บท 232: What an Exquisite Box

I am using external force! Didn't I try to twist the key with my hands? But it didn't move! It's impossible to even press it down. What kind of external force do I need?

"What external force? Do you want me to find a hammer and hammer it?"

Wei Na was startled. Doing so would only destroy the box.

"Why don't you try something else? I see a pattern on the key. Maybe you didn't insert the key according to its pattern?"

"Yes, I thought so too." An Jiuyue nodded.

She reached out and was about to remove the key and insert it differently to see if she could turn it.

However, before she could touch the key, she heard a click. The keyhole swallowed the blade of the key, leaving only the head.

An Jiuyue was extremely shocked. This implied that the box could only be opened with the key's weight.

Applying any additional force would not work. That explained why it was useless when she pressed hard on the key.
