He believes that it is unfair that a weak person having wealth won't help them become stronger and transcend. He doesn't think it is right that wealth will only cause their early demise. But what he thinks doesn't matter as it is the way of the world.
Fortunately, all hope is not lost for the common people. There is a chance for them to acquire the technique without seducing rich young masters or swearing their lives into the service of a powerful organization. That opportunity is the special regional sect examination.
In fact, that opportunity is one of the lowest that can be acquired in the examination. Those who fail to be recruited by sects can still get the technique. They just need to perform up to a certain standard.
