In the Sand Village, the clones are everywhere, and the Arkham game begins

Chapter 212 Improvement

Chapter 212 Improvement
The smile on Luther's face didn't last long.

Because not only did he see that a corner of his own building was destroyed in the battle, he also saw that the heavy particle accelerator that he had spent a lot of money and effort to build seemed to be scrapped due to energy overload.

This has nothing to do with Qingshui for now.

Now Shimizu is using the intelligence network of the Assassin's League to prepare assassination plans against those politicians who want to kill him without leaving any traces or evidence.

This is the ninja's old job.

……

Demons destroy the world.

In the long corridor, doors were opened one after another.

In the vast and yet bizarrely shaped three-dimensional ancient city, orange-red lights are lit up.

"Mingnu, why did you call me here? Have you found that person?"

Muzan, wearing a geisha costume, stood by the lotus pond and asked Mingnu who was crawling behind him.

Mingnu raised her head, and the word "Lu" appeared on the only eyeball on her face.

After the death of Douma, the Upper Rank Two, and Gyokutsuchi, the Upper Rank Five, Muzan naturally had to select demons with Upper Rank qualifications from among the remaining demons to fill their places.

And Naruto is the new Upper Six.

"The pillar that inherited the breathing technique has not been found yet, but... I have made a new discovery about my scattered sub-bodies. I think you, Master Muzan, will be very interested, because this is enough to cause irreparable harm to Ubuyashiki."

Mingnu knelt on the ground again, holding the pipa and spoke to Muzan.

She was referring to the clear water.

Because the name of Tsugumi Yoriichi is a taboo in Muzan, no one except Kurohei Shimei dares to call out that name, so she uses the name of the ancestor of the breathing method as a pseudonym.

When Muzan saw the memory of Douma before his death, Yoshiichi Ichishiki who looked exactly like Yoshiichi Tsugakuin, he was almost scared to death on the spot and wished he could hide in the Infinite Castle for the remaining decades.

But after receiving the memories, Muzan finally breathed a sigh of relief.

It turned out that Tsugikoku Yoshiichi, who had been dismembered by Kokushibo's sword, did not crawl out of the coffin, but was still against him.

Through the Yoriichi Shiki, Muzan firmly believed that Shimizu became powerful because he found the backup plan left by Yoriichi Tsugikuni three hundred years later, and was able to kill Upper Rank Two and Upper Rank Five in one night by himself.

After all, if we count the pillars of the Demon Slayer Corps, the person who can do this, apart from Tsugakuni Yoriichi himself, may be Tsugakuni Iwaki, who once served as the Moon Pillar - he is the strongest among the first generation swordsmen except for Yoriichi himself.

The remaining first-generation swordsmen also have a chance to defeat the Upper Ranks, but they are not certain to win, let alone kill two directly.

Muzan looked at Mingnu and began to read her memory.

"I see. You did a great job. This is indeed a good opportunity to completely destroy Ubuyashiki."

A cruel smile appeared on the face of the female-dressed Muzan, and he licked the corner of his mouth with his tongue.

"Call Kokushibo and let him do it. Don't be in a hurry to kill him. I want to have a taste of something new."

"Yes... Lord Muzan."

Mingnu lowered her eyes and stretched out her slender fingers to play the pipa.

……

New Knife Forging Village.

A slender, bright red sun blade gradually cooled down.

"The duration is still a bit short. Even if you, Lord Lizhu, have improved the battery, the one-time endurance will still not exceed three minutes." Tetsukanemori Kozo looked at the cooling red sword and scratched his head in annoyance.

"It's okay. As long as we make the battery size of fluorescent flashlights the same, and let swordsmen carry a few more before the battle, we can keep the red sword and flashlight usable for as long as possible."

Qingshui was quite satisfied.

Improving zinc-iron batteries to nickel-cadmium batteries has a significant increase in cost, but the effect is still good.

The main reason is that the Ubuyashiki family is very rich and have accumulated wealth for hundreds of years. Even if most of it was used to fight against demons, they are still rich enough to rival a country, so this amount of money is nothing.

Not to mention that in order to exterminate demons, he would not hesitate even if it meant exhausting all the wealth of the Umayashiki clan.

"So now, there is one last problem left to be solved."

Iron Cave Forest Steel Hidden Road:

"That is the Insect Pillar's Nichirin Sword. We cannot modify it. She uses the wisteria flower toxin in the blade to kill demons. But once the blade is heated to a high temperature, the plant toxins inside will quickly deteriorate and necrotize, and will no longer be able to cause effective damage to demons."

Qingshui raised his eyebrows slightly.

Shinobu Kocho first practiced Flower Breathing with her sister Kanae Kocho, but Shinobu Kocho was born with less strength and was unable to unleash the power of Flower Breathing. When facing some stronger demons, she would cut off the demons' heads. Then she took an unconventional approach and created the Insect Breathing school based on Flower Breathing, using high-speed stabbing combined with poison to fight.

If she cannot use the wisteria flower poison, Shinobu Kocho's combat effectiveness will be greatly reduced.

"It's not a big problem actually. It just requires some changes to the structure of the Shinobi's Nichirin Sword."

Qingshui took out a branch and started drawing on the ground.

"The front end is still a sharp blade suitable for stabbing. In the past, ninjas used this end to pierce the body of the demon and then inject the wisteria flower toxin. Now, an insulation layer is added under the blade. A thin branch is separated from the lower end of the insulation layer to serve as a needle for injecting toxin. When the power is turned on, only the front end of the blade is heated to become a red blade, which enhances the piercing power against demons."

While the two were discussing, a hermit covered in a brown robe uniform came jogging over, panting.

"Lord Lizhu! Our lord is critically ill and requires us to leave to hold a meeting!"

Qingshui looked up in surprise.

This is wrong!
According to the timeline, Zenitsu and Kanao have not yet participated in the final selection of Fujikiyama, but Tanjiro has passed it in advance. There is still a year and a half before Ubuyashiki Yoshiya dies of illness.

Why is it so far in advance?

"I see."

Qingshui nodded slightly at the hermit, then said goodbye to Tiexue Mori Gangzang and left immediately.

With Shimizu's walking speed, it was almost the fastest to reach the Ubuyashiki residence.

Also arriving at about the same time as him were Meimijima Yukimei and Tokito Muichiro.

The two of them are the closest.

"My lord!"

Tokito Muichiro touched Ubuyashiki Yoshiya's hand with a look of reluctance.

Ubuyashiki Yoya, who was lying on the bed, opened his eyes and said weakly:

"Wuyilang, Xingming, Qingshui, you are here..."

"Namo Amitabha, please have a good rest, my lord."

Beimingyu Xingming clasped his hands together and chanted the Buddha's name.
