When Yu Yunwen and the others saw him enter, they immediately retreated from both sides, allowing Zhao Huan to stand in front of the sand table.

The production of this sand table actually began in the Spring and Autumn Period in ancient China, but the proportion distortion effect was very small, and it was slowly lost. Of course, Zhao Huan knew that it was better to replace the military maps of the ancients with sand tables that had no proportions and latitudes at all, but he could only put forward ideas and let people compile more accurate maps, and then pass on his simple geometric drawing knowledge to others, so that he could barely make this huge sand table with rough effects.

If you want to have a military sand table with extremely high accuracy in later generations, you have to have higher and more developed basic science, which Zhao Huan cannot change with his own strength.

The school he ordered Qin Hui to build naturally had Western basic science books that had been purchased by Arab traders with a lot of money in recent years, and it was necessary to wait for the translation to be completed, and then screen and use them, and combine them with Chinese classics for students to study, and it would take more than ten or twenty years before they could see the initial results.

However, Zhao Cabinet was already very satisfied with the achievements in front of him.

The Guanzhong Plain, the Taihang High Valley in Hedong, the Qinling Mountains, Jingxiang and the Liangzhun Plain, the Yangtze River with a strip of water, and the entire theater of war are all expressed by this sand table, and the commanders of each theater also have more detailed local sand tables to use to command and fight.

At this time, in front of Zhao Huan's eyes, it was a sand table made in a certain proportion based on the map of his memory and actual exchange, and the small red and blue flags symbolized the deployment of troops in the Song and Jin countries.

As in the same situation as last year, most of the main forces of the Song army were still stationed along the east of the Guanshan River and Tongguan, while in Jingxiang in Liangzhun, only Han Shizhong, Yue Fei, Yang Yizhong, Zheyanzhi and other forbidden troops were stationed. In order to ensure its status, this puppet regime has desperately recruited troops in the past two years, coupled with the vigorous support of the Jin State, and given more war horses, so that it has established a force of more than 500,000 people, and the war horses have surpassed the soldiers of the Song army. Although few people are willing to fight for the puppet Qi regime with their hearts, they are basically bound to lose every battle. However, the blue banner facing Jingxiang Liangzhun is densely planted, and judging from the number of garrisons alone, the Song army in Jingxiang Liangzhun can ensure that the current defensive position is already a good result.

In fact, on the contrary, the main force of the Jurchen cavalry was not here, and after the autumn and winter, because there was no major war, most of the Jurchen cavalry withdrew to the north or returned to Shangjing. Or Tunzha Youyan River. Shape the victory, and put yourself in the safety of the rear, and be able to control the development of the situation at any time. According to the actions of the Song army, mobilize troops and horses for action. After going to Jingkang for five years, the Jin soldiers realized that they might not be able to win on the frontal battlefield, and according to the form of Xindi, taking advantage of the characteristics of the main force of the Jin soldiers being all cavalry and acting quickly, they adopted the most correct military deployment, which indeed made it difficult for the Song army, which was basically composed of infantry, to take advantage of the numerical advantage, or to concentrate on encircling and attacking a certain Jin soldier or puppet army.

It can be said that Jin Bing's change of tactics. It is also a major reason why Zhao Huan has been on the defensive in Jingkang for more than six and a half years. The Central Plains and Hebei are all plains and smooth roads, and the road construction is much stronger than most places in the country, and the Song army is composed of infantry, and the movement is relatively slow.

The elephant Jin soldiers failed in their raid on Chang'an, and they were trapped in Taiyuan and lost a lot of elite good deeds. There is no way to repeat it.

In fact, every time Zhao Huan thought about Chang'an afterwards, he also felt that it was too lucky, if he was asked to re-elect, he might not have the courage to dare to hold on again in this small city with no elite soldiers and no city defense protection.

According to this situation of Jin Bing's deployment, how to break the confrontation between the main forces of the two countries, break the strategic deadlock, and turn the strategic superiority of the Song military and land into victory has been put on the topic of study by the Privy Council in the second half of the sixth year of Jingkang.

Abundant intelligence, professional analysis, and the assumptions of countless staff officers, naturally, Zhao Huan, who is familiar with the changes in history, finally drew up a professional battle plan drawn up by a staff officer in the real sense of the word in China's history according to the changes in the actual situation.

By the end of the year, most of the strategic materials had been equipped in place, which was basically the same as the war plan of the Song army in the history of Shaoxing in Zhao Huan's memory, but the details were greatly modified.

The Song army still attacked with Yue Fei as the main force, and the 100,000 people of Yue Fei's department broke through in advance and penetrated directly into Wanluo, while Han Shizhong, Zhe Yanzhen, and Yang Yizhong followed closely behind, directly penetrated into Jingdong and Shandong, and echoed Yue Fei from afar.

In this way, the main force of the Song army, with about 200,000 people, will sweep across the Central Plains and Shandong, completely destroy the deployment of the pseudo-Qi and Jin soldiers in these two places, and attract the main force of the Jin soldiers to the hinterland of the Central Plains to fight the Song army.

