Can Rogue Cultivators Also Counterattack?

I, Zhang De, died unexpectedly and traveled through time into the body of a hard-working casual cultivator of the same name. The original person was deceived by an unscrupulous businessman, took inferior elixirs, and was poisoned by erysipelas. He approached the businessman in an attempt to seek justice, but he was severely injured, and died from the blood attack. I took my place and vowed to avenge myself. Before that, there are still three days before the erysipelas breaks out. Are you going to die just after traveling through time? How am I going to survive?
