In the end, the locomotives prepared by Zheng Yichen were sold, although half of the people bought were alchemists or deputy engineers of engineering, Zheng Yichen could basically guess the thoughts of these people, but there was no additional warning to them, the warnings that should have been explained, don't try to disassemble this kind of thing, the most important place in the entire locomotive, Zheng Yichen has prefabricated strict anti-leakage means.

Those places are all one, and slight deformation is not much of a problem, but once there is a certain degree of breakage, the internal prefabricated means can completely destroy the important core of the locomotive.

As for the exploration of magic, Zheng Yichen said that there was enough magic insulation material inside, and if he wanted to explore, unless he smashed it open, don't even think about anything else!

Anyway, the cost of a locomotive is very low for Zheng Yichen, and the money he earns is enough to buy enough materials to make more than ten additional cars......

On the third day, there were a few more eye-catching vehicles here in Caga City, which made a buzzing sound like a roar of a demonic beast, which scared a lot of civilians who had never seen this thing, people from other worlds are not stupid, these locomotives come with their own manuals, and the locomotives have magic enhancements on them, and even the paint will not fall off if you fall casually, enough for beginners to toss it.

As for the charging of mana, it was originally enough to build a mana gathering in the internal mana source, and the free elemental power gathered by the magic array was enough to maintain the consumption of the locomotive, and Zheng Yichen still used Yilin's improved mana gathering, and the magic fluctuations emitted were slighter, and the efficiency was still very high.

It's just that Zheng Yichen feels that this is too lofty, even if he doesn't have much curiosity about the locomotive, after discovering this, he can't help but want to take it apart and peek into its secrets, you must know that the magic of magic gathering will also dissipate, after all, it only gathers the free power of the outside world and transforms it into non-belonging magic power, and it will not be supplemented by magic itself.

Yilin's improved mana gathering can ignore such shortcomings, and coupled with Zheng Yichen's ability characteristics, the magic power gathering blessed on the mana source is even more special.

As long as it is in an environment with sufficient free energy, it is not an exaggeration to say that the source of magic power is a perpetual motion machine...... Actually, there is a loss of use of equipment, even if the magic is fine, there will be problems with the carrier after a long time, it can't be said to be a real perpetual motion machine, and the upper limit of output is also a problem.

"This kind of thing ......" Diya looked at a 'locomotive' in front of him and gently rubbed his forehead, this car was sent by the branch members in Kaga City, because the place of the transaction is here, the Templar Church has a lot of money, so it bought more than half of it at once, most of it was sent away for research, and a small part is currently used for experiments, so Diya was naturally sent over here.

She opened the envelope and glanced at it, her helpless expression immediately became serious, the origin of this locomotive seemed to be the same...... Especially in terms of production style, the Templar Church once destroyed a lot of Zheng Yichen's alchemy incarnations, and although the core of those incarnations was completely destroyed, some production styles were recognized.

These locomotives also have that type of style.

"Things seem to be happening one after another. She sighed, the matter of the undead witch has not been resolved, a new witch has appeared again, those magic items are all 'real', and in three days, at least two hundred magic items of the same type have appeared in Kaga City, and the Templar Church has not been able to recover them, as for Oss and others, who should have been caught in the whirlpool, after she took the magic items from him.

It doesn't seem to have anything to do with it, and not many people pay attention to them until now, paying more attention to the key magic items scattered around.

Now Zheng Yichen has a new move, what is he going to do to sell this strange 'car'?

Since it's an experimental use, let's try it?

Reaching out and gently touching the body of the locomotive, the paint on the body is extremely smooth, the feel is soft, the streamlined body structure, plus those hard lines, is indeed very attractive, look carefully for a while, she couldn't help but sit on it, looking at the envelope with the manual.

"Well...... Twist the key first?Is this it?" After confirming the location of the key, Diya twisted the switch indicator of the locomotive to the 'on' top, and then the pointer on the dial of the front of the locomotive moved, she continued to look at the manual, and glanced at the dial of energy, and the pointer touched the top, which means full energy.

