The dragon clans have no specific concept of the "mechanics" mentioned by Roddy, so the problems are a bit scattered. Roddy is not afraid of being a physics teacher once, and said patiently: "In fact, if your speed is fast enough, the heat generated by the friction of air resistance can even ignite objects. I don't know if the dragon clan can achieve this speed, but the faster the speed, the greater the air resistance to overcome, and everything is relative."

"I can understand this way, because the faster you fly, the harder it will be to accelerate."

"Roddy, then do you think the crystal cannon can be infinitely amplified? If you make a super large gun barrel, can you blow up the target hundreds of kilometers away in one shot?"

Iscar was more interested in weapons, but Roddy nodded: "If the materials are enough, it is not a problem to make a giant cannon that can bombard thousands of miles away, but that is just theoretical data. How much material is used to make such a large crystal cannon? How much crystal energy is consumed in one shot?" Roddy said as he said to the crystal dragon next to him: "Essin, can you help me with illusion? Use illusion to simulate a sand table around the imperial city."

"no problem."

Essin raised his hand and a sand table made of phantom appeared in the center. Roddy used his spell to build a crystal cannon model. When Iscar saw its size, he immediately patted his forehead: "If this is really done, the five dragon clans will not be enough to make a few shots..."

"Yes, but there are actually many solutions for remote and even ultra-long-range strikes - if you are interested, you can participate."

Roddy's seemingly inadvertent words immediately made the eyes of the other four dragon tribes lit up.

"Ah? Can you tell us?"

"Of course, even if the demons don't invade this plane, we will be hit sooner or later!"

While raising his hand and using spells to build a rocket model, Roddy said to them: "Having ultra-long-range strike weapons, after invading the demon plane, he directly shot hundreds of shots from the demon lords. Who can withstand it? At that time, the credit for killing the demon lords will probably be remembered on you."

"How to do it? Don't keep it in a silence..."

The Black Dragon Rubens was obviously tempted, but Roddy took a stack of paper from the side: "If you want to do this, let's do it together. You are all young talents in the Dragon Clan, but I think there must be many people in the clan who are staring at your position and want to replace it? Now this project is actually worthless, but if you complete it with confidentiality, the future contribution will only belong to you."

"If you want to do it, it's best to sign a 'disclosure agreement' to confirm that it will not be leaked to others during the research."

Roddy looked up at the dragon clans in front of him, but they looked at each other and nodded: "Okay!"

While talking and laughing, he fooled the four dragon clans into joining the group. Roddy's skill did make Kardashian amazed. Akasha and Sally didn't know how to describe this - they didn't understand the principle of what Roddy said, but they watched the person they like still feel free to show off in front of the dragon clan, and the love in their eyes could no longer be concealed.

The "Disclosure Agreement" is not much, but the five dragon tribes cast spells together to confirm the effectiveness of the contract, and then everyone went to the restaurant to have a meal. At this time, Rubens, who had recently joined the group, spoke to Stica and became casual, because an agreement was not only as simple as establishing a "R&D team", but also established a "circle" and made a deeper connection between the few people.

Any ethnic group will have a different closeness and distant relationship, and is tied to the five young talents of the dragon clan. It does not need to be described in detail in the stability of the entire regime.

Although the ingredients in this meal were average, the guests and guests enjoyed it. After Iscar and others left, Kardashian, who quietly returned, yawned: "It's so tiring to cooperate with you in acting. Why did you suddenly remember to pull them into Rockets?"

"Ah? This thing is called a Rocket?"

Sally, who was sobering up with a glass of warm water next to her, turned her head curiously: "I heard you talk for a long time, and I feel like a fool, and I can't understand anything."

"Me too…"

Akasha had poor alcohol tolerance, and her little face was blushing at this time, and she looked very attractive when she leaned against the armchair. Roddy took her a cushion as a pillow, and then replied: "Actually, it's just a gimmick to be a rocket. The deeper purpose behind this is about resources."

"Resource? Do you mean something like oil?"

Kardashian has learned a lot of information on the earth and knows the general concepts of things like US dollar, oil, and gold. The current "energized crystal" is a kind of energy. In terms of concept, it is similar to "natural gas", "fossil energy", etc. If nothing unexpected happens, it will be the most common energy for all ethnic groups in the continent in the future.

