As the train chugged steadily forward, Bei Feng could feel a trace of discomfort in his chest. He knew that this was an effect of altitude sickness. The further up they traveled from the sea level, the thinner the air became.
Many people would display strong symptoms of altitude sickness if they were not used to it. Instead of enjoying themselves, these people would end up spending their entire holiday lying in bed.
Now that Bei Feng had sealed his blood and Qi, he would naturally experience the pressure of the high altitude like any other person, causing him a variety of discomforts.
The train slowly pulled into Changdu station after a long journey. Bei Feng alighted with a light sigh and looked about with interest. He gazed at the excited tourists rushing off to the various attractions, but did not follow suit.
