The royal breed of "Sagali" and below, limited by class restrictions, must rely on hosts. Their main bodies cannot survive independently for long periods and cannot be exposed to air; they cannot lurk among human groups. The divine breed and spirit seed that can detach from host restrictions are limited by S-Class superpower user Yan Ling's life-expending restrictions, preventing them from entering the Solar System.
Chen Xiao'er's overt strategy precisely targeted the awkward situation intentionally created for the "Sagali" civilization. They wanted to plant pieces within Blue Star humans, but apart from human traitors, they must rely more on enslaved races that closely resemble humans.
These enslaved races will inevitably come into contact with various Blue Star civilization media, becoming bridges for Chen Fei to convey special information, bringing his "overt strategy" back to their groups.
Once these "thunders" are planted, even "Sagali" cannot stop them in time.
