Just like planned, Theo brought the monsters in succession. Because of their positioning and safety, Theo ended up getting around ten monsters at a time before taking a rest for a while.
In the end, it took too much time to rest, making them unable to clear the entire tunnel within a day.
Theo didn't mind about it as he had expected something like this from the start.
The next day, the rest of the monsters were eliminated.
And Theo had been standing on the edge of the tunnel, looking at the bottom shrouded by darkness.
Agata, beside him, asked, "By the way, there is something bothering me. We have eliminated all the monsters, but with the sound the fight produced, shouldn't the intelligent species underneath this tunnel notice us?"
"Yeah. That's what I'm thinking too. The noise should have echoed through the corridor and gone down this spiral." Theo narrowed his eyes, feeling a bit suspicious.
