The Miracle Doctor Call Me Savior

His original name was Harrison, who known as the Herbal King and mastered the medical skills that could bring the dead back to life. He died in a war. But his soul didn't disappear after he died and entered into a young man's body named Zachary, an intern doctor in a small hospital... As Harrison's memory was passed on to Zachary's brain, he continued to save human lives with his skills using Zachary's face. His first patient was the beautiful girl he loved in college. She was dying. He instinctively used his silver needles to operate on her without a doctor's permission and got caught... Would his true identity be exposed?
