In the fourth year of Yongjia, in May, AD 310.

As soon as the summer began, Ran Long led 3,000 Qingzhou soldiers to defeat the invading Goguryeo barbarians several times in Lelang County. He beheaded more than 3,000 barbarians such as Goguryeo and Jeong, and captured more than 6,000 people of various tribes, including Goguryeo ambassadors, eldest brothers, Wu Zhuo and other officials and generals. The King of Goguryeo led only more than 1,000 people to flee north of Baishan.

After this battle, the reputation of the Lelang County soldiers was completely launched. The Baekje King, who was next to the Defang County, had already gathered a large army and was preparing to take advantage of Goguryeo to invade the two counties and get a bargain behind. After seeing the victory or defeat, he quickly sent someone to send a letter to Lelang Prefect Zhang Tong, saying that he wanted to assist Zhang Prefect Zhang to block the people of Goguryeo.

After nearly two consecutive months of war, the three thousand Qingzhou troops under Ran Long were exhausted. After learning about this situation, Liu Yu ordered Ran Long to take charge of Lelang County. On the one hand, he repaired it and prepared to return to Qingzhou. On the other hand, he also helped Zhang Tong, the prefect of the two counties, establish his prestige, so that he could rule the scholars of the two counties.

Originally, these Baekje people were ready to move, but after the summer began, it was no longer the best time to use troops. Moreover, Baekje people were relatively weak and did not have much threat.

Therefore, Ran Long and Zhang Tong finally accepted the support of the Baekje Land King, and gave them the requirement that as long as they were offered some Mahan slaves every once in a while, they could not blame the past for the past.

At the same time, the thousands of slaves captured during this period were also transported to Donglai County by Qingzhou naval army ships. After these slaves were identified, they were sent to various islands to dig out struvites. Except for some of the "temporary conscious people" who were the leaders of the slaves and assisted the Qingzhou army in custody and management, the fate of the other slaves was already destined when they set foot on those islands.

These islands filled with poisonous snakes, insects and birds are their last destination. Except for a few "knowing the times", most Goguryeo, Feng and Wuji slaves will continue to work to dig out struvites used in the fat fields of Qingzhou until they die of exhaustion and death on these islands.

"Yuanchang, let's leave."

Lelang Prefect Zhang Tong was leading the powerful sect leaders of two counties to bid farewell to Ran Long, who was about to board the boat and return to Qingzhou.

"Mr. Zhang, we will have a date later."

Ran Long bowed and then boarded the Qingzhou Navy's Six-Cross Boat.

With Ran Long's last boarding the ship, the Qingzhou Navy's ship rose sails and slowly accelerated its sail towards the west with the help of the east wind.

Looking at the Qingzhou fleet gradually fading away, Zhang Tong felt mixed feelings.

This time, the three thousand Qingzhou soldiers suddenly appeared instantly reversed the situation where the Goguryeo people wanted to plunder Lelang County, and wiped out thousands of Goguryeo soldiers and thousands of savages in one fell swoop. Basically, the Goguryeo people did not dare to go south to harass him within one or two years before they figured out the situation in Lelang County. It can be said that after this battle, Zhang Tong instantly gained unprecedented prestige and power, and the tyrants of the two counties are now quite obedient to him.

However, Zhang Tong knew that all this was because of the support of the Qingzhou Army. If there were no Qingzhou Army, he would have been plundered by the Goguryeo people this year, which would delay the farming work. In winter, he would have to go through the valleys and hunt with his subordinates for a living.

Therefore, when the Qingzhou Water Army Supervisor Yi Zhong brought the oral message from the Qingzhou Governor Liu Yu and was willing to appoint Zhang Tong as the general of Zhengdong to attack the prisoners and supervise him, Zhang Tong hesitated for a moment and agreed.

In this way, Liu Yu, as General Zhengdong and Zhang Tong also served as General Zhengdong to attack the enemy and supervise him, expressed his attitude of surrendering.

Although the prefect of Lelang, who was appointed by Zhang Tong, was under the jurisdiction of the Pingzhou Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Governor's Gover

Although Zhang Tong felt that the official position of seeking the prisoners and supervising was a bit inappropriate, and through his conversation with Ran Long, he had concluded that Liu Yu must have a lot of intentions, but now the problem of Lelang and the two counties in the two counties is how to survive, rather than these short-selling righteousness.

Just when Ran Long led the Qingzhou army to board the ship and began to return to Qingzhou, the spring plowing and summer planting that Liu Yu was very concerned about was basically completed.

