"Sir, you've returned." A familiar voice reached Lu Yu's ears, making him feel a deep sense of affection. Perhaps this was the benefit of taking a disciple, at least after traversing through the dust and wind, there would still be someone waiting at the cave dwelling, even if it was just to say you're back, it was enough to comfort the soul.
"Yes, I'm back." Lu Yu's tone carried a hint of sigh, he had been through much recently, met many people, and experienced partings from life and death, which greatly enriched his spiritual cultivation and would greatly benefit his future practice.
This is why Immortals occasionally descend to the mortal world, after all, only by experiencing the baptism of the mortal dust can one forge a resilient heart, and only with a resilient heart can one stay true to one's original self through the endless years, always perceiving the true nature of the mind and thereby glimpse the Great Dao.
