Oh, seeing that you mentioned God's World Editor, I'm going to recommend a novel that looks like it to you! It was the Heavenly Dao Editor! The similarity was that the protagonist also had an editor that could edit his own strength and abilities. At the same time, he could also move around in the foreign world. I hope you like the plot of this novel! Muah ~
In time-travel novels, a godslayer usually referred to an existence that had superpowers or could threaten the gods. Because these characters often displayed great strength and wisdom, they were regarded as legendary characters in the entire novel. However, why was the God Slayer an existence that the gods feared no matter which world it was in? This might be related to the plot and setting of the novel. In some novels, the ability of the deicide could be produced through mysterious magic or special technology. This ability might require some special conditions to be able to display, such as a strong psychological quality, extraordinary wisdom, and superb combat skills. Therefore, these god-killers were regarded as invincible existences in the entire novel, which made the other gods feel pressure and fear. In other novels, the deicide might achieve his goals through some mysterious means or plans. These methods could include deception, threats, sabotage, or other actions that violated the laws of nature. Because these actions often involved the existence of gods, other gods also felt fear and unease. In short, the reason why the godslayer in the time-travel novel was feared by the gods in any world might involve the plot and setting of the novel, the setting of the character's ability, and the behavior and motivation of the godslayer.
