The black dragon Rubens raised his hand to cast the spell, and in the blink of an eye-catching dirt launch pad was condensed with the soil on the ground, and then put Mark 4 on the launch track.

Roddy and everyone stood twenty meters on both sides and summoned the three-sided shields on the front and back to block the front. Iscar took out a mitral magic array board as big as a palm: "To be honest, we have never touched this weapon that separates from the caster before..."

"Because only in this way, you don't have to follow it and find a target."

Roddy pointed to the distant sea area: "Let's fight here, have you used six crystals this time?"

"Yeah, six."

Iscar raised the magic circle, looked at the others left and right, and then directly inputted mana, activated the energy jet magic circle inside Mark 4.

This is not the same as the principle of the "Crystal Spear". The latter simply casts all energy at one time, while Mark IV now converts energy into airflow ejected from the bottom - this is naturally the idea given by Roddy. For the dragon clan, it is not difficult to create such a magic circle. The only difficulty lies in the structure and material of the rocket. The previous failed items ended up with an explosion and disintegration due to insufficient strength.

With the harsh whistling sound, the rocket with a flash of metallic luster ejected out in the blink of an eye. After leaving the launch frame, its tail trembled violently. It seemed that the jet airflow was not very stable, but it did not change much trajectory and quickly continued to fly towards the distant sea surface. The jet airflow left a long white mist in the air. The test-firing rocket was moving forward all the way and almost flew to the end of its vision...

The four dragons didn't talk nonsense and flew directly to chase after him. Roddy sat on the coast and waited for more than ten minutes before he saw them returning with the rocket wreckage that had changed color due to high temperature friction.

"At least thirty-eight kilometers!"

"This is just the first sample made in proportion. If you use more crystals, the range is not a problem - Huh! It's really unexpected that it's so far!"

"I'll collect materials. Marco V must break through fifty... Oh no, a range of 100 kilometers!"

A group of young dragons were excited as children at this moment, gathering together for a long time to discuss, and then taking Roddy back to the Dragon Tower to continue research. Iscar was thinking about the "new weapon" that Roddy just mentioned. After everyone landed on the Dragon Tower, he asked in a low voice: "Can you reveal some news? What weapon do you want to make?"

"It's not something new. It's a crystal cannon." Roddy pointed to Iscar's strong body: "Your body strength is comparable to a city wall. I was wondering if I could develop a small crystal cannon that allows the dragon clan to carry it with me."

"What's the point? Can't we use magic to create the same effect?"

Rubens seemed to be somewhat resentful of any weapon, and Green Dragon Stica was also puzzled: "Yes, if you create a handheld crystal cannon, then the caliber and power will definitely not be as big as the ordinary crystal cannon. It is troublesome to use it. You have to carry so many shells with you, which sounds a bit useless..."

Roddy did not argue that there is indeed a lot of gap between "heat weapons" and magic at present. Judging from the results, "heat weapons" are still at a disadvantage. The crystal cannon that can threaten the dragon clan lord is huge in size and requires a truck to pull it, which is extremely inconvenient to use; while ordinary crystal cannons are too powerful and cannot even break the shield.

That being said, but Essin and Iscar both showed an expression of interest, and the Red Dragon even smoothed out: "It's not a waste of money, you have to try it in practice! Prime Minister Roddy, if you can, I'm willing to try it."

"Me too."

Seeing that they were half-joking and half-serious, Roddy nodded and chatted with a group of people for a while about Mark Five's improvement ideas before leaving the laboratory.

*******

In the early morning, the human market in Elsa Village had just opened, and a noise came from outside the village.

Pushing open the window, Nora glanced at the team entering the village and looked back: "It's the village chief who is back."

It was not common for Brody to go out for nearly a week and it was not common. Nata had already changed her clothes. After sorting out today's information, she went downstairs alone and went straight to Brody's wooden house.

On the way, Nata saw that there were already many mercenaries dressed in the village wandering back and forth. It was obviously the first time they came here, and they were curiously looking left and right. Some people seemed to want to tease the passing female elf because they didn't understand the rules, but they were scolded by the guards. Most of the mercenaries have strong tempers, so they naturally have to talk a little when they encounter such things. However, after the guard captain wearing armor came over, the mercenaries immediately stopped and accepted the mistake and left.

Because the captain of the guard had a huge wolf head emblem on his chest, and there were two unique epaulettes on his shoulders... Those who know how to be aware of it would know that he was a formal non-commissioned officer belonging to the Iversta Infantry Division.

Other soldiers can look down on them, but the Everta Infantry Division, which swept across the kingdom, must not be provoked. Nata saw the mercenaries swallowing their anger, but could understand their inner fear. After all, all the guards in the village are veterans who are specially rotated, each of them is full of murderous aura and serious.

The soldiers did not know Nata's identity, and after resolving the dispute, they returned to their posts and continued to stand. She knocked on the door in front of Brody's wooden house, but then saw Brody coming to the door to greet herself: "Huh... This is the best news in recent months, Nata, welcome you home!"

Nata was a little moved, but all she could do was bent down to salute the old village chief.

"I've asked a lot of news about you before. At first, you said you went to Elson City, but then I didn't hear from you. I thought something happened. Thank God, it's great to see you safe."

Village Chief Brody looked much richer than two years ago. His clothes were no longer torn, but a fox fur robe with exquisite workmanship. The fire in the house was burning brightly, warmly isolated from the cold outside.

Although he is the village chief, Brody has not yet made a bunch of servants to serve him like a human noble. He took off the boiled kettle. Seeing this, Nata hurried forward to help pour water. Such behavior also made Brody smile with relief: "Is there any new arrangements for the Prime Minister when I come back this time?"

"There are not many things, I'm going to come back for a holiday."

Nata would not disclose her identity and action plan to anyone outside the organization. She talked about what she had experienced outside in the past two years like a wanderer returning home. The outside world is ultimately more exciting than the small Elsa Village. When the village chief Brody heard Nata say a few things, he was envious and sighed: "Oh... I can only stick to a few villages in my life toss."

"I just heard you... I didn't seem to have a smooth conversation with Village Chief Bati?"

"It's not just a bad time, I almost started a fight... Alas--Batty was also a very reasonable person back then, why is he so paranoid now?"

Brody held the water cup and sighed: "All villages have some contacts every year. If that village encounters disaster, everyone can help, and they have to survive the winter."

He took a few sips and sighed: "This year, the village of Bati is in bad condition. At first I thought it was attacked by the beast group, but when I went there, I found that the hunting team suffered heavy losses. This situation must be difficult for winter. But after getting him so much food, this guy insisted on betraying the wood elf."

Nata had learned about these things from Hugo, and she asked in a low voice: "Pursuant to be too envious of Village Chief Bati, which caused her heart to be unbalanced, right?"

"Who knows, but I think he may feel that he is stronger and more confident than me."

Brudy said and patted his belly. Two years ago, he was so skinny that he had some fat on his belly. "I'm busy with these trade affairs all day long and don't bother to study those spells. Barty probably thinks I'm forgetting my roots and speaks very badly."

"Now we have the army guarding of the Karen Kingdom. If anything really happens, Pal's leader can send troops to help immediately. It is really not worth learning those spells. After all, war really breaks out, and you don't need to go to the front line."
