By installing Personal Terminals for Miyano Akemi and Shiho Miyano, Fang Zheng successfully convinced them of his story. Shiho Miyano in particular, though she had not studied electronics, knew that all cutting-edge scientific research relied on highly advanced technology. After discovering that the tiny device before her, barely the size of a pinky nail, possessed computing power thousands of times greater than the most advanced supercomputers, she had no choice but to accept Fang Zheng's explanation.
After all, whether in terms of craftsmanship or manufacturing technology, this thing was absolutely beyond the level of technology Earth currently possessed.
So either it had popped out of a crack in a rock, or it had been created by a more advanced civilization... The latter was obviously more logical.
The Personal Terminals Fang Zheng gave them were not merely for communication. Miyano Akemi's Personal Terminal possessed a special optical camouflage function that could alter her face and turn her into someone else. After all, Miyano Akemi would be working at Fang Zheng's home in the future, and she might run into Conan at any time. It would be troublesome if he recognized her.
Once she used the optical camouflage, no one besides Fang Zheng and Shiho Miyano could see Miyano Akemi's true face.
Furthermore, their Personal Terminals also had a Protective Barrier function. If they were harmed, the Personal Terminal would automatically activate the Protective Barrier. Of course, this Protective Barrier was not the kind of flashy, cool-looking shield one might imagine. It was somewhat similar to the electromagnetic Protective Barrier Misaka Mikoto used daily, capable of redirecting the trajectory of incoming projectiles and making them veer away.
Put simply, it was the scientific version of an "aiming-at-the-outline master."
After that, the two sisters' fates changed as well.
First came Shiho Miyano. Fang
