Of course, due to the natural conditions in Gangneung, all infantry cavalry were required to participate in a ten-day sailor training every three months, including sailing and surface shooting, slashing, etc., while Ganning's sailors were also required to arrange at least three-thirds of the time to train on the road, including cross-country and jungle cross-country and rapid marches, etc.

The boundaries between the various arms were blurred, and archers had to master spear stabbing and sword and shield formations, while sword and shield men and pikemen were actively engaged in shooting training. The generals who were accustomed to Liu Cong's toss no longer spoke out to stop them. After all, so far, Liu Cong has led everyone to achieve good results.

What put pressure on Liu Cong was Huang Quan's intelligence, most of which was about Cao Cao. Today, Huang Quan's Jinyi Guards have a scale of nearly 500 people, scattered all over the country, of course, the focus is on Cao Cao and Sun Quan.

Intelligence shows that since the tenth year of Jian'an (205), Cao Cao followed the advice of the strategist Guo Jia and used the famous scholars of Qing, Hebei, You, and the four states as his subordinates, in order to win over the scholars. Yuan Shao's strategist Chen Lin was a famous soldier for a while, and before the battle of Guandu, he drafted a letter for Yuan Shao, with fierce rhetoric, counting Cao Cao's crimes, insulting and his family history. In order to recruit talents, Cao Cao took Chen Lin under his door, and made him and the famous Ruan Yu in charge of the bookkeeping office and specialized in clerical work. As a result, the hearts of the people of the four states were attached to Cao Cao. Speaking of which, this Cao Cao is really an adult, and there are a lot of them.

In August of the same year, Zhao Qian, Huo Nu and others, who were from Zhuo County, Youzhou (now Zhuo County, Hebei), gathered people to rise up and kill Youzhou Assassin Shi and Zhuo County Taishou. Cao Cao personally led the army into the attack and beheaded Zhao Qian, Huo Nu and others.

Subsequently, the three counties of Liaoxi, Liaodong, and Youbeiping attacked Liping (now eastern Hebei), and besieged the Liao general Xian Yufu on the left. In August, after Cao Cao defeated Zhao Qian and others, he crossed the Lu River (the North Canal below Tongxian County, Beijing) to rescue Qianping, and Wuhuan fled out of the Sai.

In the first month of the eleventh year of Jian'an, Cao Cao personally led the army to attack Gaogan and besieged Huguan (now Taihang Pass in the northeast of Licheng, Shanxi). The senior cadres will defend the city and ask the Huns for help. Gao Gan prepared to flee to Jingzhou (present-day Xiangfan, Hubei), where he was captured and killed by Cao Cao's Shangluo Commander Wang Yan. At this point, the high-level cadres were destroyed, and Cao Cao pacified and annexed the state. Liu Cong suddenly felt a little remorseful, this senior cadre may be a little useful, his historical knowledge is still not too strong, he knew that he would send someone to take over the senior cadre, leaving a bane for Cao Cao.

If the estimate is correct, then Cao Cao selected Liang Xi to govern and annex the state, and in order to conquer the three counties of Wuhuan, he dug the two canals of Pinglu and Quanzhou to pass through water transportation. After the opening of the second canal, the materials south of the Yellow River can pass through Baigou, enter the sea with this second canal, and then go directly to Liaodong by sea. At this point, Cao Cao made material preparations for the northern expedition to Wuhuan.

After breaking Wuhuan, Cao Cao no longer has any worries.

It is getting closer and closer to Cao Cao's pacification of the north, and the day when Cao Cao pacifies the north is when he marches south, the dark clouds in Liu Cong's heart are getting bigger and bigger! And Sun Quan didn't let Liu Cong worry about it. From his own crossing to the Battle of Chibi, Sun Quan and Huang Zu have waged many tug-of-wars in Jiangxia, and they have injured each other.

Speaking of Jiangxia, we have to say Huang Zu, Huang Zu can be said to be very important to Jingzhou now, and it is also true in history. Although the name of Huang Zu was not familiar to later generations, in view of the geographical location of Jiangxia, and Huang Zu was ordered to guard Jiangxia and compete with the Jiangdong Sun clan several times, Liu Cong also had an understanding of the military field. Huang Zu's commanding ability should be similar to him even if he can't compare to Cai Mao, otherwise Liu Biao would not be at ease to let Huang Zu guard Jiangxia for more than ten years.

As early as the period of the group of heroes, Jiangdong Tiger Sun Jian died in Jiangxia. The 10,000-strong Jiangdong Army was almost wiped out in less than a day under the counterattack commanded by Jiangxia Taishou Huang Zu, and Sun Jian's defeat was due to many reasons, one was that Luoyang went south non-stop. It belongs to the labor division far away, the second is to go deep into the hinterland of the enemy, Liu Biao's Cai Mao Corps outflanked from the flank, Huang Zu guarded the Yangtze River ferry with heavy troops so that it could not enter, in addition, Liu Pan and Huang Zhong's troops had already been deployed in the south of the Yangtze River, and Sun Jian was an immortal at this time, so he didn't want to fly over from Jiangxia.

