Jiao Ming thought about the next work plan, it was better to make a slight adjustment, and then let these people go back to sleep, after all, these people are used to going to bed early and getting up early. But I didn't want Luohua and Nonorme to change their faces on the spot, and Huang Xia also said that it was just a joke, please don't take it seriously.

Jiao Ming didn't expect such consequences to be caused by casual words, so he had to sincerely explain that this was not angry talk, but that the next work was to improve the details of the drawings, and there was no need to fiddle with the vines.

"Really?" asked Luohua timidly.

"Of course, after getting along for so long, I am a person who loves to be angry in your eyes?" Jiao Ming calmed down and went back to sleep, then calmed down and began to improve the vine circle, and at the same time introduced the double-layer technology, combining Emily's technology with the knowledge that he originally stole from Semeer's mailbox, the new version of the three-layer ultra-long-distance teleportation circle inside and outside gradually took shape on the paper.

"Interesting!" a familiar voice rang out in the room.

"It's a must!" Jiao Ming, who was engrossed in the work in front of him, subconsciously continued, and then realized that something was wrong, and suddenly turned around to see Emily's expressionless face. Jiao Ming's mind turned sharply, and he tried to observe the words and expressions, but he couldn't see more, so he had to be surprised, and asked tentatively, "Master, are you back?"

Emily didn't answer, just picked up the drawings and looked at them carefully, and after a long time, her eyes returned to Jiao Ming, looking up and down carefully, as if she was looking at a rare treasure.

"The things drawn by the apprentice are still in your eyes......" Jiao Ming was uncomfortable, and could only be slightly relieved by questioning. In fact, Emily's choice has gradually been determined in her heart, after all, the current situation is not the rhythm of old age and death after a fight.

"Follow me. Emily dropped a sentence, then left the Jiao Ming laboratory, turned left when she went out, and came to the place where the two had been fighting for many days. "What do you think about this circle?"

Jiao Ming was overjoyed, it was the first time that the master and apprentice had cooperated for so many days, and he had been asked for his opinion. From the beginning to the present, of course, there have been many ideas, but almost all of them have been silently slapped in the face by Emily's subsequent change plan, and he can only deeply reflect on his ignorance of qi magic, and it is also in this reflection that the level of designing the magic circle has improved by leaps and bounds.

And there is only one problem of thinking that remains, and that is cooperation.

This circle is highly condensed, and the operation modes of different difficulties are superimposed, and if you want to use it, you will take the highest value, so that only qi magicians with more than eight rings can use it. It's like a problem that involves advanced mathematics and can only be calculated by college students. According to Jiao Ming's thinking, it is better to divide the magic circle into multiple layers and complete it with the cooperation of magicians with different ring numbers, so that everyone can save effort. It is like breaking down the same problem into several small problems, with primary and secondary school students completing the simple parts, and college students only responsible for the calculation of the core advanced mathematics part, which is another application of the method of splitting the subject in earth research institutions.

The production of crocodile collar cement and the operation of communication networks can all see the shadow of this division of labor and cooperation.

However, Jiao Ming, who had long doubts, also found the reason why magicians generally cast spells independently: magic countermeasures.

The so-called magic is the use of spiritual power to pull the magic medium and extract energy from the holy demon sea to the material world. To illustrate it metaphorically, mental power can be compared to nerve rays, and the medium of magic is muscles. The magic countermeasure is to interfere with the magic medium through external forces to damage the connection between the two, which can cause nerve endings to be damaged, muscle control weakened, and nerves and muscles completely broken, and the magical talent is completely abolished.

Under such a fundamental threat, in order to avoid pig teammates and suspicious people, it is more reassuring to complete all the details of the magic by yourself. Combined spellcasting is difficult to become the mainstream, and no one has bothered to design and develop related magic circles or magic.

"What about you?" Jiao Ming thought for too long, which made Emily a little impatient, and patted Jiao Ming's shoulder to urge.

Jiao Ming cleared his throat and sorted out his thoughts, first telling the truth that his level in the design of the magic circle was limited and he couldn't give good advice, and then he told the operation mode of the crocodile collar communication network in Emily's increasingly unkind gaze. "The apprentice's idea is to apply this co-op casting model, what do you think?"

Emily, as the master of the Eight Rings, of course, understands the risks of joint casting, but the fact that she allows the One Ring Qi magicians to achieve ultra-long-distance communication also proves its superiority, and she is silent in the trade-offs.

Seeing this, Jiao Ming naturally wanted to add to his suggestion, and said: "As the saying in my hometown goes, people can't be afraid of choking to death and skip eating. One person's strength is limited after all, and the disciples dare to guess that the future path must be to jointly cast spells to improve the power of magic, and we should find a way to solve the problems we encounter, rather than thinking that this way is not going to work when we encounter difficulties. ”

Emily nodded slightly, as if she agreed, but she didn't know whether to approve of the idea of joint spellcasting or the spirit of studying to face difficulties, and after a short silence, she finally gave Jiao Ming a happy answer: "Reducing the risk in joint casting will be a subsidiary research topic...... Sounds like a good idea, so let's talk about any new ideas based on that?"

