Unlike the conniving Demon Scholars, one of the strengths of the Son of the Moon is their unity.
For the common interest of their race, they can even set aside past grievances - back then, to help Valentine I increase his level, Pengbonazi had made all the Sons of the Moon within the entire Star Antimony extinct.
Alchemists possess the "Charm Dispelling Power" that allows them to deconstruct other's extraordinary abilities to gain power that is uniquely their own. In this process, a large amount of consumables are also needed. The eventual perfection of the "Triumphal Chariot of Antimony" is not unrelated to the sacrifices of these Sons of the Moon.
That is also why the "Triumphal Chariot of Antimony" speaks of the "Path of Transcendence that elevates the animal nature into the divine".
