The Mark on the Nape [Interstellar]

ABO In the year 7930 of the Star Era, ordinary humans were deemed the failed remnants of evolution, with frail bodies and short lifespans. The Federation government settled them in the most desolate star regions, their final graveyard. Shen Xuefeng had lived as an ordinary human for seventeen years. But he often felt that he was somehow different from everyone else. On the night of his eighteenth birthday, overcome with fear and panic, Shen Xuefeng faced strange and unfamiliar changes in his body, utterly at a loss... . Ever since he was old enough to remember, Shen Xuefeng had heard about the prosperous worlds beyond this forsaken star region, and the humans whose civilization was far more advanced than theirs. He had also heard about the mysterious ruler, revered by countless people, who governed all the star regions. Beyond the innate advantages of an alpha, he possessed genes and power that placed him absolutely above everyone else. Like a creator, he ruled over all the star regions. But Shen Xuefeng had never imagined it. On the night of his eighteenth birthday, he would not only experience strange changes in his body, but also meet an older guy... who smelled especially good.
