I gave money to beggars and let criminals die in accidents

When the nanny handed the alcohol spray to Wu Zhuang, Su Chen sneaked up to check an invoice in the bag.

Due to time constraints, he only had time to see that the time written on the invoice was today.

From the time on the invoice and the newly unpacked alcohol spray, Su Chen immediately judged that the nanny must have gone shopping at a certain time today to buy alcohol.

Hence, Su Chen took this action.

Fortunately, everything is as expected.

Then the plan can go smoothly.

In Su Chen's plan, this small bottle of alcohol spray was about to become the trigger of an accident.

And that accident will create a perfect secret room in which Wu Zhuo will be killed!

Su Chen once again entered a new simulation space.

For this operation, he wants to implement the plan, the first practice, and kill Wu Suo!

After entering the simulation space, Su Chen immediately went out.

However, he did not rush directly to Wu's so-called villa, but took a taxi to the nearest high school.

The taxi stopped in front of the high school.

Su Chen got out of the car and glanced at the shops in front of the school.

In the end, my eyes stopped at a physical and chemical laboratory equipment store.

He walked straight into the store.

After about 5 minutes.

Su Chen came out of the shop.

In his hand was a big bag full of things.

He took a taxi again and headed back to his residence.

After returning to his residence, he came to the desk with his bag.

Remove the computer and everything from the desk, and wipe the desk carefully with a wet wipe.

Then, I started to take things out of the bag.

He first took out a test bench for chemical experiments and carefully placed it on the desk.

Then, he took out a bunch of bottles and various rubber tubes.

Finally, an alcohol lamp was taken out and placed on the test bench.

After taking out all the things, he set up the test bench and put all the reagent bottles and experimental bottles in place.

Now everything is ready to start.

He wants to make a chemical reagent.

This reagent is the key to his plan

Su Chen thought for a while, and in order to prevent mistakes, he took out his notebook and wrote down the formulas needed during the experiment:

CH3NO2+CS2?→KSC=CHNO2→CH3SC=CHNO2 (催化剂C2H5OH)，二步收率48.5%

The first step is to use nitromethane and sulfur dioxide to catalyze the reaction in ethanol to obtain dimethylthio, and then add dimethyl sulfate to filter and place to obtain nitroethylene.

Su Chen clamped the yellow crystal in the reagent bottle he bought into the reagent bottle with tweezers, then poured 2 ml of sulfur dioxide, and finally poured ethanol and stirred.

After standing for a while, pick up another bottle of gray object and pour it in, let it stand for a while.

Then, Su Chen continued to write down the experimental formula in his notebook, and then proceeded according to the formula...

... (too complicated, omitted)

15 minute later.

Looking at the pink lens in his hand, Su Chen knew that there was one last experiment to succeed.

He wrote down the last formula again in his notebook:

（CH3）2NCH2——CH2SCH2CH2HNC=CHNO2HCL

According to the formula, Su Chen mixed the pink crystals of methylamine methanol and dichloromethane, and then heated it on an alcohol lamp.

After the lens melted, Su Chen carefully added dichloromethane into it using a test tube in order not to come into contact with oxygen.

Finally, cool and stand, filter and dry, add methanol again, and vacuumize.

In the end, he finally succeeded in getting his target, ranitidine hydrochloride.

Looking at the fine crystalline lens in the reagent bottle in front of him, Su Chen said with emotion:

"It's still the same sentence, learn to physicalize, and you will not be afraid to travel all over the world! This is called knowledge is power!"

Su Chen is very satisfied with the results in front of her.

Now, there is only one last step left to complete the preparations.

Su Chen took out the last item from the bag.

This is a bottle of alcohol spray.

And it is exactly the same as the alcohol spray bought by Aunt Wang, the nanny.

Su Chen placed the alcohol bottle far away from the test bench.

Take out a thin needle tube and draw out more than half of the alcohol inside, leaving only the bottom of the bottle.

Next, he produced a long test tube with an alcohol spray on one end and a test tube on the other.

He heated the test tube over an alcohol burner.

As the alcohol heated, the air in the alcohol spray was drawn down the long test tube.

Soon, there was nothing but alcohol in alcohol sprays but a vacuum.

Then, Su Chen turned the alcohol spray upside down.

Air is then injected into the bottom with a needle.

Back to normal when done.

I saw that the alcohol spray in the alcohol spray bottle was squeezed to the upper layer at this time.

It looked exactly the same as when the bottle was full.

Su Chen knew that only when the spray was pressed could she find out that there was actually only a little alcohol in the bottle.

Finally, Su Chen evacuated the ranitidine hydrochloride crystals made in the experiment just now, and injected the alcohol spray.

The component of alcohol is ethanol, and ranitidine hydrochloride is soluble in ethanol.

So the ranitidine hydrochloride melted away in the alcohol spray bottle very quickly.

The alcohol spray at this point looks exactly like normal, without any difference.

After finishing all this, Su Chen carefully put the alcohol spray face up in the bag.

Everything is ready, the next thing is to start the action!

Chapter 43 Wu So-called Died in a Secret Chamber

9am.

Su Chen took a taxi to the supermarket where the nanny entered.

Since Su Chen entered through the back door, he passed the cash register first.

At this time, he heard a conversation at the cash register.

A cashier spoke to a young man standing next to him:

"Is this your first day of cashier practice?"

The young man nodded.

The cashier patted him on the shoulder encouragingly.

Then she looked at a watermelon on the table and complained:

"That person just now was really serious. He took a watermelon, but in the end he thought it was too expensive."

"You're fine for now, why don't you go and put the watermelon back!"

Without saying a word, the young man picked up the watermelon and walked inside.

Seeing this scene, Su Chen suddenly became thoughtful, and a plan emerged in his heart.

He made a beeline for the aisle of alcohol spray.

Stop by the shelves.

He recalled carefully that the nanny took the alcohol spray from the sixth row in the third row.

Soon, he found his target.

He directly picked up the bottle of alcohol spray, put it in his shopping cart, and left the area.

He pushed the shopping cart to the area next door selling daily necessities.

At this time, there is a woman shopping here.

Her shopping cart was parked not far in front of her.

Su Chen observed that her shopping cart was very full.

Looks like it should be billing soon.

Su Chen quietly approached her shopping cart.

While the woman was not paying attention, he put the bottle of alcohol spray he made in her shopping cart.

From then on, Su Chen followed the woman all the time.

In order not to attract attention, he filled the shopping cart along the way, and it seemed that he was really shopping.

The only thing that gave Su Chen a headache was that this woman seemed to be endless, walking back and forth in the shopping mall, but she just didn't go to check out.

Su Chen looked at the time, it was already 9:58.

It's less than 10 minutes until the babysitter's arrival.

Su Chen shook her head.

He knew that the first experiment failed.

It never occurred to him that the failure this time was due to a trivial matter.

He had thought about countless possibilities of failure before, but he hadn't thought of this.

Sure enough, accidents often start with small things.

Su Chen sighed and left the simulation space with a thought.

......

Second experiment.

Su Chen entered the new simulation space again.

He again took the sixth alcohol spray in the third row.

But this time he didn't choose that aunt.

Instead, came to the cash register.

There was already a long queue in front of the cash register.

Su Chen entered the line and was at the end of the line.

Soon, a girl in her twenties came and came behind Su Chen.

Su Chen watched secretly from the corner of his eye.

He found that the girl's shopping cart was full of snacks.

Su Chen decided that it was her.
