Entertainment: My ex-girlfriend called the police, I filmed to pay off the debt

After reading the calculations for a while, Shen Han was suddenly enlightened, and he suddenly understood.

then.

He stands in front of the blackboard.

Chapter 520 Extract one gram of concentrated liquid, the concentration of which is one hundred times that of crude oil

He took the pen and pushed the hand aside.

Shen Han began to count.

He uses his mind, and these days, chemical experiments.

Through step-by-step recall, I know where the calculation is wrong.

Where, some important data is ignored.

The final result.

The calculation using the inverse function formula is consistent with the atomic weight of the chemical equation.

"Great."

"If the calculation is wrong this time, I will completely surrender."

……

Shen Han's voice still fell, and his consciousness went out of the system.

He stood in front of the laboratory table, looking at the alcohol lamp that exploded just now, and the concentrated solution that was not refined enough.

Shen Han faced the messy table.

He put on his gloves and swiped with both hands.

Put the broken alcohol lamps and any useless utensils into the trash can.

then.

Throw the gloves in, too, and seal the trash can.

Chemical experiments are fraught with danger, as well as rays entering the body.

Shen Han didn't care about these things, what he cared about was the dead sea, how did it swallow the giant ship?

He tidied up the table used for the experiment.

Take out a new alcohol lamp, and various reagents.

Put the various reagents, as well as oil, on the balance.

According to the calculated atomic weight, look at the weight on the balance.

Everything is ready and only owes the east wind.

Shen Han lit the alcohol lamp.

He put the reagents in test tubes filled with oil, and then baked them on an alcohol lamp.

The test tube was baked for ten seconds to observe the concentration of oil extraction.

The concentration meter is hung above the alcohol lamp, just aligned with the test tube.

drop by drop...

The concentration meter issued an alarm sound.

OMG!

One gram of concentrate is extracted, which is a hundred times more concentrated than crude oil.

Shen Han couldn't believe it, his eyes froze.

He opened his eyes wide, looking at a small, white liquid.

It is a bit far-fetched to say it is a white liquid.

It is a colorless, transparent soft solid.

He touched it with tweezers, and in an instant, it stuck to the tweezers.

Like a pearl, more like a dewdrop met with frost.

So cute.

Shen Han didn't dare to neglect, he wanted to increase the dose and replace the alcohol lamp with a kerosene stove.

Use a small iron bucket instead of a test tube, so the risk factor is reduced.

According to the increase of the amount of petroleum, the proportion of the reagent should be increased accordingly.

The gas stove was burning fiercely, and the smell in the laboratory was very unpleasant.

Shen Han hurriedly turned on the exhaust fan to diffuse the smell.

He turned his head to look at Song Xiaoying, who was still sound asleep on the sofa.

"what!"

"Didn't Song Xiaoying be sent away by me?"

"Why didn't she leave?"

"Is it a hallucination?"

"Or is it an illusion to send Song Xiaoying away?"

...... 0

While talking to himself, he felt that it was a bad dish, how could he forget this ancestor.

Staying for a while longer, maybe Song Xiaoying's life will be smoked, and she will not be able to take care of herself.

He was watching the chemical changes that occurred after the oil in the iron barrel entered the reagent.

While stretching out his right hand, he drew a circle in the air, and a blue light suddenly appeared from his fingertips.

With a flick of the finger, a blue dot of light shot out quickly.

Between moments.

A blue spot of light penetrated into the center of Song Xiaoying's eyebrows.

In less than [-] seconds, Song Xiaoying's body moved.

Then she whispered, "Ouch,"

"Why does my head hurt so much!"

"you're awake?"

Shen Han's voice didn't land, there was no shadow of Song Xiaoying on the sofa.

Chapter 521 Was it an illusion just now, or was it somewhere in the dark?

Does he feel like hell?

The secret room always tempts oneself, enter twice, look twice.

It's hard to tell the truth from the fake.

Song Xiaoying sent her off and came back again.Then, it disappeared completely.

Shen Han, who doesn't believe in gods or ghosts.

He believed it.

Say something bad and trick yourself.

Could it be, those wronged souls in the Dead Sea?

sizzle...

The iron drum was sizzling on the kerosene "[-]" stove, and the unpleasant smell gradually disappeared.

Accompanied by bursts of fragrance, tangy to the nostrils.

Shen Han feels that there is a door, according to calculation and ideal concentration.

The concentrated liquid extracted from petroleum is colorless and odorless, with an occasional faint fragrance.

Standing in front of the iron bucket, Shen Han was fully armed.

Put on a helmet, also wear a gas mask, a protective suit, also put on.

Shen Han, who has been a man for two lifetimes, is also afraid of being penetrated by rays like Madame Curie.

Time passed by every minute and every second, and he forgot whether Song Xiaoying had left or returned.

Still, it didn't go at all.

Focused on the concentration meter, and the thermometer.

I'm really worried, there will be a big explosion.

The temperature is getting higher and higher.

Suddenly, the concentration meter sounded an alarm.

drop by drop...

Several shrill bells rang.

Tell Shen Han that the concentration has reached the limit, and the temperature cannot be increased.

Turn off the switch of the kerosene stove, and the temperature in the iron barrel drops.

At this time, an electronically synthesized voice sounded in Shen Han's ear.

"The concentrated solution, the extracted concentration, is a hundred times that of crude oil."

This voice, like a blockbuster, exploded in Shen Han's ears.

He froze for a moment.

Can't believe my ears.

After a while, I came back to my senses.

Pick up the concentration meter, look and look.

"My God!"

"Concentrate, the extraction was successful."

"Third Uncle, no."

"Third uncle, the task entrusted to me has been completed."

"I'm so excited, third uncle, how can I tell you."

……

laboratory.

Indeed, there was only Shen Han alone.

It was a hallucination just now, or something in the dark, let Song Xiaoying accompany him.

The current Shen Han didn't care to confirm whether Song Xiaoying was in the laboratory.

He jumped up from the ground with joy.

Carrying extract, distilling bottle of concentrate.

I really want to chat with someone and share my mood at the moment.

dong dong dong...
