There is a rockery behind the patriarch's house, and in a place where the rockery is tall and dense, there is a hidden passage that is very well hidden. Zhao Yan followed the patriarch into the dark passage, leading to the basement of this Tababa village.

The ground is not deep, and after walking dozens of steps, I came to a bronze door, and the patriarch said a stack of spells, and the bronze door was automatically opened.

The space inside the bronze door was very small, which somewhat disappointed Zhao Yan, but when the patriarch turned on the light in the secret room, Zhao Yan was still somewhat excited.

Overall, there are not many treasures, but there are also a lot.

Zhao Yan was attracted by the green staff inserted in the middle and innermost part of the secret room at first sight, and asked, "Patriarch Grandpa, the goblin clan is not good at forging, and this staff is also our treasure?"

Looking at this staff, the patriarch's face suddenly calmed down, and he lowered his head slightly, looking extremely pious. "This is the incarnation of our Great Mother Goddess, the scepter of the Goblin Virgin, her soul went to heaven, but this staff she used has become the most important treasure of our goblin clan. ”

Zhao Yan walked towards the staff.

No......

The patriarch shouted: "Yan, don't touch it, this staff is not allowed to be touched, including me......"

Zhao Yan was a little unhappy, he had become a patriarch and still had these rules. However, he also immediately dispelled the idea that had just been cultivated in his heart. I'm a fire mage, so it's useless to ask for this earth-based staff.

Looking around, the patriarch introduced these treasures to Zhao Yan one by one.

In fact, Zhao Yan asked the patriarch to bring it here not to covet treasures or anything, but to find out if there were any materials that could be used for his own research and invention in the goblin treasure, and then look at the previous enchanted products of the goblin clan to get some inspiration.

"What is this?" Zhao Yan pointed to a long earthy yellow object.

The patriarch took a look at it and said, "This is the earth snake that the best mechanic of the goblin clan studied many years ago. ”

"Earth snake?" Zhao Yan asked.

"Yes. The patriarch nodded, "That's a great mechanic, it's just that many of his inventions have been plundered by humans and lost, and this earth snake is his original big idea." ”

"Could it be that he made this earth snake for use in battle?"

"It's not just about fighting, it's also about being a means of transport!"

Zhao Yan's eyes widened, and he looked at the earth snake fixedly, and suddenly felt a strong respect for the dead goblin mechanic.

This guy's thinking is really avant-garde!You know, what I'm working on right now is for goblins' operations, but it seems a little insignificant compared to the sheer size of the Earth Serpent's project.

Zhao Yan nodded, he gained a lot.

Looking around, Zhao Yan's eyes lit up, and he hurriedly pointed to the place he saw, and said, "Patriarch Grandpa, that's the demon core?"

The patriarch followed Zhao Yan's gaze and grabbed the three demon cores on the table in his hands, and Zhao Yan found that one of the demon cores was even smaller than the moment he hit it.

Didn't Copus say that the smaller the core, the better!

The patriarch said, "Yes, it's the demon core, do you need it?"

"Of course!" Zhao Yan said with a smile: "Patriarch, the goblin engine can only be driven by a magic core! Without a magic core, our goblin battery can't run!"

The patriarch's green eyes sparkled, and he glanced at the demon core in his palm, then handed it to Zhao Yan and said, "This is a gem-level demon core and two essence-level demon cores." It's going to be great to make something for you. ”

"Gem-level?fine-grade?" Zhao Yan didn't understand.

The patriarch was a little surprised, and muttered to explain: "The demon core is a substance that can only be obtained after killing king-level and god-level demonic beasts, and the more advanced the demonic beast that falls out after death, the better, so the demonic core is roughly divided into five levels: general, fine, gem, god, and holy." The general-level ones are the most ordinary, and they should be easy to buy in the town, and the god-level and saint-level magic cores are treasures, usually these two levels of magic cores are enough to exchange for absolute gems with merchants. And I'm afraid these two demon cores can only be dropped by killing god-level demonic beasts like dragons!"

After a pause, the patriarch said again: "Basically, the essence-level demon core is very rare, so our goblin clan will treat it as a treasure." ”

The fine-level magic core is very rare, then this gem-level magic core, Zhao Yan holds it in his hand, and he can't put it down.

"Patriarch Grandpa, I have a general understanding, let's go back first!"

"Yes, good. Seeing Zhao Yan's excited face, the patriarch stroked his beard suspiciously.

Holding the treasure like a magic core back home, Zhao Yan immediately put all his mind into studying, according to the comparison of the size of the magic core, Zhao Yan knew that the magic core that he judged was a general-level magic core. Coupled with the three demon cores that came from the patriarch, there are now a total of four in Zhao Yan's hands.

