She is a 21st century killer, codenamed Ni Tian, who is good at using and making poisons. She dares to say that if she is the second best poison user in the world, no one dares to say that she is the first! Do you think she only uses poison? Wrong! Her skills are also top notch! Otherwise, how can it be called "defying heaven"? Maybe the title of "Heaven Defying" made God angry. Damn it, he actually made her travel through time while brushing her teeth! Damn it! Time travel into the body of a useless person with a weak constitution! Forget it, since this loser looks pretty good and can rival her appearance as a modern killer, she'll just give in!
