"With fire copper as the cannon chamber, Mithril engraved with the energy gathering array, iron essence as the two-layer cannon body, engraved with the ice array, Lei Gang as the three-layer cannon body, engraved with the energy array...... The Soul Burning Crystal is the guide, and the power of the magic crystal is communicated, and the formation is formed, and the thunder fire is ...... The amount of fire copper, about three units, the amount of Mithril, one unit ......"

In the test ground of Luolin Territory, in the heavily guarded secret workshop, Li Yunfei looked at the alchemy notes in his hand with full attention, and kept taking out the same materials from the space bag and placing them in front of him, while the charcoal pen in his hand kept scratching down, drawing a structural decomposition diagram of a magic guide cannon.

When he really saw the description of the magic cannon in Karis's alchemy notes, he realized that this thing really deserved to be one of the top representatives of the world's magical civilization.

This thing was definitely much more complicated than he had imagined, and the cannon body alone was divided into three layers. The innermost layer is made of high-temperature-resistant copper as the main material, which is used for energy gathering and guidance. The second layer is the Ice Circle, which is used to cool the cannon body. The third layer is the Suppression Array, which absorbs the energy that escapes after the magic guide cannon is fired back into the cannon body, so as to prevent the energy from being unstable and exploding.

In addition to the most basic gun body, there are a large number of other additional structures, all of which are used for stable energy output and other auxiliary functions.

The structure of this thing is not at all simpler than the artillery in Li Yunfei's previous life, but much more complicated.

Fortunately, Li Yunfei had already obtained Karis's alchemy notes, and the explanations in them were extremely detailed, so he could still understand them.

However, despite this, he could only draw a structural drawing first, and it was not so easy to make a physical object.

It would be much more convenient to be able to get a finished magic cannon...... Touching his chin, Li Yunfei thought.

"Chirp, come and pinch the young master's shoulder. Putting down the drawings in his hand, Li Yunfei twisted his slightly sore neck and smiled at the tweet on the side.

At this time, Jiu Jiu was touching the precious materials that Li Yunfei took out from the space bag with bright eyes, and seemed to be more excited than when he saw the gold coins, touching the same materials as Mithril, Fire Copper, Lei Steel, etc., as if touching her favorite cream pudding.

This little girl is knowledgeable...... Li Yunfei smiled secretly. After the little girl fell asleep in the fire magic crystal before, Li Yunfei didn't wake her up, but he didn't expect to wake up until the third day.

I don't know if I'm in a good mood in the magic crystal pile, Jiu Jiu looks more beautiful, the skin is like a baby, and when a pair of big watery eyes blink, there is a feeling of pity for me, and I am a beautiful embryo.

What made Li Yunfei a little strange was that after waking up, the little girl became a lot silent, no matter how Li Yunfei teased her, she just didn't speak. Originally, although she could only say the two simple voices of "chirp", after living together for so long, Li Yunfei was already able to hear her meaning from his simple "words". And now this little girl has simply become a little mute, and she refuses to speak.

Hearing his call, he reluctantly touched those cherished materials, came to Li Yunfei's side, and pinched his shoulders with soft and white little hands.

"Ahem, do you want to eat cream pudding and roast leg of lamb?" Li Yunfei asked with a smile.

"Goo Dong ......" Li Yunfei dared to conclude that this little girl definitely swallowed her saliva!

It's just that although he swallowed his saliva so much, Jiu Jiu still gave him an angry glance and didn't speak.

It's weird...... What the hell is wrong with this little girl?

Li Yunfei couldn't help but feel funny, and was about to **** her again, when Kao's voice came from outside the door: "My lord, His Royal Highness Piller has come down." ”

Thinking of the eldest son of the Archduke Roland, who was a little too kind, Li Yunfei smiled slightly, patted the chirped little hand and signaled her to stop, and casually put away all the materials in the house, and then opened the door of the factory.

I saw that Piller was standing in the center of the test site with a team of guards at this time, looking curiously at everything in the test site, and he seemed to be very interested in the blast furnaces.

"Your Highness Piller, please do not blame for the disappointment. Li Yunfei walked out of the factory with a smile and said.

Hearing Li Yunfei's words, Peeler immediately turned his head, smiled like a spring breeze, and said, "Where is Sol, I disturbed your business, if you want to blame, you should blame me." ”

As he spoke, he had already come to Li Yunfei's face, looked at Li Yunfei a few times, and suddenly opened his arms and hugged Li Yunfei fiercely.

Li Yunfei couldn't help but be surprised, slightly surprised in his heart, and raised his hands and didn't know where to put them.

I rub this His Highness Piller will not be...... That's it, right?

"Thank you...... Thank you...... Thank you......" Piller's voice came in his ears, sounding even trembling slightly, and he seemed extremely excited in his heart, "My father's temperament is extremely tough, it is absolutely impossible for him to accept the conditions of Lingyun King City, if it weren't for your fire demon essence, my father would probably ...... Thank you ......."

It turned out to be for the Grand Duke of Roland! Li Yunfei was relieved.

Gently patting Piller's shoulder, Li Yunfei said in a deep voice: "His Royal Highness Piller doesn't have to be like this, as a courtier of Iron-blooded Roland City, the safety of the Grand Duke is closely related to the fate of us, and Sol should do this." At the same time, I sighed in my heart, this Piller is a dutiful son, much better than Bernie's bastard.

Piller let go of Li Yunfei, and at this time, his eyes were already slightly red because of excitement, and he suddenly bowed deeply to Li Yunfei again, and then raised his head.

From the look in his eyes, he could see that he didn't want to say more words of gratitude, and could only express them with actions in the future. Then he clapped his hands, and immediately several attendants came over carrying a black box and placed it in front of Li Yunfei.

"Thor, my father told me that money is nothing to you, and this kindness cannot be measured by money, I know that you are an earth elemental resonator, a genius magician, so this time I found a set of basic magic books from each department, plus bronze and black iron earth magic books, as well as the magic notes of several black iron mages, it is a little careful, I hope you don't dislike it. Piller said with an eager look on his face.

Hearing this, Li Yunfei couldn't help but secretly shout in his heart: I really don't think I have a lot of money! Don't be so polite, I'm just a vulgar person! I just had to smile lightly on my face: "Thank you very much, Your Highness Piller, these things are just right for me." This is not a lie, at this time, he only has one volume of magic books "Earth Basic Magic", if you want to study alchemy, you also need some magic books from various departments to study it, so as to touch the class.

Suddenly, a flash of inspiration flashed in his mind and he asked, "By the way, Your Highness Piller, I have a reluctant request that I don't know whether to say or not." ”

Piller immediately waved his hand and said, "Sol said that as long as I can do it, I will definitely do my best to help." ”

"This, I have been studying war equipment during this time, I have come into contact with alchemy, and I am very interested in magic cannons, can you lend me one of the magic cannons I bought from Wang Cheng last time, let me study it? Li Yunfei asked. Someone sent a pillow when he was really sleepy, and just now he wanted to get a magic cannon, and this Piller was immediately delivered to the door.

Hearing that this was the case, Peeler immediately agreed: "No problem, if you can really make stronger war equipment, it will be a blessing for us Roland!

"Silver Spider!?" Hearing this familiar name, Li Yunfei couldn't help but be stunned.

"Yes, doesn't Thor know, a legend among alchemists, a genius who was once rare to see in a thousand years, the inventor of the magic cannon, the silver spider Karis!"
