"Ah, the sky is really blue!"

On the vast expanse of grassland, sitting in a large carriage, Wang Lu looked up at the sky and sighed heartily at the blue sky.

"Little brother, what's troubling you?" the old man driving the carriage asked under the whistling of the wind.

Hearing this from inside the carriage, Wang Lu couldn't help but feel strange. "What? Why do you ask as such? Big brother, how can you tell?"

The coachman smiled and said, "Today, you have been sighing about the blue sky for twenty times."

"Yes, the sky is really blue…" Wang Lu sighed again, and then laid down in the carriage and stopped looking at the sky. But after a moment, his breath shortened and he became impatient, one by one his worries burst forth and overwhelmed him.
