I Rescued People at the Scene of a Car Accident, but Got Caught by the Police?

The tunnel collapses! More than a dozen cars collided with each other at the entrance of the tunnel, and the inside of the tunnel was like a purgatory on earth! But there was no doctor at the scene! Fang Zhichun, who was sitting in a long-distance bus, was trapped in front of a tunnel. He, who had studied medicine for eighteen years, immediately launched a rescue operation and boldly went deep into the tunnel! They rescued a man who was unconscious due to head trauma, a female driver who suffered multiple fractures throughout her body, and a baby who only survived because his mother risked her life to protect him! After walking out of the tunnel, he learned that it would take more than an hour for the ambulance to arrive. Fang Zhichun resisted doubts and continued to use the medical skills he had learned to save those patients who were in critical condition! He used gold needles to bleed, cut the chest and set the bones, and he even took out a scalpel to slit the throat and intubate the person! The ambulance finally arrived, but unexpectedly there was a team of policemen accompanying it! "Do you have a certificate?" "No!" A handcuff was cuffed on Fang Zhichun's wrist: "You are under arrest!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
