In Honkai, I Have Five Rule Cards

It's so confusing. I've read Chapter 8. I don't even know what the protagonist's golden finger is or what the protagonist knows. Even the protagonist's experience has been mentioned in one stroke. Who should I replace in reading the novel? And the foreshadowing keeps adding. Normally, shouldn't one or two be added to solve the problem and then be added? The two people chatting with the protagonist are dead and don't know what the situation is.

Lily [what]

Come on it's not bad

It's too messy in front 🤦
