  We show that very clear answers to the queries raised by D. Chen and R. Ni in
their Comment on our recent paper [A. Zaccone, Phys. Rev. Lett. 128, 028002
(2022)] can be found in our original paper already. The paper [A. Zaccone,
Phys. Rev. Lett. 128, 028002 (2022)] is free of mathematical errors, as anyone
can easily verify, and all the assumptions were carefully, and critically
discussed in the paper.