"Yes, the charging crystal can help the Karen Kingdom establish energy hegemony, but the charging crystal technology will not be kept secret forever. This is a certain thing."

Roddy knew very well that the larger the organization and the more complex the personnel under his command, "leakage" became an inevitable thing. Just like a mobile phone, if a company only relies on its old capital, then the future will definitely be the end of bankruptcy - "core competitiveness" is the problem that Roddy needs to think about as a top ruling person.

"The research and development of rockets requires the support of a large number of crystal stones, and the problem of insufficient crystal energy... I can use the resources of the dragon clan to solve it."

As soon as Roddy finished speaking, Kardashian reached out and poked his head: "Okay, you even planned to get in! Tell me, what else is there to say?"

"How dare you plot against you? If you don't do this, the Kingdom of Karen will sooner or later be like Charles II. Everyone can cooperate well by talking equally. If someone falls behind, the one who is ahead will not be polite."

This was said lightly, but Sally next to her was concerned. She could only learn from the governance of the entire country. But now it seems that the word "centralization" brings not only the glory, but also the risk of walking a tightrope.

Kardashian didn't expect Roddy to think so far. She could personally like Roddy and accept everything about him, but what the five dragon clans really like was strength and interests. However, at this time, the kingdom had just been unified and it was the moment when victory was needed. Roddy had calmly begun to lay the foundation for the subsequent strategy - to be an equal person with the dragon clan, he relied on not only luck and strength.

"Divorce will be together for a long time, but it will be together for a long time... At this time, what I worry most is that 'prosperity will decline'." Roddy exhaled and looked at the night outside the window: "This country will take at least five years to recover its vitality and more than twenty years to restore its population."

"Okay, then let's recover slowly. Now we have to consider - it's time to take a shower before going to bed!"

Kardashian pulled him to the bathroom. Sally and Akasha looked at the dragon clan's eldest daughter in amazement and "snatch people". As the king, Sally I felt that she could not weaken her momentum: "Twenty years have been too long! You have to tell me what can speed up this process!"

She said as she gritted her teeth and chased after her. Akasha didn't want to wait here alone. She stamped her feet, and followed Sally with red face.

But the Kardashian in front didn't care what they were thinking, and turned around and answered Sally's question with a smile: "I know this answer - build ships, explore the sea, and colonize."

"colonial?"

Sally asked in confusion, but Kardashian did not continue to answer, and pushed Roddy into the bathroom on his own. Sally, who was standing outside the door, turned his head and looked at Akasha, who whispered: "Why... wait?"

"I am the Duke after all--oh no, I am the king now! Don't fall behind!"

She took several deep breaths, her face flushed and wanted to take a step but didn't dare. In the end, Akasha pushed her: "If you're late, let her succeed..."

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

July 20.

The Kingdom of Iversa has gradually returned to peace, but for many remote areas, they still know nothing about what happened to the Kingdom in the past two months.

The boy Suville looked at the sky bored in the shadow of the straw stack. He held a straw pole in his mouth, thinking about whether he would go to the river to catch fish in the afternoon, but before he got up, a roar in the distance made him jump up suddenly.

In his sight, several huge objects appeared one kilometer away, which seemed to be moving slowly towards this place. Suville thought it was a powerful monster at the first time, so he ran back to the village of Todd where he lived - the small village in the northeasternest of the kingdom was only more than 70 people in total. Because the terrain here is complicated and the roads connecting other villages are very difficult to walk, so until now, they don’t even know the news of the orc invasion last year.

"There is a monster! a big monster!"

Suville's notice made the small village lively. The village chief brought more than a dozen young and middle-aged men to the village with wooden sticks and iron tools in hand and looked into the distance. He was immediately scared by the "big beast" that had already approached many...

The huge figure of the road-building puppet makes the figure of humans extremely small. They may suffer casualties when dealing with a wild boar of about 100 pounds. Where can this tons of things be fought against? So the village chief immediately ordered the villagers to prepare for escape. However, the three engineers riding horses quickly relieved their panic. They not only came to inform the news that the "road" was about to be repaired, but also brought six bags of various jerky and honey as a "meeting gift".
