Douluo's genius

"Uncle, are you quite powerful?" Fang Mingyu asked Qian Duoduo.

Qian Duoduo said: "It's quite powerful. What's wrong? Why do you ask?"

Fang Mingyu stepped forward, opened the stone slab above, and put the battery inside back into his belt.

Then he took out a pack of matches from his belt, turned to Qian Duoduo and said seriously: "Uncle, what is your strength? If you don't tell me, it will be difficult for me to continue.

This experiment is really dangerous, and I don't want to see you die in front of me. "

"Who do you look down on?" Qian Duoduo pointed there and said, "Do you think this thing can hurt me? I am also a defensive soul master after all. You can do it with ease. Even if I die, it has nothing to do with you."

"Okay." Fang Mingyu handed the match in his hand to Qian Duoduo.

Qian Duoduo looked at the match in his hand and asked strangely: "What are you doing?"

Fang Mingyu reversed his serious expression and said with a smile: "Uncle! Don't you want to see something interesting? I'll show it to you now! And if you light a match inside, there will definitely be an explosive surprise!"

"All right!"

Qian Duoduo walked towards there, and when he was about to light the match, he was suddenly stopped by Fang Mingyu.

"Wait a minute, uncle!"

Qian Duoduo turned around and asked, "What's wrong?"

Fang Mingyu hurriedly retreated back for 15 meters. He touched the ground with his hands to create a stone wall and shouted to Qian Duoduo: "That's enough! But I also want to suggest you, uncle, release the weapon first." Soul, protect yourself! This is really no joke!"

"I told you there's no need!"

Fang Mingyu faced Qian Duoduo, clasped his hands and said, "Then may God bless you! Amen!"

Qian Duoduo looked at Fang Mingyu and hid his body behind the stone wall.

Somewhat strangely, he opened the stone slab and looked inside.

Nothing at all.

Is this thing really so dangerous?The child was so nervous.

But it’s all air!How could the air be a danger to me?

And what does he mean by "May God bless me"?

Sigh... Today's children really don't understand what they are thinking more and more.

Qian Duoduo sighed, wondering how this child's brain circuit grew?Then he lit a match and threw it in.

At 0.11 seconds, Qian Duoduo broke into a cold sweat.

At 0.26 seconds, Qian Duoduo immediately released Wuhun Black Dragon Shield.

At 0.79 seconds, Qian Duoduo’s martial spirit was successfully released!His nine soul rings, two yellow, two purple and five black, also rose at the same time!

At 1.00 seconds...

"Boom!!!!"

Fang Mingyu covered his ears and hid behind the stone wall. Just by listening to the explosion, he understood how big the explosion was!The huge vibration can be felt here!Even the airflow from the explosion blew his hair off!

Fang Mingyu pointed his forehead, left shoulder and right shoulder with his finger and said: "Uncle, may you enter the Western Bliss, Amitabha!"

At this time, there was suddenly a sound of heavy footsteps behind him, and a big hand directly broke through the stone wall.

The big hand pinched the back of Fang Mingyu's neck and lifted Fang Mingyu up like a little chicken.

The owner of the big hand turned Fang Mingyu to face him.

And there was a lot of money at this time.Although he was not injured, all his clothes were burned.A very strong upper body was exposed. The whole body was covered in dust, and half of his hair was burned off!

Fang Mingyu covered his mouth and tried not to laugh.

If he hadn't seen the nine soul rings under Qian Duoduo's feet, he would have laughed now.

Damn it!This uncle is actually a titled Douluo!You can’t laugh, you can’t laugh, it will make you feel cold if you laugh!

"What the hell is going on! Why did it explode? And it exploded so hard!"

Fang Mingyu suppressed his smile and said, "Didn't I tell you everything? Explosive surprises are very dangerous!"

Qian Duoduo looked very excited and said: "Then you are really a surprise! I was so surprised that my hair was burned!

Do you know how difficult it is for a soul master to reach my age and still have such thick hair? ! "

Fang Mingyu suddenly smiled and said: "Uncle, tell me, is this enough? Is it interesting?"

Qian Duoduo, who seemed very excited just now, suddenly fell silent.

Qian Duoduo confirmed that there was nothing there just now!If anything, it's just the grass below and the air in between.

The grass on the ground can indeed burn, but it is absolutely impossible to produce such a big explosion.

As for the air... Just kidding, humans have been living on this continent for so long. I don’t know how many years have passed since the beginning of using fire. If the air can be ignited, how can there still be humans now?

Qian Duoduo put Fang Mingyu down, stroked his beard and pondered, and said while thinking: "I can't figure it out! I can't figure it out no matter how hard I think... why there is such a big explosion when there is nothing there."

Fang Mingyu looked at Qian Duoduo's thoughtful look, raised the corners of his mouth slightly and said, "I know, I can tell you."

Qian Duoduo's eyes suddenly lit up, a pair of big hands directly grasped Fang Mingyu's shoulders, and said loudly: "Do you know how this was formed? That's right, you did it, how could you not know? Tell me quickly! "

Qian Duoduo has lived for so long, and he has dedicated most of his life to the soul guide.

In order to study soul guidance devices, he went to many places to look for materials.Naturally, I have seen a lot of things.

But the longer he studied, the more he understood that the further improvement of the soul guide was closely related to his own knowledge.

And he dared to say that he had put all the knowledge about soul guidance devices in Douluo Continent into his head.He even knows a little bit about the soul guidance devices in the Sun and Moon Continent.

But it was impossible for him to learn the knowledge of soul tools in the Sun and Moon Continent.

So now he wants to improve his knowledge again, which can be said to be as difficult as climbing to the sky.

Unless you have researched something yourself.

But what is researched is easier said than done.

But now, a brand new knowledge suddenly appeared in front of him.

It couldn't imagine this phenomenon at all, and it had no idea how it happened.

But the child in front of him knew that his crazy thirst for knowledge had already occupied his brain!

Fang Mingyu said: "Then if you say you are not interested in this, will it be of any use to you?"

Qian Duoduo was slightly stunned, and coughed twice in embarrassment: "Okay, okay, you win. You can take whatever you want from the stall.

So tell me how this came about! "

…………

The principle of electrolyzing water.

Adding an electrolyte conducts electric current and electrolytically dissociates water molecules.The negative electrode of the DC electrode releases hydrogen gas.

The positive electrode releases oxygen.

Hydrogen and oxygen can be collected using the drainage gas collection method, with a volume ratio of 2:1.

The above-mentioned electrolyte can be an ionic compound that is a combination of strong acid and strong base, such as sodium chloride. However, in order to avoid the generation of chlorine gas at the anode, sodium hydroxide should be used as the electrolyte.

Hydrogen explosion.

Hydrogen may explode when ignited in the air. According to theoretical calculations, the explosion limit of hydrogen is 4.0% to 75.6% (volume concentration).

This means that if the volume concentration of hydrogen in the air is between 4.0% and 75.6%, it will explode when encountering a fire source.

When the hydrogen concentration is less than 4.0% or greater than 75.6%, it will not explode even if it encounters a fire source.

Sulfuric acid battery.

For sulfuric acid, a lead plate filled with sponge-like lead is used as the negative electrode, a lead plate filled with lead dioxide is used as the positive electrode, and 22 to 28% dilute sulfuric acid is used as the electrolyte.During charging, electrical energy is converted into chemical energy, and during discharge, chemical energy is converted into electrical energy.

Hehe, strange knowledge has been added again.
