Chapter 259 Simple Iron Ball Test

(The explosive change challenge starts today. Tianya’s challenge is 15,000 words. I look forward to your support. Monthly tickets, likes, recommendation tickets. Thank you.)

This is a "knowledge field" that everyone has never heard of. Atmospheric pressure, aura pressure, etc., plus a series of calculation methods such as "aura flow", made everyone even more confused.

Huang Mingshan looked at Zhang Hao, who nodded slightly. Huang Mingshan immediately said to everyone: "Let's do an experiment, and use the experiment to explain the situation."

"First we said rock. Now we put a rock on the ground. Is there pressure under the rock?"

Everyone nodded.

Huang Mingshan picked up another stone, "The pressure at the bottom has increased, right?"

Huangming Mountain piled up stones one by one, and everyone suddenly realized. Huang Mingshan proposed the concept of pressure: "The ratio of the upper pressure to the pressure area is called pressure. Taking the stone in front of us as an example, the pressure is related to the weight of the upper stone and the lower area under the force.

Let's talk about water again, intercepting a piece of water alone, is it similar to this stone? It's just that the stones were replaced by water, and the ground was replaced by the bottom of the lake. "

Everyone nodded, but they still didn't quite understand what this had to do with atmospheric pressure.

But Huang Mingshan had already asked his apprentices to take out two hollow steel hemispheres from the research base, the size of a watermelon, with a handshake at the bottom, which could be grasped by hand or tied with a rope. There is also an air extraction hole in one of the hemispheres.

Huang Mingshan showed you the hemisphere. The interface between the two hemispheres is as smooth as a mirror, and a layer of soft fish gelatin is slightly applied to assist the seal.

Huang Mingshan opened and closed one hemisphere in each hand, of course the two hemispheres cannot be closed. After showing it like this, Huang Mingshan's face became serious, he closed the two hemispheres again, and said to Liu Dingshan: "Senior, please look, I will put these two hemispheres in the water now."

The combined hemispheres were put into the lake water, but they did not separate after entering the water, so they quickly sank to the bottom and fell into a piece of aquatic plants, startling a small fish fry.

Huang Mingshan made an inviting gesture: "Senior, please open the two hemispheres from the bottom of the water. Hold the handles at both ends with both hands to see how much power is needed.

Let me explain in advance, I can't even open this steel ball when the water depth is two meters. And now it's almost five or six meters deep. "

Liu Dingshan didn't ask, he dived into the lake without hesitation, and held both ends of the steel ball under the lake with force, but he didn't pull it apart for the first time. A little more force, still did not pull. In the end, it took a lot of strength to pull the hemisphere apart.

But there was a bang under the lake, a little turbulence appeared, and a little mud from the bottom of the lake was rolled up.

Liu Dingshan surfaced, he didn't say anything, he just separated the two hemispheres to observe, then closed them again, and then entered the water to pull them apart. After doing this several times, Liu Dingshan pondered: "Is this... water pressure?"

"Yes, water pressure!" Huang Mingshan nodded, "And as the depth of the water increases, the pressure will increase."

Liu Dingshan experimented a few more times, and the rest of the masters jumped into the water one after another to do experiments. In the end everyone was a little surprised. This thing pokes really simple, but amazing nonetheless.

After more than an hour, the steel ball returned to Huang Mingshan's hands again, and Huang Mingshan said to everyone: "Fish live in the water, so what is there around us?

There are two. One is the air, the air we breathe! "

As he spoke, Huang Mingshan took a deep breath, and then pointed to the white clouds in the sky, "The white clouds are floating in the air, like those floating weeds in the water.

And the second is aura. The source of spiritual energy for our daily practice is all around us.

Now, I close the two hemispheres and take the air out of them. Everyone said, what will happen? Senior Liu, can I trouble you again, use a spell similar to dragon sucking water to suck out the air through this air inlet. "

Liu Dingshan was overwhelmed by this new knowledge a long time ago, without saying a word, he evacuated the air in the steel ball and closed the valve of the air extraction hole.

Huang Mingshan said with a smile: "Now, senior, please open these two hemispheres."

Liu Dingshan tried hard with both hands, but also failed to open it the first time. It wasn't until faint blue veins emerged in both arms that the steel ball was finally pulled away. There was a violent sound of "Bo'er" in the air.

Liu Dingshan repeated it several times, thoughtfully: "This pressure is even greater than the pressure under the water just now. I reckon that if we only calculate the strength of flesh and blood, we need the strength of the late Jindan stage to break this pressure." The steel ball was pulled away. Is this an atmospheric stand?"

Huang Mingshan nodded, "Yes, this is atmospheric pressure. According to our experiments, atmospheric pressure, or pressure to be precise, is equivalent to the pressure at a water depth of 15 meters.

As with the air, so with the aura. It's just that we haven't calculated the pressure of the aura yet. But I don't think it will be too weak.

Senior, a small steel ball can withstand such pressure, so if the steel ball is increased to a diameter of ten meters, one hundred meters, or one thousand meters, how much pressure will it bear? "

Liu Dingshan's complexion changed a little. He was silent for a while, then said leisurely: "Sure enough, manpower is exhausted. Heaven and earth... are the greatest."

But at the next moment, Liu Dingshan suddenly stretched out his hands, looked up at the sky, and smiled: "I saw it, I saw the direction of the late stage of Transformation God. Haha..."

