Turn on the power and try to use it.

The radar has a color display inside. In order to prevent the signal from being blocked, Yu Hong moved it to the second floor of the stone castle. After some tinkering.

Buzz! The screen lights up.

It was completely black, with a silver pointer constantly rotating clockwise.

Yu Hong looked at it and saw that the lid on the bottom of the radar was lifted, revealing a row of operating switches. From left to right, the first black switch was the power supply.

The second switch is temperature.

The third one is accuracy.

The fourth one is... the Blood Tide Monster. The fifth one is the Shadow!

"This is an improved version... Yes, who is still producing the old version of radar at this time?" Yu Hong looked at the black radar screen the size of a human head, and raised the temperature with his hand.

The switch is on.

Suddenly, the radar screen quickly turned blue, and in the light blue, three small dark blue dots were moving rapidly from left to right.

Yu Hong's heart moved, and combined with the black lizard's vision outside, he determined that the nearest dark blue dot was the black giant that had just passed the camp. Then, he turned off the temperature and turned on the blood tide switch.

Snap. Swish!

Dozens of red dots suddenly appeared on the black screen. They were evenly scattered, but none of them were close to the camp. The entire camp area was like a bare circle.

Nodding with satisfaction, Yu Hong turned off this one and turned on the last shadow switch again. Tsk!

In an instant, the entire screen turned bright red.

Numerous densely packed bright reds surrounded a small piece of black in the camp. It was like a small black island in a sea of ​​red.

"So many!?" Yu Hong was shocked. But he soon felt something was wrong.

"No, if there are so many, how did the transport team get in? From here, there are no cracks around it!"

"No...it shouldn't be like this! This radar should detect shadows based on the red value concentration. The reason why the area around the camp is so red may be because of the wooden bridge behind it and the black ship...after all It is the product of the combination of millions of red values." After careful inspection, Yu Hong did not find any specific small dots on the radar that represented individual evil shadows.

He got up and quickly went to the back to check the wooden bridge, and found that there was no change. The wooden bridge did not erode the formation, but seemed to be embedded in the camp. When he returned to the stone castle, an idea came to his mind.

"Can the wooden bridge pier and the black ship be strengthened into the camp and become part of the camp?"
Chapter completed!
