"Drink the soup first. Gu San made it for you." Ye Wangchuan cooled the chicken soup and handed it over. His handsome face was calm as he said, "I don't recognize the box in your hand, but I know what it's made of. It's made of high-molecular polyethylene, which is usually used in spacecraft or explosion-proof shields."
Qiao Nian took the bowl with one hand, feeling uneasy. In addition, she was holding Ji Qing's box in her left hand, which made it even more inconvenient for her to take the bowl of chicken soup.
She slightly clenched her hand around the box, her lowered eyes were obviously a little heavy, and she looked like she was thinking about something.
"Did this kind of material exist 20 years ago?" Qiao Nian raised his head and asked him.
Ye Wangchuan is in charge of the Ninth Institute. He has been in control of the rare earth trading business in Beijing for a long time and is very familiar with these rare materials.
Seeing that the girl seemed to care a lot about the box, he knew that the box Qiao Nian was playing with might be the 'thing' she risked her life to bring out from Ji's house.
Ye Wangchuan didn't want to answer her for a moment, but his deep eyes met the girl's urgent gaze. He honestly put the chicken soup back on the bedside table and said softly, "20 years ago... it was difficult! This is a high-tech material. 20 years ago, human development in the field of aviation was not as advanced as it is now. These polymer materials are super protective materials that require high-tech additions. With the level of technology 20 years ago, this technology may have existed, but this technology must have been in the hands of only a few people."
"For example, some cutting-edge geniuses from the First Research Institute." Ye Wangchuan looked at her deeply and slowly uttered a conclusion.
Qiao Nian was silent for a moment, then continued to play with the box in his hand with his head down.
She knew that Ji Qing was not an ordinary person, otherwise why would Xie Tingyun, who was known as a master of weapons manufacturing, hold her hand and mention Ji Qing's name to her again and again.
How could Feng Yu have spent 20 years trying to find out the cause of Ji Qing's death
But Qiao Nian didn’t expect that Ji Qing was even more... talented than she imagined!
She turned over the box in her hand. The contrast between her cold white hands and the color of the box was sharp. Qiao Nian looked absent-minded, as if she was thinking about something wholeheartedly.
Seeing that she was lost in thought, Ye Wangchuan was not in a hurry. He simply pulled a chair and sat in front of her bed, then picked up an apple and peeled it for her.
"Master Yu recently published a scientific research result, polyimide-nanomica composite film, which is also a polymer nanomaterial like this one."
"This material has one common feature - it cannot be opened by force."
Ye Wangchuan quickly peeled the apple, cut it into small pieces and put them on a plate for her. He then wiped his hands with a piece of paper, raised his eyelids, and said lazily and casually, "Nian Nian, have you figured out how to open it?"
After hearing what he said, Qiao Nian turned the box over to show him the front, and said expressionlessly, "It has a key. But this lock is as hard to open as the material you mentioned. It's a Luban mechanism lock! Unless you have the key that comes with it, there's 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 a mechanism lock.
But since Qiao Nian said it was a mechanical lock, it must be the legendary Luban mechanical lock that has been lost. He rubbed his brows, feeling a little headache, and looked at the girl: "Then what are you going to do?"
Qiao Nian raised the corner of his mouth, lowered his eyes, his raven-black eyelashes were long and thick, and he said nonchalantly: "...I think I have the key to it."
