There were 5,000 troops in the face of the battle, and now that the dust of the Great War in Hebei had settled, of course, it was impossible for any enemy army to dare to break into the hinterland of Qingzhou and march with swagger.

Things soon became clear that it was the 5,000 surrendered troops that Zhang Jaw had just reorganized to the south.

Although it was a surrender army, from the spirit of the soldiers, they could not see the usual depressed and cowering appearance of the soldiers, all of them were full of chests and shy, red faces, and from head to toe they were full of the taste of a mighty army. Looking at it from an uninformed point of view, it is certain to think that this is a triumphant heroic division that has returned victorious.

The soldiers lined up in a neat line, and under the command of the generals, they stepped on a straight and wide road on the vast land covered with ice and snow.

The military appearance is clean, and the morale is like a rainbow!

Xu Shu finally understood why the lord had to hand over the task of counterattacking Langya to Zhang Jaw.

In the Battle of Yuanshan, in order to hunt down Xi Zhicai, Xu Shu took away the elite of the special combat team, although the militia was numerous, but it was far from the extent of encircling the entire battlefield.

And the Taishan group is not a regular army, the war only relies on a brave spirit, and it is easy to escape after losing, the direct result is that the battle not only failed to wipe out the Taishan thieves, but even an important leader was not left.

In a sense, this is also Xu Shu's intention.

After all the success of the first battle, a bad breath is out, but in the long run, it is not a good thing. With the remnants of Zang Ba's army, the Qingzhou Army's counterattack on Langya became famous. Although Langya is actually occupied by Taishan thieves, it is nominally the territory of Xuzhou after all, and Tao Qian himself may not care that Wang Yu will include it in his sphere of influence, but Xuzhou's land heroes have always been worried about this.

With a name, things are much easier.

If you are beaten up, you want to fight back, this is human nature. It is also related to the face of the strongest princes in the world. If Xuzhou can't catch Zang Ba and the others and give them as gifts, they can only acquiesce to Qingzhou's retaliation.

By counting the prisoners after the war and assessing the battle losses of both sides, Xu Shu has a fairly accurate assessment of the strength of Zang Ba's remnants. The total number of bandits who escaped from the battlefield of Yuanshan was about 4,000, and considering that Zang Ba's army had completely dispersed at that time, some of them were frightened. may not have the courage to return to Langya, and the remnants of Zang Ba's army are only 3,000 at best.

Even if he managed to recover some before the arrival of the Qingzhou Crusade Army, it would be impossible for the strength to exceed five thousand, and it would be thankful that he could keep Kaiyang's lair, other places. I definitely can't take care of it.

However, Langya is a large region, and Qingzhou University can take the opportunity to take it into its pocket and completely open up the connection with Xuzhou.

This time, the risk was very small, but the credit was not small, and the lord deliberately left it to the general to open his jaw. He also made him surrender and rebel and regroup, which can be said to be a great trust.

is the so-called daughter buys horse bones, with the example of open jaw. It will not be difficult to pacify the tens of thousands of soldiers in the Battle of Hebei. Zhang Jaw was in charge of his own after the first surrender, and he didn't even have a supervisor in the army, which is even more exaggerated. He and his confidants' families are still in the Yanzhou region!

Such a person is believed in by the lord. What else do the other pawns have to worry about?

Xu Shu admired Wang Yu's courage and greeted him. I saw that the array of the army was opened and closed, and a fast horse came out of the crowd, and a military general with a somewhat elegant appearance bowed his hand from afar: "Long Yang Yuanzhi General has become a peerless name, and today the left and the left meet, it is fate, and Zhang Jaw is very happy in his heart." ”

Xu Shu didn't dare to slack off, and hurriedly returned the salute: "Don't dare to be, General Jun Yi is a famous general in Hebei, powerful in China, and I am fortunate to be a minister in the same palace with the general, and protect the Han Dynasty together. ”

After meeting with Wang Yu several times in the camp, Zhang Jaw had already realized the importance of the other party, although he was not pampered and arrogant, and he shook his majesty, but the anxiety of entering the Wang camp for the first time had been put aside. Even if he met Xu Shu, a multi-functional intelligence leader, he was neither humble nor arrogant.

Xu Shu also recognized Zhangjaw's military leadership, and when the two met and exchanged a few words, they both had a bit of a heroic meeting and a taste of sympathy in their hearts.

Of course, the two met for the first time, talked back and forth, and finally turned around in military affairs, only to hear Zhang Jaw sigh sincerely: "In the past, a certain person thought he was a soldier, but the field battle was easily broken by the lord, and later he was made as big as a fight by the lord with a few false information. ”

"I heard that the Yin charm used in the army was made after the lord and Yuan Zhi discussed and made, and I always wanted to visit in person to ask for benefits, but unfortunately I received the task of raiding Langya, thinking that I missed this opportunity to meet, I don't know when I will be able to see each other again.

"Where, where, Brother Jun praised the little brother falsely." Xu Shu waved his hand again and again: "The yin talisman used in the army is made by the order of the lord, and the role of the younger brother in it is just to pick up the missing pieces and improve the details. Brother Jun praises this, I really don't dare to take it. ”

The so-called Yin Fu is the military code for transmitting intelligence in the army, and the earliest record can be found in the earliest military work "Liutao".

