Changes in the Shinobi World would never stop because of Uchiha Shunichi's doubts, and Uchiha Shunichi himself had not been paying much attention to changes in the outside world.
Recently, he had been focused on researching the existence of Zero-Tails. As expected of something used by villains, it had no advantages whatsoever aside from its power.
And even in terms of power, it could not compare to the Artificial Tailed Beasts Uchiha Shunichi had cloned.
Of course, the so-called Zero-Tails was still only a half-finished product.
Strictly speaking, Zero-Tails was an existence similar to an evil deity. It grew by absorbing the darkness within people's hearts. The more chaotic the world became, the more energy Zero-Tails could absorb.
Naturally, the current Zero-Tails was severely incomplete and could only absorb dark energy within a range of two or three meters.
If it continued developing, it might truly become an existence comparable to the Tailed Beasts. But something akin to Jashin had never been controllable.
Power that could not be controlled was worse than no power at all! So Uchiha Shunichi decisively drained Zero-Tails of its chakra and allowed it to perish naturally.
As for the Floating City's energy core, Uchiha Shunichi used something else—an Artificial One-Tail!
Creating an Artificial One-Tail was far easier than creating an Artificial Nine-Tails. Uchiha Shunichi had already collected some of One-Tail's chakra.

Just like that... an Artificial One-Tail was easily created.
But precisely because its production method was so simple, One-Tail's strength was absurdly weak. Aside from supplying the Floating City with basic energy, it could not
