Word verification is just a form of encryption.

In fact, the encryption method in Chinese history appeared in the 11th century BC, during the reign of King Wu of Zhou, and the earliest record is "Liutao Yin Fu".

King Wu of Zhou used the Yin Fu as a talisman to carry out military confidential communication, such as one inch long for a big victory to defeat the enemy, nine inches long for breaking the army and capturing the general, and eight inches long for descending the city to gain the city.

In the article "Yin Shu", the same is true, a paragraph of military intelligence and military literature is split into three paragraphs, and three people hold military newspapers in their hands and go to the local place to summarize and learn about the military newspaper.

There is also a way called secret language, which is called the reverse cut method, and the incision and anti-incision of the usual context are derived from this, using dialects and code words to transmit military information.

After continuous evolution, there is also a method of word analysis, for example, when Wu Zetian leveled Pei Yan and Luo Bingwang uprising, he once cracked Pei Yan's word analysis method and dismantled Pei Yan's secret letter.

By the time of the Great Song Dynasty, the first set of code books in history also appeared, "Wujing General Essentials: Character Verification".

This set of codebooks can be said to be the world's first set of military general codebooks, and the summary is the Wenchen Zeng Gongliang and Duanming Hall Scholar Ding Du during the Renzong Dynasty.

Word verification is the use of poetry to transmit messages, and when Zhao Huan first saw the word verification method, he knew that China's cryptography had already been worn for 3,000 years.

The code method of transmitting military information has been a very common means in the Great Song Dynasty. The general held a copy of "Shuo Wen Jie Zi" and compared and translated.

However, this method of checking the character code, because it is cumbersome, is often used to transmit military information to the emperor, and the emperor's edict generally does not use this method.

Because the edict is not something that ordinary people can forge, the generals of the border army have all seen what kind of honor the holy decree is, and they have also seen the format of the holy decree.

didn't think about it, this time it was used by Zhao Gou to use this handle.

Zhao Huan said to Zhao Ying: "Inform Yu Shi Zhongcheng and the Privy Council to hand over." The transmission of military information is carried out using the word test. The edict was also summoned by word examination. ”

What does Zhao want to do?

Zhao Huan is clear, he Zhao wants to be the emperor!

Now that the time and place are favorable, Zhao Gou is fully mature, and he will not let go of this opportunity.

When the Jin soldiers besieged the city, Bianjing was besieged, Zhao Gou tun 200,000 soldiers and Yinglong Mansion, but did not move, Zong Ze was the main anti-Jin, and was also deposed by Zhao Gou, Zhao Gou Lin'an was called the emperor, and refused to return the capital Bianjing.

Then he was at ease with the court, and his desire to be the emperor was obvious.

And now, the soldiers in his hands are all in the north, and the Bianjing army has only 20,000 elite Yongding troops.

Outside and Inside, for the current Zhao Huan, there is only one choice.

Zhao Huan chose the Northern Anti-Jin people, so Zhao Gou would have a heavenly time.

The Yangtze River is in danger, but according to millions of soldiers, if you hold Jiankang, you will hold the entire south of the Yangtze River.

This is the geographical advantage, in fact, the Southern Song Dynasty also relied on this geographical advantage, and it became more than 180 years before it was completely ended after the Battle of Yashan.

In Xuanhe's three-year scorched earth strategy, one out of ten households was drawn out, and all the Chinese homes were extracted in the name of subsidizing Fang La. The people of Jiangnan are not there, Zhao Gou now has people, as long as he has three chapters of the law with the people of Jiangnan, the people of Jiangnan will naturally support him.

After all, the Great Song Dynasty has only been gone for one hundred and sixty years, and it has not yet come to an end, and everyone is still grateful to the Great Song Dynasty.

If Zhao Gou is supported, there will be no so-called rebellion, and the people's hearts can be used.

The most critical of these was Zhao Huan's Juntian policy in Hedong Road, Guanzhong, Yunzhong, Yanjing, Hebei and other places, which drove the landlords away, and the landlords fled to the south.

