What? Is She a Human Sentinel?

Mingyue, an amnesiac Earth girl, wakes up from the remote star M312. She took stock of her assets: the sleeping cabin, the light mecha, and the incompletely loaded [World Manual No. 163]. No past, no job, no Pentacles. The administrative bureau's test showed that she is a Sentinel with D-level mental power and no mental body. Well, she can at least join the M312 Star Sentinel Garrison. The job is stable, the teammates are enthusiastic and lovely, and her body and mind seem to be born with the fighting ability of a sentinel. This is strange. Based on her detected age of 24, among the long-lived human groups in the interstellar, she should still be studying in the academy, but her current combat performance is like a veteran who has been on the battlefield. What's even stranger is yet to come. She finally got a spiritual body, but it cannot be manifested outside the body; her spiritual sea is really just a sea, and a bright moon on the sea is far away; even if she is not well protected, she is not afraid of the impact of the polluted zone; she is dependent on a cloud of energy, and raising it requires starting from childhood enlightenment... There were too many strange places, and there were more and more. She felt that it was probably related to the lost memory, and she had to find it back. So while searching, I met various sentinels and guides, and gradually I had my own planet world.
