I Am Cultivating Immortality Alone in Another World

From the old wizard's novel to the fairy cultivator's novel, it's so straightforward. They don't even bother to change it. The spells just use spell models.

Why do modern novels like to have a system? This book would be pretty good if there wasn't this annoying thing called the system.

I can't stand it anymore. First of all, it is a training system that is "cultivating immortals" in name, but is actually a "wizard/magician" from the inside out; then the first ten chapters are okay, but the rest are just anecdotes; and finally the old storyline, the abyss demon resurrects, the righteous god sleeps, and the protagonist who travels through time saves the world!
