What Li Yuan can do is to wait as much as possible, and someone will come back every day to report the progress of the troops.

"Father, the cavalry guards are staying outside for longer and longer, and if they are discovered by the enemy, I am afraid it will be dangerous, do you want to warn them?" Li Yuanji said.

Li Yuanji rarely thinks about the problem seriously.

Li Yuan said with a smile: "The Xiao Cavalry Guards are His Majesty's forbidden army, with their strength, even if they encounter Goryeo soldiers and horses, it is really what Yuwen Chengdu wants to see the most, so we don't have to ask, this will not be beneficial to the Li family." ”

"As for the soldiers and horses on the other side, you also know their purpose, their courage is not as big as it seems, haven't they chosen to camp outside these days."

Li Yuanji thought about it, although the tens of thousands of people came back late in the past few days, they finally came back, and it was not like Yuwen Chengdu's Xiao cavalry guards who went out directly and didn't come back.

In fact, he didn't think about that, but he just wanted to ask for war on this topic.

Seeing that his father seemed to be in a good mood, he took the initiative to say: "Father, when will we fight, my son Yuan will be the vanguard." ”

When Li Yuan heard Li Yuanji say this, the expression on his face changed instantly, and he sighed in his heart with a cold face, he really didn't have hope for Li Yuanji, he was just a skin.

Nothing is brainless.

"Do you know why the Father didn't stop them from going out to fight?" Li Yuan asked suddenly.

Li Yuanji really doesn't know, he usually likes to think about this, and whenever he wants to use his brain, his eldest brother will bring it, but now he can only rely on himself, so he also thinks about it.

"Father doesn't dislike them for consuming food, does he?" Li Yuanji replied hesitantly.

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

"You're right, it's one aspect, but it's also the most important one." Li Yuan continued.

Then he took out the statistics of food consumption, which had the probability of daily food expenditure, and after statistics, he found that when the Xiao Cavalry Guard went out, the food consumption would be reduced by a large part.

Especially in the last few times, after investigation, I learned that the food harvested by the Xiao Cavalry Guards was enough for them to eat, which was equivalent to supporting their self-sufficiency by fighting and feeding them.

Now, in the same way, let the new soldiers and horses go out, and they will also gain the same as the Xiao Cavalry Guard.

Li Yuan explained the matter to Li Yuanji.

"Father, in this case, why don't the Li family's soldiers and horses use the method of fighting to support war?" Li Yuanji wondered.

"Because our responsibility is more important than all of them, as long as there are Li family soldiers and horses sticking to the shore, the emperor will continue to transport troops and food, and the Li family's soldiers and horses can get the greatest value by sticking here."

Li Yuanji couldn't understand all the things Li Yuan explained, anyway, he knew that he didn't want to send troops when he came out of the barracks.

Li Yuan wanted to test Li Yuanji to see if he suddenly opened his mind, but unfortunately when he got to the back, he already knew that it was not his son who became smarter, and he was not too disappointed in his heart.

"Commander, a Goryeo scout has been found, and he has been caught." The guard suddenly came in and said.

Li Yuan immediately cleaned up his mood and asked the guards to bring people in.

Scouts raid the barracks at night?

Li Yuan wanted to get more information, and when he saw the Goryeo scout, he found that the person who came was injured, and the arrow in the back was able to hold on to the present can only be said to be very strong.

As a result, Ulawala said a lot of words, and Li Yuan didn't understand it, so he lost his breath and saw a letter in his hand.

After opening it, I found that I couldn't understand it, so I had to call a translator.

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

Li Yuan wanted to tear up this letter, but suddenly thought that the Goryeo scouts just now were not their people, so there must have been chaos in the Goryeo capital at this time.

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

But he couldn't decide on such a thing as suing for peace, which meant that King Songliu's letter was of no use to him, and the battle would not stop, at least not now.

After a few days, it was still safe, and Laihu'er came again to transport the soldiers, horses and food, and after leaving, Li Yuan brought back the letter of peace of King Rongliu.

Half a month later, Emperor Yang of Sui saw King Rongliu's peace letter and immediately agreed, and the conditions were not too good.

Don't say that the minister Nagong said, he directly asked the Sui State to send soldiers and horses to build a barracks in Goryeo, and now the shore occupied by the soldiers and horses of the Sui State is already Sui State, provided that the war is stopped.

Emperor Yang of Sui was immediately anxious to discuss things with the ministers, and Li De was also asked to go over, and when he heard that King Chen Liuwang was asking for peace, he knew that it was Li Yuan's intention.

The purpose was simple, the battle was won by logistics, and he was worried that the imperial court would drag its feet and that if a decision went wrong, they would be trapped in Goryeo.

Li Yuan was very clever and used this peace letter to make the emperor, who was so happy, immediately order the collection of troops, so that he could return logically.

The ministers gathered together to make a noise, and no one could make up their minds, so there was no result for a long time, but it made Emperor Yang of Sui feel a little headache.

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

Li De didn't expect the emperor to ask him what he meant by asking him about the affairs of the Sui court, maybe he just asked casually.

The eyes of the courtiers were all focused on Li De, and it was not appropriate not to say it now, although they didn't want to pay attention to it, but so many people watched, how to do it without saying anything.

He admits that he has never been a stage fright.

"In this battle, the soldiers and horses of the Sui State have the upper hand, so it is better to obtain greater benefits, is Your Majesty satisfied?" Li De's words suddenly turned into rhetorical questions.

Emperor Yang of Sui instantly understood what Li De meant, thinking that Li De was such a person, caring about interests like a businessman, thinking that this was really the case, now that the soldiers and horses of the Sui State have the upper hand, it is very inappropriate to only get this benefit.

You must know that the materials and money consumed by gathering 600,000 soldiers and horses are huge, and if you can't take the capital, he will feel a loss.

"Li De, you're right, since the other party is asking for peace, then as a state of etiquette, send an envoy first, and Lu Fulin will leave this matter to you." Emperor Yang of Sui said.

Lu Fulin instantly felt bad, visiting the belligerents, or to compete with the other party's king for interests, the more he thought about it, the more afraid he became.

"Commandment." Lu Fulin didn't have the confidence to say no.

The emperor sent a message that he had to go.

Lu Fulin also glanced 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 did Emperor Yang of Sui decide had to do with him, his purpose was to help the cheap old man.

Nothing more.

The envoy is out, the war will continue, if the talks are agreed, then I believe that soon the soldiers and horses of the Sui State will come back, and it is not good that Yuwen Chengdu and the Xiao Cavalry Guard will be stayed.

It was all his guess.
