According to the notice he had just received and the authentication of the card given by the man with glasses, Qiao Sen was sure that the group of people who came to him in military armored vehicles were the people who the director had said before to come for technical assistance.

Qiao Sen commanded a few of his men to go up and act as coolies, and by the way, he observed the instrument that the technicians had brought with him.

From the outside, the shape of the instrument is like a silver-white disc like a pot lid installed on a metal square cabinet, and a ten-centimeter-long metal probe with a telescopic thread on the surface is erected in the center of the disk.

After that, the man with glasses in charge of the team stepped forward and grabbed the metal plate above the instrument and pulled it open like a flip cover, revealing a console full of buttons and displays.

Beep ......

After the glasses man performed a series of operations that Qiao Sen couldn't understand on the operating table, he saw that the indicators and display screens on it were all lit up, and the text and symbol data were constantly refreshed, and at the same time, the radar-like device in front of the instrument began to be covered with a layer of light that could be clearly seen in the dark night, and an invisible and almost inaudible spiritual power fluctuation spread out.

Swept over the ruins of the church by this faint spiritual wave, you can clearly see that a circle of light particles like fireflies flashed out in a short period of time, and with the spread of the spiritual wave, it swept over the ruins of the church like a wave of water.

Several other technicians walked into the ruins with a few small funnel-style machines, and after placing these small machines on the ground and activating them, they saw that the funnels unfolded a magic circle with a diameter of more than two meters, and then there were constantly free spirit children in the air who were pulled by the magic circle and gathered over, and finally were sucked into the machine.

After this scene lasted for four or five minutes, the man with glasses turned off the large radar-like instrument, and the other technicians also collected the small funnel machine that had been placed on the ground of the ruins to absorb many of the free spirits in the atmosphere of the scene.

"It's okay, call it a day. ”

Seeing that they were starting to move the instruments back into the carriage, Qiao Sen stepped forward and asked the man with glasses curiously, "How is it, have you gained anything?"

"Oh, that's fine. You know, based on the information confirmed in advance, it was speculated that tonight's attacker may have used a spirit guide weapon to commit the crime, right? The research and development of the spirit guide weapon is what we technicians are good at. The other party lifted the glasses on the bridge of his nose and said: "According to the latest argument from a research institute in the empire, in fact, in terms of the attribute composition of the spirit son, the fluctuation of spiritual energy, etc., it is the same as the spiritual power of each elf envoy has subtle characteristic differences, even if the spirit guide weapon is made in batches from the factory, because of the difference in production technology and environment, there will be differences between each other. ”

"I see. Qiao Sen listened and nodded silently.

"Therefore, since we deduced that the other party was using a spirit guide weapon, we collected the data of the free spirit children that remained at the scene. The man with glasses pointed to the machines they had just made, and continued: "Of course, because of the needs of large-scale mass production of military weapons, spiritual guide weapons are often produced according to the established process, even if different producers make a move, the differences between the remaining spirit children after their use are very subtle compared to the differences in spiritual power between human elves, even if there is a special machine to analyze, it will take a lot of effort to obtain accurate results." ”

Jossen asked knowingly, "So, still can't get any clues about the attacker?"

"Yes, we can't provide you with an answer right away, and the current technology is only in the preliminary stage, and it will take as little as three to five days to as long as ten and a half months to analyze the definitive results. The man with glasses smiled bitterly, and then his face suddenly hesitated.

"Well, what's wrong?" Jossen noticed his strangeness.

"Sir, what I'm going to say so far is just a personal speculation, and it can't be used as definitive information, do you want to listen to it?"

"Oh?" Qiao Sen thought curiously and nodded directly.

Although it's just a guess, since the other party said it, there should still be some basis for the explanation, and it will take several days for more accurate results to come out anyway, so it's okay to listen to it before then.

Until more accurate results are analyzed, follow this guess that may be correct for the time being, and maybe you can gain something in advance.

"As you know, the current military spirit guide weapons of the empire were developed by technicians like us...... "The man in glasses leaned over and said in a low voice: "Therefore, we are naturally very familiar with the data of the spirit guide weapons produced by the empire itself, so ......"

At this point, the man with glasses shook his head and stopped talking.

Qiao Sen, who has been in charge of security and defense work for a long time, and usually takes over all kinds of difficult cases of citizens, naturally his brain will not be inflexible, and after he recalled the meaning of the glasses man's words, his face suddenly changed slightly.

"Wait, are you saying that the spirit guide weapon used by the other party is actually from ......?!"

"Ahem...... sir, again, this is just a personal speculation based on experience, and it has no accuracy. The man with glasses coughed lightly and said with a somewhat cautious expression.

At the same time, he vaguely glanced at the high-end residential areas where those dignitaries and nobles lived in the imperial capital.

"I see, this piece of information is still quite useful. Qiao Sen also noticed his small movements, and after being silent for a while, he nodded, smiled and took out a handful of gold coins from his pocket, and quietly stuffed them into the pocket of the white coat of the man with glasses.

Jossen's action was obviously very useful to the man with glasses, and it was not in vain that he took some risks to prompt.

"Well, we're going to leave you at that, and we'll let you know as soon as we have accurate results. ”

"Thank you for your hard work. ”

Jossen waved his hand politely, watching the technicians' cars disappear into the night, and after a long time, he grabbed his hair irritably, and took out a pack of cigarettes from his pocket to light for himself, so as to soothe his mood.

'Really, is there a stain on some of the upper echelons of the empire behind the scenes?' Although I haven't heard of this kind of thing before, counting the number of destroyed churches mentioned in the intelligence, the spiritual guide weapons that can meet the needs of such a large-scale operation are definitely not small this time......

Qiao Sen felt that if he really followed this clue to investigate, he would be very bad!
