Jiang Wei successfully took Hedong, and began to deploy to Shangdang County, Sima Yi blocked Liu Yi from transferring the soldiers and horses of Bingzhou, and now there are not many defenders in the counties in Bingzhou, most of them are temporary signs of militia to defend the city, these militias, barely able to defend the city, but really in the face of the Han army's strong long-range attack, it can't hold on, often after Jiang Wei's three rounds of arrow rain shoots, most of the defenders have begun to collapse.

In terms of the quality of the generals and the soldiers, the troops assembled in Bingzhou can really only be regarded as a rabble, and Jiang Wei also chooses to fight steadily and steadily, every time he goes to the next city, he first appeases the people, sorts out the internal affairs, and waits until the officials sent by the imperial court take over, and then continue to attack the next city.

This is also Liu Yi's strategy, it can be defeated, but the city occupied, even if the main force is defeated, is still ours, and the other is to liquidate the official land and private land, and confiscate all the private land of the recalcitrant family, as the official field, of course, the family who is willing to surrender cannot be killed with one shot, at least to ensure the legitimacy of their property, otherwise if all the private land is confiscated, I am afraid that it will really have to be defeated city by city.

It may be difficult at first, but after Hedong was completely captured, the resistance of the Shangdang was much weaker than that of Hedong, and the Wei court now gathered heavy troops to fight Liu Yi with all its might, and there was no spare energy to pay attention to the annexation, and it also gave Jiang Wei enough time for him to continue to devour the annexation of the prefecture little by little.

However, the battlefield of Bingzhou is only an auxiliary, and it is naturally best to be able to lead part of the Wei Dynasty's troops, if not, at least 10,000 soldiers and horses are enough to take down the current empty garrison of Bingzhou, and even threaten the area of Daijun.

The state is mountainous, strategically speaking, it is not a battleground, but if the state can be taken, the west of the Taihang Mountain will become the territory of the Han Dynasty, and Cao Wei will face a situation where there is no danger to defend, as long as the state is taken, the initiative of the war will completely fall into the hands of the Han.

Time was in the confrontation between Liu Yi and Sima Yi re-formed, and when it came to July, Liu Yi did not attack rashly, he was worried about Sima Yi's way.

And Sima Yi did not attack, but stepped up the layout of the defensive line, the war in the south is not optimistic, and all that came back was the news of Cao Shuang's defeat and retreat, but Cao Shuang was not really an idiot, and took the initiative to give up Guangling and Jiujiang, in this way, it seemed to lose territory, but it invisibly stretched the front of the Han army, so that the numerical advantage of the Wei army could play a role, and more importantly, the entire Pang Tong Department was sandwiched between Eastern Wu and Cao Wei.

Although there has been no movement in Soochow so far, Pang Tong obviously has to worry about the back, and he can't deal with Cao Shuang with all his might, so that Cao Shuang has a little respite and can be deployed calmly.

It's just that during this time, Liu Cheng's attack was more ferocious, not only did he win a part of Nanyang County controlled by Cao Wei, but also held all the cities west of Runan County and Shangcai in his hands, and began to try to seek a decisive battle with Cao Shuang.

"Liu Yi's son, it's not simple!" Yanjin, Sima Yi's tent, looking at the battle report from the south, Sima Yi shook his head a little bitterly and sighed.

From the beginning of the army, although Liu Cheng belonged to Pang Tong, he always led an army by himself, and when the strength was not superior, and it could even be said that he was outnumbered, he was on a par with Cao Shuang, who had the advantage of the home field, and this young man, who had just won the championship, showed a talent for war, but it was enough to embarrass many famous generals.

Now he has a tacit understanding with Pang Tong, takes the initiative to take on the offensive task, and oppresses Cao Shuang in the area of Dingying, so that Cao Shuang cannot deal with Pang Tong with all his strength.

It's really not like him at all!

"Father, then Liu Yi ......" Sima Shi didn't care much about Liu Yi's son, he cared more about Liu Yi now.

"What's wrong with him?" Sima Yi frowned and said, somehow, as soon as Liu Yi was mentioned, he had a headache.

"According to the detailed report, Liu Yi is now building a factory in Hanoi, as well as wooden rails, digging ditches to divert water to irrigate the fields, digging a river channel connecting the big river in Huai County and the area of the shooting dog, and building a waterwheel......" Sima Shi rubbed his temples and said with a wry smile: "The child really doesn't know what this Liu Yi wants?" ”

"Engage in internal affairs and restrain the people's hearts." Sima Yi shook his head and smiled bitterly: "He's going to continue to consume with us!" ”

"What's in it for him?" Sima Shi was puzzled.

"Because he was not sure that he would be able to defeat us, he chose to take it step by step, to consolidate the rear, to make the grain route clear, and to bring the people's hearts together." Sima Yi sighed and said: "This is also where our weakness lies, my father is not afraid of his clever plans, the most worrying thing is that he uses this method to hold on to our army, the war in the Central Plains is not good for our army, Cao Shuang is not the enemy of Pang Tong, the longer it drags on, the more unfavorable it will be to our dynasty." ”

Da Wei, I can't afford it!

But when it comes to attacking, Liu Yi has no confidence to defeat Sima Yi, worried about being yin, but Sima Yi is also powerless in the face of the towers and arrow towers built by Liu Yi's camp, after the Han Dynasty has cultivated for many years, the range of the bow and arrow seems to have improved a lot, and Sima Yi has carefully studied several camps set up by Liu Yi, in this regard, Liu Yi is definitely the top existence in the world, which can be called a drop of water, if you want to attack, you can only attack.

