Chapter 321 Poison that is hard to swallow

This is often the case with people, turning their strongest side to outsiders, and leaving their softest side to their family members.When you feel your lover is soft, that may be a sign of his strength.

Xiao Li continued to describe the scene of that year...

Liu Hailing's face turned pale, and she asked Ma Jiapeng in a panic: "Ma... Team Leader Ma, is this true? I... caused you to lose your position..."

Ma Jiapeng closed his eyes, smiled nonchalantly, and said, "Well, Hailing, don't worry about these details. Each of us will eventually become dust in history, and how many future generations will care about those false names?"

Liu Hailing bowed deeply to Ma Jiapeng, and said very sincerely: "Team Leader Ma, I'm sorry, I got you into trouble."

Ma Jiapeng said kindly: "Hai Ling, don't worry about that, tell me the truth, did you do this? I won't report you, but I want to hear the truth from you. Hmm."

Liu Hailing raised her head and said righteously: "I really didn't do it. But Team Leader Ma, I swear to you, one day, I will definitely find out the person who really hurt you!!! I will give you justice .”

Xiao Li sneered at the side: "Huh, it's still acting..."

Ma Jiapeng patted Xiao Li on the shoulder, smiled and said to the two: "Okay, let this matter become the dust of history. With Hailing's promise, this is enough..."

At this point, the matter was sealed up, and Xiao Li also followed Ma Jiapeng's instructions and did not announce the matter to the outside world.

Time went back to the present.Xiao Li vividly described the scene of that year.

After speaking, Xiao Li pointed to the cabinet in Liu Hailing's lounge and said, "everything I said is true, and I also know that the box of sinful laxatives is still in Liu Hailing's cabinet! I don't know if he deliberately didn't have 300 taels of silver here, but Liu Hailing never took away the laxatives and destroyed them."

Everyone looked at Liu Hailing's cabinet in unison.

Ma Jiapeng: "Xiao Li, that's enough, don't say any more, there is no real evidence, these are just speculations..."

"Guess? Brother Ma, you are too kind, so you are always bullied!" Xiao Li complained, and then walked to Liu Hailing's cabinet by himself, "Now let everyone see the real evidence!"

Xiao Li turned the switch and opened Liu Hailing's cabinet, but Liu Hailing's cabinet was not locked.Xiao Li rummaged through it, and sure enough, he took out a green box from it.

Xiao Li threw the box on the table for everyone to see.

I saw "Guoguo Tablets" written on the box, and the first item in the instructions on the box clearly stated: "Indications, for the treatment of habitual intractable constipation."

Xiao Li added: "Pay attention to the production date, it is the period before the accident a few years ago!"

This... This is indeed a laxative!People around are talking about it.

"It seems that this Liu Hailing did it.", "It's a stone hammer, and it really didn't wrong him.", "It's too dark for this kid."

Yu Fan silently picked up the small box, looked at it over and over, and pondered for a while.

Lin Niulong approached Yu Fan and said in a low voice, "Yu Fan, what do you think about this matter? Should you call the police directly?"

Yu Fan suddenly laughed loudly, everyone around looked at Yu Fan with puzzled and strange expressions, what's wrong with this man?
Yu Fan patted Lin Nilong on the shoulder, and said to everyone: "This further proves that the murderer is not Liu Hailing!"

Xiao Li said angrily and startled: "Officer Yu, from the moment you came in I felt that you were partial to Liu Hailing, and now the evidence is solid, are you still blind?"

Yu Fan was happy, and said lightly, "I'm not blind, and neither are you. So whether Liu Hailing is the murderer, we can see clearly with our eyes."

Ma Jiapeng asked curiously: "Officer Yu, it's been so long, what do you think?"

Yu Fan: "Xiao Li, do you have disposable paper cups in the lounge? Please get one for me and fill it up with water."

Xiao Li: "Yes." Although he didn't know what Yu Fan wanted to do, he still went to get a water cup from the cabinet under the water dispenser, filled it up and brought it over.

Yu Fan opened the box of the fruit guide, took two pieces from it, took a thermos cup from the table, and crushed the fruit guide with the bottom of the cup.

While grinding the Guodao tablet, Yu Fan said: "The medicinal principle of the Guodao tablet is that the contact laxative stimulates the nerve plexus in the intestinal wall, directly acts on the smooth muscle of the intestine, increases intestinal peristalsis, and at the same time promotes fluid circulation. Accelerate the laxative effect by accumulating with ions in the intestine."

After finishing speaking, Yu Fan poured the finely ground fruit guide powder into the paper cup.Then use a straw on the table to stir vigorously in the cup for a while.

Yu Fan stirred very vigorously. After about 40 seconds, Yu Fan stopped and quietly placed the cup on the table.The water in the paper cup also slowly calmed down.

The water completely returned to calm. At this time, everyone was surprised to find a problem!This glass of water is completely "undrinkable"!

Because everyone present could clearly see that the water in the water glass was very turbid at this time, and a large number of solid fine particles were suspended in the water. The quality of the water is such that no one with eyes would drink it. At a glance, it can be clearly seen that this is obviously not pure water!

Everyone discussed again, "When I drank the water, it was as dirty as I had never seen before.", "Yes, every time I drink water, I will carefully check whether the water is clean, after all, it is made by the factory itself. Pure water.", "Such turbid water must have a bad taste after drinking, and it is easy to find."

Lin Nilong asked Yu Fan puzzled: "Yu Fan, what is the principle?"

Yu Fan explained to everyone: "Guodao tablets actually have another name, which is phenolphthalein tablets. Phenolphthalein is in the form of crystal powder, almost insoluble in water, with a density of 1.323g/cm318.32 and a molecular weight of [-]. It is colorless in neutral solution and purple in alkaline solution. It is often used to detect acid-base. Phenolphthalein is an irritant and is used for chronic constipation. It can directly stimulate the intestinal mucosa or activate the nerve endings of intestinal smooth muscle and increase intestinal propulsion."

Lin Nilong: "Phenolphthalein! I only know that it is a common acid-base indicator in middle school, but I didn't expect it to be used as a laxative?"

Yu Fan: "That's right. Phenolphthalein is almost insoluble in water, so even if it is ground very finely and poured into water, these particles will be suspended in the liquid, and the whole liquid will look extremely cloudy. So the laxatives you take must not It will be the phenolphthalein tablets in Liu Hailing's cabinet."

Xiao Li: "However, this only shows that Liu Hailing's release is not a fruit-directed film, and it does not prove that Liu Hailing did not do it."

Yu Fan: "That's true, but let's think about it the other way around. If Liu Hailing did it, how dare he keep this box of laxatives in the cabinet like a melon field?"

Yu Fan paused for a moment, and then said: "Besides, there is a more serious fact before our eyes!"

The atmosphere in the air suddenly became tense...
