I guess it depends on what your real question is. You can do the Pyramid of the Sky in Egypt without Pangu's Axe and without Zeneport, although the Axe will help you get to parts of the Pyramid, I think you can complete the tour and get to the Life Fruit without it. I'm pretty sure.
The adventures that lead to the Axe in China, beginning with Confounded Boulder, are fun and took me way more than 2 days. The Temple of Heaven alone took more than 2 days, and the first time I did it, yeah, it is confusing. But Tuatha's Garden in France? that is a maze and a half. To me, it is much more confusing and complex than the Temple or any of the Pyramids, imho.
I love WA and play it a lot for preference. The French tombs are very weird.
