The smile on Luther's face didn't last long.
Because he not only saw a corner of his own building destroyed in the battle, but also saw the heavy particle accelerator he had spent heavily on and painstakingly built seemed to be scrapped due to energy overload.
This has nothing to do with Shimizu for the time being.
Now Shimizu is using the Assassin Alliance's intelligence network to prepare assassination plans against those politicians who want to kill him, without leaving any traces or handles.
This is the ninja's old business.

Demon Slayer World.
In the long corridor, one door after another was opened in succession.
In the empty and vast, yet strangely shaped three-dimensional ancient city, orange lights lit up one after another.
“Nakime, what is the matter for summoning me here? Have you found that person yet?”
“The Pillar who obtained the inheritance of the originator of Breathing Styles has not been found yet, but… my sub-bodies scattered outside have made a new discovery. I think, Muzan-sama, you will definitely be very interested, because this is enough to bring irreparable harm to the Ubuyashiki.”
Nakime knelt on the ground again, holding the biwa and speaking to Muzan.
The person she was referring to was Shimizu.
Because Yoriichi Tsugikuni's name is a taboo for Muzan, and no one except Kokushibo dares to call out that name actively, so she used the originator of Breathing Styles as a substitute.
Back then, through Doma's memories before his death, Muzan saw Yoriichi Type Zero, who looked exactly like Yoriichi Tsugikuni, and was almost scared to pee on the spot, wishing he could hide in the Infinity Castle for the rest of his decades.
But after receiving the memory, Muzan finally breathed a sigh of relief.
It turned out that Yoriichi Tsugikuni, who had been dismembered by Kokushibo with a single sword, did not crawl out of the coffin, but was still opposing him.
Through Yoriichi Type Zero, Muzan very decisively believed that Shimizu had found the contingency left by Yoriichi Tsugikuni three hundred years later, and that was why he had become so strong, able to consecutively kill Upper Moon Two and Upper Moon Five in one night with his own strength.
After all, counting the Pillars of the Demon Slayer Corps throughout the generations, the only person who could do this, apart from Yoriichi Tsugikuni himself, might be Kokushibo, who once served as the Moon Pillar—he was the strongest among the first generation of swordsmen besides Yoriichi himself.
The remaining first-generation swordsmen also had a chance to defeat the Upper Moons, but they were not necessarily guaranteed to win, let alone directly kill two of them.
Muzan looked at Nakime and began to read her memory.
“I see, you have done well. This is indeed a good opportunity to completely destroy the Ubuyashiki.”
A cruel smile appeared on the face of Muzan in women's clothing, and he stuck out his tongue and licked the corner of his mouth.
“Call Kokushibo here. Let him take action, but don't be in a hurry to kill him so quickly. I want to taste something fresh.”
“Yes… Muzan-sama.”
Nakime lowered her eyes, stretched out her slender fingers, and plucked the biwa.

New Swordsmith Village.
A slender, red Nichirin blade gradually cooled down.
“The duration is still a bit short. Even if Pillar-sama, you have improved the battery, the one-time battery life will still not exceed three minutes.”
Kanamori Kotetsu looked at the cooled crimson blade and scratched his head in frustration.
“It's okay. As long as the battery size of the flashlight is unified to the same size, and the swordsmen carry a few more before the battle, the use time of the crimson blade and the flashlight can be maintained for as long as possible.”
Shimizu was still quite satisfied.
Improving the zinc-iron battery to a nickel-cadmium battery, although the cost has increased significantly, the effect is not bad.
The main reason is that the Ubuyashiki family is very rich. They have accumulated wealth for hundreds of years. Even if most of it is used in the fight against demons, it can still be called rich enough to rival a country. This amount of money is nothing.
Not to mention, for the sake of the great plan of exterminating demons, he would not hesitate to exhaust all the wealth of the Ubuyashiki family.
“So now, there is still one last problem that has not been resolved.”
Kanamori Kotetsu said:
“That is Insect Pillar-sama's Nichirin blade. We cannot modify it. She uses wisteria poison from within the blade to kill demons, but once the blade is heated to a high temperature, the plant toxins inside will quickly deteriorate and die, making it impossible to cause effective damage to demons.”
Shimizu raised his eyebrows slightly.
Shinobu Kocho originally practiced the Flower Breathing with her sister Kanae Kocho, but Shinobu Kocho was born with less strength and could not exert the power of the Flower Breathing. When facing some stronger demons, she could not cut off the demon's head, so she took a different approach and re-created the Insect Breathing style based on the Flower Breathing, using high-speed stabs in conjunction with poison to fight.
No mistake, one shot, one hit, one content, one look!
If she cannot use wisteria poison, Shinobu Kocho's combat power will be greatly reduced instead.
“Actually, it's not a very big problem, it's just necessary to slightly change the structure of Shinobu's Nichirin blade.”
Shimizu took out a branch and drew on the ground.
“The front end is still a sharp blade suitable for stabbing. In the past, Shinobu used this end to stab into the demon's body and then inject wisteria poison. Now, a heat-insulating layer is added below the blade, and a thin branch is separated from the lower end of the heat-insulating layer to serve as a needle for injecting poison. When the power is turned on, only the front end of the blade is heated to become a crimson blade, enhancing the piercing power against demons.”
Just as the two were discussing, a Kakushi, whose whole body was covered in a brown robe uniform, trotted over, panting.
“Pillar-sama! Master is critically ill and requests that Pillar Meeting be held!”
Shimizu raised his head in surprise.
This is not right!
According to the timeline, Zenitsu and Kanao have not yet participated in the final selection on Fujikasane Mountain. Tanjirou has passed it early, but there is still a year and a half before Ubuyashiki Kagaya becomes seriously ill and dies.
Why is it so early?
“I understand.”
Shimizu nodded slightly to the Kakushi, then said goodbye to Kanamori Kotetsu and left in a flash.
With Shimizu's speed, he was almost the fastest to arrive at the Ubuyashiki residence.
Himejima Gyoumei and Tokito Muichirou arrived at about the same time as him.
The two were the closest in location.
“Master!”
Tokito Muichirou touched Ubuyashiki Kagaya's hand, looking reluctant.
Ubuyashiki Kagaya, lying on the bed, opened his eyes and said weakly:
“Muichirou, Gyoumei, Shimizu, you have come…”
“Namu Amida Butsu, please rest well, Master.”
Himejima Gyoumei put his palms together and chanted the Buddha's name.
Shimizu stepped forward, reached out and pressed on Ubuyashiki Kagaya's body, his palm lit up with a faint green light.
Ubuyashiki Kagaya was usually very nice to him, and he was doing his best to help him realize what he wanted or the plans he proposed.
