Quantitative Cultivation of Immortality

System? The standard golden finger for time travellers? But this function... Is a bit too shabby, right? Lin Zhou was also a fan of Internet literature in his previous life. He had never eaten pork and had seen pigs running away. Other people's systems can either defeat monsters and upgrade, or they can refine elixirs and weapons. Even if they are not good enough, they can give newbies a gift package, including an introductory exercise or a few healing elixirs. But his quantitative system sounds like a calculator with a spiritual power detection function.
