"Nope."

Song Beiyun shook his head and said, "I don't have so much time to spend time with a prince of Liao, it's not worth it." ”

"So what's going on here?" Zhao Xing also sat there worried: "He is pressing step by step now, which means that if I don't agree to let you go to Liao State to preside over this matter, he will not let go." ”

"I can't help her."

Song Beiyun rubbed his nose: "If I can be threatened by her, then my name is still Song Beiyun?" Besides, do you know what will happen if I fall into her hands? ”

"What will happen?"

"I won't be able to come back, and I will be detained in Liao." Song Beiyun gently tapped on the tabletop: "Really, do you know Su Wu Shepherd?" Arrange for me to go to the edge of Weishui to feed the cattle, and you say what to do. ”

Of course, Xiao Song coaxed, he was a person who spared his life, and he had already offended Xiao Huya here, and now people opened their mouths to ask Zhao Xing's dignitaries, and used trade offers as a hostage. If he was really taken to Liao, wouldn't he be round and flat and let that little tiger tooth handle it? Is this worth it?

"Who am I?" Xiao Song pointed to himself: "I want to hear your opinion." ”

"Well......" Zhao Xuan was silent for a moment: "Ruthless, unscrupulous, thick-faced, brutal, resourceful, greedy for life and afraid of death, arrogant and lascivious." ”

"Well, there's not a good word." Song Beiyun sighed and said, "Okay, I admit it." You also know that I am a person who is greedy for life and afraid of death, if the sword of the Liao Kingdom is really on my neck, what do you say I will do with my character? ”

Zhao Xing nodded lightly: "I understood a little when I arrived, but you also said it too directly, and you were also tactful, if you don't say it for me, you just say that you are willing to smear the liver and brain of the Great Song Dynasty!" ”

"Ouch...... Are you tired of hearing this kind of talk on weekdays? There are a few loyal people who will be really loyal, what can you do if people secretly poke and poke the Great Song Dynasty? Look at how good I am, I tell you clearly, I'm greedy for life and afraid of death, don't push me into the fire pit, I may be able to withstand money and beauty, but I really can't withstand torture and beating. Song Beiyun waved his hand and said: "Don't worry about this matter, I have a way to deal with this big one!" Emperor! Child! ”

"Oh? Look at the way you grit your teeth...... It seems to be hateful. ”

"Can you not hate, just ...... It's complicated here, I won't talk to you more, that's it, you can talk to her how you want, and I'll deal with the rest. Song Beiyun got up and drank all the water in Zhao Xing's cup: "You didn't even drink saliva this time, you are really not interesting." ”

After saying that, he walked out: "Let's go, I'm busy over there, and the boiler has exploded again." ”

"Hmm." Zhao Xing nodded.

However, when Song Beiyun was halfway through, Zhao Xuan suddenly shouted: "Song Beiyun!" ”

Song Beiyun stopped, tilted his head softly, and didn't even want to turn his body, but symbolically tilted his neck back slightly: "Huh? ”

Zhao Xuan saw him like this, the appearance of a bullshit wolf Gu is clearly the appearance of a wolf dog! That lazy look, no matter how you look at it, is a lack of virtue.

"I called you, aren't you even happy to turn back?"

"Hi...... Okay, okay, I'm turning. Song Beiyun turned around: "What are you doing?" ”

"Be careful, pay attention to your body, I don't want my nephew to be born without a father."

"Got it." Song Beiyun turned around again, raised his hand and shook it: "Let's go." ”

Watching him disappear into the depths of the Imperial Garden, Lao Wang leaned in and said with a smile: "Official, you should rest assured now." ”

Zhao Xuan didn't speak, just laughed a few times: "How can there be such a splash in the world." By the way, last time, you took care of the murder and plundering of the traitor for that Zhao Cheng's arsonist? ”

"Back to the official's house, everything has been dealt with properly, and the people who know about this matter in the Imperial City Division have all been silenced, and they all know that they will die if they do this." Lao Wang bowed down and said, "The official family ......"

"I know what you have to say, so when you are old, stay with him, so that I can always remind this guy, lest he lose his humanity one day, and he will certainly not treat you badly."

"Thank you for your kindness......"

"Oh, yes." Zhao Xuan turned around and said, "These days, you have trained Xiaoyu well, and I plan to let him take your place." ”

"The old slave understands."

After Zhao Xuan finished speaking, he glanced at the cup that he had been pinched out of a black handprint by Song Beiyun with disgust, and sat there with a long sigh: "In the end, no one is perfect, if that Kuang Yusheng can have Song Beiyun's ability, and Song Beiyun can have Kuang Yusheng's heart, my Great Song will definitely have great ambitions." ”

"Official...... Forgive the old slave for talking too much, according to the old slave, even if he relies on this Song Beiyun, the Great Song Dynasty can also make great achievements, but it is just ...... Maybe it's not that good-looking. ”

"That's it, the affairs of a country, how can there be a reason to look good or not, if he can make the Great Song Dynasty re-enter the Central Plains, even if he gives him a prince with a different surname, what is the difficulty!"

Lao Wang sighed lightly.

"What are you sighing for?"

