The passage was exceedingly narrow, and the soldiers had toiled all night without altering its tightness. Every single one of them had their fingers chafed and bleeding, but even so, they didn't stop and took turns excavating the broken stones from the cave.
Bang!
Suddenly, a loud noise echoed through the passage, and they heard a soldier exclaim with delight, "We've finally broken through!"
Upon hearing this, the captain, who had just stepped down and had not yet had the chance to rest, hurriedly dashed back into the cave.
The cave, which had been dug over a hundred meters deep, was shrouded in darkness, illuminated only by the faint glow of several torches the soldiers had crafted.
As soon as the captain entered, he saw that the cave, which had been solidly blocked with rubble, had now opened up. He quickly ran over.
"Captain, be careful!"
Seeing the captain approaching, the soldier in charge of excavation hastily warned him.
