"The pyramids are actually bases built by an ancient civilization from Earth that has long perished. Although the original versions they built have disappeared in the flow of time, the Egyptians imitated these "miraculous works" and passed it down. The only reason for the popularity of this architectural structure in the Empire is that the pyramid-shaped buildings have the power to gather positive energy from the universe, and most importantly, these energies have a positive effect on the human body."
Major General Fiji smiled and took a sip of water before he continued, "It sounds amazing, but the theory is actually really simple. If you want to make a whirlpool, just poke a hole under a basin full of water -- similarly, if you imagine the positive energy in the universe as water, then the pyramid is the broken basin. It's just a tool that conforms to the special law of the positive energy in the universe."
