Thanks to the efforts of several young people, an explosion-proof door gradually opened with a 'creaking' sound.
As soon as the door opened, an odd smell rushed into everyone's nostrils.
"What on earth is Thomas keeping in there? Why does it smell like that? Have something spoiled due to improper storage?"
Hearing others' skepticism, Thomas only responded with a mysterious smile, foregoing a response and instead chose to stand by the door, waiting for the scent to dissipate.
Perhaps the odour did not linger for long due to the ventilation duct opened earlier, any lingering smell in the air quickly dissipated.
It was only then that Thomas calmly stepped inside, and the others followed him into the second underground floor.
Unlike the neatly arranged boxes on the first underground floor, things on the second floor appeared to be somewhat randomly placed. All were covered with deep green canvas, and no one knew what lay beneath.
