Comprehensive Comics: Playing as the King of Heroes in the Final Beginning

Children always like to poke and poke their fingers randomly.

Therefore, it always happens that in some parks, there is a hole in the metal block on some facilities, and it cannot be pulled out after inserting a finger.

In general, if you want to pull your finger out, a common way is to apply some lubricating liquid such as soapy water.

In this way, the contact surface between the finger and the metal of the card owner can become smooth, making it easier to pull the finger out.

Therefore, if fingers often get stuck in a hole in the future, this method is often used.

However, not all of these snap-in methods can be easily pulled out using methods such as soapy water.

On the contrary, the situation may become more serious and the jam will become tighter due to the addition of liquid.

So, what is going on in this situation?

In this case, the hole is inserted, and the inside of the hole is closed.

The previous one could use liquid to lubricate the finger to make it easier to pull it out, but the finger was stuck in the ring.

But now, if you add liquid, it will get stuck tighter - that's a hole.

Just like the former, you just stuck your finger on the ring owner, while the latter is equivalent to your finger being stuck in a reagent tube.

In this case, adding liquid may fill the space between your finger and the inner wall of the reagent bottle.

After all, the fingers are not completely smooth, and there are still slight gaps in contact with the inside of the reagent bottle itself, allowing air to enter.

If liquid is added, these gaps will be filled and the air will be squeezed out, which will make the adsorption of the reagent tube wall and hands stronger.

It's like two pieces of glass stacked together. There are two situations: one is dry glass stacked together, and the other is stacked together with water added.

In both cases, which one is easier to separate the glass?

The answer is of course the former.

In the latter case, it is because the gap between the glasses is filled with water, so that there is no atmospheric pressure between the two pieces of glass, and thus they are squeezed together by the atmospheric pressure on the other side exposed to the air.

Insert your finger into the reagent tube and moisten it with water, which is similar to this situation.

If it is inserted too hard, the air inside will be squeezed out quickly, and the air will not be able to flow back, which will cause the air pressure in the reagent tube to become very low.

In this way, the finger will be sucked by the pressure of atmospheric pressure and cannot be pulled out.

This situation is similar to that of a vacuum suction cup.

The suction cup sticks to the smooth wall because the gas is pressed out, causing the air pressure difference to stick.

If you pull the suction cup hard, it may seem that you can pull it out to a certain extent, making it appear that there is a space between the center of the suction cup wall and the wall. However, due to the air pressure difference, when you release your hand, it will suck back..

In the same way, after the finger inserted into the reagent tube is lubricated, even if it can be partially pulled out, it will eventually be sucked back inside due to the difference in air pressure, allowing it to slide back in again.

If it is pulled out violently, the result may be injury. so——

"It's really okay, great, President~"

A cute girl with reddish-brown slightly curly hair said with a sigh of relief.

She is one of Sona's dependents - Xunba Bing, and suddenly contacted Sona to say that she The artifact was stuck and could not be removed, so I asked her to help ask how to remove it.

The artifact of Xunba handle was a knife. The so-called jam was that the knife was suddenly sucked into the scabbard and could not be taken out..

The reason for this is actually that this artifact has a secret skill, which he did not tell, hoping that he could study it on his own.

And this secret skill is that the card owner's sword actually has a special skill formed inside the scabbard. Magical magnetic attraction.

As long as the user injects more magic power into it, and the internal pressure becomes stronger to a certain extent, the sword will pop out like lightning, as if it is accelerated by electromagnetism.

Then, as long as the user uses this With such speed, you can use unimaginable sword-drawing slashes, which are so powerful that they can tear apart space.

"President, please also thank Teacher Bai Yue for me."

""Yeah."

Cang Na responded with a smile.

If you look carefully, you will find that her smile is very forced. She is not forcing a smile, it should be said to be similar to a dry smile, because she is in a particularly bad situation, and she is also in trouble with the sword of the patrol handle. The card owner is somewhat similar.

Therefore, she is also very nervous. The nervous patrolman suddenly wants to thank her for the hug.

0 Ask for flowers. This child is often like this.

If he hugs her suddenly, he will realize that she is There was something wrong with the chair she was sitting on.

It was like she was not touching the chair at all, but was sitting on an invisible transparent air cushion, which was isolated from the chair.

In fact, the air cushion was a magic like optical camouflage applied to it. , thereby hiding his true face.

And this true face is known to Shinra Chunji who is nearby.

"By the way, President, is this a new product you brought from the devil world?"

Hua Jietao, a girl who is also one of the president's family members, said curiously.

Because the president was shaking all the time, as if he was enjoying that kind of massage chair, and it looked very comfortable. (To read exciting novels, go to Feilu Novel Network!)

"Can you let me sit down and try it?"

"no!!!"

The president refused, and his reaction was too extreme.

"I, I understand."

Hua Jiitao shrank.

Suddenly, a huge magic circle opened. It looked like it was released by the president, because the magic wave came from the president, and then everyone was moved to the training space. Here we come.

So, does the president want to personally see how far these people have mastered the artifact?

"Let me see how far you have mastered the artifact."

Such a voice reached the ears of Hua Jietao and other girls. They looked around in confusion, but did not see the owner of the voice.

Yes, this voice does not know how to do it. It's Mr. Bai Yue.

Maybe he is in other places and can watch here directly through magic.

"Okay"*nSo

, a large number of mechanical monsters appeared in this training space. I heard that they were developed by Miss Sigwila.

In the blink of an eye ,——

"President, be careful!"

Suddenly there was an attack that deflected and flew towards the president.

However, the president didn't seem to hear it. He seemed to be distracted, distracted, or lost his mind.

And the vice president was the same.

Boom——!

It hit, no, it didn’t hit.

However, some disguise was exposed, and everyone was stunned for a moment...
