This is a 'field of knowledge' that no one has ever heard of. What atmospheric pressure, Reiki pressure, etc., coupled with a series of calculation methods such as 'Reiki Flow', made everyone even more confused.

Huang Mingshan looked at Zhang Hao, and Zhang Hao nodded slightly. Huang Mingshan immediately said to everyone: "Let's do a test, and explain the situation through the test." ”

"First of all we say stones. Now let's put a stone on the ground, is there any pressure underneath the stone?"

Everyone nodded.

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

Huang Mingshan's stones were superimposed, and everyone suddenly realized. Huang Mingshan proposed the concept of pressure: "The ratio of the pressure above to the pressure area is called pressure. In the case of a stone in front of you, for example, the pressure is related to the weight of the stone above and the area of force below.

Let's talk about water, and if we take a piece of water alone, is it similar to this stone? except that the stone is replaced by water, and the ground is replaced by the bottom of the lake. ”

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

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

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

Huang Mingshan has one hemisphere in one hand, opening and closing, and 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 closed hemispheres were put into the lake, but they did not separate after entering the water, and they quickly sank to the bottom and fell into a patch of aquatic weeds, startling a small fry.

Huang Mingshan made an inviting gesture: "Please seniors open these two hemispheres from the bottom of the water." Hold the handles at both ends with both hands and see how much force is needed.

As I explained in advance, I couldn't open the ball at a depth of two meters. And now it's about five or six meters deep. ”

Liu Dingshan didn't ask, he didn't hesitate to drill into the lake water, and held the two ends of the steel ball under the lake water, but he didn't pull it away the first time. A little afterburner, but it still didn't pull away. In the end, it took a lot of force to pull the hemisphere apart.

But listen to the thud below the lake, a little turbulence appears, and a little silt is rolled up at the bottom of the lake.

Liu Dingshan surfaced, he didn't speak, just observed the two hemispheres separately, then closed them again, and then entered the water and pulled away. After doing this several times, Liu Dingshan thought thoughtfully: "This is ...... Water pressure?"

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

Liu Dingshan tried it a few more times, and the rest of the masters dived one after another to do the experiment. In the end, everyone was a little surprised. It's really simple to debunk, but it's still amazing.

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

There are two. One is 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 float in the air, like those suspended aquatic plants in the water."

And the second is Reiki. The source of the aura that we practice in our daily life is all around us.

Now, I close the two hemispheres together and pull the air out of them. Senior Liu, can I trouble you again, through this air extraction, use a spell similar to a dragon to absorb water, and drain the air from it. ”

Liu Dingshan had long been impressed by this new knowledge, and 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, please open these two hemispheres seniors." ”

Liu Dingshan used both hands hard, and he couldn't open it the first time. It wasn't until faint green tendons appeared in both arms that he finally pulled the steel ball away. There was a loud 'Boer' sound in the air.

Liu Dingshan repeated it a few more times, thoughtfully: "This pressure is even greater than the pressure under the water just now." I estimated that if I only calculated the strength of the flesh and blood, I needed the strength of the late stage of Jindan to pull this steel ball away. Is this atmospheric pressure?"

Huang Mingshan nodded, "Yes, this is atmospheric pressure." According to our tests, atmospheric pressure, to be exact, is equivalent to the pressure at a depth of 15 meters.

So it is with the air, and so is the aura. It's just that we haven't calculated the pressure of the aura yet. But it's not too weak to think about.

Senior, a small steel ball is under such pressure, so if this steel ball increases to ten meters, one hundred meters, and one thousand meters in diameter, how much pressure will it bear?"

Liu Dingshan's complexion changed a little. He was silent for a while, and then said leisurely: "Sure enough, there is an end to manpower." World...... is the greatest. ”

But 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 the transformation of the gods." Haha......"

The roar is like the roar of the waves, the clouds above the sky have collapsed, and the sky is as blue as a wash. The laughter was still spreading, Liu Dingshan's momentum was rising, and the heavy pressure made Zhang Hao feel that it was extremely difficult to breathe.

The surrounding aura gathers, and then ...... Yes, compared to the breakthrough of the Yuan Infant Stage, it is not the gathering of aura at all at the moment, but the collapse of the aura of the entire heaven and earth.

Zhang Hao even saw that the aura around Liu Dingshan fluctuated like water ripples, and this aura was almost like substance.

