity in transportation. If the imperial court lays a railroad in an all-round way, with Kyoto Chang'an as the core, and runs through the north and south and east and west of the empire, the distance between the north and the south and the east and west will be greatly reduced, and the great changes in logistics, commerce and personnel transportation will be promoted, and the technical and cultural exchanges will also be greatly promoted, which will surely lead to the progress of the empire in all aspects. ”

When Li Yuzhen saw this, the first thing he thought of was military convenience.

In that year, Gaozong built the Quartet Military Road, so that the Tang Dynasty army and grain and grass were transported quickly and quickly, and ensured the victory of the Tang Dynasty army in the Quartet, which was the condition of "the speed of the soldiers".

If Su Shaowei's railroad is completed, it is conceivable that the speed of transferring troops and transporting grain, grass and baggage will be at least twice as fast; Moreover, the body of the soldiers and horses can also be optimally maintained, and they can fight when they get off the carriage; The loss of grain and grass in the process of transporting grain and grass, the cost of requisitioning the people's money, and the cost of grain will also be greatly saved -- the so-called "ten cents of grain is transported, and five cents is used on the road", and the war also burns money in this aspect. Counting them down, the benefits of railroad carriages don't stop there.

However, there are also many problems.

First of all, such a large project must be a huge expense, can the household finance support it?

Second, the maintenance of the railroad after its completion, including the protection and maintenance of the rails, must involve the establishment of a new military force: the railway protection army.

Third,......

Li Yuzhen had already thought of one, two, three, four, and five issues, all of which needed to be considered and resolved in advance.

As for the technical problems of building railway tracks, Li Yuzhen has no worries, according to Su Shaowei's analysis, rail laying does not need to be built on a good road surface, as long as the foundation does not collapse, which is much easier than building military roads, as for the engineering problems of opening mountains and mountains and building tunnels, the technology of the Ministry of Industry and Transportation Department has long been able to support.

"Aweng, I think this direction is right, but there are a few problems that need to be solved, one of which ......"

Li Yuzhen sorted out his thoughts and told the Emperor one by one.

"It's built, and this is the new powerhouse of the empire."

Li Yuzhen's eyes sparkled.

The emperor nodded, mentioned a few points of his own, and said: "Ten years ago, because the heir was unknown, and this item was extremely involved, I put it aside for the time being. Now there are no worries, and the conditions in all aspects are more mature than ten years ago. Your Father and I will fully support you. ”

"Yes, Awn."

Li Yuzhen felt his grandfather's wholehearted trust, felt warm and moved, and felt more and more heavy on his shoulders, and could not live up to his grandfather's trust and expectations.

"Su Shaowei is available, you can use her well."

The emperor did not mean that he was able to behave—which Li Yuzhen knew—but that she would not become Wei Chongrun.

Even if he does not support the apocalypse, he will not oppose Li Yuzhen taking power.

"Still, I still have to beat the side drum."

The Emperor said again.

"Yes, my grandson understands."

Li Yuzhen nodded understandingly.

***

Coming out of Ningshou Palace, it was already two or three o'clock, and Li Yuzhen thought that his father and mother had already rested, so he didn't re-enter. Palace, directly out of the palace from the Yanzheng Gate. Guan Xia approached the side horse and said: "Before, the princess's mansion came to report that Xiao Seventeen Langjun had returned to the mansion at the time of the unitary time. ”

Li Yuzhen sighed, the horse's hooves stepped on the side street outside the palace city with a crisp sound, she suddenly dismounted her horse and said, "Go to the princess's mansion." ”

The princess's mansion of Qin State is in Changle Fang, opposite the Yanzheng Gate, after the side street, you can directly enter the mansion from the North Fang Gate, close and convenient, even if you walk at night, there will be no danger, Guan Xia and other close attendants did not admonish His Royal Highness the Prince's safety.

As soon as Xiao Yan was about to go to the bed, he listened to the maid and said, "His Royal Highness the Crown Prince has come down." ”

Li Yixun was wearing a bedgown, leaning on the pillow and giggling, and said with a bit of fun: "You ran around all day today, and someone came to ask you." ”

This "knocking" is not a kowtow and respectful inquiry, but a real "knocking" question—knocking and asking.

"I went to visit the fourth sister-in-law, where is Hu running away." Xiao Yan said with a smile while taking a straight shirt and putting it on the outside of his bedclothes, but he also knew that he was going to be questioned when he went out rashly, and said to his mother, "Auntie, you rest first." I'll go back when I go to see Zhaohua. ”

"Well, go ahead, go ahead." Li Yixun picked up a ribbon from the pillow and waved it, and instructed the maid, "Give the prince a cup of tea." In the evening, the fire is lowered. ”

The maid smiled and saluted, "Oh." ”

Xiao Yan was speechless about the bad taste of her own mother, stepped forward to take the ribbon in her hand, tied up the long hair that had been untied at will, took the maid out of the inner bed, put on soft shoes in the rest room, and went out along the corridor to the flower hall.

The flower hall is a place to meet guests, Li Yuzhen came over at night, of course, he didn't want to disturb the eleventh aunt, so he didn't enter the reading room and sat in the flower hall.

She was holding a glass of water in her hand.

Hearing Xiao Yan's footsteps coming in, he didn't raise his eyes, and asked indifferently, "Where did you go?" ”

Xiao Yan made a gesture to the maid behind him, which meant "no need to serve tea", and the maid bowed down and stood on the porch with the prince's maid.

Xiao Yan thought that Li Yuzhen was also worried about her safety, so she didn't get angry at Li Yuzhen's questioning attitude, sat on a circle chair a little away from her, and replied to her gently: "I'm going to Wuliangguan to visit the fourth sister-in-law." ”

Li Yuzhen lifted her eyelids to look at her, and did not speak.

Xiao Yan coughed, "With Wei and Chen, there will be no problem." Besides, there is really a case, I still have the hairpin of Dao Zhenzi's predecessor, at least, there is a time to keep one or two breaths,—— Master Uncle is in the East Palace, and it will also appear instantly. ”

She is not a hot-brained, willful person, and she still has thoughtful considerations about her safety when she goes out.

Li Yuzhen still didn't speak, only slightly pursed her eyebrows and looked at Xiao Yan.

There is a silent, heart-throbbing pressure in the flower hall.

There was deep affection in this pressure, which made Xiao Yan's head a little heavy.

She propped up her forehead and said, "It's too late, you've been busy all day today, go back to the palace early to rest." ”
