This is still the effect of the primary level. The difference between the primary and intermediate, although just one level apart, is vastly different in terms of effect.

Everyone's ability is different; the Neo-Humans propelled by genetic evolution are akin to the "superpower" characters in novels, separating them entirely from ordinary humans in terms of combat power.
Achieving this level represents the limit of current technology.
Pushing genes further requires civilization to reach a higher level, but Earth's civilization is still far too low—Jiang Cheng can barely apply only one percent of the knowledge and technological references in his mind!
