Blame little turtle
Lucien remembered every survival scenarios he was forced to participate. Some are easy to complete like figuring out the trick behind the monster's deceptive words. Others took days as he get killed many times before achieving his goal.
This mist is one of them.
Back in the Planner Open Space, he needs to hand over five rubies to the giant hamster. The hamster likes the rubies very much. The system told him. In order to move on to the next stage, he had to get the rubies from the vicious giant vulture's nest.
The nest is located at one of the towering trees in the superficial forest. It was as high as the twenty storey building. He failed and fell too many times he cannot begin to count how many times he had to see his sorry blood spilled in the ground.
The vulture was his enemy back then. Whenever he dropped dead, the giant vulture would prey on him. But before it can took one step to eat Lucien's flesh, his wounds would heal instantly.
