After making sure she was safe, the two of them jumped into the darkness side by side.

A cold wind swept over me, carrying a damp and chilly feeling.

Finally, Xiao Hei Zi patted Jiao Jiao's shoulder, whispered "Stay close," and jumped down first.

Jiaojiao gritted her teeth, closed her eyes, and leaped away, her figure disappearing into the darkness.

The group had just taken a few steps into the cave, their feet sinking into a ground of gravel and wet mud.

Su Qingzhi's heart skipped a beat, and she immediately turned around to check.

Upon seeing this, she was immediately stunned.

Two large, furry brown bears were slowly walking down from the cave entrance.

And among them followed a small but agile and lively bear cub.

The three bears followed silently, without any warning.

When the little bear saw Su Qingzhi turn around, it happily ran to her side.

Su Qingzhi's heart softened. She gently stroked its thick, soft fur and whispered, "Don't do anything reckless. Be careful, stay close to everyone, and don't act on your own."

Strangely, the little bear seemed to understand her words; its ears twitched, its neck moved slightly, and it nodded like a human.

Then, it turned around and obediently ran back to its parents, standing quietly at the end of the line.

And so, the three brown bears silently walked at the very back of the group.

They continued forward for less than ten meters.

The air grew colder, and the walls began to show signs of human carving.

Suddenly, the lone wolf at the front raised his hand to make a stop gesture, crouched slightly, twitched his ears, listened for a moment, and then whispered, "We're here. The lab door is just ahead, about five more steps."
