Chapter 646: Check, black ball

Xia Duo disappeared and traced the traces of radiation left by Drow, and walked over and over again in the villa area of ​​Saville Town, the traces were incomplete!
Can't find the original source of that drow assassin!
The most starting point he could find was in the villa area, as if the drow assassin appeared here out of thin air, but Xia Duo didn't really believe this possibility.
Reminiscing that Zall has lived in a dark area for a long time, without seeing light all the year round, he thought of a possibility
"Maybe because of the sun!"
Chateau returned to the "art scene" again. Just now, near the location of Zall, the radiation traces are still very new, which is convenient for experimental comparison. He chose a location with the strongest radiation and summoned a light ball. After a while, It was disintegrated.
A faint trace of positive energy remained in the air, and the radiation traces left by Zall had completely disappeared.
This means that the traces left by Zall can only be discovered that night, and once the night is over, it will be "refreshed".
This also means that it is almost impossible to trace the traces of that drow assassin before dark today.
But in the same way, if traces of radiation are found elsewhere tonight, it means that the drow assassin has an accomplice, because his traces are only in the villa area, indicating that he did not leave the villa area after dark.
If there are no accomplices, how can the traces in other places come from after dark?
Or, any traces that appear tomorrow night indicate that the drow assassin has an accomplice.
However, Xia Duo was unwilling to postpone it until tomorrow night. The drow assassin did not kill during the day, which does not mean that he could not kill during the day, although this is unlikely.
If the drow assassin has an accomplice and is still killing him during the day, even if he can be dealt with in the end, the panic and loss caused will be difficult to eliminate.
Now that the existence of the drow assassin is only known to the elves and a few humans, it is the right thing to solve them as soon as possible.
...
The first thing that Xia Duo inspected was the trade zone in the east. There were many foreigners here. If this place was slaughtered by the drow assassins, the reputation of the Savile leader would probably be rotten.
Fortunately, after turning around, there was no trace of radiation, but a lot of bad news was heard. When Xia Duo left the trade zone, his face was a little bad.
After that, he went to the Southern District and the Western District in turn, and no trace of radiation was found. This made Xia Duo feel a little better, at least there is no need to worry about another drow attack.
As for the news just heard in the trade zone, since Xia Duo already knew, naturally he wouldn't let those guys succeed easily.
...
Returning to the Tower of Time, Xia Duo immediately came to the first floor and saw the drow assassin who had been imprisoned in the prison, and there were several people around outside the prison.
It was Abbock, Nia, Cecily, and Theore, who somehow came here.
Seeing Xia Duo, Niya took the initiative to greet her, "Xia Duo, you came just right! Just now we were discussing a strange item that drow carried with him. Come and take a look!"
"Oh? I want to see what can stump you!"
Chateau had just searched for the radiation traces left by drow in Savile Town. Although it didn't take much time, for a wizard who possessed the [Appraisal Technique], it would not be too difficult to know the function of an item.
Especially magic items, basically can't escape the test of [identification technique].
At first, Xia Duo thought they had found some kind of ordinary item, and it was difficult to determine its purpose, but when he saw the black ball that clearly exuded magical aura, Xia Duo realized that things might not be that simple.
So he said: "What is the result of your appraisal? It can't be completely without results, right?"
The principle of [Appraisal Technique] is similar to the sandbox simulation in the computer field on Earth. It can simulate the use status of magic items from the bottom. Although the specific details of the spell may not be known, the function can be generally judged.
Regarding Xia Duo’s doubts, Niya said annoyedly:
The identification result is that this black ball can emit weak sound waves in a specific direction. What's the use of this? But the most nervous thing about Zall is this black ball!
"You have already interrogated him? Did he say nothing?" Xia Duo asked again.
"A few simple questions, but he didn't have any words other than the filthy abuse. Uncle Ebbock told him to shut up temporarily." At this point, Niya turned her head and glanced at Zhuo, who was already unconscious in the prison. Er, there was a feeling of disgust in his eyes.
"So you were just discussing the role of this black ball?"
"Yes indeed!"
"Then what is the result of the discussion?"
"I think this should be some kind of communication device, similar to the [wind information technique], so that drow is so nervous about the black ball, but Uncle Ebbock thinks it is an attack device because of the sound waves. Even if it is weak, it has a certain aggressiveness."
As for the views of Cecily and Theore, Nia did not say, but from the expressions of the two of them when Nia spoke, it was clear that Cecily was on Nia’s side, and Theore was even more. Lean towards Ebbock's point of view.
After hearing Niya's description of Black Ball, Xia Duo couldn't help but think of a possibility, so he proposed to identify it himself, and at the same time he asked Ebbock to wake up the drow assassin.
In this way, even if he couldn't identify anything, he could use psychic spells to make Drow proactively explain the problem.
Then, Xia Duo directly selected the highest level 5 【Appraisal Technique】 he could master to cast the spell.
After all, when he was researching Feld's spellbook with Niya, the 5th ring [Appraisal] was the most used ~EbookFREE.me~ because of frequent checks to confirm whether the bridge experiment on the spellbook was in line with expectations. The low-level [identification technique] has not actually been used many times.
With the completion of the spell, a field that looked like a light group but actually resembled a "sandbox simulation space" appeared instantaneously, completely enveloping Heihe.
As the light group gradually penetrated the black ball, Xia Duo gradually realized that a "simulated black ball" appeared in the field. The spell level involved did not reach the 5th level. The highest level of the black ball involved was only 3. ring.
Later, Xia Duo easily found the excitation port of this black ball, which is the magic item switch in the general sense. At the same time, he also simulated excitation in the simulation field.
Sure enough, as Niya said, the black ball emitted a flat cone sound wave in a specific direction, and the properties of the sound wave were also reflected in the simulation field, which was in line with Chateau's previous guess.
Just as he was preparing to simulate and integrate information several times, a series of screams suddenly came out from the prison beside him. In addition to the lack of color resistance, Xia Duo heard Elvish, Dwarf, and several languages ​​with obviously different styles.
The language has changed repeatedly, and the content has not been repeated at all.
Xia Duo could only understand Elvish language, but he also had to say that this drow was really a linguistic genius. In Elvish language Xia Duo could think of, could not think of, straightforward, obscure, any negative. All of his words came out of this drow's mouth.
Of course, Xia Duo was not polite with him, turned around and came to the prison, and it was a [Shock] that was thrown away, but this judgment spell from [Projection Plane·Arcane Empire] was actually invalid for this drow assassin. !
He was just a little startled, and the subsequent yelling was even higher.
