A classic scene in a martial arts drama: A martial arts master sat cross-legged and meditated, his eyes closed, and a trace of white smoke came out from his head.

This way of expression embodies the mysterious and abstract internal strength, allowing the audience to intuitively see at a glance that the character is practicing, and the skills he practices are very awesome, demonstrating his profound and powerful internal strength.

Now, Xu Wentang is going to reproduce this classic scene.

The biggest question is how to make smoke come out of the head and where does that smoke come from?

"Smoke can be divided into two categories: dust, mist, or a mixture of the two."

"Dust is extremely tiny particles, such as smoke from tobacco burns; mist is liquid vaporization, such as water vapor, dry ice."

Xu Wentang thought about everything he could think of and thought that the best prop should be dry ice.

Dry ice is solid carbon dioxide.

The application of carbon dioxide can be said to be very widespread.

For example, dry ice fire extinguishers.

Carbon dioxide has a higher density, about 1.5 times that of air. Under normal pressure, liquid carbon dioxide will vaporize immediately. Generally, 1 kg of liquid carbon dioxide can produce about 0.5 cubic meters of gas.

When dry ice turns from solid to gas, it absorbs a lot of heat, causing the temperature of the surrounding air to drop very quickly. When the air temperature drops, it causes the water vapor to liquefy and releases heat, and it becomes small droplets, which is the fog we see with the naked eye.

"With the source of smoke, a guide device is also needed."

The smoke is diffusing and is not controlled. As long as it is released, it spreads around without guidance, and it will inevitably smoke everywhere. There will be no scene of smoke only on the top of the head.

"I have to buy some tiny hoses."

Xu Wentang thought about various details and felt that as long as he got dry ice and tiny hoses, it would be no problem to shoot the effect of "smoking over the head".

Do it when you think about it.

However, I can't continue before I even started.

The reason is that there is no money.

It costs money to buy dry ice, and it costs money to buy small hoses.

Xu Wentang is still a senior high school student and has no source of income. The money in his wallet is mainly meal tickets. The pocket money available for disposal is pitifully small, and it is only enough to buy some small hoses.

Of course, aren’t there any parents? I ask them if they want it!

This won't work either.

The Xu family’s house was bought with a loan and was still paying the loan. Xu Wentang and Xu Wenjuan also cost a lot of money to go to school, and the family’s daily expenses were all supported by the little salary of their parents, and they barely maintained a balance.

If one day grandparents and grandparents fall ill one or two, the Xu family will inevitably have financial burdens.

Alas, a penny can't kill a hero!

Thinking of this, Xu Wentang's thinking gradually spread. He couldn't find a solution, but suddenly he thought of a major omission!

His plan is like this - shoot a realistic and fake video to upload it to the class group (the only social circle), and then earn popularity from classmates.

However, his classmates did not know the "Healing Heart Sutra".

"Everyone clicked on my video and saw me sitting cross-legged and smoking above my head. What was my first thought?

It must be... what skill Xu Wentang is practicing? Why is it smoking? Could it be that he is obsessed with it?

Instead...wow, Xu Wentang has practiced the "Healing Heart Sutra", which is so awesome! This shocking effect."

Thinking of this, Xu Wentang found that this matter was much more complicated than he thought and the operation was quite difficult.

"Don't worry, if you have any problems, come one by one."

Xu Wentang sorted out his thoughts and listed the problems that need to be solved in order.

The first step is to solve the problem that students do not know about the "Healing Heart Sutra";

The second step is, even if the students know the "Healing Heart Sutra", how can they make them realize that I am practicing the "Healing Heart Sutra" as soon as they see the fake video;

The third step is to solve the problem of capital shortage.

"Oh, fraud is also a technical job." Xu Wentang calmed down and thought about it. His ideas came to his mind one by one, and he removed them one by one, and the corners of his mouth gradually rose up.

After a moment, Xu Wentang came up with a plan and came up with a solution to the first two problems.

Pick up your phone and turn on the camera.

