Few students moved. They were all present when the detector was discovered. Now that the army had sent people over, how could they not be excited and curious?

Su Fangmei waved at the students, telling them not to follow her, "Go home early and don't hang around outside."

After saying that, she followed Wang Shuning and said, "I'm going too."

Wang Shuning walked to the rock where he slipped and pointed under the rock. "It was right here. I accidentally kicked it. The detector was half exposed from under the rock. I thought it was a bit strange, so I fished it out of the water."

Feng Yunhao asked: "What time was it?"

Su Fangmei immediately responded, "It was exactly 2:45, and we were about to take the students back. When Teacher Wang stood up, he got dizzy and fell into the water."

Wang Shuning nodded in agreement. He didn't look at the watch at that time, but estimated that it was around 2:40.

Feng Yunhao felt uneasy. It had only been half a year since the Fujikino incident, and the other party had done the same thing again, using high technology instead of manual labor. It was really hard to guard against.

"Thank you, Mr. Wang and Mr. Su, for your cooperation. You can go back now."

On the way back, Su Fangmei held Wang Shuning's arm and walked together, "Do you recognize those English letters? Do you know which country they belong to?"

Wang Shuning thought back and couldn't put it together. It didn't seem like a single word. He shook his head and replied, "I don't know."

Su Fangmei curled her lips. "Last year, pirates appeared on the island. This year, foreign detectors appeared on the beach for unknown reasons. It's not peaceful!"

Wang Shuning frowned slightly. Who said it wasn't true? If a real fight broke out, the people on Jinshan Island might be in danger.
