From Kira's mouth, Yan Fei learned that in those years, the ape tribes that fled depicted cosmic humans as incredibly brutal. Although it's unclear if this was intentional or simply a recording error, their promotion led the entire ape tribe to be instilled with the terrifying image of cosmic humans.
Kira is not a warrior and lacks strong willpower, so when he sees Yan Fei's figure resembling that of the outer demons, he becomes terrified, fearing the legendary tragic destiny. However, ape tribe warriors undergo special training; they do not fear cosmic humans but rather harbor hatred towards them. This is why, upon appearing outside the solar system, they destroyed Yan Fei's quantum satellite and brazenly advanced inward toward the solar system.
