good friend?Boy friend!

"Xingbu, let's go, let's pick up the trash, I also think we shouldn't litter, if everyone does this, our park will become a dump."

Hua Jinyun took Xingbu to the place where the man threw the garbage just now, picked up the garbage he threw, and threw the garbage into the trash can. He found the garbage thrown by other people, picked it up and threw it into the trash can, Xing Together with him, Bubu also picked up a lot of rubbish. Even so, the rubbish in the park is still everywhere.

The two came to the lake, the lotus leaves lined up in the lake, dancing gracefully under the breeze, the fly in the ointment was that there was a plastic bag floating beside the lotus leaves, which ruined the beauty of the whole, and it was still the same when they went elsewhere. Xingbu asked Hua Jinyun why the lake water was so dirty. Hua Jinyun said: "A few years ago, the environment in the park was very good and the lake water was clear. In recent years, the population of Chaojiang City has increased, and more people come to the park to play. With more people, there will be more garbage, the environment will inevitably be polluted, and the scenery of the park will not be as good as before."

Xingbu thought, this is not going to work. If the pollution continues like this, the water in the park will soon become a puddle of dirty water, a puddle of rotten water. .It is impossible to rely on the earthlings themselves, but to rely on him, a little inventor on the happy planet.

"The solution to the problem still depends on high technology." Xingbu said to himself, he looked at the lake water, and wanted to collect samples of the lake water to study on Xiaoyao Planet, "Near Yun, I want to find an empty mineral water bottle."

Hua Jinyun said, "What do you want an empty mineral water bottle for?"

Xingbu said: "You will know in a while."

Hua Jinyun said, "Okay, I'll help you find a bottle."

Hua Jinyun went to help Xingbu find an empty mineral water bottle. Xingbu squatted by the river, thinking that after he got the bottle in a while, he would collect some lake water samples. After he returned to Xiaoyao Planet to do some research, there would be a solution way out.

Hua Jinyun didn't find an empty mineral water bottle nearby, so he bought a new bottle of mineral water. After drinking the mineral water with Xingbu, he gave the empty mineral water bottle to Xingbu. Xingbu took the bottle and said: " When I don’t want empty bottles, people throw bottles everywhere, and when I want empty bottles, there are no empty bottles.”

Hua Jinyun said: "It's better not to have empty bottles. If there are no empty bottles, the environment will not be polluted."

Xingbu said: "I also don't want the environment to be polluted, so change is imminent."

Xingbu used the empty mineral water bottle Hua Jinyun gave him to a place where the water was dirty and shallow, and bent down to collect lake water samples, but Hua Jinyun stopped him and said, "Xingbu, what are you doing? It's so dangerous, don't play with the water. "

Xingbu said: "I didn't play in the water, I was doing business."

Hua Jinyun said: "What's the matter, come up quickly, be careful, don't fall into the water."

Xingbu said, "I'm fine. I'll be careful. I'll be fine in a while."

Xingbu quickly collected samples of the lake water. The dirty and degraded lake water dyed the clean and transparent plastic bottle a faint green. Xingbu said, "It really is blue sky and clear water."

Hua Jinyun felt very sad when he saw such water, "Xingbu, the water in the park used to be not this color. In recent years, due to environmental pollution, the water quality has deteriorated a lot compared to before, and the pollution has become more and more serious. , so it became what it is now.”

Xingbu said: "That's why we need to change the water quality."

Hua Jinyun said: "I also want to change the water quality, but I can't do anything."

Xingbu said: "There will be a solution, trust me."

Hua Jinyun said: "Maybe, but our current technology can't solve the problem of water quality deterioration."

Xingbu thought, the earth's technology can't solve it, and it doesn't mean that the planet Xiaoyao can't do it. He brought the water samples back to the planet Xiaoyao to study, and he believed that he would gain something.

Hua Jinyun said, "Xingbu, you haven't told me what you do with dirty water in plastic bottles?"

Xingbu said, "I'll take it back and study it."

Hua Jinyun said: "You take it back and study it? Is it okay?"

Xingbu realized that he had said the wrong thing again, and quickly changed his words: "Yes...I took it back and asked grandpa to study it. Grandpa works in the Academy of Sciences, maybe he will have a way."

Hua Jinyun hoped that Xingbu's grandfather could find a way to improve the water quality, so that the lake in the park would be clearer.

"Xingbu, when you are with grandpa, do you also discuss science with him?"

"Yeah, we often discuss, and I can learn a lot from my grandfather."

"It's no wonder you can master so much scientific knowledge. It turns out that you are with grandpa, and you can see and hear it."

Xingbu tacitly agrees that what Hua Jinyun said is correct, and the most important thing is that he is born with a high IQ and has mastered a lot of scientific knowledge. This is something that people on earth cannot envy.

After Xingbu collected the lake water samples, he wanted to go back to Xiaoyao Planet for research. Hua Jinyun invited him to lunch, but he declined, saying that he would definitely accompany him next time.Without Xingbu's company, Hua Jinyun was lost in an instant, but in the afternoon, Hua's father came back from work, which is really gratifying.

After Xingbu returned to Xiaoyao Planet, he came to his laboratory to test the lake water samples. After the test, he analyzed the test results and soon had a countermeasure.He invented a river water purifier, which can effectively purify sewage, absorb harmful components in sewage, and at the same time crush the garbage in the lake water, making the lake water clear again. With it, not only the water quality of the park can be improved, but those polluted Rivers can also become clean.After inventing the river water purifier, Xingbu was ready to go to the earth. As soon as he left the laboratory, he met Xingning. Xingning saw that he was holding a small blue fluorescent ball in his hand. He was curious about what it was and wanted to Take it for a look, but Xingbu refused, "This is my great invention, it will be bad if you break it."

Xing Ning said: "Great invention? How great? Tell me about it?"

Xingbu was the first to tell the truth: "Anyway, it's great, do you want to see it?"

Xing Ning said: "Aren't you going to trick someone again?"

Xingbu said: "When did I punish someone?"

Xing Ning said: "Last time, you did the high-intelligence robot thing, have you forgotten? If you have any crooked ideas, be careful that Grandpa Xiaoyao will find out."

Xing Bu said: "Last time something happened, and I also had some things I didn't think about. This time it won't happen. Xing Ning, I'll take you to Earth to see and see."

Xing Ning was curious for a while, and followed Xingbu to the earth. Although it was night, there were not many people in the park, and there were no less people walking by the lake than yesterday. Xingbu turned on the invisible function of the river water purifier , and then put it into the water, Xing Ning didn't understand, he explained the whole story to her, Xing Ning thought it would be a good thing to purify the river water, but it would be bad if the old man Xiaoyao found out.

"Xingbu, you clearly know that Grandpa Xiaoyao doesn't let us use high-tech. Didn't you make Grandpa angry by doing this? Take it back quickly. If Grandpa Xiaoyao finds out, he should punish you for electronic confinement again." Ningquanxing Trail.

Xing Bu didn't take it seriously, he thought what he did was right, "Xing Ning, do you really think that grandpa will not let us use high technology? We don't use high technology to punish people, it's okay to use high technology to help people, so you Don't worry."

Xing Ning still felt that there was something inappropriate. Grandpa Xiaoyao told them not to use high technology. Naturally, there was a reason for him. They had to listen to Grandpa and not make Grandpa unhappy, but Xingbu didn't listen to her advice, and she couldn't do anything about it. .
