Uchiha Kazama had no idea what had happened over there.
Of course, even if he had known, he would not have cared.
Unless the will of the world itself intervened, nothing could threaten him.
Inside the Swordsmith Village.
By now, Kagaya Ubuyashiki had agreed to Uchiha Kazama's proposed trade.
With that settled, Kazama intended to take a good look at the secrets behind the Nichirin Swords.
Soon, Uchiha Kazama arrived at the warehouse.
Looking at the ore piled inside, Uchiha Kazama gently picked up a piece.
"Lord Uchiha, the ore here is only partially processed."
"It needs to be smelted for a long time before it becomes usable metal."
"These special metals are the only materials used to forge Nichirin Swords."
"The Nichirin Swords wielded by the Hashira are all forged from the purest forms of these metals."
"There are also some partially processed materials over there. Purifying this metal requires..."
"Lord Uchiha... what are you doing?!"
The Demon Slayer Corps member stared at Uchiha Kazama in astonishment.
The ore Uchiha Kazama had been holding had already melted.
A ball of flame had also appeared in Uchiha Kazama's hand.
The metal within the ore was slowly being separated out.
"It isn't chakra metal... but I can infuse my chakra into it."
"The effect is much the same as chakra metal."
"And it contains some energy... that energy can even amplify chakra a little..."
As Uchiha Kazama examined the metal in his hand, a look of confirmation appeared on his face.
It was much as he had expected.
As for the forging...
The swordsmiths probably refined these metals, then fused them with some special materials...
Of course, none of that was something Uchiha Kazama needed to worry about.
When the time came, he could hand these metals over to Tenten's family.
