What Li Yuan could do was to try his best to arrange for the scouts to come back every day to report on the progress of the troops.

"Father, the cavalry guards stay outside for a longer time. If they are discovered by the enemy, it will probably be very dangerous. Should they be reminded?" Li Yuanji said.

Li Yuanji rarely thinks about problems seriously.

Li Yuan smiled and said, "The Cavalry Guard is His Majesty's Imperial Guard. With their strength, even if they encounter Goryeo soldiers and horses, Yuwen Chengdu wants to see the most. We should not ask about it. This will not benefit the Li family."

"As for the other side's soldiers, you also know their purpose. Their courage is not as good as it shows. Haven't they chosen to stay outside these days?"

Li Yuanji thought about it, even though those tens of thousands of people came back late these days, they finally came back, not like Yuwen Chengdu's Knights went out and didn't come back.

In fact, what he was thinking about was not that, but just wanted to ask for a fight based on this topic.

Seeing that his father seemed to be in a good mood, he took the initiative to say, "Father, when will we go to fight? My son Yuan is the pioneer."

When Li Yuan heard Li Yuan say this, his expression changed instantly, and he sighed in his heart with a cold face. He really had no hope for Li Yuan Ji, he was simply a skin.

Nothing can be used to everything.

"Do you know why my father didn't stop them from going out to attack?" Li Yuan asked suddenly.

Li Yuanji really doesn't know that he likes to think about these things in his daily life, and whenever he wants to use his brain, he will bring them by his elder brother. Now he can only rely on himself, so he can think too.

"Don't my father dislike them for consuming food, right?" Li Yuanji replied hesitantly.

Li Yuan's eyes suddenly lit up, and he suddenly realized that his third son didn't seem to be too stupid either.

"You are right, this is one aspect, but it is also the most important aspect." Li Yuan continued.

Then he took out the statistics on food consumption, which included the chances of daily food expenditure. After statistics, it was found that when the cavalry guards were dispatched, the food consumption would be reduced by a large part of the day.

Especially in recent times, after investigation, we found out that the food harvested by the Xiaoqigu itself was enough for them to eat, which was equivalent to using the method of fighting to support them to be self-sufficient.

Now, in the same way, let the new soldiers go out, and like the cavalry guards, they will also gain something.

Li Yuan explained the matter to Li Yuanji.

"Father, in this case, why don't the Li family's soldiers use war to support the war?" Li Yuanji said in confusion.

"Because our responsibilities are more important than them. As long as the Li family soldiers and horses stick to the shore, the emperor will continue to transport troops and food. Only by sticking to the Li family soldiers and horses can they get the greatest value."

Li Yuanji couldn't understand everything that Li Yuan explained. Anyway, he knew that he wouldn't send troops after he came out of the barracks.

Li Yuan originally wanted to test Li Yuanji to see if he suddenly became enlightened, but unfortunately, he knew later that it was not his son who had become smarter, and he didn't feel much disappointed.

"Commander, I found a scout in Goryeo, and the man had already caught it." The guard suddenly came in and said.

Li Yuan immediately calmed down and asked the guard to bring the people in.

Scouts attacked the barracks at night?

Li Yuan wanted to get more information. When he saw the scout of Goryeo, he found that the person was injured. He could persist until now and could only say that he was very strong in his body.

As a result, Ula said a lot of words, but Li Yuan died before he could understand. He saw a letter he took out.

After opening it, I found that I couldn't understand it, so I could only ask a translation.

"Duke, this is a letter of invitation written by King Rongliu."

Li Yuan wanted to tear the letter apart, but suddenly he thought that the Goryeo scout just now was not their people, so there must be chaos in the Goryeo capital at this time.

With his knowledge, this kind of thing is not difficult to guess.

But he couldn't decide on such a matter of seeking peace, which meant that King Song Liu's letters were of no use to him, and the battle would not stop, at least not now.

After a few days, he was still safe and sound. He came to Hu'er again to transport troops and food. After leaving, Li Yuan brought back the letter of Rongliu's request for peace.

Half a month later, Emperor Yang of Sui saw King Rongliu's letter of peace and agreed immediately, and the conditions were simply too good.

Not only did he pay tribute, he directly asked the Sui State to send troops to build a barracks in Goryeo's country. Now the shore occupied by the Sui State's troops is already from the Sui State, with the premise that the war is stopped.

Emperor Yang of Sui immediately became anxious to discuss the matter, and Li De was also asked to go there. When he heard that King Chenliu asked him to get along, he knew that it was Li Yuan's intention.

The purpose is very simple. The victory of this battle is all about logistics. He was worried that the court would drag him down. If there was a problem with a decision, they would be trapped in Goryeo.

Li Yuan was very smart and used this book of peace to make the emperor who was very happy to give up his troops immediately, so that he could return naturally.

The ministers gathered together and it was noisy, and no one could make any decisions, so they had no results after a long time. Instead, Emperor Yang of Sui felt a little headache.

"Li De, what do you think of King Rongliu's blessing?" Emperor Yang of Sui asked suddenly.

Li De didn't expect that the emperor would ask him what the Sui court meant, maybe he just asked casually.

The courtiers' eyes were all focused on Li De. It was not appropriate not to say it now. Although they didn't want to pay attention, there were so many people watching it, so how could they not say anything?

He believed that he was never a stage fright.

"In this battle, the troops of the Sui Kingdom have the upper hand, so it is better to gain greater benefits. Is Your Majesty satisfied this way?" Li De said and turned into a rhetorical question.

Emperor Yang of Sui instantly understood what Li De meant. Think about it, Li De was such a person, caring about interests like a businessman, and it was true. Now that the army and horses of the Sui Kingdom have the upper hand, it would be inappropriate to only obtain this benefit.

You should know that the materials and money consumed by assembling 600,000 troops are huge. If he cannot get the capital, he will feel that he will lose.

"Li De, you are right. Since the other party is seeking peace, as a country of etiquette, I will send envoys to you first. Lu Fulin will leave this matter to you." Emperor Yang of Sui said.

Lu Fulin felt bad in an instant. When he visited the belligerent country, he still went to compete with the other king for profit. The more he thought about it, the more he became, the more he became afraid.

"I received the order." Lu Fulin didn't have any confidence to say no.

The emperor said he had to go.

Lu Fulin looked at Li De with his eyes, and happened to find that Li De was also looking at him, and he was immediately a little embarrassed.

Li Deke didn't have so many ideas. What decision did Emperor Yang of Sui have to do with him. His purpose was to help his father-in-law.

That's it.

The envoy will continue when the envoy is on mission. If the negotiations are reached, I believe that the Sui army will come back soon. If it is not done well, Yuwen Chengdu and the Knight Guards will be kept.
