Su Wen closed his eyes and spread his consciousness, and with a slight fluctuation of magic power, the map range in Su Wen's mind expanded at an extremely fast speed, until it enveloped the entire Snow Castle City. The inhabitants of Snow Castle City were all mapped on Su Wen's map in the form of white dots.

But unfortunately, Su Wen did not find any trace of the Black Rope Society assassin.

Similarly, even Ellie felt no signs of the presence of other Black Rope Assassins.

Then the conclusion is clear, only the assassin with the concealment ability can hide from Su Wen and Ellie at the same time, so that he can poison Marina's cup without knowing it. And such an assassin, so to speak, does not exist.

Therefore, the scope of the murderer is locked in these people.

"Unfortunately, there are no such assassins. Su Wen said to Balot.

Barot took a deep breath and said, "In other words, is the murderer locked in among those people......

"Not really. Su Wen shook his head, and said to Ellie, "Did you miss a few people?" ”

"Missed?

Missed?Barrot was also surprised, could it be that Su Wen had just listened to her introduction and at the same time also diverted his energy to pay attention to Ellie's side? Is this something that a young man who looks a few years older than her would do?

Su Wen's approach reminded Barot of some of his teachers, those old magicians who had been baptized over the years and accumulated countless life experiences.

"Kyle and the kids next to him, you haven't confirmed it yet. ”

"Huh??" Ellie and Barot were surprised at the same time.

A group of ten-year-old kids, do you want to be confirmed?

Although Ellie was confused, she walked over and sniffed the scent of several people. When Ellie returned, her expression became strange.

“...... There's really a little bit of residual smell on them......"

"What!?"

Barot felt that her brain was not enough, why did those children also have toxin residues on their bodies?

"Do you remember the range of movement of those children?"

"I remember. Ballot nodded, and began to recall: "After eating some food, the children began to play together, running around the hall, playing hide and seek, and the specific range of activities should be in this banquet hall, as far as the maids' preparation room......"

The preparation room, where food and drinks are prepared, is out of view of Barot and is blocked by a curtain, so it can be said that it is out of everyone's sight.

"Have they been to the preparation rooms on either side?"

"Yes, I've been on both sides. Baro nodded in confirmation, and then explained the layout of the entire banquet hall to Su Wen.

The main hall is a rectangular space, three-quarters of the south is the banquet center area, the middle of the whole center area is an open dance floor space, surrounded by orderly rows of tables and chairs, the position of the balot, in the corner with a wide view of the south, and the north quarter is a space for a podium and tables for food, and there is a door to the back hall.

On the east and west sides of the banquet hall there is a side corridor, and at the end of the side corridor is the preparation room covered by a curtain, and the toilets are also entered from here.

In other words, there are two preparation rooms.

The wine that the young men had drunk just now came from this room on the east side.

"Did all those people just now go in and out of the preparation room?"

Barot recalled carefully and said, "Those children, I should have been on both sides, Grandpa Ivan went to the east room, because his seat was on the east side of the dance floor...... As for my mother and the three ladies, their table was in the center, and it made me think......"

"My mother went to the preparation rooms on both sides because of the need to arrange manpower. Lady Lisa and Lady Aisha also passed through the preparation room because they had to go to the bathroom halfway, but at that time the two seemed to be angry, Lady Lisa went to the west, and Lady Aisha went to the east. ”

As for Mrs. Windy, it seems that Kyle spilled the soup on his coat out of playfulness, and then Mrs. Windini took Kyle to the prep room to change his clothes, but ...... It's the one on the west side. ”

"My father and Grandpa David, after Brother Shiwengo came in not long ago, went out through the west side porch...... And then he came back......"

Warrente went out because of the four Black Rope Assassins.

"So, what about the order in and out of the preparation room?

Barrot shook her head and said, "I can't remember, but Kyle's little kids have been going in and out, and everyone else, except for my mother, has only been in once......"

"But...... My mother could never have been a murderer!"

"Take it easy...... didn't say that the one who went in more often must be the murderer. ”

"After we've eliminated some of the people, the only suspects are Ivan, Aisha, and Vivien?" concluded Ellie.

"No, and that group of kids. ”

Su Wen touched his chin and thought about it.

Taking advantage of the quiet, Barot unconsciously set his eyes on the suspects.

Her mother, Vivian, was grabbing her brother Lawson, talking and laughing in front of a beautiful young lady and her parents, looking at Rosen's embarrassed expression, probably trying to match the marriage between the two.

After an awkward encounter with Lady Lisa, Lady Aisha had a heated conversation again, and kept chuckling with her mouth covered.

Grandpa Ivan seemed to be a little tired, hung his head, and was napping together in a regular manner with the rhythm of his breathing. His personal attendants were keeping an eye on Ivan's situation.

These three people, will they be murderers?

If not, then the killers are the kids who are tired of playing and sitting on the edge of the dance floor drinking drinks?

Barot couldn't believe it.

When I was a student at the Imperial Academy, I had heard about the terrible struggle for power among other aristocratic families, and I understood the intrigue involved. But such a thing happened in Snow Castle, which has always been amiable, but she never imagined.

"Okay, then, let's go to the scene of the crime. ”

Su Wen sorted out the current clues, got up and walked to the preparation room on the east side.

It is not enough to identify the killer based on current clues alone.

Su Wen still needs more clues.

The identity of the suspect and the motive for the crime, Su Wen has a general understanding, and next, he still needs to find the modus operandi!

In this way, field trips are necessary.

It's a little late, but I hope the maids haven't destroyed the crime scene yet!

......

Marlena slowly raised her eyelids, and the consciousness in the chaos returned to her body.

"Miss?" David called tentatively, and the stone in his heart finally had the meaning of falling.

"......" Marlena opened her mouth and fell back into a deep sleep.

I'm finally out of danger...... David breathed a sigh of relief and immediately reported the news to Warrente in the form of a sound transmission.
