The two of them began to climb the mountain. The mountain path kept winding up, surrounded by lush trees. The two of them climbed until they were panting. Finally, they reached a forest not far from the small house.
Serena supported her knees with both hands and took a deep breath before saying,
"I saw two footprints, one big and one small, at the bottom just now. They should be the traces of them going up the mountain. They went up the mountain earlier than us, so they should have arrived at the cabin by now."
Emma looked up and saw that the door of the cabin was still open. She was a little unhappy.
"Where's Dave? Didn't you say that he would go up the mountain and guard it before us? Then why isn't he taking action?"
Serena looked around but didn't see Dave. She took out her phone.
"Wait a minute. I'll contact him first."
However, when she took out her hand, she realized that her phone had lost signal halfway up the mountain.
