Yan Ning climbed with difficulty, looking at the black backpack above her head, her face glistening with sweat in the sunlight.

Just then, a familiar voice came, a soft voice carrying a suppressed urgency:

"Sister! Sister! Can you hear me?"

It sounded as if it were coming from a narrow space, with a buzzing echo.

Yan Ning's heart skipped a beat. She immediately stopped climbing, looked up, and shouted back:

"Xiao Shi! Is that you? What are you doing in the bag!"

The black backpack moved slightly, followed by a faint sound:

"Sister, I'm here! I followed you into the bag and didn't come out because I was afraid of being discovered."

"I just took a nap, and when I woke up I was thrown up here!"

Yan Ning felt a surge of joy, and she encouraged him loudly:

"It's so good to have you there! Can you move? Can you move your bag?"

Xiao Shi was silent for a moment, considering the feasibility of the request, before replying:

"I'll try, but the bag is too heavy! It's full of stuff, and I'm not strong enough!"

Yan Ning immediately encouraged him, "Come on, come on, I believe in you! Just make the bag fall down!"

"Okay, I'll give it a try."

Xiao Shi struggled to move his body inside, and the black backpack began to move slowly.

It slowly moved from one side of the private room to the other, each movement appearing clumsy and laborious.

Finally, the backpack moved to the edge of the private room and slowly slid down.

Yan Ning was already prepared. She immediately reached out a hand and steadily caught the backpack falling from the height.

The moment she received the backpack, her heart finally calmed down a little.

Without thinking twice, she immediately started sliding down and then jumped to the ground.

After gaining a firm footing, Yan Ning quickly unzipped the zipper.

Inside, the small stone lay slumped over, looking utterly exhausted.

Xiao Shi, panting heavily, looked up at Yan Ning and said:

"I'm exhausted! Sister, you have no idea how heavy that bag is! The compass and that piece of rotten wood are incredibly heavy!"
