Outside Lin'an City, looking at Jia Yidao, who was galloping away, feeling the hug that seemed to symbolize etiquette or gratitude when he just left, and feeling the temperature and breath that seemed to remain, Shi Zhenxiang was in a trance.

Jia Rudao left, after all, he still didn't choose to risk the world's condemnation and return to Lin'an City.

The turnaround was simple, but the chain reaction it caused was not necessarily something that his small body, which seemed stronger than before, but was actually weak, could afford.

Whether it is Qiao Xingjian, Li Mingfu and the like, or those officials who are angry every day, or those who have not found out who has attacked Jia Guifei so far, they are all very happy to see this scene.

Although he was helpless in his heart, although he really wanted to go back and have a look, Jia Rudao had to admit that Shi Zhenxiang was right.

In his previous life, he didn't enjoy the fun of being a father, and when he wanted to practice filial piety, he also wanted to raise his son but his relatives were not there. Reliving a life, happiness came too suddenly, but it was too untimely.

In addition to happiness, Jia Yidao's most important thing in his heart is self-blame. Judging from the fact that Xu Ruoxi has already had a pregnancy reaction, it is obvious that pregnancy is not a day or two, at least it is possible for more than a month or even two months. But as a husband, he didn't notice anything abnormal at all, and he couldn't explain it to reason. Therefore, although he is angry about Xu Ruoxi's concealment, it will definitely not be as much as Shi Zhenxiang or Xu Ruoxi thinks.

Thinking about what she saw when she came back a few months later, Xu Ruoxi, who was already pot-bellied, was not by her side even when she was pregnant, and even made her scared, Jia Rudao was full of guilt, and only wanted to rush to Xiangyang City as soon as possible, and then rush back as soon as possible.

Can't delay until the son is born, the first person he sees when he opens his eyes is not his own father, right?

So, since you can't turn back, you can only go back quickly. Jia Rudao naturally doesn't know the Tao at this time, the ideal is always very plump, and the reality is always so skinny.

For Shi Zhenxiang, Jia Rudao can only be grateful. No matter how many grievances there are between the two, at least Shi Zhenxiang proves that she really treats Xu Ruoxi as a sister, and even does not hesitate to face her own cold words and the gossip of others.

Favors are obviously not available now, and since they have already gone back quickly, the only thing that can be done seems to be to turn around and leave immediately, now, immediately.

Jia Rudao is not an indecisive person, so he solemnly thanked Shi Zhenxiang and asked her to take more care of Xu Ruoxi, and gave her a big courtesy hug without any other hugs, and then got on the horse and left.

It wasn't until there was no one in sight in the distance that Shi Zhenxiang turned around and ran to Lin'an City under the urging of the guards.

……

When Meng Heng received the news of the movement of the Mongol army in Caizhou City, he was outside the city to inspect the bunker built by the Ningwu army outside the city of Xiangyang to defend against the Mongol cavalry and limit the mobility of the Mongol cavalry. At this time, the 50,000 Mongolian cavalry, who were the vanguard of Xiangyang in the south, had already arrived at Tangzhou City, which was only a hundred miles away from Xiangyang City.

This was the time when the Detective Division's dark line had only been able to grab after three horses had been killed. The Mongol cavalry was able to sweep across Eurasia, which showed its unrivaled mobility.

Since the capture of Xiangyang City, although Caizhou City's mouth temperature has always been unmoving, Meng Hui has never relaxed his vigilance. In addition to repairing the broken city walls to appease the people, the first thing Meng Heng did was to drive the army to start building bunkers around Xiangyang City.

This suggestion to build a low bunker to defend against the Mongol cavalry was still what Jia Rudao said when he first wrote to him. Although this in itself was originally used by Meng Heng to deal with the Mongolian cavalry in history, it is now a clever move by Jia Yidao.

Relying on the three rivers of Fu, Zhang, and Han, forts and passes were built to prevent the Mongolian cavalry from driving straight to the city of Xiangyang, which was the strategy of Meng Heng copied by Jia Yidao, of course, along with Jia Yidao's letter, there was also a complete river line map in Meng Hui's hands, and in various important positions, Jia Yidao made marks, and what Meng Heng is doing now is to rely on Jia Yidao's defense map to make targeted arrangements according to the map.

In addition to building fortresses and passes, Meng Hui also adopted Jia Yidao, relying on Xiangyang, strictly guarding against Jingxiang, and backing Jiangling to lay out the entire Jinghu Theater, focusing on building a complete defense system that can radiate Huaixi, Huaidong and even the Sichuan Theater.

In this defense system, the most important thing is that the first thing to do in the Jinghu Theater is to be self-sufficient, and in addition to ensuring that Xiangyang City is not lost, the remaining two most important parts are the supply of troops and food.

The current situation of the Great Song Dynasty is obviously not too much spare power to feed back to Xiangyang City, if all the hopes are pinned on Lin'an City, the probability of delaying the fighter plane is 100%, this is not only because the Great Song Dynasty is too weak, but more importantly, because of the biggest limitation of this era, that is, poor information transmission.

Fighting a prepared battle is the favorite thing of every commander-in-chief, but it is obvious that things in the world cannot be so satisfactory. Most wars and even battles actually happen suddenly, especially when one side has an absolute advantage and the other side is mostly on the defensive, it is obviously impossible for the other side to greet you in advance before each attack and say that I am going to attack, are you ready? Not ready, how about I wait? Such a thing seems to be able to occur only in the fantasy of the Datong society.

