A medical student who was crucified on the hospital bed with a terminal illness activated the "Medical Codex of All Worlds" system when his life was only 7%. From then on, he traveled through the animation worlds such as "Steel" and "Naruto", trading life for medicine, poison for poison, and fighting for a glimmer of hope on the edge of life and death. He is not a saint, he only wants to survive; he does not talk about benevolence, he only believes in means. However, his cross-border move offended the Guardian Association, which maintains the "order of all realms", and hunters followed one after another - from Ye Shen Shun to Bai Ye, and then to the mysterious arbiter. In Konoha Village, he cracked Orochimaru's bone virus while arranging assassinations against the Death Note world. The disease has not yet healed, but the ambition is already burning. What he wants is not only to survive, but also to stand on the top of the heavens and tear apart the shackles of fate with his own hands!
