If I remember correctly, the 14 chapter of psv should be the 1 1 chapter of xbox360. What's the use of that avatar? You can take it to the designated place for interactive installation (there is a stone statue with its head cut off). Then you will get blue soul and blood.

As for the armory in the second chapter, the second chapter can't be opened, which is also 14. You can't open it until you get the armory key of Wu Yong's room. After killing Luo Cha array, there is a whirlwind shuriken in it. I forgot whether the psv version is available.