But if it's really a Datong society, how can there be a war?

Therefore, what the commander of the army can do is to be as prepared as possible, to be ready to deal with any sudden situation at any time, to be ready to fight a big battle at any time, and to be able to win a battle.

Although Jia Yidao's letter did not say it explicitly, both Jia Yidao and Meng Heng knew in their hearts that if the tacit things between the two were really done, relying on the Jinghu Theater to be self-sufficient, then Meng Hui would completely break away from the clamps of Lin'an City and become the biggest warlord in the Great Song Dynasty.

There is an important thing in the middle, that is, how will the imperial court choose?

Of course, Meng Hui didn't know, but Jia Yidao knew very well that the current Great Song Dynasty had no other choice at all. I could only agree to Meng Heng's suggestion to recruit troops to Tuntian, and even had to provide him with some necessary help.

Because once Xiangyang City is lost, the complete defense line of Jinghu, Huaixi, Huaidong, and Sichuan Theaters will no longer be complete, which is equivalent to the Mongols nailing a deadly nail between the hearts and cores of the Great Song Dynasty, and they can rely on this nail at any time to result in the life of the Great Song Dynasty.

In this matter, Meng Hui and Shi Songzhi only saw the importance of Jingxiang Land to the Great Song Dynasty's defense against the Mongols, but they definitely did not expect it to be so far-reaching, and even said that Jingxiang Land was so important. However, as a latecomer familiar with history, he knew very well that the fall of the Great Song Dynasty began with the collapse of Jingxiang. In the original history, Xiangyang City was lost again, and then the Great Song Dynasty was completely wiped out in just a few years.

The importance of Jingxiang Land in the minds of the Great Song Dynasty is not really seen by many people. However, this is Meng Hui's chance, isn't it? If you really see it so clearly, I'm afraid that Meng Heng's ass will be replaced by someone before it is hot, right?

In Jia Yidao's plan, Jingxiang and other places and even the Jinghu Theater are actually already in his pocket, and he will naturally not be stingy and guide Meng Heng to avoid detours. Of course, this is not enough for outsiders.

Looking at the news from the Detective Division, Meng Heng's mood couldn't help but sink.

The various defensive measures of Xiangyang City have just begun, and the city has been repaired, but the fortress and pass are far from being completed, and it can even be said that it has just begun, and the completed are just a few important pass fortresses on the tributaries of the three rivers.

If the Mongols are entangled in this Xiangyang City for a year, well, not for a year, it only takes two months to three months, I am afraid that the food in Xiangyang City will be exhausted, and with the Mongol cavalry, the food on the land route will obviously not be able to be transported in, and the only thing that can be considered is the waterway. However, if the food of the imperial court is too late to replenish, once there is a shortage of food, Xiangyang City is afraid that it will be self-defeating.

Hundreds of thousands of Mongolian troops poured into the nest under the personal supervision of King Zong Wen Buhua, and there were Shi Tianze and Zhang Rou, two old friends who Meng Heng had dealt with before, but now they knew each other very well, how could Meng Heng not be surprised.

However, after all, Meng Hui was a famous general in the battle formation, so he immediately packed up his mood, and while ordering people to rush the generals to come to discuss the matter, he urgently reported the news of the attack of the army to the imperial court.

This pre-war meeting lasted for half a day, and when the generals of the Ningwu Army and the Jinghu Army came out of Meng Heng's tent, their faces were not very good-looking.

Soon, all the Song troops in Jingxiang, including Xinyang and other places, began to move. The Xinyang Army, Zaoyang Army, and Suizhou Army stationed in Xinyang all abandoned their garrisons and returned to Xiangyang City, and took away everything that could be taken away in the city, and those that could not be taken away were burned on the spot.

The unfinished fortresses were destroyed on the spot, leaving the Mongols with absolutely no material to use, and the armies of all stripes began to gather the people scattered around Jingxiang and take them all to Xiangyang City to escape the impending war, so that these innocent people would not be slaughtered by the Mongols. In fact, if Meng Hui only spread the news that the Mongols were about to attack the army, and he didn't need to send troops to collect it, these people would themselves take refuge in Xiangyang City. Meng Hui was only worried about causing panic and chaos, so he hid the news for the time being.

After thinking about several pass fortresses that had just been built, Meng Heng also ordered them to be destroyed and burned, and then all his troops were concentrated in the two cities of Xiangyang and Jingzhou.

With more than 1,000 warships of 50,000 sailors, the two cities could be directly connected by waterway, and Meng Heng was not worried about being cut off by the Mongol cavalry. After all, compared with the land army, in terms of the water army, the Mongols can only be regarded as toddlers in front of the Great Song Dynasty sailors.

Meng Heng's idea was very simple, give up all unnecessary defensive places, concentrate a large army to hold the two cities of Jingxiang, and must hold it, and consume time with the Mongols.

Along the Yangtze River, the entire Jinghu Theater instantly entered the trend of wind and rain because of the warmth of hundreds of thousands of troops.

On July 24 in the summer of the second year of Jiaxi, the first Song-Mongolian battle after the Battle of Xiangyang suddenly broke out without warning when both sides were not expected and unprepared.