When most of the Jin soldiers were attracted to the Central Plains battlefield, the Song army stationed in Hedong went straight to Hebei, seized various strategic cities, cut off the enemy's rear route, and at the same time the Zhaguan garrison attacked, cooperating with the Song army that entered the Central Plains in advance, and strangled and eliminated the main force of the Jin soldiers who entered the Central Plains.

After the Jin soldiers fell into the trap, they faced a large encirclement spread by the elite of the Song army of nearly 600,000 people, and behind the main Song army, there were hundreds of thousands of Xiang troops, as well as millions of people to prepare for this big battle, with the current field combat ability of the Song army, plus the many cities in the Central Plains, there are many geographical advantages that can be used, the enemy's main field cavalry has been less than 100,000 after several blows, once it falls into the encirclement of the Song army, it is difficult to retreat, and when the enemy army wakes up and cannot be defeated, it begins to retreat, Behind him, there is a Song army to cut off his back road, and there must be bloody battles along the way, and when he escapes beyond the Great Wall, he is afraid that there will be only a few people left.

Yu Yunwen and the others fiddled with the flags on the sand table, analyzed them in detail, and combined with the newly obtained financial and logistical information, they were already extremely detailed, and there were no omissions.

Zhao Huan focused on what was in front of him and watched carefully, but he always felt that he couldn't concentrate.

In front of him, there seemed to be countless big men with red and black faces who looked like peasants, the iron clothes on their bodies crackled, the spears in their hands flashed with cold light, screaming and waving, and charging into battle.

And behind them, there were frightened Jurchen cavalrymen, the original arrogance and self-confidence were gone, supporting corpses all the way to the field, broken flags and dead horses winding behind them, and the aristocratic generals who fled first did not dare to look back.

Zhao Huan shook his head suddenly, putting this overconfident emotion out of his mind, because he was too nervous, his voice was a little hoarse, and he said with a tired face: "You have worked too hard, these days have come to the last moment, you have not slept for a few nights, and you will go down from me here in a while, and then go to rest." ”

Yu Yunwen smiled slightly, but did not promise. He was appreciated and promoted by Zhao Huan, and in just a few years, he has become the deputy privy envoy, so to speak, it can be said that Zhao Pu, the old friend of Emperor Taizu, did not improve so quickly. Between the government and the opposition, he is also very concerned about his promotion, but he is also a scholar and a member of the scholar, and he is dignified, not arrogant because of his young career, and treats people like an old Confucian who has been an official for decades. In this way, Neixiu is naturally innate, and it is also the reason why his knowledge and insights are far beyond ordinary people, coupled with the support of Yao Pingzhong and other old friends, so he reluctantly did his official position, but Zhao Huan's kindness of appreciation and promotion and reuse is in the hearts of scholars, except for the four words "do your best", there is no other way to repay it. No matter how talented Yu Yunwen is, he can't break the influence of the times, and he can only repay Zhao Huan with desperate effectiveness.

Seeing him react like this, Zhao Huan was not surprised, if it was usual, at this time, there was no reason for some palpitations, and he couldn't help but increase his tone and ordered: "I look at you with my heart, why will I deal with an accident when I am tired?" ”

"Yes, the minister obeys the order, otherwise, the minister will not die of exhaustion, and he will also be beaten to death by His Majesty."

Yu Yunwen has always paid attention to the calculation of last resorts, but once the decision is made, it is very rarely hindered. Zhao Huan was a little nervous, but he also noticed it, so he deliberately answered Zhao Huan in a very relaxed tone.

He interrupted again and again, and Zhao Huan's mood was slightly relaxed.

But it is no wonder that he is like this, such a strategic mobilization, the Song army has almost no reserves, and the lessons of history tell him that no matter how good the plan is, there will be unpredictable accidents, and any unexpected event that should not occur may disrupt the entire Song army's war plan, making this great war a failure.

And once the campaign fails, the best result is that the Song army retreats to the defensive line and returns to the pre-war state, and within two years, it will not be able to launch a campaign of this scale again. If the Song army is defeated and can't even maintain the current state, then Zhao Huan will pay for his hard work for several years.

Thinking of this, he sighed, and after being silent for a long time, he said to Yu Yunwen: "I see that this plan has been perfected, and there is no gap. ”

Seeing that all the privy counselors in the hall were relieved, Zhao Huan said again: "However, we still need to study carefully and find omissions." Qing and others need to know that this is not a gain or loss of one city or one place, but a matter of the survival of the society. ”

What he said, everyone in front of him is a hero, how do you not know, but the emperor put forward it so solemnly, but it is the first time, led by Yu Yunwen at the moment, everyone lowered their heads, and replied loudly: "Ministers, you must live up to Your Majesty's trust!" ”

"Okay, I will rest for a while, and then according to the information of flying pigeons in various places, I will analyze it in detail, list it, and study it again. Yu Yunwen, you can pass on to Fei Lun at any time, and I order them not to hide all the news, so that you know everything. ”

Zhao Huan arranged this matter properly, knowing that in a few days, the details and orders of this big battle would be transmitted to the officers at the command level, and the Song army, a huge war machine, was about to start its official operation.

He took a long breath, looked up at the sky, and saw that the sky was blue and far away, and he was originally a person who did not believe in gods and Buddhas, but he couldn't help but clasp his palms together and secretly said: "May God bless China!" ”