The specific form of this secret method of communication is the fu. The symbol is made of copper plate or bamboo woodblock, and the face is engraved with a pattern, which is divided into two, and the pattern or size length is the symbol of secret communication. In the records of Liutao, there are eight kinds of Yin symbols, which represent eight common military situations, such as the total annihilation of the great victory, the destruction of the enemy army, the occupation of the city, the capture of the enemy general, the request for rescue, and the general running out of grain and grass.

Liutao is the work of Jiang Taigong in the Shang and Zhou dynasties, and to this day, there have been many improvements in the art of war, which can only represent one idea, and no one will copy it all.

Jizhou also had a special military password before, and it could not be said that it was not secret, but unfortunately, the adaptability of this password was too poor, as long as someone who knew the password leaked out, there would be no secret at all.

The reason why Zhang Jaw was played around by Wang Yu and sat in the city was because of the leakage of Jizhou's military code. Tian Feng didn't seem to do anything in this battle, but in fact, he played a serious role.

suffered such a big loss, Zhang Jaw was not unconvinced, but as a famous general in the world, it was impossible for him not to reflect. What should I do if I encounter a similar situation in the future?

When he asked Wang Yu for advice on this question, Wang Yu casually gave him the password used in the Qingzhou army, and at first glance, Zhang Jaw was shocked.

The code used in the Qingzhou army is not complicated, but if you want to decipher, it is difficult to climb to the sky. According to the concept of Yin Fu, Wang Yu listed forty situations that could be encountered in the military, and coded them separately.

Before the general and his troops accept the battle order and set off, Wang Yu will agree with him to write a poem and song with four crosses as the decoding key. The poem must not be repeated, and a password with the above forty phrases is given.

Each word in the poem corresponds to a phrase, and the order of the phrases is improvised and random before the battle, and the password is only kept by a very small number of high-ranking generals on both sides of the communication, during the battle. The front and rear parties will communicate according to the password.

For example, you can use the "Guan Ju" in the Book of Poetry as a decoding key, Guan Guan Ju Dove, in the River Island, My Fair Lady......

If the army is running out of food in the battle and needs to be replenished, the forward general will find out the code of "please ask for food" from the password, if it is ninth. And the ninth character in "Guan Ju" is "窈". So the general asked the grain to write the word "窈" into an ordinary official document and put a seal on the word.

After receiving this official in the rear, they found out the word "窈" with a seal and learned that the word "窈" was ranked ninth in the poem that was temporarily agreed. Compare the order on the password, and you will know the information ahead.

Even if this method is leaked, it is in vain not knowing the verses and key order agreed upon by both parties in advance. Especially in the Qingzhou Army, Wang Yu, the lord, will throw a few poems out from time to time. Due to the delay in communication, Qingzhou is often well known. The outside world may not hear much about it.

If you take these verses as a code, who can accurately decipher them? If Jizhou had used this kind of password before, Wang Yu's false information would have confused Zhang Jaw at best, and he would soon see through his scheme.

In this regard, Zhang Jaw is also convinced.

Military superiority and disadvantage are not just a contest of more soldiers and fewer soldiers, but an all-round contest brought together by countless details. Although Jizhou has a lot of soldiers, horses, money and food, it lags behind Qingzhou in terms of war concept and strategy, and it is not unjust to lose this battle.

For Wang Yu, he was already shocked, but he also admired Xu Shu, who was directly involved in this work, even if it was only an auxiliary role, and he didn't think about the other party's age at all.

In fact, whether it is Zhang Jaw or Xu Shu, they don't know that this password is not Wang Yu's originality, this is actually the invention of Zeng Gongliang in the Song Dynasty, and Wang Yu just used it.

The military codes used in modern armies are usually Western-style methods, and Wang Yu has no intention of popularizing Western alphabets, and he also feels that there is no need to make it so complicated. Although he did not study much history, he knew a lot about the history of war, and if you think about it, you can borrow the wisdom of 'posterity'.

After discussing this topic for a while, the two had the feeling of seeing each other late, but it was getting late, and the army with open jaws had gone a little far, and the two had no choice but to say goodbye to each other.

Before leaving, Xu Shu suddenly asked: "Brother Junyi, you said earlier that it would be difficult to see you again if you missed it this time, I don't know why?" ”

Wang Yu was very clear about the division between military power and political power, and strictly forbade the generals to participate in local government affairs, and vice versa. In the eyes of Zang Ba, who has a tendency to secession, this is his refusal to let go of power, but the ideas of the generals in Qingzhou are different, but they don't have this feeling.

As long as there is no task in his body, Wang Yu never interferes with the movement between military generals, just like the sworn worship of Zhao Yun, Tai Shici, and Xu Shu. Therefore, Xu Shu asked this question.

"Well, Yuan Zhi, you may not know that this time, the lord will entrust you with a heavy responsibility, which will not only be very difficult, but also very long." Zhang Jaw said with a hint of amazement.

"Now?" The difficulty and time were filtered out by Xu Shu at once, he was just very curious, at this moment, what other heavy responsibilities did Qingzhou have with both risk and difficulty.

"Actually......" Before Zhang Jaw set off, Wang Yu had held a military meeting in the army, and he also knew about the matter in Hedong, so he briefly repeated it to Xu Shu at the moment.

Xu Shu's eyes lit up, there was no trace of fear on his face, and he laughed loudly: "I see, this matter really belongs to me." ”
