From MC's perspective:
A few hours later,
I completed the mission. I have destroyed all the lairs of the monsters. Hereafter, the medicine garden will be safe. Then I walked back to the teleportation circle.
Then I opened the pouch and placed mana stones around the circle. Then I chanted according to the instructions.
Swoosh!
The next second, the magic circle lit. In that same town, I disappeared from the spot.
When I opened my eyes. I found myself at the back of the mission hall. The turbulence was less this time. So the return journey was smooth.
Then I started walking towards the mission hall. After arriving at the hall, under the surprised gaze of everyone. I submitted the mission.
The staff told me the reward will be given later. After getting confirmation from the Medicine Hall. Then I nodded my head in understanding before leaving the place.
