Zhao Yun controlled himself and tried not to see that the Lord was knocking Zhang Fei on the head.

Kneeling on the side, he sighed softly with the military advisor:

"This Tang and Han, what a kind."

For Zhao Yun's sigh, Kong Ming nodded silently.

After all, it's just over 400 years away.

And if governing the country is based on normal circumstances, it is natural to refer to successful cases.

The martial arts of the Tang Dynasty may have been learned from the troubled times, but Wenzhi naturally had to learn more from Han.

However, thinking of the familiar cause of decline, Kong Ming couldn't help but sigh:

You don't have to learn to be this similar......

"Zilong knows someone who is good at raising horses in the Northland?"

Zhao Yun shook his head honestly:

"There are horse officials under the command of General Gongsun, but most of them have nothing to do with the conservation and selection of later generations."

"His job is only to take care of horses and treat animal diseases."

Kong Ming knocked on his head and said with a smile:

"I forgot, General Gongsun chose horses because of the color of his coat."

But whether it's General Gongsun, who can take only white from Gunma.

Or this is Emperor Li Tang, who can leave 700,000 horses for his son.

They all have nothing but envy.

Yun Chang obtained thousands of good horses in the battle of Xiangfan, and now they are all taken care of as treasures.

Yide was still waiting for Han Sui and Ma Chao to send the first batch of horses they had promised.

The sum of these two is less than 10,000 horses, compared to the figure of 700,000, I can only look up.

……

Li Shimin of Ganlu Hall got up Huo Ran:

"How many horses do you win over the Turks?"

Fang Xuanling only recalled this slightly, and said:

"More than 70,000 horses entered the racecourse."

Of course, all the horses of the Eastern Turks are more than this number, but since they want to rule the other party, they naturally have to be merciful, and it is impossible to rob all other people's things.

Therefore, the final seizure is only this number.

Li Shimin calculated a little, and finally he was very pleased:

"I can't imagine that I, Tang, have such a great talent!"

"Compile this breeding theory into a book, and tomorrow I will personally write to Zhang Wanzai."

Speaking of which, Li Shimin also deliberately mentioned it:

"Respect for old friends, it's a blessing to be able to leave a name in history because of talent!"

Wei Chi Jingde's mood was even more complicated.

If he hadn't been mentioned, he would have really forgotten about this person.

Ten years ago, Song Jingang was defeated, and Wei Chi Jingde voted for His Majesty with Zhang Wansui.

He relied on bravery to shine, what about Zhang? None of the battles have been named.

Later, I heard that he took the initiative to invite Yingyang to raise horses, and I thought that the two people under the command of Song Jingang were drifting apart, but I didn't expect it......

At the beginning, this taciturn young general laid the foundation of a prosperous era with his own hands.

After mentioning Wei Chi Jingde, Li Shimin looked at the four words of Mingjun for half a life, and his mood was also a little complicated.

Judging from the number of horses alone, this Taixuan prosperous era is not as continuous as previously imagined.

It is more like the prince to inherit the foundation of Zhenguan, but it took a lot of money, and in the end Xuanzong inherited a Tang Dynasty with half of the national strength.

Outcome......

"The easiest thing to do here is to win in the military formation."

This is the sigh of the Tang Emperor.

Several generals who voted for Li Shimin after the defeat of the Ganlu Hall nodded:

Anyway, you won, what do you want to say.

Fang Xuanling and Du Ruhui knew why Li Shimin sighed, looked at each other tacitly, and remembered each other's sons.

couldn't help but nod silently together:

Who's to say it isn't?

Yan Liben couldn't help but feel a little angry.

If he can enter the office directly, he will disdain to enter the office with skills.

Although I think it's good to draw now, why can't I get used to the demeanor of these people?

sighed for a moment, and Li Shimin, who loves good horses, immediately fell into imagination with great interest:

"If you break through the Western Regions, I wonder if Zhang Wansui can raise hundreds of thousands of sweat-and-blood horses for me?"

Fang Xuanling and Du Ruhui also sighed, and they still have to write down what should be done:

"You have to consult the Ministry of Civil Affairs."

"Or should I ask Si Nong Temple directly?"

"Sinong Temple is appropriate."

The two nodded and wrote it down.

[During the reign of Gaozong, one of the evil consequences of Ma Zheng's corruption was that the troops lost their ability to react quickly.

It was still Pei Xingjian's battle of 300,000 people, and the Tang army was several times better than the Turks, but it was still a stumbling battle, and one of the reasons was that there were not enough cavalry.

Later, because Prime Minister Pei Yan distorted the facts, the two leaders were beheaded in Chang'an, and as a result, the Turks and the Tang Dynasty were completely on the same page as Pei Xingjian guessed.

The Turks have been attacking and plundering from different sides over the years, so bet that your Tang army will not be able to react.

