Others traveled through Demon Slayer, practiced breathing techniques diligently, and asked for a Sun Lun Sword.
I, a doctor of military industry, started the game and built a standardized arsenal with my backhand.
When Xiazhu still complained that the knife was not fast enough, I handed over the standard Nichirin knife produced on the assembly line: "Try it? If it breaks, we will replace it."
When Worm Pillar was researching a new poison, I sent him a centrifuge and a molecular formula: "The purification efficiency increased by 300%."
When Muzan was laughing wildly in Mugen City, my assembly line was running round the clock, and the ultraviolet searchlight illuminated half of the Demon Slayer Station.
Yuhu stared at the "Nichirin Metal Fragmentation Grenade" I developed, and his artistic conception was shattered: "This... This is not Bushido!"
Seeing the standard swords held by each member of the Demon Slayer team, Shangxuan Zhilu collapsed and screamed: "When did the Nichirin swords get sold in bundles?!"
Later, there was a decisive battle in Infinite City.
Wuhan looked at the people surrounding him, not only the pillars with the breathing method, but also the "technology team" equipped with individual combat systems and carrying ultraviolet emitters on their shoulders.
He went completely crazy: "Uyashiki!! You call this a swordsman duel?!"
And I just pushed up my engineering glasses and pressed the master control switch.
"Mr. Wuhan, times have changed."
"Welcome to the era of industrialized ghost exorcism."
