Fake daughters are wealthy

"You drink the soup first, and Gu San stewed it for you." Ye Wangchuan blew the chicken soup over and passed it over, Qingjun's face was very calm, and said: "I don't know the box in your hand, but I know the material of this box. High polymer polyethylene material, this material is generally used in aerospace vehicles or explosion-proof shields."

Qiao Nian was worried about taking the bowl with one hand, and it was even more inconvenient for her to take the bowl of chicken soup with Ji Qing's box in her left hand.

She slightly closed her hand holding the box, her lowered eyes were obviously a little downcast, and she looked thoughtful.

"Did there be such materials 20 years ago?" Qiao Nian raised his head and asked him.

Ye Wangchuan is in charge of the No. [-] Research Institute. He has been in charge of the rare earth trading business in Beijing for a long time, and he is very familiar with these rare materials.

He saw that the girl seemed to be very concerned about this box, and he already knew that the box Qiao Nian was playing with might be the 'thing' she had brought out from Ji's house on an adventure.

Ye Wangchuan didn't want to answer her for a moment, but Shentong met the girl's eager gaze, and he put the chicken soup back on the bedside table temporarily with disobedient honesty, and said gently: "20 years ago...it was difficult! This is a high-tech material. 20 years ago, the development of human beings in the field of aviation was not as developed as it is now. These polymer materials are super protective materials that require high-tech additions. This technology may exist at the level of technology 20 years ago, but this technology must only be mastered In the hands of a few."

"For example, some cutting-edge geniuses in the First Research Institute." Ye Wangchuan looked at her deeply, and slowly spit out a conclusion.

Qiao Nian was silent for a moment, then continued to lower her head and play with the box in her hand.

She knew that Ji Qing was not an ordinary person, otherwise, how could Xie Tingyun, who is known as a master weapon maker, hold her hand and mention Ji Qing's name to her again and again.

How could Feng Yu have been trying to find out the cause of Ji Qing's death for 20 years.

It's just that Qiao Nian didn't expect Ji Qing to be more...genius than she imagined!

She turned over the box in her hand, the contrast between her cold white hand and the color of the box was strong, Qiao Nian seemed to be absent-minded, as if she was thinking about something wholeheartedly.

Seeing her lost in thought, Ye Wangchuan was not in a hurry, he just pulled a chair and sat in front of her hospital bed, picked up an apple and peeled it for her.

"The polyimide-nano-mica composite film, a scientific research achievement announced by Master Yu not long ago, is a polymer nanomaterial just like this one."

"This kind of material has a common feature-it cannot be opened by force."

Ye Wangchuan quickly peeled and cut the apple into small pieces and put them on a plate for her, then took out a piece of paper to wipe his hands, raised his eyelids, and said lazily, "Nian Nian, you Have you figured out how to open it?"

After hearing what he said, Qiao Nian turned over the box in his hand to show him the front, and said expressionlessly: "It has a key. But this kind of lock is as difficult to open as the material you mentioned. It is a Luban mechanism lock! Unless there is It comes with the key, otherwise there is no way to open it."

Ye Wangchuan saw the keyhole on the front of the box at a glance, it looked ordinary, and there was no trace of the mechanism lock.

But since Qiao Nian said it was a mechanism lock, it was [-]% the legendary Luban mechanism lock that had been lost.He rubbed the center of his brows, and looked at the girl with a headache: "Then what are you going to do?"

The corners of Qiao Nian's mouth curled up, his eyes drooped, his crow-black eyelashes were long and thick, and he said casually: "...I seem to have the key to it."
