This Is My Sister

The boy's heart trembled under Xi Ze's cold gaze. He felt that the smile on his face was no different from crying.

He tried his best to divert everyone's attention, so he did something unexpected.

Everyone saw him take a step back suddenly. With a grand introduction, he pointed at Xi Wan and said to Xi Ze, "Xi Ze, your elder is here!"

Summer was supposed to be lively and noisy but now, other than the scorching sun and the incessant chirping of cicadas, it was as if all the noise in the surroundings had disappeared at this moment.

If this paragraph had appeared in the exam paper, the question would have been: 'What does the chirping of cicadas here mean?'

Xi Ze was silent for a few seconds before he finally broke the silence. "This is my sister."

"Your sister?" Everyone exclaimed.
