Li Tai couldn't help but be stunned when facing Du Ruhui's sudden question.

Li Tai knew very well that Du Ruhui was actually very close to the truth, but his qualifications were not enough to support him to see through this reason thoroughly.

There is no way, a person who can have such qualifications may not be born in a thousand years, and Du Ruhui is still far from it.

Li Tai took a deep breath, asked Du Ruhui, and said, "Does Du Xiang feel that the world's wealth is constant?"

Du Ruhui was slightly silent when he heard Li Tai's words, and said, "Is the wealth in the world constant?

For example, trading, exchanging goods for goods, seems to be profitable and loss, but overall, it remains unchanged!”

Li Tai nodded when he heard Du Ruhui's words, "From a trading perspective, it is indeed equivalent exchange.

Even if there is a gap, in reality, many intangible values ​​make the transaction between the two parties reach a balance.

But we are not talking about transactions, but wealth.”

"I hope to hear it carefully!" Du Ruhui looked solemn when he heard Li Tai's words.

"What does the so-called wealth mean in Du Xiang's opinion?" Li Tai did not explain, but asked another question.

Du Ruhui frowned, thought for a while, and said seriously, "Kaiyuan Tongbao, silk, satin, and gold and silver things!"

"Yeah!" Li Tai heard Du Ruhui's words and said, "In my opinion, the so-called wealth is just the food cultivated by farmers, the products produced by their own factories, and even the infrastructure obtained by labor!

As for Kaiyuan Tongbao, silk, satin, and even gold and silver, it is just a medium to me.

If I don’t have enough media in my hands, I will create some other media for the people to accept it, and then be willing to work is enough!"

"Food coupons?" Du Ruhui immediately reacted when he heard Li Tai's words.

"Yeah!" Li Tai nodded, "If you understand this problem, you should know that money itself is not important to me."

"What matters is what supports why this food coupon can be used as a replacement for money!"

Du Ruhui's face became ugly, and said,

"Did your food coupons really be issued according to the amount of food you have?!"

"Yes!" Li Tai replied without changing his expression.

I must have distributed it according to the amount of food I have in my hands, at most the proportion is about one to three.

The extra part is actually not just paying for food, but also other complicated daily necessities and various consumer products. The distribution ratio of one to three is very conservative!

However, Li Tai didn't dare to distribute too much.

After all, a perfect production base and suitable target items are not truly established.

Therefore, during the entire process of passage, although the proportion of food coupons began to gradually increase, Kaiyuan Tongbao and cloth were still very strong currencies.

Du Ruhui was relieved when he heard Li Tai's words. Du Ruhui was really afraid that Li Tai would do anything wrong, which resulted in bankruptcy of reputation.

To be honest, Du Ruhui also sweated coldly after knowing that there was such an operation.

However, Li Tai continued to say to Du Ruhui at this moment,

"As for what to support it, it is naturally the productivity of the people.

That is, the ability of the people with ability to transform nature through labor production!

The simplest example is farming. People grow food from the land through farming, which is a manifestation of productivity.”

Du Ruhui frowned when he heard Li Tai's words.

Although Li Tai has explained it as much as possible, he still said those words. If you want to explain this matter thoroughly, it is really not something that Li Tai can explain clearly.

Even Du Ruhui had vaguely grasped something, but now when he heard Li Tai's words, he was a little confused!

Li Tai looked at Du Ruhui without saying anything and couldn't help but cover his face.

I originally thought I could explain this matter clearly, but after Du Ruhui knew the principle, he had a fellow practitioner.

But save money. If these things were really easy to explain clearly, I would have become a lecturer in my previous life.

Li Tai took a deep breath and reorganized his words, "Simply put, I used the various tools I developed from the Moji and the ox produced in the grass planting program to replace the labor of the tenant farmers!

At the same time, the extra people can be put on more technical jobs.

For example, cleaning up silt and widening river channels can only allow corvee labor, and there is no way to replace oxen.

Through my reasonable scheduling resources, both things can naturally be done!

But I foreseeed these extra labor and made reasonable distributions.”

When Du Ruhui heard Li Tai's second explanation, he immediately understood the whole thing, but Du Ruhui said with a pity,

"It seems that even if you want to explain the truth that King Yan has learned, it will be very difficult to explain to me!"

When Li Tai heard Du Ruhui's words, he wanted to comfort him, but he felt it was not appropriate.

I can't help but feel that my level is indeed limited. I really can't explain a series of knowledge about productivity and production relations in a simple way!

Du Ruhui said calmly to Li Tai, "At least, the theory of King Yan can only be implemented by treating the people well.

The saint once said that water can carry a boat and can also overturn it, but the theory of King Yan is to do everything possible to follow the water and push the boat along with the water!”

"Uh... it's exactly!" Li Tai nodded naturally when he heard Du Ruhui understand this way.