Suddenly, a white rainbow appeared from the top of Liu Dingshan's head, penetrating the sky. The spiritual energy in the sky swirled, and whirlpools gradually appeared, and rainbow lights appeared all around.

But almost at the same time, lightning also appeared! Tiny lightning bolts, like naughty little snakes, shuttled in the whirlpool. But soon the little snake turned into a poisonous snake, crazy and hideous.

Liu Dingshan's face changed greatly: "Lying grass, how can there be a thunderstorm!"

Zhang Hao was relatively calm, and the only thing that shocked him was Liu Dingshan's breakthrough. Zhang Hao immediately asked people to build iron pillars and iron shelves, and iron cables were connected to them. Iron cables, iron shelves, etc., are all buried in the ground, and even brought into the artificial lake next to it.

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

The aura vortex in the sky was like an ocean tide, and the center began to fall, falling along the white rainbow above Liu Dingshan's head. At the same time, a large number of lightning bolts were flickering wildly.

Finally, a bolt of lightning fell down the white rainbow, but soon fell on the iron cable, and the crazy thunder and lightning smashed down the iron cable into the ground and the lake. Dirt splashes and water splashes.

Then there was a crisp bang between the heavens and the earth, as if the sky was torn apart. The crisp sound makes my heart tremble.

But that's just the beginning.

The aura vortex finally landed on the top of Liu Dingshan's head, and the crazy lightning was actually taken away by iron pillars, iron shelves, iron cables, etc.

Everyone was amazed, the gap between the iron cables was obviously very large, but the lightning actually turned a bend and slashed down the iron cables, ignoring Liu Dingshan below.

The vision came and went quickly, after all, it was only a small breakthrough, not a promotion.

Liu Dingshan was suspended in mid-air, full of momentum, and Zhang Hao faintly felt that he couldn't get close. And Liu Dingshan is observing those iron cables. There are already a lot of iron cables that have melted.

Liu Dingshan's eyes were full of curiosity and surprise. I found out that I had caused a thunderstorm, and I was a little flustered in my heart - I didn't do anything hurtful. Then he was stunned by Zhang Hao's methods.

It took Liu Dingshan a while to gradually rein in the momentum on his body, and a bright smile appeared on his face. "It's the late stage of the god, then Zhao Kai is in the middle stage of the god, Zhao Ying is only in the early stage of the god, and when I meet that father and daughter again, I will pinch one to death with one hand!

Zhang Hao, what was the reason just now?"

Zhang Hao smiled: "When my father was promoted to Yuanying, there was a thunderstorm. Others say that the thunder robbery is something that is an eye-opener or something, and I think that's a joke. People who don't understand anything, are talking nonsense.

Later, I thought about it for a long time and thought that the water vapor on the seaside was strong, and when I was promoted, the aura converged, and the effect was like a thundercloud in the sky.

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

In addition, because of the thunderstorm, the aura is more pure, and it is also good for cultivation. I'm wondering if all those who are at the peak of the Jindan period in the country of Qixia will come to the beach to advance in the future. ”

"Natural phenomenon?" Liu Dingshan repeated.

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

Liu Dingshan thought for a while, and suddenly laughed out loud again: "Okay, what a natural phenomenon! But this matter should not be publicized, we just know it ourselves." In the future, someone will come to the beach to advance, but ...... Must be someone to believe in!

Those who are from a big family or something, don't tell me. ”

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

Zhang Hao smiled faintly, it is because you are dissatisfied with the family that you can be won over by us.

And the people of Dayang Group were excited. The practice is all started step by step, and it is a thing to celebrate when you once again have an advantage.

Everyone congratulated Liu Dingshan on his promotion, and the atmosphere began to liven up. A master in the late stage of the transformation of the god is a real lifesaver for the current country of Qixia. The significance is significant.

But soon everyone fell back into the discussion of the pressure and the sealing of the world. After all, there are three and possibly four god transformation stages in the country of Jinyang, and there is also a great elder of the Jiuyang Sect who is also recovering. Therefore, the Great Array of Heaven and Earth Sealing is still required.

Moreover, the Heaven and Earth Sealing Array can deal with the Transformation God Period, and it can also deal with the Yuan Infant Stage and the Legion. If you can envelop the enemy's checkpoints, camps, etc., it will make you excited to think about it.
