Colin and the others didn't have any objection to Xia Duo's behavior of checking his memory, maybe they didn't have the same sense of privacy as Xia Duo, or maybe they thought it was useless for them to refuse.

But in any case, Xia Duo's spell went smoothly, almost perfectly recreating the scene where the four of them met with Tove at that time, although there is a certain subjective element in it, but it is not far from the real situation.

But looking at it, Xia Duo noticed some small movements of Tove, and the other party was not just talking to Colin and the others, but also seemed to be secretly casting spells.

This discovery made Xia Duo very angry, which was simply a provocation, but because it was a scene reproduced with the memories of Colin and others, many details, especially those related to spells, could not be well restored.

Just a few small actions of casting spells do not determine that Tove is casting spells.

But since there are suspicions, it is impossible for Xia Duo to sit idly by.

After stating that the elves might secretly cast spells on them, Colin and the others almost did not hesitate to further examine Xia Duo, and immediately agreed.

"President, what do you think the elves might have done to us?" Jace asked, looking nervous.

"Don't worry, it may just be that some detection mediums have been put on you, or it may affect your mind at that time, what it is, you will only know after checking."

After a brief explanation, Xia Duo began to examine the bodies of Jace and the others one by one, from the outside to the inside, from the present to the past, and even the soul was not spared.

Eventually, it was concluded that the four were indeed affected by some kind of spell, but time had almost erased any traces.

As for the persistent detection medium, Xia Duo did not find it in Colin and the others, perhaps not from the beginning, or perhaps it has been transferred to a corner of the Tower of Time.

At this moment, Xia Duo had a deeper sense of identity with Niya's previous decision to adjust the portal's permissions and restrict the members of the Tower of Time from going out!

Of course, there is communication control inside and outside the Tower of Time, if there is no control, let the communication in and out, then wouldn't it be that the detection spell can also enter and exit freely through the communication spell!

With such an obvious loophole, it is impossible for the original designer of the Tower of Time, the Grand Arcanist of Savile, to leave it, and even the newly appeared magic web background communication, the Tower of Time has specially set up control measures for it.

"Becoming an Immortal"

Although the old and new communication controls of the Tower of Time cannot determine the information of the communicator on the other end of the communication, nor can they know the content of the communication, the communicators within the Tower of Time are counted as one by one, and all of them are recorded.

Xia Duo asked Taling and learned that in the past few days, there have been a total of sixteen internal and external communications within the Tower of Time, all of which are within the normal legal communication authority, and there is not a single illegal communication without permission.

This means that either the sixteen communications that were able to identify each of the correspondents were problematic, or Tove's discovery medium had not yet been revealed.

The premise of this speculation, of course, is that Tove did place a movable detection medium on Colin and the others.

But in any case, an all-round routine "sanitization" inside the Tower of Time is inevitable.

Generally, this level of "sanitizing program" may not be started once in a year or two, and the maintenance cost of starting once is at least calculated in tens of thousands of gold coins.

If this had been placed in the past, Xia Duo might have thought about it, but after making a profit from the mass production of magic items, and the fact that he had just touched more than 100,000 Arcane crystals recently, he made this decision now without even blinking an eye.

……

After making sure that Colin and the others did not have Tove's backhand, Xia Duo asked them to go back first, and of course the refresher class that did not exist was also arranged for them.

After that, he informed Niya to activate the full sanitizing procedure of the Tower of Time.

And Niya's actions were also very fast, and after almost no waiting, Xia Duo, who had just finished the arraignment, received a notice from Taling-

"Alert, the Tower of Time is about to start a comprehensive sanitizing procedure, in order to avoid accidents, all members immediately stop their work and return to their respective residences, this sanitizing procedure will last 120 minutes."

Immediately afterward, Xia Duo heard a series of sounds of functional facilities being closed-

"The Arcane Garden is closed—

"The library is closed—

"The public floor is enclosed—

“……”

Seeing this, Xia Duo immediately teleported to Niya's study on the top floor, Niya was still here at the moment, as if she was waiting for Xia Duo to come back, as soon as she saw Xia Duo, she immediately asked worriedly:

"What's going on over there, Colin? Is it Tove who does what? ”

Xia Duo nodded and explained: "Tove may have put a detection medium on Colin and them, I can find it, anyway, let's sanitize it first, anyway, the Tower of Time is not short of that little money now." ”

As he was speaking, Xia Duo felt a huge range of spell suppression field appear out of thin air, and the projection window that was still lit next to the two of them disappeared in an instant.

Not only the projection window, but even the various magical items on Xia Duo and Niya have lost all their magical aura at this moment.

Fortunately, the spell suppression field comes and goes quickly, if you stay in the suppression field of this intensity for a long time, one of the magic items on Xia Duo's body counts as one, and it is estimated that none of them will last long.

Of course, none of the various practical spells blessed by Xia Duo survived after the Pacification Field passed.

Fortunately, he was inside the Tower of Time, otherwise even if there were a few more calming fields in the future, Xia Duo would immediately bless himself with at least one evasive detection spell.

Without this spell on your body, you would be too insecure.

……

After the spell suppression field, Xia Duo then sensed several exploration fields involving different levels sweeping, and then it was the spell suppression field.

This cycle has been repeated many times, during which various spells to remove magic or non-magic anomalies have been counted to complete a comprehensive set of sanitizing procedures.

The total duration is 120 minutes, which is Taling's estimate.

During the sanitizing period, Xia Duo stayed in the top floor study with Nia, and the projection window was temporarily unusable, so the two made tea and chatted.

By the time the sanitization was completed, the projection window was also lit up again, but the perspective of the central square of Savile Town set by Nia before had been reset and turned blank.

However, Xia Duo was in no mood to reset the perspective of the projection window at the moment, and after taking the last sip of tea in the teacup, he stood up and said to Nia:

"I'll go meet Tove for a while, no matter what, the cost of a complete sanitization of the Tower of Time must be credited to her account!"

"I'll be here to watch you and be there for support."

Xia Duo nodded, didn't say anything more, everything was silent, he took one last look at Nia, and then resolutely teleported to the public level, ready to go to Savile Town through the portal.
