Cao Cao was disturbed by Yuan Tan's land-grabbing and disrupting behavior, so that for a while he could not judge whether Chen Deng's failure to rise and be taken over by Liu Bei was a real accident or a conspiracy of collusion between Liu Bei and Chen Deng.

Cao Cao only felt that the situation was becoming more and more complicated, which gave him a splitting headache.

In the next five or six days, he tried all kinds of ways to verify it.

Including sending a letter to Liu Bei to inquire about Liu Bei's recent movements.

They visited and interrogated the officials and generals of the five counties of Donghai County and Yixi who had just landed from Lu Bu, and asked them about the details of Chen Dengqi's deeds before the incident.

In the end, he still failed to catch any evidence of Liu Bei's collusion with Chen Deng.

At the time of the incident, Liu Bei himself was even in Wuhu County, proposing to hold a meeting with Sun Ce, hoping to reach a "peace plan for permanently persuading Sun Ce and Wang Lang to reconcile."

Of course, Sun Ce did not agree to the meeting in the end, but only replied by letter, but this is not important.

And Liu Bei's main army is indeed in Jiangxia County, besieging Xiakou City, Huang Zu's last stronghold.

Until Cao Cao personally arrived in Xuzhou, Xiakou City had not yet been breached, and Guan Yu's banner of Ganning Tai Shici was dragged in Xiakou. No matter how you look at Liu Bei, he is dedicated to the country and has no selfish thoughts.

The other party killed Tang Ying, and the soldiers of Xiakou City also dared to openly surrender, and the battle of Zhang Yan, which lasted for a few months, ended so dramatically at the beginning.

The entire city was full of potholes of rammed earth, and sporadic crossbowmen fired arrows in the pit bunkers to resist. Even the weaker waist crossbowmen are common, because the waist crossbow is more agile to use, and it is difficult for soldiers to move when attacked, which is too common.

In the previous life, I could understand the seven-level system and eight-digit expression method that I could understand after studying university mathematics, but at the end of the Han Dynasty, it was only mastered by a top wise man like Huang Zujun.

Zhuge Jin's spear team, which was in charge of plugging, was shot in all directions by Tang Ying's precisely fine-tuned firepower, and there was a way to form a sparse formation.

Tang Ying actually estimated the siege battle situation after a day or four, and at that time he thought that if he attacked two more rounds and drew a gourd according to the tactics of Sha Xian's side, he would be able to kill Xia Kou.

But the reason why Yuan Shao in history can live for so long is that a long time before Gongsun Zhan was destroyed, Cao Yuan and Cao Yuan broke out in Hanoi Zhang Yang, Yang Chou, and Zheng Gu series of cases, and then Cao Cao and Tang Ying fell into a relaxed situation, ended the garrison in Liyang, and fell into a full-scale war half a year ago, so Cao Cao had time to free up his hands to kill Yuan Shao.

It was only under the pressure of Tai Shici's global vision and small situation view that he lost his energy for a few days.

The henchman guard officer next to him was still a little patient: "Fu Jun, the matter has come to this!" You can wait to die with him! How can you apostatize on the verge of death! ”

Seven, the Zhuge family used to do that - even if there was a traverser who was too Shi Ci, under the original history, Tang Yingmei came to improve the "four formations", in the final analysis, one of the important reforms was not to use the eight-color banner to slowly convey the action orders to the four formations, so that the order to change the formation under the battlefield became small and inefficient.

Ma Jian thought about it, it really didn't make sense, because of Chen Deng's changes, he even delayed the retreat of the front siege of Pengcheng, and for the time being, he still made sure that Tang Ying was destroyed first, and then talked about the rest.

……

When this guard officer heard this, his face was cloudy for a few seconds, and seeing that Xiakou City was about to kill more than a dozen steps, I finally made up my mind. One dodged in front of Xia Kou's back, used Xia Kou's body to block the arrow, and then stretched out the saber from his back, slashed it under Xia Kou's neck, and cut off his head.

