"Second, on the issue of military morale. As far as I have observed for so many days, four words - military heart is available. As the people of Datang, they know that in order to maintain such a life, everyone in Datang must pay, and now His Majesty has called, and they will step forward without hesitation. This attitude is in stark contrast to the scene of the former Sui when they heard that they were going to Liaodong, and everyone was willing to make themselves disabled rather than go, and there have been such obvious changes in a few decades, which shows that Your Majesty is indeed a wise lord, and the Mandate of Heaven is also in my Tang Dynasty. ”

After saying this, Li Dongsheng felt a burst of nausea, and he couldn't imagine that he, a real son of destiny, would say such a disgusting sycophant.

Li Shimin listened to Longyan Dayue, and he had never heard of Li Dongsheng patting sycophants, so his words were from the bottom of his heart. And this sycophant is reasonable, reasonable, and reasonable, it is really well-documented, logically rigorous, and very comfortable.

Wang De secretly gave Li Dongsheng a thumbs up, unexpectedly that this awe-inspiring guy also joined the camp of the group of pat horses, and made extraordinary moves, which made him a lot of pressure as the manager.

Li Shimin's gaze shifted to the map on the table, the map has been more detailed than other maps of this era according to the method of Li Dongsheng's map in Changlefang in the early stage, whether it is cities, mountains, rivers, valleys, etc., there are clear signs, just from this point of view, we know that Li Shimin has indeed put a lot of effort into Goguryeo, and I don't know how many spies are active.

Looking at the Goguryeo cities one after another on the map, Li Dongsheng saw a black dot that was still far away from those cities, which was estimated to be the location of the Tang Dynasty army now.

Li Shimin looked at it for a long time and measured the distance with his hands, he sighed and said: "The mountains are high and the road is long, and the cold wind is steep, the army is too hard, it is estimated that it will not be able to reach Goguryeo until next spring, if only there was a way to transport the army to Goguryeo quickly!" ”

Li Dongsheng said with a straight face: "Weichen really has such a way, that is, to use sea ships to transport the army over. ”

"Is there so much of a ship? The current ship can only use a few hundred people, didn't Cheng Chumo volunteer to sign up and lead the navy army to harass Goguryeo? ”

"Your Majesty, that's our Tang Army, it's not as good as the Sui Army." Li Dongsheng said truthfully: "If there are hundreds of such ships, it is not possible to transport tens of thousands of people at one time. Moreover, if they are scattered and landed, Goguryeo will definitely be difficult to take care of, and when the time comes, they will be exhausted from running for their lives. ”

Li Shimin looked at the map in front of him, lost his mind for a moment and said, "Does it really work?" ”

Li Dongsheng knew that this was a rare moment to instill the big navy in Li Shimin: "Your Majesty, you can imagine that if we have a strong naval army, then Goguryeo will be the turtle in the urn, on land we will block the border, and at sea we will harass with the naval army, if we win, we will fight, if we can't win, we will leave on a sea ship, change places, such a battle Goguryeo They will be dragged to death by us no matter how strong they are!" ”

"When Wei Gong attacked the Turks, he used a cavalry to imitate Huo Qubing in the Han Dynasty to fight alone, smashed the Yellow Dragon, and annihilated the Eastern Turks in one fell swoop, this time I still want to do this, is there any effect?"

Li Dongsheng immediately interrupted him and said, "Your Majesty, the country and location are different, and the strategies used are also different, and it is impossible to defeat the world with one tactic. ”

Li Shimin frowned and said, "Why not?" As long as we come and go like the wind, it is impossible for the Goguryeo people to catch the traces of our Tang army! ”

Li Dongsheng said: "Your Majesty, Duke Wei and Huo Qubing can sweep the grassland, first of all, the number of people they command is small, at most a few thousand, and they can command it handy, pointing where to fight." The second is that the grasslands are endless, suitable for the assault and retreat of the cavalry, and the third is that the grasslands are sparsely populated, and every tribe is far away, and no news can be transmitted, so they can go deep behind the enemy and be invincible. The most important thing is that these people's logistics can be maintained only by fighting to feed the war.

Goguryeo is different, they are too influenced by the culture of the Central Plains, and many places learn from the Tang Dynasty, so their country is centered on the city like the Tang Dynasty. Second, the Goryeo people are brave and aggressive, and stalking, if you want to use a cavalry deep behind the enemy, the few people are basically sent to death, and the logistics can't keep up with the large number of people, those Goguryeo have strong cities, and when they get to the city of Goryeo, as long as a city can't be defeated, then we may have to follow in the footsteps of the Sui Dynasty and taste defeat! ”

Li Shimin reluctantly accepted Li Dongsheng's statement, in fact, he has been on the battlefield for a long time, and he knows everything Li Dongsheng said, he just wants to find someone to help him make up his mind.

In the following days, Li Dongsheng could not escape the emperor's poisonous hands, and was always held by his side, and saw how the highest organ of the Tang Dynasty operated. He knew that this was Li Shimin's way of cultivating his view of the overall situation and handling problems with high-level officials, so as to pave the way for him to enter the center in the future.

Li Dongsheng has grassroots work experience and experience as a military commander, and now what is lacking is this, he just observed the handling method of Changsun Wuji on the sidelines, and then regressed to the reasons, and analyzed why they used this method to solve this problem? If it were me, how would I solve it, and how would my approach differ from his? Which one is better?

Li Dongsheng's progress is rapid, from the beginning of the silent learning, to the later active consultation, asking for advice, I really feel that I have benefited a lot, but he will also take the initiative to propose solutions to problems in some things.

For example, if there is a logistical proposal that due to the cold and slippery roads, and the heavy snow is closed, all the materials are difficult to transport. Li Shimin raised his hand and smashed a teacup: "The soldiers are fast, but now they are as slow as a snail, do you still have to stop and wait?" Can you afford to take responsibility for delaying the military plane? ”

Looking at the logistics staff's face like earth, Li Dongsheng couldn't bear to say: "Is it because the snow is so heavy that you can't leave?" Are there any other problems? ”

"There are no other problems, now the materials can't be transported, the snow is half a person high, and the official road has to march again, so I really can't go!"

"If that's all there is hope for." Li Dongsheng thought for a while and said: "We can make a simple climbing plow, and the problem will be solved!" ”

"Climbing the plow? What is it? From Li Shimin to everyone below, they were confused and didn't know what he was talking about.
