Ding Huaiyi rushed into the Bloodline Road while putting on the strange helmet.
As the helmet was put on, gray and white images suddenly appeared on the visor.
These images were actually scenes from the Bloodline Road!
"This device can actually see the outside world in a place filled with dark attribute energy!"
Ding Huaiyi was greatly shocked, finding it somewhat unbelievable.
However, he soon noticed something wrong; the scene in front of him was swaying like water waves.
As figures ran past him, the images became even clearer!
At this moment, Ding Huaiyi instantly understood the principle of this device!
"It's sonar detection!"
As a senior official of the Guangfu Military, Ding Huaiyi was very familiar with this kind of equipment.
This was clearly a process of using high-frequency wave emission to capture reflected signals and reconstruct three-dimensional space information.
And this process had long been studied based on bat bionic science before the apocalypse flood.
