The people in the Taiji Hall left in twos and threes, and Zhang Yang looked at Li Chengqian walking towards him, "His Royal Highness the Prince, are you going to rest?" ”

Li Chengqian said with emotion: "There will be many people who stay awake all night tonight, and I really can't understand why the iron box that the two generals couldn't open with all their strength before can easily open it in the hands of the young slaves. ”

"Because the water can expel the air, the iron box forms a short vacuum chamber, although this time is very short, that is, the small box can be opened with a little external force in this vacuum chamber."

Li Chengqian looked down and thought, trying to understand what a vacuum was with the only knowledge he had.

After a while, Li Chengqian smiled helplessly, "The Tubo Zhuoga lineage has been a wise man for generations, and the people of their lineage are respected as wise men in the Western Regions and even Tubo, which is why Songtsen Gampo sent him here. ”

"At the beginning of the battle in Liangzhou, it was also the people in their tribe who helped Songtsan Gampu to arrange troops, which was the reason why Niu Jinda chased into Tubo and was besieged, they lived under the sacred mountain in Tubo and the shore of the holy lake, these people have a very high prestige in all ethnic groups, whether it is to lead troops to fight, to cure diseases and save people, and even now come to Chang'an City by the order of Songtsan Gampo."

"Naturally, there is no shortage of strange people in the Central Plains." Li Chengqian walked outside the Taiji Hall and smiled, "Zhang Yang, after tonight, you will be famous all over the world." ”

Listening to the prince's words, Zhang Yang glanced at Li Xiaogong, who was still standing aside, and said in a low voice, "Let's go see Your Majesty." ”

"Come with the old man."

At this moment, there are still three or five palace maids left in the Taiji Hall who are cleaning up.

When the ministers left, the most honorable place in the Central Plains returned to its former silence, and it was even a little gloomy.

The infant child fell asleep and woke up, the corners of her mouth were still drooling, Li Yue hugged and took out a handkerchief to wipe her saliva.

Xiao Wu didn't have much energy, and he had to go to see His Majesty at this moment when it was late at night.

Before coming to the Ganlu Palace, there were three or two guards guarding here.

Li Lizhi pushed the stroller over, "The queen mother asked her to draw a picture, and she can also make it herself in the palace in the future." ”

Li Yue put the child in the stroller, and then she relaxed her arms, "Lizhi is really sensible." ”

Seeing Xiao Wu yawn, Li Lizhi was still very energetic, "Let's wait outside the hall." ”

The two little girls sat on the stone steps in front of the hall, and girls of this age liked to whisper the most.

The old eunuch stood outside the hall, "Your Majesty said that it is good to enter the hall, and there is no need to pass the ceremony." ”

Li Xiaogong walked into the Manna Hall with his steps, and the couple and their children also walked into the hall.

There was an oil lamp lit in the Ganlu Palace, and Li Shimin was sitting on the upper seat, holding an iron ingot in his hand.

Also sitting on the side was Empress Changsun.

"Okay, no need to be polite." Li Shimin interrupted Li Xiaogong's salute, "The Tibetan envoy told me the conditions before, and then let him enter the Taiji Palace. ”

Li Xiaogong bowed his head and said: "If you lose this battle of wisdom, as long as Your Majesty gives an order, the general is willing to lead troops to Tubo to capture Songtsen Gampo." ”

Seeing Li Shimin's gaze looking at him, Zhang Yang frowned and stared at the iron ingot in his hand, "Your Majesty, it's not early, can you say it tomorrow?" ”

Li Shimin didn't pay attention to this, and the young courtier couldn't help but fall asleep?

Empress Changsun said to the palace maid on the side: "Give me a seat, pour tea." ”

The chair was moved into the hall, Zhang Yang took the tea again, and drank a sip of hot tea, which made him feel a lot more energetic.

Those present were all their own family members, the queen and His Majesty, and the king of Hejian County.

To be more precise, the conversation in the temple at this moment should be regarded as a negotiation with one's own family.

The atmosphere should be relaxed.

Looking at Li Xiaogong on the side again, he really didn't see it, picked up the pastries on the side and ate them.

"Zhang Yang, the Tibetan strategy you told me before is now effective?"

"The Foreign Affairs Yuan has been keeping an eye on the development of the situation."

The emperor's gaze wandered back between Li Xiaogong and Zhang Yang, and after a quiet moment, he stood up again and handed the iron ingot to Li Xiaogong, "Look at this." ”

Li Xiaogong looked at this iron ingot suspiciously, "Back to Your Majesty, it is a good piece of material in terms of quality and condition." ”

"Do you know where this piece of iron came from?"

"If it is forged into a knife, it will not be worse than the horizontal knife in the army today."

Li Shimin carried it with both hands, "This iron material came from Lishan, and Qingque was sent by people." ”

Zhang Yang replied: "This is one of the processes of our Lishan technology, and this kind of iron material needs to be used more widely. ”

"But Qingque only showed me the results, and didn't say anything about the forging method of this kind of iron."

