I hand over the Wanjie trading system to the country

"Are these made by your descendants?" Li Shimin seemed to have some ideas.

"That's right." Dean Hu nodded, "By this time, technology has been relatively advanced."

"Then, can my Tang Dynasty learn these techniques?" Li Shimin asked.

"Some technologies are fine, and some technologies still need some thresholds." Even if you copy the answers, not all of them can be copied.

"So that's the case." Li Shimin muttered to himself, "So the gap is so big!"

"Let's not talk about these." Li Shimin returned to his mind, "I don't know these things, if I want to buy them, how much will they cost?"

"A deal! It can be reached without objection from both parties."

"Many things in Datang can be traded to us, not limited to gold and silver."

"Actually, for us, the last thing we need is gold and silver, haha."

Hearing Dean Hu's words, Li Shimin secretly breathed a sigh of relief.

As long as you don't ask for money, everything else is fine.

Now Li Shimin has just succeeded to the throne, not to mention that the national treasury is not abundant at this time.

And the upcoming Weishui alliance, all kinds of natural and man-made disasters.

Li Shimin's head throbbed when he thought of it, and he wished he could split a penny in half and spend it.

"We all need cloth, silk, pens, ink, paper and inkstones, flowers and trees, pots and pans."

"If possible, we also want medicinal materials, prescriptions, and books."

"And water, river water, well water, rainwater, etc."

"It would be better if there was soil, but the soil is a bit demanding, and it can't just be dug out casually."

The researcher of the Institute of History explained all the things that need to be traded in the previous list.

"These? All okay?" Li Shimin was a little puzzled, "These things are useless!"

"That's right, there was a Tang Dynasty in the past on our side, but due to some reasons, there were some historical gaps."

“If these things could be collected, it would be very helpful for some studies of our world.”

"Okay, as everyone said, it's a transaction, both parties agree." Li Shimin smiled, "Then we will bring these things to you tomorrow."

"Then what do you need here?" Dean Hu asked.

"These convenience foods, as well as grains, are the high-yield grains you mentioned before!" Li Shimin said.

"We need to clarify with you about the grain seeds first. Our average yield per mu is 1000 kilograms. It shouldn't be that high in Datang."

"Why is this?" Li Shimin was a little anxious.

"We have pesticides, fertilizers, and various machines here." Dean Hu said, "Planting the land does not mean that the same seeds can have the same yield."

“The condition of the land, the climate and so on all matter.”

"Then pesticides, fertilizers, and organic...can you sell us some machinery?" Li Shimin asked.

Li Shimin felt that there was a gap there, so he tried to make up for it.

"This..." Dean Hu was taken aback, "I'm afraid it won't work."

"Why is this?" Li Shimin's voice became louder involuntarily, "You can say anything you need, and I will definitely find a way to find it."

"It's not for this reason, you listen to me first." Dean Hu reassured.

"Ahem, I'm sorry, I lost my temper." Li Shimin coughed twice in embarrassment.

"Pesticides and chemical fertilizers are the products of modern technology. Although they can increase production, the damage to the ecology is indelible."

"We're trying to avoid using these things as much as possible now."

"Pesticides are dangerous to a certain extent. Once ingested by mistake, it is basically impossible to save them with Datang's medical skills."

"Now let's talk about various machines. With these machines, one person can complete the work of 10 or even 100 people."

"But the fuel these machines need is not available in Datang."

Li Shimin was stunned for a while after hearing this. He had good things but couldn't use them himself. This feeling was really uncomfortable.

"Thank you, sir, for clarifying the confusion." Li Shimin smiled bitterly, "It's just my imagination."

"We have some improved farming tools, and we can give you the blueprints at that time." Dean Hu said. "It can also improve a lot of efficiency."

"Thank you sir." Li Shimin stood up and bowed.

"Be polite, be polite." Dean Hu hurriedly avoided.

"The channel will be closed in half an hour." Chuno reminded.

"Then let's hurry up and trade today's supplies first," Dean Hu said.

"Okay." Li Shimin nodded, "Then today I want some compressed biscuits and instant noodles."

Li Shimin said that he half remembered that he hadn't taken out what he paid.

Thinking of this, Li Shimin touched his body, looking for something that could be traded.

After searching for a long time, I realized that I had no money in the palace.

Seeing Li Shimin's embarrassed look, Fang Xuanling and the others quickly rummaged through themselves.

They don't need gold and silver very much, so what else can I trade now?

"Sir, do you want this book?" Wei Zheng took out a book from his arms and asked.

"Yes, yes, of course!" Papa Chu was so happy that he stepped forward and carefully took the book from Wei Zheng's hand.

It's not a very famous book, it should be a miscellaneous book that Wei Zheng used to pass the time when he was free.

"I have a jade pendant here, can you take a look at it?"

"I have a...belt here, which was bestowed upon me by His Majesty two days ago."

"My robe is made by the palace...how about giving it to you too?"

After speaking, Li Shimin took off his robe, and a group of people stared at him in a daze.

"This...you don't have to go to this level." Dean Hu was a little confused, "It's okay to replace it tomorrow."

"Then I'll find some palace-made clothes and send them to Mr. tomorrow."

Li Shimin didn't think there was anything wrong, anyway, after a while, it would be the Lizheng Palace of Empress Changsun.

"Excuse me, sir, how many compressed biscuits and instant noodles can these things be exchanged for?"

"It can be exchanged a lot." Dean Hu said and looked at several people, "but how do you move away?"

This world is not like the previous ones. Once the space is opened, you can pack as much as you want.

The system stipulates that things before the "different world" cannot be traded with each other.

But even if there is no such regulation, everyone will not give Li Shimin and others space-like things.

"I can move as much as I can." Li Shimin said, "Can I move now?"

"Yes, there are stocks in the supermarket." After speaking, Dean Hu led a few people to the entrance of the supermarket.
