You are literally describing the Area vector, not a pressure vector. Pressure at a point in a fluid is isotropic i.e., it acts equally in all directions. It does not have a native arrow attached to it. When that fluid interacts with a surface, the resulting Force vector is calculated by multiplying the scalar pressure by the area vector. Here pressure is the scalar multiplier that scales the magnitude of the force. The direction comes entirely from the surface's normal vector. If pressure were already a vector, taking the product of a 'pressure vector' and an 'area vector' to get a force vector would violate basic vector algebra. You are confusing the effect (force) with the cause (pressure). Even if you still don't believe me, just do a basic google search bro 😭. I literally do nothing other than study, the fact that pressure is a scalar quantity is one of things that is taught to us in the first chapter itself.

Right...

For those who don't know this character is from one of the oldest wuxia novels, released in 1967.

Maybe that's why he's boasting about the beauty

Pressure is not a force, it’s a scalar quantity defined as thrust per unit area. It has magnitude but no unique direction. A fluid at a point will exert pressure equally in all directions. The direction only comes into play when you introduce a surface, because the resulting force vector acts perpendicular to that surface. In other words, the direction depends on the orientation of the area, not the pressure itself. Also, that 'universal framework of fundamental vectors that compromise [comprise] all things' is pure pseudo-intellectual gibberish. If you want to go beyond a scalar, pressure is treated as a component of a tensor (the stress tensor), not a vector.
