Chapter 399: Signal Formation Disk

After seeing off Narcissus Brown and her group, Peter Brown simply moved into the factory.

To cooperate with Peter's invention, the military attached great importance to the matter and specifically sent a company of soldiers to guard the place. After Peter moved in, people prepared his meals and he could fully focus on what he wanted to do.

With no one around to help, Peter started operating the machine tools alone in the factory.

Recently, Peter also read a lot of books on communication so the matter was not too difficult for him.

Of course, Peter's main focus was still on modifying the teleportation formation.

The teleportation formation is for teleporting people, and if it needs to be refined, the required materials are very particular. However, Peter only wanted to make a signal teleportation formation, so he did not need to bother with the knowledge in the field of communication.

After trying many materials, Peter finally found several common materials on Earth.
