Love of a wealthy family: The president seldom shows off his affection

At this time, the fire at the source seemed to be matching the man's words. Not long after the man finished speaking, there was another loud noise from the source of the fire.

bump!
Another explosion!

However, this time the explosion was much smaller than the previous two, but Shen Mingkai and the others were very close to the fire source. The moment they heard the loud noise, they were immediately shaken and had a splitting headache. Their ears were buzzing, and they also clearly felt an invisible and powerful thrust coming towards them, but that thrust was not enough to push them.

And with that loud noise, the fire not far from them instantly increased again.

The thrust was not very strong, Shen Mingkai calmed down for a while and then he recovered, so he looked in the direction of the fire source, and at this moment, the firefighter who was the leader of the team rang again in Shen Mingkai's ears the sound of.

"When we sprayed water just now, there was an explosion like this, but that explosion was much bigger than this one, and the thrust caused by the explosion directly lifted us here, which made us all hurt..."

However, Shen Mingkai ignored the firefighter and kept staring at the blazing fire, because at the source of the fire, Shen Mingkai saw the appearance of a house in a trance, so Shen Mingkai walked slowly towards the source of the fire... …

"Master Shen!"

"Shen Shao..."

The firefighters behind Shen Mingkai saw Shen Mingkai walking towards the source of the fire, they didn't know what Shen Mingkai was going to do, and they didn't know why Shen Mingkai walked towards the source of the fire, so they called out to Shen Mingkai worriedly.

However, Shen Mingkai raised his right hand and gave them a silent gesture, indicating that they don't need to worry, and then walked towards the fire source alone.

Shen Mingkai stopped when he was about three meters away from the fire. He watched carefully the fire that was making clanking noises from time to time. Finally, Shen Mingkai locked his eyes on the source of the fire.

The buzzing sound from the fire at the source is the most frequent, and the most peculiar thing is that the fire light from the fire at the source turned out to be a light blue flame, which is completely different from ordinary flames, and this also made Shen Mingkai Reminiscent of what the firefighters just said, the first explosion was because the firefighters sprayed a large amount of water on the burning trees. Logically speaking, the trees should not ignite again, but the fact is that the trees ignited again, and the fire was even more presumptuous than the previous one, and even drove the fire of the entire forest to burn crazily together.

Thinking of this, Shen Mingkai moved his eyes away from the source of the fire, and he slowly looked towards the sky, and at this moment, he saw the surrounding big trees that were not on fire, their branches in the sky were all They shook violently together, and they all tilted in one direction in unison.

"East!"

As Shen Mingkai said, he looked towards the direction where the fire was spreading, and sure enough, the fire was spreading towards the east.

So Shen Mingkai shifted his gaze to the source of the fire again. He stared at the source of the fire inquiringly, only to see that the burning of the fire at the source of the fire was extremely regular, and it was not so much regular as the burning of the fire. Layered, layered combustion is more common in house construction, is it...

After a long time, Shen Mingkai finally figured it out. To quickly extinguish the forest fire, the method he should use was not the ordinary water spray method, but the foam method.

"Take them, let's go out!"

After he figured it out, Shen Mingkai quickly returned to the firefighters and ordered them.

Although the firefighters didn't know exactly what Shen Mingkai did just now, they all looked excited when they heard Shen Mingkai said that they were going back, so they all followed behind Shen Mingkai, following the traces when they came. go back.

Not long after, Shen Mingkai led the group of firefighters back to the surrounding area of ​​the forest fire. Although the previous small group of firefighters didn't say anything, they were indeed seriously injured, otherwise they wouldn't have been killed. Trapped in the mountains for so long and could not get out.

Seeing Shen Mingkai coming out of the forest, everyone around the forest was very happy, including the group of reporters who also cast admiring and admiring glances, and the happiest person here was the director, who was able to see that Shen Mingkai was safe and sound. Come out, he is the most reassuring person. Fortunately, Shen Mingkai is fine, otherwise, how can he explain to everyone in Star City? The most eye-catching person in Star City was injured in the most protected green forest reserve in Star City. It's really hard to explain.

"Young Master Shen, you're back!" The director rushed over to greet him.

"Director, the current method of extinguishing the fire doesn't work, use the foam method instead!" Shen Mingkai immediately said to the director when he saw the director, but his tone didn't sound like "telling" at all, but more like "Order".

"Okay!" Hearing the tone of Shen Mingkai's order, the director didn't feel that there was anything wrong, so he agreed very sincerely.