"I'm afraid that the old slave won't be able to see that day, but the official family will definitely be able to see it."

"Hahahaha, I'll just let him hurry."

And after Song Beiyun returned to the workshop, he didn't have time to think about the round-faced little tiger tooth, so he went directly into the boiler, not caring at all about being disgraced.

Two hours later, it was almost dusk, and he was sitting next to the boiler with a group of master craftsmen and a few people from the R&D department with a bowl in his hand, discussing how to increase the tightness.

"If you want me to see, just make the stove bigger, make it less powerful, and just don't blow it up, so that the pipe won't be easy to come out of that ......."

"Steam hammer." Song Beiyun added: "The short-term strong impact at the exit is called a steam hammer. ”

"Yes, yes, yes, if you don't say that the main family is powerful, you will know what is wrong as soon as we say it at that time." One of the master craftsmen nodded again and again, "If only I didn't have this steam hammer." ”

There will definitely be a steam hammer, which is water hammer or water hammer, and water hammer can occur in any steam or condensate line, especially in multiphase flow systems, such as condensate two-phase systems. Obviously, as long as there is condensate in the steam system at the same time as flash steam or new steam, there is a two-phase state of water vapor, then this thing is unavoidable.

This thing is a bit similar to the power of the first sip of water when you turn on the faucet, but the power of the steam hammer is more terrifying, and it is uncontrollable with current technical means.

The only solution is to reduce the steam pressure and increase the cross-sectional area of the pipe, but this can easily lead to a lack of power......

Anyway, in general, the doorway in the boiling water alone is already a headache, and these days, more than 80% of the explosions are caused by this water hammer hedge, and the furnace material can't bear it.

The sealing performance effectively alleviates this phenomenon, but ...... The tightness can't be solved, so we can only temporarily slow down the research and development process of the boiler for now, and wait for the birth of sealing materials and new furnace materials before making plans.

In this way, Xiao Song couldn't help but feel a little frustrated, but he naturally understood, the steam engine...... It is the jewel in the crown of human industry, the product of many years of experience, mistakes and the accumulation of life, and there is no result in quick success.

"Let's start with a small goal." Song Beiyun pointed to the bulky boiler next to him: "It, let's think of something so that it can pick up a hundred catties of things!" ”

After saying that, the master craftsmen said that they would do their best, but they only did their best, because ...... All theories and knowledge are new, and they need time to explore and explore slowly.

"What a technological desert." Song Beiyun sighed secretly, and then raised his head to look at the people in the R&D department: "By the way, has the Tiangong Kaiwu Chronicle begun to be compiled?" ”

A scholar from the R&D department was also standing next to him with a bowl, and when he heard Song Beiyun's words, he immediately stepped forward: "Lord Song, you have already started compiling." ”

Song Beiyun nodded and looked at the scholar who was talking to him: "How old are you?" ”

"The student is fourteen years old."

"Fourteen, what a year, what's your name?"

"Student Shen Zhou, his father is Dali Temple."

Song Beiyun nodded and continued to eat, but he didn't care, but suddenly he woke up suddenly and turned his head to look at Shen Zhou.

"Lord Song, what's wrong?"

"It's okay...... It's okay......" Song Beiyun shook his head with a smile, seeing that the people around him were second monks and puzzled.

However, Xiao Song didn't say anything, because what he knew was too bizarre, and people would only think he was crazy when he said it. As for why he was surprised, it was because of this Shen Zhou......

That's Shen Kuo's father! And Shen Kuo is the strange person who left a strong mark in the history of Chinese science and technology, in mathematics, physics, astronomy, geography, chemistry, water conservancy, medicine, economy, military and art and other fields have unique achievements, compared with foreign scientists of the same period, he is unique, if the East has always attached importance to natural science, then even after the European Renaissance Leonardo da Vinci can only be called the West Xiao Shen Kuo.

It seems that cultivating a talent is definitely not accidental, now Shen Zhou is only fourteen years old, maybe not fourteen, at most a little more than thirteen years old, after all, men fourteen can be crowned, but he is still a name.

"Shen Zhou, what about Shen Zhou?"

"The students are here." Shen Zhou stepped forward: "What do you have to say about Lord Song?" ”

"If you want to give birth to a son in the future, you must name him Shen Kuo, and then I will teach him personally!"

"Huh?" Shen Zhou was stunned: "What does Lord Song mean?" ”

"You don't care, just remember."

"The student wrote down ......"

Speaking of this, Song Beiyun thought of Xiao Bao Zheng, who had a relationship with him before, and he should still be forced to cry and read at home by rattan and shoe soles.

Song Beiyun sat there happily thinking about the scene where these historical ministers would respectfully call him Lord Song in the future, which was called a beautiful thing.

"Lord Song, there are people looking for you outside."

"Who?" Song Beiyun glanced up: "Didn't you see that I was so busy?" ”

"It's still the same person yesterday, he said that if Lord Song doesn't see him, he will definitely regret it."

"Can't she change her lines?" Song Beiyun frowned and got up, and ate the rice in his hand in three bites and two bites: "Why is this person so annoying!" Just say I'm not there! ”
