Before he could officially perform the Brainstorm technique, Xiu Shu had to do some preparation.
He first got up, drew the office curtains, locked the door, and then walked to the open space in front of the desk.
Then Hideki pulled out a storage scroll from his pocket, opened it, and took out six hats that were stacked together.
The hats look similar to the top hats that traditional magicians wear, and come in different colors: red, yellow, green, blue, black, and white.
At the same time, each hat is inlaid with a gemstone of the same color as the hat, and there are many faintly visible strange patterns painted around it.
Hideki first picked up a blue hat and put it on himself. After thinking for a while, he took out a white, red and green hat and placed them on the table.
After he was fully prepared, he began to make seals with his hands.
"Shadow Clone Technique!"
The next moment, three puffs of white smoke exploded, and three figures who looked exactly like Xiu Shu suddenly appeared in front of him.
As soon as they appeared, they rushed to reach for the hat on the table without waiting for the original body's instructions.
After two whoosh sounds, the two shadow clones had already grabbed the red and white hats.
The shadow clone, who was a little slow due to his position, had to put on a bitter face and reach out to the remaining green hat, mumbling:
"I know this is imitating the use of the six thinking hats, but can't the green hat be replaced with a different color?"
The so-called thinking hat is actually a method of thinking management that Hideki has known all his life.
It compares different thinking angles to hats of different colors, allowing people to think about problems more systematically and comprehensively by switching "hats".
For example, Hideki, as the entity, wears a blue hat, which represents planning and command. He is responsible for regulating the entire thinking process and drawing conclusions at the end.
The white hat represents objectivity and focuses on information collection, while the red hat represents emotion and emphasizes feelings and perception.
The yellow hat represents optimism and is responsible for providing positive views, while the black hat represents pessimism and is responsible for providing negative and skeptical views.
And the last green hat naturally represents forgiveness... No, it should be creativity, which is responsible for providing solutions to problems and innovative ideas.
In order to make more efficient use of his genius time of no more than three minutes a day, Xiu Shu borrowed the idea of thinking hat to think about problems more comprehensively.
And because of the existence of shadow clones, Xiu Shu does not need to change "hats" one by one to change his thinking angle, but directly assigns a specific thinking angle to both the original body and the shadow clone.
In this way, not only can you think about the problem comprehensively, but the shadow clones with different thinking angles can also communicate in real time, which is more likely to inspire unexpected inspiration.
So theoretically speaking, there should be six people including the original body and shadow clones in order for this technique to achieve the best effect.
It's a pity that Hideki doesn't have enough chakra, and the more shadow clones he has, the greater the load on his brain.
Therefore, creating three shadow clones was the best choice that Xiu Shu came up with after many tests.
After the third shadow clone reluctantly picked up the green hat and put it on, Hideki's real body and the shadow clone sat cross-legged in the open space.
Seeing that the clone was ready, Xiu Shu raised his right hand in front of his chest and said softly:
"Headstorm Technique."
As soon as the words fell, four thinking hats shot out clear and visible chakra lines from the gems, connecting with the thinking hats on both sides to form a blue square.
At the same time, the heads of the three shadow clones suddenly tilted back, their eyes rolled up, and their handsome faces became a little distorted, looking as if they were experiencing considerable pain.
The strange patterns around the Thinking Hat gem suddenly became visible, forming a series of faintly glowing rune spells.
Xiu Shu did not have the time and means to systematically learn the sealing technique before, so he only learned a little bit of the basics.
Therefore, the function of these rune spells derived from sealing techniques is very simple, which is to limit the flow rate of chakra in the chakra line.
In this way, although the speed of information exchange will decrease, the burden on the shadow clone's brain will also be reduced, and it will not explode due to excessive load all of a sudden. The final effect will be better.
As for the real Hideki, he was concentrating with his eyes closed, and his expression was not as exaggerated as that of the shadow clone.
Because the subject's brain is not a disposable item that can be destroyed without any regrets, it is not responsible for specific thinking work.
Hideki's task at this time is to evaluate and regulate the various ideas generated by the three shadow clones through crazy communication and thinking, and determine whether to continue to dig deeper in the corresponding direction.
Even so, processing a large amount of information in a short period of time still gave Hideki a headache for several hours afterwards.
However, compared with the effect of this technique, paying such a price is already very worthwhile.
Moreover, after using this technique many times, Hideki discovered the unexpected benefits it brought.
Perhaps it is similar to the principle of muscle training. After each headache, Xiu Shu would find that his mental energy increased slightly.
Although the effect is not very obvious, but little by little it adds up to a lot, and Xiu Shu gradually develops quite good mental strength.
In addition to gradually extending the time it takes for the shadow clone's head to explode, it also allows Hideki to become more adept at controlling chakra.
Thanks to this, he was able to master the technique of controlling puppets with chakra lines in just a few years.
Therefore, Hideki always consciously adjusts the chakra restriction technique of the thinking hat, so as to create an appropriate burden on the brain for training during the performance of this technique.
Three minutes passed quickly.
At this time, smoke began to come out of the heads of the three shadow clones, and then they exploded one by one with a bang, leaving only three top hats floating lightly on the ground.
The remaining chakra of the shadow clone began to return to the original body, and the memory of the previous thought also flooded into Xiushu's brain, giving him another headache.
But the rich harvest still made Xiu Shu stand up in surprise and shout:
"Eureka!"
However, Hideki did not start sorting out the harvest immediately. Instead, he took out a bottle of strawberry milk that he had prepared in advance from his pocket and drank it all in one gulp.
Because the brain storm just lasted for three minutes, a large amount of sugar in his body had been consumed, and it had to be replenished immediately.
After replenishing his sugar intake, Hideki massaged his temples with both hands to relieve his headache while pacing back and forth in the office, sorting out his gains this time:
"Such a simple solution, how come I didn't think of it just now?"
"The reason why it is difficult for small puppet beasts to become teaching tools right away is that the students are probably not even proficient in making chakra lines now, so they can't use them for training at all."
"But the creation, maintenance, and even manipulation of chakra lines are ultimately the external manifestations of chakra control."
"So as long as it can help you train your chakra control, you don't have to stick to using chakra lines to control it from the beginning."
"Maybe we can design an auxiliary ninja tool first."
"Even if students don't know how to create chakra lines, they can use them to control puppets and practice chakra control at the same time."
"It's like putting on training wheels when you're learning to ride a bike."
"Instead of letting children fall and get frustrated at the beginning, it is better to give them some assistance and let them experience the fun of riding a bicycle first, and perhaps they can make faster progress."
"——Of course, how to prevent them from becoming dependent on the 'Assistance Wheel' is also a problem that needs attention."
In just three minutes of genius time, Xiu Shu had figured out how to improve the small puppet beast so that it could meet the requirements of becoming a teaching aid.
In order to avoid forgetting the details, Xiu Shu quickly sat back in his seat and began to write furiously on his notes.
When he put down his pen, Xiushu realized that he had already written more than ten pages of densely packed notes.
Because it not only contains the basic form of teaching aids, but also how to upgrade them in the future to adapt to the level of students, Xiushu has already made a lot of plans.
"Everyone will be surprised tomorrow."
Hideki looked at the teaching aids he had just designed, and thought about how shocked the little ninjas would be when they saw the finished product, and the corners of his mouth couldn't help but curl up with joy.
But now is not the time to rest.
Although Xiu Shu still felt a dull pain in his head, he just wanted to have a good sleep.
But in order to make the teaching aids before tomorrow's class, he had to start preparing immediately...
