The dragons don't have a specific concept of what Roddy calls "mechanics", so the questions are somewhat fragmented. Luo Di is not afraid to be a physics teacher, and said patiently: "In fact, if you are fast enough, the heat generated by the friction of air resistance can even ignite objects." I don't know if the dragons will be able to reach this speed, but the faster the speed, the more air resistance will have to be overcome, and everything is relative. ”

"I can understand that way, because the faster you fly, the harder it is to accelerate. ”

"Roddy, then you said that the spar cannon can be infinitely magnified, if it is made into a super large barrel, can it blow up the target hundreds of kilometers away with one shot?"

Iskar was more interested in weapons, but Roddy nodded: "If the materials are enough, it is not a problem to make a giant cannon that bombards thousands of miles away, but that is only theoretical data." How much does it cost to build such a big spar cannon, and how much spar energy does it cost to make a cannon?" said Roddy as he said to the crystal dragon next to him, "Essien, can you do me a favor, use illusion to simulate a sand table around the imperial city." ”

"No problem. ”

As soon as Essien raised his hand, a sand table composed of phantoms appeared in the center, and Roddy himself used spells to build a model of a spar cannon, Iskar looked at its size, and immediately patted his head: "If you really make this, the five dragons will not be able to take out a few shots with their family foundations..."

"yes, but there are many solutions to long-range and even ultra-long-range strikes – if you're interested, you can get involved. ”

Luo Di's seemingly casual words suddenly made the eyes of the other four dragons light up.

"Huh, can you talk to us?"

"Of course we can, even if the demons don't invade this plane, we will have to fight it sooner or later!"

Luo Di raised his hand to build a model of the rocket with spells, and said to them: "With ultra-long-range strike weapons, after invading the demon plane, directly follow those demon lords for hundreds of rounds, who of them can bear it? ”

"How? Don't sell it..."

Black Dragon Rubens was obviously moved by what he said, but Roddy took a stack of papers from the side: "This matter... If you want to do it, let's do it together. You're all young talents in the Dragons, but I think there must be a lot of people in the clan who are eyeing your place and want to take your place, right? ”

"If you want to do it, it's best if we sign a 'non-disclosure agreement' to confirm that we won't disclose it to anyone else during the research process. ”

Luo Di looked up at the dragons in front of him, but they all looked at each other and nodded: "Okay!"

Talking and laughing, the four dragons were fooled, and Roddy's skill really amazed Kardashian's heart. Akasha and Sally didn't know how to describe it - they didn't understand the principle of what Roddy was talking about, but seeing the person they liked still swaying freely in front of the dragons, the love in their eyes could not be hidden.

The "non-disclosure agreement" was not very much, but the five dragons cast a spell together to confirm the validity of the contract, and then everyone went to the restaurant for dinner - at this time, Rubens, who had recently joined the group, spoke casually with Stica, because an agreement was not only about the establishment of a "research and development team", but also the establishment of a "circle" and a deeper connection between the several people.

There will be a difference between relatives and aliens in any race, and the combination of the five current young talents of the dragon clan does not need to be repeated in terms of the stability of the entire regime.

Although the ingredients of this meal are average, the guests and hosts enjoyed it. After Iskar and the others left, Kardashian, who returned quietly, yawned: "It's really tiring to act with you, why did you suddenly remember to drag them to make rockets?"

"Huh? This thing is called a rocket?"

Sally, who was holding a glass of warm water next to her, turned her head curiously: "I've listened to you for a long time, and I feel like a fool and can't understand anything." ”

"Me too..."

The amount of Akasha was poor, and the little blushing at this time was very tempting, and the appearance of reclining in the armchair was very tempting. Roddy brought her a cushion to make a pillow, and helped the little priest to lie down before replying: "Actually, making rockets is just a gimmick, and the more far-reaching purpose behind this is about resources." ”

"Resources, you mean oil or something?"

Kardashian has learned a lot about the planet, and knows the general concept of things like the dollar, oil, and gold. The current "charging spar" is a kind of energy, conceptually speaking, similar to "natural gas", "fossil energy", etc., if nothing else, it will be the most common energy source for all ethnic groups in the entire continent in the future.

