You Said You Can Survive the Tribulation, but You Call This an Immune Response?

[No system + medical wisdom + leapfrog counter-attack + suspense revelation + multiple female protagonists] On a rainy night in Qinghe City, drug shop apprentice Cen Zhuwei saved a seriously injured medical girl. The next moment, the thunder in the sky that originally killed the cultivator who was crossing the tribulation a hundred miles away all turned around and locked the silver needle in his hand. The Robbery Suppression Department sealed off the drug store, and the strong men from the sect came upon hearing the news. Everyone said he saved someone who didn't deserve to live. But what Cen Zhuwei saw was something else - The Tribulation recognizes heartbeats, selects targets, and even remembers people who have tricked it. When others were cultivating immortals, he diagnosed the pulse of Heavenly Tribulation; when others were afraid of thunder, he used thunder to "cure" powerful enemies. Until one day, he heard a heartbeat coming from deep in the earth. If spiritual practice is a disease, is Heavenly Tribulation killing people or curing diseases?
