The group jumped into the hole and Billy felt the mana level increasing again… it wasn't surprising at that point in time. Nevertheless, he felt like the next would be the final sector… you can only pull out so many dragons after showing the wyverns.
After falling for around five minutes, Billy began to feel weird, the temperature was actually decreasing. That was beyond weird since the deeper someone goes while digging downward, the more the pressure and heat increases naturally…
In any case, Billy decreased their falling speed when he saw the bottom of the hole and he saw some things moving there. He wasn't sure what it was yet, but it sure looked creepy.
"What is down there?" Icarus asked.
"Don't know, my eyes can't see it yet," Billy replied. "What do you see Meryl? Your eyes are supposed to be better than mine, being an archer and all that."
"... I can see some snake heads," Meryl replied.
