บท 137: Beginning floors

Shingi knew that Goblins were the primary enemies of the first ten floors of the Tower. Each floor was enormous, and somewhere there was the Goblins' base. The Tower's energy, which seemed unlimited, created the monsters here as they never stopped spawning. 

There was a limit on how much energy each floor could sustain, and it still counted each monster as that energy until it got killed. 

When one monster got killed, after some time, a new one would spawn; if the Boss of the floor got killed, the spawn time would increase for all creatures of the floor. The Boss would be prioritized in the spawn rate as it used more of the floor's energy to get spawned once more.
