Bai Yijie put down the scroll of pictures, glanced at Zheng Yunming who was thinking in the seat from the corner of his eyes, and continued:

"It would be too negative to say that as long as you accumulate national strength and wait for the opportunity. Fortunately, the Mongolians occupied the Central Plains shortly after they occupied the Central Plains and did not intend to use the rules and regulations of the Han area. This may be the decline of the Taoist dynasty in the eyes of the general manager, but for the use of the best time."

"The Mongols originated from the northern desert and were crude and unwilling. They governed the Central Plains entirely by the local powerful people, sent talented people to infiltrate, detect intelligence, convey information, distract the relationship between the Mongols and the Han people, and even lurked to the Khans, misleading the Mongols' economic and political strategies, and induced them to my advantage..."

"This is a big risk." Although Zheng Yunming has not had much practical experience, since he moved south, the country has always used the news of the north-south connection as the key to determining the country's destiny. He was influenced by his knowledge and naturally knew the risks and difficulties of underground work.

"It is extremely risky to use this weak country to resist millions of ferocious beasts in the north." Bai Yijie shook his fan and said calmly: "If it weren't for a wise and brave man, no one would have come to this muddy water."

Zheng Yunming looked at his confident appearance, perhaps in his heart, he had already made a comprehensive plan for how to arrange the northern spy network.

Yang Xu suddenly spoke, "It is not enough to rely on spies to convey information. The Mongolian secrets system is very perfect, and the army's mobility is unparalleled. If you don't prepare in time, just relying on news from the north will not stop the enemy's attack."

Bai Yijie turned around and said to Yang Xuan: "It's not wrong at all, so the country should place a commander in each direction of Lianghuai, Jinghu and Guangxi, send troops to build cities, accumulate food and grass, and be ready to deal with the enemy's attacks at any time."

Yang Xun frowned slightly and asked, "Why should we set up defenses in Guangxi?"

"Guangxi needs to be set up defenses because Sichuan is difficult to defend." Bai Yijie said slowly: "The news reported by the travelers who came back from Shukou that since the fourth Mongolian prince Tolei led his army to ravage the three passes, even the most elite cavalry units of Shukou, Yi and You Yi were dispersed. They even pretended to be their identity and pretended to be Mongolians to plunder the people. The remaining little defensive forces in Shukou are at most 20,000, and the enemy often invades hundreds of thousands of times. Once the enemy goes deep into the Sichuan Tangao, the cavalry will go around and go, and it will be even more irresistible."

"So Sichuan will lose. The problem with losing Sichuan is that the enemy can implement their usual muddy strategy through Sichuan."

Wang Deng made a fist with his left hand and hit his right foot: "What do you mean by sir?"

"It's Jing Song, it's clear at a glance. Yes, after the enemy penetrates Sichuan's defense, the horse will turn to the Dali Kingdom." Bai Yijie said: "Dali has been in the southwest of 300 years. Although there are many foreign soldiers, they no longer know that the war is sharp. The sudden invasion of the northern iron cavalry will inevitably lead to panic and unable to resist. Once Dali falls, the enemy can drive straight from Guangxi and go deep into the empty rear of Jinghu."

"It's not that easy." Zheng Yunming said: "The north of Guangnan West Road and the south of Jinghu South Road are filled with banished states enfeoffed by the imperial court. The natives are strong and powerful. Even if the Tartars really have 100,000 troops, it will be difficult to pass easily."

In his later memories, he only remembers that the Mongolians repeatedly invaded Guangxi in vain, but he did not know that the Mongolian army had successfully turned north of Guangxi several times. It was just that it failed to successfully go around the back of Jinghu and the two routes.

Bai Yijie suddenly turned to Zheng Yunming: "This is not an easy or difficult problem. It is a matter of the determination of the commander. The Jin people could not even defend Henan with 200,000 elite troops. The Mongols really had to make up their minds to start the mediation. Can the Jingnan prison state stop them?"

He continued: "Now the country has only hundreds of regular soldiers stationed in each of the three states on the Guangxi border, and the strongest force is only 2,500 soldiers directly under Jingjiang Prefecture. It is difficult for the army to protect the territory and the people, and it is powerless to face the Mongolian army."

"So within the latest ten years, at least 30,000 people must be prepared in the direction of Guangnan West Road. These 30,000 elite soldiers must be good at mountain warfare, guarding all the important roads from Dali to Guangxi, and responding to emergencies in Dali at any time."

"This is a perfect solution." Zheng Yunming said: "It's a pity that the country's troops are insufficient, so it's a blessing to be able to defend the Beijing, Lake and Huaihe River. It's not a matter of preparing 30,000 elite troops in Guangxi."

"This matter is for Xu Tuzhi." Bai Yijie said: "But there is one thing that needs to be done soon, otherwise the country will be at risk of being destroyed immediately."

Zheng Yunming lowered his head and thought for a while, and asked, "What sir said is to rectify the navy?"

