Black Oil!
Massive amounts of Black Oil poured down like a torrential downpour.
Whoosh!!!
The Black Oil ignited the moment it touched the flames on the metal sheets, making the five airships seem as though they were scattering Flame Waterfalls across the earth.
What the five airships had been transporting was Black Oil.
The refined kind, at that.
The oil used for Incendiary Bombs!
Since this weapon had been used many times, leaks were inevitable. It was no surprise that quite a few factions had developed technology to refine Black Oil.
Amegakure was one such faction, with both the means and the need to develop it.
Did you remember what was there?
The Black Market!
The Shinobi World's largest Black Oil and bird-dropping trading Black Market.
Its scale was astonishing, second only to Blazing Sun Country, and it even surpassed the Allied Forces' openly reported extraction volume.
Thanks to those two industries, life in the Rain Country was currently far too comfortable.
If Nagato had not been obsessed with gathering the Ten-Tails and making the entire Shinobi World feel pain so they would understand the value of peace, he might already have been satisfied.
The Rain Country only had several million people, and nearly a million of them were involved with Black Oil and bird droppings.
Transportation, refining, effects... every link in the chain could support countless people. It was not an exaggeration to say that the Black Market, as a pillar industry, supported an entire country.
With so much Black Oil, they had the conditions to build refining plants. Once refined, it could also be sold at a far higher price.
So, it was not strange at all for Akatsuki to obtain so much refined Black Oil to use as a weapon.
They simply could not expose the relationship
