After Liu Zheng reoccupied Guangling County, he immediately let Wu County's soldiers and horses cross the river, and then took over the defense measures of Guangling County in full.

In the next few days, Liu Zheng transferred 50,000 troops from Yangzhou and stationed them in Guangling County, in addition to his more than 10,000 cavalry, there were also the remnants of the Taishi Ci Department, and 10,000 soldiers and horses.

As well as some trolls.

Although Liu Zheng got the news that Lu Zhi quickly withdrew his troops from Qingzhou, returned to Xuzhou, and joined Liu Bei's men and horses, Lu Zhi did not continue to attack Liu Zheng at this time.

Both sides seem to have a tacit understanding and have temporarily suspended their troops.

This result was actually not what Lu Zhi wanted, when he returned to Xuzhou with 20,000 soldiers and horses, he actually wanted to fight Liu Zheng.

It's just that now he only has more than 40,000 soldiers and horses left, and Liu Zheng has 50,000 soldiers in Guangling, 40,000 against 50,000, and it is another siege battle, and Lu Zhi is not sure that he can defeat Liu Zheng.

He was even worried that Liu Zheng's soldiers and horses would take the initiative to attack, so Lu Zhi could only defend temporarily, and at the same time gather people around here as soon as possible.

After two months of fighting, Lu Zhi and Liu Zheng both suffered heavy losses, and even Yuan Shao, who attacked in Qingzhou, raised 70,000 troops to attack Qingzhou this time, and also lost more than 30,000 people, which made Yuan Shao himself suffer a heavy blow.

In addition, now that the time is in August, the weather is hot, and the people are impetuous, and everyone is unwilling to fight under the scorching sun.

Liu Zheng, who lost two states and counties, seems to have suffered a big loss, but Qingzhou and Xuzhou themselves do not have much tax revenue, and even a large part of them need Liu Zheng to allocate additional money, grain and grass to support.

Therefore, although Liu Zheng has regrets about the two lost territories, he can't hurt Liu Zheng's vitality, but makes Liu Zheng reflect on it, and makes Liu Zheng understand that he can't easily attack without the certainty of victory.

However, tens of thousands of horses have been lost, and the cost of family pensions for these tens of thousands of horses is not a small amount.

In addition, Liu Zheng's side was heavy on military spending, and the Mi family suffered heavy losses, and for a while, Liu Zheng's subordinates also had some economic crises.

Liu Zheng has not much money available.

Not only is there not enough money to pay for the families of the soldiers who died in the war, but even the money for recruiting new troops is also insufficient.

Fortunately, the trade in the north could not be carried out, and Liu Zheng opened the trade in the south some time ago, and he was able to transport some things from Funan to sell.

Coupled with some of the money looted from the royal family of Funanguo before, in a short period of time, Liu Zheng is not in short supply, but money is still very important, Liu Zheng must open up a new way to make money, otherwise it will not be long before he will still fall into a situation of lack of money.

With the death of Mi Zhu and the loss of Xuzhou, the Mijia caravan has temporarily fallen silent, although it is not enough to completely lose the business all of a sudden, but if you want to restore the glory of the past, it is not possible to do it in a short time.

After understanding that the people of the imperial court and Yuan Shao's men and horses had not changed for the time being, Liu Zheng was a little relieved and let his men and horses be stationed in Guangling, while he himself returned to Wu County.

Because of the lack of money, Liu Zheng had to find a way to get more money from other places, of course, this method, in fact, Liu Zheng had thought of it before.

He had some technology in his hands that was many years ahead of other places, such as papermaking and printing.

Almost a year ago, it was already tossed in the military academy of Liu Zheng's Yuzhang County, and at first it was only used by Liu Zheng for the use of these students under his command, but in order to make money, Liu Zheng felt that he could sell these printed books to people in other places.

The cost of a book is actually only a few dozen dollars, but selling it for hundreds or even thousands of dollars is not a problem.

The farther away from Liu Zheng's territory, the higher the selling price, so that Liu Zheng could harvest a lot of money from the hands of other princes.

Especially in Yuzhou, Sili area, these two places, there are too many families, and there are countless readers, if you can use these people in books, it is a big business.

And the book thing, it's not just a matter of buying one, what Analects, Tao Te Ching, Yellow Emperor's Neijing, Sun Tzu's Art of War and the like, print a few more copies, you can sell them to them.

Not only the readers will benefit from this, but even the poor people are also eager for books, so as long as Liu Zheng can sell these books, he will definitely be able to gain a lot of money.

Moreover, this time, Liu Zheng plans to vigorously develop his own business, and the goods he exports are not only books, but also some Sanliangye kept at home.

Although the Sanliangye in his family is not brewed much every time, it is not that Liu Zheng cannot brew on a large scale, but Liu Zheng wanted to maintain the uniqueness of Sanliangye before, so he has not expanded the production of Sanliangye.

Now he will not expand production, but will only take a part of it and sell it to other princes at a high price.

Through those generals under his command, Liu Zheng has learned that in this era, there are still many people who like Sanliangye.

As long as Liu Zheng takes out these wines and sells them, he will definitely be able to sell them for a good price.

Moreover, these wines only need to be exclusively for dignitaries, and the price will only be higher, making them appear to be sold in limited quantities.

It will definitely make people rush to it, and there is no market for it.

When he returned to Wu County, Liu Zheng immediately asked the people in the military academy to increase the printing of books, and at the same time brewed a new batch of Sanliangye wine.

Half a month later, a caravan was sent to sell these things directly to Luoyang.

These things were originally rare, and in order to make money, Liu Zheng took some ivory, pearls and other things from Funan to Luoyang for sale.

For a while, it was really sold at a high price, so that Liu Zheng's caravan looted a lot of money from Luoyang.

At the same time, Liu Zheng also spread the two things of books and wine to the entire Han Dynasty.

Of course, there is another reason why Lu Zhi and Liu Zheng will make a truce, that is, in August, when it is time for the grain to be harvested, everyone will temporarily suspend the army, and they also need to harvest the grain and grass.

Although there is no shortage of grain and grass on Liu Zheng's side, Lu Zhi and Yuan Shao's side are not rich, and the main reason why they attacked Liu Zheng is also to snatch grain and grass from Liu Zheng by the river.

The grain and grass in Qingzhou and Xuzhou have been planted before, and now they occupy Xuzhou and Qingzhou, and it is when the grain and grass are harvested that they can also harvest some grain and grass from these two places. It was used to cover last year's shortfall.

Especially Yuan Shao, who was already short of grain and grass, and his main purpose in snatching Qingzhou's mouth was to get grain from Qingzhou.
