Ye Wangchuan did not expect Ji Qing to leave such a thing behind. He frowned but did not say anything.
Qiao Nian opened a video file. To her surprise, she realized that not only was there a missile interception system, but there was also the core technology of semiconductors!
Moreover, Ji Qing's semiconductor core technology was at a more advanced level than the present one in the world.
No one had broken through the technology from 20 years ago. No one could even touch the threshold. One could imagine how awesome Ji Qing was back then.
These were all scientific calculations of the highest level. Even she could not understand the mysteries hidden in them at a glance.
Qiao Nian closed the folder and unplugged the USB flash drive. Then, she lowered her eyes and said, "I still need some time to find out what she was researching."
