Regarding Yuan Shu, Guo Peng is actually not worried.

Guo Peng's spies discovered that Yuan Shu had recently been attacking cities everywhere to expand his sphere of influence, and he was also looting grain and grass everywhere, which triggered a serious local backlash.

For example, Lu Kang, the Taishou of Lujiang County, erected an anti-flag to resist Yuan Shu, which made Yuan Shu furious, and sent Sun Ce, the captain of Huaiyi, to lead 20,000 soldiers and horses to attack Lujiang County.

Based on this, Chen Gong believed that Yuan Shu would not have the strength to intervene in the war in the north, because in addition to the war in Lujiang County, Yuan Shu also caused big trouble.

He deceived Ma Ripan's talisman and put Ma Riyan under house arrest, and then simply killed Ma Ripan.

After Ma Riyan died, it triggered a strong reaction from celebrities and scholars from all over the world.

Who is Ma Ripan?

He is a member of the Fufeng Ma clan, a grandson of the master of scripture Ma Rong, the most famous person in the Ma family, and a famous person in the world.

The news that Yuan Shu was under house arrest and killed him has spread, and everyone who knows about it is extremely dissatisfied with Yuan Shu, thinking that he has a heart of disobedience, and actually killed the envoys of the court under house arrest.

The Chang'an court will inevitably take countermeasures accordingly.

Chen Gong boldly deduced that before, the Chang'an Imperial Court did not give Yuan Shu a local official position, maybe he just kept a hand, but Yuan Shu was too faceless, and the Chang'an Imperial Court was very likely to confront him.

If you don't give me face, I won't give you the lining, and I will send someone to fight with you.

Chen Gong believes that the Chang'an Imperial Court will send people to Yangzhou to deal with Yuan Shu, and it is very likely that Yuan's postoperative courtyard will catch fire, and it will not be easy to wipe his butt by himself, let alone intervene in Guo Peng.

Guo Peng thinks what Chen Gong said is very reasonable.

Then next, among the princes, there is only one Tao Qian left.

The territory is safe and sound, the people of Xuzhou live peacefully, there are no foreign enemies, there are no internal worries, Xuzhou is full of household registration, and if it is mobilized over time, it is not a problem to bring 100,000 armor.

And Tao Qian also had some festivals with Guo Peng.

The first holiday is the problem of the Yellow Turbans.

At the beginning, Tao Qian drove the Yellow Turban Army to the territory of Guo Peng, who was plagued by the calamity of Qingzhou, and Guo Peng's climate used his own way to govern his body, and he took revenge on Tao Qian once, and the unhappiness between the two is traceable.

The second festival is that Guo Peng served as the general of Zhendong, and Tao Qian served as the general of Andong.

Guo Peng is young and has not held official positions for a long time, while Tao Qian has deep qualifications and is old, has held official positions in various places, has rich experience, and is one of the representatives of the old bureaucrats.

Let him be Guo Peng's assistant, can he be willing?

The old guy must have been holding his breath and not coming out.

Then Guo Peng also co-opted Mi Shi, the richest man in Xuzhou, to do his own assistance, and let Mi Zhu be an official under his command, and now he has achieved the position of Jinan State Minister, and also gave his sister to Guo Peng as a concubine, obviously determined to take refuge in Guo Peng.

As the richest family in Xuzhou, the Mi family not only has a large amount of land and industry, but also has a considerable number of private troops, and the force cannot be underestimated.

This is equivalent to planting a time bomb in Tao Qian's sphere of influence, which may explode at any time, as long as Guo Peng has an idea.

Now it is Guo Peng who sent troops to suppress, Xiahou Yuan led the army to garrison at the border of Xuzhou, deterring Xuzhou all the year round, and preventing Tao Qian from making a move against the Mi family, once Guo Peng went north to attack Yuan Shao, Tao Qian was very likely to make a move against the Mi family.

This old guy is not a simple commodity, not only cunning, but also rigid and bold, but Guo Pengjun is powerful, he is really afraid, so he doesn't dare to act rashly.

Therefore, the strategists collectively believed that Tao Qian was the biggest hidden danger for Guo Peng to go north to crusade against Yuan Shao, and if necessary, they could send troops to move closer to Xuzhou to deter Tao Qian and make Tao Qian dare not act rashly.

