I'd recommend 'The Concealed Might'. In it, the MC hides his power for a complex reason. It could be to blend in, to strategize for a bigger goal, or to avoid drawing the attention of those who might try to stop him from achieving his ultimate aim.
To gain an advantage. Just like in the original series where he often used surprise to his benefit. In fanfiction, hiding his power allows him to do the same. He can catch his opponents off - guard.
The main character of the novel Tang Sect Feast possessed the powers of a soul master and a profound martial artist. It could not be considered as possessing both light and dark powers at the same time. However, if you like otherworldly novels, I can recommend some for you. For example," The Strongest Shadow God,"" Dark Zaki Ultraman,"" The Free Form System," and so on. Each novel has its own unique plot setting that makes readers unable to stop. I hope you like my recommendation.😄
He could be using basic chakra control techniques to suppress his power. By constantly regulating the flow of his chakra, he can keep his true power hidden. For example, he might be using a form of internal chakra suppression similar to what some ninja use to hide their presence.
I recommend Genius. The protagonist, Ji Xiaotian, did not hide his strength. Instead, he used his calculation ability to calculate the best moves and mental cultivation techniques. Besides, he would not deliberately hide his strength just to act cool. I hope you like my recommendation.😗
Maybe he is ashamed of it. Some past works might not be up to his current standards, or perhaps there are elements in the novel that he doesn't want to be associated with anymore.

There are quite a few light novels with such a setup. One could be 'The Mystic Chronicles' where the MC has a sister servant who plays a crucial role in his adventures.
You might want to check out 'Winds of Destiny'. In this one, the MC and his love interest travel through time and space, encountering all kinds of adventures and challenges. The chemistry between them adds a nice touch to the story.
I recommend the book "Happy Farmer Family: Beautiful Little Lady" to you. It's an ancient romance novel about business and farming. The protagonists can cultivate spiritual power, which is divided into seven levels: red, orange, yellow, green, cyan, blue, and purple. The male protagonist and the female protagonist knew each other in private. The male protagonist would go to the female protagonist's house to visit her. I hope you like this fairy's recommendation.

One possible reason could be for protection. Maybe there are threats out there targeting him, so by hiding his appearance, he can move around more freely without being recognized. For example, if there are rogue ninja who want to take revenge on him for past battles, hiding his face would make it difficult for them to track him down.
