With a bang, like a thunderclap in the silent study, Xiao Ru's head slammed into the pillar behind him, and his eyes went straight to Venus. The pull ring couldn't withstand Xiaoru's great force, and fell off from the dark grid, and was hanging alone on Xiaoru's fingers at the moment.

Xiao Ru stood up slowly with her head covered, the back of her head hurting hotly. Her head is also pitiful, she only hit her forehead with a big bag two days ago, and today she almost bleeds from the back of her head, which is really unlucky.

But Xiao so moment's attention is not on the head, this kind of secret grid can't be locked, and she just tried, without immortal protection, it stands to reason that opening it is a breeze. She remembers that when she was the size of a doll, she could easily open it.

The pale moonlight shone on Xiao Ru's face, reflecting a slight pale and weak taste, and this strange dark grid happened to be hidden in the shadows, and no matter how Xiao Ru changed his position, he couldn't see it clearly.

"Did you misremember?" Maybe she was in the wrong place, a long time in the future, maybe she remembered it wrong, this book building is similar everywhere, maybe this dark grid is not the one she remembers.

Xiao Ru looked around again, the structure of the study was neat and uniform, and there were many dark grids like this, which should be in another place. The moonlight shines through the bookshelves on the ground in mottled and square shadows, as small as rows rummaging through them, to the westernmost side of the library. In the same place, Xiao Ru touched a dark grid again, and sure enough, she remembered the wrong location. She calmed down, her fingers straining slightly. The lattice was sunk into a piece, and the sound of the mechanism turning came from the quiet study, which was obviously inaudible, but Xiao Ru felt extremely harsh. The mechanism jammed halfway through the spin, and what she wanted was half-hidden in the depths of the dark grid, reflecting the moonlight, and she could barely see a book lying quietly in the dark grid.

Xiaoru stretched out a few fingers to pull the book, the gap was too small, and he could only barely touch the corner of the book, and he couldn't use his strength. Brute force can't work, it's always good to pinch a fairy technique, but Xiao Ru's fairy power just touched the book, and disappeared without a trace.

Strange! How so?

The clouds floated by, the moonlight was bright and dark, as small as a thief's heart, and his heart was pounding.

"Squeak-" It seems to be the sound of someone pushing the window open, and it should be in the corner of the study's side.

"Squeak-" again, and the window that had been pushed open should have been carefully closed again.

Xiao Ru's shadow pulled out a long strip on the ground, merging with the bookshelf. "Damn it!" Xiao Ru secretly screamed in his heart, if that person came from the east side, he would definitely see himself, although he didn't know who it was, but it was better to go first. Xiao Ru tried one last time, and the book was still lying in the dark compartment, not moving, and his fingers were covered with dust.

The footsteps coming from the east were very soft, but they could be faintly heard, and they were not far from Xiaoru's side.

It was too late to close the dark compartment again, Xiao Ru silently recited the spell a few times in her heart, gradually disappeared in the air, and quietly retreated to a slightly farther place to observe the uninvited guests in the study. Her stealth technique is better than the transformation technique, but the traces of the immortal magic of this stealth technique are smelled by people with higher immortal power than her, and she will be undoubtedly exposed.

But she is just curious, this person is obviously also here for this book, maybe they have the same purpose, they both want to save Lao Wutong, but in this valley except for the third sister, who else can know about this? The third sister, as the valley owner, wants to take a book, why bother sneaking?

Dressed in a night suit, he is slender and straight, slightly emaciated, and is a man. He may have thought that there was no one in this study, and he was obviously doing something sneaky, but he was as upright as walking in the front hall of his house.

Obviously he was already invisible, but Xiao Ru was always a little worried, and walked to the corner again, hiding his entire body behind the bookshelf, and quietly observing the man.
