Liu Qi plotted with Wolong and Fengxiao to lead the war out of Jingzhou as much as possible, and at this time, Guanzhong was already tense.

Cao Hong lost Chang'an, retreated to Tongguan, and immediately took revenge with his whole army, and rushed to attack Banyue, wanting to break the city and capture Ma Teng's father and son.

However, Chang'an, as a former royal city, is so strong, and there are countless grain, grass and weapons in reserve, which are enough for three years, so they can only retreat in a hurry.

Seeing that Cao's army was strong, Ma Teng weighed it again and again, and decided to invite Han Sui to come to help in the war, but with his own strength, he could not stabilize the situation in Guanzhong at all.

After Han Sui sent troops, Ma Teng led his troops to take Tongguan, only by taking this place, Chang'an can be safe and sound, otherwise Cao's army will attack at any time, and it will not be a long-term solution.

The Xiliang army besieged Tongguan, Xu Huang persuaded Cao Hong not to go to war, stick to the help, and wait for two days, Sima Yi led 20,000 elite soldiers to arrive.

Cao Hong was looking forward to reinforcements, and he was holding back his anger to be ashamed, thinking that Cao Cao would not come in person, at least he would send Zhang Liao or Xiahou Yuan, but he didn't want to come to a Confucian student, what is going on?

is a mere literary peng, I'm afraid it's not as good as Zhong Xuan!

Sima Yi was tepid, and after the ceremony, he asked Cao Hong to read the military order, and asked, "I don't know what the current military situation is?" ”

Cao Hong glanced at it, threw it on the table casually, and looked at Sima Yi: "You are a professor in Xuchang, and you also know the art of war?" ”

Sima Yi hugged his fists and said: "I know a little bit about it!" ”

Cao Hong snorted slightly: "I have heard of Sima Bada's name, but you have never been in battle against the enemy, isn't it just talking on paper and misleading me for a big deal?" ”

Sima Yi is neither humble nor arrogant: "Since he was appointed by the prime minister, his subordinates should do their best, and it is a blessing to be able to share the worries of the general!" ”

Cao Hong asked: "How to deal with the current situation?" ”

Sima Yi clenched his fists and said: "Let your subordinates go to the city to observe the enemy's situation and think about countermeasures." ”

Cao Hong waved his hand: "Gongming, you take the military division forward." ”

Although he didn't trust Sima Yi, Cao Cao's general order could not be disobeyed, but he wondered in his heart, Guanzhong is such an important place, sending a Confucian who has never fought a war, could it be that there is another deep meaning?

Xu Huang took Sima Yi to the pass to inspect the enemy's situation, introduced the military situation of the two armies one by one, and asked: "Does the military division have a strategy to break the enemy?" ”

Chang'an has 100,000 Xiliang troops, and Han Sui's reinforcements are coming, and Chang'an must be recaptured as soon as possible, otherwise Guanzhong will not be protected.

Sima Yi pressed his hand on the juncture, quietly looking at the Xiliang army neatly arranged outside the pass, although the cavalry was majestic, swords and guns were like a forest, but they were not good at attacking the city, and only insulted and fought under the pass.

After a while, the Xiliang army retreated, and Sima Yi said: "The two generals are properly deployed, so they will defend the palace according to this law." ”

Xu Huang suddenly frowned, thinking that after watching it for a long time, he would just say such nonsense, so what use do you need?

When the two returned to the camp, Cao Hong raised his eyebrows when he heard this: "With the high opinion of the military division, when can we send troops?" ”

Sima Yi said: "When Han Sui's soldiers arrive in Chencang, they can break the horse." ”

Cao Hong sneered: "When Han Sui's soldiers arrive in Guanzhong, the Xiliang army will have 200,000, and the few soldiers will not be able to break the enemy, how to deal with the large number of soldiers?" ”

Sima Yi said: "When Han Sui's soldiers arrive, Ma Teng no longer has any worries, and he will go all out to take Tongguan because of his strong army, and when his soldiers are arrogant, they can break it." ”

Cao Hong had nothing to do at this time, waved his hand and said: "According to the plan of the military division, but there is no joke in the army, if its reinforcements arrive, but there is no way to break the enemy, can you afford the consequences?" ”

Sima Yi hugged his fists and said: "Since my subordinates came on the orders of the prime minister, they know that they have a heavy responsibility, how dare they play child's play?" ”

Cao Hong couldn't think of Cao Cao's intentions for a while, so he had to wait and see what happened, handed over the matter of guarding the pass to Xu Huang, and hid in the backyard to rest.