I saw the director turn around, with a serious face, and waved at the commander, and the commander was standing by as if he was on standby at any time. As soon as he saw the director beckoning, he quickly ran to the director's side, a little flattering Said: "Director!"

"Go! Tell your subordinates to immediately switch to foam to extinguish the fire. Ordinary fire extinguishing methods won't work at all!" The director ordered to the commander with some reprimands, and his tone was full of contempt and disdain.

"Okay, okay..." the commander said repeatedly, and then ran out as fast as he could to order his firefighters to change the way they put out the fire.

"You guys, don't put out the fire with water here, hurry up and get the pipe full of foam, and use foam to put out the fire, hurry up!" The commander ordered the firefighters.

"Go! Go..."

Shen Mingkai and the director looked at the group of firefighters quietly, with serious and expectant expressions, especially Shen Mingkai, who looked serious and confident, but the director was muttering, Shen Mingkai has gone What exactly was found in the forest, and why did he say that this method of extinguishing the fire was wrong when he came back, and instead used the foam method of extinguishing the fire? Finally, the director couldn't help but speak.

"Young Master Shen! What did you see when you went deep into the forest?" The chief asked cautiously, because he saw that Shen Mingkai's eyebrows frowned slightly when he asked Shen Mingkai.

"Go, find a team of people, and follow the trail we went to the depths of the forest to put out the fire with foam." Shen Mingkai did not answer the director's question, but "ordered" the director to do things again.

"Okay!" Although the director was a little annoyed when he heard Shen Mingkai's order this time, he didn't want to go against Shen Mingkai's intentions, and saw that the director followed Shen Mingkai's wishes again.

After a while, the director came to Shen Mingkai's side after giving instructions to the commander.

But this time, Shen Mingkai took the initiative to explain why he asked the director to use foam fire fighting method.

"Because there are gas reagents deep in the forest!"

"What?" After hearing Shen Mingkai's words, the director was shocked by what Shen Mingkai said, gas reagent!How could that kind of thing appear in the depths of the forest.

"The source of the fire was a house made of trees, and the flames of the things inside were light blue when burned, and hydrogen was the only thing that showed a light blue flame when it burned with oxygen, so I concluded that it provided the source of the fire. What keeps burning is the hydrogen coming from the little tree house."

"Hydrogen..." The director immediately felt reasonable when he heard Shen Mingkai's analysis, but he had a lot of doubts, so he only heard the director ask suspiciously: "If hydrogen and oxygen are combusted, why did only three explosions occur?" , instead of exploding all the time?"

After Shen Mingkai heard the director's question, he glanced at the director indifferently and said: "Only the combustion of impure hydrogen and oxygen can cause an explosion, and there is an explosion limit between these two gases. Between 4% and 75.6%, the two gases will explode when they encounter high temperature."

"Ah!" Hearing Shen Mingkai's explanation, the bureau chief sighed and nodded understandingly, "However, the hydrogen gas in the small tree house deep in the forest has spread and dissipated after such a long period of time. Its concentration should be very low, why is the concentration of hydrogen so coincidentally maintained between the explosion limit and caused the explosion? Moreover, it spread to the outskirts of the forest?"

Hearing the director's question, Shen Mingkai turned his eyes away from the director, turned to the forest fire, and then said to the director: "When the water they spray touches the burning trees, it reduces the contact between the trees and the oxygen. , so that in the reaction between hydrogen and oxygen, the concentration of oxygen decreases, and the concentration of hydrogen increases on the contrary, which makes the concentration of hydrogen increase to within the concentration specified by the explosion limit, causing an explosion, which is why entering the mountain forest The team of firefighters in the center not only failed to put out the fire with water, but also caused an explosion in the forest, which made the fire burn more vigorously. The reason why the hydrogen reached the periphery was because of the wind."

"Wind?!" The director was even more puzzled, "How could the wind make the hydrogen reach the outskirts of the forest?"

"Hydrogen has the lightest density and is the easiest to be blown by the wind. Today, it is windy, and it is due easterly. Wherever the fire spreads, hydrogen is blown in. Therefore, the forest fire spreads due eastward. That's why it didn't start a fire in the entire forest."

"So that's how it is!" The director lowered his head and said silently, then he raised his head again and looked at Shen Mingkai with some admiration, "So Young Master Shen reminded us to use foam fire fighting method..."

At this time, Lin Xinning unexpectedly appeared around the small tree house in the forest...
