Tia didn't know about these twists and turns, but Serena's precautions against her didn't seem strange to her.

In such a small race, there are definitely not many elderly goblins who can wear veils, and she is not among the "acquaintances" known to the administrator lady, so it is not surprising that she will be noticed.

Looking at the books she had randomly pulled from the shelves, Tia kept an eye on Serena as she mimicked the way an elderly goblin reads a book.

Soon, after a few minutes, she summed up the approximate frequency with which the lady was observing herself.

As an experienced observer, Serena couldn't possibly put all her eggs in the same basket, and Tia was suspicious, but it was easy to get caught up staring at her and ignoring the other goblins.

Therefore, although she has been observing Tia for the longest time, she is also paying attention to other goblins.

In other words, there is a time gap between her observations of Tia.

Tia roughly calculated the time, which was about eight seconds.

During these eight seconds, Serena will turn her gaze to the other elves, and after confirming that no suspicious behavior has occurred, she will shift back to Tia's body.

After observing for a few minutes and determining the accuracy of her time calculation, Tia no longer wasted her time on it.

Through the veil, she began to look at the environment of the library, her eyes turned from left to right, and then from top to bottom.

According to the information that Messi once revealed, the library is the most important inheritance place of the Tabro goblins, and all the historical materials that still exist are kept here.

These materials are divided into two categories.

One is the ordinary information that can see the light, and the other is the secret of the race that is equivalent to the secret history.

The two types of data are also treated in very different ways.

On the surface, there are some ordinary materials with a very low level of secrecy, and the most important materials are placed in a more secret place and sealed.

Under the gauze covering her face, Tia's eyes moved, and the Eye of Truth opened silently.

The area of the library is not too large, at least Tia can still see the whole library when she sits in her position and rotates around.

But no matter how small a place is, Tia who is fixed in one position can't use his eyes to rotate 360 degrees to make a panoramic scan.

The secret room is out of sight, pure luck.

After glancing around in her line of sight, Tia frowned.

Not in sight in their own direction.

With a sigh in her heart, she slowly got up with her waist bent, shuffled to another position and sat down, and a sense of tranquility filled her body.

After carefully observing Tia's sudden actions, Serena didn't notice anything unusual, and could only think that the other party had some unforgettable memories in this position a long time ago.

Giving her a suspicious look, Serena faithfully followed the eight-second theory and looked away.

And Tia, who changed direction, opened the Eye of Truth again.

After scanning it, she froze and focused on a spot on the ground.

Got it.
