The higher that Gu Xijiu climbed, the more ferocious the beasts that she had to fight. Occasionally, there were event traps to swallow any mortals who made the climb.
The Firmament Stone was anxious. The mere sight of the challenges was more than enough to put it off. The place seemed indeed unreachable. For anyone who broke in, he or she would easily be torn apart by the beasts or swallowed as a whole in the hidden traps. He or she would never get to see the top. Only Gu Xijiu could make it past the challenges on the path.
The climb took her an entire day. Finally, she made it to the top. Gu Xijiu defeated a five-colored bird that looked down upon all mortal beings. When the bird caught sight of her on the tree, it was extremely contemptuous of her. It demanded her to leave the tree or she would become its meal.
