Xu Zheng was also thinking about what kind of price would be more reasonable to sell the second batch of textbooks, but after thinking about it for a while, he found that in addition to gold coins, the kingdom really didn't have anything that could tempt him, and even gold coins were just Lilith was more interested in, and Xu Zheng felt that with his current state of life, whether it was gold coins or RMB, there was not much to pursue.

This is not the time to open a small online store two years ago to sell ship girls, at that time, Xu Zheng will see one hundred and eighty yuan in his eyes, and if he sells more ship girls, he and his daughter will be able to eat more meat, how can it be that at this time, there will be no material pursuit.

Just those industries that dawn breaks on the earth and lays out, what brand of dried fish can't afford to buy?

Listening to the meaning of Augustine's words, it was obvious that the kingdom was determined to obtain the follow-up primary school textbooks, and was even willing to pay a price far beyond Xu Zheng's previous expectations, but Xu Zheng's bland reaction greatly disappointed His Majesty the King......

If we could see more books from the other side of the earth, perhaps His Majesty would understand what it means to "have no desire, then be strong".

"You're talking! What do you want! ”

After Augustine finished speaking eagerly, Xu Zheng thought seriously for a while but shook his head, looking at Xu Zheng's appearance of "not looking down on the slightest property of the kingdom", Augustine said madly: "Wealth, food, and even the magical knowledge and martial arts knowledge possessed by some other kingdoms can be the object of this transaction!" ”

Xu Zheng could also feel Augustine's eagerness to trade, but didn't he want gold coins if he wanted money? According to the selling price of the royal auction house, no matter how rich the kingdom is, it is difficult to bear such a large expenditure, Xu Zheng feels that although the follow-up "primary school textbooks" do not have much need to keep secrets, there is no reason to sell the textbooks of "fourth to sixth grade" cheaper than those of "first to third grade", right?

Even on the other side of the Earth...... Tuition fees for elementary school students are rising year after year!

As for the food, Xu Zheng has always had great expectations for Turgaon's research, with the combination of natural magic and earth's agricultural technology, sweet potatoes, white potatoes and potatoes can be grown on the other side of hell, and when these agricultural technologies are perfected, when they are popularized in large quantities in the two worlds, the grain traded back from the kingdom will definitely have to be smashed in their own hands!

As for the knowledge of magic and martial arts, not to mention, there are still two hundred high-level textbooks on the kingdom's side that have not yet been paid, and when the Huaxia military studies and understands the martial arts materials at hand, they don't know that they will go to the Year of the Monkey! Besides, what needs to be popularized on the military side is nothing more than some targeted training and strong skills, and in a world dominated by thermal weapons, the importance of individual force is relatively weak, so 300 sets of martial arts teaching materials are completely enough to improve the individual quality of the soldiers on the military side to the point of flying......

The PLA fighters give people the impression of being majestic and uniform, and they can't always have a set of martial arts textbooks in their hands, and what monkey boxing, tiger boxing, and five elements boxing are all in a wave when they are trained to exercise, right? This is not at all in line with the discipline of the troops......

In terms of magic, it is a unique skill in the world of miracles, and with the special situation of earthlings, it makes little sense to pursue ethereal magic.

Seeing that Xu Zheng was silent, Augustine frowned and said, "Don't you really have anything you want?" ”

"Dad, ...... over here"

Xu Zheng, who was still thinking about what to change, was thinking about it, and Linglong's voice sounded, Augustine glanced at Linglong, looked at Linglong hopefully, and said: "Little princess, but it doesn't matter, if you have anything you need, you can also add it to this transaction!" ”

"I think you can look at things from a different perspective." Linglong hesitated for a moment when she heard this, and felt that there was no need to avoid Augustine in her heart, and said to her father with a smile: "Since we don't have any kingdom specialties that we urgently need for the time being, it will definitely be difficult for the two sides to reach a deal, and if the buyer's market and the seller's market cannot be unified, it will be impossible to satisfy both sides of the transaction......"

After Linglong finished speaking, Augustine looked at the little girl who was less than four years old in front of him blankly, and was stunned for a while before saying to Xu Zheng: "I said Prince Xu Zheng...... Why don't you stay in the royal capital for a little longer? There are still a lot of 'young talents' in the royal capital...... Let's see if there is any possibility of marriage between the two of us? ”

Xu Zheng glanced at Augustine with a smile and said: "It's still okay to forget this matter, these things are all said by Linglong herself, besides, I think that those so-called 'young talents of the royal capital' you call can't wait for our daughters to grow up......"

After speaking, Xu Zheng also glanced at his daughter quite funny, obviously the shrewdness of the girl has aroused the strong interest of His Majesty the King.

Linglong ignored Augustine's suggestion, and continued to say to the two: "Since it is difficult to reach a deal, then we might as well change the deal to cooperation, and use the remaining teaching materials in our hands as bargaining chips to carry out closer cooperation with the kingdom, for example, if the kingdom uses the knowledge from our hometown to make new daily necessities, weapons and even some other items, it will be good to pay our corresponding 'patent fees' according to the amount of knowledge used......"

After Augustine listened to Linglong's suggestion, he wondered whether the plan proposed by Her Royal Highness the little princess was feasible, but Xu Zheng gasped, and secretly said in his heart that the girl was really ruthless enough, and even the trick of "patent barriers" was introduced!

There are not too many "patent" restrictions on technology on the kingdom's side now, just like the kingdom has also imitated canned food and biscuit instant noodles on the other side of the earth before, and the key point of Linglong's suggestion is that if the kingdom uses the earth's technology again in the future, then Xu Zheng and they will have the opportunity to charge the corresponding fees......

And not only that, but even the goods made by the Kingdom's Handicraft Association and the Academy of Magic, which combined the Kingdom's own craftsmanship and earth knowledge, also had to pay money to the Hell side as the "use fee" of this knowledge.

Compared with trading a set of textbooks with the kingdom to get a large amount of gold coins, Linglong's suggestion can use the human kingdom as an "ATM" for Xu Zheng's family, it has only been a month or two, and Chinese culture and earth science have become popular at the top of the kingdom, Xu Zheng can imagine how much earth culture will be affected by the kingdom in the near future......

Augustine pondered for a while, and felt that Linglong's proposal was still quite "kind", so he quickly moved his gaze to Xu Zheng and said: "I don't have any opinions here, I wonder if Prince Xu Zheng agrees with the little princess's suggestion on 'patent fees'?" ”