And there are many landlords in Jiangnan itself, as long as they are slightly connected, in order to prevent their own interests from being harmed, they will coerce the ignorant people of Jiangnan to participate in the support of the establishment.

The people are ignorant and blindly obedient, and Zhao Huan doesn't think they can tell the difference between Zhao Gou and Zhao Huan.

Zhao Gou, this guy is ruthless enough.

Zhao Huan sighed. But now he is powerless.

He is training the new army, so Zhao Gou doesn't know the importance of the new army?

Now that the forbidden army has broken up as a whole, in terms of military strength, Zhao Huan has at most 20,000 Yongding troops than Zhao Gou.

And the 20,000 Yongding Army are all Northern Army, a group of landlubbers, not good at water warfare.

There is no Yangtze River Bridge for Zhao Huan to use now.

Now to cross the Yangtze River, you must use a boat, and the Yangtze River will not freeze......

Zhao Gou is definitely a smart person, the timing he chose was very good, stuck in the right time, and did something beneficial to him Zhao Gou.

Selfishness is synonymous with him.

Trouble.

Li Gang was overjoyed to come to the Xuande Gate with the news that Zhao Ji was preparing to return to Beijing, but when he was waiting for the palace gate to open, he saw Cai You hurrying out of the Dongye Gate.

This Privy Council matter is now a personal seal, because Zhao Huan led the Yongding Army to defeat the Sixteen Prefectures of Yanyun, and now in Bianjing City, the new emperor speaks with all his words.

This Cai You is in the court, he doesn't say a word, whatever the official says, he Cai You will do.

Entering the palace at noon, is there any big deal?

Li Gang came to the Wende Hall with the letter and said loudly, "Official, congratulations!" Emperor Taishang has decided to return to Beijing, and is leading 80,000 soldiers to return to Bianjing. ”

Zhao Huan asked with a sinking face, "Li Dazai, the Emperor Taishang took away 400,000 soldiers and horses, why is there only so much left now?" ”

As soon as Zhao Huan heard the figure of 80,000, he knew that he was going to suffer, because according to Kang Lu's confession, now Zhao Gou is in Jiangnan!

The speed of the 400,000 people is too fast!

Problematic!

When Li Gang heard this, the joy on his face slowly disappeared. It's just that the intelligence is limited, and he really doesn't know how the 400,000 forbidden army collapsed in such a short time.

"Li Dazai, come and see this." Zhao Huan handed the military report from Pingzhou to Li Gang, and said worriedly, "He, King Kang, I'm afraid I'm going to do something big!" ”

After Li Gang received the notebook and studied it carefully, layers of cold sweat broke out on his forehead.

"Official, Jiangnan is the granary of the Great Song Dynasty and the main source of commercial taxes for the Great Song Dynasty." Li Gang said cautiously, reminding the official family that this incident was not unusual.

"Ten thousand guan of taxes, Jiangnan alone has contributed more than 30 million guan, the official family, if this King Kang seeks to stand on his own in Jiangnan again......" Li Gang couldn't go on, because if this matter is true, the consequences are unimaginable.

When Zhao Huan saw Li Gang's expression, he knew that this Zhi Duoxing was really useless now.

This is the general trend of history! Do not be hindered by cunning.

What to do?

It has become a problem in the hearts of the two monarchs and ministers.

"Make peace with the Jinren? And then send troops south to quell the rebellion? Li Gang asked tentatively.

But Zhao Huan suddenly laughed, this is another multiple-choice question, discuss and withdraw tens of thousands of soldiers and horses, beat Zhao Gou, just like playing.

Just like when the seed master asked him, it was a multiple-choice question like whether to continue to attack Yunzhong Road or return to Beijing to quell the rebellion!

Outside and inside, fixed multiple-choice questions, Zhao Huan still chose to go outside this time.

Zhao Huan shook his head and said, "The movement of the troops in the north remains unchanged, and the training of the new army has 30,000 flying troops, which is enough to quell King Kang's rebellion!" ”

"Time is on our side and I believe time will make the right choice. I, the king of the Great Song Dynasty, will definitely be able to pacify the Zhao Gou who divided the territory! ”
