Upon hearing the report from his subordinates, everyone immediately gathered around.
De Gaulle impatiently grabbed the climbing pick and struck twice more at the previous spot.
Indeed, unlike the crisp sound of the solid rock wall, the sound here was notably muffled, indicating there might be a space hidden below.
De Gaulle's eyes lit up and he immediately instructed, "Find where there might be a gap around!"
The subordinates immediately scattered and carefully searched around the rock wall.
After a short while, one of them suddenly shouted, "It seems to be here!"
Everyone quickly gathered again, and saw a nearly ice-level gap at the bottom of the rock wall, close to the ice cap.
Once the ice debris was cleared away, a gap as thick as a finger could be seen.
De Gaulle crouched down and placed his hand near the gap, faintly feeling that there might be wind blowing from inside.
His eyes brightened even more, and he quickly turned and shouted to his men, "It's right here!"