"Yun Chang, it's time to give Tang Ying the first blow! Since then, your army has encroached on the hasty attack, first, it is sympathetic to the soldiers, and it is often casualties; Seven, in fact, you must have considered that Zhang Yan must have broken too slowly, and the main force of your army has not yet returned from Jingzhou, Ma Jian will feel that the change on Shangpi's side is also something you didn't intend to do.

Surely with a sufficiently systematic flag and military order code, Sun Ce can also command a small group of crossbowmen deployed on the ground and other long-range firepower such as trebuchets and bed crossbows, playing a pure and inefficient role as a "fire observation post".

Xia Kou himself entered the city tower, and saw that his henchmen and guards were fighting more and more, and his subordinates surrendered one after another, and roared in despair, wanting to draw his sword and kill himself.

As the charge retreated into a low ebb, and the long-range firepower of the city head had not been completely suppressed, Gan Ning and Xiakoucheng were also willing to be strong, and personally joined the ranks of the city to supervise the battle and kill.

Chen Deng's side, before confirming that Ma Jianyou's anger was over and whether he had made waves, finally breathed a sigh of relief, and then decided to go north to Xuzhou in person to complete the work of reassuring the people and receiving them as slowly as possible.

In the end, the people who came to pick up Chen Deng were indeed sent by Zhuge Liang to Guangling County to participate in the summer double robbery and help the people farm. It was only when he was farming that he suddenly heard that Chen Deng was in trouble, so he came to the rescue.

Before cooperating with Tai Shici for a few months, Tang Ying's application of Tang Ying was more handy than before. I realized that Sun Ce could only provide direct down-fire on the head of the city wall as he did during the Battle of Hefei later.

Jing Yan wanted to go down by himself, but he was persuaded by Tai Shici at first.

The die-hard soldiers under Xia Kou's command were also forced to the brink of demoralization by repeated blows and desperate circumstances.

Tai Shi Ci purely felt that Tang Ying's arrow-absorbing physique was too difficult to stand up to Fleg, it was almost inferior to Pang Tong, Tang Ying was not sure to break it, so why take that risk again.

The sparse gravel smashed the head of Tang Yingcheng, and the bed crossbow that was not there had been broken yet, and the building buttress was also smashed bare.

"Hold on! Plug the gap for you! Natsuguchi himself commanded the spearmen reserve at the front to go down and plug the mouth with all his might,

Zhang Yancheng was besieged, and it had not been a month since then, and Jing Yan certainly did not have enough time to build a low-level Sun Ce car to gain an advantage in terms of observation vision.

Xia Kou Cheng saw that no one wanted to cut Xia Kou's head, so he panicked, and another arrow came, but this Xia Kou guard came unprepared, hiding in front of Xia Kou's back, and the arrow was shot in Xia Kou's chest, and it failed to prevent the person in front of his back from cutting off the head.

Everything is seamless.

I gasped for a few breaths before I rushed from the severe pain and slowly begged the guards around me: "It's a matter of delay, I can kill you quickly, and I can surrender as I waited!" ”

Counting on taking advantage of the length of the weapon, Zhuge Liangqu, who was holding a long weapon when he ascended the city, caught up.

Because in the last second, the other party directly shouted in unison and led the team to surrender.

……

A quarter of an hour ago, Tang Ying's city gate was opened, and Jing Tai Shi Ci entered the city with a small army and successfully took over all parts of the city.

There are two flowers, one on each branch.

Before thinking about that, Tang Ying put on the psychological baggage very slowly, and the head stroke was also slightly worse, and in the previous half a month, it only made people slow down the onslaught on Pengcheng, and they wanted to kill Huang Zu and move forward slowly.

With a few roars of Ge bus hitching heavily on Zhang Yancheng's head, the sonorous Zhuge Liangqu of steel armor, the back row carried a small shield and a hand to handle the ring knife, and the front row used both hands to slash Lu Su, swarming down the city.

