The Heavens: One World, One Superpower

Giyu Tomioka frowned and said, "Our battles with the demons are all in the middle of nowhere, where there's no electricity."

Mist Hashira, Tokito Muichiro, said, "That's right, but there's a problem we need to consider. Battles with demons are often intense, and if we encounter an Upper Moon demon, it's a battle of cataclysmic destruction. In that case, wouldn't these ultraviolet lamps be destroyed and rendered useless?"

The other pillars all thought of these things.

They all felt that while ultraviolet lamps were good, they seemed impractical.

Kagaya Ubuyashiki nodded and said, "Therefore, I have invited you all here today to discuss how to apply ultraviolet lamps in actual combat. One thing has already been resolved: the factory now produces dry cell batteries, which can be used to equip portable ultraviolet lamps."

He clapped his hands again.

Another Demon Slayer Corps swordsman brought in a portable ultraviolet lamp.

In this way, ultraviolet lamps can be used even in field combat environments.

All the pillars are thinking.

How to apply ultraviolet lamps in real combat environments.

The Rock Pillar, Himejima Gyomei, is a strongman, but he cannot see ultraviolet light and therefore cannot make practical judgments.

Sanemi Shinazugawa, the Wind Pillar, kept scratching his head, racking his brains, but still couldn't figure it out.

Flame Pillar Kyojuro Rengoku held the ultraviolet lamp in his hand, clicking his tongue in admiration. He said, "It's incredible that this thing can actually unleash the power of the sun. Now that we have handheld ultraviolet lamps, we can equip a large number of swordsmen with them. From now on, we won't have to worry about demon attacks during night patrols. The ultraviolet lamps may not be very effective for Pillar-level warriors, but for weaker swordsmen, several people forming a group and operating together can be surprisingly effective."

Kagaya Ubuyashiki nodded and said, "That's right. I intend to equip all Demon Slayer Corps swordsmen with handheld ultraviolet lamps. This will be very effective whether they are patrolling at night or dealing with weaker demons. This will definitely reduce casualties and increase the effectiveness of killing demons."

After all, a 30-watt ultraviolet lamp can kill a powerful evil spirit in just ten seconds.

So, if a few more people are holding ultraviolet lamps, even if the wattage isn't that high, they can kill a weak evil spirit in a short time.

This will play a pivotal role in turning the tide of the battle at the grassroots level.

But this is only a battle at the lower levels; only battles at the higher levels can play a fundamental role.

This is also the purpose of Kagaya Ubuyashiki's call for the ten Pillar-level swordsmen to participate in the Pillar Meeting.

Kanae Hanayori couldn't come up with a solution.

Yoshiyuki Tomioka also expressed his helplessness in the face of this.

Obanai Iguro, the Serpent Pillar, frowned, unable to think of how to apply this technique in Pillar-level battles.

After all, the combat power of a Pillar-level being is terrifying, capable of destroying the world.

There wasn't even time to hold up the lamp and shine it on the Upper Moon Demon.

Mist Hashira, Tokito Muichiro, said, "It is indeed difficult to use ultraviolet lamps in Hashira-level battles, unless there is one condition."

All eyes were on Muichiro Tokito.

Muichiro Tokito continued, "Unless we know the location of the Upper Moon demons from the beginning, we can use the daytime to set up ultraviolet lights, and when night falls, we can create a momentary lighting effect. It might not kill the Upper Moon demons, but it can severely damage them."

Everyone's eyes lit up.

But the light quickly dimmed again, for finding out the location of the Upper Moon demons was no easy task.

After all, they have existed for hundreds of years and their whereabouts have always been secretive.
