The projected, false black flames could be sealed with Sealing Jutsu. Only the true Amaterasu flames from hell possessed the traits of burning everything and being indestructible. Nothing could seal them, and they would only slowly disappear after burning everything—even the air—to ash.
Yi Zhengnan, who had made a pact with a demon, recognized them at a glance. In his previous world, there had been people who could summon Amaterasu's flames, but they weren't as powerful as he'd imagined. Even Sasuke's Amaterasu had been stronger.
But the only person Yi Zhengnan had ever seen wield true Amaterasu was Uchiha Chen.
"Not bad. I admit you're worthy of becoming my food." Although Uchiha Chen could summon Amaterasu's black flames, Yi Zhengnan wasn't worried in the slightest.
Who was the thing inside him? A demon. Demons were devils that had crawled out of hell, step by step. With the demon inside him, Amaterasu's black flames might pose a serious threat, but they couldn't burn him to ashes. At most, he'd lose a hand or a foot. He could grow them back after a little time to recover.

"Clang! Clang!"
The katana clashed against Yi Zhengnan's fingertips, sending out dazzling sparks. They scattered and fell to the ground, melting deep little holes into it.

As for everyone else, even experts in Space-Time Ninjutsu like Senju
