Cao Pi waved his hand and said, "Okay, without further ado, let's go and prepare quickly, Zhongda, Zidan, you guys move quickly!" ”

"No!" The courtiers withdrew.

Everyone left, but Cao Zhen stayed, and he asked Cao Pi: "Your Majesty, you are not feeling well, why do you drive the expedition in person?" And Sima Yi, didn't the first emperor let you use it with caution? Why did you still let him ......?"

Cao Pi waved his hand and said: "Since Zhuge Liang has premeditated, whether he can recapture Longyou this time is still two words, so I must drive the expedition in person to boost morale, if Zhang He and Sima Yi are defeated, and the Shu army takes advantage of the situation to kill Guanzhong, how is it good?"

As for Sima Yi, although the first emperor asked me to use it carefully, he also said that as long as Shu was strong, Sima Yi would not dare to betray, and I was worried that Zhang He was not Zhuge Liang's opponent, so I sent Sima Yi to go with him, and he was only given a position to join the army, giving advice, not being in charge of the army, you don't have to worry.

Zidan, the situation is critical at the moment, and you still need to return to Guanzhong as soon as possible. ”

Cao Zhen bowed his hand and retreated: "The last general will go and prepare!" ”

When Sima Yi returned home, he immediately packed up, and then led dozens of horsemen and horses to Chang'an.

Sima Yi passed through the post station all the way to change horses, and it only took one day to arrive in Chang'an.

After arriving in Chang'an, Sima Yi announced Cao Pi's will.

Zhang He received the holy decree and consulted with Sima Yi.

Zhang He said to Sima Yi: "Zhongda, after Zhang Ren left the valley, he has been stationed in Wuzhangyuan and has not moved, if he wants to attack Guanzhong, he should fight quickly, it is impossible to stand still." In this way, Zhang Ren was just bluffing, and he didn't have many soldiers, and it was to respond to Zhuge Liang's actions. ”

"Heroes see the same thing!" Sima Yi nodded and said, "How long has it been since Zhang Ren sent troops?" ”

Zhang He replied: "It has been more than ten days since I left Qishan. ”

Sima Yi muttered: "Qinchuan is difficult to do, Zhuge Liang and Zhang Ren sent troops at the same time, Zhuge Liang should be the first to go out of Qishan, so Zhuge Liang has been out of Qishan for at least half a month, and he needs to do it as soon as possible. ”

Zhang He said with a bitter face: "If you go to Meixian County to attack Zhang Ren, you can set off in three days, but to go to Jieting, you have to walk a mountain road, and there must be soldiers and horses stationed in Jieting, as an attacker, we have to prepare a lot of things, so it will take ten days at the earliest." ”

Sima Yi sighed and said: "Ten days to prepare grain and grass, from Chang'an to Jieting, it will take seven days at the earliest, Zhuge Liang should have been out of Qishan for half a month, so when our army arrived at Jieting, Zhuge Liang has been marching into Longyou for more than a month, I hope that the counties of Longyou can support it for more time."

Otherwise, Yongliang will not be at peace for ten years. ”

"Hmm......" Zhang He also took a deep breath, and his heart was a little heavy.

Ten days later, the grain and grass of the 50,000 army were ready, Zhang He was the main general, Sima Yi joined the army, and the two led 50,000 soldiers and horses, and ran to the street pavilion.

And Cao Zhen has also arrived in Chang'an with 20,000 soldiers and horses under the division at this moment, and Cao Pi is also in Luoyang to explain government affairs in full swing, preparing to drive to Chang'an in person.

When Zhang He and Sima Yi set off from Chang'an, Deng Ai also arrived at Jieting and set up camp in Jieting.

On the road between the two mountains, a camp rises from the ground, and the two sides of the camp are connected to the two mountains, as if a city wall is in the middle of the road.

However, this road is a bit wide, as long as a mile, so this camp is the scale of a mile radius, Deng Ai soldiers and horses only have more than 10,000 people, such a scale of the camp, at least 30,000 or 40,000 people, so it seems a little empty.

Deng Ai stood at the gate of the camp, pointed to the mountains on both sides and said to the adjutant general: "On these two mountains, each will have a thousand archers, build more arrow towers, and deploy strong bows and crossbows. In addition, this trip brought a lot of craftsmen, and divided 500 soldiers to cut down trees in the rear to build a return cannon, which did not need to be as powerful as the imperial court system, but it was also worthy of the imitation return cannon of the Wei State. ”

Wang Ping said worriedly: "General Deng, our army is already short of soldiers and horses, if we divide 500 people to build a return artillery, the soldiers in front of this battalion will be even more sparse." ”

Deng Ai said with a smile: "The surrounding mountains and forests are lush with trees, and materials are readily available, so the construction of the return cannon will not be delayed for a few days." The Wei army came from afar, even if there were no five hundred people, they would not be able to take the camp, and now they would use these five hundred people to build the return artillery, and after the return cannon was built, it would be worth 10,000 troops.

Sharpen the knife without cutting firewood, and use the right method in everything, you can get twice the result with half the effort. ”

Wang Ping nodded and agreed with Deng Ai's point of view: "Yes!" ”

Deng Ai looked at the wide road ahead and said: "Now that the Wei army has not arrived, we should destroy the road and set traps, even if it can delay them for a day, it is good, let the brothers cut more bamboo to make bamboo thorns." The rest of the men grabbed their tools and went to dig the traps. ”

Deng Ai led the soldiers and horses out of the camp and commanded the soldiers to set traps on the way ahead.

Wang Ping watched a few soldiers dig the trap and do something hastily, and couldn't help but say: "After setting the trap, you must destroy the traces on the ground, otherwise you will see it at a glance." ”

Deng Ai stepped forward and said, "Brother Zijun, the soil of this road is relatively hard, and after digging the trap, even if you hide it carefully, you can see some clues.

It's better to hide casually, or even deliberately mark it, and let them clear it one by one, so as to delay more time.

If all the real traps are set up, the Wei army can see at a glance by relying on the traces on the ground, so as to make a detour, and the traps we make will be useless. ”

Wang Ping's eyes lit up: "This is a good strategy, let's deliberately dig around, some set up real traps, some set fake traps, let them eliminate them one by one, so as to delay more time." ”

Deng Ai said with a smile: "Just have one truth in the ten voids, there is no need for any rules, let's start from the front and arrange it all the way to the camp." ”

Deng Ai led people to dig on the mountain road for three days, and after three days, the streets and avenues, the twenty-mile road, were full of potholes, as if they had been renovated, and some places were even watered, the land was trampled into mud, and it was difficult for heavy vehicles to pass.

At this moment, Zhang He and Sima Yi finally led their troops to the range of the street pavilion.

Zhang He sent scouts to inquire about the situation of the Han army.

But it didn't take long for a group of scouts to return.

Two soldiers were still carried back, only to see a big hole in the back, which seemed to have been pierced by bamboo thorns.

The scout said to Zhang He with a disgraced face: "General, the road ahead is full of traps, and I waited for a few steps before I fell into the trap, and the war horse also stepped into the trap. ”

Zhang He frowned and scolded: "Digging traps on the ground, you can see at a glance, as scouts, don't you even have this eyesight?" ”
