Not really the type of story that I would enjoy. The 'system' is more of a minor cheat that offers a method to completely comprehend written techniques. It only allows the MC to learn techniques that are written down, drawn, or have some sort of visual que left over. Possibly sword scars would work. It does not allow him to learn techniques from watching someone perform it at least not so far. Explanations and lectures are also out. As far as it being a system, he gets a system window that gives him a record of his techniques and cultivation level. There is no menus or store functions. There is no interaction with it either except when he is able to merge two techiques. So I would just call it a cheat with a visual que.
As for story development it starts with the MC captured by bandits and fortunately finds some sort of scribbling on the wall of his cell that provides him a couple of low level techniques. This allows him to slowly overcome the bandits by luring individuals to the prison.
The story seems to be about how the MC is trying to acquire more techniques or higher level techniques. He goes to bookstores looking for books that will trigger his progress bar. He finds a woman with a tattoo that triggers it as well.
I ended up skimming through it because it just did not excite me much. There did not seem to be much draw mentally for me.
