Zhang Fei showed his might in front of the battle, and even beheaded five Xianbei generals and captured one member, which had already made the Xianbei army frightened, and at this time, the Han army launched a full-line attack at the same time, where could they not be frightened and run wildly? As a result, the Xianbei army ignored the reprimands and commands of Qian Man and the chiefs, and retreated to the camp one after another.

Where can the Xianbei camp, which is only a few dozen steps wide, tolerate the crowding and pushing of 20,000 iron horsemen? Then a new chaos arose, and countless Xianbei iron horsemen crowded at the camp gate, unable to advance or retreat, and even Qianman and the chiefs of the various tribes were also trapped outside the camp, unable to move. Under the leadership of Guo Bin, Guan and Zhang, and Wang Yue, the soldiers of the Han family covered up and killed all the way, and the Xianbei soldiers rushed and panicked. Finally, the gate of the Xianbei camp collapsed in chaos, and the scene became more and more uncontrollable.

The drums in the Han army's formation became more and more urgent, and the sound of "Tongtongtong" was like a death knell, hitting the hearts of the Xianbei sergeants, urging them to retreat as soon as possible.

Seeing that the situation was already out of control, Qian Man drew his sword and put it across his neck when he was disheartened, and wanted to kill himself on the spot, but was stopped by his cronies. He said discouragedly: "Now that Da Dan doesn't know life and death, and the 30,000 army has collapsed to this point, I have the trust of my father Khan, what face does I have in the world?" ”

The subordinate said: "Don't be discouraged by the eldest prince, the Han people have a saying that if you stay in the green mountains, you are not afraid of no firewood." And leave a useful body, and he will make a comeback one day, and it is still unknown. ”

So, under the guard of a group of cronies, Qianman bypassed the camp and hurried north.

As soon as Qianman Shuaiqi ran, it seemed that a scoop of cold water was added to the boiling oil pot, and the Xianbei army exploded in an instant. Both the generals and the non-commissioned officers were not even in the mood to organize resistance, and the army threw away their armor, or passed through the camp, or bypassed the Xianbei camp, and fled north one after another.

Guan Zhang and the two each led a thousand horsemen to the north to quickly pursue, covering all the way, while Guo Da led an army of 5,000 to march slowly, on the way to deter prisoners, collect ordnance, and appease the fleeing Xianbei horses, so it was a busy job. On the one hand, Guo Bin led people to collect scattered horses around the Xianbei camp and clean up the battlefield, and on the other hand, he took Su Shuang and Wang Yue into the Xianbei camp to collect the spoils of war and check the materials. Although Su Shuang had nothing to do on the battlefield, he was able to check the materials, supply logistics and other matters, but he was able to capture him, so that Guo Bin could only watch from the sidelines.

Looking at Su Shuang, who was sitting in Qianman's previous tent and crackling with a large number of young people and making calculations with great confidence, his mentality and temperament seemed to be a different person, which was very different from the gentle and modest image on weekdays. Not only did Wang Yue open his mouth wide, looking incredulous, it was Guo Bin, but he also had to sigh: "The so-called hearing has a precedence, and there is a specialization in the art industry, and sure enough, everyone has their place!" Even chickens and dogs can save people's lives, not to mention professionals like Zhang Shiping and Su Shuang, who are very good at doing business. Unlike everyone at this time, Guo Bin, who is from modern times, naturally has no prejudice against businessmen.

However, when it comes to the abacus in Su's hands, I have to thank Guo Bin.

Before the advent of the abacus, people counted numbers and planned things, and the use of them was called "arithmetic". With the development of production, calculations became more and more complex, and the use of small wooden sticks for calculations was limited, so people invented a more advanced calculation tool called the abacus.

It is impossible to find out who invented the abacus, but its use is likely to have been very early. Regarding the origin of the abacus, it can be traced back to 600 B.C., and it is said that there was an "abacus" in China at that time. The ancients strung 10 abacus beads into a group, arranged them in groups, put them into the frame, and then quickly dialed the abacus beads to calculate.

In the Eastern Han Dynasty mathematician Xu Yue's "Records of Mathematics", there is a saying that "the abacus controls the four times, and the longitude and latitude are three talents". Zhen Luan in the Northern Zhou Dynasty once introduced the abacus as follows: "The stereotype is three points, each with five beads, the upper bead and the lower four beads abacus color different, the upper color of the pearl is five, and the lower four beads are each one." ”

It can be seen that the use of the abacus at this time has already taken the rudimentary form of the abacus in later generations, and at least the rule that the upper one is against the lower five already exists. It was only in the Northern Song Dynasty that after the use of abacus gradually matured, abacus gradually replaced abacus and gradually became popular in the world.

In order to improve the calculation method at this time, and for his own convenience, Guo Bin initially popularized Arabic numerals and vertical formulas for simple addition, subtraction, multiplication and division algorithms in the Fulong Villa School, and the improvement of this calculation method was undoubtedly sought after by Zhang Shiping and Su Shuang. A businessman who always maintains a great enthusiasm for new things, not to mention this extremely practical method of counting and calculating business calculations that greatly simplifies it?

Later, Guo Bin talked about abacus in a casual conversation with Sima Hui, which made this great master with extremely high academic attainments very interested. So, at Sima Hui's strong request, Guo Bin ordered someone to make a few abacus.

When Guo Bin was in elementary school, he was about the second grade, and there was still an abacus course in the math class. Of course, this kind of course is designed to teach students to use the abacus, an "ancient" calculation tool, but it does not have the luxury of "training child prodigies". Although Guo Bin didn't learn and didn't know how to do it, after holding it back for a few days, although the simple algorithm of addition, subtraction, multiplication and division was finally held back, he couldn't do anything about the mantra used by the abacus.

