All of this had happened in the blink of an eye: Hashirama had been knocked unconscious by Kaguya Otsutsuki, and Obito had successfully connected with her space and smuggled the three of them in.
It had all happened so quickly that none of them had even seen Hashirama fly past.
Their bodies turned intangible, as though they had fallen into a swirling void, then slipped through cracks into Kaguya's space.
Just then, Kaguya seemed to sense something and furrowed her brow. Seeing this, Black Zetsu asked, "Mother, what's wrong? Didn't you defeat that little bug? What happened?"
Kaguya shook her head. "It's not that. I feel as though something entered my Origin Sphere Space."
Kaguya had control over the entire space, but that didn't mean she could sense everything happening within it at all times. Take Sasuke in the desert dimension, for example. Kaguya knew where he was, but if he suddenly disappeared, she wouldn't sense it right away.
But there were exceptions. When Obito and the others had slipped through the cracks in Kaguya's space, she had sensed them. It had only lasted an instant, though, like a stone dropping into her space.
She could certainly feel a disturbance, just as a pebble tossed into a lake would send out ripples.
"Could it have been your imagination?" Black Zetsu asked.
"Perhaps." Kaguya thought it over, then nodded and let the matter go.
Kaguya had dismissed it, but Obito and the others had no idea how close they'd come to disaster. They had just walked right through the gates of hell.
Unlike Uchiha Chen, they weren't on the same level as Kaguya, and their breakthrough into her space couldn't go unnoticed. Chen also had the system's help, making it impossible for Kaguya to notice him even if she tried.
Obito,
