Li Shimin wanted to use military force against Goguryeo, but Li Xiu and Changsun Wuji were not surprised by this. After all, it has been a day or two for Li Shimin to have such thoughts, so they can naturally see that.

However, Changsun Wuji was very cautious about this matter. Although he did not object explicitly, Li Xiu could see that he did not want to attack Goguryeo, at least not now. Although the Tang Dynasty is becoming stronger and stronger, it has just lived a few days of good life, and this kind of prosperity is not stable. Of course, if Goguryeo can be destroyed in one fell swoop, it will definitely accelerate the arrival of the prosperity. However, if there are any setbacks, it will greatly hit the reputation of the Tang Dynasty and even affect the development of the domestic market.

In fact, Changsun Wuji's idea also represents the ideas of most ministers. Firstly, although Goguryeo was not the strongest opponent around the Tang Dynasty, he defeated Yang Guang's army three times, resulting in the burial of countless Central Plains athletes in Liaodong. No one can guarantee whether Li Shimin would repeat the retracement of Yang Guang? Secondly, the Tang Dynasty was no longer as good as before. In the early days of the Tang Dynasty, the country was poor and was not scrupled, and he had no scruples to launch a foreign war. Anyway, he was barefoot and was not afraid of wearing shoes. However, now the Tang Dynasty is getting stronger and he has become a shoe-wearing person, so there are inevitably too many bonds when launching a war.

Li Shimin also knew very well about the above, so he left Changsun Wuji and Li Xiu alone for negotiation in order to get their support first. However, Changsun Wuji was obviously hesitant, so he also looked at Li Xiu at this time, hoping to hear Li Xiu's opinion.

Li Xiu pondered for a moment, and finally suddenly looked up at Li Shimin and said, "Your Majesty, I think Goguryeo is a major problem in the Northeast. If you don't get rid of it for a day, the Northeast will be in a day of restlessness, so you must fight!"

Li Shimin didn't expect that Li Xiu would support him so firmly, and he couldn't help but show a surprise expression, but Changsun Wuji was shocked and couldn't help but say, "Why are you, son-in-law..."

However, before he finished speaking, Changsun Wuji suddenly closed his mouth because he found that Li Xiu had a wink at him, which made him immediately understand. Li Xiu then said: "It must be a fight, but what I am thinking about now is how to fight?"

"Oh? Is the prince-consort a good idea?" Li Shimin didn't rub the sand in his eyes, and he also noticed the small movements between Li Xiu and Changsun Wuji. He said a little unhappy at the moment, because this usually happens, which means that Li Xiu and Changsun Wuji have reached an agreement, and his own ideas may be rejected by them.

"There is no question about Gao Jue, but I think that if we deal with a country like Goguryeo, if we gather a large army to attack directly like before, even if we can conquer Goguryeo in the end, we may have to suffer a lot of casualties!" Li Xiu said with a smile at this time.

"What does it mean? Isn't it the same in war?" Li Shimin couldn't help but frown when he heard Li Xiu's words. He felt that Li Xiu had something in his words, and even he couldn't understand the intentions.

Seeing that Li Shimin didn't understand, Li Xiu couldn't help but smile indifferently. He did not explain directly at the moment, but instead 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 was stunned for a moment, and then he said in confusion, "Isn't this obvious? Our Tang Dynasty has a strong national strength and is the most powerful empire in the world, while Goguryeo is just a small country. If our Tang Dynasty sends troops, it will definitely be destroyed in one fell swoop!"

"Haha, Your Majesty is right. Our Tang Dynasty is a big country, while Goguryeo is a small country. The reason why a big country is called a big country is because its national strength is stronger than other countries. This national strength also includes many aspects. The most important of them are manpower, material resources, financial resources, etc., as well as the ability of the country to mobilize national strength in all aspects. From this perspective, there are almost no country in the world that is the opponent of our Tang Dynasty!"

Li Xiu first praised the national strength of the Tang Dynasty, but then suddenly smiled strangely again and said, "Since my national strength of the Tang Dynasty is stronger than the other party, we can use another way of war to attack the other party, instead of sending a large army to fight directly like before!"

"Another way of war?" When Li Shimin and Changsun Wuji heard this, they couldn't help but look at each other, and even more puzzled expressions appeared on each other's faces.

"Yes, I call this method of war asymmetric war. Simply put, it means using the strengths of our Tang Dynasty to attack Goguryeo, so as to achieve the greatest result at the smallest price!" When Li Xiu said this, the smile on his face became even more sinister. In fact, this method of war was not invented by him, nor was it only existed in later generations. Some people even used it in the Tang Dynasty, but the name Asymmetric war was only available in later generations.

"It sounds simple to say with one's own strengths and to attack the other's weaknesses, but it is not that easy to do, right?" Li Shimin thought Li Xiu had some ideas, but he did not expect that he had not left Fan Chou, who was a military strategy. He could also think of this method, but whether he could do it was two different things.

"Your Majesty, it is actually very simple to do it. As far as I know, Goguryeo is located in Liaodong, where half of the year is in the cold, and crops can only grow for one season. For example, wheat in our Central Plains can be ripe twice a year, but wheat in Goguryeo can only ripen once a year. Even if their land is fertile, the yield is limited. In addition, there are few people in Goguryeo, and men are the main laborers in the family. During the autumn harvest, men are the main force. If we take this opportunity to send a small group of troops to enter Goguryeo to harass for several years, what does Your Majesty think?" Li Xiu smiled and said.

When Changsun Wuji and Li Shimin heard this, they couldn't help but look at each other again. They both saw a little shock in each other's eyes. They didn't expect that Li Xiu's plan was so cruel. They sent a small group of troops during the autumn harvest of Goguryeo, and then killed and set fire in Goguryeo. If Goguryeo wanted to fight back, they would definitely need to gather troops. In this way, there would be a lack of labor in the fields and the grain output in that year would also be greatly reduced. If it lasted for a few years, it would be possible that Goguryeo would collapse without the Tang Dynasty's troops.

"Is this... a bit unkind and righteous? And doing so will definitely arouse resentment from the people of Goguryeo to the Tang Dynasty. I'm afraid that even if it is defeated in the future, it will not be difficult to manage?" Li Shimin said hesitantly at this time.

When Li Xiu heard Li Shimin's words, he secretly curled his lips. Everyone is qualified to say this, but Li Shimin is not qualified because Li Shimin did this in history. It can be said that he is the real implementer of the asymmetric war!
