397 Chapter 397. Surprise Him

"Let me see."

Su Qing took the box and looked at the keyhole. The keyhole of this box was different. Other keyholes looked like keys, but this one was round and shaped like a bell.

Su Qing removed some plasticine and squeezed it into the keyhole to ensure no mistake.

Qin Feng stopped drinking when he saw Su Qing's move. He stared at it with all his attention but couldn't understand what Su Qing had stuffed into the keyhole.

Ji Shuisheng didn't understand either. The thing Su Qing held looked soft, like mud, but different. The mud was black, but the one she was holding was purple. The more she pinched, the softer it felt.

"Will it block the keyhole?"

Ji Shuisheng was a little worried. If it were blocked, duplicating the key would be even more difficult.

"It won't."

Su Qing replied calmly with a firm voice. This made Ji Shuisheng's anxious heart drop to the ground as he focused on Su Qing's operation.
