Jiang Ni didn't deliberately lower her voice when she entered the door, Wei Hongyu, who heard the movement, raised her head, and beckoned her to come down in a deflated manner, complaining: "I've been looking for your dad for hours and haven't found it, I really can't stand it." ”

"Niel, you can try it too, and see if you can find a place to get in and out?" Jiang Ziqiang was also a little discouraged, but he was still a little unconvinced, so he pinned his hopes on Jiang Ni.

Jiang Ni: "......"

She silently began to look around to no avail.

Looking up and seeing her parents' hopeful eyes, she endured it and searched for it again to no avail.

She thought to herself, forget it, is it necessary to be so serious? But seeing the disappointment on her parents' faces, she gritted her teeth and called Fu'er in her consciousness----

"Found it?"

After communicating with Fu'er, Jiang Ni continued to pat and pat around pretending to be looking for it. Finally, as if unintentionally, the hand made a slight noise when it hit a place that looked indistinguishable from the rest of the wall, and a staircase cracked open on the ground that could only accommodate one person going down.

Doing a full set of plays, looking at the exposed entrances and exits, Jiang Ni pretended to be surprised and froze.

“...... It seems that our Nier's luck is extraordinary. Wei Hongyu and Jiang Ziqiang, who had already given up in disappointment, were also full of surprise.

Especially after stepping forward to carefully inspect the wall that Jiang Ni "unintentionally" photographed, but didn't see any difference between it and other places, the two were speechless for a while, and Wei Hongyu could only explain it with luck.

Jiang Ziqiang was still studying the wall, stretched out his hand and patted again, but the entrance and exit of the cellar did not respond. He was a little puzzled: "Shouldn't this shoot be turned off, and then turn it on?" ”

Saying that, he didn't give up on another beat, this time he used more force, and made a sound, and then he saw the entrance and exit huo Ran close.

"So it's not enough energy?"

Jiang Ziqiang muttered to himself, stretched out his hand and slapped it down with a heavy palm, and Jiang Ni and Wei Hongyu, who looked hard, couldn't help but feel pain in his hands.

I don't think I'm going to feel it, so I patted it all the time. I felt that the wall was different from the rest again and again.

But looking at the opening and closing of the entrance and exit of the cellar, he found nothing, and finally helplessly and puzzled: "There is really no difference, what is going on?" ”

Jiang Ni knew what was going on, but she couldn't say, so she called Fu'er out. Fu'er could only patiently explain to Jiang Ziqiang and Wei Hongyu again: "It's very simple, I use gene voice-activated sensing at this entrance. ”

Gene voice-activated sensing?

Jiang Ziqiang and Wei Hongyu glanced at each other, they were all the same, whether they understood or not.

Fu'er explained carefully: "I extracted your genes before, and in the future, as long as the human being who carries your common genes makes a sound near this entrance, the door will naturally open." ”

"You're saying that I can open the entrance and exit here, not because it's any different from other places. But because as long as I get close to this place, there is a noise, and the door can be opened? ”

What genes are not genes in the first half, Jiang Ziqiang and Wei Hongyu still can't understand. But they all understood the second half.

Fu'er nodded, perceiving that the two of them couldn't understand the first half of his words, so he thoughtfully explained again in simpler words: "That's right, as long as it is your blood descendant in the future." As soon as the skin of the body touches the entrance and makes a sound, the door can be opened. ”

"I see."

Jiang Ziqiang and Wei Hongyu were both stunned, and then Jiang Ziqiang asked in his heart: "Since you can make such a door." Can you make a box that opens like this, but is smaller and stronger, and cannot be easily opened by others? ”

He explained: "If we can, then as long as we go out with such a suitcase, wouldn't it be safer to put important things inside?" ”

Isn't that just a portable safe?

Jiang Ni said silently in her heart, she didn't expect her father to be far-sighted and even take this into account. Thinking that this thing was indeed used, she was interested in looking at Fu'er and seeing what it had to say.

"Yes." Fu'er nodded, "What size do you need?" ”

"How small can it be?" Wei Hongyu couldn't help but interject curiously and asked, "How is the weight?" ”

"If you want to make it the size of your little thumb, you can do that."

Fu'er thought for a while and said, "But it is not recommended that you waste materials, because the material reserves of the space are limited. As for the weight, it weighs only a quarter of the same size of a wooden box. ”

"So light? Will it not be able to open but be smashed open in the end? Jiang Ziqiang suddenly felt a little uneasy.

"No, it is invulnerable, not only can it isolate the heat of more than 5,000 degrees, but it can also withstand the heavy blow of more than a million times its own weight."

Fu'er said confidently: "No one can open it except for the owner and the blood descendants of the owner. ”

"And can you put another lock on it, a lock that is just as strong, but only the owner knows how to open it?"

Thinking of using that gene voice activated induction unlocking method, although it sounds lofty, if that unlocking method is accidentally leaked, it will be known. No matter how strong the box is, outsiders may not really be able to open it. Therefore, Jiang Ni thinks that it is more reassuring to have double insurance.

Jiang Ni's concerns are obviously also Jiang Ziqiang and Wei Hongyu's concerns. The two nodded at the same time, and they both looked at Fu'er with hope.

"No problem." Fu'er quickly figured out the scruples of several people, and asked thoughtfully by the way, "Do you need to install another lock for this entrance?" ”

"Mom and Dad, what do you say?" Jiang Ni looked at Jiang Ziqiang and Wei Hongyu.

"That's not necessary, right? I see what kind of gene voice lock is enough here. Jiang Ziqiang shook his head, Wei Hongyu thought about it and felt that there was no need to say, "It's almost fine if the small box has another lock." ”

"Then make two boxes, one larger, about the size of a box for clothes, and put it at home; The other is smaller, the size of a book, almost twice as thick as a book. ”

Jiang Ziqiang quickly made a decision: "In the future, let's go out, whether it's in the basket or in the satchel, we can put it." ”

Wei Hongyu and Jiang Ni had no opinion on his decision.

"Okay. However, due to the lack of complete tools, it will take some time for the small box to be made, and you need to wait patiently. ”

Fu'er was worried that if she didn't give the three of them a preventive shot first, the three of them were afraid that they would mistakenly think that it was particularly easy to make a sealed box, and they would have the illusion that they could get it immediately.
