The villain in the book: My fiancée forced me to apologize to the male protagonist

Night, Wang family.

"Ran Ran went home today..."

Wang Haoran took a quick look with his clairvoyant eyes and found that Chen Rani was not in his room.

After searching, she was in Yun Ling'er's room.

At this time, Lin Xiaowei was also there.

The three of them were gathered around the table, as if they were talking about something important.

"Learn mathematics, physics and chemistry well, and you will not be afraid to travel all over the world!"

"So today I'm going to teach you chemistry!"

Yun Ling'er, an experienced "chemistry teacher", made various gestures while explaining.

"And in chemistry, one of the most basic knowledge points is yang production!"

"To stop tungsten... no, to produce oxygen!"

Lin Xiaowei and Chen Rani, two "good students", listened attentively with red faces.

After Wang Haoran opened the door and walked into the room.

The three people looked over——

"Ah, just right!"

"Brother Haoran, I just told them some steps of related chemical experiments. Come and help us practice it!"

Yun Ling'er happily greeted Wang Haoran over.

"Ling'er!" Wang Haoran touched Yun Ling'er's head and asked curiously.

"What experiment?"

"It's about oxygen production!"

"Oxygen production...Okay, I'm familiar with this, I'll help you!"

Wang Haoran nodded and agreed.

Before starting the experiment, it is natural to change into "appropriate" clothes.

Because they were too lazy to go out and get it, Lin Xiaowei and Chen Ranni both borrowed Yun Ling'er's clothes.

Because your body shape is different, it will definitely not fit you properly.

The sleeves and other places are loose...some places are baggy...but sometimes, ill-fitting clothes look interesting!

As for Wang Haoran, he naturally put on his "new clothes".

While everyone is changing clothes.

Wang Haoran took the time to ask -

"Ran Ran, I heard from Xiaoyan that someone in school confessed to you?"

Chen Ranni thought for a moment, then nodded: "...Well...it seems there is one."

"When class was over at noon, a boy gave me a rose and said he liked me."

"It was so baffling that I rejected him immediately!"

After Chen Ranni finished speaking, Yun Ling'er immediately took over the conversation: "Hehe, that man is miserable!"

"Brother Haoran treats Ran Ran as his treasure and wants to love you every day."

"But that boy actually dares to miss you!"

"Baby...where is it?"

Chen Rani, who had changed her clothes first, came to Wang Haoran, looking forward to it with shame and joy.

Then, after Yun Linger and Lin Xiaowei also changed their clothes.

Wang Haoran spoke.

"Ran Ran, you come first."

"Ling'er, Xiaowei, you guys are watching from the side, warm up first and learn from experience!"

""Um! ""

The three agreed.

……

The chemistry experiments soon began.

Teacher Wang stood behind him and taught Chen Ranni step by step to start the experiment.

"I'll teach you how to produce 'oxygen' by solid heating!"

"Remember, this experiment is divided into seven steps."

"Respectively -*"

"Check, install, fix, point, close, leave, extinguish."

"Check: check the tightness of the device; load: load the drug potassium permanganate; set: fix the test tube; point: ignite the alcohol content and heat the test tube; collect: collect the gas; detach: separate the gas collecting tube; extinguish: finally extinguish the alcohol lamp."

"do you understand?"

Chen Rani nodded nervously, "I understand!"

then.

Wang Haoran completed the first four steps in sequence, "cha↗", "zhuang↘", "dingv", and "dian".

This process takes a bit long.

Because the alcohol lamp was lit, Chen Rani's face turned red from the heat, and she began to complain in a nice voice.

But complaining is complaining, and now he is doing chemical experiments, so Wang Haoran is still strict with his requirements, without any tenderness or mercy.

Fortunately, Chen Rani persisted in completing the next steps.

"Collect", "leave", "xi"

……

End of experiment.

Wang Haoran carefully observed the "bottle mouth" of the gas collecting bottle and found that oxygen was flowing out of it.

This shows that Chen Rani successfully produced oxygen and the experiment was successful.

"Ran Ran, good job!"

"Hmm~"

Hearing the compliment, Chen Rani responded happily.

However, because the experimental process was too tiring, she began to rest helplessly.

then.

"Ling'er, Xiaowei, it's your turn!"

"Yeah!" The two of them walked over impatiently.

"Unlike Ran Ran, what you want to learn is to electrolyze water to produce 'oxygen'!"

Wang Haoran ordered:

"Before the experiment begins, you should prepare a small beaker and add an appropriate amount of water to it."

"As for the test tubes used to collect the gas, I will prepare them."

In fact, when Wang Haoran and Chen Ranni were experimenting, the small beakers of Yun Ling'er and Lin Xiaowei who were watching had already been prepared, as was the water used in the experiment.

But Wang Haoran was a little unprepared this time.

After searching around, he only found one suitable large test tube, but he had no choice but to take out two of the ten small test tubes instead.

Soon, the experiment began.

First, Wang Haoran slowly immersed the test tube in the water in the small beaker and started to energize it.

As for how electricity is generated, this involves basic knowledge of physics... magic ca generates electricity...

During the experiment, both Yun Ling'er and Lin Xiaowei became nervous.

The two intertwined their fingers and couldn't help but make sounds to encourage each other, hoping that the experiment would succeed.

On Lin Xiaowei's side, after powering on for a while, it was obvious that the water in the test tube was squeezed into the small beaker by the oxygen produced by electrolysis.

This caused the water level in the small beaker to rise.

"Xiaowei, look, drainage and gas collection, this phenomenon shows that you have successfully produced oxygen!"

"Ok!"

Lin Xiaowei responded with a sweet voice.

She naturally knew that she had succeeded in producing oxygen.

Although she was very tired, the success of the experiment made her extremely happy.

However, there was something wrong with Yun Ling'er's experiment.

"Brother Haoran~ I haven't succeeded in producing oxygen yet..."

"Let me take a look...it's probably because the current is not enough. I'll give you a new test tube!"

Let Lin Xiaowei, who had successfully "generated oxygen", go to rest.

Then, Wang Haoran began to focus on tutoring Yun Ling'er, who was not good at academics, to "generate oxygen".

Obviously, "electrolyzing water to produce oxygen" is a very simple experiment.

With the help of Wang Haoran, Yun Ling'er finally completed the experiment and successfully "generated oxygen".

She couldn't help but feel grateful.

"Brother Haoran, you are so kind~"

"It's good to know, you bad boy who doesn't like to study!"

Wang Haoran squeezed Yun Ling'er's warm little face -

"It's still early, let's do other experiments!"

"Ling'er, you come first this time!"