Sima Yi and Xu Huang guarded the pass together, and asked: "The general is from Hedong, and he must know something about the ferries along the river, so he has something to ask for advice below." ”

Xu Huang's heart moved, and he asked: "Does the military advisor have to cross the river from the east of the river and harass behind the enemy?" ”

Sima Yi nodded and said, "That's exactly what I mean!" ”

Xu Huang sighed: "I know that I can go straight to Weishui from Pu Hanjin, and I also intended to attack the enemy camp. However, there are 100,000 troops in Xiliang, and the cavalry comes and goes like the wind, and it is easy to be detected by the many soldiers. ”

Sima Yi only showed a smile at this time: "The general only needs to explain the terrain here, I have my own plan to destroy the enemy." ”

The two discussed the situation in Guanzhong at Guanshang, and in the following days, Sima Yi ordered 20,000 reinforcements to set off in batches from Fengling to Hedong to stand by.

A few days later, Tanma reported that Han Sui's vanguard had arrived in Chencang, and the army was coming, with nearly 100,000 cavalry, and the momentum was huge.

When Sima Yi heard the news, he immediately asked Cao Hong to discuss the matter, and took the initiative to ask him to cross the river north with Xu Huang and attack behind enemy lines from Weishui.

Xu Huang hurriedly said: "Tongguan is very important, and it is imperative for a certain assistant General Cao to guard the pass, how can he leave lightly?" Isn't it about taking the big from the small? ”

Cao Hong said dissatisfiedly: "Looking at General Xu's intentions, could it be that he can't hold Tongguan?" ”

Sima Yi hugged his fists and said: "General Cao has been used to fighting for a long time, and he only needs to guard Tongguan for ten days!" ”

Cao Hong laughed and said: "The two of you also underestimate a certain family, don't say ten days, that is, a hundred days, a certain person can keep it." ”

Xu Huang said: "After attacking and harassing the enemy, success or failure has nothing to do with the overall situation, if Tongguan is lost, it ......."

"In the words of the public, guarding Tongguan is all about your merits, which will be dispensable?"

Cao Hong's slight affection for Xu Huang disappeared again, and he squinted at him: "Then I'll go?" ”

Xu Huang hurriedly said: "The last general has no such intention......

"Well, no need to say more!" Cao Hong was impatient and ordered: "The military division has never led the troops, and the general is in need of help, I order you to be the vanguard, and act with the military division, there must be no mistakes!" ”

Xu Huang was helpless, received the general's order, and left Tongguan with Sima Yi and rushed to Fenglingdu.

On the way, Xu Huang still didn't worry about Cao Hong, and kept chattering: "You and I go to Weishui, if Tongguan is lost, isn't it because of a small loss, a dilemma?" ”

Sima Yi smiled lightly: "General Cao has followed the left and right since the day the prime minister started his army, and he knows the art of war very well, so he can keep Tong safe. ”

Xu Huang hurriedly said: "The military advisor doesn't know, General Cao is irritable, I'm worried that he has fallen for Ma Teng's plan......"

"General Xu!" Sima Yi interrupted Xu Huang and said: "It is taboo to talk about the shortcomings of others behind your back, General Cao is a confidant of the Prime Minister's family, and you need to prevent the partition wall from having ears." ”

Xu Huang was stunned for a moment, and said in a deep voice: "Xu is a major national event, he should be outspoken, where his responsibility lies, how can he be a general and avoid medical treatment?" ”

Sima Yi sighed: "The general thinks that he is upright and dedicated to the public, but he must also beware of villains!" Today's general is talking about General Cao, but behind the general, no one is talking about you? ”

"Why are you afraid of what others will say?" Xu Huang snorted slightly, glanced at Sima Yi, but lowered his head and stopped talking.

The contradiction between him and Cao Hong arose precisely because of this, and Ma Yan and others secretly provoked it, which made the generals discordant.

This young Confucian scholar is well versed in human nature and has a deep mind, could it be that this is what the prime minister likes about him?

The two crossed the Yellow River and came to Puhanjin, Han Hao had already ordered someone to prepare a raft, Sima Yi was not in a hurry to cross the river, and it was rumored that the horses were resting and waiting, and only sent scouts to drive fishing boats to inquire about the news of Guanzhong.
