Briefly described what rifling is and how it works, and used a wooden gyroscope to demonstrate that rotation can increase stability, and finally used the over-the-horizon range of the earth's guns as evidence, Jin Binglian still looked skeptical, and said: "Why don't you go to the dream space tonight, I'll pick some relevant memory fragments for you to see." ”

"Yes or no, you'll see. I remember why I didn't say this method earlier. Bing Lian said, although there was a bit of blame in her words, her voice sounded as gentle as love words.

"When I first saw the magic of air magic, I thought that guns and solid shells were useless, but when I think about it, there are other details and principles in these weapons that can be borrowed from each other. ”

Binglian nodded slightly, and said: "If rifling really has such a big effect, it is indeed of great significance, and if it is displayed in the academy competition, it is simply a waste to the Magicians Association, which is too much of a loss." ”

All the difficulties that hinder development can be simply boiled down to two points: one is unthinkable, and the other is that it cannot be done. As far as rifling is concerned, the magicians of this world just simply didn't expect it before, but once they see the real thing, they can easily imitate it, and they can also cut out the rifling by slowly pulling out the rifling with the gas magician, which is not the same as being limited by industrial conditions such as precision machine tools and hard milling cutters in the imitation of the earth.

"Or you can also increase the power of the explosion, your powder formula is purely based on the accumulation of blind experience, the size of the base power is completely random, if you can try to match several explosives in the medium chemistry book. It only took a shock wave to overturn that little plate. Jiao Ming made another suggestion.

According to Jiao Ming's understanding, fire magic is to use the fire magic medium to attract energy from the Holy Demon Sea to chemical changes, and then it can be analyzed that the energy released by the explosion of the medicine bag is divided into two parts, one is the reaction of chemical substances in the inside, and the other is the energy from the Holy Demon Sea that is caught by the fire magic medium.

"It's a good idea!, but it's a pity......" Ice Lotus's expression became a little weird, and she shook her head slightly, "Although the formula of explosives is traditionally a secret transmission of fire magicians and apprentices, and is protected in a conventional way, this benefit is on the side of the alchemist, and it is also what Vice President Sasu is trying to change. ”

"You mean, if it is used publicly, it will inevitably be the same as Master Keno's permanent spatial teleportation circle?"

"The method of preparing and dispensing those explosives is not simple, and it is obviously the specific application of a set of complex theories, and it is not something that can be vaguely mixed up by the word 'blind'. And the nine-ring fire magicians under Sasu are not stupid, and I am afraid that they will not even be able to hide 'chemistry' when the time comes. Binglian made the worst prediction, then took Jiao Ming's hand and asked, "Is there any other way?"

When Jiao Ming thought about the countermeasure, he analyzed the pros and cons, the shortcomings of the rifling plan were too obvious, and he had already shot it in his heart, and saying it was just throwing bricks and stones. However, the highly-anticipated explosives program was still on hold, which was unexpected, after all, he thought that the monopoly of knowledge in the wizard circles of this world was a matter of course, but he forgot that this new high-level magic academy was the home base of the faction of Vice President Sasu, and the political goal of this faction was to break this traditional bad habit.

It is strange that you want to follow the tradition here to keep knowledge secret or even monopolize it, so as not to be knocked out.

Facing Binglian's expectant gaze, Jiao Ming had no choice but to come up with the final plan: "It's really not good, just use poison gas." Flip through the chemistry notes, get some toxic gases that are easy to prepare, such as carbon monoxide or something, and stun the opponent to win easily. In addition, smoke is easy to cover up, and even if it is seen through, the reason for 'coincidentally obtained' is in the past. ”

Binglian was noncommittal, but stared at Jiao Ming, until Jiao Ming was uncomfortable, and then asked, "Do you still have a way?"

"There really isn't any. Calling the name and spreading his hands, he realized that he had made three plans in a row that aroused Binglian's suspicions, "Of course, if you have more time to think, there may be, but it is unlikely that it will be simpler and easier than these three." ”

Bing Lian's expression suddenly changed from serious to relaxed, stepped up to hug her, and said with a smile: "You are really a baby." ”

"Baby is not a compliment to a man. Jiao Ming stiffened his face and tried his best to hide his embarrassment.

"But poison gas is not allowed, although the school rules do not have a relevant clause, but this is expressly forbidden by the Wizards Association. The hot breath exhaled by the ice lotus wafted between Jiao Ming's ears: "And the solution is very simple, just buy a metal plate from the Magician Guild." ”

Jiao Ming was stunned for a moment, and understood that he was deliberately squeezing his brainpower, as if he was the joke that used the company's predicament as a recruitment exam question, and then suddenly remembered a movie line: The more beautiful a woman is, the more she can deceive people, is that anxious and depressed look not long ago pretended?

......

The next morning, the weather was cloudy, the cold wind before the rain blew the curtains of the car, the flowers and butterflies fixed the curtains on both sides, the rustle of the leaves was slightly lower, and the three people in the carriage continued the topic of floating trays. According to the information provided by Evan, in the two battles of the academy's fiasco, a disciple of the Master-Apprentice Inheritance Sect used a one-man version of the floating tray and became the star of the entire competition. Most of the inspiration for the Academy's five-a-side version of the floating frisbee came from this.

After that, there are two editions, one large and one small, the author's name and family background, and so on.

