"Eh? Since when did Haku become this strong?"
While observing Sasuke, Hyuga Kagami discovered that Haku, who was fighting him, had actually suppressed both Sasuke and Gamabunta single-handedly. If Haku's attacks had not been somewhat hesitant and lacking in sharp decisiveness, Sasuke's situation would have been even worse.
Logically, Sasuke and Gamabunta, a pair capable of using combined fire-and-oil ninjutsu, should not have feared Haku's Ice Release, much less been suppressed by him alone. Hyuga Kagami immediately shifted his attention to Haku, who was darting through the ice mirrors.
Very quickly, Hyuga Kagami noticed an exceptionally powerful natural energy radiating from Haku. Not only that, Haku's face bore strange eye shadow markings similar to those of Sage Mode.
"Senjutsu?"
Hyuga Kagami froze when he noticed this.
He knew perfectly well that Haku, serving under Orochimaru, would certainly be stronger than he had been under Zabuza in the original timeline. Yet he had never expected Haku to master Senjutsu.
Moreover, the altered area on Haku's face was very small. Unlike Jiraiya, whose body underwent extensive frog-like transformation in Sage Mode.
One had to know that the more obvious the body's transformation in Sage Mode, the greater the body's rejection of natural energy. Conversely, if the transformation was faint, it meant one had a strong ability to control natural energy.

"Could Orochimaru have made some progress with Senjutsu?"
Remembering how Orochimaru had used his own cellular tissue in the original timeline to create a group of artificial humans born with the ability to absorb natural energy and enter a special kind of Sage Mode,
