Sure enough...
The dim yellow tones, the walls built from pipes, the enormous sealing gate, and the huge sealing formula upon it—nothing in the Sealed Space had changed much. The only difference was the boy beneath the sealing formula, staring intently at that vast and complex Sealing Jutsu Formula while inwardly thinking, Sure enough. Countless streams of information seemed to flash through his eyes.
After taking Higan, Chiba's vision had gone dark. By the time light entered his eyes again, he was already here.
The Sealed Space he had been entering and leaving frequently lately.
He was now examining the portions of that enormous and complex Sealing Jutsu Formula that he needed to see—the vast remaining structures within that one-tenth of the formula.

In just this short time, he had already looked through what had once taken him several hours to study. More importantly, he had finished examining it with comprehension.
