A treasure-appraisal maniac

"You want to use the lab?"

"Pooh!"

"Why do you have the nerve to speak!"

"My bay horse was ridden away, causing me to walk for more than half an hour. My legs still hurt!"

"If you want to use the laboratory, wait until this girl calms down!"

"You don't need to glare at me, I have made up my mind to complain to my grandfather."

"Eaaah!"

"Emerald bracelet?"

"Wow!"

"So beautiful!"

"Na!"

"This is the lab key, you can play with it as you like!"

Seeing the jade bracelet, Xue Meimei's anger disappeared. She threw the key to Lu Fei and skipped away holding the bracelet.

When I came to the laboratory, I found an alcohol lamp from dozens of experimental equipment, and also found an asbestos net and a small iron plate.

The alcohol lamp was set up and lit, a portion of Deng Xinhua's blood was poured into the iron plate and placed on the rack for roasting.

As the blood temperature rises, the strong smell of blood fills the air.

Lu Fei kept stirring with a spoon. Gradually, the blood began to dry up and the color became thicker.

After ten minutes, the water in the blood is completely dried, turning into thin black dry flakes.

Then take off the iron plate and let it cool naturally.

On the other side, the asbestos net began to be burned on the alcohol lamp.

When the asbestos net reached a certain temperature, Lu Fei used tweezers to pick up a little bit of dried blood and placed it on the asbestos net.

After a few seconds, the color of the blood film gradually turned yellow, and a faint yellowish smoke rose.

Lu Fei twitched his nose hard. In addition to the smell of blood, there was also a faint fragrance in the smoke.

The source of this fragrance is orchid dew.

This is Lu Fei's experiment.

As for chemical experiments, Lu Fei knew nothing about it and could only use this stupid method to distinguish.

Although the method may be crude, it is effective.

After the orchid fragrance dew is taken by the human body, the essence will be deposited in the blood and it will take at least a month to be fully absorbed.

The pills Lu Fei prepared for Deng Xinhua contained a small amount of orchid dew.

Element.

Now I can smell the fragrance of orchid dew, which means that Deng Xinhua has taken the pills he prepared this month.

After testing the composition of the orchid fragrance dew, Lu Fei frowned.

It stands to reason that since they rely on their own medicines to maintain their lives, they would never dare to harm themselves.

If there are other experts helping them to suppress the poison of the money snake, then why do they still take their own pills?

Isn't this unnecessary?

Could it be that it was not Deng Xinhua and Jiang Hongyang who were secretly dealing with him?

If not them, who would it be?

Lu Fei closed his eyes and thought about everyone he had problems with, hoping to find a definite answer.

At this time, the door of the laboratory opened and Xue Meimei barged in.

Xue Meimei covered her nose and made a loud noise as soon as she came in.

"Wow!"

"What the hell are you doing, bastard? Why are you smoking so much?"

"Won't you turn on the exhaust?"

Xue Meimei turned on the exhaust and came to Lu Fei, rolled her eyes hard, and then closed the lid of the alcohol lamp.

Then he looked at the dried blood slices in the iron plate and said.

"What is this?"

"Blood!"

"impossible!"

"Don't fool me, I'm a top student in the chemistry department."

"Whether blood is dried naturally or baked, it is absolutely impossible to be black."

"Tell me quickly, what kind of shameful tricks are you doing?" Xue Meimei tilted her head and said.

Lu Fei originally closed his eyes slightly to think about the problem, but after hearing Xue Meimei's words, he suddenly opened his eyes.

"What did you say?"

"You think the blood in this iron plate is the wrong color?" Lu Fei asked.

Xue Meimei curled her lips and said.

"are you crazy!"

"This can't be blood, please don't make trouble, okay?"

"This is blood, and it's human blood. I dried it with an alcohol lamp."

"Tell me quickly, why is this color wrong?" Lu Fei asked.

"What?"

"Is this really blood?" Xue Meimei asked doubtfully.

"I swear, it's definitely blood."

"Tell me quickly, what's wrong?"

Lu Fei was anxious and angry, but Xue Meimei didn't take it seriously.

He picked up the tweezers and plucked the dried blood in the iron plate, blinked and stood up straight, and said to Lu Fei with a smirk.

"You're right, this is really blood!"

"But there's definitely something wrong with the color."

"Are you wondering what's wrong?"

Lu Fei nodded slightly.

"I want to know!"

"But I won't tell you."

"If you ignore me for three days, I will waste three days on you."

"I'll tell you the answer in three days."

"Bye bye!"

"Meimei, please stop making trouble, this is very important to me." Lu Fei said seriously.

"cut!"

"That's your business and has nothing to do with me."

"How can you tell me clearly?"

"I'll talk about it after I calm down," Xue Meimei said nonchalantly.

"The bracelet I just gave you is ice yellow sun green."

"Tell me the answer and give you a glass Zhengyang green bracelet." Lu Fei said.

Upon hearing the glass Zhengyang green bracelet, Xue Meimei's beautiful eyes were filled with sparkles, her hormone secretion instantly accelerated ten times, and she almost screamed with excitement.

Xue Meimei's eyes rolled a few times, she bit her lips and whispered.

"I haven't calmed down yet."

"Add a tourmaline brooch."

"make a deal!"

"Yeah

Geez, scoundrel, you are too open-minded. I like to work with smart people like you. Get it now! "

"Speak first. I will keep my word. I will never go back on my word if I tell you." Lu Fei said.

Xue Meimei thought for a while and said.

"No problem, I'm not afraid that you will regret it."

"You are right. This is indeed dried blood, but there is something very wrong with its color."

"Blood is rich in iron ions, which is also the root cause of blood color changes."

"The color of blood becomes darker in natural air because iron ions react chemically with oxygen in the air and are converted into iron tetroxide."

"This transformation causes the blood to turn dark brown."

"Even if the blood is dried or sun-dried, it will turn into dark brown at most, but it will never be black."

"Look at these dried blood flakes in the iron plate. They are darker than ink. Isn't there something obviously wrong?"

"unless"

"Unless what?" Lu Fei asked.

"Unless you add neurotoxins to it that cause the cells to break down, it can't be that color."

"ah!"

"What are you doing, bastard?"

"Let go of me, your scratching hurts me."

Xue Meimei was talking with gusto when her little hand was unexpectedly caught by Lu Fei and held in his hand.

Lu Fei's hand was so strong that Xue Meimei screamed out in pain.

Lu Fei quickly let go.

"I'm sorry, I was just too excited."

"Meimei, you just said that neurotoxins cause it to turn into this color. Can you test the ingredients of the toxins?"

Xue Meimei shook her sore little hand, feeling ashamed and angry.

He glared at Lu Fei fiercely, pouted and said displeasedly.

"Of course it's no problem. As long as it's there, I can test it."

"But why should I help you, a scoundrel?"

"Meimei, I didn't mean it just now. Please help me test it quickly. I will thank you very much later."
