In 2242 AD, a virus called "Blight" swept across the world, and the vast majority of humans were transformed into "corruptors" who lost their minds and continued to evolve. Ling Xiu, a former civilization data analyst, struggled to survive in this steel ruins. He has only one goal: to take his infected sister who is still in cryogenic dormancy to the legendary final pure land "Aegis No. 7". When he risked his life to obtain a "biological stabilizer" that could slow down his sister's condition, a distress signal he intercepted led him to a crossroads full of unknowns and crises. This may be the only clue to SHIELD VII, or it may be a carefully laid death trap.
