Heavenly Master and Ghost Seeing Worry

He saved my life and my grandpa's life. I originally thought that his appearance was no different from other people, but he took us into another world, another world that we could not escape from. Behind all this, it turned out that there was a huge secret that we didn't know, and this secret would also affect my life. Even long after he entered "there", I realized that I was just a part of his huge plan. In his eyes, he was just dust on the corners of his clothes. Many years have passed since this incident. When I saw him decades later, he still appeared in front of me as young as decades ago, but I was already an old man who was sinking.
