Cui Ciyou's first impression of the Displacement Labyrinth's first floor was not how dangerous its monsters were, but how fragile its surroundings were.
After stepping onto the first teleportation magic circle and being transported,
Cui Ciyou casually slaughtered several waves of Tarantula Deathlords, then keenly noticed that the walls swept by his invisible sword energy had shed large amounts of rubble and dust.
Even a few sections of ceiling grazed by the residual sword energy had developed fine, cobweb-like cracks.
After countless years of being gnawed by insect monsters and weathered by the merciless passage of time, the labyrinth's walls had long since grown dangerously fragile.
I can't use any overly powerful moves.
Cui Ciyou immediately established the first ironclad rule for this labyrinth expedition.
He began running more detailed simulations in his mind.
What would happen if he recklessly used large-scale attack magic here?
If I use large amounts of water magic, with moves like "Great Water Wave," I could easily wash away these ant-nest-like passages and wipe out all the monsters.
But the immense water pressure and seepage could also loosen the ground, ultimately causing a massive collapse throughout the labyrinth.
And large amounts of fire magic, such as "Inferno Explosion," would rapidly consume the limited oxygen in this relatively enclosed underground space.
Then, whether the monsters died or not, we'd probably suffocate from lack of oxygen first.
Cui Ciyou could not help recalling this world's understanding of oxygen deprivation.
The people of this world still don't understand how oxygen works.
They'd probably blame that invisible sensation of suffocation on some unknown "poison magic."
It seemed he could only use precise, targeted moves that caused minimal damage to the surroundings.
His Blue Stream Blade and invisible sword energy were the best choices, provided he controlled their power and
