In this work, we discuss the general behavior of anomaly-related MC by introducing a concise formalism. Using this formalism, we explicitly show that the MC in type-II Weyl semimetals is dominated by the electrons around the Weyl nodes [1]. We also show an intuitive explanation of the tilting dependence of the MC [1]. Our formalism also implies that the MC in type-I Weyl semimetals remains robust even when multiple Weyl nodes are enclosed in a Fermi surface [2].
