  The study of massive neutrinos and their interactions is a critical aspect of
contemporary cosmology. Recent advances in parallel computation and
high-performance computing provide new opportunities for accurately
constraining Large-Scale Structures (LSS). In this paper, we introduce the
TianNu cosmological N-body simulation during the co-evolution of massive
neutrino and cold dark matter components via the CUBEP$^3$M code running on the
supercomputer Tianhe-2 and TianNu's connected works. We start by analyzing
$2.537\times10^7$ dark halos from the scientific data of TianNu simulation, and
compare their angular momentum with the matched halos from neutrino-free
TianZero, revealing a dependence of angular momentum modulus on neutrino
injection at scales below 50 Mpc and around 10 Mpc.
