Completing the Phantom Blade Zero Four Fierce Axes quest takes a long time as it requires you to reach the game's fourth region before it concludes. However, the bulk of the work is a hunt for book pages around Weeping Creek Valley, and you can't find all but one in your first few hours of playing. That last one is a right pain to get as it's locked off in an area of the valley you can only reach after getting to a completely different region of the game. So, if you're stuck at any point of the Four Fierce Axes quest in Phantom Blade Zero, I've laid out all the steps and book page locations below.

Here's how you find all the pages of The "Four Axes" Case Files book and prove that The Axemaster, Peng Meng, was framed by leaders of the Mandate for a rebellion:

Inside a building opposite the Outpost Courtyard Bell. This is just before where the cell you can unlock using the Phantom Blade Zero Cell Key is.

Given to you as part of the Phantom Blade Zero Festering Secret quest by the Blue-Robed Swordsman in the Sha-Chi Tower Base Camp.

Found in the Sha-Chi Tower underbelly accessed via the base camp gate.

Found at the end of the Lady's Cave, which is accessed by crossing the guarded bridge in the Outpost. However, you must wait until you have the Leave None Alone quest after reaching the Village of Lu, the game's third region, before you can cross the bridge.