Facing Liu Biao's strong soldiers. Sun Jian chose to attack from the front, of course, his courage was commendable, and he deserved to be the Jiangdong Tigers, but the 10,000-strong troops were fleeting in an instant, leaving Sun Ce to surrender to Yuan Shu in the south. A few years later, Sun Quan and Huang Zu engaged in a tug-of-war over control of Jiangxia. Among them, in the eighth year of Jian'an, Sun Quan went west to Huangzu and broke the ancestral boat army, but the city was not conquered and the rear Shanyue was ready to move, so Sun Quan had to return to the camp.

In the eleventh year of Jian'an, Jiangxia Taishou Huang Zu sent the general Deng Long to lead thousands of troops into Chaisang, but was attacked by the Wu general Zhou Yu, and Deng Long was captured.

In the twelfth year of Jian'an, Sun Quan went west to conquer Huangzu and captured tens of thousands of people. was also defeated by the same general in the same place where Sun Jian died that year, and also lost a general, his name was Ling Cao.

Of course, the later adjustment of Liu Biao's army deployment will be heavy to the north to prevent Cao Cao from causing the emptiness of the troops on the southern front. With the assistance of Gan Ning and others, Sun Quan finally succeeded in the sneak attack on Jiangxia, but unfortunately a generation of famous generals Huang Zu ended like this. Although Huang Zu's personality is not very good, he is clean and beautiful in these two tactical commands.

But it was precisely because of Huang Zu's death that Sun Quan successfully occupied Jiangxia, which also led to Cao Cao's impatient southern expedition. Cao Cao didn't want to see Jingzhou fall into the hands of Sun Quan, which directly led to the Battle of Chibi and opened the prelude to the Three Kingdoms.

From Liu Cong's point of view, with public and private, Huang Zu can't die, and Jiang Xia can't lose it! Jiang Xia's rescue in hand can delay the time of Cao Cao's southern expedition, and Huang Zu can increase the number of generals who lead the army if he does not die.

Regarding the strategic position of Jiangxia, I believe that Liu Biao, Cao Cao, Liu Bei and Sun Quan have their own thoughts, but there is one thing in common, that is, it is really important and a strategic location. Liu Cong, who has studied the history of the Three Kingdoms, naturally understands how important Jiangxia is to Jingzhou and to his ongoing career!

Liu Cong has a map of the Three Kingdoms in his heart, open this map, and soon find Jiangxia near the center of the map, on the north bank of the Yangtze River in the middle reaches of the Yangtze River. It is surrounded by mountains and a large area of the Yangtze River flood area, because the terrain is high, the Yangtze River flood cannot submerge Jiangxia, so Jiangxia has become a settlement in this area and the population is relatively dense. In the era of cold weapons, population means economy, means financial and combat power!

But this does not mean the importance of Jiangxia's strategic location. Jiangxia in the Three Kingdoms era belongs to the three kingdoms of the junction of the important land, to the northeast can go straight out of Shouchun to attack Hefei, to advance to the northwest but can go out of Xiangyang to take Fancheng, if Hefei, Jiangxia, Xiangfan. The three places are seen as a whole. Then it just becomes a strategic system of character type.

In Cao Cao's later years, he defeated Guan Yu and Sun Quan with this defense system of great depth strategy, and Zhang Liao, who was admired by many people in later generations, also became famous in a war because of this defense system, and General Cao Ren also achieved the honor of a general with this strategic system, but the real hero is also a famous general who is often overlooked. That is Jiangxia Taishou, the general Wenpin. Fortunately, now this general is in his own hands!

Cao Cao's southern expedition, Liu Bei abandoned Xinye, ran to Xiakou, threw himself into Jiangxia, looked at Liu Huang's uncle's action route, the starting point was Xinye, and then passed through Xiangyang, and then changed the route to Xiakou, which gave everyone room for imagination, why did Liu Bei not choose Xiangyang as the destination, but chose Jiangxia? In fact, the reason is very simple, if Liu Bei captures Xiangyang at this time, then he will independently withstand Cao Cao's attack, and there is no backup guarantee in the Xiangyang area, but Cao Cao's troops will quickly form a siege of Xiangyang, at this time, they can't run away if they want to, and it is only a matter of time before the whole army is annihilated.

Liu Bei chose Jiangxia, but with this, Liu Cong admired it very much, and the facts also proved Liu Bei's wise choice. Of course, it is good in Jiangxia, but military isolation can also make the initiative passive, so Liu Bei couldn't wait to sign an alliance with Sun Quan, in fact, Sun Quan was also afraid, what are you Liu Bei doing in Jiangxia, a pair of old cat eyes stared at my one-third of an acre, leading Cao Cao to my front, making me sleep with nightmares, the motive is shameful!

In this way, Sun Quan sent a Lu Su and said let's form an alliance. In this way, Liu Bei's support was guaranteed, and of course, the security of Sun Quan's flanks was completely handed over to Liu Bei, which was also the most important law code for Liu Bei to play scoundrels in Jingzhou later, Jiangxia was the thorn in Sun Quan's eyes, and he couldn't occupy it, because he occupied it, and he would face Cao Cao with most of the Yangtze River defense line.