"That's right, the Charged Hedron can help the Karen Kingdom establish energy supremacy, but the technology of the Charged Hedron will not be kept secret forever, this is a certain thing. ”

Luo Di knows very well that the larger the organization and the more complex the personnel, the "leakage" will become an inevitable thing. Just like a mobile phone, if a company only eats its old roots, then the future will definitely end up in bankruptcy and bankruptcy - "core competitiveness" is the problem that Roddy needs to think about as a top ruler.

"The development of rockets requires the support of a large number of spars, and the problem of insufficient energy of spars... I can solve it with the help of the resources of the dragon family. ”

As soon as Roddy finished speaking, Kardashian reached out and poked his head: "Okay, you even calculated me!

"How dare you calculate you, if you don't do this, sooner or later the Karen Kingdom will fall into the hands of Charles II, everyone can cooperate well by talking on an equal footing, if someone is behind, the one who walks in front will not be polite. ”

This was said lightly, but Sally next to her was interested. For the governance of the entire country, she can only learn from the previous lords. But now it seems that the word "centralization" brings not only scenery, but also a tightrope-like risk.

Kardashian didn't expect Roddy to think so far. She can personally like Luo Di and accept everything from him, but what the five dragon clans really value is strength and interests after all. However, at this time, the kingdom had just been unified, and it was time to celebrate the victory, but Roddy had already calmly begun to pave the way for the follow-up strategy - to become an equal to the dragon clan, he relied on more than just luck and strength.

"If you divide for a long time, you will be together, but if you are together for a long time, you will also be divided... At this time, my biggest concern is that 'prosperity must decline'. Roddy exhaled and looked out the window at the night: "It will take at least five years for this country to recover, and more than twenty years for its population to recover. ”

"Okay, let's recover slowly, now we have to think about it - it's time to take a shower before going to bed!"

Kardashian dragged him to the bathroom, Sally and Akasha looked at the dragon lady in amazement, and Sally I, as the king, felt that she couldn't weaken her momentum: "Twenty years is too long! You have to tell me if there is any way to speed up this process!"

She gritted her teeth and chased after her, and Akasha didn't want to wait here alone, so she stomped her foot and followed Sally with a red face.

Kardashian in front didn't care what they thought, and looked back to answer Sally's question with a smile: "I know the answer - shipbuilding, exploring the sea, colonizing." ”

"Colonization?"

Sally asked back suspiciously, but Kardashian didn't continue to answer, and pushed Roddy into the bathroom by herself, while Sally, who was standing outside the door, turned her head to look at Akasha, who whispered, "Or... Wait?"

"I'm a duke—oh no, I'm a king now!

She took several deep breaths, her face flushed and she wanted to take a step but didn't dare - in the end, it was Akasha who pushed her: "It's too late, and she'll get her way..."

So Roddy took this bath for nearly three hours...

July 20th.

The kingdom of Evta has gradually returned to peace, but for many remote areas, they still don't know what has happened in the kingdom for the past two months.

The young man Sowel looked boredly at the sky in the shadow of the straw stack, and with a straw stalk in his mouth, he was wondering whether to go to the river to fish in the afternoon, but before he could get up, a distant roar made him jump violently.

In the field of vision, several large objects appeared a kilometer away, appearing to be moving slowly towards it. Sowel immediately thought it was some powerful beast, so he ran back to the village of Todd, where he lived—there were only more than seventy people in the small village on the northeastern edge of the kingdom, and because of the complicated terrain and undulating roads, the roads connecting other villages were very difficult, so until now, they didn't even know the news of the orc invasion last year.

"There's a monster!

Suvir's report made the small village suddenly lively, and the village chief came to the head of the village with more than a dozen young men holding wooden sticks and iron tools to look into the distance, and was immediately frightened by the "giant beast" that had already approached a lot......

The huge size of the road-building puppet makes the human figure incomparably smaller. They may have casualties when dealing with a wild boar of about 100 catties on weekdays, and where can they compete with this ton of stuff at the moment? So the village chief immediately ordered the villagers to prepare for fleeing, but the three sappers who came on horseback quickly relieved their panic, and they not only came to inform them of the news that the "road" was about to be repaired, but also brought six large bags of all kinds of dried meat and honey as a "meeting gift."

Suvier was chronically malnourished, and although he was seventeen years old this year, he looked thin like a thirteen or fourteen-year-old child. He smelled the meat in his pocket and swallowed involuntarily. But the three sappers not only brought food, but their armor and straddled scimitars silently intimidated the villagers like Sowel.
