Li Yun spent two days to understand the history and scientific and technological civilization of this world, and combined with the knowledge plundered in his brain, he could be regarded as a preliminary clarification of the essence of alchemy-

It is not as unbearable as Fang Qingshui said, but after thousands of years of development of goblins, alchemy has long evolved into a huge and strict discipline, and it is the cornerstone of the entire goblin world civilization.

The reaction of alchemy is divided into three processes: the analysis of matter, the decomposition of matter and the reorganization of matter, which can also be disassembled and called analytical, dissociative and modeling, which in the goblin world, it is like the language and mathematics on the earth, it can be said that every goblin knows one or two.

Among them, the analytic technique is the earliest, and it belongs to the textbooks that exist in elementary school, and the dissociation technique can only be learned by goblins after they enter junior high school because of its certain dangers, and the modeling technique has the highest requirements for mental power, and it is only when they are promoted to high school that Li Yun has the opportunity to contact this school now.

But even so, in the goblin world, goblins who can fully master alchemy also belong to the category of geniuses, which is equivalent to the top students of the earth school in the previous life, not to mention one in ten thousand, it is also rare in a thousand, and a school of two or three thousand students can train three or four at most.

However, success is also alchemy, defeat is also alchemy, and it is precisely because of the convenient weapon of alchemy that the scientific and technological development of the entire goblin world can be said to be extremely deformed.

Many basic disciplines do not exist, not to mention, theoretical knowledge is also a little bit east and west, bumpy and bumpy, extremely unsound, and there is a bit of empiricism, the civilization of the entire goblin world, in his opinion, is like a child holding an artifact, all day long studying how to use, rather than more essential exploration.

In other words, the goblin world is relatively developed in applied science, but the most fundamental basic science and technical science are still in the embryonic stage, which can be said to be quite nondescript and very 'unscientific', and because of the outbreak of war, the academic environment of the entire goblin world has been greatly emasculated in response to the needs of the war, so that the little theoretical knowledge that has just emerged has completely lost the soil for growth and has been abandoned.

And after abandoning the best opportunity to explore the world, alchemy has once again become the only lifesaver for goblins!

It can be said that a goblin's mastery of alchemy basically determines whether he can be admitted to a key university, because the lowest alchemists have a diploma from a second-class college, can directly apply to become a federal researcher, and enjoy various federal allowances.

If it is a little worse, it is equivalent to a modeler graduated from a three-class college, belonging to a senior engineer and management talent, and even worse, a dissociation teacher who graduated from a vocational and technical school, belonging to the backbone class, as long as he works hard, he can also worry about food and clothing.

As for the worse -

Maybe they still have a lot of choices before the goblin world falls into the war, but during the war, this kind of goblins with the largest number and the lowest status can only become mecha manipulators, if they don't want to be workers, go to the hole to mine day and night, then become a warrior, with superb manipulation skills and a little luck, hoping to survive in the army, it has become their only way out!

Li Yun's body, that is, Rock Hanselton, including the vast majority of the students in this school, belong to the reserve of the Federation soldiers, but this road is not easy, if he is assigned to the logistics department in the future, it is fine, but once he is arranged to the front line of the Void Battlefield to guard the only one percent of the territory left in the goblin world, it will only be a matter of time before the plane is destroyed and people die.

However, now that Li Yun is here, the fate of this body has naturally changed.

......

"I see—"

Looking through the textbooks of the past, when Li Yun learned alchemy, he finally understood the biggest reason why it could not be used in all realms.

In fact, the problem is not in alchemy, in essence, alchemy is only a relatively unique method of spiritual use, and the reason why it cannot be effective in other worlds is because, in this world, it seems that all matter has a magical plastic factor.

And alchemy is the key to knock on this door, to sense its existence through analysis, and then to mobilize and change it through dissociation and modeling, which completes the gorgeous transformation of alchemy.

It can be said that this magical controllable alchemy factor is the biggest feature of the goblin world, and it also surprised Li Yun, who discovered this.

"However, in this way, if the essence of the goblin world is this alchemy factor, then what about the martial arts world?"

"Could it be the aura of heaven and earth?"

I couldn't help but think of this in my heart, but the movements in Li Yun's hands did not stop, thanks to the development civilization of the deformed goblin world, after understanding the related nature of alchemy and this world, he quickly found a suitable 'research and development project' and began to study it......

Day 3.

According to the agreement, Li Yun carried a 'alchemy drawing', asked for leave and walked out of the school gate and went to the old goblin's residence.

And as early as in the past three days, according to the information sent back by Li Yun, they prepared a variety of materials for him, just waiting for him to prove his strength, so that they could have the confidence to help Li Yun plan to enter Husson University.

"Tin copper, three-stage iron, hard wood, and two low-grade magic stones, these are all brought according to your requirements, is it really enough?"

The old goblin asked suspiciously, there were still three goblins standing beside him at this time, one was his homeless man's men, and the other two goblins were neatly dressed and meticulous, as if they were grassroots personnel who had broken into the Federation, and they also frowned at him, waiting for an explanation.

"This is my alchemical drawing. ”

Li Yun didn't say anything, and directly threw the drawings in his arms to the old goblin, and he squatted down and picked up the materials.

He first picked up the magic stone unique to the goblin world, waited for a while, and saw that the morning light still did not react, then regret flashed in his heart, and instead he picked up tin copper and three sections of iron, and the fifth-level alchemy was unleashed, and suddenly, he saw that the two pieces of metal melted like wax, and fused with each other, turning into golden blocks, which quickly stabilized.

Li Yun picked up another piece of hard oil wood, and as soon as his spirit moved, he saw that the wood block had also melted, and finally turned into a cylinder, smooth inside, and then the golden block changed again, dividing a long filament, rolling up the hard oil wood layer by layer......

"What is this?"

The body of the old goblin obviously did not have any advanced education, and he couldn't understand Li Yun's behavior, let alone the drawings in his hand, so the well-dressed middle-aged goblin on the side took it.

"What seems to be some kind of small arms?"

After only two glances, the middle-aged goblin somewhat understood the principle of the drawing, "And it also uses the alchemy pattern to convert the energy of the magic stone into thunder and lightning, which is a small sidearm of some kind of electric shock?" ”

Li Yun glanced at him when he heard this, and said: "The power of this weapon completely depends on the material and energy, I am just making a template now, when the time comes, you only need to submit it to Husson University along with the drawings, I believe they will understand." ”

The middle-aged goblin didn't speak, just nodded, and just watched Li Yun quickly make weapons.

After a while, with the assistance of alchemy, a simple launcher appeared in Li Yun's hand.

"Alright. ”

As he spoke, he pointed the launch port at the corner where no one was around, put a metal bead in the groove on it, and activated the weapon in his hand without waiting for a few people to speak.

Sou.

The next moment, I saw a black shadow flash, almost no sound, and there was a crisp bang in the corner, and I saw that the metal bead had been deeply embedded in the brick wall, making people's pupils shrink.

"That's it. ”

Li Yun shook the 'weapon' in his hand at this time, and introduced, "As long as it is made larger, the barrel becomes longer, the material is improved, the friction is reduced, and finally sufficient energy is provided, its power can be increased by hundreds or thousands of times!"

"Shhh ”

Seeing Li Yun's demonstration and hearing his explanation, the old goblin finally understood at this time, and couldn't help but gasp and asked, "What is this weapon called?"

"Locke cannon!"
