With these special engineering robots, orders can not only be fulfilled within the specified time, but also exceeded.

In a month and a half, Princess Hongyu delivered the order. And those representatives also sent a large amount of raw ore to the Hongyu Empire.

Although both sides of the transaction deliberately blocked the news, someone still spread the news. The news came out not only by spies from various countries, but also by Princess Hongyu herself.

The reason why Princess Hongyu leaked the news is very simple. She can't let a few of these forces dominate, she must balance the combat power of these small and medium-sized forces.

Although these countries have combat robot units, they only have the right to use them, and it is impossible to make them themselves.

One more thing is that these robots need maintenance. Usual maintenance is fine, only regular maintenance is required. However, once these robots are allowed to participate in the battle, the robots may be damaged, and spare parts will be needed.

And the manufacturing technology of spare parts is also in the hands of Princess Hongyu, and if they want to maintain the robot army, they must have a good relationship with Princess Hongyu.

In this way, as long as the country that purchases combat robots will be firmly controlled by Princess Hongyu.

Many countries understand this, and they don't want to be controlled by others. But there is no way, if you don't want to be controlled, you can only not procure, but if you don't procure military power, you will distance yourself from countries that have robots.

Unless you can make it yourself, it won't be controlled by Princess Hongyu. These countries that purchase robots have all gathered a group of scientific elites to analyze the manufacturing technology of robots.

But the results are all the same, not to mention the analysis of the core technology, they can't even disassemble the core system, so what is the analysis.

However, Princess Hongyu is very worried that there is no shortage of masters in these countries, and if they analyze it, then she will lose a lot.

For this reason, she also went to Lin Yifan many times and asked him for solutions. Lin Yifan reassured her, saying that those countries couldn't be analyzed.

Although Lin Yifan told her like this, she was still a little worried in her heart. However, Lin Yifan did not comfort her, even if those countries dismantled the core system, they could not analyze it with their technology.

Just kidding, that's the god-level technology inside the crystal stone. Not to mention that these low-level civilizations are the scientific elite of the hegemonic forces, and it is impossible to analyze them in a short time.

However, there is one thing that will worry Lin Yifan, that is, those scientists who participate in scientific research. They can get the blueprint for the robot, and if these scientists are blackmailed, the manufacturing technology will be leaked.

Princess Hongyu is very smart, and she also thought of this. When the combat robot was manufactured, she built a base community near the robot manufacturing center and brought all the scientists' relatives to live here.

To be on the safe side, Princess Hongyu also sent a large number of combat robots to protect her. Now, without the order of Princess Hongyu, it is impossible for anyone to approach that base community.

The family was protected by Princess Hongyu, and these scientists had no worries. They are now working hard every day, trying to learn the technology taught by Lin Yifan.

With the simultaneous efforts of the spy and Princess Hongyu, the news of those small and medium-sized forces purchasing robots soon spread.

This incident caused another sensation in various countries, and many countries did not want to open up a gap with them militarily, so they sent representatives to the Hongyu Empire.

Princess Hongyu secretly snickered, but she still found a few representatives of the previous purchase with righteous words and asked them to give a reasonable explanation.

The delegates were dumbfounded when asked by the princess, and they didn't know how the matter could get out. However, according to the reservation of both parties, the purchaser must give Princess Hongyu a certain amount of compensation if the news is leaked.

Although this treaty is very unreasonable, but these representatives have no choice, who let them stalk and have to purchase, Princess Hongyu didn't want to sell it at first.

There is no way, the negotiated treaty is there, and they can only compensate according to the treaty. The raw ore compensated for is one-fifth of the total amount purchased, which makes these representatives feel pain again.

However, fortunately, there is also a clause in the treaty that the first batch of purchases enjoy certain privileges, that is, when the next generation of export robots comes out, they have the right of priority to purchase.

With this treaty, the hearts of those delegates were a little more balanced. At least they are in the field of robots, second only to the Hongyu Empire.

Seventy or eighty countries came to purchase at once, and those countries with weak strength also tried their best to order thousands of units.

Although a few thousand units cannot form a strong battle, they can at least protect the safety of the lord. Otherwise, if the country with robots wants to carry out assassination, those ordinary guards will not be able to resist it at all.

So many countries come to purchase together, which can make Princess Hongyu busy. On average, there are 100,000 combat robots per family, which adds up to tens of millions.

Even with the assistance of special engineering robots, this manufacturing volume is also a lot of pressure for Princess Hongyu.

Hearing the news, Lin Yifan and the others all laughed. They felt that Princess Hongyu was too capable of making trouble, and she definitely had a fight with Li Na.

Princess Hongyu is difficult to ride a tiger this time, and with such a large amount of manufacturing, she doesn't even have a little free time.

In order to be able to complete the order on time, she can be said to have exhausted all her spells. This time it was she who did it herself, and she was embarrassed to go to Lin Yifan again.

However, Lin Yifan has his own purpose, and it is impossible to let this matter tie up Princess Hongyu. This time, he took the initiative to find Princess Hongyu and gave her the intelligent program written by Tice.

With this smart program, the manufacturing speed has increased several times more. Nowadays, many manufacturing lines are no longer watched by scientists, and are all managed by intelligent systems.

"Lin Yifan, I love you to death now! Say, how can I repay you, or I will promise it by myself! ”

Princess Hongyu stared at Lin Yifan and said very excitedly.

Hearing Princess Hongyu's words, Lin Yifan and the others all opened their mouths in shock, and they couldn't say a word for a long time.

"Huh! Look at you nervous, I'm kidding you! Princess Hongyu said with a smile.

"Well, did you come to me today for something?" Lin Yifan hurriedly changed the topic.

"Oh! That's right, I'm going to announce the locations of those medium-sized bases and let them clear them, what do you think? ”

Princess Hongyu asked.

"Huh! You're such a ghost, it's a big loss for you not to be a businessman! Lin Yifan smiled and said.

"Aren't I also thinking about the Hongyu Empire! You just say it's okay, right? Princess Hongyu asked again.
