Xiao Chifeng originally wanted to ask Shen Qingcong what she needed all of those items for, but given the things she said earlier, he felt reluctant to ask.
Seeing him like this, Shen Qingcong also thought that these things she would be doing in the future would undoubtedly require these two brothers' help. It might be better to tell them some things upfront.
However, she needed a way to ensure their silence.
Suddenly, Shen Qingcong remembered that after her Mind Power upgraded, she had a few new abilities.
One was using Mind Power to set up a psychic barrier to prevent others from probing and eavesdropping.
Another was a more advanced form of Hypnosis, mind control. She could directly implant mental commands into others, controlling them for her own purposes - a common term for this was a spirit contract.
Thinking about this, Shen Qingcong felt confident. She knew exactly what she needed to do.
