Green roof.
Roan woke up and the first thing he did was to grab his phone and check the time. "Shit, so much time passed."
Not wasting any time, he jumped off the bed, rushed to the game pod, and logged in.
Grave opened his eyes, and looked at the dark dungeon master room, 'Let's go,' thinking he teleported to the space village.
In the space village, he looked at the gigantic tree, no it was more like a green roof. The tree got so tall and wide that its branches covered all surrounding islands around the testing island.
The size of the trunk of the tree was half of the big testing island. But the thing was, the tree had a weird shape. At some point, it stopped growing tall; instead, branches spread to the sides of the trunk. The high density of leaves made it look like a green plain land on the air supported by a thick log.
