After all, every time a war breaks out, in addition to the regular army to fight, there will be many young people who are called up to assist the army.

In this way, the labor force is conscripted and left, how can the remaining orphans and widows have the strength to open up fields and cultivate land in the local area, and how can they have food income if there is no one to open land and cultivate land?

There is no rootless source in the world, and if no one grows food, there will naturally be no income from food production.

This is also the reason why Cao Cao later vigorously promoted Tuntian, because if he did not Tuntian, the grain grown by the common people would not be enough for Cao Cao to use troops after paying taxes.

At the same time, the power of the scholars formed by many large local families and clans is not the type that does not pay much grain and taxes, but they occupy a large number of fields and dependent populations, and they are simply tarsal worms, but they can't easily do anything to them.

Therefore, Cao Cao often lacked food in the early stage of the Battle of Chibi, and had to implement the policy of tuntian, allowing the army soldiers to plant grain and grass for themselves to meet the needs of the army, until he pacified Yuan Shao in the north and unified the Central Plains, so that Cao Wei had enough foundation to fight against Eastern Wu and Western Shu in the later period of the Three Kingdoms.

And now, if Zhu Wei is preparing to carry out a military attack on the Central Plains in the future, then if he wants to obtain war materials to replenish in the Central Plains, I am afraid that it will not be an easy task, and it is estimated that all of them will depend on Zhu Wei's own food and material reserves.

Therefore, it is still a very necessary thing for Zhu Wei to increase his food reserves through the Three Kingdoms game system.

Of course, as far as Yuan Shu's situation is concerned, in addition to the impact of natural disasters, in fact, part of the reason is that Yuan Shu himself made man-made disasters, he said that the emperor's move to build the royal palace in Shouchun also required a large number of people's labor.

As a result, a large number of laborers in Huainan were originally pumped to build palaces, and there was not much labor to farm, which naturally greatly weakened the grain production on Yuan Shu's side.

Later, there was a drought, which made many fields unharvested, so naturally there was no food income, so Yuan Shu's own food reserves could only be consumed.

In this way, even if he has a solid family background, he can't withstand the consumption of Yuan Shu's own losers.

When Yuan Shu found out that the situation was wrong and was about to tighten the grain bag, he was a little overkill and became extremely stingy, and he didn't even feed his own army soldiers.

How can such a Yuan Shu not be defeated, it is simply self-defeating.

Anyway, now that Zhu Wei learned some intelligence information about Yuan Shu's army from Lei Bo and Chen Lan, it can be regarded as resolving some doubts in Zhu Wei's heart about the combat effectiveness of Yuan Shu's army.

However, although Zhu Wei easily obtained the county seat of Hefei, it can be regarded as opening the door to Shouchun for Zhu Wei's army, but then Zhu Wei has no plans to send troops to Shouchun immediately.

Zhu Wei divided part of his troops to Lu'an as soon as possible, preparing to attack the land of Lu'an first, and then contact the army of Mu Lan, Teng Yuyan, and Zhang Xiu who sent troops from Jiangxia.

In this way, all the troops of Zhu Wei on this expedition can be connected together, and they can obey Zhu Wei's military orders at any time.

As for Yuan Shu's side, although the foundation is rotten, after all, there are still fifteen or sixty thousand troops gathered in Shouchun, and at the same time, the current Yuan Shu must also have enough food to meet the needs of the military, even if his army's combat effectiveness is not good, it is still fifteen or sixty thousand people.

In addition, Shouchun, the capital city carefully built by Yuan Shu, although it consumed a lot of manpower, material resources, and financial resources of Yuan Shu, it was indeed built into a big city by Yuan Shu.

With the help of the tall and sturdy Shouchun City and 15 or 60,000 troops, it is enough for Yuan Shu to resist stubbornly and fight to the death, in the original history Cao Cao, Lu Bu, Liu Bei The three armies combined, and it took more than a month to fight, it can be seen that the offensive and defensive battles of Shouchun City are not so easy.

Zhu Wei didn't want to be bitten by Yuan Shu before he died, so he let himself be bitten out of thin air.

Therefore, Zhu Wei just quietly waited for the arrival of Cao Cao, Lu Bu, and Liu Bei, waiting for everyone to gather and make the last knife under the Yuan Shu that was coiled up like a poisonous snake.

Of course, there was not much force to guard Yuan Shu on the side of Lu'anguo, so Zhu Wei only sent Huang Zhong with about 12,000 Jiangdong battalions to capture the five counties of Liu, Tate, Anfeng, Anfeng, and Yangquan in Lu'anguo.

At this time, Zhu Wei also knew through the map of the Three Kingdoms game system that Mu Lan and Teng Yuyan's more than 10,000 light cavalry and Zhang Xiu's Liang Cavalry Camp had now entered the territory of Runan County, Yuzhou, and almost moved in the land of Xincai and Ruyin.

In fact, Mu Lan, Teng Yuyan, and Zhang Xiu, who were mainly cavalry, did not encounter much resistance from Jiangxia this time into the territory of Lujiang Qichun.

This Qichun County is located at the southern foot of Dabie Mountain, the terrain is high in the north and low in the south, the terrain is long and narrow, many mountains and mountains, only the southern area is close to Jiangxia, but the lake is scattered, and the port is vertical and horizontal.

Therefore, this Qichun County and the Huainan land controlled by Yuan Shu and the Lujiang County controlled by Liu Xun are mostly separated by the continuous Dabie Mountain, and it can be said that most of the areas in the county are still adjacent to Jiangxia, so Yuan Shu and Liu Xun do not have many troops on the side of Qichun County.

Of course, there is also not much local development and population base here, and it can only be regarded as a marginal place in some small counties and townships.

In this way, Mu Lan, Teng Yuyan, and Zhang Xiu combined at least more than 20,000 cavalry troops, and suddenly attacked along the official road of Qichun County, that is, they easily captured Qichun County in one day, and then took advantage of the situation to take the other two Yi County and Xunyang County, without any effort.

Next, they led the army to find the old official road here and entered the territory of Runan County in Yuzhou.

In the early days of the Yellow Turban Uprising, Bocai and Peng Tuo were the commanders of the Yellow Turban Army in Yuzhou, controlling Yingchuan, Runan, and Chen, with an army of more than 100,000 people, and became the main force of the Yellow Turban in the East.

At the beginning, Bo Cai led the Yellow Turban Army all the way to the west, and directly threatened Luoyang, the capital of the Eastern Han Dynasty, militarily.

Zhu Wei's cheap father, Zhu Jun, was ordered to fight during such a critical period, preparing to resist the threat of the Yellow Turban Army to the capital, but Zhu Jun was also defeated by Bocai's Yellow Turban Army at the beginning, and was besieged by the Yellow Turban Army in the land of Changshe.

Later, it was with the rescue of Huangfu Song that Zhu Jun could be regarded as taking a breath, and then the Han army used the plan of burning the Changshe to defeat Bocai's Yellow Turban Army in one fell swoop, so that Zhu Jun's Han army turned defeat into victory.

After the main force of the Yellow Turbans of Ke Bocai and Peng Tuo was exterminated, there were still many remnants of the Yellow Turbans in Runan and Yingchuan, and He Yi, Liu Pi, Huang Shao, He Man and others each had tens of thousands of troops, and they were still entrenched in the mountains of Yingchuan and Runan in Yuzhou.

Since then, Cao Cao has led his troops to clean up a lot of these Yellow Turban remnants, such as He Yi, Huang Shao, He Man and others have been killed, only Liu Pi and Gong Du seem to be still hiding in Runan County......
