Justice Red Master: Ever Seen an Elementary Schooler Who Can Draw Talismans?

[Justice Red Master] One day, Li Haoxian suddenly ascended to immortality, just before the college entrance exams. That’s right, with that sort of floaty, weightless feeling. When he opened his eyes again, he was still Li Hao, only smaller. He had returned to his childhood. But everything around him seemed unfamiliar. What were all these apartment buildings? Weren’t there supposed to be low, single-story houses? Where was his all-natural sand playground? His older brother had somehow become an important figure, conducting research under someone called Dr. Qian? Li Hao stared at the familiar yet strange surroundings, then at the aliens and peacekeeping team before him, stunned. But no worries. What are the Demons? With me here, I’ll make sure none of them ever leave alive! But strangely... why are there so many aliens?