Du Ruhui smiled and said, "Youzhou's canal transportation plan is implemented smoothly, and I will set off soon."

"Du Xiang worked hard and made great contributions, but thank you for your hard work!" Li Tai quickly saluted when he heard Du Ruhui's words.

Du Ruhui glanced at Li Tai and continued, "In addition, the imperial court reached an agreement with Goguryeo, and both parties opened trade ports!"

"Oh? Is it Pyongyang City?" Li Tai asked when he heard Du Ruhui's words.

"How could it be opened there!" Du Ruhui shook his head when he heard Li Tai's words,

"It is the estuary of the Han Dynasty, the Wugu River and Yalu Water.

Goguryeo built a big city there, and chose it as the trading location for Goguryeo."

Although Li Tai was completely unaware of the so-called Daxing City, Li Tai immediately understood when it came to Yalu River.

Goguryeo chose a modern location in Dandong as a trading port for exchanges with the Tang Dynasty.

Dandong is located in the center of Northeast Asia and is an important intersection between the Northeast Asia Economic Circle and the Bohai Rim and the Yellow Sea Economic Circle.

It can be said that it is a very important city in the north of the country. If China wants to ensure its influence on the Korean Peninsula region, then Dandong construction cannot be put aside. To a certain extent, it is a business card city for the Korean Peninsula.

It can only be said that Goguryeo chose such a location as an open location for both parties, which is a way to show its sincerity.

After all, this place is considered the hinterland of Goguryeo, which is full of sincerity, but at the same time, the Liaodong area is considered to be full of hills derived from the Changbai Mountains. Even if the Tang Dynasty wants to attack Goguryeo through this place, it is definitely not easy.

For Goguryeo, compared to the almost terrifying coastline, it is always easier to just guard this place.

"Will the King of Yan guess where is my Tang Dynasty's trade and trade point?" Du Ruhui said.

"Not in Tianjin?" Li Tai asked in confusion when he heard Du Ruhui's words.

"It's Tianjin, it's all your wishes!" Du Ruhui said, "In addition, the Goguryeo trade port will not open until the Goguryeo messenger returns to Goguryeo, but the Youzhou trade port will be opened first, so

Show sincerity.”

"Okay! Thank you for telling Du Xiang!" Li Tai saluted Du Ruhui and expressed his gratitude for notifying him in advance.

Du Ruhui waved his hand and said, "Build Youzhou well. This model of targeted trading between the two countries is unprecedented. I am afraid that there will be countless things you encounter in the future. I won't bother you. Watch it in Youzhou.

Just go!"

"Greatly send Du Xiang to Du." Li Tai bowed to Du Ruhui and sent Du Ruhui out of his mansion.

As Du Ruhui said, after patrolling the Grand Canal of Youzhou, Du Ruhui took Ma Zhou and continued to head towards Cangzhou.

Although Du Ruhui was in Youzhou during this period, the matter in Cangzhou was already prepared.

At this moment, Du Ruhui went to Cangzhou. It was only three months at most that this section of the canal could be cleaned up and a standard Jinkou was established. The entire "Cast Transport Plan" was officially laid from north to south.

Du Ruhui took Ma Zhou away, but Li Tai did not stop at work.

After all, after the Grand Canal was cleared, the road from Yongnu to Tianjin City was built and repaired, as well as the road from Tianjin Port to Jinkou, Li Tai had endless work to wait for these corvee labor.

However, with the arrival of May, all families of all major and small in Youzhou completed spring plowing and sowed corn.

Li Tai did not forcefully promote wheat. After all, wheat is not grown much in Youzhou now. More importantly, if they plant more wheat, then when they grow wheat in late autumn, they will use the plowing oxen.

They have a conflict!

However, as their demand for plowing oxen began to decline, Li Tai began to cultivate a large area in Tianjin.

To be honest, Tianjin is located almost on flat ground, and with the rich water resources in the territory, there is nothing when the canal has not passed here, but when the canal passes here, the land in this area is naturally highlighted.

At the same time, the students from Youzhou Agricultural University also began to graduate, although the number of this group was just a small number, only about 200 people.

When Li Tai got to the hands of about 100 people, it was enough to ask them to organize corvee workers to reclaim wasteland.

At this time, Li Tai sent a message to Lu Cai, who was far away in Chang'an, asking him to grind the wheat that had been harvested this year into wheat flour, and then send students from the Agricultural College who were willing to go north to Youzhou to deliver the wheat flour to Youzhou.

Lu Cai did not dare to neglect this matter, and replied that he would send wheat flour to Luoyang first, and then from Yongji Canal to Youzhou.

However, from Chang'an to Luoyang, the Wei River waterway can only go to Huazhou, and the remaining roads require land transportation.

During this process, unless you buy food along the way, the food consumption will be very large, with at least more than 30% of it. Please prepare for the King of Yan.
