What do I think? What can I think? What do I dare to think? Li Dongsheng complained in his heart, but said quietly on his face: "The major affairs of the military state are the affairs of the prime ministers and His Majesty. Weichen didn't dare to say more! ”

"Don't be sloppy with me!" Li Shimin saw that Li Dongsheng belonged to a donkey, and he wouldn't leave without whipping him: "If you don't say something today, don't leave." ”

Li Dongsheng was speechless for an instant, what kind of grudge do I have with you, you want to treat me like this. He smiled bitterly and said, "Your Majesty, this matter is too important, and it is really not something I can participate in." Moreover, if the prime ministers are not approached for major military affairs, the system is not compatible. ”

"Don't put gold on your face, it's just that I'll talk to a courtier, and any military affairs will be regarded as idle chat." Li Shimin picked up the tea made by Wang De, took a sip and said: "Anyway, I won't approve the chapter today, just consume it with you, see if you say it or not." ”

The wise and martial emperor of the Tang Dynasty actually played a scoundrel, Wang De saw that Li Shimin was in a good mood, which was a rare relaxation since the prince's rebellion, and he also smiled and joked: "Lantian Hou, I also heard that you think about things in a unique way, and you also say it to let us gain knowledge." ”

Looking at this shape, it is not okay not to say something today, Li Dongsheng smiled bitterly: "Your Majesty, Weichen thinks that Goguryeo is a big disaster for the Tang Dynasty, so it must be destroyed!" ”

Li Shimin said lazily: "You don't need to say this, the Manchu Dynasty knows all the civil and military affairs, and say something useful." ”

"yes. Lantian Hou doesn't want to let us down. "Wang De is like a compromiser.

"Your Majesty, since everyone thinks that Goguryeo must be fought, there is a question of how to fight it." Li Dongsheng saw that he couldn't escape today, so he had to tell the practice of the history books of later generations: "So Weichen thought of a few ways for His Majesty's reference." ”

Li Shimin pretended not to care: "Let's hear it." ”

"Your Majesty, Goguryeo is a small country in the middle of nowhere, and it is located at a high altitude, and the climate is cold, so it is impossible to use troops in winter. So although he is sometimes stronger, he will never be able to be a big country. Li Dongsheng began to talk eloquently: "And my Datang is different, under the leadership of His Majesty, my Datang national strength is thriving, whether it is manpower, military power, or financial resources, it is not comparable to that little Goguryeo." ”

Seeing Li Shimin's brows furrowed, these are all things that everyone knows in their hearts. It's just picking up people's teeth. Li Dongsheng continued: "The former Sui did not see through this and mobilized the strength of the whole country to attack him, but Yang Guang was indecisive, and something happened to his rear, so he failed. ”

Now Wechen thinks that the method of attacking with a large army is not suitable for attacking a country like Goguryeo. Such mobilization of personnel and material resources would be a huge waste and would cause huge casualties, and I am afraid that this is the concern of the ministers of the DPRK and China. ”

Li Shimin and Wang De were interested when they heard this, and stared at Li Dongsheng with blazing eyes: "Then how to fight?" ”

"It's to fight an unconventional special operation!" Li Dongsheng said: "It is to use the strengths of my Tang Dynasty to deal with the shortcomings of Goguryeo, and strive to destroy the country with the least cost and the least casualties." ”

"Cut, isn't it what the military book says about taking one's own strengths and attacking the other's shortcomings, I thought it was." Li Shimin said disdainfully.

"Yes, these eight words are easy to say, but the real difficulty is knowing your strengths and the weaknesses of the other party." Li Dongsheng said with a smile: "Your Majesty, fighting a war is not a concept in the art of war, but the real use is in one mind. Goguryeo's shortcomings are actually obvious at a glance. It is located in eastern Liaodong, the climate is bitterly cold, crops can only grow once a year, and where they have more mountainous areas, the land that can be cultivated is limited, even if the land is fertile, the yield is extremely limited. ”

Li Shimin and Wang De nodded violently when they heard this, this idea has really not been considered.

"The population of Goguryeo is much smaller than that of my Tang Dynasty, whether it is spring planting or autumn harvest, men are the main laborers in the family, so my suggestion is to take advantage of the spring planting and autumn harvest every year, our Datang will send a small force of cavalry into Goguryeo to harass constantly, and in a few years, Goguryeo will definitely be starving everywhere, and it will be decided by a war at that time."

"Yes, everyone has to eat. In a few years, they must have a famine, and the people will not have enough to eat, where will they have the strength to fight? Li Shimin pondered: "Liaodong sent a large army to blockade again, and not a single grain of grain was allowed to enter Goguryeo. ”

"Your Majesty, the navy will also be sent out to prevent Fusang from bringing food by ship."

"You can also support Baekje, as well as Silla and some of their weapons and armor, encourage them to attack Goguryeo, and let them fight dog-eat-dog for a while on that peninsula, and we Datang can sit on the mountain and watch the tiger fight, and then the initiative will be mine, and when to fight, it will be my Datang who has the final say." Seeing that Li Shimin has been fully involved in the future planning, Li Dongsheng said in his heart that it feels really good to use your ideas to fool you.

In history, Li Shimin did this, he sent troops from Luoyang to conquer Goguryeo in February of the 19th year of Zhenguan, although he laid down a lot of Goguryeo cities, and also killed a lot of Goguryeo people, but the cold winter saved Goguryeo's life, at that time there was no cotton jacket to keep out the cold, in order to prevent the repetition of Yang Guang's mistakes can only return to the court.

This expedition to Goguryeo was the only time that Li Shimin took the throne as emperor, but he did not fulfill his wish, which shattered his myth of invincibility and made Li Shimin a stain in his life. So he began to use unconventional warfare against Goguryeo in the second year, Niu Jinda, Li Ji, Cheng Mingzhen, Su Dingfang and other famous generals of the Tang Dynasty all brushed up on this copy of Goguryeo, from ordinary to epic, anyway, the Sanguang policy was completely implemented in Goguryeo.

After going to do it for several years, Goguryeo was embarrassed, and sent people to the Tang Dynasty to beg for mercy, and even the prince was sent to Chang'an as a hostage. But Li Shimin ignored it and continued to do it without stopping. Until after his death, Tang Gaozong Li Zhi also inherited the same policy, and after a few more years, he easily destroyed Goguryeo, which had only one breath left.

Wang De's eyes were different when he looked at Li Dongsheng at this time, and he had been troubled by sending troops to Goguryeo for so long, and Li Dongsheng solved it in a few words, and his views were novel and highly operable. What a talent.

"What else?" Li Shimin is now well-versed and in a good mood.

"Your Majesty, there is also the soldier who is going to harass Goguryeo, and you can do without the soldiers of the government or the sixteen guards." Li Dongsheng made a new suggestion.

"Don't use them? So who will attack it? Li Shimin said suspiciously: "You don't need soldiers to fight?" ”
