Zhuge Liang was arranged by his eldest brother, so he had to go back to vacation obediently. In the last few days of the lunar month, as well as throughout the first month, I no longer ask about specific government affairs, at most I just listen to the news from the outside world, so that the information will not be disconnected for too long.

If you are really idle, then exercise and study the few volumes of biology and agronomy that the eldest brother picked out for him-

After the spring of the next year, Liu Beijun will pilot the new production method of raising and transplanting seedlings in Sheyang and Haixi. At this juncture, Zhuge Liang is willing to learn more agricultural knowledge and breeding thinking in later generations, which will definitely be beneficial and harmless for future work.

In the textbooks given by Zhuge Jin, of course, it is impossible to talk about "evolution" and "genetics", but it is still possible to give some simple common sense and thinking about breeding and selection. Zhuge Liang doesn't need to know the specific internal operation principle, he just needs to know the things at the application level.

In addition to these learning exercises, other serious things have their own big brother to temporarily coordinate the overall situation.

And those talents from the north, including Lu Yu, and the senior brothers who followed Lu Yu were like high temptations. There are also Xu Miao, Cheng Bing, Liu Xi, etc., Liu Bei took out the last period of Layue to give courtesy, find out everyone's endowment by the way, and then hand it over to Chen Qun to arrange specific errands.

After more than a year of training, Chen Qun has also transformed from a project organizer who organizes civil labor to a higher-level manager. His talent in employing people and organizing is gradually being discovered, and he can already help Liu Bei share some specific human resources co-ordination.

Liu Xi and Gao Qi are not suitable for specific work, but only for academic research, so provide them with conditions to bury themselves in research. Cheng Bing is slightly inferior to those two in terms of his own education, but he is good at preaching and solving doubts and transferring knowledge, so he will share some educational work.

Xu Miao is good at organizing the poor people to resume production, so let him share some of the work for relief, plus the resettlement of the people from the occupied areas of Yuan Shu.

In the end, there were more than 1,000 people brought back by Zhao Yun, hundreds of cavalry prisoners released by Yuan Shaojun's Gongsun Zhan cavalry, and nearly 1,000 pirate prisoners.

Liu Bei also personally inspected the circle, and then instructed Guan Yu and Zhao Yun to train urgently together to rectify discipline and morale. To ensure that it does not lag behind, those who should be incorporated into the cavalry will be incorporated into the cavalry, and those who should be incorporated into the naval army will be incorporated into the naval army.

After this wave of supplements, Liu Bei calculated that the number of cavalry troops under his command was close to 4,000, but the actual cavalry was still a little more than 2,000.

From the recovery of Zhao Yun last year to Zhuge Liang's trip to Hebei, he was able to pull hundreds of experienced cavalry every time. It's a pity that there is no matching war horse, so you can only use pack horses to form "mounted infantry" to make up the number.

This time the relationship between Yuan Tan and this line was opened, and Yuan Tan allowed Liu Bei's men to have "military access" along the coast of the Shandong Peninsula, and also provided transit and berthing supplies for maritime trade.

After the spring of the next year, when it is warmer, it may be possible for Mi Zhu to explore this sea route, establish trade with the warlord Gongsun Du of the Liaodong Peninsula, and buy war horses with sea ships.

After Guan Cheng was killed, it is estimated that there are still one or two thousand remnants of the chain of Shamen Islands between Shandong and Liaodong to disperse the pirates.

Tai Shici is a native of Donglai and is very familiar with the situation along the coast of Donglai. Moreover, Tai Shici went to Liaodong to avoid disasters for several years after committing crimes in his early years, and personally walked through this route from the Shandong Peninsula to the Liaodong Peninsula, and he was also very familiar with the situation in Liaodong.

Therefore, let Tai Shici escort open up the trade route, and it is absolutely a professional counterpart. After the Lujiang Battle is over in the summer of the following year, Tai Shici will be free and ready to deploy.

……

These trivial things are over, and it is basically almost the end of the month.

Liu Bei no longer called people, and the pace of all work in Guangling County slowed down.

However, because it takes time for information to be transmitted, even during the Chinese New Year, Liu Bei and Zhuge Jin will still receive some front-line military information from Chen Di or Qian Di every once in a while-

The battle information between the Cao army and the Yuan army of Chen County will always take about 20 days before it reaches Guangling, and the battle between the Lu Bu army and Yuan Shu in Qiandi is relatively fast, and it can be transmitted to Guangling in more than ten days, and the delay is relatively obvious.

According to the report, in the first half of the lunar month, the battle between Cao Cao and Yuan Shujun was the first to change. Chen County, which had been besieged by Cao Cao for more than two and a half months, finally ran out of food, the morale of the troops in Qiaorui in the city collapsed, and Yuan Shu's reinforcements could not be waited for outside.

On the seventh day of the lunar month, Qiao Rui had to try to organize a fairly resolute breakthrough, but unfortunately it was surrounded by Cao Cao himself, and there was a tragic bloody battle between the two sides, Qiao Rui suffered heavy casualties, the conflict did not come out, and thousands of charging soldiers collapsed and surrendered directly into the formation.

