"How can we be in the morning and evening..." Yang Xiao opened his eyes, the sky was no longer a starry sky, it was a cloudy sky, but what he heard was still the song "Magpie Bridge Immortal". The window was open and snowflakes were drifting in through the window. The air is as crisp as the green bamboo leaves that have been planted in a deep well for five years. The dream turned out to be just a dream, but how could the dream be so real? The real sound of chanting words was still in my ears.
