Gu Yunyun's mind turned, and she forcefully pulled Gu Tiantian.
Gu Tiantian was stunned, instinctively pulling back to prevent herself from being pulled down by Gu Yunyun. However, she didn't expect that merely controlling her own body slightly would cause Gu Yunyun to fall directly to the ground.
With a loud thud, it startled Gu Tiantian.
Above her head, she heard Grandma Gu gasp.
"Yunyun!"
Gu Tiantian froze, instantly understanding.
Quickly looking at Gu Yunyun, she caught sight of Gu Yunyun's face filled with smugness as she looked at her.
Gu Tiantian was furious, but if she confronted Gu Yunyun at this moment, Grandma would only think she was becoming more and more disobedient.
Seeing the defiant look in Gu Yunyun's eyes, Gu Tiantian smirked angrily.
"Sister Yunyun, you're getting more and more skillful!"
As she spoke, Gu Tiantian walked over to pull Gu Yunyun up from the ground.
