The protagonist is invincible at the beginning. There is no female protagonist. He kills decisively and does not hide his identity. Pay attention.

I recommend the following novels to you: The Heavens: Starting from the Hammer Explosion of Wujou and The Saber Saint. These two novels were decisive and didn't have a female protagonist or a hidden identity. Moreover, they were both in line with your given genre. I hope you like my recommendation. Muah ~

The main character of the City of Rebirth concealed his identity because he was a cultivator, but he did not want to be recognized because he did not want to cause unnecessary trouble. In addition, he might also be afraid of exposing his cultivation ability because cultivators were often seen as aliens in society and were seen as threats with powerful abilities. Therefore, the protagonist would try his best to hide his true identity to avoid unnecessary attention.

Many anime works had plots where the protagonist had a strong ability to hide his identity. Here are some examples: Naruto: The father of the protagonist, Naruto Uzumaki, is a powerful ninja, but his identity has always been a mystery. In the story, many characters had hidden abilities such as Uchiha and Sasuke. 2 One Piece: The main character Luffy's father is a lieutenant general, but his hidden identity is "Red-haired Shanks", a powerful pirate captain. In the story, Luffy and his friends faced powerful opponents many times and discovered Shanks 'true identity. 3. Silver Soul: The protagonist, Yin Shi, is an ordinary person, but he has a special ability to transform into various forms. In the storyline, many characters had similar hidden abilities, such as Katsuki Kotaro and Kagura. 4 Detective Conan: The protagonist Conan is a primary school student but he has superb reasoning skills. In the plot, he often found some seemingly impossible clues to discover the truth. Conan's hidden identity was Aoyama Tsuyoshi, a famous detective. These are just some examples. There are many other works that have plots where the main character has a strong ability to hide his identity.

😋I recommend the novel "My Strongest Treasure Chest System" to you. After the protagonist Ling Yun was reborn in the other world, he activated the Strongest Treasure Chest System. Treasure chests could be seen everywhere. After opening it, he would win a weapon that could destroy the world or an invincible divine power. His identity was quite impressive and he had always been very powerful ~ I hope you like my recommendation. Muah ~😗

😋I recommend the following novels to you: 1. 'I'm really the Cult Master.' 2. " Violating Player " 3.