The roar was like the roar of the sea waves, the high-altitude floating clouds collapsed, and the sky was as blue as washing. The laughter was still spreading, Liu Dingshan's aura was rising steadily, and the heavy pressure made Zhang Hao feel extremely difficult to breathe.

The surrounding spiritual energy gathered, and then... collapsed! Yes, compared with the breakthrough in the Nascent Soul stage, the spiritual energy of the whole world has collapsed instead of gathering aura at all.

Zhang Hao even saw water-like fluctuations in the aura around Liu Dingshan, and the aura was almost as real as it was.

Suddenly a white rainbow appeared from above Liu Dingshan's head, piercing the sky. The spiritual energy hovered in the sky, and gradually appeared a vortex, and rainbows and rays of light appeared around.

But almost at the same time, lightning also appeared! Small lightning bolts, like naughty little snakes, shuttle in the vortex. But soon the little snake turned into a poisonous snake, crazy and ferocious.

Liu Dingshan's complexion changed drastically: "Lying on the grass, how could there be thunderstorms!"

Zhang Hao was relatively calm, the only shock was Liu Dingshan's breakthrough. Zhang Hao immediately asked people to build iron pillars, iron frames, etc., and iron cables were connected to the top. Iron cables, iron frames, etc. are all buried in the ground, and even introduced into the artificial lake next to it.

Seeing Zhang Hao's busyness, Liu Dingshan was even more confused. But he didn't feel malice, what he felt was deep concern, and the breakthrough in practice couldn't be stopped at all, so he could only continue to practice.

The spiritual vortex in the sky was like a vast ocean tide, and the center began to fall, following the white rainbow above Liu Dingshan's head. At the same time, a large number of lightning flashes frantically.

Finally, a bolt of lightning fell along the white rainbow, but soon fell on the iron chain, and the crazy thunder and lightning crashed into the ground and the lake along the iron chain. Mud splattered and water splashed.

Then there was a clear and violent sound between the sky and the earth, as if the sky was torn apart. The crisp sound made my heart tremble.

However, this is just the beginning.

The vortex of spiritual energy finally landed on the top of Liu Dingshan, and the crazy lightning was taken away by iron pillars, iron frames, iron cables and so on.

Everyone was amazed, the gap between the iron cables was obviously huge, but Lightning turned a corner and fell on the iron cables, turning a blind eye to Liu Dingshan below.

Visions come and go quickly, after all, it's just a small grade breakthrough, not a promotion.

Liu Dingshan was suspended in the air, his whole body was full of majesty, Zhang Hao felt that he couldn't get close. As for Liu Dingshan, he was observing those iron chains. Many iron cables have already melted.

Liu Dingshan's eyes were full of curiosity and surprise. I was a little flustered when I found out that I had triggered the tribulation thunder——I didn't do anything outrageous. Then he was confused by Zhang Hao's methods.

It took Liu Dingshan a long time to gradually restrain his aura, and a bright smile appeared on his face. "It's the late stage of transformation, Zhao Kai is in the middle stage of transformation, Zhao Ying is only in the early stage of transformation, and when I meet those father and daughter again, I will crush one of them to death with one hand!

Zhang Hao, what was the reason just now? "

Zhang Hao smiled: "When my father was promoted to Nascent Soul, there was a tribulation thunder. Others said that robbery thunder is God's eye opening, I think it's a joke. People who don't understand anything, in nonsense.

Later, I thought about it for a long time and thought that the water vapor on the seashore was strong, and the aura gathered during the promotion, which had the same effect as thunderclouds in the sky.

Of course, the specifics are still under study. For the time being, I can only tell my seniors with certainty: this is a natural phenomenon.

In addition, because of the tribulation thunder, the aura is more pure, which is also good for practice. I was thinking, will all those who are at the peak of the Golden Core Stage in Qixia Kingdom come to the seaside to advance. "

"Natural phenomenon?" Liu Dingshan repeated.

"Yes, a natural phenomenon!" Zhang Hao confirmed again.

Liu Dingshan thought for a while, and suddenly laughed loudly again: "Okay, what a natural phenomenon! But this matter should not be publicized, as long as we know it ourselves. In the future, someone will come to the beach to advance, but... it must be a trustworthy person!

It's better not to notify those big families and the like. "

In Liu Dingshan's simple words, he revealed his dissatisfaction with the aristocratic family and the like.

Zhang Hao smiled lightly, it was because you were dissatisfied with the aristocratic family that you were attracted by us.

But the people in Dayang Group were all excited. Practice is opened step by step, and once again grasping an advantage, that is something worth celebrating.

Everyone first congratulated Liu Dingshan for his promotion, and the atmosphere on the scene became active. A master in the late stage of transforming gods is a real life-saving straw for the current Qixia country. The significance is very significant.

But soon everyone fell into the discussion of the pressure, the sky and the earth. After all, the Kingdom of Jinyang has three, maybe four stages of transformation into gods, and there is also a great elder of the Nine Suns Sect who is also recovering. Therefore, the Heaven-Sealing and Land-Sealing Formation is still necessary.

Moreover, the Great Formation of Sealing Heaven and Earth can deal with both the Transformation God stage and the Nascent Soul stage, which is the legion. If you can cover the enemy's checkpoints, camps, etc., you will be excited just thinking about it.
