After waiting nearly two minutes, a slight noise came from inside.
The sound of footsteps approached one step at a time, and then a voice yelled,
"Who's there?"
Huh?
Is there really someone?
Although they already knew, the team members still widened their eyes.
After all, this was a laboratory deep in the mountains!
Not to mention the general public, even for the team members, it was rare to encounter in a lifetime.
"XN Battle Zone, former Land Air Force 2nd Group flight squadron Jiang Ye, reporting on the orders of General Zhan Youguo!"
An upbeat laughter followed immediately from behind the metal door:
"Sent by Old Zhan? Hahaha, there's hope after all; we are saved!"
Then the metal door opened from the inside.
When everyone saw the person inside, they were all taken aback.
This hair and this beard, could they be braided?
The clothes were also tattered and patched up numerous times.
