An Linghan choked, when was she worried that Chu Xingze was tired? She's just a little embarrassed.

However, hearing Chu Xingze say this, An Linghan naturally couldn't refuse, and leaned his face on Chu Xingze's shoulder with peace of mind.

Chu Xingze noticed An Linghan's little face on his shoulder, and An Linghan's somewhat disordered breathing fell on his shoulder, and his body trembled slightly.

Chu Xingze didn't know why, An Linghan was like this, he didn't do anything, lying on his shoulder, he actually had a sense of happiness that didn't speak. And this sense of happiness is pouring out like a tide.

An Linghan also felt that the shoulders under her body were very broad, giving her a sense of security.

As the road became smoother, An Linghan felt that a wave of sleepiness was spreading around An Linghan.

So, after a while, An Linghan fell asleep.

Chu Xingze listened to the breathing of the villain on his back gradually becoming smoother, and was very happy. Because he felt that An Linghan could actually fall asleep on his back, it must have been very trusting of him!

By the time An Linghan woke up, it was already past lunch.

When Su Qin saw An Linghan's appearance, she was also frightened and distressed.

Hurriedly prepared a bunch of delicious food and waited for An Linghan to get up and eat.

An Linghan saw a table of delicious food, not to mention how happy he was, and hurriedly feasted.

waited until An Linghan was full of wine and food, and then began to deal with the entire process of the case and whether there was any breakthrough point.

An Linghan suddenly remembered the concubine, presumably the concubine was jumping in anger in the palace at this time, right? After all, the way she looked at An Linghan was that she was a dying person, and now that An Linghan had the opportunity to overturn the case, the most angry person must be the concubine.

An Linghan was very happy when he thought of the concubine being angry, and An Linghan was even happier when he thought of the concubine jumping to her feet and smashing things in anger.

Thinking of this, An Linghan laughed unconsciously.

When Chu Xingze came in, he saw An Linghan sitting by the window, the whole person was shrouded in an orange light, with a smile on the corner of his mouth, his eyes were full of cunning, and the whole person looked very lively and soft.

Although he has been facing An Linghan all day long, he has seen and heard of An Linghan's beauty, but now when he sees An Linghan, he can't help but be shocked.

When An Linghan saw Chu Xingze coming in, he retracted his train of thought, smiled at Chu Xingze and said, "Why is Xianggong here?" ”

Since Chu Xingze entered the palace to win a chance to turn the tables for An Linghan, An Linghan has become more and more gentle with Chu Xingze, and he is also pleasing to the eye.

Chu Xingze jumped up and walked to An Linghan's side and said, "Lady, you must be careful next time, I'm waiting for you at home, I'm so worried!" ”

An Linghan touched Chu Xingze's head, and then said, "I will definitely be careful next time and not let Xianggong worry." ”

Chu Xingze nodded very happily when he saw An Linghan agree.

Then, he asked, "Lady, why are you in a daze?" ”

"I'm wondering, where do I start to solve the case?" An Linghan said casually, after all, Chu Xingze's mind was only ten years old. Even if she said it, Chu Xingze would not give him any solution.

"Lady can go to the scene to see! What if there are any missing clues? Chu Xingze reminded.

An Linghan patted his head, yes! Instead of sitting here and thinking, why don't you go and see it!

She was so stupid that she even forgot about such a simple on-site investigation.

Thinking of this, An Linghan stood up excitedly and wanted to rush out of the door, wanting to go to the palace to quickly investigate the scene.

But An Linghan ran for a long time, but found that he was not moving at all, and just when he was puzzled, he heard what Chu Xingze said.

"Lady, you don't have to be in such a hurry, right? You're wearing underwear now! Chu Xingze had a few black lines on his head at this time, and said helplessly to An Linghan.

An Linghan lowered his head and looked at his snow-white underwear, and couldn't help but feel a little embarrassed.

Then he suddenly remembered something, and hurriedly called Suqin in.

Ignoring Chu Xingze's puzzled gaze, he asked Su Qin in a little panic: "Su Qin, when you changed my clothes, did you see a dagger in my sleeve?" ”

Su Qin saw An Linghan so out of shape, and also knew the importance of the dagger, and hurriedly replied: "Don't worry, princess, the dagger was put away by me, I saw that the dagger was placed very carefully by the princess, so I paid attention to it, and the dagger was not moved at all, and now it is placed on the bedside table." ”

An Linghan breathed a sigh of relief when he heard that the dagger was still there.

I was also a little glad that Suqin didn't touch the dagger too much, because if the dagger had the fingerprints of the concubine on it, then it was very likely to be covered by Suqin's fingerprints.

Fortunately, she wrapped the dagger with a handkerchief, and wrapped it in a handkerchief.

Although An Linghan had already taken protective measures, and Suqin did not touch it too much, An Linghan was still a little worried.

Because after all, the handkerchief also has the effect of erasing fingerprints, because An Linghan has been careful not to let the handkerchief touch it, so he did not let the fingerprints on the dagger be erased.

Chu Xingze was a little curious, why was An Linghan such a precious dagger?

An Linghan saw the confusion in Chu Xingze's eyes and explained: "On this dagger, there must be the fingerprints of the murderer. ”

Chu Xingze was stunned when he heard it, what is a fingerprint? Does fingerprinting have anything to do with solving crimes?

An Linghan continued to explain: "Fingerprints are the lines on everyone's fingers, and everyone's fingerprints are different, so as long as you know what fingerprints are on the dagger, you can know who killed them." ”

Chu Xingze asked curiously: "What do the fingerprints look like?" How do you make the fingerprints on the dagger appear in their original form? ”

An Linghan smiled incomprehensibly and instructed Suqin to bring iodine wine and starch.

Su Qin was also very curious, so she took things a lot faster.

An Linghan placed the dagger, starch and iodine evenly on the table.

Chu Xingze and Su Qin stood on both sides, their big eyes full of curiosity.

An Linghan felt that these materials were still a little too simple, and it would be good if there were iodine crystals. Unfortunately, the environment in ancient times was so rudimentary that iodine wine could only be used instead.

An Linghan took the lead in picking up the starch, poured some in the palm of his hand, and then sprinkled it evenly on the handle of the dagger, An Linghan was a little lucky, because although the dagger was very luxurious, its handle was flat, and it was convenient for fingerprint collection.

When the starch was evenly spread on the handle of the dagger, An Linghan poured out a small amount of iodine wine and poured it on the dagger.

The dagger turned blue in an instant, and then, An Linghan measured the dagger, observed the bulge, and then pulled out the silver hairpin in his hair and carefully scraped off the excess blue starch.

After a while, a fingerprint appeared, although it was somewhat abstract, but it was still very novel in ancient times when fingerprints had never been heard of.

An Linghan carefully put away the dagger, waiting for ten days to be used as one of the evidences.

Su Qin and Chu Xingze thought it was amazing, they never knew that iodine wine and starch would turn blue.

Moreover, there are fingerprints on people's hands!

After An Linghan put away the dagger, he casually cleaned it up.

But when I picked up the silver hairpin, I suddenly found that the silver hairpin turned black.

An Linghan picked it up and carefully observed the blackened silver hairpin, which was obviously contaminated with poison.
