The winter in Goguryeo is really cold, with more than minus 20 degrees Celsius.

In order to hurry, Li You came on horseback, he was really frozen, and when he heard Li Shimin's words, he was not polite, he really sat by the fire and reached out to roast the fire.

Li Lizhi brought him a cup of tea, and also sat by the fire, talking with him.

Li You held the teacup in both hands and said, "This ghost weather, it's really enjoyable to be able to drink a cup of hot tea!" ”

Li Shimin chatted with Li You for a while, and then began to talk about business.

Li Lizhi saw that they were talking about business, and said to Li You: "Fifth brother, you talk about things, little sister, I will go down first, and go to prepare a reception banquet for you." ”

Li You smiled: "The fifth sister still understands me and knows that I love to eat, thank you." ”

Li Shimin sent people to call Li Jing, Li Ji, Li Daozong and others to listen to Li You's report together.

Li You first reported on the great victory of the Northwest Province in the invasion of the Graham Kingdom in western Pakistan, praised the achievements of Cheng Yanjin, Xue Rengui and others, and invited merit and rewards for the soldiers who participated in the war.

He then reported on the strategies and tactics adopted by the Eastern Expeditionary Army in the campaign against Baekje and Silla, as well as the merits of Hou Junji, Cheng Chuliang, and Wang Xuance.

Li Shimin and others have already read the battle report and have a basic understanding of these situations. However, they still gave a positive affirmation to Li You's strategy of military, political, diplomatic, and economic integrated warfare.

Li Ji said: "The climate and terrain of Goguryeo are indeed difficult to adapt, and the strategy of one-game warfare has dealt a fatal blow to the Goguryeo people, and many Goguryeo people come to surrender to the Tang army almost every day, just for a hot meal." ”

Li Jing said with a smile: "If this continues, the Goguryeo people won't be able to last long." ”

Li Daozong also said optimistically: "Yes, the minister thinks that the Goguryeo people can't even survive this winter. The strategy of one-in-one warfare seems to have been slow to take effect, but in fact, it is not, not only has fewer casualties than conducting large-scale field battles, but is also more capable of depleting the strength of the Goguryeo people. Multiplier. ”

Li Shimin concluded: "Why did Li You's strategy always achieve a major victory with a small force?

In fact, before the start of the war, the strength of the Tang Army was not strong, and under the guidance of the strategic thinking of military, political, economic, and diplomatic integration, the strength of the Tang Army was constantly growing. When it comes to the specific battle, it is to fight more and fight less, which is the key to victory in the end.

The capture of the Western Regions, Persia, Baekje, and Silla was accomplished by using the power of the vassal states and the locals. ”

Li Jing exclaimed: "Your Majesty, Your Highness only relied on 10,000 Tang troops and tens of thousands of troops of vassal states in the Western Regions back then, and later fought hundreds of thousands of troops.

This time in Baekje, they had less than 10,000 Tang troops at the beginning, but now they have hundreds of thousands of troops with the participation of Silla and Baekje people.

At this point, the old minister was deeply impressed. ”

Hearing everyone praise him, Li You hurriedly said modestly: "Father, my lords, in these places, the sons and daughters have encountered many contradictions in their countries, so they have the opportunity to take advantage of them.

Goguryeo was different, their country was relatively united, and they had to gather a large army to defeat it. ”

Li Shimin smiled: "Okay, don't put gold on our faces." War is first and foremost a matter of strategy, and if the previous tactics are still used in attacking Goguryeo, relying only on the army to attack the Goguryeo, it will inevitably face bloody battles, and the Goguryeo people will still have high morale and stubborn resistance.

After adopting the tactics of one-in-one warfare, the Goguryeo people are now disheartened, and a large number of Goguryeo people fleeing every day, as well as many Goguryeo cities, have taken the initiative to surrender, which has already shown that as long as the correct strategy and tactics are adopted, things can be transformed.

The attack on Goguryeo was already prepared for at least a year to complete. Now it seems that, conservatively speaking, the Goguryeo people will not survive this spring at the latest.

Goguryeo, which the people of the Central Plains have not been able to take for hundreds of years, and Emperor Yang of the Sui Dynasty destroyed the country because of this, will definitely be completely destroyed by the Tang army this time. Ha ha. ”

Li Shimin and others discussed the war in Goguryeo for a while, and the topic turned to scientific and technological inventions.

Li Shimin said solemnly: "Everyone has read the article "Gewu Changes Life" published by Li You in "Datang Daily".

Li You solved the problem of fire protection and the problem of drinking water for the people in Chang'an. These are all caused by the lattice.

I still remember the tragic situation of the burning of Anshi Castle vividly, and the power of Gewu is too great. The radio station invented by Li You this time is a great invention since the ages, and it will have a major impact on all aspects of the life of the whole society.

I think it's time to completely change the way we think about Gewu. ”

Li Jing said: "Yes, in the previous army operations, understanding the enemy's situation and transmitting orders were all done by scouts and messengers, and when the command got the news, it was often a few days or dozens of days ago, and it was impossible to correctly judge what changes had taken place there.

There will be no exemption from military orders abroad. It is because of this situation that the emergency measures are taken.

In the past, the situation of Hou Junji and others' Eastern Route Army was impossible for us to understand here. It will take at least a month to send a messenger and ride a horse and then a boat. Who would have thought that with such equipment as a radio, the situation from hundreds of miles away can communicate with each other at any time. It's just amazing! ”

Li Ji said: "With such equipment, the Tang Army will have a great advantage in future wars. However, there are pros and cons to things, and once such equipment is in the hands of the enemy, it will be difficult to guarantee the secrecy of the actions of the Tang army. Therefore, it should be strictly controlled. ”

Li Shimin said: "I was just worried about this problem, so I specially called Li You over to discuss this matter." ”

Li You reported to Li Shimin and others the management methods for radio station equipment discussed by the ministers in Chang'an.

Li Shimin thought about it again and again, and he decided to move all the personnel who developed the radio station in Kabul, including those craftsmen who participated in the manufacture, back to Chang'an, and let the Baiqi Division supervise the production.

In the future, Li Shimin will be directly responsible for the examination and approval of the distribution and power generation stations, and strict monitoring and strict security should be carried out for the newspaper personnel.

Li You knew that this incident had caused a shock to Li Shimin and others, and it was necessary for him to be so careful. Li You immediately agreed.

After talking about these things, Li Shimin held a reception dinner for Li You and others.

At the dinner, Zhang Guigui was very happy to see Li You, and he said: "Brother You, I have made the first contribution to the attack on Anshi City. Ha ha. ”
