Supernatural + natural disasters + sci-fi + alien arrival
Volume One: A mixed apocalypse, where natural disasters and supernatural events strike at the same time. The protagonist, Zhang Lei, struggles to survive while experiencing it all and raising his ability level.
Volume Two: He enters an underground city, or base, and learns knowledge from the previous era. It leans toward philosophical reflection, with a little basic science, and aims to make the protagonist a thoughtful character.
