The First Sword World

As a special soldier, Xia Lin died gloriously in a drug raid. After his sacrifice, a systematic female voice appeared in his mind: "The first sword world, the second gun world, the third art world, the fourth dark world, the fifth sword world, the sixth light world, please choose the world of reincarnation." "Whatever." Xia Lin said with relief. He was dead anyway, and he could go to any world in reincarnation. The system replied: "The world is randomly selected, the gender is random, and the chaotic knife world enters." Next, how will Xia Lin, who becomes Xia Linling in another world, use cultivation to solve the complicated mysteries of this world step by step?
