Instigated Xiang Liang to send a partial division to attack the surrounding cities and lands that were still controlled by the Qin army, Xiang Kang's move was actually for his own sake, and he planned to take this opportunity to continue to work alone and once again strengthen his seriously weakened lineage, but Xiang Kang soon found that his wishful thinking was too good, first of all, there were more than one or two generals of the Chu army who had plans with Xiang Kang, and some people robbed Xiang Kang's deal, and secondly, Xiang Kang seriously underestimated the political mind of the hero's second uncle Xiang Liang.

Of course, if it was to follow other bosses, Xiang Kang would definitely not dare to dream that he would be able to get the opportunity to sweep away rookie opponents and continue to grow his strength - Xiang Kang's direct army was originally the most in the Chu army, no matter which boss would not guard against Xiang Kang at all, and it would never be possible to give such a good opportunity to Xiang Kang again. But for Xiang Liang, Xiang Kang has a lot of illusions, and always feels that the second uncle of the hero loves himself from the bottom of his heart, and he also has a deep sense of guilt for himself, and he should give himself a little compensation, so Xiang Kang chose to open his mouth to agree to send troops, and tried his best to get the opportunity to continue to lead the army alone.

Xiang Kang's own heroic second uncle, relative to Xiang Bo, Xiang Liang loves Xiang Kang very much, but Xiang Liang also loves other Xiang family children, and although Xiang Liang has no fear of his nephew, but since Xiang Kang's army is already the most among the generals of the Chu army, in order to balance the strength of the generals in the army, there is such a good opportunity, Xiang Liang is of course more willing to hand it over to other Xiang family children. So only one day had passed, and Xiang Liang made up his mind and decided to let Xiang Yu, Xiang Sheng, and Liu Laosan each lead their own men and horses to form a partial division of the Chu army, and go north to sweep the semi-blank area that was still controlled by the local army of the Qin army.

After Xiang Liang announced this decision, Xiang Yu, Xiang Sheng and Liu Laosan were of course overjoyed, and hurriedly thanked Xiang Liang together, but Xiang Kang and the other Chu generals were disappointed, and Xiang Kang, who had worked hard in vain, was even more depressed, and it was rare to cry in public. Xiang Liang saw Xiang Kang's thoughts, so he said: "Kang'er, don't blame your uncle for not giving you this opportunity, your uncle left you in Pengcheng for your own good, you have to understand your uncle's hard work for you." ”

"From today onwards, you will come to your uncle every evening, and your uncle will teach you how to fight." Xiang Liang continued: "You are indeed talented in military tactics, in many places even my uncle and I may not be able to match you, but your battle is too poor, you must be strengthened, take advantage of the time and opportunity now, uncle, I will personally help you make up for it, lest you continue to be afraid of fighting in formations, and the enemy will seize your weakness." ”

"Brother, why don't you thank your uncle?" Xiang Yu patted Xiang Kang on the shoulder and said with a smile: "Not everyone has such good luck to have your uncle teach you to learn battle by yourself." ”

It was hopeless to continue to work alone, and at the same time, his shortcomings in the battle really needed to be strengthened, Xiang Kang had no choice but to respectfully thank Xiang Liang for his kindness. At the same time, out of duty, Xiang Kang said to Xiang Liang again: "Uncle, about Brother and Pei Gong's northern expedition, the little nephew has a few words to say, the little nephew thinks that Brother and their northern expedition should give priority to attacking the cities along the Chi Road, relying on the Chi Road, and then attack the surrounding cities. In this way, our army can not only maintain smooth communication with the partial division, but also can quickly retreat when encountering a strong enemy, and it is not easy to become a lone army. ”

"That's a good idea." Xiang Liang nodded, and then ordered: "Yu'er, Sheng'er, Peigong, keep this suggestion of Kang'er in mind, and after going north, remember not to stay too far away from the Chidao, lest the tyrannical Qin army cut off your connection with the rear and fall into danger." ”

Xiang Yu, Xiang Sheng and Liu Laosan agreed together, but after agreeing, Xiang Yu said with a big grin in his heart: "In one more move, the tyrannical Qin army in the north is a rabble, and the main force of Zhang Handpifu is far away in Chenliu, even if we stay away from Chidao, what danger can we have?" ”

In this way, under Xiang Liang's arrangement, Xiang Yu, Liu Laosan and others soon took the partial division north to attack the city and plunder the land, while Xiang Kang was forced to continue to stay in Pengcheng, and had to go to Xiang Liang's army every day to receive Xiang Liang's personal teaching, and learn the art of war from scratch. But fortunately, Xiang Liang supervised Xiang Kang strictly, but he taught him very carefully, no matter how stupid Xiang Kang was in this regard, he never scolded at will, and patiently just taught Xiang Kang all the battle methods left by the ancestors of the old Xiang family, and indeed let Xiang Kang, who was weaker than the battle, learn a lot.