The large dial at the bottom is the speed hand.

The design of the dial, Zheng Yichen did not get very detailed, the speed calculation of the two worlds is different, naturally can not refer to the way on the earth, about the dial of the speed pointer, Zheng Yichen did not get any value at all, just divided it with black, red, yellow and blue areas, the blue area means 'safe speed', the yellow word is 'pay attention to safety', and the red one is 'dangerous speed', black is extremely dangerous, and the other dial is the energy detection of the magic source.

The activation strength of the magic power gathering is based on the strength of the throttle, and the mana consumption of the locomotive is always a little worse, and when the magic power of the mana source is less than ten percent, the magic power gathering will be temporarily invalidated.

"What is the gear? Uh, the precise start of the gear can save energy consumption? What is the clutch?"

A manual that didn't seem to have much content, and it took Diya nearly half an hour to write it down: "It seems to be quite simple after understanding...... Give it a try. ”

With an expectant thought, she followed the instructions in the manual, and when she was ready, she unscrewed the accelerator directly, and the wall in front of her rumbled......

"Ahem, the 'gear' is wrong?" Coming out with a puff of smoke, Diya coughed lightly, looking at the wall that she had crashed through, and the car was protected by her, so there was no damage, just this wall...... Forget it, someone will repair it, as for the two extra scratches on the ground, it was not the wheels that rubbed out, but she pulled it out on the ground with her feet, and she completely forgot the function of the brake just now.

"Try again. She picked up the locomotive that fell to the side, looked back at the hole in the wall behind her, lifted the car with one hand, turned it in one direction, and carefully re-debugged it, this time she didn't dare to screw the throttle directly to the end, it was very slow and gently twisted the throttle, the car was running, but because the speed was too slow, the moment her feet were slightly off the ground, the locomotive fell to one side......

"Ahh

Diya shouted a little frantically, let her learn some combat skills or magic, she said that it was easy to learn, this kind of novelty that she had never been exposed to, she was afraid of breaking things if she used force, and she was light and didn't move!?

"Ah~ so idle. Zheng Yichen lay lazily in his laboratory, probably pressed by the matter of the demon soldiers, after returning to the nest, he felt that his state had inexplicably fallen into a sluggish stage, what to do, he just wanted to lie here, almost like a waste dragon.

The enlarged Demon Soldier Summoning Book was spread out in front of Zheng Yichen, why did those locomotives wait until the third day to be shipped? The reason is very simple, because Zheng Yichen spent more than a day leaving a back door on it, and it wasn't something that could be directly detonated by taking out a remote control.

It's a backdoor linked to the Demon Soldier Summoning Book, and part of the magic power injected into the magic power source is used to recharge, and the other part will flow into the Demon Soldier Summoning Book, this association is not a complete Demon Soldier Contract, and it is much easier to make than the summoning ring used by Lily.

Anyway, you have to refuel when you drive, and there is no official place in the world to charge for fuel, so I have to do it reluctantly...... Tut-tut, when there are countless people driving Black Dragon brand cars, trucks and even buses in the future, the magic will be recorded in the account, and it will be beautiful to think about it.

Yawning,Bored looking at the content in the Demon Soldier Forum,What he's watching now is a 'video',There's no doubt about it,Photo magic has this effect.,It's just that the magic consumed by this kind of thing is almost the difference between watching pictures and watching videos with mobile phone traffic on the earth.。

It's all magic that can do this, but now this function is being used to show off, the video is a picture of a woman in a fiery red dress driving a motorcycle with flame paint at a gallop, and the hands on the dial suddenly fall into the black extremely dangerous area!

"It's only been a few days, and there has been a drag racing party!?" Zheng Yichen was stunned for watching this video, and rubbed his eyes vigorously, this woman looks a little familiar...... Oh no,, isn't this Dan Marina!?

