"Hehe, you've already pointed out that it's just a martial arts novel. Are you really taking it seriously? However, if we look at it from another angle, what's said in martial arts novels isn't completely without sense. It's true that people's meridians are naturally interconnected and that breath circulates automatically through the Twelve Regular Meridians and the Eight Extraordinary Meridians. But the size and resilience of each person's meridians and the strength of their breath vary. It's like the world's rivers—each river has its own size and flow rate."