In addition, Xiang Kang also has the advantage of staying in Pengcheng that he can often go back to the city to visit his beautiful wife and beautiful sister-in-law, although Yu Miaoge is pregnant and it is inconvenient for Xiang Kang to continue to mess around, but the sweetness and gentleness of the beautiful sister-in-law still make Xiang Kang happy, so even if he is a little disappointed, Xiang Kang is not too depressed, and his life is quite free.

At the same time, the good news of the northern front also flew back to Pengcheng like snowflakes, and after the Chu army led by Xiang Yu and Liu Laosan went north, they first quickly captured Zou County, an important throat of Qin Chidao, and then easily took Pingyang, and then defeated the main force of Xue County's county soldiers in Lu County, the county of Xue County, and took Lu County by chance. Xiang Liang was overjoyed when he received these news, but Xiang Bo, who was resolutely opposed to the expedition, kept muttering behind his back, "Zhang Handpifu is not far away, why are you so fierce?" is not afraid of being recruited by Zhang Handpifu's main force. ”

Xiang Bo was really right this time, in fact, Zhang Han's army in the area has actually been closely monitoring the Chu army's every move, and just received the news that the Chu army was going north, Zhang Han also immediately moved to Yangwu with the main army that had been resting for a while, ready to march east along the Chi Road and enter the Dangjun battlefield at any time.

However, Zhang Han did not rush to send troops, even if he received the news that Zhilu County of Dangjun County was broken by the Chu army's partial division, Zhang Han still did not move, but closely maintained contact with the Ludi Qin army, and patiently waited for the next move of the Chu army's partial division. In this regard, all the generals of the Qin army were very puzzled, and asked Zhang Han one after another: "General, Lu is empty, if we don't hurry up and send troops, I'm afraid that the cities around Lu County will be in danger, why don't we hurry up and send troops to rescue?" ”

"Don't rush, wait a little longer." Zhang Han sneered and said: "Xiang Liang's rebel thief's partial division is still moving along the gallop road, we are now sending troops, they find that the situation is not right, they can immediately take the gallop road and quickly escape, let us run in vain, we have to wait for them to stay away from the gallop road, and then we suddenly march into the army, so that we can hope to catch them in the urn." ”

When Zhang Han made this decision, the Chu army's partial division, which was getting happier and happier, had already entered Jibei County along a galloping road dozens of meters wide, and directly launched an attack on Boyang City, the county of Jibei County, but unfortunately, the Chu army's partial division finally encountered a hard stubble this time, and the Jibei Qin army, which learned the lessons of the friendly army of Xue County, concentrated its forces and defended Boyang, and at the same time, the city of Boyang was also very strong, and the Chu army's partial division failed to succeed in many strong attacks, on the contrary, it also paid a lot of casualties.

Unable to take Boyang alive or dead, Xiang Yu, who was in a hurry to make contributions, changed his mind and found Liu Laosan to discuss with Xiang Sheng, planning to abandon Boyang and move east to attack Wuyan and Zhangxian and other places. However, Xiang Sheng was quite worried, and said: "Brother, Wuyan is too far away from Chidao, and my uncle told us not to stay too far away from Chidao, is it against my uncle's military order to do so?" ”

"Afraid of what?" Xiang Yu asked angrily and said, "Uncle told us not to stay away from Chidao, because he was afraid that we would be in danger, but the area around Wuyan is full of violent Qin County soldiers, who can be our opponent?" Zhang Handpuff's main force has not moved, what else do we have to fear? It was so decided, and immediately led the army westward to fight Wuyan and Zhangxian. ”

Unable to resist his lobby brother, Xiang Sheng could only obediently follow Xiang Yu and Liu Laosan's army to leave the gallop road, and come west to fight the densely populated Wuyan and other places. As a result, after the news was sent to Zhang Han by the Qin army, Zhang Han didn't even blink his eyelids, and immediately shouted: "Order the whole army, immediately pull out the camp and raise the army, march east along the galloping road, and rush to Puyang at full speed!" ”

It was convenient to march on the ancient highway with a width of dozens of meters, and it only took three days for Zhang Han's main force to drive to Puyang City. At the same time, after successfully taking the two county towns of Wuyan and Zhangxian, the greedy Chu army continued to go north and went to attack Xuchang again.

