"Sure, let me try it," Leng Shaoting said, and used his consciousness to put the knife into his space. He succeeded at the very first time.
"Wow, great! Take it out now," the old man said with a satisfied smile. He used to think that it was troublesome to have an apprentice, but now he felt it wasn't a bad thing to have such a talented apprentice like Leng Shaoting.

Leng Shaoting tried to take the knife out of the Qiankun Bag with his consciousness, and he succeeded again.
"Perfect!" The old man nodded with satisfaction.
