Firearms, or all external devices, are very useful, and it is precisely because human beings themselves are not good at them that these devices were invented.

However, these things are always foreign objects, and sometimes it is really inconvenient to use, and various restrictions will be encountered in different situations, and there are many occasions when they cannot be used.

Just like Dong Chen now, every time he goes to the building of the Cult of Science and Technology, he does not carry firearms, because there is a check when he enters the building, in addition to checking the "level badge" and portrait, a slight body search is also carried out, which is for the safety of the Cult of Science and Technology and internal scientific researchers.

When he went for the first time, Dong Chen cautiously did not carry firearms, because he felt that the armored barbarian guards standing outside were definitely not decorations, and there was no reason to enter so freely on such an important occasion.

As a result, there was a body search after entering, but fortunately he didn't bring the electromagnetic gun, and he was wearing a thin one, and the barbarian guards outside checked the proof, and the Terran guards in the passage slapped twice where the weapons might be hung and let them in.

This is only the branch of the Technology God Cult in Black Rock City, if you go to the Imperial Capital Headquarters, it will be more strict, anyway, it will be a lot more restrictive.

When his energy recovers a little more, he can use electricity or magnetic force to control it, plus Tianshu's "field control" skill, basically no one can hurt him, and even kill the incoming enemy.

Who doesn't bring a steel jump with him when he goes out, that is his powerful attack weapon, and when the energy is sufficient, it is more terrifying than an electromagnetic gun.

It's a pity that a thunderstorm passed quickly, and he didn't know when the next thunderstorm would be, he just hoped that this thunderstorm was just the beginning, not the end.

When the rain was over, Dong Chen finished assembling the remaining chain parts, and put them on the bicycle to try it, and after feeling okay, he went to the school library.

As soon as he entered the library, Dong Chen found that Harry was reading his manuscript, and Dong Chen, who was already familiar with him, walked over and teased, "Yo, I'll ask you to help show the students, by the way, do a survey, why do you look yourself?" ”

"Hehe, the students' reactions are very good, so I was curious to take a look, but I didn't expect to find that it was really good." Harry smiled and put down the manuscript in his hand.

"yes, I feel like I have a talent for it, that's why I want to write science fiction."

Dong Chen said and glanced at the thickness of the manuscript, "There are still people looking at the manuscript?" ”

"yes, someone is watching, and it suddenly has something to do with you," Harry smiled and pointed in one direction, "Look over there." ”

Following the direction of Harry's finger, Dong Chen suddenly saw a bald head on the table between the bookshelves.

"When did there be a bald head in the school, and why hadn't I seen it before? Freshly shaved today? ”

Harry laughed and said, "Freshly shaved, you can see who it is, a daring and mischievous child." ”

With doubts, Dong Chen walked next to the man, and when he got closer, he found that he was really an acquaintance.

And this acquaintance is still a little strange, his complexion is a little red, and he still has a little gauze wrapped around his left hand.

"Wooden beams? Why did you shave your head all of a sudden......"

"Wait, how do you ...... your hands"

"You're the guy who flew a kite to lead the thunder when it rained just now?!"

"Huh?" Mu Liang looked at Dong Chen, who was sitting opposite him, in surprise, "Mr. Dong Chen, you already know?" ”

"Guessed," Dong Chen pointed to Mu Liang's bald head and hands, "I happened to see that kite you flew, why did you suddenly think of doing such a thing?" ”

Hearing Dong Chen ask, Mu Liang scratched his newly shaved bald head a little embarrassed and said, "I'm curious about the energy of thunder and lightning, someone has long proved that thunder and lightning are also a kind of energy, I thought that if I stored them and used them on the airship, then the airship would not need to be loaded with heavy steam engines and fuel, then it could be loaded with more people, and the cost would definitely be cheaper." ”

"Didn't I remember some books documenting similar experiments? It's all ended in failure, and you've looked for similar books to read, so it's impossible not to know. Dong Chen said speechlessly.

"Yes," Mu Liang was still a little embarrassed, "but this kind of thing is finally known by myself after trying it, otherwise there wouldn't have been so many failed experiments, hehe." ”

Although the words are true, I have never seen this kid so reckless.

As a student of the Advanced Mechanical College, Dong Chen also has an understanding of this kid, after feeling that Dong Chen is not strange, he has come to ask Dong Chen many times about the location of the books, and the books he has not found are very biased, so he is familiar with the books that come and go.

His specialty is mechanical structure, but he is more interested in energy and power, because he feels that the current steam power is too small, which seriously affects the ability of machinery, and no matter how the structure is designed, it cannot solve the limitations of steam power.

The end result is that it gets bigger and bigger.

Although the big machine is very majestic and powerful, it is too bulky.

He chose mechanical structures only because his father was a carpenter and had been exposed to things like "structures", so it should be easier to learn, and because there was no academy in the field of energy research in Black Rock City, he could only learn this.

His dream is to be admitted to the "Imperial Capital University" like his brother, the largest college in the Eastern Continent, and it is also a specially established college, as long as he successfully graduates, he is a formal "science and technology reserve", and he can directly conduct scientific and technological research and development to earn points.

That school has a major in the field of energy.

His grades are very good, so he has time to carry out a side job, which is to do all kinds of things that are extremely groundbreaking in Dong Chen's opinion, but extreme in the eyes of teachers and classmates.

Dong Chen is quite optimistic about this kid, Mu Liang's vision is very long-term, and he is very pioneering, but he is a little too pioneering, Dong Chen is afraid that he will hang up before he develops new energy, and can only become a "pioneer" who dedicates himself to the development of science and technology recorded in the history books.

This time the situation was dangerous, and fortunately he ran fast, otherwise he would not have just burned a little hair, slightly burned a hand, and sat here reading science fiction.

"Mr. Dong Chen, this book you wrote is very good, but I think that if the energy of the "car" in your book is replaced by stored lightning energy, I feel that it should be able to run faster, and it can be more lightweight, and it can run to 15 ...... per hour Well, one hundred and twenty kilometers is fine. ”

"Haha," Dong Chen said with a smile, "That's right, I'm also quite optimistic about the development of electric energy, but you kid is too open." ”

"I have to tell you some precautions and experimental standards, don't be reckless when doing experiments, or your life will be lost."

"Does Mr. Dong Chen know these things? Have you done any of these studies as well? Mu Liang asked in surprise.

"I have experience in finding thunder......

Dong Chen stopped halfway through speaking, looked at Mu Liang's bald head and the future, and continued, "It's nothing, although I haven't done your kind of experiment, but I know a lot more than you, and it's more than enough to teach you." ”

"Thank you so much, Mr. Dong Chen."

"No thanks, thank you for your bald head now, you're so lucky."
