    The autopsy was a necessary procedure in this case, and it did not bring many clues to the case.  When a group of us hurried back to the department, Lao Xian was already waiting in the courtyard early.  The big lamp on the courtyard wall illuminated the entire courtyard like daylight. Lao Xian found a long table from somewhere, with a lot of scattered items piled haphazardly on the table.

    "Old Xian, what are you doing?" Fat Lei stroked his big belly and walked over unsteadily.

    Without saying a word, Lao Xian pulled out a piece of white paper from the table and slapped it with his palm. A bloody handprint appeared on the paper.

    This scene made us all dumbfounded.

    ¡°I x!¡± Fat Lei instinctively took a step back.

    Soon after he said it, Lao Xian suddenly flicked his finger, and his index finger actually lit up with flames.

    ¡°I x, what the hell?¡± I swore.

    Lao Xian looked relaxed. He made a fist with his left hand and extinguished the flames on his fingers. He quickly pulled out a small pile of yellow paper from the table and lit it with a lighter. Then he threw the burning yellow paper into the sky with the light of fire.  The yellow paper fell slowly, and just when the yellow paper was about to hit the ground, the flame was extinguished just in time, and then five large hollow characters appeared in front of us: Corpse Investigation Division.

    "Wow, Teacher Guoxian is great." Ye Qian clapped her hands in praise.

    "Guoxian, where did you get these things?" As the saying goes, laymen watch the excitement, while insiders watch the door. Judging from Brother Ming's reaction, Lao Xian is definitely not doing some "artistic performance".

    "These are all extracted from the deceased's home." Lao Xian took out a tissue from his pocket and wiped his hands.

    "Ye Qian, ask Team Xu to find the deceased's daughter. She has something to hide from us." Ming Ge said and walked straight to the office.

    "Ohohoh." Ye Qian obviously didn't understand what Brother Ming meant yet, so she nodded casually.

    "Old Xian, what were you doing just now?" In our department, the most curious person is Ye Qian, and the second most curious person is undoubtedly Pang Lei.

    "These are all charlatanism." Lao Xian led us to the table, took a piece of white paper from the table, repeated the action he had just taken, and then pointed at the bloody fingerprints that had just been taken and said, "This trick  In charlatanism, it is called 'blank paper and blood seal'."

    "It was originally a piece of snow-white paper. When the 'Master Jianghu' pats it hard, a bloody fingerprint will appear on the paper. At this time, the 'Master Jianghu' will often tell you that the demons and ghosts in your home have been surrendered by him. As long as you  After giving the money, the 'Master Jianghu' will put the paper with the bloody fingerprints on it into the basin, and the bloody fingerprints will slowly disappear. At this time, the 'Master Jianghu' will say that the ghosts have been driven away."

    "What's the principle?" Ye Qian asked.

    "This is mainly due to the chemical reagent phenolphthalein. Phenolphthalein will turn red when it encounters alkali, and will naturally fade when it encounters acid. In fact, 'Master Jianghu' took advantage of this simple chemical reaction. First, spray phenolphthalein onto a piece of white paper.  Let it dry until it looks like a nice piece of white paper. Then when you do this, dip your hands in some alkaline water. When you pat it upward, red fingerprints will appear. Then add some dilute hydrochloric acid or white vinegar to the water.  , the bloody fingerprints will naturally disappear."

    "So magical?"

    Hearing Ye Qian¡¯s exclamation, as a science guy, three black lines instantly appeared on my forehead.

    "Brother Xian, your finger spontaneously ignited in the second move just now. Is it because of the white phosphorus?" I fully understood the meaning and started to answer.

    "right."

    "White phosphorus?" Ye Qian looked at me with stars in her eyes.

    I shook my head helplessly and asked: "How can fingers catch fire under normal circumstances? It's actually very simple" At this point, I glanced at the three powders on the table and asked: "Brother Xian, these three  Are the powders camphor, white phosphorus and sulfur?¡±

    "right."

    "Then this is easy to explain. Camphor is volatile, and sulfur and phosphorus are easy to burn. As long as you rub it with your fingers a little and the heat is right, it will burn quickly. Why couldn't Brother Xian burn himself just now? Because he had applied it on his hands beforehand.  A layer of flour. Brother Xian, am I right?"

    "That's absolutely correct." Lao Xian gave me a thumbs up.

    I smiled and continued: "Then the last trick is even easier. Words can appear after the yellow paper is burned. In fact, these words are written with a chemical, the most commonly used is potassium nitrate. Potassium nitrate is manufactured  A component of gunpowder, in chemical research, it is a strong oxidant and a combustion accelerant, which is relatively easy to dissolve in water. Brother Xian used potassium nitrate solution to write words on paper, and then dried it.After drying, the potassium nitrate particles will adhere to the paper. Once the paper encounters fire, the part where the potassium nitrate is attached will be particularly easy to burn, so the words will appear.  "

    ????????????????????????????????????????????????????????????????????????????????????????????!  Lao Xian replaced everything with applause.

    "You know a lot!" Ye Qian held her waist with both hands and looked me up and down with squinted eyes.  She, a liberal arts student, was tortured a thousand times by me tonight, how could she feel comfortable?

    "Not only these, I have also heard of many scams, such as 'fried ghosts'. A pot of steaming oil is boiling. The 'master' can put his hand into the boiling oil pot to retrieve things. The principle is actually  Chemical substances such as calcium carbonate and borax are added to the oil pan. When these substances react chemically, they will produce gas. The bubbles will bubble up to the oil surface, which looks like the oil is boiling. In fact, the oil temperature at this time is very low.  .¡±

    "There is another 'burning cotton thread'. A copper coin is suspended from an ordinary cotton thread, and the 'master' ignites the cotton thread. But the strange thing is that the cotton thread is obviously already burning, but it does not stop burning. At this time, the 'master'  It is usually claimed that this is because the ghost's magic is too clever, so the cotton thread keeps burning no matter how hard it is. If you want to crack it, you have to pay. In fact, the cotton thread used by the 'Master' has been soaked in salt brine, which contains potassium chloride.  , magnesium chloride and other substances. If you tie the copper coin with such a thread, it will appear to be on fire. In fact, only the surface of the thread is burned. The inside of the thread is protected by potassium chloride and magnesium chloride and does not come into contact with the air.  , so it didn¡¯t burn.¡±

    "There is also a 'clear water explosion', which is actually throwing a piece of metallic sodium into the water, etc. These are just some of the most basic chemical principles."

    When it came to the last sentence, I emphasized the word "basic". Ye Qian rolled her eyes and looked at me while listening.  Lao Xian and Pang Lei smiled and said nothing, watching the two of us playing tricks.

    But getting back to the subject, judging from the physical evidence we collected, the deceased Hou Qin is not as simple as we thought. She is most likely the "master" I call her.  As the daughter of the deceased, it was impossible for Hu Yuan to not know what her mother was doing outside, but she said nothing about it.  So after watching Lao Xian's "performance", Brother Ming immediately ordered the deceased's daughter to be called over to inquire about it.  Only after the causes and consequences of the matter are thoroughly understood can the following case research be carried out further.  (Remember the website address: www.hlnovel.com
