In terms of theoretical physics, the streets and buildings that can support the movement of "Salamanda III" simply don't exist.
Under the same pressure, the smaller the contact area, the greater the effect produced, and vice versa. This is one of the basic concepts in physics. When applied to mobile vehicles, the heavier the land-based mobile platform, the more it tends to use a tracked chassis. As the mass increases and pressure rises, the width of the tracks also increases accordingly, and in necessary situations, designs with four or six tracks may appear.
Returning to the "Salamanda III", with a mass of tens of tons pressing down on two slender "steel needles", in normal circumstances, either the two shafts acting as walking mechanisms would bend and break, or it would directly sink into the ground, unable to move. Yet, this monstrous machine navigates nimbly and can even run and leap on vertical walls.
This completely defies the basic laws of physics, yet it happens for real.
