At four o'clock in the morning, emergency doctor Lu Shihan collapsed after the rescue failed. A system that calls itself the "Eye of Hippocrates" suddenly awakens - it can see through lesions and simulate surgical procedures, but it cannot replace a real scalpel. Faced with the pressure of medical trouble, workplace strife, rare cases and death, Lu Shihan must use the power of the system to hone his true skills. This is not a cheating article, but a story about an ordinary doctor struggling between life and death, growing up, and finally taking up the banner of the emergency department. The Hippocratic Oath is still in his ears, and he wants to save more than just patients.
