Because of a chase on campus after returning to China, Liu Nanchuan chased the suspect for ten kilometers without a breath, and was awarded the title of "Liu Nanchuan with Iron Legs", or "Liu Iron Legs" for short. In addition, he led the students with a plain and boring look, like an old scholar who has wiped out all emotions and six desires. Only Gao Ling knew that this man was evil, perverted and wild, and he was truly the most accomplished person in the world.
