The people behind were swept away by this sight, and they all quieted down, and they didn't dare to come out.

Seeing this, she smiled, turned around and continued to walk inside.

Passing through an open door, you will be greeted by a relatively formal laboratory.

There was a large, clumsy machine on the test bench, and the roar came from it.

Between it and the workbench, faintly blue sparks flickered, and from time to time there was a sizzling sound.

It can be seen that although its voltage is not very sufficient, it is not low.

Xu Yan groaned slightly, and then put the wooden board in his hand on the ground, and there was still some distance before the operation was lifted.

So I had to come back again.

"What's wrong?"

Ying Zheng saw her leave for a while and came back, but the roar didn't stop, and he couldn't help but ask with concern.

Seeing her father's concern for her, she smiled lightly: "There are only two planks missing." ”

"Huh? Oh. ”

When Ying Zheng heard that this was the reason, he hurriedly said, "You wait here, and my father will go to the back to help you bring it." ”

"Not necessarily."

Xu Yan stopped, "Little sister is not over there, just let her hand over the plank." ”

"That's right."

Turning his head to look at the little girl who was separated by the eight daughters, Yingzheng couldn't help but be stunned, "Father came to talk to your little sister." ”

"Hmm."

Xu Yan didn't rob her father of the emperor's things to do, and waited here quietly.

Seeing that his father and the little sister not far away made a few gestures, Yin Yan really understood, and hurriedly turned around and took the wooden board from the person who came with him, and handed it over carefully.

Seeing that the little girl could understand the meaning of her drawing so easily, Yingzheng was in a very good mood.

He smiled at her encouragingly, took the wooden board and handed it to Xu Yan and asked, "Is two pieces enough?" Why don't you let them hand over two more pieces? ”

"Just hand over another piece."

Xu Yan was also not polite, "By the way, Father, you are staring at Sister Dian, I am worried that after she wakes up from contemplation, she will ignore the current environment and jump off the plank immediately." ”

This is a common problem of scientific researchers, and if you don't pay attention to it, it will go wrong.

Eating ink is considered light, and it would be a bit troublesome to accidentally get injured by electricity like now.

"In addition, if the eighth sister really can't control and get off the plank, don't help her directly with your hands, it's best to clamp her up with the plank."

"Okay, my father has written it down."

Ying Zheng agreed, and then instructed the little girl to bring a wooden plank over, and said to Xu Yan, "You can rest assured to deal with things, my father is here here." ”

Xu Yan looked at the contemplative eighth sister again, bowed to her father, and then turned around and entered the spacious laboratory again.

Seeing this, Yin Yan blinked, hesitated, and turned to ask for a wooden plank.

She didn't bother to pay attention to what was behind her, and at this moment she came back to the console, carefully observing the clumsy bump in front of her, trying to find its power switch.

After looking at it for a while, she couldn't find what she was looking for, so she had to find another path and find a source of power.

Heh, steam generators.

It seems that the only way to do this is to cut off the source of the vapor.

So she searched several more times, and finally opened something that looked like a door, and saw the coals burning inside.

She sighed softly, turned her head to search, and found something that was still usable, a dustpan for garbage.

Then he went back to the big pimple and pulled out the charcoal inside.

Because there was a lot of charcoal in it, it took several times to finish it.

If Zhen Yan hadn't brought her in, the generator would have to stop until the charcoal was burned out, or the steam pump ran out of water.

However, if the water is boiled dry first, there is a high risk of an air pressure explosion.
