My Sentinel Has Become an SSSS-Rank

[Interstellar female protagonist, supernatural abilities, psychic powers, aristocratic military academy] After killing the Zombie King, Qiao Ye transmigrated from the apocalypse into the interstellar era and became the Empire's hidden guide, possessing the highest SSSS-rank mental power. The Empire's generals, marshals, and princes all begged her to soothe their mental power. But because she refused to be monitored and marked, she disguised herself as an ordinary person, secretly soothing mental power to earn star coins and buy mechs. She became the Empire's unknown guide extraordinaire. Lu Chi was the grandson of the number one general in the interstellar era, the first-year top student at the Imperial Military Academy, and a lofty warlord descendant in everyone's eyes, a favored child of heaven in the Empire. Yet he had started hanging around with an ordinary person. Some believed that Ye Qiao was clinging to Lu Chi in order to gain access to the warlords. Only Lu Chi knew the truth. Wait, who was clinging to whom? He simply couldn't beat her! … Sentinels become irritable and quick-tempered during their periods of heightened sensitivity, with highly unstable emotions that can explode at the slightest provocation. But when they are with their beloved guide, they become extremely clingy. They even want to bring their guide to the bathroom, and feel like dying if they are separated from her for even a second. Lu Chi: Qiao Qiao, I'm hot. I feel awful. Qiao Ye: Do you want some water? I'll pour you a glass. Lu Chi: I do. Lu Chi: Qiao Qiao, my arm is so sore. Qiao Ye: Then shall I rub it for you? Lu Chi (obediently): Mm-hm. Lu Chi: Qiao Qiao, I want to mark you. Qiao Ye: Get lost.
