"Who can tell Gu Ganning why he is in Hefei City!?" Cao Cao asked very lightly and calmly, but it was this surprisingly calm that made the civil and military in the tent look at each other, judging from various intelligence, Gan Ning should also be in the water village of Hengjiang at this moment.

Qiao Ren took advantage of the opportunity of the three fierce generals and Cao Jun's unstable foothold this time, which greatly hit the morale of Cao Jun's southern expedition, so Cao Cao rarely made such a move. In Cao Jun's civil and military hearts, their lord has always been moody and angry, who knows what Cao Cao's calm appearance will be like in his heart, so they all tacitly remained silent. No one knew that at this moment, Cao Cao's mind was drifting through a steady figure and a somewhat unruly prodigal son.

"Prime Minister!" Cheng Yu, the military advisor who accompanied the army this time, had no choice but to speak: "Qiao Ren has renovated Hefei City, and the newly repaired Hefei Outer City has reached the surface of Chaohu Lake, and Gan Ning is probably coming from the waterway!" ”

Oh, yes! The original south gate of Hefei City is still some distance from Chaohu Lake, but Qiao Ren's newly built outer city is based on the original Hefei city wall and built another city wall three miles away, so that Hefei really does the south into the water. Eastern Wu is the overlord on the Yangtze River, and Cao Jun's Xuzhou Navy can't even enter Chaohu Lake, and it is not Wu Jun's final say on the water surface of Chaohu Lake, so it is not surprising that Gan Ning can enter Hefei from the waterway.

Cheng Yu didn't say that it was okay, but when he said it, everyone's confidence in capturing Hefei had decreased a lot. Although the Cao army surrounded Hefei on three sides, the south was always in the hands of the Wu army, and Chaohu was also under the control of the Wu army. Soochow could increase troops, transport supplies, and even withdraw troops by water, and the Cao army could not interfere in any way, which allowed them to attack.

Seeing that Wenwu fell into silence again, Cheng Yu stroked his short beard and said: "The Wu people are just relying on the benefits of the water army, it is better for our army to follow Qiao Ren's example and dig fertilizer water to pour into Hefei." ”

"No!" "No!"

As soon as Cheng Yu finished speaking, two 'no's sounded in the tent, the first one was from Huainan wizard Liu Ye, and the latter was from Sima Yi, a member of the Prime Minister's Mansion. But Cheng Yu is notoriously stubborn, since you all say no, Cheng Yu will definitely ask the truth.

"Why not?" Cheng Yu asked with wide eyes.

Liu Ye stared at Sima Yi, at this moment, he was much higher than Sima Yi in terms of reputation and official position, and he was still a local, so he immediately came out and said, "Cheng Gong." You also know that today's Hefei city has been built by Qiao Renxin, there are two layers inside and outside and Hefei is high in the north and low in the south, if our army diverts water and irrigates, the water can not break through the Hefei city defense, but is introduced into Chaohu Lake by the moat between the two cities. Even if our army can successfully flood the city, the Wu army can also go up the river with the advantage of the water army, which will enhance the strength of the Wu army. ”

"This!" Cheng Yu didn't expect that the back layer, if the water really flooded Hefei, the Wu people's boats could also drive directly on the road, and they were the ones who suffered.

Liu Ye's last reason completely crushed Cheng Yu's strategy, "Besides, it's only February now, and the rainy season will not arrive in a month or two, and the precipitation varies every year, and there are times when the rainy season rains just a little bit." ”

"Well, this plan is not advisable!" Cao Cao unsurprisingly abandoned this plan and asked instead, "Do Ziyang and Zhongda have a plan?" ”

"The minister has a plan!" It was Sima Zhongda who spoke.

Cao Cao was surprised when he heard this: "What's the plan? ”

····························

On the official road to the Lujiang River, a black army is driving rapidly, this army is all black-clothed and black-armored, and even an ordinary person knows that this must be an elite soldier, and the current princes of the Han Dynasty, the Sun family, are gray-clothed and white-armored, Liu Bei is red-clothed and red-armored, and only Cao Cao's troops will be black-clothed and black-armored, so the identity of this army is self-evident, it is Cao Cao's southern expeditionary army.