One gem, two fine, and one general.

Although the patriarch said that the general-level magic core was the most ordinary magic core, it was only relative, as long as it was a magic core, it would be many grades higher than the magic crystal.

So Zhao Yan called Baku and Aura over and asked them to watch him use a general-grade magic core to make a goblin engine. Baku and Ola didn't know how it worked, but they quickly learned it. Zhao Yan didn't force it, he used his own concept to tell them that the principle was false, only if they did more and practiced it, in their hearts, there would be a principle that they could understand.

The reason why Zhao Yan used the most ordinary general-level magic core to make this engine was because the new products that needed to use this engine did not require a lot of energy under Zhao Yan's estimate, and the general-level one was completely fine.

Looking at this product on Zhao Yan's table, Bakuola Koppus was dumbfounded. Zhao Yan didn't say anything, and took the three of them to the square.

Zhao Yan put the new product on the ground and said, "Lao Ke, you stand up." ”

Although Cops didn't know what Zhao Yan was selling, he had to listen to him walk towards the new product. The area of this product is not large, just the length of a human arm, two plates with wide soles, and under the wrench, four thick tires, and in the middle of the tires, a relatively small engine specially manufactured by Zhao Yan is installed.

At first, everyone didn't understand why Zhao Yan wanted to make the engine so small this time, but now they understand.

As soon as Copus stood up, a strange feeling rose up.

Zhao Yan continued: "You control your body balance, squat down slowly, and press the button next to the tire.

According to Zhao Yan's instructions, Pupu slowly squatted down, cautiously stretched out his hand, and gently pressed on the green button.

Suddenly, the new product under his feet rushed forward quickly, although the speed was not very fast, but Kops didn't have the heart to prepare, and fell to the ground in embarrassment.

Zhao Yan smiled slightly, this automatic skateboard was successful.

In fact, the design of this shape is completely made according to the appearance of skateboards on the earth, the difference is that the tires under the skateboard are much louder than normal. And the whole product looks like the tire is the most conspicuous. Then, of course, this is not Zhao Yan's desire to satisfy the visual effect, but after full consideration, the purpose of this skateboard is different from that on the earth, it is just for entertainment, which is really used for traveling.

"Ouch. Koppus slowly got up, touched his ass and shouted, the sudden fall just now really hurt this "powerless" guy. Zhao Yan stopped in front of the skateboard, grabbed it, and pressed

When you press the button, you don't move.

"What the hell is this?" asked Patriarch," asked Kopp. The goblins couldn't help but want to ask, and when they saw that Koppsi asked first, they stared at Zhao Yan with curious eyes. They knew in their hearts that what the new patriarch had made must have a practical purpose.

Zhao Yan dangled the skateboard in front of him and said with a smile: "This thing will be your means of transportation in the future." ”

"Vehicle?" Copus pointed with wide eyes, "just it?"

Zhao Yan smiled, put the skateboard on the ground, stepped on it himself, then squatted down and pressed the button, and immediately rushed forward with the skateboard.

On the skateboard, Zhao Yan swung his body, changing his posture, sometimes squatting, sometimes standing, and as his body moved, the skateboard also changed direction. For a while, Zhao Yan circled around the square several times, not only attracting many goblins to watch.

After Zhao Yan stopped, Kops and the others were already dumbfounded.

Zhao Yan was slightly happy, quite old, and he was a skateboarder. Even if you don't have a goblin engine, you can still play with it.

As soon as Zhao Yan stepped on one end of the skateboard, the skateboard bounced up, and as soon as he took it with both hands, he grabbed it very neatly in his hands.

"Patriarch, you're amazing. The onlookers burst into applause.

Zhao Yan smiled at Kopusi and said, "Old Ke, this is actually very simple, as long as you master the balance of your body, you can control it very easily." ”

"This ......," Koppus hesitated.

Zhao Yan knew that he was scared by the fall just now, and said softly: "As long as you learn it, it is worth falling a few heels." Think about it, how convenient it would be if you used it the next time you went to the dwarf tribe? How much shortened the time to go back and forth? When you see the blisters on the soles of your feet, don't you feel a little heartache? Don't you feel lonely and empty when you think of that boring and tired trip?" Zhao Yan took the skateboard and swung it, "But as long as you use it, all this will not be a problem." ”

After finishing speaking, Zhao Yan felt like he was shooting an advertisement.

However, Zhao Yan's words did move Kopusi, and Kopusi hurriedly nodded and said, "I learn! I learn!"
