The difference is that all this money has gone into the pockets of the eldest grandson family, and Li Shimin must have earned more.

"His Royal Highness King Qin, have you read the newspapers in Youzhou?"

"Mowgli, what's wrong with you?"

"Your Highness, the merchants of Youzhou are selling a kind of guard food called compressed biscuits, it is said that one piece can support a day's rations, according to the news, several forces have purchased it, and it is a rare dry food for foreign wars."

Li Shimin began to pay attention to it, you must know that some of the combat effectiveness of the vanguard is really related to their dry food, once there are these compressed biscuits, they can save a lot of time in the process of moving, not to mention, it can also greatly reduce the speed of transporting grain and grass.

The most important point is that these compressed dry rations are easy to carry, and a person will not be able to carry ten days of dry food more than carrying a weapon.

Especially when the cavalry travels, it can be carried with horses in a centralized manner, which can fully support the consumption of a month, and if the horses are enough, it is also possible to consume more days.

Of course, the premise is that the soldiers can insist on eating compressed biscuits for a long time, which is really nothing in Li Shimin's opinion.

On the battlefield, if there is no food, everything will be eaten, not to mention that compressed biscuits are made purely from grain.

"Mowgli, if we buy some, will it cause dissatisfaction among the courtiers." Li Shimin asked.

The purchase of compressed biscuits from Youzhou cannot be hidden, after all, these things are to be distributed to the soldiers.

"Your Highness, I think it's better to explain the matter to Your Majesty, maybe the courtiers already know about this matter, with these dry foods, you can increase your combat power, I believe Your Majesty can understand."

Zhang Su Wuji meant to directly say the pros and cons, Li Yuan was still able to listen to the persuasion, and besides, they were buying products from Youzhou merchants and would not involve conflicts between the two forces.

Don't forget that many forces have bought it, not only compressed biscuits that can be stored and carried for a long time, but these compressed biscuits are all food.

Although Chang'an and Luoyang have harvested a lot of grain in the autumn harvest, it is still not enough compared to consumption, if you can buy more compressed biscuits, if there is a famine, it can also make people full.

After listening to the words of the eldest grandson Wuji, he did not hesitate, knowing that the Li family's soldiers and horses would continue to produce and occupy more places in the future, and it was necessary to reserve dry food, and now that he had this good opportunity, he could not miss it.

So Li Shimin immediately entered the palace to face the saint.

"Father, there is a private compressed dry food workshop in Youzhou newspaper that is selling compressed biscuits, one piece can top the last day's rations, and this ration has been purchased by several forces, and the sons think that we can purchase some for reserves."

"Don't the merchants in Youzhou take care of these things?" Li Yuan has already read Youzhou newspapers, don't look at his superficial demarcation with Youzhou forces, but he pays no less attention to Youzhou than others.

"Compressed biscuits can be purchased, but not too much, these things are not better than food, even if the storage time is long, there is still a time limit, if we can get the technology to produce compressed biscuits, we can process it ourselves."

Li Yuan said that these were not said casually, obviously just asking him to find a way.

Li Shimin thinks that this is a good way, but the processing of compressed biscuits requires food, and if the grain reserve cannot be solved, it will not be able to fundamentally solve the problem.

After returning from the palace, King Qin's mansion immediately summoned a meeting of his advisers.

"Father means that he wants to buy equipment for the production of compressed biscuits."

The eldest grandson Wuji knew very well that this matter was not easy to do, and the merchants who could buy the equipment were all businessmen from Youzhou.

Besides, if it were him, he wouldn't sell the equipment to anyone else. Let's do it

"If Your Highness wants to do this, I'm afraid you have to have direct contact with Youzhou, as far as I know, the equipment purchased by merchants in Youzhou needs to pay technical franchise fees, and it is impossible to get equipment through merchants." Fang Xuanling said.

These people have paid attention to the newspapers in Youzhou, and the news of encouraging invention and creation before is not limited to Youzhou but also includes the whole world.

"It seems that someone is going to be sent to Youzhou to talk about cooperation, who will go?" Li Shimin asked.

Fang Xuanling and Du Ruhui all looked at the eldest grandson Wuji, not to mention how much resentment there was in the eldest grandson Wuji at this time.

"Is Mowgli willing to make this trip?" Li Shimin asked.

The eldest grandson Wuji was a little timid, after all, the forces on both sides were enemies, especially the vanguard snatched Penglai City from his hands, if he wanted to be honest, he didn't want to go, but when he saw everyone's eyes, he knew that he had to go.

"Your Highness trusts me to do my best."

The eldest grandson Wuji felt bitter in his heart, he really didn't want to go, what if he didn't come back.

But there was no room for him to turn back.

A few days later, the eldest grandson went to Youzhou in the name of the envoy of Chang'an.

Li Shimin was reluctant to let the eldest grandson Wuji go to death, so he asked for the title of an envoy for him before leaving, which can be somewhat insured, but it is not completely able to guarantee that the people of Youzhou will do anything bad.

Li Shimin had no choice, and completing the task given by Li Yuan was the most important thing.

The eldest grandson Wuji was worried all the way, he had been thinking about what kind of treatment he would face in Youzhou, and he was ready not to come back.

The only thing he could use to save his life was a letter handed over to him by Li Shimin, which Li Shimin wrote to Li Xiuning asking him to send the letter to the Governor's Mansion whenever he encountered danger.

The envoy of Chang'an visited Youzhou, and when the eldest grandson Wuji was about to arrive in Youzhou, he sent a fast horse to deliver a letter, and he wanted to report whether the other party allowed him to visit, if the situation was not for him, there was still a possibility of escape.

When the spies who reported the news came back, Changsun Wuji's convoy was already approaching Youzhou City, and it was not the first time he came to know that Youzhou had no concept of a city.

From the boundary monument on the side of the road, you know that you have already stepped into the boundary of Youzhou in front of you.

After the city guard office got the news, a special person immediately reported the news to Li De, don't worry, the matter of visiting Youzhou is a major matter, and it must be instructed by Li De.

"The eldest grandson Wuji, ordered to go down and receive them according to the corresponding etiquette."

Then the guard of honor of the vanguard was dispatched, and it was a convoy of 200 soldiers wearing bright armor to escort the messenger to the castle guard.

Because no one watched the special road when he walked, Changsun Wuji's team was received with a high standard, and in the eyes of Changsun Wuji, it was a high standard.

The last time I visited Youzhou, it was also this kind of battle.

Immediately after arriving at the castle guard's house, a receptionist came to receive them.

The eldest grandson Wuji was welcomed to the reception room of the City Shou Mansion, and then the City Shou Mansion platoon photographed the representatives of the heads of various departments coming over.

After some introduction, Changsun Wuji had a number in his heart, and the people present were all department representatives, and he knew about them, and there was no one at the rank of captain.