"It turns out that the country's border areas are put in our hearts." Bai Yijie praised and continued: "There is no doubt that the navy in the south is very powerful now. The rafts and veins made by the Mongols are not our warship opponents. But the navy still has two problems."

"First, the navy troops in various places are set up by local generals and the ships and sailors are prepared by themselves. The quality and combat power of the navy are uneven. For example, the current Meng Dutong of Huangzhou, Li Dutong of Zhenjiang, and Jiang Dutong of Hanyang have good water troops. However, the navy established by some small prefectures and counties often only use civilian ships instead of warships, and soldiers are recruited randomly without training."

"Secondly, our naval army often acts on its own and lacks coordination and cooperation with the land armies. The Hu people can be our example in this regard. I heard that this time, whenever there is a water battle, the Hu people will inevitably send cavalry to the shore to shoot arrows to assist the navy in combat. It often leads to our army being defeated by attacking from three sides. The cooperation between the various armies and facing the enemy on multiple sides is the foundation of military strategy. If you don't understand this, even if you have a powerful naval army, it will be useless."

"I have heard a lot about the disadvantages of the navy in Lin'an." Zheng Yunming refers to the mutiny of the Zhejiang navy in the Jiangnan area before he set off for Xiangyang. "Not to mention the small fleets of prefectures and counties, even the navy directly under the Imperial Front Office stationed in Jingkou was disbanded. Once he was dissatisfied, he would take the chief to mutiny. Many of them were children of nobles in Lin'an City. Even the imperial guards were like this, and the quality of the national navy was evident."

"I have been thinking about rectifying myself, but I haven't waited for the right time."

Bai Yijie said: "Since the general wants to live in Xiangfan for a long time, it is impossible for the court to not give the general the power to command the naval army. I expect that the naval army will be transferred to your command later, or you will allow you to build a fleet by yourself. This problem is not serious, because it is the strength of the southern people. Another defect in military preparation is fatal to the Song Dynasty."

The muscles in the corner of Zheng Yunming's eyes twitched slightly. The entire Song Dynasty knew about this other defect, and the whole world knew about it, but how many generals and ministers, who had the great talents and talented efforts to improve this defect were almost no results.

"There is no way to do this defect," Zheng Yunming's tone was low and dark and heavy: "The only thing the country can rely on is the trade between Longnan and Tubo. Others, such as Sichuan horses, southern horses, and Guang horses, can only be used for transportation and transportation of food and supplies, and cannot be used for driving on the battlefield. Now that the Mongolians have invaded Shukou in large numbers, our army has retreated step by step. They have long lost their connection with the Qin and Long Tubo tribes. And the news recently received that the main 18 Western British tribes in Longnan have surrendered to Mongolia. Since then, the source of Qin horses has been completely cut off."

"In the future, our source of war horses will only wither one day or another. I am worried that in less than ten years, the number of war horses that can be used in the country may be less than one-tenth of today's number."

"That's right, so from today on, we must prepare for the future and be anxious about water and fire." Bai Yijie asked, "Don't you know that the general has seen the Sichuan geographical map?"

Of course, I have seen the Sichuan geographical map in my previous life. Zheng Yunming considered the meaning of Bai Yijie's question: "I have seen that the fourth route of Sichuan and Shaanxi are composed of Chengdu Fu Road, Kuizhou Road, Lizhou Road and Tongchuan Fu Road. Among them, Tongchuan Prefecture governs the Hanzhong area in Longnan. The other three routes are all in the Sichuan Basin. The mountains on the edge of the basin are steep and the natural danger is difficult to overcome. However, once they are broken through, there will be a smooth road on the Chengdu Plain, almost without blocking the terrain of the enemy's cavalry."

"What else is there outside these four routes?" Bai Yijie suddenly asked inexplicably.

"Besides these four routes, there are only the Yi natives in the southwest, as well as the Daxue Mountains and Songpan places to the west..."

Bai Yijie smiled meaningfully.

Zheng Yunming was stunned and then shook his head hurriedly: "It's the place where Fan Rong lives, and few Han people go there. Except for some Dangxiang people who fled from the former place of Xixia to the Minjiang River Canyon, there is the world of Qingqiang and Tubo."

The so-called Qingqiang and Tubo in his mouth refers to the Tubo tribes living in western Sichuan. Because these tribes were influenced by the Qiang people, they were different from the Tubo tribes in Hehuang and Qinghai in terms of customs. Therefore, the Song people called it Qingqiang and Tubo and distinguished it.

Zheng Yunming knew that contacting Qing Qiang was not something that could be done with casual talk, and under the current situation, this was almost impossible to complete.

"If it is true that the merchants in the Han area have been trading with Qingqiang and Tubo, it is true, but this does not mean that someone is willing to take a risk and go to the sparsely populated Fanrong area for a long-term activity. What's more, the customs of the Han and Borussia are very different, and the Tubo people regard killing as a sign of courage. If you send someone who doesn't understand the local customs, you will have a high possibility of losing your life."
