Under One Person: Join Anywhere and Rectify the Ten Guys

[Rebirth + no system + invincibility + single female protagonist + easy] Mu Yu, as the most powerful thief in the Galan Empire, died together with the sacred dragon in the final battle. When he was dying, his body was soaked in the dragon's blood, and his eyes gradually faded as he looked at the sky... When he woke up, he found that he had come to a strange world. After more than twenty years of relatively boring life, he joined the company "Everywhere Access" by chance. When asked by his only partner what his innate power was, he was a little vague, "I'm more resistant to beatings..." Mu Yu's innate ability, which is also his biggest trump card, is that the blood from the sacred dragon gave him a gift in addition to strong physical fitness - "Magic Immunity", and coincidentally, "Magic Immunity" is also effective against "Qi".
