Those people weren't even superpower users and lived at the bottom tier of Beishi Base all day, their personalities gradually becoming twisted and dark. The places they frequented were quite fixed, and Shen Xin fell victim to others' schemes first, her mind unclear, leading her to be thrown here and eventually meet her tragic demise.
Shen Xi's parents died long ago, and the only person he cared about besides his research was his sister Shen Xin. He knew Shen Xin had many flaws but still treated her like a treasure, and even after the apocalypse came, he disregarded his own safety to find Shen Xin first. Now that Shen Xin had been killed tragically, he would not stand idly by!
The others were easier to deal with, but Chu Li had recruited quite a few Spiritual superpower users, and Shen Xi couldn't get anywhere by attacking him with his spiritual power. Besides spiritual power, the only thing Shen Xi could use were those potions; his combat power was insufficient!