Xu Wentang focused on his palm and used the black sand hand. Then the camera focused on the black hand and took a photo.

Then open the "Healing Heart Sutra", turn to the first article, and take a photo of one of the pages, and the focus happens to be the description of the text "Smoke raised above the head".

The two photos are put together.

Mark a line of text: Encourage with you, and the mysterious exercises help me to practice the strongest iron sand palm within seven days!

Xu Wentang looked at the pictures and texts and felt that there was no problem, and uploaded them to the class group.

At this moment, the class group is quite quiet and no one is filling it with water.

Waited for nearly a minute.

Sun Dapeng: What’s the thing? This black hand is an iron sand palm?

Zhu Dawei: I don’t understand. Iron Sand Palm was originally named Black Sand Hand. This is how I became successful in my practice.

Ban Cao is here: Xu Wentang has trained the iron sand palm to great success!

One day's love: What kind of martial arts is so awesome?

Huo Qianqian: Same question.

Zhou Mingshan: Same question.

...

Xu Wentang was waiting silently, and the atmosphere was almost inflamed. He announced the name of the martial arts: "Healing Heart Sutra". The martial arts passed down by a relative and friend's family were specially requested by my father for me.

Next, the group talked about the "Healing Heart Sutra". Gradually, some students posted public @ or sent private messages to Xu Wentang, hoping that he could share this technique.

Of course, Xu Wentang cannot share it. Once the exercises are leaked, they may reveal their feet. No, they should definitely reveal their feet, because the Heart Sutra is not an auxiliary exercise of the Iron Sand Palm.

"With this preparation, I can safely and boldly create fake videos to upload."

The problem is back to money.

"Cousin, do you have other magazines here?" Wang Hu shouted at him.

At this moment, the fat man was lying on the chair on the balcony, crossing his legs, looking at the swimsuit photos of the models in the magazine happily, saliva flowing.

Xu Wentang was speechless, suddenly his eyes flashed and asked, "Fat Hu, how much money do you have?"

"About...13 yuan, why?"

"You go to the convenience store downstairs immediately and buy a pack of cigarettes. Which one is the cheapest to buy," Xu Wentang said in a row.

"Cousin, when did you start smoking?" Wang Hu sat up in surprise.

"Stop talking nonsense, go and buy it." Xu Wentang made up his mind and immediately drove the guy out of the house as long as he dared to say a word.

Wang Hu hesitated for a while and went.

Go downstairs and go upstairs.

"I bought cigarettes, Tashan, which is 8 yuan a pack, is the cheapest." Wang Hu handed over the cigarette, held it in for a while, and said, "Cousin, smoking is harmful to health, please take it easy."

"I know smoking is harmful to health, so I bought it for you to smoke." Xu Wentang smiled.

"What?" Wang Hu blinked, a little confused.

"You wait for me here for a while." Xu Wenhu turned around and went to the next house. He was very lucky and borrowed several small hoses, which were more than two meters long.

“The materials are fully prepared.”

Xu Wentang was very excited and used tape to wrap five small hoses together, the front end spread out, and the other end was tightened.

Then, he handed the lighter to Wang Hu and said, "Light a cigarette, suck it up, and then spit the smoke into these hoses."

"...Why?" Wang Hu was confused and looked puzzled.

"You will know right away, do what I said." Xu Wentang fixed the camera while speaking, sat cross-legged on himself, inserted the dispersed front end of the hose into his hair from his mind, and the rest was blocked behind him.

"Fat Tiger, blow the smoke quickly." Xu Wentang put his hands on his knees, pinched his fingers, closed his eyes, and looked solemn.

Seeing this, Wang Hu was completely confused, but he was very curious about what his cousin was doing, so he did as he did.

"Ahem cough cough..."

Wang Hu smoked the first breath of cigarette in his life, almost coughed up tears, and blew the smoke into the hose, and the smoke rushed down the hose to the other end.

After a while, the smoke blew out of Xu Wentang's success!
