Fu Xiaoli doesnt have Mountain level durability, but her final attack might have that Attack Potency (more than Mountain actually), as it was stated to have the whole weight of Edelberg, a 9000 meters Mountain.
Xiaoli runs towards Stella and delivers her left fist directly at Stella. At the same time, Stella swings her sword down towards Xiaoli. Xiaoli's fist, which is powered by the dragon power strengthened tens of times by 'Kirinkou' and the whole weight of Edelberg by 'Taizan', collides with Stella's 'Katharterio Salamandra' |
And yes, Stella did cut the Mountain, creating a huge valley in the process.
Stella then says that if Xiaoli is heavy like a mountain, then she will just cut the mountain. In an instant, a flame of light bursts out from inside 'Laevateinn' and cuts Edelberg into two. Later, a huge cut mark that spans from the camp site to the base of the mountain is visible and Xiaoli who had lost consciousness fell into the huge cut mark's abyss. |
She only cut 6000 meters though, the camp site was at a 6000 meters altitude.
1- The point is that Ikki's aura doesnt disappear, he only tricks his opponent. Other people can see him, like how everyone saw Touka getting close to Shizuku except for Shizuku.
4- The point of this is showing you that a Desperado's aura can be overcome depending on the opponent. It might work on someone like Ichigo who throws the towel when he sees someone way stronger (like how he did with Aizen), but not with someone like Goku (no explanation needed here).
5- Desperados can manipulate "Fate", like how Edelweiss desired to hurt Stella a little and she started getting cut by invisible blades or the paralisis they can generate when they want to stop their oponents (like how Ikki did with Iris). I thinks its a way of causality manipulation, yes, but it might be limited.
They were exchanging attacks. Stella surpassed Fu Xiaoli's attack (which was stated to have the whole weight of the Mountain) and cut the Mountain from the camp site (6000 meters altitude) to the very base of the Mountain. She cut Edelberg into two, like how the summary says.