Confirming the movement of the Chu army's partial division, Zhang Han was even more overjoyed, and hurriedly recruited his subordinate general Sima Duan and instructed him: "General Sima, I have 20,000 troops with you and 4,000 elites in Longxi, you must rush to Zou County within five days, take the city to cut off the retreat of the rebel division, and create an opportunity for our army's main force to annihilate the Chu thief division!" ”

"General, it won't take more than five days." Sima Duan said very confidently: "There is a way to go from Puyang to Zou County, four days!" Within four days, the last general must have rushed to the city of Zou County with his army. ”

"That's the best." Zhang Han nodded with satisfaction, and then instructed: "Remember, after taking Zou County, immediately divide the troops to go north to fight Lu County, even if you can't succeed, you must block the way back to the city for me to block the Chu thief's partial division, so that they can't enter Lu County!" Don't worry about being alone, my main force will arrive soon. ”

Sima Duan agreed loudly, hurriedly sorted out the soldiers and horses, and on the same day, he took the Qin army's partial division to the east along the Chi Road, and went to attack the throat of Zou County day and night. Zhang Han calmly packed up the army, let the main force of the Qin army rest for a while, and prepared to go east to clean up the Chu army's partial divisions, and at the same time organize manpower to open up the Yellow River and transport grain from Aocang to Puyang to hoard in order to supply the front line for combat.

Zhang Han's movements are too fast, and the speed of information transmission in this era is too cheating, or after Zhang Han took the main force of the Qin army eastward and crossed Zhen City, the Chu army's partial division that had already entered the territory of Dongjun was shocked to find that the main force of the Qin army was not far from his own army, and then even Xiang Yu, who was brave and good at fighting, did not dare to have any hesitation, and immediately led the army to retreat to Chidao, Zhang Han led the army to chase after him, while calmly recovering the city that had fallen before, while smiling and striding to chase and kill the Chu army's partial division that was too lonely and deep.

Or when the embarrassed fled back to the gallop road, the Chu army's partial division received the news from the rear, knowing that the Qin army's partial division Sima had rushed to Zou County successfully, not only cut off the retreat of the Chu army's partial division, but also cut off the Chu army's partial division and the rear of Pengcheng and the Chu army in the East China Sea, Xiang Yu and Liu Laosan and others complained repeatedly, but they did not dare to delay, they could only try to throw down the grain and grass that they had finally grabbed before, and retreated to Lu County in embarrassment, and was caught up and defeated by the Qin army several times on the road, and the loss was quite small. Almost all the results of this northern expedition were lost.

When they finally fled to the vicinity of Lu County, they received news that the Qin army's partial division Sima had divided his troops to the north, and took the first step to take the city of Lu County, which was strong and hoarded a large amount of grain and grass, Xiang Yu and Liu Laosan and others had no choice but to quickly divert to the west and hurriedly retreat to the small city of Bianqiu, and the main force of the Qin army continued to chase closely, forcibly forcing the Chu army's partial division into Bianqiu to temporarily avoid the edge, and then quickly surrounded Bianqiu. Xiang Yu and Liu Laosan, who were cut off from the back road, did not dare to risk breaking through, so they could only quickly send people south to ask Xiang Liang for help.

It was still affected by road traffic, or when the Chu army fled to Lu County in embarrassment, Pengcheng received the news that the Qin army's partial division was successful in attacking Zou County, and it was confirmed that the main force of the Qin army was advancing eastward. Xiang Liang was shocked when he heard the report, so he could only quickly convene the generals of the Chu army to discuss countermeasures and discuss the plan to go north to rescue the deviant division.

Finally it was the turn of Xiang Bo Xiang Master to be majestic, in front of everyone in the Chu army, Xiang Bo foamed at the mouth, scolded Xiang Kang, who proposed to send a partial division to the north, and desperately accused Xiang Kang of cheating his father, causing the Chu army to fall into danger. Xiang Kang was very aggrieved and retorted: "Can you blame me for this? When Brother and they left, I repeatedly reminded him, telling them not to stay away from Chidao, but they didn't listen, otherwise, how could the tyrannical Qin army rush to Zou County and succeed? ”

"Dare to quibble!" Xiang Bo jumped three feet high and roared angrily: "If it weren't for your bad idea to let our partial division go north to provoke the violent Qin army, how could Yu'er and them go so far alone?" I'm telling you, Yu'er, they're fine, if something happens to them, I will never spare you! ”

"That's it!" Xiang Liang finally spoke, and scolded: "Uncle Xiang, don't mess around just because you are an elder, it is my decision to let the partial teacher go north, and it has nothing to do with Kang'er!" Don't say these useless words again, the most important thing now is how to bring Yu'er and them back, this is the big thing. ”

