The eldest grandson Wuji insisted on letting Fang Xuanling say it first, and after Fang Xuanling postponed it for a while, he saw that the eldest grandson Wuji was sincere, so he didn't refrain anymore.

"Your Majesty, generals, please see that there are many mountain ranges in the three southwestern provinces, which are not suitable for large-scale mobilization at all, if we want to occupy here, it is already very difficult to send troops in, and the three southwestern provinces are different from the grasslands in the north, the grasslands in the north are flat, and there are many mountains in the three southwestern provinces......"

Fang Xuanling began his speech, first of all, from the aspect of terrain, if we want to occupy this area, the terrain of this area alone is enough for us to drink a pot, no matter how many troops are sent over, it may be a long snake formation, and there is no way to show the advantages of our army.

The second is that there is a miasma in the area, and if our people pass by, it is very likely that they will develop all kinds of diseases, and if they are not well healed, our people may have suffered heavy losses before they meet the enemy's army.

The third is what to do when you knock it down? The local products are not very rich, and the local people's lives are not very good, so we must pay attention to economic benefits when we build a place, and if there are no economic benefits, then it is not a waste of money? Although it expanded the territory of the empire, it was not beneficial to the finances of the entire empire, and in the end it was a big loss.

Although the common people would not say it at the time, when the expenditure on military spending affects the lives of the common people, then I am afraid that the common people will stand up and criticize the government, coupled with the strange problems of the literati of the court, maybe this matter will bring a great crisis of trust to the imperial court, and the common people will think that the decision made by the imperial court is no longer realistic.

The last and most important one, if we send troops this time, it will be a bit of a division, no matter which country we attacked in the past, we could make up a set of doctrines that were beneficial to us, but can we make it up now?

The Nanzhao Kingdom invited His Royal Highness the Imperial Grandson to come over, and it was to prepare to marry the princess of the country to us, but we were thinking about plotting against other people's countries, from which aspect, I am afraid this is unreasonable, right?

Taking 10,000 steps back, even if we can occupy the land of Nanzhao, will we be able to live in peace in our hearts? What impression will we leave on our neighbors? As long as we take a fancy to your land, then we will do whatever it takes to get it.

After Fang Xuanling finished saying this, he went directly to the back and stood up, everything that should be said had already been said, if you insist on attacking, then you can make your own decision, but how many sequelae will there be after the attack, then you people have to solve it yourself.

"Wei Chen added, the current Nanzhao Kingdom is not harmful to us, people pay tribute on time every year, and they give practical benefits, even if we knock this place down, the benefits to us in the end will not necessarily be more than now......

Eldest Sun Wuji never spoke, he thought the same thing as Fang Xuanling in his heart, when Fang Xuanling finished speaking, Eldest Sun Wuji added this sentence, and also made these people present not know what to say, this meaning is also very clear, whether you fight or not are these benefits, why do you need to fight? As long as it is a war, we will definitely have losses, and with losses, what we gain will be the same as before, and may even be lower than before, so what is the meaning of this war?

Li Shimin didn't take this into account before, listening to the two adults finish speaking, Li Shimin also frowned, if you want to analyze it rationally and do not pursue the expansion of the land area, what these two adults said is also a fact.

"You are all calculating economic accounts, have you ever thought that if we take the land of Nanzhao, then we can use it as a base, and even continue to develop in all aspects to the south, then our land area will continue to increase, and then we will not be given a little bit."

Li Xiaogong, as the representative of the imperial court in the military, is of course the representative of the previous generation, and he must be Li Xiang in this life, and he is also very keen on military affairs, although he is not as strong as Li Shimin, but he also wants to build the Tang Dynasty into an unprecedented empire.

Li Xiang once told about the things in the south of Nanzhao, if we can take down Nanzhao, then we can advance to the countries of South Asia, of course, they don't know what South Asia is, but they know that there are countless small jobs there, although the materials are not very rich, but the population is large, and it is still possible to produce food.

Isn't food the most important thing in the age of farming? I heard that there are so many countries over there, and these people are instantly interested, but they didn't expect that there would be obstacles here in Nanzhao Kingdom.

"You should all have listened to what His Royal Highness Taisun said, Weichen did send a lot of secret agents, and they also sent back some news further south, basically the same as what His Highness said, but there is one thing I have to tell you, the people over there live in the deep mountains and old forests, the terrain is complex and changeable, and the weather is humid, can our army really stand it?"

When Li Xiang depicted the situation in South Asia, the imperial court asked Changsun Wuji to send a group of secret agents, and now only half of them have returned, and the rest of them are said to be unsuitable for the climate in the south, and all of them are lost in the south, which can be said to be very large, which is also a reason why Changsun Wuji prevented them from going south.

Speaking of the climate in the south, these people are silent, not to mention the south of Nanzhao, even in some areas of Lingnan in our country, many people can't stand it, when the imperial court sent troops to Lingnan to set up a county, there were indeed many soldiers who lost their lives on the way.

They have not even seen the face of the enemy, it is because of the humid climate in the south that these people have lost their lives, and now they are going further south, if there are too many non-combat attrition, we may be in a state of not being able to go up or down, and then we will lose even more.

Li Shimin thought that today's talks would be very smooth, after all, now that the Tang Dynasty is strong, it has just subdued the countries of the Western Regions, as long as it can pull the southwest into its own territory, this is closer to what Li Xiang said about the begonia, but after listening to the words of the two adults, Li Shimin also fell into deep thought......