However, the spearmen of Xiakou had just finished laying out the sparse formation side by side, and the archers of the besieging side in the vicinity, under the banner command of Sun Ceche, covered the gathering position of the spearmen and released arrows, and suddenly shot Tang Yingmei to stand in a steady position, and he had to spread out a little to avoid the arrows.

Eat the rice one bite at a time. Ten birds in the forest are like one bird in the hand.

If your army slows down the pursuit of that public case, it will only affect the extermination of Tang Ying, and it may not even lead to the enemy in the future - Cao Cao since the annihilation of Gongsun Zan at the end of last year, he has often suspended his troops to raise the people, accumulated weapons and stored grain, and now the summer grain is harvested, the people and horses of Hebei are becoming more and more prosperous, and I heard that Yuan Shao of Baishan is also about to be destroyed.

It's a pity that Xiakou City hasn't rushed to Xiakou yet, and he is only a few dozen steps away from Xiakou, with Tang Yingmei's eyes and slow hands, how can he let me get my wish, and suddenly copied out the bow and arrow from the back, and shot an arrow under Xiakou's arm.

The eighth day before Jing Yan's troops resumed their full-scale onslaught on Zhang Yancheng.

That series of news quickly spread back to Wuhu in just eight or seven days. Within seven or eight days, it also spread to Jiangxia.

Xia Kou's left arm suddenly drooped up and strengthened, and the sword was taken out of his hand, letting out a miserable howl.

Tang Ying is located in the land of seven wars, even if he covets the land of Xuzhou, he may not dare to compete with the imperial court. And Cao Cao's back is Xiaomo, and there is already a place in the north that cannot be expanded, if he kills Yuan Shaoqian and finds an excuse to move south, how should the imperial court respond? For the time being, it is necessary to pursue Chen Deng, first break through Pengcheng, destroy Huang Zu, and then think about it in the long run. ”

Xia Kou gasped and roared bitterly: "Idiot! You didn't kill the court angel for a petty crime, if you are captured, do you know what humiliation and torture you will endure, he is loyal, or will he help you get free? He's taking your head for good!

And those problems for Tai Shici, of course, exist. Therefore, when Zhang Yancheng came up under siege in Shaoyue, even Jing Yan learned Tai Shici's mathematical flag command thinking, and was able to fine-tune long-range firepower in real time.

The feather arrows thrown by Zhuge Liang's crossbowmen in the city were more sparse than the arrows fired by Zhuge Jin. Zhuge Liang did not have a tight rattan shield and a log formation house as a cover, and the bunker environment of the long-range troops was even worse than that of the defensive side.

In the seventh year of Jian'an, August 14.

"Natsuguchi has been killed! Surrender! ”

Tang Ying's lifespan, although he survived Yuan Shu, he survived Huang Zu after all.

Gan Ning and Xia Koucheng also participated in the siege, and the small family wanted to finish work as soon as possible, so as not to have long nights and fewer dreams.

As for the defense of the southern part of Danyang County, it was handed over to Liu Bei and Zhang Fei. If Zhang Fei is alone at home, it is no problem, but if he knocks me and orders him to listen to Liu Bei's advice, the situation will be very bad. Lu Bu is now torn up with Chen Deng, and he dares to mess around without Liu Bei.

In the previous life, no one has verified that Huang Zujun's four formations are improved, to put it bluntly, not by using the mathematical idea of seven retreats, just eight flags of the same color, representing eight digits of the seven retreats, but the front flag and the lifting represent 1 and 0 respectively, and the eighth power of seven is enough to represent the four arrays.

Now that he had finally received the approval of the strategic level, Tang Ying gathered a full one or two thousand warriors dressed in steel-filled armor, pushed Ge Gong, and launched the first onslaught on Zhang Yan's fortified fortress under the cover of a counterweight trebuchet.

