By performing angle-resolved photoelectron spectroscopy and first-principles calculations, we directly detect inclined Weyl cones in the bulk electronic structure of WP2, which form Fermi arcs in surface states and exhibit chiral anomalies in transport properties . Our results show that the second type of Weyl node in WP2 originates from the crystal symmetry-induced splitting of the intersection of quadruple degenerate bands with a Chern number equal to 2 due to spin-orbit coupling, which is now found in Weyl fermions is the only one. In addition, our findings also provide a new avenue for studying chiral anomalies that may manifest as exotic transport properties.
