The tsunami-like response lasted for nearly five minutes before gradually cooling down. During this period, Wang Zhengyu was even unable to control the atmosphere in the field. {wx}

This cannot be blamed on Wang Zhengyu. After all, unlike in the conference room, this large outdoor product launch conference has a delay in any reaction because the crowd is too large. With the heavy haze, people who are too far away from the rostrum or the large screen cannot see Wang Zhengyu's movements clearly. This also makes Wang Zhengyu unable to rely on body language to command the atmosphere on the scene, so he can only passively wait for the enthusiasm of the crowd to gradually cool down.

In fact, he was only allowed to wait for five minutes and rely on the armed police on the scene to desperately maintain order. If the crowd was allowed to cheer, he would have to wait longer. And on Chang'an Avenue next to **, there were even crowds applauding and cheering.

This horrifying atmosphere also made Wang Zhengyu make a quick decision and not talk too much nonsense on the rostrum. Otherwise, if he would continue to applaud and cheer, he would not know how long the product demonstration will last. You should know that the air is not good now. It is painful to think about it.

"I saw everyone's enthusiasm, but to be honest, I didn't expect this occasion today, and I was really not ready to interact with everyone too much! I just think that everything I say is false now. Since everyone is here for our products, I won't say much! I just want everyone to witness a miracle with me, a miracle that will bring the blue sky and white clouds back. Are you ready?"

"Are ready! Alright!"

Although Wang Zhengyu was ready to welcome the shouts from the audience, the sounds of shouts from near to far, like waves like echoes still shocked him.

Fortunately, the crowd is now looking forward to witnessing the haze removal effect of this product with their own eyes, and there is not too much noise. After the shouting, the crowd returned to peace. It also made Wang Zhengyu wait for about a minute before continuing to speak.

"Okay! Since everyone is ready, let's count down three seconds together. Let's use these last three seconds to take a look at Di'anmen Square, which is like a fairyland in the smoke. Perhaps this is our beautiful Di'anmen Square for the last three seconds, being shrouded in these annoying haze! Now, count down three times with me...two...one!"

Just as the numbers reported in the crowd were still continuing, Wang Zhengyu pointed the remote control in his hand at the haze removal artifact that was standing not far away without hesitation, and pressed the button at the same time.

Without the roar of the machine as imagined, or even without any sound at all, the machine started to run. The crowd in front of the scene could only vaguely see Wang Zhengyu raising his hand. The crowd behind was even shouting excitedly, and few people realized that this haze removal artifact had begun to be activated at this time.

However, at this time, all the staff members who were monitoring the backend were already nervous. They had been monitoring Wang Zhengyu's every move and clearly saw Wang Zhengyu pressing the button in his hand. Now it was time to witness whether this product was effective. A group of commands were sent from the backend center to the monitoring points 6 and 7 kilometers away in Di'anmen Square. Thirty-six drone aerial cameras in the sky also began to stand by nervously.

At this time, the audience watching videos on TV or the Internet even saw Wang Zhengyu's actions before the audience. After all, several cameramen on the scene were nervously paying attention to Wang Zhengyu's every move at any time. When Wang Zhengyu raised his hand, the camera pointed at Wang Zhengyu's finger and gave a big close-up.

So just when the crowd at the scene was not clear that Wang Zhengyu had already started the equipment, these audiences were already worried about the effectiveness of this equipment. Now it has been a minute since Wang Zhengyu pressed the button, but the equipment not far from the rostrum still had no reaction at all. It seemed that there was not even a trace of sound when the machine was running.

Is there something wrong?

Just when this question arose in the minds of the audience who were following the press conference at home or in the unit, the people at the scene also felt something was wrong. In fact, after cooperating with Wang Zhengyu to count down, everyone at the scene began to hold their breath and wait for the miracle to happen. There was no longer too much noise in the entire scene.

This is quite not simple. You should know that Di'anmen Square can cover an area of ​​440,000 square meters, which can accommodate a gathering of millions of people. When martial law was complete, at least nearly 800,000 people had gathered in the square. In addition, the crowd gathered on Chang'an Avenue, the scene was definitely more than one million people.

Now everyone is consciously quieting down. You can imagine that spectacular scene. However, this quiet atmosphere gradually faded away with the haze showing no signs of ease. There are buzzing discussions in the crowd.

