Researchers have studied the tiny effects on fundamental particles with quantum vacuum about electroweak baryogenesis mechanism, and so we can further confirm the existence of the energy basic state field of the universe (EBSF). In this paper, we propose that since EBSF is the basic energy field of the universe, the quantum superfluid state must be the next level of fundamental particle (quantum state). Then, the evolution-developed equation of quantum superfluid state should be nonlinear, which can be expressed by the fraction fractal KdV equation temporarily. This paper reviews the experimental observation of superfluid in the existing physics and puts forward the possible quantized form of KdV equation. One possible form of quantization for vortex line of quantum superfluid is the string theory, so the basic physical scenario and foundation of physics in string theory can be revealed. At the same time, through the analysis of the KdV equation and general solution, the quantum superfluid state as the lowest level physical state in physics can only be described by the topological invariant in topological theory, and its image is not uniform; there are common phenomena such as energy gap, non-closure and wrinkle (folding) in Euclidean space. Based on the physical view of the formation of the universe system, the idea of nonlinear evolution development, and the idea of level emergence theory in condensed matter physics, the authors preliminarily put forward the framework of the hierarchy theory of physics. The paper also analyzes the broad physical prospect of quantum superfluid physics (or new physics). The essence of some physics concepts is further clear, some present physics puzzles that are expected to be solved, but their mathematical physical processing has considerable complexity, and some rigorous proofs need further breakthroughs.
