The top is semicircular, seemingly irregular, as if it were a door sketched out by a child on this wall.
The door has a wooden texture. Despite being a door in the newborn world tree, it carries an aura of antiquity.
"That wooden door..." Shi Wanyun displayed an expression of surprise.
"Ying!" Keke released his grip on Xu Xin's pant leg and ran towards the wooden door.
Xu Xin looked up: "We haven't reached the treehouse of the world tree yet. Here... is the interior of that root we were just at. We need to go up to enter the world tree itself."
Everyone looked up.
"But, how can this place be so big?" Zeng Tao asked in confusion, "That root is indeed thick, but not this—thick, right?"
She drew a large circle with her hands.
"...Space capability." Xu Xin suddenly spoke, "It's similar to our backpack. It seems small outside, but inside, it's vast."
This treehouse seed had been influenced by Xu Ying and that Xu Xin.
