480 Part 2: Battle Tower Trial (Core House)

From MC's perspective:

It took me some seconds to realize that the environment here is the real enemy. There were no monsters or other creatures here. 

Then I started to release the Gravity Field Spell targeting the ominous flower plants. 

In a blink of an eye, the flower plants were destroyed into pieces. Soon the poisonous mists started to decrease. 

Seeing that I repeated the process of eliminating the flower plants.

10 minutes later,

[Floor 1: Cleared!]

[Get ready for 2nd floor]

[The challenge starts in 15 minutes]

The poisonous mist environment disappeared. Right after, the announcement came.

"15 minutes?" I raised my eyebrows in confusion. The next second, a recovering portion appeared in front of me.

Seeing that a hint of amazement flashes in my eyes. Now I understand the reason for time allocation.
