Traveling through the battle with the evil emperor: the queen is too hard to pet

Chapter 302 The Murderer Is Really Him 2
"Okay, let's start."

Xia Xiaowei said eagerly.

She evenly sprinkled finely ground iron powder on the handle of the flying knife, and then used a magnet to attract the iron powder.

She wants to extract the fingerprints left by the murderer on the flying knife.

She happened to know about this before, and knew that fingerprints are a little sticky and will absorb very fine powder, so this method can be used to make it visible.

Originally, as long as there is a flying knife is enough.

But Xia Xiaowei was afraid that she would wipe off the fingerprints on it when she received the flying knife, so she also pulled out the flying knife from Chang He's chest.

Compared with the two throwing knives, it is safer.

Xia Xiaowei only knew this method in theory, but she had never tried it by herself, so she was very nervous at the moment.

The iron powder flew towards the magnet bit by bit, and the remaining ones that were still on the handle were also crowded and moving in disorder, as if they were dancing.

Xia Xiaowei's hands were slightly sweaty.

Finally, all the iron powder that could be sucked away was sucked away by the magnet, leaving a very small amount of iron powder, forming several clear fingerprints.

Among them, two of the fingerprints on the handles of the two flying knives are exactly the same, and they are very complete.

She succeeded.

If it weren't for the fact that this was a matter of human life, Xia Xiaowei really wanted to cheer and celebrate her victory.

Bei Qinghan looked at these fingerprints inexplicably, and asked: "What is this?"

Xia Xiaowei raised her finger in front of him and patiently explained to him.

"Look, each of us has fingerprints on every finger, right?"

"Correct."

"Everyone's fingerprints are different, so we can find the murderer by comparing the fingerprints."

Bei Qinghan suddenly realized.

"You mean, what's shown here are the murderer's fingerprints?"

Xia Xiaowei nodded fiercely.

"You're so smart, you can see through a little bit. So, as long as we can find the fingerprint of the suspect, we will know it by comparing it."

It's a pity that she didn't bring a camera to take pictures of these fingerprints. It won't last long if they are preserved like this.

Therefore, we must quickly find out the suspect.
