From MC's Perspective:
After recovering the mana, I appeared outside. The Snake Monster hadn't left the place. I'm standing close to the body. Seeing that I decided not to move.
The snake monster is hissing. It is trying to find the prey. After hissing, then the monster started to move.
The whole body is moving in a zig-zag manner. Seeing that I leaped off from the ground and landed on top of the monster's body.
Before the monster found out about my presence, I started dashing forward. After a few steps, the snake monster got alerted.
It suddenly raises its head to look at its back. When the giant head turned around and looked at the back. It spotted the prey running on its back.
At the same time, I already entered the spell range. I can cast the magic spell now. So when the monster was looking at me. I simply pointed my fingers at the monster to cast the spell.
