The Core of the Herrscher is strong.
"But if you don't have enough physics knowledge, the effect of its use is estimated to be not much different from the power of Thunder."
Ei has lived for thousands of years.
But she mostly honed her martial arts.
It was obviously impossible for her to grasp the Core of the Herrscher of Thunder directly and completely.
So—
"You'd better study physics first!"
Takumi thoughtfully took out a textbook on basic physics from the nine-year compulsory education curriculum and gave it to Ei.
"Leave aside quantum mechanics and molecular physics for the time being. You should first familiarize yourself with the basic properties of electromagnetic fields."
Ei had zero basic understanding of science.
She could not be too ambitious; she had to learn step by step from the most basic level.
She herself was the wielder of the power of Thunder.
She was very familiar with the nature of thunder and lightning.
Coupled with the Purple Skill Card [Railgun], which also came with some related knowledge, Ei's learning speed should not be slow.
It shouldn't take more than a few days to initially grasp the Core of the Herrscher of Thunder.
As for further control, or even fully utilizing the power of the Herrscher Core, it depended on her own learning speed and understanding.
"Yes! Thank you very much, Store Manager Takumi!"
Holding the textbook Takumi handed her, Ei's purple pupils were filled with gratitude.
She didn't expect Takumi to be so kind to her.
Not only did he give her the opportunity to save her sister, but he also patiently explained the power of the commodities and gave her free teaching materials to teach her how to master the power.
He was simply a rare, kind person in this world!
"You're welcome, Miss Ei."
Takumi smiled slightly.
"To share the worries and solve problems for customers is the purpose of our Dimensional Store."
Of course, solving problems was definitely not free.
Casting a long line to catch a big fish was the basic operation of a businessman.
Ei was not unaware of this.
But she was still very grateful to Takumi, and she was also very touched by Takumi's kind and seemingly selfless help.
So—
"If it's Store Manager Takumi, just call me by my name," Ei said.
In Inazuma, calling someone by their given name was something that only friends did.
There was no doubt that she already had a fair degree of trust in Takumi.
Naturally, Takumi would not reject this way of expressing intimacy.
"No problem, you can also call me by my name, Takumi, or Store Manager."
After getting closer to each other, Ei held the book in her hand, looked at the jar that had been opened, and suddenly remembered something.
"By the way, Takumi... Store Manager, I want to ask, how can I get more Origin Points?"
Having sold all the templates of her own strength, the 200,000 Origin Points she received in exchange had been used up.
Although the high-grade Gold quality Herrscher Core of Thunder was drawn and her power had been greatly enhanced, the most critical issue, and the one that Ei wanted to solve the most, had seen no progress yet.
She hadn't drawn any items or skills that could revive her sister.
Only by opening jars slowly in the future would it be possible to achieve her wish.
To get enough jars, the most important thing was to get enough Origin Points.
Thinking of this, Ei began to worry a little.
Her own power template had been sold, and there was no way to sell it a second time.
Where would the next Origin Points come from?
Hearing this question, Takumi, who was already prepared, immediately spoke.
"As I said before, in addition to using one's own power to exchange for Origin Points, items containing energy, concepts, and rules can also be exchanged."
"However, in general, only items that contain a lot of energy are valuable. Things like the Elemental Sigils in your world are worthless."
Hearing Takumi's detailed explanation, Ei immediately eliminated options such as the Electroculus in her mind.
The Musou Isshin was a weapon that relied on her own consciousness, which was almost impossible to sell.
Other than that, what else was there of value?
After thinking for a while, Ei's eyes lit up, suddenly remembering something.
"That's right, Store Manager! Do you think a Gnosis is valuable?"
Containing energy, concepts, rules... Wasn't this exactly a Gnosis?
It just so happened that after she created the Raiden Shogun, the Gnosis had long been abandoned by her and was useless.
If she could exchange this waste product for Origin Points, it would be a profit.
"This is indeed worth a lot of Origin Points."
Takumi nodded.
Although it was said that a Gnosis was not a necessary item for a Demon God.
But as a device that could absorb faith and strengthen the power of a Demon God, its value should not be low.
Otherwise, the Tsaritsa would not think that she was qualified to challenge the Heavenly Principles by gathering the Seven Gnoses.
Hearing Takumi's affirmation, Ei's eyes immediately lit up.
"Great!"
Every additional Origin Point could capture the hope of saving her sister.
Thinking like this, a bold idea suddenly popped into her mind.
If her own Gnosis could be worth a lot of Origin Points, what about the other Archons'?
If she could get the Gnoses of the other Archons, could she get a few more jars?
Thinking of this, she couldn't help asking Takumi.
"Store Manager, if there are multiple repetitions of a Gnosis, will the recycling price change?"
She keenly noticed that the Dimensional Store seemed to care more about the information of the product template.
That is to say, if the exact same thing was recycled for the second time, the price might be greatly reduced.
In this case, if the Dimensional Store treated the Gnoses of different Archons as the same commodity, collecting other Gnoses would be a bit of a loss.
"..."
Hearing Ei's question, Takumi was silent for a moment.
Good guy, what was Ei going to do?
Multiple Gnoses? Duplicates?
The Tsaritsa hadn't started collecting the Gnoses yet, but was Ei ready to start?
Thinking of the original plot, where the Tsaritsa collected the Gnoses, now becoming the Raiden Shogun collecting the Gnoses, Takumi felt a phantom ache in his teeth.
It was nothing to have a big change in the plot, and it was impossible for Ei, who had been in contact with him, to continue on the previous route.
But when he thought that at a certain moment in the future, when the Tsaritsa received the news on her throne that a Gnosis had been snatched away by the Raiden Shogun in advance, Takumi wanted to laugh a little.
However, jokes aside, Takumi still had his professional ethics.
So, he answered immediately.
"If it is a Gnosis of the same attribute, the price of the second recycling will indeed be greatly reduced."
"But if it is a Gnosis with different attributes, the recycling price will not be impacted much."
That is to say...
The Electro Archon, Anemo Archon, Geo Archon, Dendro Archon... all together could sell for a lot of Origin Points.
Realizing this, Ei nodded heavily.
"I understand!"
