Zhou Hao looked around and clicked on human service. A white robot's head portrait immediately appeared on the top of the screen.
"Hello, Sir. What do you need me to help you choose?"
The robot asked politely.
"I need a defensive magic circle that can hide the coordinates. Do you have any recommendations?"
Zhou Hao answered immediately.
"Alright, please wait a moment."
The robot agreed and immediately pulled up the interface. Four options immediately appeared on the interface.
Zhou Hao took a look. The first formation cost 300 million universe dollars, the second one cost 600 million universe dollars, and so on.
Zhou Hao didn't have much money at his disposal, only one billion universe dollars.
Hence, he chose an array worth 90000 universe dollars and asked the robot,""How do I use this thing? what's its effect? can I test it now?"
Zhou Hao asked the robot in front of him.
"It can be tested. Please wait a moment. It is currently being processed."
