Datang: Li Shimin begged me to rebel

Li Ke's gaze was deep, and no one else would know about this matter, but in fact, Li Ke didn't care whether others knew or not.

Not to mention the others, even if Liu Zhao and the others knew about it, Li Ke didn't care. They couldn't blame Li Ke for passing the news to Yuan Gai Suwen, and they had to say thank you to Li Ke.

Because it was never Li Ke who made the choice, but Yuan Gai Suwen.

If Yuan Gai Suwen didn't know this news in advance, after Liu Zhao these people go back, not to mention their family members and friends, even the 27 of them would not be able to survive.

All Li Ke did was to adjust the order, and he even saved the lives of Liu Zhao and the others.As for how they choose and what they want to do, what does that have to do with Li Ke?

He, Li Ke, just opened his mouth to say something, and Li Ke didn't force them to choose how they chose.

Besides, maybe Li Ke was thinking too much, Yuan Gai Suwen wouldn't do that.

After leaving Chang'an City, Zhang Xi directly threw a few prairie-style money bags in his hand to Liu Zhao, and said viciously: "Hurry up and get out, if we see you appearing near Chang'an City again, His Highness won't let us Let's do it, we have to kill you secretly too! Hmph!"

After speaking, Zhang Xi turned around and left with the people.

"Boss, His Royal Highness King Qin, did you really let us go?" one of Liu Zhao's subordinates couldn't help asking.

"If you want to kill us, do you need to do this?" Liu Zhao smiled wryly, the atmosphere of the other party was far beyond their imagination, and Liu Zhao was already confused.

In addition to being confused, there is also endless panic. He is very conflicted in his heart now. He is afraid that Li Ke is right, which means that his family and... Liu Zhao no longer dare to think about it.But if Li Ke guessed wrong, then Liu Zhao didn't know how to deal with himself.

Are these things to be handed over to General Yuan Gai Suwen?

But based on his understanding of Yuan Gai Suwen, if this thing is really handed over to the other party, wait for their fate...

"Boss, what should we do?" Another subordinate was also a little dazed, or all of them were a little dazed.

"I don't know, but let's go back, after all, Goguryeo is our home." Liu Zhao paused for a moment, and then spoke softly.

"Boss... I'm afraid." One of the subordinates was silent for a long time, and then said.

Everyone knows what he is afraid of.

"Don't be afraid! Let's go back. I don't know what you think in your heart, but if something really happens after we go back, you can make your own choices." Liu Zhao took a deep breath, and then said.

After finishing speaking, he took out the book in his hand, "The content here is what His Royal Highness Qin Wang told us. If you want to hear it, I can read it to you on the way. You can discuss it with each other. Wait until the border At that time, I am afraid that this book will not be available.”

"No matter what the situation in our family is, if the general sees this thing, we will die."

"So, if you want to learn knowledge, remember it."

The others didn't speak, but Liu Zhao seemed to know what they were thinking, but first opened the purse to look at the money inside, and then said: "Let's go, to the next county, the money given by the other party is not enough. No, go to the next county to buy some pack horses."

The pack horse was not expensive, and the other party gave them a lot of money, and there was some silver in it. To be honest, Liu Zhao didn't even know why His Royal Highness King Qin did this. Could it be that they really expected them to help him with work?

It's just that he didn't dare to think about some things, and he didn't want to think about them before returning to Goguryeo.

People often feel that "life is limited", but they live like "life is infinite".

How many hundred years are there in life, think of the beautiful scenery on a good day, and let it go.

At the beginning of February, after receiving an urgent request from His Royal Highness King Qin, Yu Wenlin packed up the relevant materials and rushed to Chang'an. He hurried quickly, because the Weihe River had not yet thawed, so it took more than half a month to reach Chang'an. .

When he arrived in Chang'an, Yu Wenlin immediately came to secretly meet Li Ke, but this time it was not only Li Ke who met Yu Wenlin in Liangyi Hall, but also Li Shimin and Li Chengqian.

"Chen Yuwenlin has met His Majesty, His Highness the Crown Prince, and His Highness King Qin." Yu Wenlin was in a calm mood. If it was two years ago, he might have been very excited to see Li Shimin.

But now, he is no longer excited. In other words, Li Ke has broadened his horizons for him and made him understand what the real world is, so now he is not excited to see anyone except His Royal Highness King Qin. It must be His Royal Highness King Qin who has more advanced knowledge.

"Excuse me, your Yuwen family has been prone to produce craftsmen since ancient times. For example, the people who built Chang'an City are also from your Yuwen family." Li Shimin said with a smile.

"Thank you, Your Majesty, if it weren't for His Highness King Qin, craftsmen like us wouldn't be able to stand on the stage." Yu Wenlin said calmly.

Li Shimin: "..." If Li Ke didn't like him very much, Li Shimin would be angry, would you chat.

"Okay, stop talking nonsense, how about the ship I asked you to build?" Li Ke asked.

"Your Highness, if you provide the blueprints and we can't build the real thing, then we are a bunch of pure waste, and you can just drive us away." Yu Wenlin said bluntly.

Okay, since chatting with Li Ke is like this, Li Shimin will not be angry anymore.

"Is the ship finished now?" Li Ke nodded seriously and asked.

"Yes! We built two improved sailboats with a displacement of about 1200 tons. The load capacity is about 700 tons, and the full load displacement is 1900 tons. If the risk is reserved for 10%, the cargo load capacity is about 600 tons." Yu Wenlin directly A number is given.

"Ton?" Li Shimin raised his eyebrows.

"One ton is about sixteen stones." Li Ke gave Li Shimin an approximate figure.People like Yu Wenlin have already used the standard unit of measurement that Li Ke called. The main reason is that Datang’s stone and other units of measurement are often inaccurate, and it is difficult to convert, so Li Ke simply used tons.

Of course, this ton is not used casually. He found several sets of standard weights in the warehouse in his mind, and Li Ke took out a set to make accurate measurement prototypes for them.Of course, this thing can't be completely accurate, but Li Ke can only do so much.

At present, the scientific research of Datang does not need to be so precise. In later generations, the standard weight of one kilogram is calculated by Planck's constant. Of course, in this world, who will name this constant in the end, then Li Ke will not know. , he must not live to that point.

后世为了更高级的科学研究，标准重量是跟光速和原子秒共同计算出来的，很多现代度量衡都是可以相互换算的。普朗克常数h=6.62607015x10?34kgm2s?1

1KG=h/6.62607015X10-34m-2S。

Among them, meters and seconds are defined by the speed of light C and the resonant frequency ΔnCs of cesium atom 133 atoms, respectively.

光速c=299792458ms-1，因此1m=1/299792458c·s；

Cesium 133 atomic resonance frequency ΔnCs=9192631770Hz, that is, 1s=9192631770/ΔnCs;

It can be calculated by inserting the above formula.
