Oil Rat's face changed suddenly, unable to resist picking up the Luoyang Shovel, and hit the wall a few more times while listening closely to the sound coming from within the wall.
After listening, Oil Rat's face showed a hint of anger.
Damn it, they weren't looking for an escape route at all but were being fooled by the designer of this passage!
They had been walking for so long, but they were actually just going in circles inside the Underground Palace, and it turns out there's another passage just next door!
Oil Rat almost cursed out loud, thinking it's rotten to be tricked like this.
His gaze shifted and suddenly landed on the box at Fujiwara Seiho's feet, and a thought flashed through his mind.
If he remembered correctly, when Fujiwara Seiho opened the box, it seemed like there was a plastic explosive inside, right?
Oil Rat had a quick flash of inspiration, considering the possibility of using it.
