Jiang Wei successfully captured Hedong and began to deploy Shangdang County. Sima Yi blocked Liu Yi and transferred Bingzhou troops. Now there are not many garrisons in Bingzhou. Most of them are temporary signs of militia to guard the city. These militias can barely defend the city, but when they really face the powerful long-range attacks of the Han army, they can't hold on. Often, after Jiang Wei's three rounds of arrows shot, the defenders probably began to collapse.

Whether in terms of generals or soldiers' quality, the troops gathered in Bingzhou can only be considered a mob, and Jiang Wei also chose to fight steadily. Every time he sets a city, he first appeases the people's hearts and sorts out the internal affairs. After the officials sent by the court take over, he will continue to attack the next city.

This is also Liu Yi's strategy. He can be defeated, but even if the main force fails, it is still ours. In addition, he must clear the official land and private land. All the private lands of the stubborn families are confiscated. As official land, of course, the aristocratic families who are willing to surrender cannot be killed in one stroke, at least to ensure the legality of their property. Otherwise, if all the private lands are confiscated, they will be really conquered.

It might be difficult at the beginning, but after Hedong was completely captured, Shangdang's resistance was much weaker than Hedong. The Wei court has gathered heavy troops to fight with Liu Yi with all his might, and has no spare energy to pay attention to Bingzhou. It also gives Jiang Wei plenty of time for him to swallow Bingzhou bit by bit.

However, the Bingzhou battlefield is only an auxiliary, and it is naturally the best to be able to pull some of the troops of the Wei Dynasty. If not, at least ten thousand troops will be enough to take down Bingzhou, which is currently empty, and even threaten the Dai County area.

Bingzhou is mountainous, and strategically it is not a place to fight. However, if Bingzhou can be taken, it will become the territory of the Han Dynasty west of Taihang Mountain, and Cao Wei will face a situation where there is no danger to defend. As long as Bingzhou is taken, the initiative in the war will be completely in the hands of the Han Dynasty.

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

Sima Yi did not launch an attack, but stepped up the deployment of defense lines. The war in the south was not optimistic, and all the news came back were news of Cao Shuang's retreat. However, Cao Shuang was not really an idiot, and took the initiative to give up Guangling and Jiujiang. In this way, it seemed that he had lost his territory, but invisibly extended the front line of the Han army. In this way, the number of troops of the Wei army could play a role. More importantly, the entire Pang Tong army was sandwiched between the Eastern Wu and Cao Wei.

Although there has been no movement in Eastern Wu so far, Pang Tong obviously has to worry about being unable to deal with Cao Shuang with all his strength, which gives Cao Shuang some chance to breathe and can make arrangements calmly.

However, during this period, Liu Cheng's attack was quite fierce. Not only did he get a part of Nanyang County controlled by Cao Wei, but he also held all the cities west of Runan County and Shangcai in his hands, and began to try to seek a decisive battle from Cao Shuang.

"Liu Yi's son, it's not simple!" Sima Yi shook his head and sighed bitterly in Yanjin, looking at the war reports coming from the south.

Since the start of sending troops, although Liu Cheng belonged to Pang Tong, he always led his own army. When the troops were not superior, it could even be said that the enemy and us had a huge gap, he played a match with Cao Shuang, who had the home advantage. However, the young man had just reached the championship, and the war talent he showed was enough to make many famous generals ashamed.

Now he cooperates with Pang Tong and takes the initiative to take on the offensive task. He oppresses Cao Shuang in the Ying area, making Cao Shuang unable to deal with Pang Tong with all his strength.

Really, he doesn't look like him at all!

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

"What's wrong with him?" Sima Yi frowned. Somehow, he had a headache when he mentioned Liu Yi.

"According to detailed reports, Liu Yi has now built a factory in Hanoi, and has wooden tracks, digging ditches to divert water to irrigate the fields, and dug a river channel connecting the big river in Huai County and Shequan to build a water truck..." Sima Shi rubbed his temples and smiled bitterly: "I really don't know what Liu Yi wants to do?"

"Treat internal affairs and conquer the people's hearts." Sima Yi shook his head and smiled bitterly: "He is planning to continue to waste time with us!"

"What is the benefit of this?" Sima Shi said in confusion.

"Because he was not sure that he could defeat us, he chose to take every step of the camp, consolidate the rear, make the food route usually, and make the people's hearts surrender." Sima Yi sighed and said, "This is exactly the weakness of ours. I am not afraid of his own tricks. What I worry most is that he uses this method to stalemate 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 for our court."

The Great Wei cannot afford to consume it!

But when it comes to attack, Liu Yi was not confident of defeating Sima Yi and was worried about being under the slightest. However, Sima Yi was unable to do anything to face the tower and arrow tower built by Liu Yi. After the Han Dynasty's cultivation over the years, the range of the bow and arrow seemed to have improved a lot. Moreover, Sima Yi carefully studied several camps set up by Liu Yi. In this regard, Liu Yi is definitely the top presence in the world and can be said to be invisible. If you want to attack, you can only attack forcefully.

