Li Shimin wanted to use troops against Goguryeo, and Li Xiu and Changsun Wuji were not surprised by this, after all, Li Shimin had this kind of mind for a day or two, and the two of them could naturally see it.

It's just that for this matter, the eldest grandson Wuji is very cautious, although he did not oppose it openly, but Li Xiu can see that he does not want to attack Goguryeo, at least not now, although the Tang Dynasty is becoming stronger and stronger, but it has only just lived a few good days, and this kind of prosperity is not stable, of course, if it can destroy Goguryeo in one fell swoop, it will definitely speed up the arrival of the prosperous era, but in case of any setback, it will hit the prestige of the Tang Dynasty, and even the domestic development will be affected.

In fact, the idea of the eldest grandson Wuji also represents the thoughts of most ministers, first, although Goguryeo is not the strongest opponent around the Tang Dynasty, but it defeated Yang Guang's army three times, resulting in countless Central Plains athletes dying in Liaodong, no one dares to guarantee that Li Shimin will not repeat Yang Guang's mistakes? Second, Datang is not better than before, in the past, the Tang Dynasty was established, the country was poor and white, and there was no scruple about launching foreign wars, anyway, barefoot was not afraid to wear shoes, but now Datang's national strength is getting thicker, and he has become a shoemaker, so it is inevitable that there are too many fetters when launching a war.

Li Shimin also knew the above very clearly, so he left the eldest grandson Wuji and Li Xiu alone to negotiate, in order to get their support first, but the eldest grandson Wuji was obviously a little hesitant, so he also looked at Li Xiu at this time, hoping to hear Li Xiu's opinion.

I saw Li Xiu pondering for a moment at this time, and finally suddenly looked up at Li Shimin and said: "Your Majesty, the minister thinks that Goguryeo is a big disaster in the Northeast, and if it is not eliminated for a day, the Northeast will be restless for a day, so it must be fought!" ”

Li Shimin didn't expect Li Xiu to support him so firmly, and he couldn't help but show a surprised expression at the moment, but the eldest grandson Wuji was taken aback, and even couldn't help but say: "Why are you ...... the horse?"

But before he finished speaking, the eldest grandson Wuji suddenly closed his mouth, because he found that Li Xiu glanced at him, which also made him understand immediately, only to see Li Xiu then continued: "The fight is definitely going to be beaten, but what the minister is thinking about now is how to fight?" ”

"Oh? Does the colt have any high opinions? Li Shimin's eyes did not rub sand, and he also found the small movements between Li Xiu and the eldest grandson Wuji at the moment, and he was also a little unhappy at the moment, because generally this situation occurred, it meant that Li Xiu and the eldest grandson Wuji had reached an agreement, and their ideas might be rejected by them.

"Gao Jian can't talk about it, but the minister thinks that against a country like Goguryeo, if he gathers a large army to attack directly like he did with the Turks in the past, even if he can defeat Goguryeo in the end, I am afraid that he will have to suffer a lot of casualties!" Li Xiu said with a smile at this time.

"What do you mean, isn't it always like this in war?" Li Shimin couldn't help frowning when he heard Li Xiu's words, he felt that Li Xiu had something to say, and even he couldn't understand the intention.

Seeing that Li Shimin didn't understand, Li Xiu couldn't help but smile indifferently, and didn't explain directly at the moment, but asked: "Your Majesty, do you know what is the biggest difference between our Tang Dynasty and Goguryeo?" ”

"The biggest difference?" Li Shimin didn't expect Li Xiu to ask this, he couldn't help but be stunned for a moment, and then said with some puzzlement, "Isn't it obvious, our Tang Dynasty is strong and powerful, and it is the most powerful empire in the world, while Goguryeo is only a small country, if I send troops to the Tang Dynasty, it will definitely be destroyed in one fell swoop!" ”

"Hehe, Your Majesty is right, our Datang is a big country, but Goguryeo is a small country, the reason why a big country is called a big country is because the national strength of a big country is stronger than other countries, and this national strength also includes many aspects, the most important of which is manpower, material resources, financial resources, etc., as well as the country's ability to mobilize all aspects of national strength, from this point of view, there are almost no countries in the world that are my Datang opponents!"

Li Xiu first praised Datang's national strength loudly, but then suddenly smiled strangely again: "Since my Datang's national strength is stronger than the other party, then we can completely use another way of war to attack each other, instead of directly sending a large army to conquer and suppress it like before!" ”

"Another way of warfare?" When Li Shimin and Eldest Sun Wuji heard this, they couldn't help but glance at each other, and each other's faces showed even more puzzled expressions.

"Yes, I call this method of war asymmetrical warfare, to put it simply, it is to use the strength of our Tang Dynasty and the shortcomings of attacking Goguryeo, so as to achieve the greatest result at the minimum cost!" When Li Xiu said this, the smile on his face was even more insidious, in fact, this method of war was not invented by him, nor was it only available in later generations, and even some people used it in the Tang Dynasty, but later generations had the name asymmetric war.

"It's easy to say that you are strong and you are short to attack others, but it's not so easy to do, right?" Li Shimin thought that Li Xiu had some high opinions, but he didn't expect that he still didn't get out of the art of war, and he could think of this method, but whether he could do it or not was two different things.

"Your Majesty, in fact, it is very simple to do, as far as I know, Goguryeo is located in Liaodong, where half of the year is in the cold, crops can only grow one season, for example, the wheat in our Central Plains can be harvested twice a year, but the wheat of Goguryeo can only be ripened once a year, even if their land is fertile, but the yield is limited, in addition, there are few Goguryeo people, men are the main labor in the family, and men are the main force during the autumn harvest, if we take advantage of this opportunity, we send a small force to enter Goguryeo to harass, And if it goes on for several years, what does Your Majesty think? Li Xiu said with a smile on his thoughts.

When the eldest grandson Wuji and Li Shimin heard this, the two couldn't help but look at each other again, and each other saw a little shock from each other's eyes, they didn't expect Li Xiu's strategy to be so ruthless, taking advantage of the autumn harvest of Goguryeo to send a small force of troops, and then kill people and set fire in Goguryeo, if Goguryeo wants to fight back, it must be necessary to gather troops, so that there will be a lack of labor in the fields, and the grain output of the year will be greatly reduced, if it lasts for a few years, I am afraid that without the Tang Dynasty to send troops, Goguryeo itself will collapse.

"This ...... Isn't it a bit unkind, and doing so will definitely arouse the resentment of the Goguryeo people against the Tang Dynasty, I'm afraid that even if it is defeated in the future, it will not be easy to govern? Li Shimin said with some hesitation at this time.

Li Xiu secretly pouted when he heard Li Shimin's words, everyone is qualified to say this, but Li Shimin is not qualified, because Li Shimin in history did this, it can be said that he is the real implementer of asymmetric warfare!
