When Yunhua fed back the situation to Luo Yangfeng, it immediately attracted the attention of the little old man.

As Yunhua said, once or twice can also be explained by coincidence, and there must be a reason for eight times and ten times...

As a scientific research worker, Luo Yangfeng's intuition is also very keen, and he feels that this may be a new way of thinking.

And if you dig deeper, you might make a big discovery!

So, Luo Lao led everyone to put down the work at hand, came to the location of the underground runoff, and said to Yunhua: "You let the cradle lily demonstrate again, we have to see it with our own eyes." ”

"Okay!"

Yunhua said hello to Cradle Lily, who immediately took root again.

After three months of growth, Sayuri's strength has also made great progress.

In particular, its "water diversion" characteristics, because it has to penetrate sixty or seventy meters of sand layer every day to absorb water, which is equivalent to special training, so the water control ability has also been greatly improved.

At this time, it activated the "water diversion" effect again, and the water suddenly gushed out of the ground like a fountain.

At the same time, Sayuri's water output efficiency has also improved a lot, and the water flow has changed from one finger thick to three finger thick, comparable to tap water.

Half a minute later, the dunes were moistened with a large area, but nothing changed.

An hour later, the dunes still hadn't collapsed.

But Luo Lao and the researchers didn't speak, just watched all this silently.

As a researcher, patience is an essential ingredient for everyone.

Yunhua was faintly impatient.

In the end, it was Luo Lao who spoke to comfort him: "Don't worry, research experiments rarely succeed at one time, wait patiently!" ”

"Okay!"

Yunhua nodded, his eyes staring at the sand dune area under Sayuri, he only hoped that the scene of the collapse would appear sooner.

I don't know how long it took, when Yunhua's eyes were sour, the scene he had been waiting for for a long time finally appeared again.

Thundered!

With the water point as the center, the sand dunes sink again, forming a whirlpool-like shape, and the quicksand rolls.

Compared with the large area of the quicksand field, the area affected by the collapse of the water outlet point is very small, only a dozen square meters.

But in that area of more than ten square meters, the speed of collapse is very, very fast, almost between lightning and flint, which makes it difficult for people to react.

Not only that, but the depth of the collapse in the central area is also very deep, two or three meters deep, which can completely bury and engulf an elf in an instant.

As for the subsequent collapse diffusion, it is much slower, and the depth of the collapse is much smaller, at most it is just the icing on the cake, which is better than nothing.

"It's really collapsed!"

Luo Yangfeng's eyes lit up, and his face was full of surprise.

When doing scientific research, the most feared thing is that there is no idea and no direction to go.

And Yunhua directly gave him a big gift.

A research idea that is feasible and feasible!

"Water and sand? Percolation? ”

Luo Yangfeng was pleasantly surprised, and he also began to think.

Although he had been experimenting with sand all his life, he had never taken water into account before, as he was known to be very thin in deserts.

Luo Yangfeng doesn't know much about the nature of water.

"Have any of you ever taken hydraulics? Fluid mechanics or micromechanics are fine! ”

Luo Yangfeng set his eyes on the members, all of whom were top students of Jiangnan University, and they also had a role in checking and filling in the gaps for him.

"Luo Lao, I have taken hydraulics!"

Qin Chong looked around and raised his hand in the dark.

Luo Yangfeng was overjoyed when he saw this, and said excitedly: "Can you see the principle of the collapse phenomenon just now?" ”

"I speculate that groundwater should flow upwards due to the 'water diversion' properties of the cradle lily, and that the water can cause the sand to float against gravity in the process of flowing upwards, so that the sand loses its load-bearing capacity. Therefore, when there are elves or other heavy objects standing on top of the sand, the sand cannot withstand the force, it will automatically sink, and eventually form quicksand. ”

Qin Chong scratched his face and said what was in his heart.

"It's kind of interesting!"

Luo Yangfeng stared.

Although Qin Chong is only a master's degree, if he can enter his team, he must be a top student with a solid foundation.

Although Qin Chong used the word "speculation", Luo Yangfeng estimated that the principle was not far from ten, and it must be like this.

However, just in case, Luo Yangfeng still sent two other people out of the desert to contact the masters of hydraulics to verify the authenticity of the theory.

No way, study the hellish place of the station, and you don't expect a signal.

If you want to make a call, you have to run hundreds of kilometers!

After assigning the task, Luo Yangfeng continued to speak: "Let's assume that Xiao Qin's theory just now is correct, then take this as the premise. Let's talk about what direction we are just going to study next! ”

"Luo Lao, I have an idea."

Dr. Zhang Yuanhua was the first to raise his hand, and after receiving the answer, he said: "I think the flow rate of water should be a research breakthrough point. The faster the water seeps in the opposite direction, the faster the dunes may collapse, and the more powerful they will be. ”

"It's a train of thought!"

Luo Yangfeng pushed the frame of his glasses, and hurriedly took a pen and recorded it in his notebook.

After the conversation box was opened, the research team members also made suggestions.

At this time, the role of top scientific research team members is reflected, almost everyone has an idea, and it doesn't take long for Luo Lao to write down a page full of new ideas.

The next task is to test the new ideas one by one.

In this process, Yun Hua, Fang Xiao, Yuan Weiming and the like are completely unable to interject, they can be regarded as the audience in the venue, and the emphasis is on experiencing this sense of joy.

"Okay, let's start with the first one. What can you do to increase the flow rate? ”

The big idea is the reverse seepage, and the small idea is the suggestion put forward by everyone, but in order to put the suggestion into practice, there must be specific and feasible measures.

"The velocity of the water body is controlled by the water diversion characteristics of the elves."

Qin Chong raised his hand again: "Old Luo, why don't we apply for another elf with water diversion characteristics?" The strength is best at the gym level, and the development of water diversion characteristics should not be too bad, at least stronger than Cradle Lily. ”

If you want to increase the flow rate, you have to find a spirit with more powerful water control ability to participate in the experiment.

But the water-attracting properties of the cradle lily are already much stronger than the professional-level sand bell cactus.

Further up, then you can only shake another person.

"Gym level? I'm afraid it will take a lot of time. ”

Luo Yangfeng had helplessness on his face.

Elf, with his status, he can definitely apply for it.

However, there is no way to omit the procedure and the time it takes.

Especially the elves with this special request, don't even think about applying for it in a month.

"Increasing the flow rate of reverse seepage?"

Yun Hua, who had been acting as an audience member in the venue, raised his eyebrows and suddenly had an idea.

So he raised his hand and said, "Old Luo, I have a solution." Maybe you can try it now! ”
