When Shen Han saw the Song father and daughter walking out of the laboratory, he waved his hand in the air.

A flash of blue light sealed the door.

Now, for the Song father and daughter, it seems that it is more difficult to enter the laboratory than to ascend to the sky.

The door was sealed, Shen Han was relieved.

With another wave of his hand, the system warehouse fell from the sky.

Open the door of the warehouse, take out a protective cover from inside, and cover yourself.

And quickly remove the air inside, forming a vacuum state.

With another wave of his hand, a red light flashed in the system warehouse, which disappeared in an instant.

A cleaning robot is left on the ground.

The robot's body was constantly moving, and its ten fingertips were like sprayers, spraying towards the entire room.

360 degrees, spray without dead angle.

Spray for a full 10 minutes.

drop by drop...

The robot sounded an alarm, and the cleaning data came out.

Shen Han walked into the robot, and he pulled out the report card from the port.

It read in small print - LAB, RESIDUE, ZERO.

Chapter 530 He and his daughter carried a huge vacuum cleaner, almost amused Shen Han

"Good job, you can not only clean up the residual radiation in the laboratory, but also the nuclear waste."

"Still, my good helper."

"How to do?"

"I don't know, how can I thank you."

It was the first time for Shen Han to cooperate with a robot.

He talked to the cold robot for the first time, and expressed his sincere thanks.

This is the first time on New Year's Day.

For the first time, we all came together today.

【Ding!System prompt: Host, you don't have to be polite, we are all prosperous, and all are damaged.Helping you clean the laboratory is also a merit. 】

【Ding!System prompt: The host has the function of cleaning up nuclear waste. In the system warehouse, there is a device similar to a laboratory trash can.It's just that this kind of equipment cannot be used easily.

At present, the whole world wants to force Huaxia to sell this technology.We can't follow suit. 】

……

The system seems to be garbled. What I said at the beginning is quite reliable.

Talking, talking, he didn't seem to know what he said.

"To shut up."

"The encyclopedia in the system, the robot that removes radiation, and the trash can that can remove nuclear waste. These devices are in my warehouse. You don't need to tell me how to use them."

……

At the beginning, Shen Han felt that the system was quite powerful.

Unexpectedly, at the critical point, the code was garbled and loosened.

The system seems to have never made a sound, it died down, and it was silent.

He talked about being lonely and feeling so bored.

Suddenly, a red light flashed before the eyes, and the robot turned into a wisp of blue smoke in the red light and disappeared from sight.

Shen Han knew that the robot had returned to the system warehouse.

dong dong dong...

There was the sound of heavy footsteps in the hallway.

Gu Qiu looked around the clean laboratory, and he put the data in his pocket in his pocket.

He knew that Dean Song and Song Xiaoying were here.

They came with the vacuum cleaner.

With a wave of his hand, the blue light that sealed the doorway disappeared instantly.

at the same time.

The invisible shield also disappeared.

Shen Han calmly wiped the test bench with a rag.

He was pretending that the laboratory was clean, and it was for Dean Song to see.

"Shen Han, you don't need to wipe it. You can't clean it even if you wipe it. This vacuum cleaner is different from the household vacuum cleaner. It is specially designed to clean up the remaining impurities and harmful smells in the laboratory."

Dean Song said out of breath.

He and his daughter carried the huge vacuum cleaner, almost amused Shen Han.

The new products designed now are all as small as possible.

It's not like the vacuum cleaner designed by Dean Song, which is similar to the first computer back then, too huge.

...... 0

sizzle...

The vacuum cleaner made weird noises and shuttled through the experiment.

Shen Han looked at that although the vacuum cleaner was very bulky, it was not so flexible when turning around.

but.

There is no suction power. A data appeared in front of his eyes, and the suction power reached a speed of tens of thousands of kilometers per second.

Suction and wind cannot be simply compared.

It's the speed of light.

In less than 10 minutes, the vacuum cleaner sounded an alarm, telling its owner to complete the task.

Dean Song heard the alarm that the vacuum cleaner had completed the task, and he walked into the vacuum cleaner, feeling puzzled.

The number that appears for the vacuum cleaner is zero.

Zero vacuuming, zero nuclear waste going into the vacuum cleaner.

How can it be?

Dean Song exclaimed in his heart.

Chapter 531 Take Da Mimi to Dean Song's house at night, Song Xiaoying will play that one

He couldn't say these things out, if he did, it would be ridiculous.

This vacuum cleaner still wants to apply for a patent, and wants to show it to the world together with the technology of removing nuclear waste.

It's a good thing I didn't say it, if I said it eagerly like a young man, it would show such a face and eyes.

Shen Han had an insight into Dean Song's heart, and he later regretted that he was the first to make it to Dean Song's heart.

but.

He can't say that the laboratory has been cleaned up, and at the same time, there are equipment for decomposing nuclear waste.

That device seems to be more advanced than the patent developed by Dean Song.

For a while, the laboratory was silent.

There was only Dean Song's panting.

Now if a needle falls on the ground, you can hear it.

"The suction of the vacuum cleaner is so strong that it seems to have sucked away the smell of the laboratory."

"Also, I just extract the concentrate, it doesn't seem to be that toxic."

"Just now the trash can was working. In an instant, the exploded alcohol lamp and my protective clothing were all smashed, and then these wastes disappeared."

……

Shen Han intentionally lures it to the trash can, even if he is beaten to death, he can't tell about the robot.

He knew that it was a robot that sucked away the poisonous gas in the laboratory.

Then, through the filter screen, it is purified into air that is beneficial to people to breathe.

"Oh."

"I understand."

Dean Song can only say this, he has to research, research, what's wrong with this vacuum cleaner?

He looked up and saw the wall clock hanging on the wall of the laboratory, and said in a low voice, "Let's withdraw, let the vacuum cleaner work for a while."

"At noon, let's have a light meal in the school cafeteria?"

"Thank you, Dean."

"I really want to have lunch in the school cafeteria. I haven't eaten in the school cafeteria for a long time."

"I really miss it."

"Just, not today."

"The third uncle said just now that after he finds the second uncle, he will make a video call with me and toast to celebrate."

Just as Shen Han was about to say third uncle, he immediately changed it.

He felt that he was brought into the ditch by He Sanzhang, how could an elder brother let his younger brother's child call him uncle.

He looked at Dean Song with some embarrassment, and couldn't have dinner with his old man.

"Look at me, I was so happy that I forgot everything, I just heard what I said to you in the three chapters just now 0..."

"In the evening, if you are free, bring your lover to your house as a guest."

"Come on, identify the door."

"Secondly, let the little girl meet with the respected wife."

"Three times, it can be regarded as practice for the little girl."

"I don't know, can you come to my house?"

……

Shen Han thought about it, and took Da Mimi to Dean Song's house, Song Xiaoying would restrain herself a bit.

Suddenly, feeling inappropriate, Song Xiaoying drove a luxury car and parked at the door of Villa No. [-]. She was so flamboyant and arrogant.

He didn't take Da Mimi seriously at all.

He didn't know, if he took Da Mimi to Dean Song's house at night, which one would Song Xiaoying play?

"Let me see, I've been a little busy recently."
