Roman voiced his speculation:

"The crime occurred in either an inaccessible alley or at the victim's home, and the time of the crime was in the middle of the night, when pedestrians were sparse and patrols were intensive."

The director nodded: "That's right, but we checked and interrogated the pedestrians that night, but we didn't find any suspicious targets." ”

Roman looked up at the sky, looked at the dense buildings, and continued: "If the criminal escapes from the rooftop, won't you be able to find it?" ”

The director thought for a moment and affirmed: "If there is no moon, we really can't find it with torches alone, but the roof is at least ten meters high, right?" How can ordinary people jump on it? ”

Roman shook his head: "Mortals can't, but transcendents can, just a knight can do it." ”

The Director was incredulous: "No, a proud knight would be willing to mingle with mortals?" And when registering for naturalization, it will be investigated, and if it is a knight, it will be easily discovered. ”

At this time, Roman asked, "What if he became a knight after naturalization?" Can you find out? ”

The director took out a piece of jade and said, "This thing, once a knight approaches, it will glow." ”

The magic power of the Roman spirit was swept away, and he immediately knew the principle, and the Academy Alliance of this thing was also used, but the wizard had already studied a way to crack it.

Thinking about the wizard behind the murderer, it's easy to hide the detection.

So he concluded: "The murderer is a knight with the support of a wizard behind him." ”

Then he pointed to the center of the criminal's area on the map and said, "Now give me a horse, I need to go to this place." ”

The commissioner immediately complied, and Roman rode out with a few police detectives who were familiar with the area.

With the endorsement of the Sheriff's Office, Roman arrived at his destination unimpeded.

He was in a lively square, surrounded by pedestrians, and the Director asked:

"Romance Wizard, there are more than 200 squares in this area you painted, plus tens of thousands of pedestrians, we don't have enough people, do you want to call reinforcements?"

Roman said lightly: "No, I'm just alone." ”

After that, he ordered in his heart: "Chip, spread the essence magic, scan all genes, compare with the missing, and mark suspicious locations!" ”

"Ding! The task is established, the scan begins... Expect it to take half an hour..."

This is estimated to be the heaviest task of the chip, and there are so many genes in a large area that the chip needs to be compared one by one and carefully screened.

The prophecy witchcraft is interfered with, and Roman can only use this stupid method, relying on the super computing power of the chip to pull the net to investigate.

However, this method can also be used by Roman, although the first-level wizard brain has been developed and the computing power has been improved a lot, but the comparison and analysis of the genes of each cell is still not enough.

Half an hour passed quickly, and according to the instructions of the chip results, Roman indicated dozens of points on the map, and then wrote down the numbers of the residual genes, eliminating them one by one.

When a murderer kidnaps, he will definitely find a place to hide the victim, and there are not many such places in the inner city where the investigation is heavy, so it is likely to be stored in a centralized manner.

As long as you find out where the victim's genes are dense, you can find the murderer.

"These are residences, and there is only one residual gene, exclude..."

"This is the bar, two of the victims are friends, there are no other victims left, exclude..."

After a call was cleared, there were only two suspicious locations left on the map, which collected the DNA information of the five victims.

"These two places, one is a residential area and the other is a tavern, can you find the owner?"

The director nodded and said, "Yes, I'll order it right away!" ”

Soon, the identity of the head of the household was revealed, and as Roman expected, they were all the same person.

He said coldly: "You can arrest people, but the target is likely to be an extraordinary, it is best to report to the law enforcement team first, you mortals can't beat it." ”

The Director looked solemn: "Thank you, Romance Wizard, for your contribution to the people!" ”

Roman sneered in his heart: "But because the rations were robbed, the Extreme Devourer was unwilling!" If he had to contact the black market, he wouldn't bother to bother with it! ”

But he said kindly: "Yes, remember to confirm my title with the law enforcement team!" ”

Since he could not use witchcraft, the arrest had nothing to do with Roman, and the next day, a clerk came to him and told him that he had been promoted.

At this moment, Roman was promoted to the third-class knighthood, and among the tens of thousands of wizards in the free city-state, there were very few third-class titles, and he was promoted to the knighthood in less than half a year after settling down, let alone not.

The third-class title increases the range of activities, allowing you to travel across city-states, as well as travel to the black market to buy wizard resources.

Although you can only go once a year, it is already a great breakthrough, and many wizards make a lot of money by doing daigou.

But Roman is not short of magic stones, not to mention that there are still a large number of rune stones that have not been used up, and the magic stone reward for slaughtering the island has not yet been moved.

Therefore, he didn't buy on behalf of him, and immediately went to the black market.

After showing the knighthood badge and pass, the enforcement team waved Roman through.

He found that an area was thoughtfully circled with a red line on the ground, representing the entrance to the black market, Roman walked in, chanted a spell softly, and the surrounding scene was illusory, and he appeared in the black market.

The black market is not large, and compared to what Roman used to go to, it is at most medium-sized, which means that there are not too many goods.

After some purchases, Roman bought a small bag of essentia crystals, which he felt were too few, and these essentia crystals increased the atomization by up to 5 percentage points.

However, the next time he came over, he would have to wait until a year later, which would greatly slow down his cultivation speed, and Roman would not be able to wait for a year.

Therefore, he set up a stall on the side of the road, listed for the purchase of essentia crystals, and successively acquired some, which can increase the atomization degree by 2 points.

Soon, at the end of the two hours, Roman was expelled from the black market, looking at the bag of essentia crystals in his hand, and sighed helplessly.

After returning home.

"Ding! The atomization degree of essence magic power has been increased, and the current atomization degree is 37%..."

This is the harvest of this trip, if you want to improve again, you have to wait until a year later, in the eyes of Roman, who is eager to become stronger, it is still too slow.

He couldn't wait a year, and he planned to go to another black market in the short term, but in this case, he would have to raise the knighthood again.

"How do I do that?" Roman fell into deep thought, after the third-class title, if he wants to be promoted, it is no longer effective to hand in more products, and he must make meritorious contributions to the city-state.

Just like earlier, Roman assisted the law enforcement team in handling cases and successfully rose to the third-class knighthood, and if he wants to be promoted again, he will have to handle more cases.

But this kind of opportunity doesn't happen often, after all, the law enforcement team and the sheriff's department are not waste, even if you meet it, there are a bunch of wizards waiting to be promoted, how can it be your turn Roman?

Roman pondered for a while, and there was no good countermeasure for a while, and just as he was about to give up, a knock on the door interrupted his train of thought.

"Roman! Roman! Open the door, there's another case! ”