Xiang Bo had no choice but to shut up, but Old Man Fan stood up and said to Xiang Liang: "Wu Xinjun, since Zhang Handpifu has personally led the main force eastward, if our army wants to rescue the isolated partial division, the only way can only be to exhaust the main force and go north to save General Xiang Yu and them." Xia Guan proposed that Wu Xinjun should personally lead the troops to the expedition this time. ”

"That's the only way." Xiang Liang nodded helplessly, and after a little calculation, he ordered the main force of the Chu army to prepare for the expedition immediately, and decided to leave Cao Zhi to guard Pengcheng and personally lead the army to rescue the deviant division. During this period, Xiang Kang proposed that the Chu army only bring ten days of grain and grass to the north, so that the Chu army in the East China Sea could take on the logistics responsibility, but Xiang Liang did not accept it, insisting that the army carry a month's grain and grass to go on the expedition, Xiang Kang had no choice but to give up his proposition.

Xiang Liang was too cautious in terms of grain and grass, giving the Qin army quite enough time to prepare for the war, taking advantage of the opportunity for the main force of the Chu army to carry heavy grain and grass to the north to rescue, Zhang Han quickly adjusted the garrison, let Sima Duan gather troops to defend the city in Zou County, firmly choke the throat of the Chu army going north, and explained that Sima Duan could not fight when the main force of the Chu army arrived in Zou County, and was only allowed to hold the city. At the same time, he commanded the main force of the Qin army to dig trenches, completely trapped the Chu army's partial division in the city of Bianqiu, and transferred grain and grass from all over the city to hoard in the city of Luxian in order to confront the Chu army for a long time.

It was still when the preparation of the Qin army was almost done, and the main force of the Chu army on the way north received accurate news, knowing that Xiang Yu and others were trapped in the flawed hill, and as a result, Xiang Kang, who was the first time as a general, also saw Zhang Han's purpose at a glance, and said with certainty: "A typical siege of the city to send reinforcements, Zhang Handan deliberately surrounded the flawed hill without fighting, and at the same time divided his troops to hold Zou County, clearly trying to lure us to attack Zou County, with the help of a strong city defense to consume the strength of our army, and when we were exhausted by the old man, he made another effort to attack the flawed hill, Take the flawed hill and then come to our main battle for a decisive battle. ”

"It is also possible not to attack the flawed hill, and directly attack Zou County, and cooperate with their Zou County defenders to flank our main force before and after." Uncle Zhou, who was accompanying him, put forward another possibility, saying: "This is also Zhang Handpifu's usual method, which makes us have the illusion that as long as the Defective Hill is still there, his main force will not leave the Defective Hill, and then suddenly make a move, he can kill us by surprise." ”

"Is there any way to deal with it?" Xiang Kang asked.

Uncle Zhou didn't answer, and after thinking carefully for a long time, Uncle Zhou said: "Let's wait until we get to Zou County, if my prediction is not bad, Zhang Handipf is deployed according to my estimate, we may have the opportunity to smash Zhang Handipfu's dream of besieging the city and sending reinforcements, and in turn force him into a Jedi." ”

This time to the north to rescue the trapped partial division, not only Xiang Kang led the army as a general, and there was no way to continue to command the whole army like an arm, but also the first expedition after the reorganization of the Chu army, with a total strength of more than 70,000 people, the momentum was very huge, and at the same time, the elite was exhausted, except for Xiang Yu's department who was trapped in the flawed hill, almost all the troops that the Chu army could fight were taken north by Xiang Liang to the territory of Xue County. So although he was anxious, Xiang Liang was still full of confidence, believing that the army would be able to successfully take the throat of Zou County and arrive at the foot of the city to rescue the trapped partial.

It was only after arriving at the city of Zou County with the main army that Xiang Liang found that he was still a little underestimated by the enemy, and he regretted that he did not take Xiang Kang's suggestion and went north with the army lightly, giving the Qin army too much time to prepare for war. Because taking advantage of the opportunity of the main force of the Chu army to carry heavy grain and grass to the north, the Qin army has established extremely strong fortifications under the city of Zou County, not only rushed to build a high and thick camp wall early, built countless fortifications, but also dug three wide and deep trenches to protect the camp, like a hedgehog wrapped in a ball, smiling and waiting for the Chu army to open its mouth to gnaw.

"Zou County is not easy to fight, even if we can barely beat it, we will definitely lose a lot, and we don't know how much time it will take." This is the unanimous conclusion reached by Xiang Liang and Xiang Kang.
