Once Uchiha Rei becomes Hokage, that's when she can truly exert her power. With Konoha providing cover, Uchiha Rei's Second Body can expand aggressively in the Land of Rice Fields.
If anyone were to see through Uchiha Rei's ambition, it would undoubtedly be Sara, who had experience as a queen. She is now the head of the Cultural Department in Sound City.
However, Sara didn't care. As long as the residents of Lou Lan could live good lives, none of that mattered. She believed there was nothing good about being a queen.
If Uchiha Rei knew Sara's thoughts, she would definitely think it was humblebragging. Sara had been a puppet queen for over ten years, never experiencing the taste of power, so it was natural for her to feel that way.
Although Uchiha Rei didn't care about power, she knew that to achieve her goals, she had to wield it. Whether it was establishing Sound City as its mayor or becoming Hokage, it was all to achieve her objectives.
Unfortunately, she was still too young. Becoming Hokage at eight years old was unheard of. Even after the Third Shinobi World War, Uchiha Rei would only be around ten, and when the Nine-Tailed incident in the original story happened, Uchiha Rei would be less than fourteen.
Could she become Hokage at fourteen? That was a question, but Uchiha Rei should be invincible by then, right? Besides the Ōtsutsuki, Uchiha Rei couldn't think of anyone who would be her match.
With absolute strength and achievements, becoming Hokage at fourteen seemed quite reasonable. Uchiha Rei planned to strive for it, but Minato Namikaze and Kushina's lives still needed to be preserved.
It wouldn't do for Sasuke's parents to be alive while Naruto had to be an orphan, right? Uchiha Rei wanted to be fair, unlike the Sage of Six Paths, who caused his brothers to fight.
At home, Uchiha Rei felt the abnormality in her body disappear, and her Chakra and physical fitness had also increased a bit, so she knew her Magnet Release Bloodline Limit had completed its evolution.
And when she circulated Magnet Release Chakra, Uchiha Rei even felt she could make metal float. Iron was the easiest; other metals seemed to require integrating into the Magnet Release Chakra.
Rasa controlling Sand Gold was a thankless task, which might be why his strength couldn't compare to the Third Kazekage and his son, Gaara.
Uchiha Rei was a bit confused. Iron was understandable, as iron, cobalt, and nickel are all magnetic. Sand Gold required more Magnet Release Chakra to control, so why did Rasa choose Sand Gold?
Flipping through the Magnet Release training scroll and combining it with her past knowledge of physics, Uchiha Rei finally came up with a somewhat reasonable explanation.
The magnetic domains of these metals are different, and Magnet Release can select one to specifically alter its magnetic domains.
Once selected, controlling that type of metal becomes more agile and simpler. Generally, most people can only remember the magnetic properties of one type of metal.
Rasa likely chose Sand Gold because Sunagakure was short on money. This was the most reasonable reason. Rasa knew he couldn't become Kazekage by Magnet Release alone; his money-making ability would attract more support.
So that's why the Third Kazekage controlled iron sand while the Fourth Kazekage controlled Sand Gold. However, Uchiha Rei always believed that directly controlling metal for attack was a crooked path.
Electromagnetic Cannon was a man's romance, but controlling metal for defense was also a good ability. This was probably why the Magnet Release training scroll chose the path of metal control.
So, what metal is most abundant in nature? That's right, it's aluminum. Due to aluminum's super strong reducing properties, there is almost no elemental aluminum in nature.
However, how could Uchiha Rei, who possesses Magnet Release, Lightning Release, and the Five Thunder Spell, lack the means to prepare elemental aluminum?
But it was too troublesome. Iron sand was still more convenient. However, considering that metal would be used as Electromagnetic Cannon shells, conductivity and melting point had to be considered.
And what could be more suitable than gold's conductivity and high-temperature resistance? It could also make money, so why not? Therefore, choosing Sand Gold was truly a good choice.
Uchiha Rei took out the Sand Gold Rasa had previously compensated her with. Although there were many impurities in this Sand Gold, for Uchiha Rei, who possessed Magnet Release, purifying Sand Gold was simply too easy.
But before that, she first needed to let the Magnet Release Chakra and the Sand Gold's magnetic domains interlink and resonate, to facilitate direct and simple control of Sand Gold in the future.
This process was very simple: just control the Magnet Release Chakra to fuse with the Sand Gold. Once the Magnet Release Chakra remembered the magnetic properties of the Sand Gold, she could be a gold miner in the future.
As the Magnet Release Chakra fused with the Sand Gold, an inexplicable change occurred, and Uchiha Rei felt that controlling the Sand Gold became extremely simple and effortless.
"Now, next, I'll try high-frequency oscillating magnetic field heating to purify the Sand Gold."
Controlling Magnet Release to form a high-frequency oscillating magnetic field area, eddy currents quickly formed in the Sand Gold. Due to the Sand Gold's electrical resistance, it quickly began to glow red.
"Great, it really works, but it's a bit tiring. Does this mean a high-frequency oscillating magnetic field can also heat the human body and other things?"
Uchiha Rei didn't want to heat her own arm, mainly because she wasn't a masochist; why would she roast her own arm for no reason? But she needed a test subject to experiment with its power.
As she continuously maintained the high-frequency magnetic field, the Sand Gold quickly melted into a fluid, with impurities floating on the surface. She used Magnet Release to separate them, and then formed them into fist-sized spiral cones.
Blowing out a blast of cold air with Ice Formation Curses, these spiral cones quickly solidified, turning into golden projectiles.
"Holy cow, I really made pure gold projectiles! Each projectile weighs about ten catties, and according to the Ninja World's gold price, one is fifteen million ryo. Two would be Asuma's bounty."
After casting, the Sand Gold Rasa compensated Uchiha Rei with yielded twenty pure gold cannonballs, weighing approximately one hundred kilograms. One hundred kilograms sounds like a lot, but it's actually not.
It was only slightly larger than a basketball. Although this gold wasn't as valuable as the paper currency she currently possessed, gold was different.
It was golden, making Uchiha Rei a bit reluctant to use it. She just wanted to put it on her bed and roll around on it, although there wasn't enough gold for her to roll around on.
Putting away the other projectiles, she reluctantly kept one gold projectile. Uchiha Rei planned to fire one, but to retrieve the gold projectile, Uchiha Rei also placed many Flying Thunder God Marks on it.
"Now, I shouldn't have to worry about losing it. Although one is only a little over ten million ryo, this is gold! It's not comparable to credit currency like paper money."
Uchiha Rei carried Pakura alone to the Hokage Rock. Standing high, one could see far, and naturally, shoot far.
The principle of the Electromagnetic Cannon is very simple: it just uses the Ampere force. Forming a high-intensity magnetic field can be done with Magnet Release, and making a direct current pass through the gold projectile is also very simple.
Both Lightning Release and the Five Thunder Spell can do it. The way Electromaster directly makes electrons move in a coin is not convenient to control directly with Magnet Release.
Once Magnet Release Chakra is being controlled, using Lightning Release becomes prone to errors. It's more convenient to use Yang Lightning from a spell, as it's closer to natural electricity.
It was simpler to use the Five Thunder Spell, but using the Five Thunder Spell required Uchiha Rei to cup her hands around the gold projectile, which looked as cool as the Great Dao Treasure Bottle Technique.
