A Max Level Boss Just Wants to Retire

(Time travel + strongest start + fantasy + space + traveling around the world + cold and powerful female protagonist + delicate and frail male protagonist + not nosy + not a virgin) The top killer avenged his best friend and died together, and was reborn as the group's beloved junior sister! She was picked up by her hidden master, and three senior brothers with an unnatural background doted on her. She wanted to lie down, retire, and travel around the world, but she accidentally swallowed a red-blooded ambergris fruit, and after six years of seclusion, she was directly promoted to the rank of Martial Master! After going down the mountain, we ate all over the Snow Wolf Hotpot in Snowfall Kingdom, won an ice sculpture competition award by carving a panda, soaked in hot springs and watched the snow scenery; went to Xingyue Kingdom to go sandboarding, and watched the stars in the desert... But there is always the arrogant grandson of the emperor who is delicate and frail, saying "I'll meet you on the way", but in fact he is just a follower the whole time. I kept holding on and found an excuse to say: "Stay closer to you so that you can protect me." When pirates robbed her, she said to the passengers who asked her why she didn't save them: Why should I save you? I didn't ask them to come? She was indifferent to the evil organization's rebellion, but when her senior brother was in danger, she became red-eyed. While others are busy saving the world, she is busy eating her way through the five countries - betting on stones, hunting game, and visiting markets. Whoever stops her from retiring will be unlucky!
