The young master of the Lin family, upon reaching eighteen, underwent the Sentinel pairing process, only to find his compatibility with all the Empire's Sentinels at zero. Moreover, he was diagnosed with a deficiency in spiritual power. As a Guide without spiritual power, he became infamous across the galaxy overnight, a laughingstock of colossal proportions. The Lin family paid a hefty sum to the noble academy to enroll him, out of sight and out of mind. At school, the young master was ridiculed at every turn. He was everyone's target, looked down upon, and easily insulted as a "good-for-nothing." Lin Fu, the transmigrator, faced with such circumstances, withdrew from the noble academy overnight, reclaiming his exorbitant tuition fees and knocking on the neighboring military academy's doors. The Sentinel who opened the door was dumbfounded, staring at the frail-looking little Guide before him. Little Guide: "Hello, I'm here to attend the military academy." Artemis Military Academy had an addition to its ranks—a Guide without spiritual power. The same individual who once became an interstellar laughingstock. On the combined military training competition field, he piloted a mech, slashing through enemies with a dark, lightless steel giant, boldly confronting S-class Sentinels and securing the final victory, stunning the interstellar populace. Everyone knew that Guides, with their fragile physiques, couldn't pilot mechs or engage in frontline combat. Yet, this Guide was an exception. After the training competition, the visiting Brigadier General was nowhere to be found. Half an hour later, when he reappeared, his face bore a bright red slap mark. Fellow officers who came to watch the competition were shocked at the sight of his face.
