章 533: Defense system (4)

While Billy was waiting for news coming from Icarus, he resumed his training. Still, in the end, he wasn't making much progress, so he wondered if he should focus on improving his tools with tech again. To put it mildly, he didn't trust Icarus's ability to stay focused much, so he wondered if he could make some magic drones. While creating a tool that could fly and be controlled didn't seem difficult, making one that could transmit images from very far away was. His radar on the submarine was precise, but he would need something better. It was a pity since it was a recent invention...

In the end, Billy decided to take a break in his garden, and he saw Sarah enjoying the weather with Helen. It seems that his other wives and kids had left and were walking across town. They were doing that a lot lately since Billy was absorbed in his training arena.

"Good timing. Can you hold Helen for me for a bit?" Sarah asked. "I want to do some light physical training."
