The purpose of this attack on Hanoi, Cao Liang has always had a clear goal, that is, to create some trouble for the Sima clan and form a certain threat to Luoyang, but Cao Liang will not necessarily take the initiative to attack Luoyang.

After all, there is still a Yellow River between Hanoi and Luoyang, but even if there is no such moat, with Cao Liang's current strength, it is not enough to form a sufficient threat to Luoyang, after all, before Sima Yi's southern expedition, Luoyang's defense has been deployed, even if the Bingzhou army has achieved a great victory in Hanoi, but it is still quite difficult to really cross the Yellow River and capture Luoyang City.

What's more, there are still the remnants of Chen Tai's forces in Hanoi to guard Huai County, if Cao Liang does not move in Hanoi, Chen Tai will not have the courage to go out of the city to fight again, but if Cao Liang invests heavy troops to attack Luoyang, Chen Tai in Huai County will inevitably become a huge hidden danger, and the entire back road of the Bingzhou army may be copied.

If Cha Cao Liang really wants to attack Luoyang, Chen Tai of Huai County must be solved, and there is no room for negotiation at all.

Although Chen Tai was hit hard in the Battle of Wulongkou, and also lost some troops in Yewang and Wenxian, he still had some hole cards in his hand when he retreated to Huaixian, even if he poured all the troops of the state army to attack Huaixian, it would never be an easy battle.

Rather than paying the price to attack a city that is not of great strategic significance, Cao Liang might as well save his efforts, anyway, he has no intention of attacking Luoyang, as for sending troops to intimidate the Sima clan, it is completely okay.

Therefore, Cao Liang did not besiege Huaixian, but arrived on the north bank of the Yellow River with great fanfare, gathered heavy troops at the three major ferries of Xiaopingjin, Mengjin and Wushejin, and put on a posture of crossing the river at any time.

┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄

The news of Hanoi reached Luoyang, causing panic throughout Luoyang City.

Sima Zhao, who stayed in Luoyang, hurriedly discussed this matter with Gaorou Wang Sulai, mobilized troops to strengthen the guard of Luoyang City, and at the same time sent troops to reinforce Xiaopingjin, Mengjin, Wushejin and other Yellow River crossings, strictly guarding against death, and no matter what, the Bingzhou army could not easily cross the Yellow River.

Originally, Hanoi County was the first barrier in Luoyang, and Sima Yi put Chen Tai in Hanoi for the purpose of defending Luoyang, but now almost overnight, Hanoi County is easy to defend, and the entire Luoyang is immediately exposed to the attack range of the Bingzhou army, which can't help but make Sima Zhao very angry, what kind of dry food did this Chen Tai eat, Sima Yi entrusted him with a heavy responsibility, but he threw away Hanoi County so easily, what a waste!

But now Sima Zhao can't care about holding Chen Tai responsible, now Luoyang is in danger, he can only concentrate on defending it, fortunately, most of the Chinese army guarding the Beijing Division is still in Luoyang, Sima Zhao has some hole cards in his hand, but he doesn't need to be too panicked.

However, Sima Zhao still sent Luoyang's military information to the Huainan front with an urgent document of 600 miles and informed Sima Yi.

At this moment on the Huainan front, Sima Yi is leisurely and leisurely, so he is not idle.

The siege of Shouchun has reached fifteen months, and the Huainan army is now getting worse and worse, because the food is becoming more and more scarce, not only the people in the city, but even the soldiers defending the city, have begun to flee in large numbers, out of the city and surrendered to the Sima army.

Whenever a sergeant came to vote, Sima Yi would personally inquire about it, recruit these troops to the Chinese army's big tent, and inquire in detail about the situation in Shouchun City.

Although these soldiers who surrendered out of the city were the lowest soldiers, and the information they could grasp was limited, but one person could provide one piece of information, and ten people could provide ten pieces of information, and by superimposing these pieces of information, Sima Yi could get a lot of the real situation of Shouchun City.

Therefore, Sima Yi demanded that all Huainan soldiers who came to surrender should have a special person to make a record of the inquiry, and if they could provide valuable information, they would be rewarded again, so that Sima Yi could understand and grasp the dynamics in Shouchun City at any time to determine the next battle plan.

Just when Sima Yi was reading this information under the lamp, Sima Shi suddenly came in from outside the tent in a hurry, his face was solemn, and he said to Sima Yi: "Father, Luoyang urgently, Cao Liang suddenly marched from Shangdang and captured most of Hanoi, and now Chen Tai is retreating to Huai County, Cao Liang is already Chen Bing's Yellow River ferry, ready to attack Luoyang at any time!" ”

Sima Yi looked slightly stunned, put down the paperwork in his hand, took the letter handed by Sima Shi, read it carefully, his demeanor calmed down, he threw the letter on the bookcase, and said with a faint smile: "The thunder is heavy and the rain is small, Cao Liang is just a trick, not to be afraid." ”

Sima Shi's face was not easy, he said worriedly: "Father, Hanoi is lost, Luoyang is in danger, how can you say that you are not afraid?" Now we have to send troops back as soon as possible, if Luoyang loses, then we won't have lost all our efforts. ”

Sima Yi said calmly: "Shi'er, if we really send troops back to Luoyang, then we really fell for Cao Liang's plan, such a clumsy siege of Wei to save Zhao, how could my father be fooled?" ”

Sima Shi said anxiously: "It is true that Cao Liang is besieging Wei to save Zhao, but if we don't send troops back to help, once Cao Liang crosses the river, Luoyang will be in danger." ”

Although Luoyang has Sima Zhao to guard it, this is not enough to reassure Sima Shi, after all, in terms of leading the army, Sima Zhao is still too immature, it is difficult to compete with Cao Liang, and Luoyang only relies on the Yellow River natural risk, once the Yellow River natural danger is broken through by Cao Liang, then Luoyang is in danger of overturning.

However, the more anxious Sima Shi is, Sima Yi is still not moving, he smiled faintly and said: "Shi'er, don't worry, Cao Liang is just bluffing, now he is in Huaixian Chen Tai disregarded, but the troops are on the Yellow River, posing as if he wants to cross the river, it is just malicious intimidation, if he really has the heart to cross the river to attack Luoyang, how can he not solve the worries of Huaixian first?" ”

Sima Shi suddenly realized, it seems that Sima Yi has seen it more thoroughly, and he can see through Cao Liang's true intentions at a glance, and it is no wonder that Sima Yi can still maintain his composure after hearing this news that almost everyone is mad.

Originally, he was already a hole in the fire, it seems that this Jiang is still old and spicy, and he has a lot to learn, just Sima Yi's calm and calm mind, he really can't learn it.

Sima Shi admired his father's five-body throw, strategized in the strategic, and won thousands of miles away, this mind and courage will always be an example for him to learn.