The drought that Liu Yu was worried about did indeed happen, but most of the situation in Qingzhou is not that serious, and it is not as serious as Bingzhou and Jizhou. Especially after the large-scale use of water-lifting windmills in various counties and counties, some drought has also been alleviated.

Through the previous spring farming inspection, Liu Yu took advantage of this opportunity to basically understand the situation in Qingzhou.

Today, Liu Yu occupied a county in Qingzhou, with 115,000 registered households and a population of about 700,000. In the same area, the population is only about 10% of the same area as the onion province in later generations.

Among them are ordinary households with 72,000 households, 3,000 Qihuo soldiers placed in Jibei County, 9,000 refugees in Yanzhou and Jizhou, and 30,000 military soldiers stationed in each county.

The number of these populations has increased significantly compared with the previous ones. This is not because of the reproduction of the population, but because of several military incidents in Qingzhou, Liu Yu took the opportunity to eradicate some powerful people and release many hidden populations.

Although the number of registered people in Qingzhou is now 700,000, in fact, according to the speculations of Liu Yu and Hua Xiu, the number of hidden household registrations of local tyrants in Qingzhou can be as many as 300,000 to 400,000, which is definitely an eye-catching number.

Liu Yu now controls a population of 700,000 and supports 20,000 combat soldiers and 30,000 auxiliary soldiers, which has already made him feel very troubled.

When Liu Yu thought of the fact that Shu Han had supported nearly 100,000 soldiers in history with a population of one million, he couldn't help but admire the terrifying 10 to one militia ratio.

However, Liu Yu is still confident about the plan to expand the Qingzhou army to 30,000 armored soldiers and 50,000 auxiliary soldiers next year.

Today, Qingzhou has a total of about 6 million mu of land that can collect taxes and provide for military soldiers. According to the yield of at least 200 kilograms of millet per mu, which is two stones, there will be 12 million stones that year. According to the total output, the tax collection is enough to support tens of thousands of soldiers.

Of course, this only solves the problem of eating. If there is a serious famine, there will still be variables. After all, at this late Western Jin Dynasty, all kinds of natural disasters were the least lacking.

In order to deal with the possible food crisis, Liu Yu has strictly controlled the number of craftsmen, leaving only craftsmen who smelted iron, salt, porcelain, preparation and copper. After all, the more craftsmen they occupied, the fewer farmers would farm and harvest grain.

Especially the huge smelting steel test, in addition to craftsmen and apprentices, a large amount of labor is needed to complete a series of preparations such as logging, charcoal burning, transportation, and mining. After several tests failed, Liu Yu had to reduce the allocation of materials and planned to wait until his spare time in autumn and winter to increase the intensity of the test.

Moreover, after these complicated experiments and trial productions, Liu Yu has discovered an important problem.

These craftsmen are very good at practical operations, but they find it difficult to understand some of the suggestions and methods put forward by Liu Yu.

After all, the experience and knowledge of these craftsmen have been obtained through word of mouth and self-examination and summary in decades of practice, which is very different from the knowledge Liu Yu systematically learned from books.

During frequent communication, Liu Yu discovered that it was often those younger craftsmen or apprentices who could understand his various suggestions and methods earlier, while those older and more experienced craftsmen often realized it later, and even ended up not being able to do so.

As the saying goes, "It is better to teach people how to fish than to teach people how to fish." Liu Yu simply selected the group of young people with the strongest learning ability from all the craftsmen in Qingzhou, starting with the most basic mathematics, chemistry, and physics.

At the beginning, Liu Yu also taught in person, but when his clerk completed the basic mathematics, physics, chemistry and other books compiled by Liu Yu orally, Liu Yu directly appointed the clerk who compiled these books to teach the teachers this knowledge.

After all, teaching to craftsmen who are basically illiterate is a very life-saving thing.

Only when encountering problems that even the clerks and lecturers don’t understand, Liu Yu will take action personally.

Of course, the learning of this knowledge is carried out at night, and in order to ensure the quality of learning, the most commonly used tool in these classes is the rattan used to hit people.

When Liu Yu saw a simple angle calculation, the difference between carbon quantity and specific gravity density calculation of such small problems, can dozens of skilled craftsmen be discouraged. Even if Liu Yu knew some knowledge that was ahead of thousands of years, it would be difficult to complete some systematic innovations and changes in this case.