As an emperor, he likes to give others thinking questions, and there is nothing more than saying that the forging method of this iron material should also be told to the court.

It was not wrong for Li Tai to show Li Shimin the results, hematite was related to ordnance manufacturing, and letting the emperor see the results could also make him feel at ease about Lishan.

Zhang Yang bowed and said: "The casting of Lishan is only used for production and manufacturing, not for casting weapons, and it all depends on His Majesty's promise to Lishan, so that our casting technology in Lishan can be taken to a higher level." ”

Li Shimin looked out the window and didn't make a sound.

This is obviously not the answer that Tian Khan wants.

Li Xiaogong took a step forward, "Your Majesty, the people used in Lishan are nothing more than villagers who farm. ”

Seeing that Li Shimin still didn't speak, Zhang Yang said again: "Lishan can hand over this iron casting method to the court, but I have the conditions. ”

Li Shimin sat down again, "You and I are a family, and you still have to negotiate conditions?" When you came to pay New Year's greetings, you said that you would share the fruits of Lishan with the DPRK and China."

"Can the people in the DPRK be trusted? Won't the technology that Lishan has worked on with great difficulty leak out? ”

"Are you questioning my intentions?"

Seeing that the tone of the conversation between Weng and his son-in-law was getting heavier and heavier, the eldest grandson and queen were very annoyed holding her forehead, she was a monarch and a minister and a Weng son-in-law, and the relationship was complicated and the interests were even more complicated.

Li Xiaogong has been eating, so it is considered a supper, and he does not intervene.

The sound of laughter coming from the stroller, I don't know what the child is laughing at.

Li Shimin's face was blue, he also hoped that Datang's weapons could be sharper, and with the casting technology of good iron, it was inevitable to get it now.

"I'm not questioning your intentions, I hope that the technology can be safer, and hundreds of people from the Ministry of Industry, the Ministry of War, and even the Prison of Manufacturing, can these people be completely kept secret?"

Empress Changsun knew very well in her heart that what made Her Majesty angry was because of Zhang Yang's conditions, every time she talked to this son-in-law, as long as the conditions were mentioned, which time was not extremely harsh.

This made His Majesty feel that Zhang Yang had used the negotiation methods of the Foreign Affairs Yuan on himself, the Heavenly Khan.

I often get angry because of this, and there are not a few things that are smashed, and the first time is to mortgage the entire Lishan and exchange it for a Gaochang.

That transaction was worth it to the DPRK, at least Lishan would not run away in Guanzhong, and only by getting Gaochang could he have the opportunity to hold Tubo hostage now, and even send troops to the Western Regions.

Empress Eldest Sun sighed: "Your Majesty may wish to listen to the conditions. ”

Li Shimin waved his sleeves and said, "Speak." ”

Zhang Yang crossed his legs, leaned back against the chair and held his temple with one hand, "Lishan handed over the technical secret recipe to Your Majesty, Your Majesty can only see that it cannot be used for casting, and you can't give it to anyone." ”

When the words fell, Li Xiaogong sighed.

Li Shimin immediately clapped his eyes, "You might as well not give it to me!" ”

Zhang Yang stood up and replied: "Then if there is a weapon made of this kind of iron in Guanzhong, who will we Lishan shout injustice to, Your Majesty has not thought about it!" ”

"I ......" Li Shimin was so angry that the three corpse gods jumped violently, "You are strong and reasonable." ”

Zhang Yang drank the tea in the tea bowl, "This is to ensure the future, I am all for Datang." ”

"Aren't you just trying to make money?"

In the dead of night......

The sound of the quarrel between His Majesty and Zhang Yang came out of the hall, and even the guards in front of the palace who were originally dozing off were in a lot of energy, curious about what was going on.

Xiao Wu and Li Lizhi sat on the stone steps in front of the hall, leaning against each other and already asleep.

The palace maid intimately put on some thick coats for the two, Xiao Wu is also the queen's daughter, not to mention Princess Changle.

Don't dare to let the two girls catch a cold.

Hearing that the noise was getting more and more fierce, the two guards lifted their belts and walked into the hall again.

Seeing the guards coming, Li Shimin shouted, "What are you doing here?" ”

His Majesty scolded so much that Zhang Yang was also standing in the hall at this moment, only three or two steps away from the monarch and the minister.

The guard glanced at the situation in the hall, lowered his head and said, "Humble duty...... The lowly came to escort him. ”

Li Shimin waved his sleeves and said: "What kind of driver!" Get out of here. ”

"Whoa!"

The two guards left in a panic.

The quarrel in the hall continued, and Li Yue held his forehead, but he was also speechless for a while.

If the husband retreats, the father will not be so angry.

It is related to the interests of Lishan and the security of the future, and the husband also has the reason of the husband.

The queen and Princess Runan have a very tacit understanding not to speak together, this kind of thing is not to help anyone.

