The spell model is the basis for most mages to cast spells, and a spell model must be built in the sea of consciousness in order to convert magic into spells through it.

There are thousands of spells in the world, and the number continues to increase as scholars continue to research and create.

Even for the same spell, there are countless ways to build a model, and depending on the scheme, the effect will be different.

Some schemes are designed to be stable, making the model less likely to collapse when casting spells, and reducing the risk of backlash; Some schemes pursue explosive power, and the spells released tend to be more powerful and more lethal.

Stability and explosiveness are often contradictory, and if you want to pursue more stability, you will inevitably sacrifice some explosiveness, and vice versa.

Yi Chen took a serious look at Ning Xiaoyu's scrap draft, and probably understood her thoughts, most likely wanting to find a balance between stability and explosiveness.

It's just that the overall level of the model is too low, and if a perfect model has a total value of ten, she can only calculate these to reach four at most.

If you pursue balance again, then the stability and explosiveness are probably only two, too mediocre.

If the overall quality of the model is not improved and the total value is expanded, no matter how much you adjust, it is impossible to get a satisfactory result.

"The school should have given you a standard model, why do you have to work hard to rectify it yourself, can't you just build it according to that model?" Yi Chen asked casually.

Ning Xiaoyu was distracted by those cumbersome models and formulas, and when he interrupted him like this, he immediately slapped the pen in his hand on the table with a "snap", and slanted towards him with a sinister gaze.

Yi Chen was startled in his heart, and his body instinctively leaned back. This little girl's aura is a bit strong!

As if realizing that his reaction was a little overdone, Ning Xiaoyu's face quickly softened and replied, "The standard model provided by the school focuses on stability and is weak, which is not what I want. And I wanted to see if I could improve on what I learned during this time. ”

"The attitude is correct, but if the standard model is too poor, no matter how much it can be improved, it will be limited. Have you ever considered a better model as a reference? Yi Chen propped his hands on the desk and looked at her calmly.

Ning Xiaoyu was a little unhappy, "Are you deliberately mocking me?" If there was a better model of Wind Blade, how would I look into this? In fact, this standard model provided by the school for free is already very good, and we can't get in touch with the better ones at all, and the only hope is to win the school competition, so that it is possible to get a good model or even an excellent model. ”

With that, she sighed.

This is also a gap between commoner students and aristocratic students, noble students can easily obtain better models with their family background, but commoner students cannot.

"Bring me a pen." Yi Chen said suddenly.

"Huh? Why? Ning Xiaoyu was stunned for a moment.

Seeing that there were a few pens on the side of the desk, Yi Chen didn't bother her anymore, nor did he answer her questions, he immediately picked up a pen and a piece of leather paper pressed at the bottom of the textbook and quickly sketched it.

"Why are you doing, this leather paper is very expensive......"

Ning Xiaoyu subconsciously wanted to stop him, you know, the school would only provide her with three pieces of leather paper every month, and she was reluctant to use it at all, and she usually used ordinary white paper.

Vellum paper is made of monster skin, which can carry a certain amount of magic power, and is the best material for recording spell models.

She originally wanted to snatch the leather paper back, but after seeing the pattern drawn by Yi Chen, she couldn't help but be stunned, "This ...... Is this a Wind Blade model? ”

She wasn't sure, though it looked a little like it, but there were many esoteric structures in it that she couldn't understand, and it didn't fit any of the magical theorems and formulas she knew.

In just three minutes, Yi Chen finished drawing this model pattern, and then injected a little magic into the leather paper, and suddenly a three-dimensional wind blade model phantom appeared on the paper, releasing a faint green light.

"It's not bad, it's not rusty." Yi Chen was very satisfied with his work.

Ning Xiaoyu was stunned as she watched from the side, although there were many things about this model that she couldn't understand, but she knew that this was indeed a Wind Blade Technique model, and the quality was far better than the standard model provided by the school and the improved version she had made up herself.

"This ...... Where did this model come from? Ning Xiaoyu stammered and asked.

Yi Chen said lightly: "I drew it, didn't you witness the whole process?" ”

"No, I'm asking where did you get this model solution? Such an excellent model scheme can only be designed by those professors in the school! ”

Those professors in school?

The corners of Yi Chen's mouth twitched, they were able to design a fart, this is an infinitely close to perfect model, dozens of Yi Chen's theorems and formulas are applied in it, and many legendary mages may not be able to understand it!

"You know, my dad is a high-level mage apprentice, and he has also explored several wormhole secret realms, and this Wind Blade model is one of his gains."

Yi Chen casually found a reason.

"It turned out to be the ...... left by Uncle Yi"

After hesitating for a moment, Ning Xiaoyu pushed the piece of leather paper back in front of Yi Chen and said, "This spell model is too valuable, I can't ask for it." ”

"Take it, it's just a zero-level spell, how valuable can it be? As long as it doesn't spread the word. ”

"But ......"

"Don't do it, I'll go back first. By the way, the ratio of explosive power to stability of this model is 6.18:3.82, which is already the optimal solution, and the thinness of the blade is also compressed to the extreme, so it can be directly built in the sea of knowledge without further adjustment. ”

After speaking, Yi Chen opened the door and walked out.

Hearing his words, Ning Xiaoyu was stunned again. Why does he say that the optimal ratio is 6.18:3.82, and the textbook doesn't say 2:1?

Also, why is he so sure that the thinness of the blade has been compressed to the extreme?

In the living room, seeing that Yi Chen came out so quickly, Ning Mu couldn't help but be a little surprised, "So fast, did you encounter any problems?" ”

Yi Chen replied with a smile: "No, Xiaoyu is very smart, she can understand it at a moment, and it shouldn't be long before she can master the first spell." ”

After a pause, he continued, "It's not too early, I should go back too." ”

"Well, okay, you just had a holiday today, you must be tired too, go back early to rest, remember to come over for dinner tomorrow." Mother Ning said enthusiastically.

"No, I won't trouble Auntie tomorrow......"

The original owner was embarrassed to have been eating at the neighbor's house, but he was embarrassed that instead of causing trouble to others, it was better to spend money to order a takeout.

"What's not troublesome, why are you so outside? In the past, if it wasn't for your parents' help, Xiaoyu and I wouldn't know how to survive, but now they're gone...... Oops, look at Auntie's mouth. Xiao Chen, don't be sad, in the future, you will treat Auntie's place as your home. ”

Yi Chen smiled and said indifferently: "Auntie, don't worry, I've figured it out, it's not so difficult to live alone, I can already stand on my own at my age." ”
