😋I recommend " Personal Security " to you. The protagonist of this book is Tao Xu, who used to be a security guard. Walter was the number one expert of the world's most mysterious security company. After he returned to the city, he lived a seemingly ordinary life, but extraordinary people could not be ordinary anywhere. In a certain chapter, Tao Xu's boss refused to pay his salary. In a fit of anger, he smashed the safe with a punch and took his salary. Later, the boss called the police, but because Walter was powerful, the boss did not dare to pursue the matter. I hope you like this book.😗
