Immortality Begins with Trading Talent Tags

According to the initial skill exchange mechanic, does that mean that as long as you bring someone to near death, with only one breath left, exchanging skills will be free of any cost? At the start, the protagonist exchanges green attributes without sacrificing even a single day of lifespan.

The plot is lukewarm at best, and it even somewhat overshadows the protagonist's fighting power, offering no real thrills. The villainous cult has numerous powerful figures, dozens of them, some with innate abilities and others acquired, yet they seem invincible against our high-level combatants. It's as if they're just padding the word count.

Is the author simply unable to advance the plot? They've given another plot device that needs to be developed; doesn't it feel out of place in your writing?

It's alright, but the cheat system is poorly designed. Reading books is simple, clear, and enjoyable, but with this cheat system, you don't know any of the conditions.

I was tired of reading and, being in a reading slump, thought I could just endure it and read quietly. But then this female lead, I thought there was one ending, then another, and then another, and finally yet another. The female characters were already mediocre, and you keep piling on the bad points.

They've started applying poison. They know that the smelly refugee is problematic, but they don't deal with him or take him away. Are they just leaving him there for people to eat?

The setup failed; even with the same white attribute, the protagonist still has over a hundred years of lifespan to change it. If it were acceptable that the protagonist's initial gray attribute would require so many years to change to a white attribute, the later changes become increasingly absurd.

The author's early chapters were readable, but after subscribing to chapter 256, it became increasingly boring. I mostly skipped through the first 100 chapters to kill time. Hopefully, the author's writing will improve, otherwise I'll stop following this book.

I've been lacking inspiration lately, so I'm hoping you guys can come up with some keywords for me.
