They're good movies, and unfortunately, they will butcher certain history and events, because it's fiction and not intended to be factual. When I saw the third one, I never noticed any of that but I've never been a fan of Chinese history.

I guess Ubisoft can just create fictional tombs built by Those Who Came Before (The First Civilization) and make them more complex than the traditional tombs that the Egyptians designed. However, I do recall that some tombs had somewhat complex corridors and interiors within, even though the exterior was very simple in design.
