Zheng Xiu knew Xie Luohe yearned to "return to normal."
But neither Xie Luohe nor Zheng Xiu knew what the so-called secret to "returning to normal," hidden in Nie Gong's Treasure Vault, actually was.
Before his death, the Former Imperial Tutor had only said one phrase: "the secret to returning to normal."
But as for this "secret," whether it was a secret manual or an object, no one knew.
At the foot of Hidden Sword Mountain, Zheng Xiu had met Fan Yao—a pitiful man who was a Monk yet not a Monk, who had been born into this World in the Painting and wasted forty years of his life here—and he had spoken of this secret as well.
From his words, Zheng Xiu inferred that there was an "exit" in Nie Gong's Treasure Vault.
If the true nature of "returning to normal" was an "exit," then everything would make sense.
