Even after finding out about how vast the world was and what little accumulation they had,solar humanity still didn't loose hope and continued their journey.They deployed many different fleets on a large but stealthy scale to remove the remnants of whatever was left of the bisurg civilisation.They first began by directly destroying planets from above with orbital bombardments but they soon discovered it to be a bad idea as the damage dealt made the planets unrecoverable and terraformable for human sustainance.A new organization was created afterwards for these engagements on a minor scale called the Solar Audjudicator Army.It was composed of the normal military force of soldiers who were goods at fighting with their swords and laser guns.Thus,they sent many infantry soldiers to fight the aliens on the planets with their swords and guns as orbital bombardment by warships from space wasn't conducive but would cause plenty of collateral damage which must be avoided at all costs.However they immediately faced a big problem,the bodies of these aliens were a bit stronger than them even when it was not optimised for war.
"Dammit it!,Can't you just die!!,uh!!!"
Though they overcame this resistance,they couldn't help but question whether this organization could keep up with the increasingly more stronger aliens that were to be fought with as this war goes on.They even shuddered as the thought of what champions,technology or resistance they could mount against those low level achievement fighters with the terrifying power they wielded.Though they occasionally met some in the bisurg race civilisation,it took them hundreds of warships which amounted to whole fleets that could resist and kill these cultivators but even this battle always resulted in mutual destruction between both parties which was considered an unfavourable outcome.After successfully eradicating the race and occupying its territories,they refrained from moving to anymore territories and further mused on how they should further develop their infantry grade to a height where planetry resistance wasn't a problem to them.A consensus was made.Some people suggested about using fighter jets and abandoning the normal human body but was faced with tight resistance from their opposition about how good their structure was suited for war even if it was weak.
"Can't you see,even with a weaker body we could still fight better than them"
"Oh pls,spare us the crap,we all know the bisurg race knew nothing about fighting"
"Yeah,all they knew was fighting with their warships directly and avoiding bodily engagements"
"Accept it friendlies,the human is the toughest weapon against all for war"
"Yeah,let's just make this a signature of our race and civilisation "
Solar humanity stopped its expansion and directed more power and research into developing and making the most suitable infantry war platform.Plenty of suggestions were made with some saying they should develop genetic positions that could make them grow very big and becoming as tall as a skyscraper but these suggestions were immmediately shot down as it it would take a long time to realize it and it was also a new field that hadn't been explored.As time went,plenty of researchers brought more results that satisfied their superiors but were not all that great as compared to the other races and would fall at the bottom of line of combat system when compared to other fighting styles of other races.They still didn't loose hope until one day a brilliant scientist announced his idea which would turn into the long awaited salvation.
"Have you thought about making a human body out of superior metals which could substitute for our fragile flesh and contains a human who controls it with his brain with the help of an AI assistant fully bonded to the machine and the human practicing qi cultivation to bond with his machine and become a god,now how's that"
"Even if I'm arrested for spontaneously making such a bold claim,I would rest in peace for such an idea"
"This is it solar humanity,Our chance to become undefeatable,supreme and superior to all fighting tactics has come,our time has come for us to reign aliens,hahaha!!".
