To be honest, under the battlefield-scale firepower coverage, soldiers at levels four, five, and six essentially have no real difference. With space-based cannons, railguns, nuclear cannons, and fortress cannons firing in waves, if you survive the first hit, you won't withstand the second. You still have to die anyway.
But when it comes to level seven military technology, it's different. Like a vampire prince, BYB's Hengchongdu, cloned Iron Soldier Drought Demon, and the Legion's battle mages, they are far superior to humans, almost god-like. Not to mention each has their life-saving skills, but even if they turn tail and run, they can escape to the ends of the earth.
