"It is impossible to rely on a letter alone, but what if you add the plague?"

"Ma Teng and Guo Yan and others, the reason why they besieged Tongguan but did not attack, in addition to the majestic and sinister Tongguan, the more important thing is to sit and wait for our army to break out of the plague, so as to win without a fight, but if this plague appears, a plague is rampant in Tongguan, facing the opportunity to defeat our army, plus our army seems to have no power to resist, if you add the letter written by the king to Ma Teng at this time, it is enough to make Guo Yan think of the place we want him to think!"

There is no doubt that Sima Yi's counter-plot lies in the hearts of the people, if Ma Teng and Guo Yan trust each other very much, without the slightest trace of filth, then Sima Yi's work is completely useless.

But if it is the other way around, Sima Yi's strategy is to completely destroy the meager and weak trust between Ma Teng and Guo Yan, and without trust, it is self-evident what the former enemies will do.

After thinking carefully about Sima Yi's strategy, Cao Cao couldn't help but secretly say in his heart, Sima Yi is vicious enough, or insidious enough, such a strategy, even if it is himself, if he is not cautious, as long as there is a trace of luck, it is easy to fall into Sima Yi's trap, and cautious, obviously this character is unlikely to appear in Ma Teng and others who have been fighting for many years.

"Okay, just follow Zhongda's strategy, Lone immediately sent a letter to Ma Teng, as for the corpse, so let's do it, Zilong, you will cremate the corpses one by one slowly, remember, you must do it secretly, and you can't let Ma Teng and others find out the flaws!"

The defeat of Ma Teng seemed to be just around the corner, and Zhao Yun and the others also raised their spirits, and they retreated one after another to do their own things, while Cao Cao began to write a letter to Ma Teng on top of the case.

There is a sample of the letter written by Emperor Wu of Wei to implement this strategy on the basis of history, Cao Cao wrote it very well, it seems to be ordinary at first glance, but if you look closely, you can find that there is a secret in it, which can be said to be virtual and real, and it is very easy to arouse suspicion.

Sima Yi, who saw Cao Cao's envelope, sighed in his heart, and was more sure of the success of his strategy, so he sealed this envelope, handed it over to a soldier, and instructed him to give it to Ma Teng at night.

The time soon came to night, and the Wei soldiers, who were ordered to deliver the letter, not only handed the letter to Ma Teng, but also inadvertently let the people belonging to Guo Yan see it, and that night, Guo Yan came to Ma Teng's military tent.

"General Ma, I heard that Cao Cao sent someone to send a letter to the general, I wonder if the general can show it to the general?"

As Sima Yi said, the union of Ma Teng and Guo Yan is entirely due to the powerful external factor of the Wei army, and it can be said that there is no mutual trust, which can be seen from the fact that Guo Yan came to Ma Teng's military formation almost a little slowly.

In the face of Guo Yan's request, Ma Teng can be described as a dilemma, show him, on the letter, although most of them are nostalgic words for the past, some of the remaining places have been blurred by ink, originally there was nothing, but on this battlefield, plus those nostalgic words for the past, don't say it is Guo Yan, even if he sees it himself, he will doubt it.

But don't show it to Guo Yan, it seems that Ma Teng has a weak heart and some unspeakable secrets, after being embarrassed, Ma Teng can only hope that Guo Yan still has some overall view and some trust in himself, but under this, Ma Teng is still dissatisfied with Guo Yan.

After all, Guo Yan came to his military tent so quickly, Ma Teng had only one thought, that is, Guo Yan had been monitoring himself, otherwise, how could he have received the news so quickly and came to his military tent, thinking that Guo Yan had been monitoring him, Ma Teng's dissatisfaction and anger in his heart were self-evident.

At the same time, he secretly hated in his heart, knowing that this was the case, Ma Teng, who should have put the Wei soldier to death just now, for the sake of the overall situation, still suppressed the dissatisfaction and anger in his heart, and handed the envelope in his hand to Guo Yan: "General Guo, please take a look, it's just an ordinary letter, and I don't know what Cao Cao is thinking, is it possible that he thinks that in this way, our army will forgive them?" ”

Guo Yan smiled at Ma Teng without the slightest emotion, and after taking the letter, when he saw those nostalgic words of the past, his face was quite normal, but when he saw those places that were completely blurred because of ink, his face became ugly, and he said in a somewhat weird manner: "General Ma, if you don't want to show it to the general, you can just say it directly, why do you want to be so pretentious?" ”

"This, why did General Guo say this, who is my Ma Teng, General Guo still doesn't understand, besides, now that the enemy is now, what the two of us need most is to be immortal to each other, and we must not mess up with ourselves, give Cao Cao a chance, General Guo, you said that what General Ben said is right."

Guo Yan's yin and yang weirdness, Ma Teng is not angry, of course it is impossible, if it were a few years ago, Ma Teng would definitely slash the past, but now, Ma Teng can only suppress the anger in his heart, be angry, and persuade Guo Yan with reason.

Not only because of his years of career as the lord, but also because Ma Teng knew very well that if Wei Jun and Guo Yan did not deal with each other and messed up, it would definitely be a great opportunity for Wei Jun.

Ma Teng's words obviously spoke to Guo Yan's heart, thinking of the more than 100,000 Wei troops in Tongguan, although Guo Yan was dissatisfied and suspicious of Ma Teng, but he still slowly pressed down, his face changed, and he smiled: "That's right, that's right, how can the general suspect General Ma, just because the general was angry in his heart, he just talked nonsense, and asked General Ma, don't mind." ”

"Nature, nature."

On the faces of the two, they talked and laughed, looking like they trusted each other and looked like good brothers, but in their actual hearts, they were wary and suspicious and angry about each other, and the meager trust between the two began to gradually break down under a small letter.

The reason why they have not completely turned against each other at this time is just because of the more than 100,000 Wei troops who still have the ability to fight in Tongguan, and it can be imagined that if the Wei army is unable to fight, what will happen between the two.

During this night, there was an undercurrent in the Xiliang army. (To be continued.) )
