Chapter 690

Xu Xianwang smiled.

"Of course."

"This is my latest sewage purification system, which can treat sewage well..."

As a result, before his words were finished, a scientist laughed and stood up and said sarcastically.

"Scientist Xu, you are so funny. This is a sophisticated scientific research summit. The scientific research achievements displayed by hundreds of scientists on the stage in front are all tall."

"Your little sewage purification system can be brought to the stage to make a fool of yourself."

"Alas, I thought you had much ability. Now it seems that you are no different from those who sell water purifiers in the streets."

After this person said so, many people at the scene doubted Xu Xianwang, became less blind to worship him, and began to look at him with examination eyes.

Of course, there are many iron powder of Xu Xianwang who stand up and accuse him.

"Shut your mouth and don't understand anything. What qualifications do you have to question Xu scientist."

"That is, if you are a cow, why didn't you win the grand prize before."

"Sit down quickly and don't make a fool of yourself here."

On the stage, Xu Xianwang was very generous. He smiled with gentlemanly demeanor and said to the man.

"You said it very well."

"Science needs to be questioned. Only in constant questioning can we constantly seek innovation and change."

"But before you express your views, please read one of my experiments and say it's not too late."

Then he snapped his fingers.

The assistant immediately handed over a transparent glass cup, which contained black and smelly sewage.

This scene was also magnified to the huge LCD screen.

Therefore, thousands of people present can see clearly.

At this time, the host on the field began to introduce.

"This cup of sewage is just scooped up from the polluted river. It is full of various chemical raw materials."

"This is the relevant inspection report. Please have a look."

Soon, a report issued by relevant departments appeared on the big screen. According to the data of all aspects, this glass of water was indeed polluted too seriously.

Next, Xu Xianwang introduced the glass of water into the instrument.

Through which transparent glass pipes, it can be clearly seen that after entering the instrument, the sewage is gradually filtered and the color begins to become clear.

Everyone can see the whole process clearly.

In less than two seconds, it flowed out of the outlet and turned into a glass of clear water.

If I hadn't seen it with my own eyes, I would have thought it was another glass of water!

Then, Xu Xianwang took a drink himself, and then gave the rest of the water to the host.

That's what I said to everyone.

"I know what I said may not be believed."

"Therefore, we will give this cup of water to the quality inspection staff of relevant departments and issue a test report on site."

"Let's use real data to prove the particularity of my sewage purification system."

As soon as his voice fell, the scientist who had questioned him spoke again, Leng hum said.

"In my opinion, your sewage purification system is far from mine."

Later, the scientist also got on the stage, and his assistant also pushed up an instrument.

However, this instrument looks very different from Xu Xianwang's one.

The scientist looked at Xu Xianwang with disdain, then turned around and said proudly to the audience.

"As you all know, with the increasingly bad ecological environment, water resources on our earth are becoming more and more scarce."

"Have you ever thought about what we should do if one day there is only the last drop of water left on the earth?"

"What should our descendants do?"

"Do you watch them die of thirst?"

When they heard his words, they were silent, and some were bowing their heads and meditating.

The students, including Xu Xianwang, also admit this.

Because this is a fact, those engaged in scientific research have to speak with facts.

"Of course not!"

At this point, his volume rose sharply and said loudly.

"Now I can guarantee that in the future, as long as everyone has a raw water system I study, at least they will not die of thirst."

"A thousand words and ten thousand words are not as persuasive as an experiment!"

With a wave, the assistant under the stage came with a tray in both hands.

There was a lump of dark mud on the tray, emitting a thick stench.

According to the identification of relevant on-site testing departments, it can be determined that this was grabbed from the bottom of a polluted river for decades.

Everyone under the stage could smell the stench and covered their noses. The scientist didn't think so. What he wanted was this effect. Then he took the tray and poured the stinking mud into the instrument. Soon, a miracle happened. Through the transparent glass pipe, people can clearly see that the dark sludge is being rapidly decomposed and refined. Soon, a cup of pure water flowed out of the outlet. It took less than a few seconds to transform from a stinking sludge into a glass of clear water. The visual impact is too strong. The audience was shocked. This is much better than Xu Xianwang's previous experiment. The scientist looked at the shocked eyes of the audience, became more and more proud, glanced contemptuously at Xu Xianwang, and smiled. "In the future, the river will dry up, and even the polluted water resources will no longer exist. I dare ask Professor Xu, what else can you do with your experiment?" "hehe, you just can't find a cup of polluted water, hehe." then, he turned and continued. "However, my scientific research achievements are different. My instrument and equipment can not only extract clean water resources from sludge." "including plants, everything containing water can also extract water resources." then his assistant went up to heaven with a bundle of willow branches just broken from the tree and put them into the instrument. The machine began to roar like a crusher. The miracle happened again. Before long, I saw a glass of clear water flowing out! It was boiling under the stage. "God, it's amazing." "it's like magic." "it must be false, I don't believe it." soon, a good man ran to the street outside, broke many branches and leaves from the green trees, and threw them into the instrument with his own hands. After a few seconds, another glass of water flowed out. Now, everyone was completely stupid. The scene, after a short silence, suddenly burst into thunderous applause. Even Baron William rice, sitting on the rostrum, couldn't help looking at the scientist more, and a look of interest flashed on his face. There are already many people on the stage who are scrambling to book the scientist's experimental equipment. "Well, Professor Xu, you lost, what else to say?" Xu Xianwang was not moved at all. It seemed that what he had just seen was just an interesting juggling, and said with a faint smile. "It's really avant-garde." "but don't forget that science pays attention to preciseness. It won't work to simply win the attention of others and attract attention." "we'd better wait for the test results to come out." after that, we stopped talking to the man, turned around and whispered with several assistants nearby, and didn't take the man seriously at all. The man smiled coldly and said proudly. "OK, since you like to pretend, I'll accompany you to the end." "when the test results come out later, I don't think you have the face to stay here!" thousands of spectators were waiting anxiously. After all, for the experiment, the process is important, but the result is more important. If the result is not perfect or fails to pass, everything else is in vain! Under the stage, the flowers shook their heads constantly in the rain. In their eyes, it was difficult to hide their disappointment. The level of these people can only solve the needs of ordinary people's daily life, far from solving the crisis of the elixir garden.
