Li De actually meant this, originally the last thing that the soldiers and horses of the Sui State could not fight was a war of attrition, because although the Sui State had enough materials, long-distance transportation would inevitably delay time, and many materials could delay the march or starve to death if they arrived late.

But this problem is not a problem at all for Bingcheng.

As long as the soldiers and horses of the Sui State landed by boat to establish a stronghold, and then transported it together with the soldiers, horses and supplies, it was enough to meet their needs for landing operations.

And the transportation does not necessarily need food, the compressed biscuits produced by the Bingcheng Food Workshop can meet this requirement, and it is completely possible for each person to carry twenty days' rations and then transport all the troops.

There was no problem in dispatching the ships of the Sui State to transport 18,000 people at a time.

Li De was silently calculating that according to the ships they had prepared before, they could increase the transportation capacity of several thousand people, and if they supported the grain and grass consumption of 50,000 people, they would need to use their small boats to transport them alone for at least a month.

If it is replaced with compressed biscuits, as long as the people of the Sui State can stand on their feet after logging in, then there is no problem, a large number of materials can be transported with the big ships of the Sui State, and a single load can supply the consumption of tens of thousands of people.

"Dadu Governor, but are the soldiers and horses of the Sui State really reliable?" Luo Song asked.

They were worried that they would fail like the first two times, and they knew a lot about the soldiers of the battle vanguard in northern Liao, because they were here now, and it was inevitable that they would not mention it.

At that time, when it was mentioned, it was discussed by several people behind people's backs, and it was not a big deal for this situation to reach the ears of Hebida and other lieutenants after it was discovered, but if it was not properly guided, I was afraid that it would end up in the shadow of defeat.

Although the battle was not fought by their vanguards, after all, they are here now, it is a lie to say that they are not worried, but everyone has fear in their hearts, and they should be more careful when whispering together.

It's not good to say much about this kind of thing, after all, everyone has their own ideas, and it's not like you don't want them if you don't let them think about it.

So He Bida told Li De about the situation, and in the end, all the battles in northern Liaobei were formulated into an atlas of the art of war, and the readers copied many copies for the soldiers to watch and study.

And also advocate the form of "class meeting" to speak freely.

They are very clear about the soldiers and horses of the Sui State, and their combat effectiveness is this, but in the face of the Goryeo people, they are completely weak, like a spell.

Luo Song didn't just bring this up for himself, the two defeats of the Sui soldiers and horses were very disappointing.

"Breaking the cauldron and fighting against the water, do you think they can still survive if they don't use their death force?" Li Dedao.

The battle against the water, the words are direct and clear, there is the sea behind them, they can't do it if they want to, as long as they can hold on to the ferry, then there is support, there are materials, this is not difficult to choose at all.

"Let the elite of the Sui State land by ship first, so that the combat effectiveness can be guaranteed and there is the strength to delay time." Li Jing said suddenly.

"That's right." Li Dedao.

A few days later, Emperor Yang of Sui sent a delegation to negotiate the matter of cooperation.

Li De felt that although this Emperor Yang of Sui was a little confused, many things were still very good, and being able to send an envoy over to discuss so quickly showed the emperor's mood towards the three battles for Goryeo.

"The governor of the capital, the old minister is Honglu Siqing, Lu Fulin, I have admired the demeanor of the governor for a long time, and it is really a blessing to see it today." Lu Fulin smiled politely.

The smiling face is head-on, as the saying goes, don't hit the smiling face person, the leader of the negotiators is so approachable, easy-going and polite, if he has a straight face or says something that is not rude, it will be too out of tune and lose his morality.

Li Dexin said that these Wenchen really didn't give it for nothing, they were all officialdom fritters, and they were very slippery.

"Let's talk about His Majesty's troops." Li Dedao.

Lu Fulin was observing Li De all the time, and they had long been accustomed to observing words and feelings, but it was the first time they had seen it so directly.

"Grand Governor, Your Majesty means that you want to garrison troops in the military city, and I hope that this Metropolitan Governor can make it convenient." Lu Fulin Road.

Li De looked at the people who came from these missions, not only Honglu Temple, but also Lu Fulin and others who presided over the meeting, but in fact, the people who really wanted to discuss were several ministers of the Ministry of War.

They are the key to negotiating, after all, when it comes to war, Honglu Siqing is not good at it.

"I'm afraid not." Li De said lightly.

Lu Fulin was anxious to defend himself, but Li De stretched out his hand and directly interrupted what the other party was about to say, and continued: "I refused not because I was worried about the safety of the military city, but there was no place near the military city, according to my wishes, part of the soldiers and horses could be placed in the outpost city, and the other part could be on the coast." ”

"Why?" Lu Fulin wondered.

"I don't mean anything else, but the next words involve military affairs, I don't know if I want to talk to you?" Li De asked.

Lu Fulin hesitated, and when he spoke, he was the one who led the envoy group to preside over the meeting, and the specific matters to be discussed really had to be carried out by professional people.

If Li De directly agreed to the conditions he proposed, there would be nothing else to do, but as soon as he said a word, he couldn't pick up the words, and he could only say that the outcome of this negotiation might not be as smooth as they expected.

"I'm Liu Xuanli, the squire of the military department, and the governor of the capital has suggestions, but it doesn't hurt to talk about it."

Li Dexian looked at the person who came, he was middle-aged, he was very shrewd and capable, and he could see from his figure that although he was a civil servant, his body and bones from martial arts could not deceive people, and if he wore armor and took a blade, he would definitely be a general.

Emperor Yang of Sui's subordinates are not all wine bags and rice bags, most of them are capable ministers of governing the country, but maybe their talents have not been brought into play, after all, Emperor Yang of Sui's reign is a bit short.

His attack decree can be said to have directly suppressed the exploits of many capable ministers with the reputation of the emperor.

Although this Liu Xuanli has not heard of it, he feels that there is something in his words and deeds, and since he is really able to speak, Li De does not hide it.

"Liu Shilang, the Pontus Governor arranged this way for you to attack Goryeo." Li De said lightly.

"Governor, please." Liu Xuanli continued.

"Then there is something to say, the plan of the Pontus Governor is like this, the 300,000 soldiers and horses you gathered are divided into 30,000 troops to garrison the outpost city, 200,000 are stationed on the beach, and the remaining 50,000 are used as baggage soldiers, the plan is like this, the elite will land by boat, and our vanguard will be responsible for the transportation of materials......"

Li De said the plan, which simply means that the soldiers and horses of the Sui State will first divide their troops to the outpost city to help build it, and the rest of the people will prepare for the landing battle, and the remaining 50,000 people will be responsible for the transportation of materials.