This woman is really restless...... Zheng Yichen muttered, a little moved, he had done speeding before, but the feeling of drag racing had not been experienced, as for the speed, Zheng Yichen said that there was a locomotive that could complete the speed of the explosion in the video, as for the situation that the speed was too fast and could not be accelerated, he had already thought of a way to make up for it.

The design of the car is that the faster it runs, the wind pressure magic applied to the car will be relatively enhanced, and it will always maintain enough grip, and the tires are blessed with the earth magic that strengthens the land, and the speed will be triggered after reaching a certain height, strengthening the ground to avoid the wheels turning too fast, and the ground cannot support such a high speed, so that the speed can be fully exerted......

There is only one locomotive of this style, after all, it is too troublesome to do, Zheng Yichen has no good way to achieve mass production at present, so he put away the design drawings and left it alone, and there is no chance to drive it!

"Alas~ The more I look, the hotter my eyes become......" Zheng Yichen scratched his head, closed the Demon Soldier Summoning Book, shook his flat wings and walked out, and after walking to the gate of the underground base, Loris's voice came from behind him: "Where to go?"

"Take a breath, I haven't been out for a long time!" Zheng Yichen scratched his head, during this time, in addition to controlling the incarnation to go out, his body has been stranded here in the underground base, and he has not seen the sunlight on the ground for a long time.

I was obsessed with research and couldn't feel anything before.,Now it's suddenly boring.,The effect of staying underground all day long comes out.,He now has an irrepressible inexplicable irritability in his heart.,There was no such situation before.,This thing seems to be the same as a woman every few days of the month.,Indirectly!?

Once the feeling of irritability is generated, it is as difficult to extinguish as gasoline that has been ignited.

"Let's do it together. Loriss looked at Zheng Yichen's slightly trembling eyes, shook her head slightly, walked to his side and said, Zheng Yichen is too 'young' after all, maybe the mentality is very good on weekdays, but occasionally there will be such an explosion of mentality, when she first became a witch, she also stayed in a closed environment for a long time in order to avoid some tracking from the outside world.

At that time, she also had a strong sense of irritability.

"Good. Zheng Yichen couldn't wait to open the door of the underground base to the outside world, the deity saw the sunshine of the outside world for a long time, felt the natural breeze, he exhaled a long breath, and the inexplicable irritability in his heart gradually faded a little.

It's just a little bit, he looked down at his paws, and couldn't help gritting his teeth tightly, after having the mental preparation to become inhuman before, he didn't feel anything, but an inexplicable sense of irritability appeared, and after the mentality exploded, he had a fed up thought, why did he hide here?

He wants to get in touch with more human society, even if it's from another world!

couldn't help but knock his head hard, Zheng Yichen resisted the urge to roar a few times, his wings were completely opened, and a strong turbulence erupted from under him, and the next moment he went straight to the sky, Loris, who was standing on the ground, looked up at Zheng Yichen, who gradually became a small black dot in the sky, waved his hand back, and the camouflage leading to the underground passage reappeared.

This is Zheng Yichen's nest and cannot be exposed.

"Roar, roar, roar~!!"

In the clouds, after feeling that the distance of flying was far enough, Zheng Yichen took a deep breath and roared at the sky, this roar spewed out not only the air current, but also the magic that was affected by emotions, and the clouds around him were affected by the sound containing the impact of magic power, and they were blown away at the first time.

“......？”

Dan Marina, who had just returned to Caja, looked in the direction of the east with a little confusion, and she heard the endless roar of the dragon in the distance, the source of the sound was far away from here, but because of the magic it contained, it was still clearly transmitted here, not only him, but also the people in Caja City heard it, and some of the troops in the city were urgently mobilized to prevent some emergencies.

"Is Xiaolong abandoned? Is it so desolate?" Dan Marina took off the mask she was wearing, and gently pinched her chin with one hand, feeling as if she had a chance to take advantage of it......