"Five people and one person, how can it be that the group of fools in the academy are more advanced?" Bing Lian wondered.

"That doesn't seem to be the case. Evan obviously didn't know the details, "After all, the airship has been built for so many years, and this tray is new. ”

"Probably the smaller it is, the more difficult it is to manufacture, and this should be the truth. Jiao Ming said, although this has been summarized for a long time based on the experience of the earth, it is uncertain whether it can be applied.

"Any blueprints?" Ice Lotus to the core.

"Sorry, no. However, as far as I know, this thing is not complicated, and I believe that Jiao Ming is fully capable of designing and manufacturing. Evan said and nodded slightly to Jiao Ming.

Bing Lian cast an inquiring look, while Jiao Ming nodded in confirmation, and added an extra layer of insurance: "Even if it doesn't work, there is a master behind me." ”

The next topic was some details about this matter, and when the carriage entered the school gate, Jiao Ming remembered that Evan had collected so much information in just one night, and couldn't help but sigh in admiration.

"Where, thanks to the communication box invented by Mr., the family intelligence network can transmit messages several times faster. Evan laughed.

Jiao Ming pursed his lips, knowing that he would not come to the patent fee, so he had to reluctantly say no thanks. After a few people left for a while, I went to the teacher's office to look for Emily, and when no one was there, I put down the exam paper and pressed it with a heavy object, and then turned back to the classroom, where I heard everyone discussing Master Keno's lecture. I wanted to hear the exact time, but before I could mention it, Ms. Keshi walked in and announced the start of the class, and the classroom was suddenly silent.

At noon, the restaurant had a routine lunch, Binglian had a sad face, and when Jiao Ming saw this, he naturally wanted to ask the reason, and then he learned that there was a problem with the purchase of metal.

"Why, the Wizards Association doesn't sell it?" Jiao Mingqi said.

"It's those five people who can't afford it. Binglian replied, with a look of indignation.

"The student council or you pay for it. ”

"Here's the problem, if someone else pays for it, it's an extra aid, and it can't be in the arena. ”

"This ......" Jiao Ming stopped his chopsticks, stimulated the thoughts of the small citizens in his heart with the situation of his family background being involved in the competition, and asked with a turn of his brain: "Isn't the family assistance from the nobles' side counted?"

"As the heir to the top rank, of course, there is a certain amount of 'pocket money', and they are all acquaintances, and the Wizards Association is naturally willing to turn a blind eye to this unclear situation. Bing Lian's voice was lowered, and her eyes swept around unkindly, obviously this differential treatment made her impression of the surrounding noble children drop by three points. "And an acquaintance told me that there are rumors that in order to win, that group of noble children also deliberately used their family connections to persuade the relevant departments of the Magicians Association to suppress the gray-robed students on the point of magic materials. ”

"Really, this group of guys with eyes on the top of their heads would attach so much importance to the gray-robed students?" Jiao Ming questioned, the arrogant appearance of this group of Second Ancestors was really not worthy of such a conspiracy and trickery, but the forest was so big that there were all kinds of birds, and it was difficult to say that there were not a few bad embryos.

"It's hard to tell the real from the fake. Binglian shook her head and sighed, "It's good that our crocodile territory also has an intelligence network like Evan and their family. ”

"So what now?"

Binglian sighed helplessly: "It's really not good, so I will contact Evan and buy the metal directly from the alchemist." Without the intermediate link of the Wizards' Association, you can save a few dollars. ”

Jiao Ming thumped his chest hard, and the food that almost choked him was down, and then he said in surprise: "They tried to kill you twice." ”

"What does it matter, we have killed each other with the Xu Qin people for hundreds of years, and we still have to do business. ”

Jiao Ming was speechless for a moment, thinking about the earth, there are many similar situations, and the two forces that played out the dog's brain yesterday are like glue today. But the prejudice against the alchemist in his heart made Jiao Ming not stop there, and persuaded him with a different way of thinking: "This is Sasu's territory, and we are also working hard to win Sasu's attention, so it is not wise to have a relationship with Sasu's enemies at this time." ”

Binglian subconsciously bit her chopsticks, frowned and pondered for a moment, and said slowly: "As far as I know, this kind of direct trade across the Magician Association is quite common, and there are not a few families behind these students in the school who directly trade metals with the alchemist, so Sasu may not be troubled by this." Moreover, if Sasu really asked about this matter in his busy schedule, according to his philosophy, it was speculated that he would allocate some materials to the gray-robed students. ”

Jiao Ming couldn't think of a reason to refute for a while.

"And one more thing, this is also a sign of weakness to the alchemist. If our plan to steal people is to unite all over the kingdom, there are big forces ready to cause trouble. ”

After listening to this calm analysis of putting aside feelings and only talking about the pros and cons, Jiao Ming only felt uncomfortable, and the delicious food had no taste, and said: "It's a bit of a wretch." ”

"There's no way, we only have two nine rings in the crocodile realm, do you know how many alchemists there are?"

"You know?" the unhappy Jiao Ming immediately retorted.

"There are more than ten on the table, not to mention the hidden, allied and temporary hires, and no one knows how much wealth they have accumulated over the past few hundred years. ”

"Don't talk about it, making the difference in strength clear makes me feel even more guilty. ”