"Generally speaking, it is to layer the magic circle, the outer layer is simple, the inner layer is complex, the rough part is operated by the low-ring magician, and the core part is handled by you personally, so that if it goes well, you can use your precious spiritual power in the critical places without waste, and the effect of the circle will be even greater. ”

Emily came to the desk, revised and revised the drawings from last night, and quickly stuffed a new drawing into Jiao Ming's arms: "I'll go back and get some experimental materials, you move this wooden box out first, and then arrange the vines." ”

Jiao Ming smiled and said, "The apprentice has the order." ”

Emily patted Jiao Ming on the shoulder in encouragement, and then disappeared into the room with a flicker as usual.

It's really convenient, Jiao Ming thought so, and then started to work, and when he was halfway done, there was a fluctuation in the space in the room.

Emily held on to a two-meter-square metal plate floating ten centimeters above the ground, slapped it twice, made a dull sound, and said quite ostentatiously: "This is the whole family of the teacher, if you fail, you will have to wait for the research materials allocated by the Magicians Association next year." ”

Jiao Ming frowned and asked, "Can't you go back to the furnace?"

"What's the refurnace?"

Jiao Ming was stunned by the rhetorical question, frowned and asked another question: "How do you use these metals?"

"Of course, it's to cut it into pieces with spatial cracks and hollow out the circle. Emily replied happily, but the doubt in her eyes did not disappear, waiting for Jiao Ming's explanation.

"What to do with the hollowed-out scrap?"

"The Wizards' Guild recycles and exchanges half the weight for new experimental materials. Emily said this, suddenly clapped her hands as if she remembered something, and called: "I almost forgot, your little girlfriend is the young lord of the crocodile leader, is it the one who understands alchemy!? Is it an alchemy term for returning to the furnace?"

"Sort of. Jiao Ming smiled bitterly and said perfunctorily, and then asked, "How much do you know about the magic knowledge of metal?"

"Call Master!" Amily corrected immediately.

Jiao Ming has always been a little awkward about this title in his heart, and it will be a simple title that is not in line with etiquette if he doesn't pay attention to it, but in the past, Emily just let it go without much care, and solemnly pointed out that it was the same as asking Jiao Ming's opinion, which was the first time, which also showed that Emily paid more and more attention to Jiao Ming.

After Jiao Ming lowered his head and admitted his mistake, Emily said slowly: "Metal is an indispensable material for arranging a qi-based magic circle, and it has a special affinity for the distorted space......"

Jiao Ming hurriedly interrupted: "I'm asking about the metal itself. ”

"It's expensive...... It's rare......" Emily rolled her eyes and thought for a moment, then added, "It's still hard." ”

"It's me who asked. Jiao Ming sighed and continued: "Does the master know what will happen if this thing is heated?"

Emily was stunned for a moment, staring at Jiao Ming's face and asked tentatively, "Will it ...... Explosion?" Seeing that Jiao Ming's expression was wrong, he quickly changed his words: "Will it glow?"

"It's going to melt. Jiao Ming was completely speechless, to Emily, and also to this world where knowledge was severely blocked.

"How can metal turn into water? ”

Scolding to be honest, no one believed it, and Jiao Ming carefully distinguished the meaning of melting from ice melting into water melting, which felt as painful as writing a small essay in lingua franca. In the end, Emily was still skeptical, so she had to fall into the experiment: "These are all true, they are the core secrets of alchemy, if you don't believe it, you can verify it on the spot." ”

Of course, Emily will not lack curiosity and curiosity, and directly pulls Jiao Ming out of the room.

"Where to go?" Jiao Ming was puzzled.

"Of course, I went to the kitchen to do a heating experiment. Emily carried the magic lamp, the light swaying with a brisk pace. "Also, you woke up those slaves, you don't want to do all this dirty work yourself, do you?"

"The temperature on the stove is simply not enough. Jiao Ming used his backhand to easily pull Emily's figure. "Only the flames of the fire mages will do. ”

Speaking of which, Jiao Ming once again sighed at this world without coal, and at the same time discovered that the fire mage really had a monopoly on the production and recycling of metals in all aspects.

When Emily heard this, she wanted to wake up the ice lotus, but Jiao Ming was unwilling to agree, and repeatedly promised that she would let Master Shi see the metal melt as she wished tonight, and then she revealed the matter.

Once back in the room, Emily proceeded to cut the metal plate with spatial magic, as planned. The experimental materials allocated by the Wizards' Association are two meters square and about ten centimeters thick. With a wave of her hand, Emily cut off a piece of metal that was only one millimeter thick, and then suspended it in the air, and quickly hollowed it out according to the drawing.

And Jiao Ming next to him was an eye-opener, this kind of machining accuracy is not lost to the machine tool of the Crocodile Magic Research Institute five or six times.
