psychochemist

Chapter 58 The Bleeding Heart
Yu Fan moved towards the door step by step. Since the screams outside the office just now, there has been silence outside again, deathly silence.

Yu Fan moved to the door and stretched out his hand to pull the door. Although he was very nervous, his hands didn't shake at all. This may be a chemist's professionalism. Steady hands are more accurate when doing experiments. After all, a little If you're not careful, the dose percentages can make a world of difference.But Yu Fan's hands were full of sweat.

Yu Fan fixed his eyes on the doorknob, took a deep breath, touched the doorknob with his right hand, and pulled the handle in very gently.

Squeak~~~~squeak~~~
Oops!Even though Yu Fan was already very light, there was still a sound when he pulled the door. It must be that the hinges of the door were rusted, which caused the lubrication to drop, making the sound.At this time, there was the sound of slow footsteps outside the door. The sound of footsteps was far away, but it was very obvious in this extremely quiet environment. Da, da, da, it was impossible to hear whether the footsteps were getting closer or further away.

Yu Fan quickly stopped, he held his right hand with his left hand, panting heavily, he didn't dare to look at the doorknob.

At this time, Yu Fan's face was covered with sweat, and the sweat dripped down his cheeks to the ground, and his glasses were foggy from the heat of sweating.Yu Fan wiped the lens with his finger and took a deep breath.

At this moment, the footsteps stopped, and there was only the sound of Yu Fan's heavy breathing and Yu Fan's heartbeat in the air.

Yu Fan adjusted his state and continued to open the door. This time when Yu Fan opened the door, he gave the door an upward force, and the door stopped making any noise.

The door opened a sufficient gap, and Yu Fan squeezed through the gap.

Yu Fan was stunned by the scene outside the office!this is?
This is a very large laboratory, about 200 square meters, without windows, it is a closed space, there are many lights on the roof, but the light is very dim, there are three rows of experimental benches in the whole large laboratory, on which there are All kinds of bottles and jars, as well as large glass jars filled with some specimens and so on.

The fishy smell in the air became stronger, and along with the fishy smell, there was also a pungent smell.

Yu Fan scanned the surroundings carefully. There was no one there. Follow the road to the end of the laboratory. There is another door. There is a sign above the door that glows green. If there is no accident, that is the safe exit.

Yu Fan moved forward slowly, observing the surrounding environment while moving.

The light was too dark to see clearly just now, and when he approached, Yu Fan was shocked. The large glass jars on the test bench were filled with liquid, and the specimens in the liquid turned out to be...

human organs! ! !

This is not a sample organ from an ordinary laboratory, the organs inside seem to have just been put in!Because there are still bright red blood streaks separating out from the organs, floating in the liquid, this scene is like throwing a freshly killed fish into the water, its blood slowly oozes out and spreads with the corpse, it is very scary! ! ! !

Yu Fan took a closer look at the organs inside, and couldn't help but gasp, it turned out to be hearts! ! !One in each jar, traces of blood are coming out.

These are, bleeding hearts!

What the hell is going on here?Yu Fan tried his best to recall, but he just couldn't remember, the harder he tried to recall, the more severe his brain ached.

"Psychochemist, we meet again." A gloomy voice came from behind Yu Fan.

Yu Fan suddenly turned his head, surprised, it turned out to be Zhang Shengqian who was captured in Beiqiaogou at that time!Zhang Shengqian was dressed in black, with a screwdriver in one hand and a fire extinguisher in the other.Zhang Shengqian's face was only half, and the other half was bloody and bloody from the heavy object.Zhang Shengqian stood behind Yu Fan, about ten meters away. Although he only had half of his face, he still showed a sinister smile.

Such a terrifying scene made Yu Fan feel very familiar.Are you dreaming?But why is this dream so real?

Yu Fan said to Zhang Shengqian calmly, "Although I don't know why you keep showing up, what exactly do you want to do?"

Zhang Shengqian pointed at his own smashed face, then shook the fire extinguisher in his hand, and pointed at Yu Fan again, a gloomy voice sounded: "I became like this, it's all because of you!!"

Yu Fan didn't know where the courage came from, and said, "So?"

Zhang Shengqian said fiercely: "See these bleeding hearts in the jar? I will kill you, dig out your heart, put it in these jars, and be one of my trophies."

"Hahahaha." Yu Fan suddenly started laughing.

Zhang Shengqian said angrily: "Death is imminent, what are you laughing at?"

Yu Fan: "I think you're trying to boost your strength and play tricks. These so-called 'bleeding hearts' are actually fake!"

Zhang Shengqian smiled coldly: "Oh? What did our psychochemist discover?"

Yu Fan: "If it is a real heart or human organs, in order to preserve them, they are soaked in formalin liquid, that is, 35-40% formaldehyde solution, which has a strong pungent formaldehyde smell."

Yu Fan opened his hands, as if he was holding the air, and said: "But you smell the air, it's full of a strong sour smell. Could it be that acid is used to soak the heart? Doesn't that aggravate corrosion? This smell doesn't fit the herbarium the taste of."

Zhang Shengqian casually pulled a stool from under the experiment table and sat down, nodding with a sneer: "It's interesting."

Yu Fan continued: "So I boldly infer that the liquid in your jar is not formalin, and the heart inside is not a real heart. In my opinion, your liquid is potassium thiocyanate solution with a little concentrated hydrochloric acid, Then add a little hydrogen peroxide, and finally prepare a mixed solution. And this heart is actually a model heart made of iron, which is not easy to find in dim light.”

Zhang Shengqian showed a very abnormal demeanor, both insidious and approving: "Continue."

Yu Fan: "Iron and hydrochloric acid form ferrous ions, which are oxidized by hydrogen peroxide to form ferric ions. Ferric ions and potassium thiocyanate form a complex called ferric thiocyanate. This complex is blood filaments. state, so we can see the 'heart' is bleeding continuously, you use this method to imitate the real heart bleeding and create a terrifying atmosphere. However, this is all your trick in the end, the bleeding heart." Yu Fan After all, he flicked a screw on the experimental bench into the glass jar. Like those 'hearts', the screw began to 'bleed', leaving a bright red silk screen as the screw fell.Sure enough, it is iron.

Zhang Shengqian stood up slowly while applauding, and said: "Your reasoning is completely correct, and your last words are also wonderful, but soon, I will have my first heart that truly bleeds!"

Before he finished speaking, Zhang Shengqian picked up the screwdriver and rushed towards Yu Fan!
　A person can be poor, but the heart cannot be poor, the energy in the heart is inexhaustible; the body can be crippled, but the heart cannot be crippled, and the health of the heart is inexhaustible. ——Potassium Rhodicyanide