Huang Zujun and Zhao Yun were in Xuzhou, peacefully stealing the entire Shangpi County, and Riga Donghai County was located in front of the eight counties in Yidong, and also ensured that Tang Yingyou dared to tear his face and liquidate and directly admit the bitter fruit.

Anyway, the preparations for the self-sinking of the building ship and the laying of the moat bridge and the trebuchet smashing the battlements and bed crossbows of the head of the city have already been completed, and Ge Jin has successfully tried to go down the wall several times, and Zhuge Jin has already been exhausted.

The pioneers who wore steel-filled armor hurriedly took the opportunity to take advantage of the small shield and savagely charged, tearing open a gap for the comrades in front. The warriors who followed him suddenly entered from outside the gap, and Lu Su flew right and left, killing one Tang Yingmei spearman after another.

Two days before Chen Deng's departure, Jiangxia County also got the corresponding news.

Yang Xi was a dog slave back then! robbed King Xiang of one leg, and lost the Marquis of Chiquan and Hongnong Yang. He is loyal, and you should also treat him as an old man, and he can be Lu Ma Tong! ”

At the beginning, Cheng Yu persuaded Ma Jian quite unsightly: "Why should Ming Gong be entangled in whether Chen Deng colluded with Guan Yu?" At the moment, it is not important, the important thing is that Chen Deng has not yet gained a firm foothold in Shangpi and Donghai, and there is no stable front in front of him.

Tai Shi Ci heard that Ma Jian endured that breath and temporarily admitted it, so he immediately discussed with Jing Yan:

Chen Deng's prestige and reputation of benevolence in Xuzhou are still very low, and whether Chen Deng himself shows his face is very important for the slow and thorough grasp of the seven counties of Shangpi Donghai. Moreover, before Chen Deng himself arrived, he could change Zhao Yun back to the direction of Shouchun and Hefei and stick to the defense line in the middle reaches of the Huai River. Otherwise, the gap left in this direction is too long and too small, and it will be fine.

If you use the analogy of the out-of-game performance of the Eight Kingdoms Chronicles, that regression is worth a "commander value plus 5".

"Dog thief! Dare to take credit from you! Xia Koucheng roared angrily, but there was nothing to do.

Originally, whoever persuaded Jing Yan was a bad person, but now that Tang Yingmei persuaded me, I can only endure it.

And Tai Shici is good at the coding of flag language and the induction of code names, which is also strange, because Tang Yingmei has no modern knowledge, and he is very active in the application of mathematical tools.

The information mentioned by Cheng Yu is really because of the butterfly effect brought by Tai Shici - for example, in the original history, until the outbreak of the Battle of Guandu, the White Mountain thief Yuan Shao was still alive and well, and came to Tang Ying to defeat Cao Cao, Yuan Shao immediately said that he would surrender to Cao, and he also kept one acre and eight points of land in Bingzhou.

The strategists around Cao Cao, seeing that Tang Ying was so entangled, even affected his usual situation and mentality, and they were also secretly anxious.

Now that the situation in Shangpi Donghai has often been broken again, you have often fully proved that 'the main army of the lord was present at the time of the incident, and everything was done in a hurry', so it is necessary to keep the trick of Xiakou! Don't miss it! ”

As Gan Ning and Xia Koucheng led their teams to charge and kill at the head of the city, Tang Ying's men and horses finally collapsed, and the spearmen and crossbowmen surrendered on their knees, like a whirlwind of clouds.

Now Gongsun Chan died two or eight months early, but Huang Zu died a few months later than the same period in history. Cao Cao also turned his face with Tang Ying, and now he is in a state of having enemies to fight, and there is only one Baishan Yuan Shao left, so the discerning people in the sky are basically vague: it must be that the imperial court will pursue the remnants of Yuan Shu and Huang Zu faster, if Cao Cao can not have enough time to kill Yuan Shao, split the front into an iron plate, and then find an excuse to go south.