At this time, Wang Zhengyu's palm was also sweating. He was not afraid of the equipment malfunctioning. In fact, there was a self-test process of about two minutes from starting to formal operation to taking effect. Moreover, the noise during operation of the equipment was extremely low and almost negligible, so it is normal to see any movement.

But he was just standing on the rostrum and was inspired by the momentum of the crowd on the scene. He forgot about this when he announced the trial run and even created a gimmick of three seconds, which was enough to make him upset.

Fortunately, the crowd at the scene gave enough patience to the device. After more than a minute of silence, there was a rumor of discussion, which made him feel much better. But now he is not suitable to say anything more, so he can only wait with the masses for the equipment to start to work.

Unlike the people watching the fun, his heart was counting down the time silently, and there were still thirty seconds left.

At this time, even many reporters in the media seat could no longer sit still and began to stand up and look at the location where the equipment was placed. The noise among the crowd at the scene became louder and louder!

With only ten seconds left, Wang Zhengyu saw that the crowd seemed to have signs of commotion, so he simply shouted: "Ten!"

His voice calmed the scene again, and everyone's attention was once again attracted by the young figure on the stage.

"Nine!" When Wang Zhengyu followed the second number, many people began to react and began to count with Wang Zhengyu's rhythm.

"Eight!" More and more people joined the countdown ranks, and countless people shouted over the entire Di'anmen Square. Even many viewers who watched on computers or TV were excited by the shouts made by the hundreds of thousands of people, and they involuntarily counted down to the video.

"Seven, six, five, four!" As more people shouted with Wang Zhengyu, the huge sound seemed to shake off the haze a lot, and people became more and more excited.

"Three, two...wow!" Before we could count one, it was impossible to count one. Everyone was shocked by the wonders in front of us. Smoke pillars, like black lines, suddenly appeared in front of everyone out of thin air, and the source of the smoke pillar was officially the highly anticipated haze removal equipment.

These smoke columns twisted their bodies and kept running towards the haze removal equipment from all directions. At the same time, the haze in Di'anmen Square began to decrease at a speed visible to the naked eye. At first, everyone felt that their vision might be only more than ten meters, and in a moment, they at least doubled. As the surroundings became clearer and clearer, even the sunlight began to become much more dazzling.

Many people even couldn't wait to take off their masks and stared at the smoke pillars of the sky that looked like dragons. At this moment, there were bursts of surprise gasp everywhere.

Everyone was shocked by the wonders in front of them, and even more by the fresher and clearer air. In less than a minute, the ubiquitous smog in Di'anmen Square just disappeared magically. People raised their heads and could directly see the blue sky and white clouds...

After the shock, the crowd was completely boiling, shouting and cheering came one after another. The effect of purifying the air was really beyond everyone's imagination.

Wang Zhengyu on the stage finally breathed a sigh of relief, and at the same time, Prime Minister Long, who had already climbed the Di'anmen Tower. You should know that when Wang Zhengyu pressed the button and the machine did not respond at all, Prime Minister Long was even more anxious than Wang Zhengyu. After all, he did not know this device so well like Wang Zhengyu.

However, seeing the haze removal effect of this device with one's own eyes also made Premier Long feel relieved. Just looking at the effect of Di'anmen made him happy enough. Even whether the specific effect of this machine can achieve the expected ability to remove haze within a radius of ten kilometers is not so important.

Unlike Wang Zhengyu and Premier Long who breathed a sigh of relief, the entire live broadcast room was already busy! Thirty-six aerial cameras spread all over Di'anmen have been started, and surveillance data from various places are constantly being sent to the center for summary. Good news keeps coming, which makes the director very busy.

He has to make a choice in all the video materials. The key is that this is still a live broadcast. If the camera is given to whom or not, he has to make a decision in more than ten seconds. This is really not something that ordinary people do.

At this time, people who were watching live broadcasts on TV or the Internet began to boil! They saw the vision of the device starting through the screen, and also clearly understood the impact of this haze removal machine through the constantly switching pictures on TV. They could even send back images transmitted back through aerial cameras of drones. They saw that the haze was significantly reduced rapidly in places that were not only Di'anmen, but even several kilometers away from Di'anmen. Is there any better news than this?

Many people who are deeply affected by the surrounding air pollution even felt that they were crying! This is indeed an exciting moment. (To be continued, please search for Astronomy, novels are better, updated and faster!
