Sima Yi was very worried about the future situation, he had seen Cao Cao's good intentions back then, but even if he understood many things, it was too difficult to change.

The national policy of the Great Wei has been decided, if you want to change it at this time, this resistance is not ordinarily big, it is not from foreign enemies, no matter how strong the Han is, the soldiers will block, and the water will come to the earth, there is always a way, the real problem, in the Great Wei own national policy itself, does not support the construction, and even because Cao Cao was overwhelmed by the public opinion back then, now without Cao Cao, the craftsmen in the Great Wei have been suppressed a lot, and many craftsmen have thrown themselves to Soochow or the Han Dynasty.

After all, whether it is Eastern Wu or the Han Dynasty, they are now focusing on improving the status of craftsmen in the national policy, not to mention the Han Dynasty, there is Liu Yi, the world's first craftsman, who is in a high position in the middle of the court, and Liu Bei himself and even Zhuge Liang, Pang Tong, Guan Yu, Zhang Fei, these high-level civil and military have a supportive attitude towards Xinggong.

In recent years, Dongwu has continued to buy many sophisticated equipment of the Han Dynasty, and when fighting against Cao Jun, he also tasted the sweetness, while imitating the equipment of the Han Dynasty, on the other hand, he will also improve the treatment and status of craftsmen, and form his own team of craftsmen.

But the Great Wei wanted to restart the construction regulations set by Cao Cao that year...... Difficult!

"General, our army has repelled Guan Yu, why are you worried?" Le Qi came to restore his life, and when he saw Sima Yi's demeanor, he was a little puzzled.

Sima Yi sighed, shook his head and said: "Thinking of some past events, don't care, although Guan Yu is temporarily retiring, he will not leave just now, so let the soldiers be on guard." ”

Le Qi smiled: "With this batch of equipment, why be afraid of the Han army? ”

"Yes." Sima Yi nodded, didn't say much, but this thing is just the tip of the iceberg, the Han army is afraid that the equipment of the armies will not be too bad, they are equipped with these, and they are only on par with the Han army in terms of equipment, and they are only equipped with 3,000 people so far, it is really head-on, but it is not as optimistic as now.

On the other side, Guan Yu retreated and set up camp, this was probably the first time that the Han army personally faced the weapons made by Liu Yi, and it felt really not very good.

"Order Liao Hua to mobilize a group of catapults and bed crossbows from Yique Pass." After sulking for a long time, Guan Yu also knew that with Sima Yi's law-abiding, it was difficult to break through the camp without using siege equipment, although there were also Liu Yi's disciples in the army, but the ordnance made could not be compared with what Liu Yi made, whether it was in range or power, it was much worse.

"Whoa!" A personal guard said yes and went to give the order.

Zhou Cang looked at Guan Yu with some concern and said, "Junhou, it will take at least three days for this siege equipment to be transported from Yique Pass!" ”

If it is a weekday, three days of time, naturally it is nothing, they can afford to wait, but the grain and grass in the army can only support three days, after three days, whether it is Yique Pass or Guan Yu here, they will fall into the dilemma of having no food available, so there is not so much time for them to wait slowly.

Guan Yu nodded when he heard this, he didn't know the reason, but if he didn't use siege equipment, if he wanted to break the camp, he had to take people's lives!

Guan Yu has an arrogant personality, but he takes care of the soldiers, and he naturally doesn't want to play like this.

"Let the sappers in the army start making equipment." Guan Yu sighed, since the quality can't meet expectations, let's use the quantity to pile it up now, the Han army is going out this time, and among each army, there is an engineer team, commanded by one of Liu Yi's disciples, it is precisely to deal with some situations where Liu Yi is not there, and it is necessary to build some siege equipment or city defense facilities, Guan Yu naturally wants to use the best, but the current conditions do not allow it, so he can only retreat.

"Prince!" A general suddenly came in from outside the tent and said to Guan Yu: "There is a messenger from Mohou asking to see you!" ”

"Oh?" When Guan Yu heard this, his eyes lit up, and he hurriedly said, "Please!" ”

"Whoa!"

After a while, Guan Ping, who was dressed in dust and dust, came to Guan Yu's tent, in fact, Guan Ping had rushed to Yique Pass yesterday, but Guan Yu had already led the army to go out at that time, Guan Ping did not care about Liao Hua and Yi nationality, and chased after him overnight, in fact, this kind of thing is just to communicate with each other, just send a messenger to come, but Guan Ping was worried about his father's safety, so he came in person, just to make sure that Guan Yu was safe.

"Tanzhi?" Guan Yu looked at Guan Ping with some surprise and said, "Why are you here?" ”

"Hearing that his father was in danger, Ping Te asked Mohou for his life." Guan Ping saw that Guan Yu was unharmed, and said with relief in his heart.

"As a general, how can you abolish the public for personal reasons?" Guan Yu snorted coldly.

"It's Mohou who sent the child." Guan Ping hurriedly explained that if Liu Yi didn't let him, with Guan Ping's character, no matter how uncomfortable he was, he would definitely not disobey the military order.

When Guan Yu heard this, his expression softened a little, he has been friends with Liu Yi for more than ten years, if his son came because he ignored Liu Yi's military orders, even if Guan Yu valued Guan Ping the most, he would never tolerate it.

"You go back quickly and tell Bo Yuan that the Wei army is trapped here for Hangu Pass, so don't move lightly!" Guan Yu said in a deep voice.