"The army speeds up! Target Shucheng! Cao Jiangle Jin, who was strong but short in height, shouted loudly, and the soldiers behind him did not respond passionately, but silently accelerated the pace of progress.

······································

"The Grand Duke! The enemy army is ready to storm the city! Before dawn, the dawn slanted from the east, and a pale gold was reflected on Sun Lang's body.

On the east city of Hefei, Qiao Ren, Huang Zhong, Dai Gang and other generals are all here, and Sun Lang is not a Wenchen now, but a serious Hefei Taishou and Dingwei generals, naturally they will also come with soldiers. Except for Sun Shao, who was still recuperating in the city due to the renovation of the troops, and Song Qian and Ding Feng had to guard against the other two city walls, there were many important generals of the Wu army in Hefei.

Although Sun Shao only resisted three or four days in Liyang, the losses were surprisingly large, because he himself fought against 40,000 Qingzhou soldiers with 4,000, half of the 4,000 troops stayed in Liyang and could not stand up again, even the remaining 2,000 people were almost all wounded, can such a force not be repaired? However, his record is also amazing, defeating Xiahoudun's attack with only 4,000 people, and destroying nearly 5,000 enemies, which can already be said to be a victory.

'Woo woo' Cao Jun's horn resounded through the world. To the northeast, facing the dazzling sunlight, it was black, and the 40,000 Cao army began to attack the city at this time. The 30,000 Cao troops in front of the Shengcheng troops marched neatly and swarmed in. And in front of them were dozens of huge wooden frame machines.

Thunderbolt ------- if it had been a heavyweight siege attack last year, it might have put some pressure on Hefei, but now I'm afraid it's just cannon fodder.

"Good morning obedience! Let Cao Jun taste the benefits and disadvantages of cannons (ballistas)! Qiao Ren had disdain in his eyes, the times are changing, and it is impossible for a thunderbolt to dominate an era.

"Whoa!"

Outside the city wall, the soldiers of Cao pushed the thunderbolt cars one after another, and the soldiers of the Wu army on the city wall were manipulating the ballistas and bed crossbows one by one to adjust the Zhu Yuan.

The attack range or range of the catapult is only 500 meters, which can be said to be a long-range attack weapon at that time, but it is much worse than the bed crossbow made by the Wu army with the technology of the Song Dynasty, and the best range of the bed crossbow can reach 1,000 meters, even if the range is shorter, the ballista has a range of 500 meters, and the accuracy is not the same. This is not counting the situation of the Yokoe shooter, the range of the Yokoe shooter can reach three hundred and sixty meters, which is about 100 meters worse than the catapult, and the Yokoe shooter is beyond the reach of the catapult in terms of launch speed and accuracy. Hefei has such long-range lethal weapons and troops, what role can Cao Jun's catapult do?

A quarter of an hour later, Cao Jun's thunderbolt finally entered the range of the bed crossbow, but Wu Jun on the city tower still did not react, a hundred meters, two hundred meters, the thunderbolt slowly advanced, as the city governor Zhang Liao's face slowly smiled.

"Thunderbolt forward!"

"Bed crossbow shooting! Ballista ready! Almost at the same time, Sun Lang on the city wall also shouted loudly.

Because Sun Lang has the duties of Hefei Taishou, his troops are mainly based on city defense training, in other words, they are mainly trained in ballistas and bed crossbows, and they have become artillery units in later generations, they are professional!

"Bang!" With a loud bang, it is difficult to imagine such a picture in ancient battles, dozens of bed crossbows fired at the same time, hundreds of giant crossbow arrows pierced the resistance of the air, and countless ballistas aimed at the later generations of Mark Qin on the wooden frame. Cao Jun has never seen such a city guard.

A black shadow was overwhelming, although it was only a hundred crossbow arrows, but in the eyes of the Cao soldier who operated the catapult, it was almost equivalent to overwhelming. No one thought that this place nearly 600 meters away from the city would suffer from the baptism of arrow rain, you must know that the thunderbolt car can play well and can hit a distance of 600 meters, Cao Jun collapsed what was faith.

At such a distance, there are crossbow arrows, and even if you get to the bottom of the city, there are rolling stones and logs, and the smile at the corner of Zhang Liao's mouth is not far away····· Stiffened.
