Xia Duo disappeared from his figure, tracking the radiation trails left by Drow, and walked through the villa area of Savile Town over and over again, but the traces were incomplete!

The original source of the Drow Assassin could not be found!

The most he could find was in the villa area, as if the Drow Assassin had appeared here out of thin air, but Shado didn't believe much about this possibility.

Thinking that Drow had lived in a dark area for a long time and had not seen the light all year round, he thought of a possibility-

"Maybe it's because of the sun!"

Xia Duo returned to the "art scene" again, and the radiation traces were still very new near the location where Drow was just now, so it was convenient for experimental comparison, he chose a location with the strongest radiation, summoned a ball of light, and only disintegrated it after a while.

There were faint traces of positive energy in the air, and the traces of radiation that Drow had left behind had completely disappeared.

This means that the traces left by Drow can only be discovered that night, and once the night has passed, they will be "refreshed".

This also meant that it was almost impossible to trace the traces of the Drow Assassin before it got dark today.

But again, if traces of radiation were found elsewhere tonight, it would indicate that the Drow Assassin had an accomplice, as his traces were only in the villa area, indicating that he did not leave the villa area after dark.

If there are no accomplices, what about the traces of darkness in other places?

Or, any trace of tomorrow night's appearance would indicate that the Drow Assassin had an accomplice.

However, Shado was not willing to delay until tomorrow night, and the fact that the Drow Assassin did not kill during the day did not mean that he could not kill during the day, although it was unlikely.

If that Drow assassin had an accomplice and was still killing him during the day, even if he could be dealt with in the end, the panic and losses caused would be difficult to eliminate.

Now that the existence of the Drow Assassins is only known to the elves and a very small number of humans, it makes sense to address it as soon as possible.

……

The first thing Shado inspected was the trade area to the east, where there were many outsiders, and if it was slaughtered by the Drow Assassins, the reputation of the Savile Territory would probably be ruined.

Fortunately, after turning around, no traces of radiation were found, but I heard a lot of bad news, and Xia Duo looked a little bad when he left the trade area.

After that, he went to the South and West Regions in turn, and found no traces of radiation, which made Xia Duo feel a little better, at least he didn't have to worry about any more Drow attacks.

As for the news he had just heard in the trade area, since Xia Duo already knew about it, he naturally wouldn't let those guys succeed easily.

……

Returning to the Tower of Time, Xia Duo immediately made his way to the basement floor, where he met the Drow Assassin who was already being held in the cell, and several people were surrounding him.

It was Alberc, Nia, Cecily, and Theore, who had somehow made it here.

Seeing Xia Duo, Nia took the initiative to greet her, "Xia Duo, you came just in time!" We're just talking about a strange item that Drow is carrying, so check it out! ”

"Oh? I'm going to see what can bother you! ”

Xador had just searched for the traces of radiation left by Drow in Savile Town, and although it didn't take much time, it wouldn't be too difficult for a mage with [Identification] to know the effect of an item.

Magic items, in particular, basically can't escape the test of [Identification].

At first, Xia Duo thought that they had found some kind of ordinary item, and it was difficult to determine its purpose, but when he saw the black ball that was clearly emitting a magical aura, Xia Duo realized that things might not be so simple.

So he said, "What is the result of your evaluation?" It can't be completely fruitless, right? ”

The principle of [Identification] is similar to the sandbox simulation in the computer field on the earth, which can simulate the use of magic items from the bottom level, although it is not necessarily possible to know the specific details of the spell, but the function can still be judged in general.

In response to Xia Duo's doubts, Niya said with some irritation: "The identification result is that this black ball can emit faint sound waves in a specific direction, what is the use of this?" But what Drow is most nervous about is this black ball! ”

"You've interrogated him? Didn't he say anything? Xia Duo asked again.

He asked a few words, but he didn't say anything more than filthy invective, and Uncle Alberke told him to shut up for the time being. With that, Nia turned her head and glanced at Drow who was already unconscious in the cell, and her eyes showed extreme disgust.

"So you're just talking about the role of this black ball?"

"That's right!"

"What is the result of the discussion?"

"I think it's some kind of teleportation device, similar to [Wind Signal], that's why Drow is so nervous about this black ball, but Uncle Alberk thinks it's an attack device, because that kind of sound wave is aggressive even if it's weak."

As for Cecily and Theore's point of view, Nia didn't say, but from the expressions of the two of them when Nia spoke, it was obvious that Cecily was on Nia's side, while Theore was more inclined to Alberke's point of view.

After hearing Nia's description of the Black Ball, Chardo couldn't help but think of a possibility, so he offered to identify it himself, and he also asked Alberk to wake up the Drow Assassin.

In this way, even if he can't identify anything, he can use mind spells to get Drow to take the initiative to explain the problem.

Then, Xia Duo directly chose the 5-ring [Identification Technique] of the highest ring level that he could master to cast the spell.

After all, when he was researching the Felder spellbook with Niya, the 5-ring [Identification Technique] was the most used, because he had to check frequently to confirm whether the bridging experiment on the spell book was as expected, and the lower-ring [Identification Technique] had not actually been used many times.

With the completion of the spell, a field that seemed to be a ball of light, but was actually similar to a "sandbox simulation space", instantly appeared, completely enveloping the Black River.

As the light cluster gradually penetrated the black ball, Xia Duo gradually noticed that a "simulated black ball" appeared in the field, and the spell level involved in it did not reach 5 rings, and the spell level involved in this black ball was only up to 3 rings.

After that, Xia Duo easily discovered the excitation port of this black ball, which is a magic item switch in the general sense, and at the same time, he also simulated the excitation in the simulation field.

As Nia said, the black ball emits a beam of flat cone sound waves in a specific direction, and the properties of the sound waves are also reflected in the simulation field, which is in line with Xia Duo's previous guess.

Just as he was about to simulate and synthesize the information many times, a series of shouts suddenly came from the prison on the side, and in addition to the lack of Nase, Xia Duo heard Elven language, dwarven language, and several obviously different styles of language.

The language changed repeatedly, but the content did not repeat in the slightest.

Xia Duo could only understand Elven language, but he also had to say that this Drow was really a fucking language genius, and in the Elf language, Xia Duo could think of, couldn't think of, straightforward, and obscure, and any negative words came out of this Drow's mouth.

Of course, Xia Duo was not polite to him, and turned around and came to the prison, and directly threw over a [Shock], but this trial spell from the [Projection Plane Arcane Empire] was ineffective against this Drow assassin!

He was only slightly stunned, and then the scolding was even a few points higher.
