Li Shimin was a little skeptical about this matter, but seeing what Li Muyun said with confidence and sereneness made him a little confused.

After a while, he shook his head and said, "Since you said that, I will let them try it back. However, the shelf you sent yesterday is also related to the gunpowder you mentioned?"

"Uh..." Li Muyun whispered: "That, that actually has nothing to do with gunpowder. It's really just a small upgrade. I'm not saying that if we really want to attack Goguryeo, these equipment are really one level away, whether it's transportation or combat effectiveness."

Li Shimin's face turned dark. Goguryeo was originally a big trouble in his heart. Now Li Muyun said this and was more like a slap in the face: "Then according to you, I must be no match for Gao Jianwu."

"Brother, you are an old war person. I know that I don't mean that." Li Muyun said.

Li Er was still a little unhappy: "What do you mean?"

Li Muyun said: "Brother, fighting is not like fighting between two people. It is about the right time, place and people. But there is an old saying that it is better to be in a good place, and places are not as good as people. I saw the broken place in Goguryeo last time. I won't talk about the weather, just say that this place is a big challenge for us."

"The roads in the broken place are narrow and complicated. What you just walked may be the official road, but the next moment may become a rural road. The road just now is still flat, but the next moment may become bumpy."

"This kind of place is a huge challenge for troops to march. If it is just a single soldier, it may be no problem, but if large-scale ordnances are transported in, the time it takes will undoubtedly increase exponentially."

"Brother, this is just a matter of geographical advantage. If you add the time of the six-year summer and six-year winter in Liaodong, this battle really needs to be fought. It is absolutely impossible not to prepare well."

Li Shimin's face was so gloomy that he could almost twist out water, but he had to admit that Li Muyun was right. If the conditions in Goguryeo were really so bad, it would be equivalent to defeating his advantage of being the most important and powerful. As long as the speed of advancing slowed down, Goguryeo could take advantage of the winter to calm down.

Depressed for a long time, Li Er sighed: "What do you mean? Should I just watch Gao Jianwu's child show off his power in Liaodong? Not only can I beat him, but I also have to support him?"

"The emperor brother, the so-called warriors are good at fighting and defeating others' soldiers without fighting. Fighting and killing is something that barbarians do. We are civilized people, how can we do such a nameless thing? I have three strategies here. You might as well consider one or two."

"Tell me, let me see what good ideas you have."

Although Li Shimin did not think that Li Muyun's method was reliable, it was always good to listen to more suggestions.

Li Muyun smiled and turned his head to yell at the little eunuch who was serving him: "Go and make some tea, you should be quick and have good tea."

Hey, this bastard, just gave him a good look, he pretended to be a silly! Li Er glanced at Li Muyun with contempt, waved his hand to the little eunuch helplessly, and signaled him to do what he wanted.

After a moment of silence, Li Muyun opened up the conversation.

"Brother, I still have the same old saying, "I have to be strong on my own, and developing our own military power is the fundamental reason. Gunpowder must speed up the research progress. As long as it is researched, it will definitely give a strong shock to the surrounding countries. This is also my first idea, a threat of force."

"Don't look at the moment when gunpowder can only be used to blow up the city gate. In fact, as long as this thing is used well, let alone the city gate, even the city wall can still be blown up. And we don't have to worry about the city gate and the city wall. At any time, siege is actually a subversive strategy."

"So my brother thinks that at this time, we should be better off getting some simple gunpowder weapons out, and then holding an exercise to invite all the envoys from neighboring countries to let them see the military power of our Tang Dynasty. This will make them die of provocative thoughts, and will also increase morale. Even if they really fight and have a strong military power, they can still be as powerful as a bamboo shoot."

"As for the second, it is still related to improving military strength, but we must take a two-pronged approach. By doing business with Goguryeo this time, we can renovate the roads in Goguryeo with the excuse of increasing transportation capacity to facilitate the future attack on Goguryeo."

"In addition, we can also buy some people and turn them into ours. When the army arrives, with the cooperation of their internal personnel, I believe that there is no need to spend any effort to overcome some important obstacles.

"But this requires greater energy to be invested. Not only to increase military strength, but also to send some detailed works to Goguryeo to examine the landform in detail and prepare for future attacks."

"As for the last point, it may take longer, that is, to borrow this opportunity to do business, we sacrifice some interests, establish the prestige of the Tang Dynasty among the Goguryeo people, so that their people can trust us, and thus give up their own court."

"At the same time, we must increase our efforts to attract Goguryeo talents, give them the opportunity to study and settle down in the Tang Dynasty, and turn them into our people. As one goes up and down, I believe that Goguryeo will be in name only in decades."

Li Shimin listened to Li Muyun talking there in a daze, almost unable to believe his ears.

Is this the unreliable bastard at the beginning? Apart from the first one, the first one, the last two methods are simply a stroke of magic.

As the Emperor of the Tang Dynasty, Li Shimin was not stupid. All he lacked was a reminder. As long as there was an introduction, he could think of many things. Once three strategies were made, Li Er suddenly realized how to deal with Goguryeo. He was no longer as entangled as before. In a short period of time, he even thought of some more detailed questions.

But if you say a thousand words, His Majesty Li Er still thinks that the saying "The iron must be strong himself" is more reasonable. What is peaceful transition and what is two-pronged approach is actually nonsense. Who can defeat you without strong military power?

After sending Li Muyun away, Li Shimin locked himself in the yard and thought about it all day, and finally made up his mind to try the gunpowder weapon that Li Muyun mentioned.

Since that thing can kill 20,000 Xueyantuo cavalry at a time in Shuozhou, there is no reason why it can only be used to bomb the city gate in his hands.

An edict was sent overnight, and it was sent to the hands of Prince Li Chengqian in the middle of the night.

The next morning, Li Dejian, who was idle, was recruited into the Eastern Palace by the prince and assigned a new task.