The camps are mutually supportive, and it is impossible to take a detour, but if they attack directly, the Wei army may suffer heavy losses.

"Father, I have a plan that may break through the enemy camp!" Sima Shi thought for a while, looked at Sima Yi and said.

"Oh?" Sima Yi looked at Sima Shi.

"Does my father still remember that when Taizu fought against Yuan Shao in Guandu, Yuan Shao used ground digging tunnels?" Sima Shi thought for a while and said, "We can dig an authentic tunnel from Yanjin. Although it took a long time, it would not be easy for the Han army to detect when we started digging ground in the city."

Sima Yi thought for a while and nodded, "Maybe you can try it out! But the plan needs to change."

"Please tell me my father!" Sima Shi bowed and said.

"Digging the tunnel first, this is not a day's effort!" Sima Yi shook his head and smiled.

"Here!"

At that moment, Sima Shi received the order and summoned thousands of soldiers to dig tunnels in the city. This time he specially invited Ma Jun to help, Ma Jun calculates the location, and then the soldiers excavated.

In this way, three days later, Liu Yi was designing a water truck in Huai County, but suddenly received a message from Wei Yan, asking Liu Yi to come over.

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

"Governor, the seismometer you left behind is somewhat abnormal these days. I don't know what happened. Please ask Sikong to come and see it." Wei Yan bowed to Liu Yi.

"Earthrotor?" Liu Yi's eyes narrowed and he nodded and said, "Take me there!"

"Here!"

The seismometer made by Liu Yi was not big, it was a simple measuring device, but its sensitivity was not low. Wei Yan took Liu Yi to the seismometer tent and saw the soldiers returning the mechanism of the seismometer.

But after a while, the mechanism fell off again.

"Sikong, the river water has not changed recently. Is this seismometer broken?" Wei Yan looked at Liu Yi and asked.

"It's not broken!" Liu Yi shook his head. Whether the seismometer is broken or not, he could tell at a glance.

"Even the ordinary exercise, the seismometer did not respond. Is this... Could it be that the earth dragon turned over?" Wei Yan said suddenly.

"If the earth dragon turns over, how can I wait until I come?" Liu Yi said with a funny look. Even if the earth dragon turns over, it would be an earthquake. If it really is an earthquake, Huai County should be able to sense it.

"I'm afraid Sima Yi is playing something again." Liu Yi looked at the seismometer, thought for a while, listened with a bamboo tube, and after listening carefully for a while, he sneered: "Someone is digging tunnels."

"Impossible!" Wei Yan shook his head and said, "The generals within a radius of dozens of miles have sent scouts to investigate. If someone digs a tunnel, how can he not know?"

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

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

"It's not long!" Liu Yi shook his head and smiled, "Let's talk about it after I take a look!"

At this moment, Liu Yi made several earpieces, put them down at different positions, and moved the seismometer to various places for testing. After two or three miles away from Daying, the seismometer did not respond.

"Shizai really said it right. Sima's old thief wants local rats!" Liu Yi said with a smile.

"If it is authentic, I will have my own way to deal with it." Wei Yan smiled when he heard this.

"Governor, general, I have a good idea. Why not take this opportunity to lead the Sima old man to send troops and defeat him?" 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 do Wen Chang think?"

Sima Yi now has more than 200,000 troops, and it is impossible to defeat him in one battle. However, since the opponent has made a move, it is also excellent to defeat him for a while and to dampen the opponent's spirit.

Wei Yanshuo said, "But it's possible, but I don't know when the other party will be able to dig it up."

Wei Yan didn't know whether to praise Sima Yi for being perseverant or scold him for being stupid.

"Be careful, Sima Yi is a resourceful person and should not be underestimated!" Seeing Wei Yan's agreement, Liu Yi stopped asking about it now, just nodded and smiled.

"Don't worry, the governor, I know what to do!" Wei Yan bowed and bowed.

"It's good to know, so you stay in the main camp. I'll take Ma Qiu and Pang Hui to the side camp to guard. If there is an accident, send a letter immediately!" Liu Yi thought about it, but he still felt that it was not safe and he was a little risky. After all, his opponent was Sima Yi. Is this strategy not a set of combos, right?

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

At this moment, everyone had decided to discuss it, and Liu Yi did not rush to return to Huai County and brought Ma Qiu and Pang Hui to a large camp. He was still a little worried after all, but since he agreed to let Wei Yan take charge of the overall situation, Liu Yi would not be able to interfere anymore. This could easily cause chaos in the military management. He could only make the worst plan. If Wei Yan said that he could make up for it as soon as possible!

I hope I am too concerned.

When leaving the camp, Liu Yi looked back and always felt that since Sima Yi took action, it would not be so simple.
Chapter completed!
