After leaving the Dimensional Store, in just one step, Ei returned to Tenshukaku.
Looking back, there was nothing behind her.
If it weren't for the physics textbook in her hand and the cards she got from opening jars in the Dimensional Store, Ei almost would have thought that the experience just now was just a fleeting dream.
"The Dimensional Store, a miracle outside the world, actually has such a magical place!"
After the trance, she clenched the physics textbook in her hand, and Ei's eyes became firm.
It was hard to come across a miracle.
If she didn't hurry up, she couldn't forgive herself.
She put the physics book very solemnly on the desk.
Ei spread out the cards she had drawn from the jar.
For the time being, she left the food-type cards alone.
The recipe for Fried Tofu was directly printed in her mind.
Although she still couldn't make it, if she recited the Kotodama, she should be able to learn it instantly.
Thinking so, she put the recipe aside.
She looked at the last item she had drawn, which was also the highest-grade item.
—The Core of the Herrscher of Thunder!
Before, because she was listening intently to Takumi's introduction and narration, she did not use this card at that time and did not integrate the Core of the Herrscher of Thunder.
Now, back in her own world, she suddenly remembered this.
Not integrating the Core of the Herrscher of Thunder would definitely affect the learning progress of the cheat codes given by Takumi.
So—
"Crack!"
Ei decisively crushed the Golden Card and let the golden light spots cover her.
After being covered by the golden light spots, a strong aura suddenly erupted from Ei.
Her long braid glowed slightly, which was a symbol of the use of divine power.
At the same time, invisible wind pressure surrounded her.
"Boom—!!!"
The clouds above Tenshukaku, unbeknownst to anyone, had turned completely gloomy.
A powerful thunderstorm swept everything around.
The pitch-black dark clouds fell heavily like lead, resembling the terrifying thunderstorm clouds on Seirai Island, gathering right above Tenshukaku.
The dark clouds were so low that they almost touched the top of the tower.
"Boom—!!!"
"Boom—!!!"
Like an unstoppable thunderstorm, it shook the earth.
The atmosphere on the entire Narukami Island became extremely dignified.
Even the Okuzumeshuu, who were used to hearing thunder, couldn't help shaking their legs in the terrifying and dull thunder, as if they were facing the wrath of the heavens.
Faced with this extreme climate, the staff of Tenshukaku immediately evacuated.
The Okuzumeshuu, who were in charge of protecting the safety of Tenshukaku, and the Shogunate General, Kujou Sara, who came to inquire, immediately went to the hall where the Shogun was located.
"I see the Shogun! Dare I ask, did some scoundrel anger the Shogun?"
"My subordinates will immediately mobilize all troops to punish the gangsters, and hope the Shogun will calm down!"
In Inazuma, thunder and lightning are symbols of the God.
The sudden thunderstorm in front of them could only be the work of the Raiden Shogun.
They subconsciously felt that someone must have angered the Raiden Shogun, leading to the Thunder's wrath.
Kujou Sara's judgment was not wrong.
The thunderstorm in front of them was indeed related to the Electro Archon.
However, it was not out of anger as they thought.
This was only caused by the fusion of the Core of the Herrscher of Thunder, and the power leaking slightly.
Knowing this, Ei didn't say much, but gave a short command.
"Everyone, leave Tenshukaku!"
"Don't come back without my order!"
The Electro Archon's orders cannot be disobeyed.
Even though there were many doubts in their hearts, they still obeyed the order neatly.
"Yes!"
After realizing that all the presences of her subordinates had left, only then did Ei release her own restrictions.
A flash.
Then she came to the roof of the tower.
Holding the Musou Isshin, accepting the baptism of lightning.
She could feel that after accepting the Core of the Herrscher of Thunder, the power of thunder and lightning she held was directly strengthened several times.
Whether in terms of strength or power, the scale had greatly increased.
The power of two homologous forces was superimposed, and the power was incomparable.
She even felt that if she wanted to, she could easily set off a thunderstorm in the Mondstadt region.
"Is this the core strength of the Herrscher of Thunder!"
Ei was full of shock.
I thought that this power could only play a real role after I learned the knowledge provided by Store Manager Takumi.
She did not expect that even if she only integrated the Core of the Herrscher of Thunder, the "slight improvement" obtained was enough to make herself so much stronger.
"No wonder it's a power classified as a Golden level; it's simply too terrifying!"
Only then did Ei really understand the weight of Golden commodities.
And how lucky she was to be able to draw this thing.
"Next time we meet, be sure to thank Store Manager Takumi!"
Crediting the surprise of this power to Takumi, Ei closed her eyes and concentrated on controlling the active Core of the Herrscher of Thunder within her body.
The thunderstorms that covered almost the entire Narukami Island would naturally not escape the eyes of the Guuji of the Grand Narukami Shrine, Yae Miko.
Fortunately, Ei was fusing the power while standing on the top of Tenshukaku.
Although it was far away, Yae Miko could observe the situation of Ei from the shrine at any time without any obstacle, so she was not too worried.
What the two of them didn't know was that the power released by Ei's fusion of the Core of the Herrscher of Thunder this time did not only affect Inazuma.
Mondstadt.
A drunken bard was almost woken up by the lightning flashing in the sky.
"The kagemusha girl from back then has become so strong?"
"Tsk tsk! With this scary posture, I don't even dare to ask her for a drink..."
After muttering a few words, the minstrel in the green cap lay on the table, mumbling something.
The bartender on the side looked at him eagerly, for fear that this guy would escape the bill again.
Liyue.
In front of a storyteller's tea stall.
"At this level of power... is she also looking for a way to break through the predicament?"
A young man dressed in luxurious clothes but with an aura of vicissitudes also looked up at the sky.
"If it is this level of strength, can it resist the erosion that the Heavenly Principles have imposed?"
After seeing this power, the two fishing madmen had other plans in their hearts.