Guo Peng agreed with this opinion, so he ordered Xiahou Yuan, the commander of Poyu and the garrison of Donglai County, to increase the number of troops to 5,000, and to increase the garrison of Mount Tai in Taishan County, and ordered the lieutenant of Zhongwu to lead 5,000 troops to serve as the garrison of Mount Tai, and cooperate with Xiahou Yuan to deter Tao Qian.

He took office after the army officially launched the Northern Expedition.

After making arrangements for Tao Qianhe, Guo Peng could finally make a complete assessment of Yuan Shao and Zhang Yang's forces, and discuss how many troops should be sent to fight them.

In this way, the calculation of the required grain and grass, auxiliary soldiers and civilians, as well as various transportation equipment, can begin.

It is a matter of food, clothing, shelter and transportation of the army, and these must be accurately calculated, and if the calculation is wrong, it will deal a devastating blow to the army's conquest.

Guo Peng has long cultivated mathematical and statistical talents in his own estate, specially trained their mathematical ability, and continuously increased the training of talents in this area to cope with the growing shortage of mathematical talents.

Thanks to the early start, Guo Peng can now arrange a computing army of 500 people to be put into the administrative department, and in wartime, he can also mobilize manpower to gather and calculate the various data put forward by the strategists and draw conclusions about the data.

The so-called war, in fact, involves the calculation and use of a lot of data, which is absolutely inseparable from mathematics, and any mistake in calculation will bring disastrous consequences to the war.

The number of troops and horses dispatched, the number of rations, the number of horses, the number of ordnance, the average daily consumption of various materials, and the consumption of transportation to the front, etc., all require precise calculations to draw the most reliable conclusions.

To this end, Guo Peng introduced the concept of Arabic numerals, and taught them the rules of the four operations and the production of statistical charts, simplifying the cumbersome operation process, reducing their workload, and improving accuracy.

Everything is inseparable from mathematics, and Guo Peng has deep feelings in this regard.

He was also deeply touched by the fact that having a qualified math team and obtaining accurate data could help the war and agricultural production.

For example, after intelligence exploration and assessment of the actual situation of Zhang Yang's Hanoi County forces, through the accurate calculation of the calculation team, it was determined that Zhang Yang could not drive an army of more than 10,000 people to fight despite his best efforts.

Even if he starts preparing now and gives him half a year to mobilize and prepare grain and grass, with the current situation in Hanoi County, he can recruit more troops, but he can't get more food and grass and can't fight.

Zhang Yang, a small threat, only needs 10,000 teachers to directly attack his ruling core.

Han Hao also said that he could persuade some counties to surrender on their own initiative to avoid the pain of being attacked by the army.

Zhang Yang's threat was further downgraded.

And according to the important information of the secret agents, the relationship between Zhang Yang and the generals under his command is not close, and even a little stiff, which may be a breakthrough point.

Compared with the simple Zhang Yang, Yuan Shao is slightly more complicated.

According to the accurate calculation data of the calculation team, there are as many as one million households in Jizhou.

At the beginning, Guo Peng defeated Lu Yi and plundered the population of Qinghe Kingdom and Bohai County, and obtained about 40,000 households, which failed to shake the foundation of Jizhou.

Yuan Shao expanded his army in order to deal with Gongsun Zhan, and now there are as many as 50,000 troops that can be mobilized under his command, about 10,000 elite standing troops, and the remaining more than 40,000 are miscellaneous armies.

The so-called 100,000 with armor is just a big statement, and it can't be true.

Although it is difficult to supply these miscellaneous armies with military rations now, when they need it, Yuan Shao will give them more if he eats less.

During the war, it is not a problem to continue to forcibly recruit strong men and expand the army, and it is not a problem to bring 100,000 armor, but in the case of rampant conscription, it is possible to have tens of thousands, although basically there is no combat effectiveness.

This is Guo Peng's greatest advantage, that is, the combat effectiveness of the army.

"The army of the Ming Duke is carefully trained by the Ming Duke, there is no need to mobilize and call, and the order can be dispatched at any time, the number is as many as 70,000, in addition to the local garrison army, there are as many as 50,000 for mobilization, although Yuan Benchu also has an army that can be mobilized, but the elite level is not the same."

Chen Gong said excitedly: "No matter how much Yuan Benchu recruits more troops, in terms of weapons, armor, bows and crossbows, and even grain and grass, it cannot be compared with Ming Gong, with Ming Gong's mastery, it is more than enough to attack a Jizhou." ”
