Knocking Begins with the Resurrection from the Dead

Immortal transformation, Qi refining, Zifu, golden elixir... Every state has a "lock of knowledge". In this cruel world where energy flows like an hourglass, time is the most luxurious thing and knowledge is the most deadly barrier. The sect is monopolized, the aristocratic families are strife, and it is difficult for a disciple from a poor family to seek a chance to succeed. He was resurrected from the dead, but his soul was about to disintegrate. Within thirty days, he gathered enough supplies, used his mortal body to sneak into the demon cave, and used a blood sacrifice to bridge the gap in his soul. This is a story about a poor family, walking towards immortality step by step.
