"It's a Surveillance Array that I've mastered. I need you to set it up together with me. As long as it's set up successfully, it can be maintained for a long period of time."
"As for the effect, with the enhancement of the array, my observation range can reach up to ten kilometers," Number 10 said confidently.
"Ten kilometers? The range is indeed not small!" A surprised voice came from the rune.
"Yes, this is the Surveillance Array that I spent a lot of effort to obtain from the abyss..."
"With the Surveillance Array, I can monitor the entire Black Rock City through it for a long time. There's a very high chance of finding that Perceptor," Number 10 continued.
"This array is really good. Unfortunately, I can't leave now. It'll take at least half a year." Another voice came from the rune.
"Why?" Number 10 frowned and asked.
"I'm chasing after a bloodline master from the Evil Energy Organization. He's very difficult to deal with."
