The advantage of having a large number of people was immediately apparent. Everyone worked much faster. Originally, it was estimated that it would take another three days to dig through, but as everyone's skills became more and more proficient, the tunnel excavation speed became even faster. All the projects were completed in less than three days, and even safety houses were prepared for every hundred meters.
The ice and snow themselves provide some light, so there is basically no need to light fires. This keeps the temperature inside the tunnel at a relatively comfortable level and prevents it from melting.
Everyone brought their belongings into the tunnel, because the temperature inside was much higher than in the tents outside, and everyone preferred to stay inside the tunnel.
Finally, as the project progressed, the last section of ice was cut through.
With a loud "boom," a block of ice weighing tens of tons collapsed to the side.
Large amounts of snowflakes splashed high into the air, and a rumbling sound came from inside the cave, causing a sense of panic among the group, who feared that the tunnel would collapse due to the falling ice.
Fortunately, the tunnel was sturdy enough that there was only a rustling sound on the ground nearby before the noise stopped.
"Phew! We're finally here!"
Lu Yuan let out a long sigh of relief, then turned on his headlamp and shone it outside.
"We've arrived! Sister Hanwen, come over and check if this is the area we need to maintain?"
Han Wen squeezed in from behind and looked outside.
In the empty valley, a giant fan with a diameter of more than 200 meters was completely covered by ice and snow. Because of its enormous size, the snow kept falling and did not completely bury the fan. The outline of the fan could still be vaguely seen.
After shining a powerful flashlight around, Han Wen carefully paddled forward on his skis, with a rope tied behind him that Lu Yuan and the others held tightly, their eyes gleaming.
Not long after, Han Wen's voice came from afar.
"It's definitely the ventilation shaft that we need to maintain!"