Qiao Rui had no choice but to retreat to Chen County, but the army's spirit could no longer be defended, and there was no food. Four days later, the guards of the west gate of Chen County chose to secretly contact Cao Jun, and were willing to sacrifice the gate to ask Cao Cao for pardon.

Cao Cao also agreed very simply, and finally at dawn on the thirteenth day of the lunar month, Cao's army entered the city from the inside, and after a day of melee, the battle ended completely.

During the two-and-a-half-month siege phase, about 27,800 Yuan troops were completely annihilated, including nearly 10,000 killed and wounded, thousands of those who fled while taking advantage of the chaos, and more than 15,000 surrendered prisoners.

Cao's army fled with bloody casualties, although the cumulative amount was not less than that of Yuan's army, after all, it was the besieging side. However, with the injection of a large number of surrendered troops, Cao's army has rebounded somewhat in numbers, and the total strength has increased by several thousand, but the quality of the troops has declined.

Many of the Yuan Shu troops who surrendered were temporarily mobilized and brought in by exhaustive fishing, and their quality was far inferior to the lost Cao army.

And Qiao Rui himself was also killed by Cao Jun in the final chaotic battle after Chen County's break, which was similar to the fate that Qiao Rui should have suffered - in the original history, Qiao Rui was killed by Cao Jun in the "Battle of Qiyang" in Chen County, and now it is nothing more than a change of county and was killed in Chen County.

After the Battle of Chenxian, Cao's army moved all its forces in Chenjun to the east and continued to besiege Kuxian, the last stronghold of Yuan's army in Chenjun.

Moreover, a large number of captives of the Yuan army who had just surrendered were conscripted to be used as cannon fodder to fill the moat and destroy the fortifications. He also took the opportunity to shout at Li Feng, the guard of the bitter county, telling him that the bridge was dead, Chen County was broken, and there was no hope for any longer defending, and wanted to prompt Li Feng to collapse as soon as possible and save some food for both sides.

After all, Cao's army was also very short of military rations, and Rao took the lead in implementing tuntian around Xudu last year, and sixty percent of the grain grown by the displaced people was confiscated and collected as official food, and it could not withstand the continuous siege and consumption of 50,000 troops from autumn to winter.

Cao Cao also really wanted to end the battle as soon as possible, so that he could save a little.

In order to prompt Li Feng to collapse as soon as possible, Cao Cao even changed the practice of besieging and dying in the previous months, and slightly withdrew an opening, pretending to encircle three and missing one.

But in fact, Cao's army had already laid an ambush on both sides of the vortex east of Kuxian, and if Li Fengzhen abandoned the city from this gap and broke through, he would also be intercepted and destroyed. And it is impossible for Yuan Jun to transport military food supplies into Kuxian County through the whirlpool, and if a large group of reinforcements and grain teams are approaching, Cao's army will also intercept and kill mercilessly.

Cao Cao only let Li Feng send a few messengers for help, in order not to startle the snake, so that it was also convenient to lure the snake out of the hole.

So within a few days, a large number of emergency documents were sent to Yuan Shu, so that Yuan Shu had to continue to use all his resources to increase his troops in the northwest. Even if he couldn't reinforce Ku County, Yuan Shu still had to consider how to consolidate the second line of defense after Chen County changed hands.

The eastern Henan Plain is a flat river, and the army can only be deployed along the key nodes of the main water network, and there is no danger at all to defend the others, and the troops occupied are naturally quite a lot.

……

Cao Cao made a major breakthrough, completely annihilating Qiao Rui and about to annihilate Li Feng, this news finally stimulated Lu Bu, and after Lu Bu and Chen Gong combined, he finally launched a decisive offensive against Yuan Shu between Liang and Yuan.

As mentioned earlier, Lü Bu sent Han Yin, Yuan Shu's envoy to Xu Du, to ask for beheading, which happened at the end of November. However, Lu Bu did not publicize it at that time, he just sent people to Xudu secretly.

After Cao Cao finished beheading, the news spread to Yuan Shu's ears normally, no matter what, it would be more than half of the lunar month, if Yuan Shu was angry and killed Qin Yilu as a reciprocal retaliation, it was estimated that it would be the second month of the lunar month.

Lu Bu is so low-key, of course, in order to win a sneak attack opportunity when he turns his face with Yuan Shu.

Therefore, after he heard that Cao Cao had killed Qiao Rui, which caused the Yuan army of Chenjun to be unable to withstand the pressure, which might cause Yuan Shu to tilt more troops towards the western front, he immediately seized this last time difference and launched a sneak attack on Yuan Shu's land.

As usual, Gao Shun was in charge of attacking the fortifications first, but Yuan Jun did not expect that Lu Bu was caught off guard, and he was captured at once two or three county towns with insufficient troops, such as Yu County and Qi County.

On the fifteenth day of the lunar month, the urgent news of Pegasus reached Shouchun, and Yuan Shu was furious when he heard the words - from Yuan Shu's point of view, he almost received Lu Bu's sudden sneak attack on the land with his back on the front and back feet, and then received Han Yin was sent by Lu Bu to Xu Du to ask for beheading.