Liu Yu knew that he was too anxious about these things, so he could only use the method of "carrot and stick" to make these craftsmen with high hopes learn quickly.

Linzi City, within the Qingzhou Governor’s residence.

Liu Yu looked at the report he had just sent, and in addition to the production and training reports of the county and county and military soldiers, he was competing to cry for the lack of supplies, either agricultural tools, livestock, or weapons, armor and bows and arrows.

The demands of tens of thousands of officials and soldiers were like bottomless black holes that swallowed up Liu Yu's pitiful treasury storage.

But at this moment, the various caravans in Qingzhou were operating extremely bleak, and even the extremely hard currency of salt, white porcelain and other goods were in a backlog.

The reason for this situation was that the situation in the world was even more chaotic at this time. Except for Youzhou controlled by Wang Jun and half of Jizhou, the rest of the southern part of Jizhou, Sili, Yuzhou, Xuzhou, and Yangzhou, all kinds of barbarians, refugees, and rebel generals broke out.

In such a messy situation, even normal farming can no longer be carried out, let alone commercial actions.

Under this situation, although many refugees have flocked to Qingzhou, the more intuitive impact is that the various outputs in Qingzhou are no longer exchanged for other materials needed.

It can be said that due to war in the Central Plains, there was no normal commercial activity. Apart from food and weapons, nothing could be called hard currency.

In this way, the supply of medicinal materials, fine iron, copper ingots and other goods needed by Qingzhou will be immediately cut off.

Faced with this situation, Liu Yu couldn't help but sigh again. No wonder the history teachers in the past always said in class that long-term wars in ancient times often caused a regression in productivity. Nowadays, even the "barter" business is cut off, and it is abnormal to have no regression in productivity.

"Haha, if this continues, it will be a powerful army and will go out to seize the counties that produce goods." Liu Yu couldn't help but smile bitterly. If Qingzhou's technology achieves leapfrog development in the future, it will really have to be sold out to grab territory, even if there are endless troubles attached to these lands.

"Husband, what did you say?"

When he heard Liu Yu muttering to himself, Wang Ze, who was sorting out the book case next to him, did not hear it clearly, but asked with his big eyes.

"It's okay, I just feel a little emotional when I see these nns everywhere."

As he said that, Liu Yu gently stroked Wang Ze with some pity.

Now Wang Ze is not only responsible for the affairs of the inner house, but also has some responsibilities for dealing with Liu Yu's internal affairs.

During the Western Jin Dynasty, it was an era when the high-ranking families often served as prominent people. Liu Yu was basically unaware of who was the high-ranking gentry. The king was born in the Wang family in Taiyuan and knew much more about these families than Liu Yu.

So, Liu Yu was arrested in the study and became a temporary administrative secretary.

The little girl Wang Ze was very happy about Liu Yu's intimate behavior, and felt that her husband really loved her.

Wang Ze thought that before she married Liu Yu, she thought Liu Yu was a tiger, wolf robber who ran out of Donglai Mountain, and she cried several times. If she hadn't been afraid of marrying the Hu people from the Duan tribe like her sixth sister and seventh sister, she wouldn't have wanted to.

But unexpectedly, after marrying to Qingzhou, her husband was not only young, but also loved her very much. She felt that she was much happier than the elder sister who married Zao Song and Zaotai.

When Wang Ze thought of this, he remembered the maid around him, and the rumors he had told him about, saying that Liu Yu was an ambitious person who rebelled against the king, and that the emperor of Luojing would sooner or later come to Qingzhou to attack the traitor Liu Yu.

Wang Ze sneered contemptuously in his heart. With her recent knowledge of reading official documents and news reports, and Liu Yu talked to her from time to time, she knew that Qingzhou is now a rare place of peace in the world, and Luojing is already in danger, and the emperor of Luoyang may be unable to protect himself.

If that time really comes, at worst, she will be a rebel with Liu Yu.

Liu Yu handled some documents and finally decided to take the little Loli Wang Ze to see the young guards practice.

According to the schedule, today's so-called exercise is actually playing polo. After watching it twice, the little Loli Wang became obsessed with this passionate and violent sport. She always had to go to every polo exercise every five days.

Sure enough, Wang Ze was happy after hearing this and went to change into Hu's clothes and riding horse clothes.

At this time, a soldier from the guard came to Liu Yu and reported something.

After listening to it, the expression on Liu Yu's face became surprised instantly.

"What did you say? The beggars were killed by the soldiers of Taishan County?"
