Wasteland: Practice Under the Dome

In the era of cataclysm, human beings huddled in the giant domed city. The price of survival is everyone's spiritual power - the city residents practice the art of thinking expansion and become "human batteries" to support the operation of Yongning City. Lin Yan, a nine-and-a-half-year-old orphan, struggles between a shortage of computing power and solidified social classes. When others recite the road map, he is deducing; when others rely on the meditation cabin, he is refining medicine. It wasn't until his uncle was seriously injured and on the verge of death, and the shadow of the city guards shrouded the family, that Lin Yan discovered that his "unorthodox" cultivation method had touched the city's most dangerous secret... "Under the dome, everything is calculated. And what I want to calculate is the fate of this city."
