The scroll contained information not only about Mount Myōboku, but also about Ryūchi Cave and Shikkotsu Forest.
A thousand years ago, the Ninja Cat Clan had tried every possible way to learn Senjutsu. Some powerful ninja cats had even attempted to sneak into the three sacred lands.
Naturally, they'd met grim ends. Those who went to Ryūchi Cave became food. Those who went to Mount Myōboku couldn't even find it; they either died or returned empty-handed. As for Shikkotsu Forest...
The Ninja Cat Clan had once found it. Katsuyu had kindly offered to teach them, but the few who tried had all died, melting into puddles of pus.

That continued until the end of the Warring States Period, when the system of one village per country took shape and shinobi began gathering in large numbers. With ninja cats no longer able to move freely between countries, they finally stopped.
While reading the records about those contract holders, Qingguang noticed something strange.

That clearly violated the principle of an equal contract.
The two parties to a contract could summon each other, but if the one being summoned resisted, they shouldn't be able to summon them.