"Mo Hou has already guessed." Guan Ping shook his head and said: "Father, don't worry, Mohou has found another way, yesterday has sent someone from Yishui to send a batch of grain and grass to Yique Pass, but although this road can lead to Nanyang, but the road is difficult and the mountain road is complicated, if the military rations are sent from Nanyang, I am afraid that the consumption will be long-lasting, and the military rations of Hanguguan can not supply the two armies." ”

"Let Bo Yuan not have to be embarrassed." Guan Yu sighed, Liu Yi was already very grateful that he could do this.

Guan Ping shook his head: "Mohou has ordered the unrelated, Shangyong and other places to increase the delivery of grain and grass, but it will take at least a month to arrive, but the grain and grass sent this time is only enough to support seven days." ”

"Seven days is enough!" When Guan Yu heard this, his eyes lit up, so he didn't need to use his life to add it, and said immediately: "You go back and tell Bo Yuan, so that he doesn't have to worry about this place, just Sima Yi, if you want to cut off my way back, it's not qualified enough!" ”

"That's why Mohou is here." Guan Ping smiled bitterly and said: "Mohou warned the child that Sima Yizhi's ability is comparable to Prime Minister Zhuge Cheng, let his father deal with it carefully!" ”

"Oh?" When Guan Yu heard this, he was a little surprised, he didn't expect Liu Yi's evaluation of Sima Yi to be so high, it was not good to say anything big now, in fact, he fought with Sima Yi before, and he did have a difficult feeling.

"Bo Yuan asked you to come here, do you have any strategies?" Guan Yu asked suddenly.

"Mohou does have an explanation, if Sima Yi is in Luoyang, then you can't move lightly, if Sima Yi is in Yang, you can let the child replace the father, pretending to be the father here, and the father will turn back to Yique Pass, try to break Cao Xiu first, although Cao Xiu is outnumbered, but the elite of the Wei army is probably still trying to ambush Mohou in the Gucheng area at this moment, if the father can break Cao Xiu and take advantage of the weakness to seize Luoyang, then the siege of the Cao army can be broken by itself!" Guan Ping bowed.

This is also a loophole that Sima Yi arranged this time, Cao Xiu should have been the strongest, but because of this, it has also become the deadliest place, if Cao Xiu can be defeated, Liu Yi guessed that Luoyang may not have many troops at the moment, if Guan Yu can take advantage of the situation to seize Luoyang, Sima Yi's blockade will naturally not be broken, but will be countered.

The strongest point, if it can be broken, it will often become the most deadly place, Sima Yi has taken the life gate of the Han army, and wants Liu Yi to crack it, he can't think of how to break it now, but since it can't be broken, then put it to death and live again, and go directly to fight the life gate of the Wei army, then it is naturally Cao Xiu, but this kind of thing, only Guan Yu can do it, Liu Yi naturally can't do it, so he gives Guan Yu the right to choose, if Guan Yu is not willing to take risks, then think of other ways.

"Sima Yi is indeed here." Guan Yu said in a deep voice.

"In this way, the child can guard this place for his father, and Zhou Xuan with Sima Yi, and his father can lead people to return to Yique Pass as soon as possible, waiting for the opportunity to break the enemy!" Guan Ping hurriedly said.

"Without further ado, for my father, I will leave to return to Yique Pass, Zhou Cang!" Guan Yu nodded and looked at Zhou Cangdao.

"The last general!" Zhou Cang hurriedly took a step forward.

"You stay, assist Tan Zhi and that Sima Yi Zhou Xuan, Sima Yi has seized a lot of weapons from our army, Tan Zhi beware!" At the end, Guan Yu looked at Guan Ping and instructed, the weapon made by Liu Yi is not a joke, and if the stray arrow is shot, it may hang directly.

"Father, don't worry!" Guan Ping's face was stunned, and he hurriedly said.

In order not to make Sima Yi suspicious, Guan Yu changed the clothes and armor of ordinary soldiers and left the military camp single-handedly to go to Yique Pass.

Guan Ping continued to follow Guan Yu's ideas, ordered craftsmen to make siege equipment overnight, and at the same time changed into Guan Yu's outfit and constantly haunted the army, inspecting the barracks, appeasing the army's heart, but also not to make Sima Yi suspicious, after all, Sima Yi set up a high platform in the camp, and Sima Yi could see the situation here.

Of course, it can't be too often, too much, Liu Yi has studied with Guan Ping on how to deceive people to make people believe the truth, from psychology to behavioral performance, Guan Ping looks honest like this, in fact, it is the easiest to deceive people, and Guan Ping is indeed talented in this area, and the entire army has not been abnormal because of Guan Yu's departure, whether it is from the perspective of outsiders or his own people, there is basically no difference from Guan Yu in the military camp.

"What is Han Jun doing at the moment?" In the camp of the Wei army, Sima Yi summoned the soldiers who were in charge of investigating Guan Yu's movements and asked.

"The other side began to build catapults in the army." The soldier bowed.

Sima Yi nodded when he heard this, this was in his calculations, but Guan Yu was unwilling to spend his life to attack the camp, but he also missed the last chance, at this time, how could there be a woman's kindness?

waved off the soldiers, Sima Yi shook his head, if Guan Yu attacked at any cost, he might be worried, after all, the current combat effectiveness of the Han army, for the Wei army, is really hard, and the final victory is unpredictable, but at the moment, Guan Yu chose to break down with him step by step, but he also missed the last opportunity, just hold for a few days, and wait for the other party's food to run out, Guan Yu's army will naturally be self-defeating.

Although Sima Yi is good at calculation, it is impossible to really predict everything, although he has been sending people to monitor the movements of Guan Yu's camp on the high platform, but the change of the opponent's main general, Sima Yi has not been able to detect it in time, and the things on the battlefield are one step behind, and the ending is two completely different results.