Later, more than 20 years after Li Zhi's death, the Tang general Zhang Renyuan couldn't stand playing hide and seek like this, and moved the beacon system of the Han Dynasty back and made more scientific improvements, thus giving birth to the suspended attic-style beacon tower.

This kind of beacon tower can be seen as building a small house on a small earthen tower, just like our water tower today, but the upper and lower levels can only be climbed by rope ladders, so that even if they are attacked, the beacon soldiers left behind above can cut down the rope ladder and then light the fire to send a signal.

Zhang Renyuan also improved the signal of the beacon fire, requiring the beacon tower to signal each other in the early morning and at night, and raise a fire safely; Hearing the alarm, raise two fires; Seeing smoke and dust, three fires; See thieves burning wood cages.

Within a radius of 300 miles, Zhang Renyuan built 1,800 beacons, so that Shuofang was finally peaceful, and the Turks did not dare to cross the border, but Shuofang also laid off tens of thousands of soldiers and saved expenses.

Relying on the beacon, it only takes one night to transmit a signal from Liaodong to the Western Regions, and the beacon can be called the best means before the radio age............ One.

For example, in the era of Napoleon in France, some people incorporated cryptography according to the idea of Fengsui, and built a communication tower that was very advanced at that time.

It is still similar to a beacon, with a signal tower built every five kilometers.

Instead of burning flames, these towers have a T-shaped beam on top of it with a cantilever at each end that can be pulled by a rope.

Each cantilever has seven angles, and the beam can swing at two angles, so the tower can theoretically pose 98 different shapes.

And it works like a beacon, just observe the shape of a nearby tower, and then convey it to the next communication tower.

The messenger does not need to know the content of the message, and when the message reaches its destination, a messenger will decipher the content against the codebook.

The advantage of this kind of signal tower is that the messenger does not need to know the content of the message, but only needs to draw a scoop from the gourd.

The biggest advantage is, of course, the speed of propagation, which theoretically means that a signal can travel 1,000 kilometers in 20 minutes.

The device was quickly improved, such as the Austrian-built tower, which used electric lights, similar to Morse code for transmission at night.

Later, someone had the idea to incorporate a telescope that only needs glass, so that the distance between the two signal towers could be placed farther away, saving costs.

Soon after, however, the telegraph was invented, and such towers were soon phased out. 】

Kong Ming couldn't help but sigh again at the whimsical ideas of later generations.

The thing that came out of the light curtain that was said to be a code book made Liu Bei dizzy, but Kong Ming and Fa Zheng quickly saw the doorway.

Kong Ming was a little unsure:

"Seems to be derived from arithmetic......"

Fa Zheng is looking forward to the content of its depiction:

"Even if you can pass orders thousands of miles in an hour, you are strong."

Even Zhang Fei's face was a lot more cautious:

"If the beacon fire is a fire, it can only be used at night, which is very inconvenient, if it is a smoke during the day, it costs a lot, and it is easy to send a warning by mistake, so you only need to change it ......"

As a leader, Zhang Fei feels this most clearly.

On the battlefield, it is because of the fear of signal confusion and the transmission that does not change, so the only way to transmit the signal is as simple as possible by burning smoke.

Such as the simplest attack, retreat, victory, defeat, etc.

But if it can be separated by 500 miles, and it can accurately convey that "Fan Jiang, you will run 100 miles to the north for me, and then 50 miles to the west, and attack the rear of the enemy army fiercely", then the effect will be completely different.

"It's just that this state text seems to be quite simple to convey."

Fa Zheng studied it for a while, but scratched his head a little.

Kong Ming didn't care much about this, the text was different, so there was no need to completely emulate his generation.

The examples given by the light curtain were clear, so he quickly understood that there were only two things that were important in this set of transmissions: the secret language that both the sender and the receiver should understand, and the various combinations of markers.

Even without this T-shaped rocker, the same effect can be achieved with multi-color flags.

What's more, Kong Ming studied it, and it seems that short-distance communication is more useful in this kind of secret language.

And Kong Ming soon discovered a new name: "Telescope? Glass? ”

On the light curtain is a small figure sketched in a simple figure, holding a cylinder in front of him, aiming at a tiny signal tower in the distance.

"Only clear glass!"

In Chengdu's glass workshop, the impurities of the glass that can be fired today are still obvious, but some of them can barely be seen.

Kong Ming also discovered that when he looked through the glass, the things he saw would be obviously deformed.

In this regard, he planned to wait for the winter to go to Hanzhong and study it by chiseling ice instead of transparent glass.

But I didn't expect to see a similar thing now, so Kong Ming, who was almost fast, woke up:

"Packed in a cylinder...... Depending on the difference between convex and concave, what are the different effects? ”

"According to him, he seems to be able to see things in the distance?"

Kong Ming suddenly felt itchy, and he couldn't wait for heavy snow in Hanzhong tomorrow, so he immediately went over to try to get ice.
