Review Detail of kennykangaroo2 in Tempest of the Stellar War

Some bad translations here and there. Every character has some personality that makes them stand out. There's occasionally some smooth brained face slapping incidents. Pretty satisfying rate of progression in MCs power. So, basically humanity with aid of "cultivation techniques" and tech has colonized most of the Milky Way Galaxy forming a number of Alliances, Federations, and Empires with the Solar System Federation made up of Earth, the Moon, Mars being the metaphorical center of Humanity's power. But due to some Galaxy Wide phenomenon caused by the balance of the galaxy being broken cultivation techniques went inert causing cultivators to lose their powers and go insane dying. Powers that weren't apart of the cultivator class stole the cultivation techniques hoarding them for their families and organizations. Moving on there's is some funny happenstances where every power that colonized parts of the galaxy building their own Empires over the course of thousands of years during the "Interstellar Voyage Era" are ALL ancient cultivator families hence 9/10 of the names for Humans throughout the entire Galaxy have Chinese names and if not then its some abbreviated version of a Chinese name or a nickname. Are we supposed to infer that the Chinese are the only ethnicity of the human race? Though looking back I remember an incident around chapter 500 on Titatitan Star where MCs " the 36D"(that's her nickname no cap) female squad lead was being harassed by a "dark-skinned" guy. What I'm getting at is that the MC could be meeting a human who originates from a power many light years away from Earth with genetic diversity that's been separated from Earth for many millennia's and still have a Chinese name. What, did the Chinese conquer all of Earth cleansing all so that only the Chinese remained lol? In the story whenever Earth is talked about it's always "mysterious" this or "ancient techniques of Earth" that like only the Chinese culture exists and is acknowledged on Earth.
