My Runes Can Be Upgraded我的符文能升级

This is generally quite decent excluding one of his summons. It is an earth fairy. He has helped her reach an extremely high quality. Despite that she remains to hold the intelligence of a toddler. Also she is an ungrateful brat. He literally has to constantly bribe her to do something correctly. If that wasn't enough , she can summon earth golem aids which are also behaving like her. It reaches the point where she acquires a skill which requires on belief to be strong. As in her believing to be strong herself in order for the skill to grow stronger. So here we have the MC entertaining that brat to make it believe it is strong (which isn't despite always getting stupidly op items without even performing well).

It literally made me quit the story. If you can exclude those parts with earth fairy then the rest is ok.

there's no information about the novel's story whatsoever. Only his cheat like ability. What kind of description is this?
