So I Am an Elf Too?

The poor elves on the border identified themselves as goblins, but after leaving the land of elves and embarking on an adventure in the new world, they realized that they were actually elves. "You drink healing spring water whenever you catch a cold. Are you an elf? Well, I forgot. You are indeed." The centaur said dissatisfied. "Wait! You charge three thousand gold coins for the healing spring water here? In our hometown, it charges five copper coins, and there are still many people complaining..." The elf shrugged. "Forget it, after waiting in line for three months, I will either get better or die... I'll find some herbs and healing techniques to make do with it... By the way, the analgesic you used is poisonous - at least to elves." Occasionally, elves will think about some complex problems. "Perhaps the biggest difference between long-lived species and short-lived species is... A long-term plan? You always think that a lot of foreshadowing and growth are meaningless, so you only care about the present, but... I am still used to making a long-term plan for myself." "Also, for immortal species, the marginal significance of any repeatable and reproducible behavior is almost zero, so our ultimate pursuit is often 'unreplicable achievements.'" "For example, cultivating oneself, managing one's family, governing the country, and bringing peace to the world." "I want my friends and family, everyone I know, and even more people I don't know to live a good life and sing my praises - this kind of achievement to me is really, really cool!"
