For the people of the Overworld, the "technological products" of the Heavenly Dao Palace give them an unparalleled experience.

For Fangzheng, however, the whimsy of the Overworld people is just as interesting.

"You know what? I now have a feeling of witnessing history. ”

Fang Zheng stood in front of a change mage's booth with his hands behind his back, looking at the behemoth in front of him, and couldn't help but sigh. This behemoth looks like a rectangular box with five pairs of load-bearing wheels underneath and a small magic crystal turret mounted on top——— to put it bluntly, this is actually the prototype of the Overworld tank.

Fang Zheng had seen in the history books the records and descriptions of the invention of "the first telephone", "the first television", "the first airplane" and "the first automobile" in his own world, which made him very excited. Unfortunately, in his own world, Fang Zheng is just an ordinary game designer, and he has little chance of making history.

But it's just as interesting to witness history.

Although this tank has many flaws, such as the fact that it does not have tracks, and the space inside the car is also very small, because the inventor dismantled a small defensive turret and installed it on this magic car. Even this magic guide car can't rotate freely, but Fang Zheng still looks at it with relish.

At the same time, he had to admit that magic really doesn't talk to you about science, after all, according to science, not to mention anything else, just the current speed of the magic car, and the fact that its body is actually wood——— the huge force generated when galloping alone is enough for the steel turret to crush the car to pieces.

However, after unleashing the Reinforcement Technique, the entirely wood-made body was able to withstand the gallop of steel turrets weighing several tons, and was even able to withstand ordinary bows and swords.........

If this were to be put on Earth, it would be enough to make a whole bunch of physicists doubt life.

"How does it feel?"

Fang Zheng watched the "tank" turn the barrel and smash a target in the distance into pieces, then turned his head to look at Ying Li Li and asked curiously——— this time he came to participate in the magic exchange meeting, he brought Nimfu and Ying Li Li, the former wanted to see his own manufacturing results, and the latter did not need to take an exam.

By the way, Asuna and the black cat are nesting in the Heavenly Dao Palace at this moment, with a handful of snot and tears.

It's also normal, after all, when you've been out and about for a year, do you remember what you learned a year ago?

In order not to mess up this exam, the two had to give up the idea of participating in the magic guide exchange meeting, and began to make up classes in a depressed manner.

Fortunately, there is still Sakura Ci in the Heavenly Dao Palace——— although this is a junior high school student on the surface, but he can be regarded as a regular teacher diploma, and there is no problem in opening a small stove for the two.

"It feels so complicated......... Frankly, I didn't expect magic to be so advanced. ”

Ying Lili's expression was as complicated as her tone, but Fang Zheng could understand her state of mind at this moment. For Ying Lili, the main world is actually a "medieval world that looks full of magic", maybe it is indeed interesting to have magic, but the people here have no Internet, no television, not even radio, and weapons are simple and backward, which more or less makes Ying Li Li from modern society feel a little proud.

After all, even without magic, humans can live a good life. However, the life of most people in this world is obviously not so beautiful in the eyes of Yingli Li.

But when Ying Lili followed Fang Zheng around the magic exchange meeting and saw those "automatic seeding dolls" and "fast portals" and other things, she was not so confident in her own ideas.

After all, there are some things that are very clear even if they are English pears, and I am afraid that they may not be able to be created in their own world for a few hundred years.

However, there is already a prototype here.

"It's not surprising that human beings on the earth have also gone through thousands of years of development before they have changed from primitive people who drank blood to what they are now."

Fang Zheng seemed very calm.

"To be honest, I'm really looking forward to seeing what the world will be like in a thousand years......... provided that they do not die again. ”

That's right, the biggest threat in this world right now is that those mages are too easy to die, in fact, in essence, these mages are not much different from many mad scientists in their world. But the problem is that those mad scientists often have crazy ideas, but lack the power and resources to bring them to life. On Earth, there are many constraints on scientific research, such as resources, money, political support, and government agencies that can shut down research facilities at any time and at any time.

However, in this world, those crazy mages not only have ideas, but also have the ability to realize them with their own hands.........

What's more, there are obviously no human rights or environmental groups in the world that will impose sanctions on these mages. If there really were such a group of fools holding up a sign to protest in the Mage Tower, being burned to death would be the ultimate outcome they could foresee.

You can stop a mage from taking a, but you can't stop a mage from studying magic.

Unless you're getting impatient with life.

"Knock knock!!"

Suddenly, at this moment, a dull gun salute rang out, interrupting the conversation between the two. Fang Zheng raised his head and saw bursts of bright red fireworks in the sky not far away.

"Mr. Fangzheng, is there any activity here?"

"Hmm......... I remember that the head of the Department of Plastic Energy seems to have said that he would show his new discoveries at this magic exchange meeting........."

Fang Zheng thought for a moment, and then made a decisive decision.

"Let's go check it out."

Originally, after coming to the main world for so long, Fang Zheng felt that he had nothing to be surprised about, but when he came to the booth of the head of the plastic energy department, looking at the huge cannon barrel that was dozens of meters high, and the cannonball that looked like a missile erected next to it, Fang Zheng still couldn't help but sigh "I++".

"Ah, Your Excellency Fangzheng, welcome."

Seeing Fang Zheng's arrival, the head of the plastic energy department also came over to greet him with a smile.

"These two beautiful young ladies are your companions, Mr. Fangzheng? It's so nice, it reminds me of when I was younger......... Well, don't talk about these past things, what do you think of me......... What do you think? ”

"It's ............"

Fang Zheng looked at the barrel, then looked at the "missile" next to him, and exchanged a puzzled look with Ying Lili, and then asked curiously.

"May I ask......... Is this what it's meant for? ”

"Explore the sky!"

"Sky?"

"That's right!"

Facing Fang Zheng's inquiry, the head of the plastic energy department nodded vigorously.

"What is beyond the firmament, aren't you curious about this secret? Now, all I have to do is discover the secrets of the Dome of the Firmament! Next, I'm going to put this cabin in the barrel of the cannon, and then shoot it straight into the sky like a cannonball! ”

"This ......... Seems unlikely, right? ”

Hearing this, Ying Lili finally couldn't help but ask.

"Of course, I've experimented before that the thrust of the launch itself isn't enough, but luckily I have a new idea."

As he spoke, the head of the plastic energy department patted the "missile" next to him.

"You see, I've added several mezzanine layers to the back of this cabin, all of which are etched with powerful blast circles. When the cabin is launched into the sky, once it can't continue to rise, I will detonate the magic circle on the bottom layer and push the cabin upwards! In this way, as long as the supply of magic is maintained, I think I will be able to fly to the sky! ”

Did you get all the multi-stage rocket propulsion that the hell meowed?

Looking at the head of the plastic energy department in front of him in a daze, Fang Zheng only felt that he had nothing to say at all, and Ying Lili was also stunned for a moment, and then suddenly remembered a question.

"Then, how do you get down after you go up?"

"Isn't that easy?"

In the face of Ying Lili's inquiry, the head of the plastic energy department was very calm.

"I've already set the plane coordinates in my mage tower, and if something happens at that time, I'll be able to teleport back to the mage tower directly."

If they are heard by the aerospace scientists on Earth, they will definitely be to death.

"Yes......... Why use a barrel? ”

Faced with the answer of the head of the plastic energy department, Ying Lili was speechless for a while, and finally she had to ask another question that puzzled her, and the head of the plastic energy department laughed.

"Isn't this nonsense? If you don't have a barrel, what should I do if it is crooked? ”