Zhang Yang put down the tea bowl in his hand, "I only have money in my heart?" If I didn't care about Sheji, I wouldn't have handed over Gaochang to the DPRK. ”

"I miss you for treating Yue'er well, and tolerate you everywhere."

"Your Majesty doesn't understand technology, has no common sense, and has to point fingers at Lishan, I have endured it for a long time."

"Tell me again!"

Seeing that the anger was getting bigger and bigger, Li Xiaogong hurriedly stopped, "Your Majesty, I finally cultivated my body, and Lu Zhaolin told me not to move my heart anymore." ”

"This kind of rebel, you teach me how to cultivate!"

"I have hundreds of households in Lishan, and thousands of people have to take care of them, can I not be cautious?"

Li Shimin picked up Li Xiaogong, "When I killed the enemy on the battlefield, the blood on the knife has not dried up, and today I ......"

"Your Majesty! Your Majesty! Li Xiaogong stopped in the middle, "This time the Tibetan envoy made it difficult, but Zhang Yang broke the siege, and read it for his meritorious sake." ”

Seeing the emperor's red and white face, Li Xiaogong gritted his teeth and said, "Your Majesty! The minister is willing to go to Lishan and stare at Lishan casting! But whoever steals iron and goes out will be killed. ”

Finally, Li Shimin calmed down.

The emperor is not worried about his son-in-law, and his son-in-law is even more worried about the emperor.

The two have been suspicious of each other for a long time, and the fire in their hearts has been held back for a long time.

Li Xiaogong bowed and said: "Your Majesty, Zhang Yang has been negligent in discipline since he was a child, he is a country boy, why bother with him, and the ministers will teach him how to be a courtier in the future." ”

Li Shimin snorted coldly and sat down.

Empress Changsun motioned to the palace maid to pour tea again.

The commotion in the hall was over, and they were a little refreshed by the sound of the quarrel, but in a moment they began to feel sleepy again.

Weng and his son-in-law glanced at each other, and then looked away with a little more disdain.

Empress Changsun said with a smile: "It is said that the salt from the lake in Tibet has arrived, and it will be sent to Lishan early tomorrow morning." ”

Li Yue got up and saluted, "Thank you for the arrangement of the queen mother, Lishan is indeed short of salt." ”

Empress Eldest Sun took her hand, "The queen mother should also think more about you." ”

The queen and princess were still talking in a low voice.

Li Shimin poured a large sip of tea, and most of the anger in his heart disappeared.

Li Yue said again: "It's okay to let the husband and the father quarrel, and the monarch and the minister should also be honest with each other, and they can get along better in the future after making it clear." ”

Empress Eldest Sun smiled and nodded, "Yue'er is exactly what the queen mother wants. ”

The harmony between the queen and the princess formed a huge contrast in the manna hall at this moment.

Zhang Yang and His Majesty look at each other with disgust.

"Is the technical breakthrough you Lishan said only for the moment?"

Li Shimin finally spoke again.

"The development of technology can affect all aspects of life and production......"

Li Shimin's eyes were still looking out the window, and Zhang Yang's words were in his ears.

"Judging from the development process of ancient times, the ancients drank blood for thousands of years, from hunting to farming, to manufacturing living utensils, I call this the Stone Age, in these thousands of years until the emergence of iron tools, civilization has also formed a huge transformation."

"At that time, Yao Shun became the leader of the people, and then Zhou Tianzi formulated the calendar and national system, and the civilization and prosperity of the Central Plains went to a new level, and the world was divided and merged to the first emperor, and the car was the same track and the same text, and when it came to the Han Dynasty, the Central Plains people had a common identity, that is, the Han people."

"So far, the people of the Central Plains have a very strong cohesion and the concept of unification of the world, which is another big leap, whether it is etiquette or the official system has reached its peak."

"Your Majesty has found it, from the ancient times when Ru Mao drank blood for thousands of years, to now since the application of iron tools, the rapid change of dynasties, in just nearly a thousand years, has created a magnificent era."

Listening to these words, Li Shimin inexplicably felt his blood boiling, and the ambition in his heart was burned again, and I also wanted to establish a magnificent era.

"Ru Mao drank blood for thousands of years, bronze is a thousand years, but it only took a few hundred years for cast iron technology to make a leap, and each change time is getting shorter and shorter, I call this a technological leap, and what Lishan is doing now is to make technology leap again."

"At that time, my teacher in Qinling said that the concept of technological explosion, when theoretical knowledge is continuously popularized in practice, and all creations are combined, it is not a leap that can be measured, it is a creativity that can cross one peak after another."

"Do you really have such a teacher in Qinling?" Li Shimin's faint voice came.

It was very uncomfortable to be interrupted from speaking, Zhang Yang took a deep breath and retracted his thoughts, "Your Majesty, don't you believe it?" ”

The Emperor responded with silence.

Zhang Yang was also silent, drinking tea and thinking that if it went on like this, it would be dawn.
