good friend?Boy friend!

"Xingbu, even if you are not afraid of Grandpa Xiaoyao, what about the people from the selfish planet and the violent planet? Once they discover our advanced equipment, what will they do if they want to attack us?" Xing Ning expressed concern.

Xing Bu said: "Xing Ning, do you think that we Xiaoyao Planet people can only be slaughtered by others? Let me tell you, I invented this water purification instrument to purify the river water in the park. This is used as a bait to attract people from the planet that opposes our Happy Planet, I would like to see how sacred they are, if I figure it out, I have made a contribution to our Happy Planet."

Xing Bu proudly told Xing Ning about his "majestic talent and great strategy". Instead of applauding him, Xing Ning was frightened instead. How could Xing Bu think this way?No, this is too dangerous, if you are not careful, you will lose everything, she wanted to tell the old man Xiaoyao what Xingbu thought, and Xingbu also guessed that she would think so, he said: "Xing Ning, if you If you want to tell Grandpa Xiaoyao, just tell Grandpa Xiaoyao, it’s better to let him put me in electronic confinement again, just for ten or eight years.”

Xing Ning hopped her feet anxiously, why didn't Xingbu understand what people meant?She told Grandpa Xiaoyao that it was for the good of the whole planet, how could Xingbu not understand?Why is he so focused on doing meritorious service?

Xing Ning persuaded Xingbu again: "Put away your invention. Once something happens, the consequences will be unimaginable. I don't want anything to happen to you, let alone our planet."

Xingbu said confidently: "Don't worry, what can happen? People on the selfish planet are not worth being afraid of."

The more Xing Ning thought about it, the more worried she became. Even if Xing Bu blamed her, she had to tell Old Man Xiaoyao about it.

"Xingbu, take your river water purifier back, it's not a good thing if it's been on the earth for too long." Xing Ning persuaded Xingbu again.

Xingbu became impatient: "Why are you so wordy, you don't need to take care of this matter, I have my own sense of what to do."

Xingbu refused to listen, and Xingning was in a hurry, but there was nothing she could do. She couldn't bear to see that there was something wrong with Happy Planet, and she couldn't take away the river water purifier in front of Xingbu, so she could only "compromise" temporarily: "Okay Xingbu , I don’t care about you anymore, maybe your idea is right, but I didn’t figure it out.”

Xingbu said: "It would be great if you are willing to admit that you didn't figure it out. As I said, I don't do things I'm not sure about."

Xing Ning said: "Then let's go back to the planet, it's getting late, there are still many things to do tomorrow."

Xingbu thought about it, and there are indeed many things to do tomorrow, and he will come to the park to test his achievements at dawn tomorrow morning.

This night, sleep soundly all night.

When Xingbu was preparing to go to the earth the next morning, he received a call from the old man Xiaoyao. He came to the laboratory of the old man Xiaoyao. When he saw the calm face of the old man Xiaoyao, he knew that something was wrong. The old man Xiaoyao already knew, if this is the case, then Xing Ning is the informer.

Sure enough, as Xingbu expected, the river water purifier has been taken to Xiaoyao Planet, and the old man Xiaoyao put him on the experimental table, and said to Xingbu: "Look at this."

Needless to say, the old man Xiaoyao showed Xingbu the river water purifier he invented. It was in the hands of the old man Xiaoyao. Xingbu was not surprised. You shouldn't have told her anything."

The old man Xiaoyao said: "Xingbu, don't blame Xingning, Xingning did nothing wrong, it's just you, Xingbu, why didn't you listen to grandpa?"

Xingbu said: "Grandpa, I don't have one. I invented the river water purifier to purify the lake water in the park. The lake water in the park is very dirty. I just want to make it clean."

The old man Xiaoyao turned on the electronic screen with the remote control, and the lake in the park appeared on the screen. The water in the lake was much clearer than yesterday. Many tourists gathered around the lake, both happy and amazed. They did not understand why the lake water It will become clean, Xingbu thought proudly: Of course it is because of me, the river water purifier I invented made the river water so clean.

The old man Xiaoyao said: "Do you really think so?"

Xingbu said: "Yes, Grandpa, I really think so."

The old man Xiaoyao asked again: "You really just think so?"

Xingbu is very smart, he understood why the old man Xiaoyao asked this question, he secretly blamed Xing Ning, how much did she say to Grandpa Xiaoyao?

Xingbu didn't know how to answer for a while, so the old man Xiaoyao said: "I heard from Xingning that you invented the purifier, and the purpose of purifying the lake is only one aspect. You also want to recruit volunteers, don't you?"

Unable to hide the truth from the old man Xiaoyao, Xingbu admitted frankly: "Yes, Grandpa Xiaoyao, I think this way we can find out whether the people who are unfavorable to us come from the selfish planet or the violent planet."

The old man Xiaoyao said: "Then do you have any detailed plans?"

Xingbu said: "Yes, I installed Xiaoyao Planet's invisible monitoring system on the river water purifier, and connected with my interstellar communication watch. Humans on earth cannot see the river water purifier with naked eyes, nor can they detect it. But once life outside the earth approaches it, it will emit a detection wave, the detection wave will be sensed by the interstellar communication watch, and the monitoring will also be activated. At that time, we will be able to detect who is not good for us."

The old man Xiaoyao said: "So? So this is your plan?"

Xingbu said: "Yes, Grandpa Xiaoyao!"

The old man Xiaoyao said: "You are messing around! It is too dangerous for you to do this. The military strength and technological power of the selfish planet cannot be underestimated, so how can it be easily detected by us? If things other than the happy planet are not good for our happy planet If people can be easily detected by us, then what happened in the theater that day will not be a mystery. Assuming that the people who surrounded you that day came from a selfish planet or a violent planet, you should not act rashly. I am just worried that you did not detect it. Who is the person who is hostile to Xiaoyao Planet, but was attacked by the other party, child, do you understand the stakes?"

The old man Xiaoyao knows that Xingbu is very brave and smart, but his cleverness and bravery are not used at the right time, and now is not the time to go his own way.

The old man Xiaoyao criticized Xingbu, but did not punish him, did not shut him down electronically, but confiscated his river water purifier, Xingbu said: "Grandpa Xiaoyao, if the river water in the park does not have a purifier, it will soon be gone." It's become the same as before."

The old man Xiaoyao said: "If you just want to purify the water in the park and maintain the environment of the park, then there is nothing wrong with it. If you want to make other ideas, I advise you not to think about it. This is an extraordinary period, and I can't let it go. It's up to you to do whatever you want, if something happens, no one will be able to bear the responsibility."

Xingbu said, "What about the river water purifier?"

The old man Xiaoyao said, "Do you still want to bring it to Earth?"

Xingbu hesitated, he thought for a while, and said, "Grandpa, I don't just want to contribute to our happy planet, but I also want to help the earth improve its environment, so I invented the river water purifier, hoping that the water on the earth will be clearer." Some."

The old man Xiaoyao pointed to the picture of the lake water in the park on the screen, and said: "Xingbu, your invention has indeed worked, but it is not a long-term solution. You can purify the water in the park, and even other water on the earth, but But it can't stop people from polluting the water, the pollution continues, and the effect of a small river water purifier is negligible."

Xingbu had a problem, the old man Xiaoyao said, that is, the river water purifier can't do much for the water on the earth, so what should we do, and watch the water in the park become dirty again?