Within a day or two, even under the impact of Lu Bu's betrayal and anger, Yuan Shu was so angry that he vomited blood and fell into a coma, but fortunately he was rescued by the medical officer.

Yuan Shu's temper is the most unbearable, and after waking up, he can't care about defending Cao Cao, and then adding troops to the rear of Kuxian to set up a second line of defense. Even ignoring Cao Cao's defeat of Chen County, he could go south to enter Runan County, the Yuan family's old nest.

Yuan Shu just completely lost his mind and ordered hoarsely: "Pull the newly recruited soldiers of Runan County and Huainan County, and all the soldiers who can mobilize field battles, to the land, and I want to drive the personal expedition and fight to the death with Lu Bu!" Swear to kill this unrighteous dog thief to thank the world! ”

This time, Yuan Shu's subordinate officials had a very unified opinion, whether it was Yan Xiang, who was slightly wise, or Yang Hong, who was greedy and despicable, they actually dissuaded him in unison:

"Your Majesty, no! Although Lu Bu is a hateful thief, he has no long-term plans, he just wants to take advantage of the fire to rob and get a vote, doesn't His Majesty know about him? The real threat is actually Cao Thief, and even Liu Bei.

If the soldiers and horses of Runan are also sent to reinforce other places, after the Cao army captures Kuxian, if a false shot is no longer sent east, but turned south, the place of His Majesty's ancestral home will be dangerous! And if the Huainan soldiers and horses are transferred, who will defend this Gyeonggi heavyland! ”

Yuan Shu insisted on going his own way: "No matter! Cao Cao can be regarded as my opponent, and it is not a shame to lose to Cao Cao. What kind of dog is Lu Bu! This kind of dog also deserves to take advantage of me? I swear to kill this thief! I'd rather Runan be empty than kill Lu Bu with all my might! As for the emptiness of Gyeonggi, then send the troops of Lujiang to the north to change the defense! ”

Yan Xiang Yang Hong's persuasion was ineffective, and the generals below could only carry out the holy decree, and Li Feng of Kuxian County was forgotten, and no one tried to save it, so it was given to Cao Cao for nothing.

In the end, Yuan Shu did not forget to add an explanation, and asked Da Honglu (the imperial court in charge of diplomatic work) to immediately go to the post house to take down Lu Bu's envoy Qin Yilu, and send him to Shouchun downtown to behead the public, so as to reciprocate the revenge of Lu Bu sending the envoy to behead.

This insignificant change also brought a little butterfly effect - because Qin Yilu died two years earlier than the same period in history, he was not able to create a son Qin Lang with his wife Du Shi. Qin Lang completely disappeared from history.

……

But not to mention, the emaciated camel is bigger than the horse, although Yuan Shu has been defeated several times in a row, but after all, it occupies a large area of plastered land, Yuzhou was originally densely populated, and the mobilization of all the rivers and fisheries can still quickly pull up a wave of troops.

Lu Bu just came to sneak attack this time to take a small advantage, just to see that Cao Cao was carrying the main force of the Yuan army, and he took advantage of the void to get a vote.

In addition, Lu Bu himself is capricious, so he is also more suspicious about whether others will be capricious. Even if he has taken refuge in the imperial court, he still has to station heavy troops in Suiyang, the core of Liang County, and he is afraid that after his main force all goes south, Cao Cao will turn his face and attack him.

The combination of various factors, Lu Bu did not use many troops to steal Yuan Shu this time, and there were only more than 20,000 people.

Unexpectedly, he only captured a few counties, but he actually encountered Yuan Shu's reaction so fiercely, ignoring Cao Cao and Liu Bei, and went north to fight for his life with the army of the country.

The two sides broke out a field battle around Qiaoxian, because the number of Lu Bu's army was less than 30% of Yuan's army, and most of them were local soldiers in Xuzhou, the quality advantage of the soldiers was not obvious.

And because Yuan Jun held his breath, the revenge mobilization before the war was relatively good, and the treacherous propaganda against Lu Bu was relatively in place, and the morale was rarely raised. After a hard battle, he actually defeated Lu Bu, and Lu Bu's 20,000 Xuzhou troops lost more than half, so he could only return to Suiyang with his henchmen and veterans.

Yuan Shujun's casualties were actually more than Lu Bu's, and there were many soldiers who escaped in this decisive battle, but after all, they swarmed up and won.

This can be regarded as setting up a prestige for Yuan Shu, telling the world: He was only so embarrassed by the princes, if he didn't care about focusing on fighting with one of them, no one of the princes would be sure to beat him Yuan Shu!

And Cao Cao took advantage of Yuan Shu's all-out revenge on Lu Bu, and had already taken Kuxian, and Li Feng finally collapsed and surrendered. After clearing the entire territory of Chen County, Cao Cao took advantage of Yuan Shu's lack of calmness and went south to infiltrate Runan.

Cao's army set out from Yingchuan County, where Xudu was located, and went down the Rushui River to break through Dingying, besiege Shangcai, and fought with great success—but this was all after the first month of the third year of Jian'an.
