Tachibana Dessert Shop Underground Laboratory.

Staring at a pair of bloodshot eyes, Hidaka Midori held up his trembling fingers and shook for a long time, and finally gritted his teeth and pressed hard towards the enter key.

"Smack!"

And almost at the moment when Hidaka Midori pressed the button......

"Zilala-smack! Zizizi - crackling bang——! ”

A strong electric sound and the ensuing firecracker-like explosion rang out violently on the body of the armored sound blade connected to the various wiring.

But that didn't scare Hidaka Midori.

I saw her take off the radiation protection glasses on the bridge of her nose, and her eyes full of dark circles stared at the unusually frequent armored sound blade, and her eyes were full of the madness unique to scientific researchers.

That kind of desperate aura is simply daunting.

She is conducting her last experiments with enhanced armor Soundblade.

A...... It will be the "last" experiment in every sense.

Because after this time, if it doesn't work, it will become a benevolent.

So......

How did she get to this point?

This has to start from three days ago.

From the moment he received the task of "liberating and strengthening the armor sound blade", Hidaka Midori knew that this was not an easy task.

You must know that the Armored Sound Blade is not only the strongest crystallization of the Warrior Organization in terms of sonic weapons, but also a weapon whose strength has surpassed the limits of human beings.

So, how easy is it to build on such a foundation and hit a new all-time high in a matter of days?

In normal times, whoever dares to give her a project like this, she dares to pick a child directly.

But who makes this a special time?

Hidaka Green not only did not pick a pick, but also worked hard without sleeping.

However, the armored sound blade was so perfect that it was completely worthy of the title of the highest weapon crystallization in the history of the Warrior Organization, and even if she tried many methods, she could not raise its strength even more......

"Damn!"

It's really not getting any stronger at all!

The mental pressure accumulated from the sleepless high-intensity experiments has long made Hidaka Midori abandon all the ladylike reserves and become extremely irritable.

At this time, there was news from above, saying that the time for Armageddon had arrived, and now it was "Deadline", and if it was not delivered, it would not be needed!

Use...... No...... Above...... Finish......

"Heh, hehehe......"

Hidaka Midori was silent for a moment and smiled.

"Ah, I see......"

With a smile on his face like a collapse, Midori Hidaka put together the most risky plans he could imagine, and decided to give the armored sound blade a big one.

"In that case, then I can't blame it."

Doesn't it say that "if you don't deliver it, you won't need it"?

Doesn't that mean, in other words, "If it's no longer useful, there's no need for it to exist"?

"Na ......"

Smiling sweetly, Hidaka Midori gently stroked the armored sound blade.

"Right, do I understand?"

She looked like she was treating a treasure that she cherished very much, gentle and loving, but as soon as she finished speaking, she began to connect the lines to the body of the armored sound blade, and said as she returned.

"What is perfect...... Is the perfection that can no longer be progressed to really the perfection you want? ”

"You must hate the state you can't get stronger in now, right?"

"Don't worry, I'm here to help you."

"It's just the process, slightly ......"

“…… It hurts a little. ”

“……”

“……”

"Well, there's a little bit of risk."

……

Time comes back to the present.

Midori Hidaka stared closely at the armored sound blade connected by many wires on the experimental table, and the black pupils reflected in the flashing electricity and sparks, and what he heard in his ears was a continuous vibration and explosion.

And then that's when it happened......

"Boom!"

A violent explosion suddenly occurred on the body of the armored sound blade.

Hidaka Midori subconsciously raised his hand to cover his face.

Smoggy.

There was silence all around.

There was no sizzling of electricity, no more sparks.

[Failed......?] ]

Hidaka Midori thought in a daze.

But in the next moment, I heard a series of crisp chirps suddenly resounding in the laboratory, and it was very lively.

Hidaka Midori, who was extremely familiar with the sound gods, reacted immediately.

That's the voice of the gods of the sound!

"Success?"

As soon as she thought of this, she hurriedly waved her palm and stepped forward while dispersing the smoke from the explosion.

The smoke was quickly cleared......

However, it was not because of Hidaka's action, but because there was some invisible fluctuation in the middle of the smoke that spread out in all directions, pushing the smoke away.

This allowed Hidaka Midori to see the scene under the smoke clearly.

The lab table was pitch black, and all the wiring had been destroyed by the previous explosion, except for the armored sound blade, still intact, floating silently in the air, emitting clear sound fluctuations that could be clearly felt just by getting closer, without the need for instruments.

The fluctuations emitted by the armored sound blade can even directly activate the sleeping tone gods, and make the sound gods surround their bodies like arch guardians.

"Succeeded......"

Obviously, it's getting stronger...... And it's not just a little stronger!

Hidaka Midori was stunned for a moment, and immediately clasped his hands and shouted with a very joyful laugh, "I succeeded!" ”

"Yes, congratulations, you made it."

A congratulatory voice came from behind him.

"Thank you......"

Hidaka Midori subconsciously answered, and his expression couldn't help but be stunned.

Wait, why does this sound so familiar?

Then again, is there anyone else here but me?

When did the people come?

When she came back to her senses, she immediately turned around.

"Renzhi!?"

After rubbing his eyes vigorously and confirming that it was not a hallucination, Hidaka Midori immediately showed a surprised and puzzled expression.

"How did you end up here...... Yes! Do you say ......"

Halfway through the conversation, Midori Hidaka suddenly realized something.

"This sword is for you?"

"Yes, that sword was prepared for Uncle Xiang."

It was Hidaka Hitoshi who was standing in front of Hidaka Midori who answered, but Shogo Tokiwa who was standing at the door.

Outside the door is the endless desert of time, the crimson Zio-Liner time train is quietly parked in it, the train hatch is open, and in front of the hatch, Tsukiyomi in a white dress quietly watches over Shogo Tokiwa standing at the door of the laboratory.

I saw Shogo Tokiwa staring at Hidaka Midori and raising his hands to applaud and congratulate her.

"Reforging the strongest sword, a swordsmith who transcends history, and the only strongest demon who can use this strongest sword, is really ...... Best Match！ ”

Shogo Tsukiwa sighed from the bottom of his heart.

"Aunt Little Green, you and Uncle Xiang are really a match made in heaven!"

If it's so straightforward, Hidaka Green is embarrassed to praise it.

Hidaka Hitoshi laughed heartily.

"Hahaha—that's true."

Then, his voice slowed down, and he said softly to Midori Hidaka.

"Midori, you've completed your mission and can rest in peace.

"Get a good night's sleep.

"Next, leave it to me."

"Renzhi ......" is high and green.

"Don't worry!"

Hidaka Hitoshi flipped his palms on the side of his head, pointed vertically forward, and smiled at Hidaka Midori with a familiar gesture.

"Huh~~ I'm a person who has practiced."