However, even so, the emergence of the abacus also caused a sensation in Yangzhai County. Immediately, this calculation tool was valued by Xu Shu, who had been serving as Zhao Yun's deputy and in charge of the clerical work in the county government, and quickly spread to the county government. Since then, there have been a large number of masters in the use of abacus in the county government, and in the future, whether it is counting the registered population every year, collecting taxes, distributing military rations, and counting materials, the abacus has played a very important role.

With Guo Bin's repeated deepening of the development of the three cities outside the Saiwai, the abacus also came to the Saiwai with the students who had just graduated from Yangzhai County High School and were assigned to the three cities outside the Saiwai and played a huge role in the trading bank. And Zhang Shiping and Su Shuang, who are the directors of the three cities outside the Saiwai, have long tasted the sweetness of the new calculation method that has been circulated in Fulong Villa, and now they have seen the abacus, a very convenient and fast calculation instrument, where is the reason to let go? Therefore, they organized a large number of young men under their command to work hard to learn the bead algorithm under the students of Yangzhai County.

With the passage of time, Zhang Shiping and Su Shuang even set up their own small teams, and they had a group of abacus masters under them, who were specially used for the inspection of materials in the three cities outside the Saiwai. The reason why this battle with Xianbei Dadan Yu Helian was able to achieve such a big victory was inseparable from the rapid dispatch of materials. The reason why the materials can be transported quickly is closely related to the number of mules and horses in the three cities outside the Saiwai, and the group of abacus masters under Zhang Shiping and Su can be regarded as making great contributions. Even Xi Zhicai couldn't stop praising them, and he was determined to set up such a team after returning to Yangzhai.

Yes, the role of highly qualified professional accountants in the war is extremely difficult for ordinary people to notice, but no one can erase their tremendous contributions. And now the spoils in the Xianbei camp are counted as "professional counterparts", and they are used to the fullest.

At about two or three o'clock in the afternoon, I heard the neighing of horses from people outside the tent, Guo Bin hurriedly bowed his head and went out of the tent, and sure enough, Guan Zhang and the others led the army to triumph. For this battle, Guo Bin had already known that it was too difficult and extremely unrealistic to annihilate the main force of Xianbei. Xianbei people are fast, and their riding skills are better than those of the Central Plains, so it is not difficult to defeat them, but if you want to keep them, you have to have an army of 100,000 and tricks to do it. This method, which greatly increases the cost of war and has an extremely high risk coefficient, is certainly not within the scope of Guo Bin's consideration. His goal in this battle was to repel the main force of the Xianbei army and annihilate its living forces as much as possible. So far, the results have been remarkable.

Zhang Fei made a great contribution in front of the two armies today, showing his face greatly, and he walked with the sound of wind at this time. I saw that the side of his horse was full of Xianbei heads with helmets, and while talking and laughing loudly with Guan Yu, he came to the big tent of the Chinese army, looking at the appearance of the heads, they were obviously all generals in the Xianbei army.

Seeing Guo Bin out of the account, Zhang Fei stopped talking, hurriedly rolled the saddle and dismounted with Guan Yu, and at the same time saluted: "Guan Yu (Zhang Fei) was ordered to pursue the enemy, turned back at thirty miles, and came to pay the order!" ”

Guo Bin hurriedly stepped forward, stretched out his hands to support the two, and said with a smile: "Yesterday, Li Yunchang has killed Helian, and today Yide has killed the enemy in front of the battle and made meritorious contributions, which makes me so hot!" ”

With that, the three of them looked at each other and laughed.

Fighting against the Xianbei army today, Guo Bin didn't want to have a good time, but since Xi Zhicai was not there, the 20,000 army needed him to sit in the Chinese army and preside over the overall situation. Moreover, cultivating Zhang Fei today is also a plan he has already drawn up. Yesterday, Guan Yu killed He Lian and made a great contribution, so Zhang Fei must be picked up again today. It's not that he doesn't trust Guan Yu, but that all those who engage in politics will follow the principle of balance. Guan Yu and Zhang Fei contain each other, and Guo Bin coordinates in the middle, this is the way a mature group should operate, otherwise after a long time, it will inevitably be chaotic.

Guan Yu in history is loyal and unparalleled, which is admired by the world. How much of this is true and how much of it is made up by posterity, it doesn't matter for the time being. It was determined that even if he held a lot of power in another day, Guan Yu would not have the idea of betraying Guo Bin, but once the situation was pressing, he would have to do many things against his will. Don't you hear about the Song Taizu Chen Qiao mutiny? Isn't Zhao Kuangyin a loyal minister of Chai Shizong of the Later Zhou Dynasty?

Therefore, Guo Bin's action is to fundamentally put an end to this kind of chaos and avoid many unnecessary internal friction arrangements. This arrangement did not come from his own intentions, but it reflected his gradual political maturity. Although this is Guo Bin's personal sorrow, it is a blessing for the entire interest group headed by Guo Bin.

When the three of them were enthusiastically exchanging the gains and losses of this battle, as well as how Guan and Zhang arranged for the cavalry to continue to track the enemy and investigate the enemy's situation, Su Shuang walked over to them with a few pieces of paper.

When Guo Bin saw it, his heart moved, and he hurriedly pulled the two of them to greet Su Shuang, and said, "Haha, the loot has been counted!" Let's see what's good this time! ”