The camps are horns between each other, and it is impossible to make a detour, but if it is directly attacked, the Wei army is afraid that it will suffer heavy losses.

"Father, I have a plan, maybe I can break through the enemy camp!" Sima Shi thought for a moment and looked at Sima Yidao.

"Oh?" Sima Yi looked at Sima Shi.

"Father, do you still remember that when Taizu fought Yuan Shao in Guandu, Yuan Shao used digging tunnels with diggers?" Sima Shi thought for a while and said: "We can dig a tunnel from Yanjin, although it takes a long time, but it is not easy for the Han army to detect the ground in the city." ”

Sima Yi thought for a while, nodded and said, "Maybe you can give it a try!" But the plan had to change. ”

"Father, please!" Sima Shi bowed and said.

"Let's dig the tunnel first, it's not a day's work!" Sima Yi shook his head and smiled.

"Whoa!"

At that moment, Sima Shi received the order, and then gathered a thousand soldiers in the city to start digging tunnels, he specially invited Ma Jun to help this time, and Ma Jun calculated the direction, and then the soldiers excavated.

In this way, three days later, Liu Yi was designing a waterwheel in Huai County, but suddenly received a summons from Wei Yan and asked Liu Yi to come over.

"What happened?" Liu Yi took the wet wipes handed by Ma Qiu and wiped his sweat, the weather in July is really terrible.

"Governor, the geodynamic instrument you left behind has been a little abnormal these days, and the last general doesn't know what happened, so please come and see it." Wei Yan arched his hand at Liu Yi.

"Geokinesis?" Liu Yi stared, nodded and said, "Take me there!" ”

"Whoa!"

Liu Yi's geodynamic instrument is not large, it is a simple measuring device, but the sensitivity is not low, Wei Yan took Liu Yi to the tent of the geodynamic instrument, and saw the soldiers returning the mechanism of the geokinetic instrument.

It's just that after a while, the bracket fell again.

"Sikong, the river water hasn't changed recently, is this geokinetic instrument broken?" Wei Yan looked at Liu Yi and asked.

"It's not broken!" Liu Yi shook his head, whether the ground motion instrument was bad or not, he could see it at a glance.

"Ordinary exercises, the ground motion instrument has no response, this is ...... Could it be that the earth dragon turned over? Wei Yan said suddenly.

"If the earth dragon turns over, how can you wait for me to come?" Liu Yi said with a smile, the earth dragon turned over, it was an earthquake, if it was really an earthquake, Huaixian should also be able to sense it.

"I'm afraid that Sima Yi is playing some tricks again." Liu Yi looked at the ground motion instrument, thought about it, listened to it with a bamboo tube, and after listening carefully for a while, he sneered: "Someone is digging a tunnel." ”

"Impossible!" Wei Yan shook his head and said, "There are scouts sent to investigate within a radius of dozens of miles, if someone digs a tunnel, how can they not know?" ”

"No, we can't find out inside the city!" Deng Ai said suddenly.

"In the city?" Wei Yan frowned and said, "This place is more than ten miles away from Yanjin!" ”

"It's not too long!" Liu Yi shook his head and smiled: "I'll take a look!" ”

At the moment, Liu Yi made several ground earpieces, put them down in different positions, and moved the ground motion instrument to test everywhere, and after leaving the camp for two or three miles, the ground motion instrument did not respond.

"It's really right to be said by Shi Zai, Sima Lao Thief is going to be a local rat!" Liu Yi said with a smile.

"If it's authentic, the last general has his own way to deal with it." Wei Yan laughed when he heard this.

"Governor, general, the last general has a good idea, why not take this opportunity to lead that Sima Lao'er to send troops and defeat him for a while?" Deng Ai suddenly said to the two of them.

Liu Yi's eyes lit up when he heard this, and he turned his head to look at Wei Yan: "What does Chief Wen think?" ”

At present, Sima Yi has an army of more than 200,000 people, and it is impossible to defeat him in one battle, but since the other party has made a move, it is also excellent to defeat him for a while and frustrate the opponent's spirit.

Wei Yan pondered: "It's okay, but I don't know when the other party will be able to dig it up." ”

More than ten miles of tunnels, Wei Yan didn't know whether to praise Sima Yi for his perseverance, or scold him for being naïve.

"Be careful, Sima Yi can be said to be resourceful and not to be underestimated!" Seeing that Wei Yan agreed, Liu Yi didn't ask anymore at the moment, just nodded and smiled.

"Don't worry, the last general knows what to do!" Wei Yan bowed and said.

"It's good to know, in this way, you stay in the main camp, and I will take Ma Qiu and Pang Hui to the side camp to garrison, if there is an accident, send a letter immediately!" Liu Yi thought about it, but he still felt that it was not very safe, and it was a bit risky, after all, the opponent was Sima Yi, and this kind of strategy was not a set of combos, right?

"The governor will go by himself, and the last general will definitely call the Wei army to come and go!" Wei Yan said with a smile.

At the moment, everyone had decided to discuss it, Liu Yi was not in a hurry to return to Huaixian, and took Ma Qiu and Pang Hui to a large camp to station, after all, he was still a little uneasy in his heart, but since he agreed to let Wei Yan preside over the overall situation, Liu Yi was not good at interfering, which would easily cause chaos in the management of the army, he could only prepare for the worst, if Wei Yan was on the road, he would be here, and he could also remedy it as soon as possible!

I hope it's my own heart.

When leaving the camp, Liu Yi glanced back and always felt that since Sima Yi made a move, it would not be so simple.
