The underground explosion was naturally the work of Leonard Churchill.
Since he suspected that someone was coming, he didn't just plant bombs upstairs to add an extra layer of insurance, but also in the mortuary.
The structure of the mortuary was enclosed like a can.
It was completely different from the open space upstairs.
There was nowhere to hide even if one were to throw a hand grenade in here.
Bullets inflicted limited damage on a Curse Card Master, but a Demon-breaking Bomb, with its thousandfold destructive power, was another matter.
Just a moment ago, when Leonard Churchill noticed that someone was entering the basement from within the corpse storage box, he immediately chose to detonate the prearranged Demon-breaking Mechanical Bomb.
There was only one bomb upstairs before, but here, there were three.
Without giving the intruder a chance to react, a green flash of fire flooded the entire mortuary.
