She uses external force. Didn't she twist it with her hands, but she couldn't move it, and it was impossible to even press it down. It's like this, what kind of external force is needed?

"What external force, do you want me to find a hammer and hammer it down?"

Weina: "!"

He thought, the consequence of doing this is just to destroy the whole box, it has no other effect.

"Why don't you try another method? Let me see if the key has a pattern. Could it be inserted into the keyhole according to the predetermined pattern?"

"Well, that's what I thought too."

An Jiuyue nodded, she thought so too.

Reaching out, she was about to take off the key and put it on another face to see if it could be turned.

It's just that her hand hadn't touched the key yet, and she only heard a 'click', and the key was swallowed up by the keyhole, leaving only a base.

An Jiuyue: "!!!"

It is still carrying this kind of thing, so it is said that the mechanism on this box can only be lowered by the weight of the key itself.

On top of the predetermined weight, even if a little bit is added, it is impossible to find the mechanism on the box, so she pressed it hard before, and it would have no effect at all.

This kind of mechanism is really too ingenious. It is impossible for her to make such an exquisite mechanism.

When there was only one base left of the key, the keyhole carried the key and slowly began to rotate. After a forty-five-degree angle, the key was pushed out a bit.

After waiting for a while, it turned again, and after a ninety-degree angle, it sank again.

An Jiuyue could only hear the slight 'kaka' sound from the inside of the box, which was the sound of the gears in the mechanism being a little slow and turning extremely fast.

After a few spins, finally, the keyhole stopped moving.

There was only a 'nib' sound, and from the side of the box, a two-finger-wide iron bar popped out the length of a thumb, and then there was no movement.

"What's the situation? Is this to pull out this iron bar?"

As soon as she spoke, An Jiuyue started to pull out the iron bar directly.

Next, the keyhole on the box began to rotate again, and after the key was up and down several times, another iron bar popped out.

According to the previous situation, An Jiuyue took out the iron box again.

Twenty-four times in this way, from the upper, middle, and lower layers, each pulls out eight iron bars, and the keyhole no longer moves.

After waiting for a while~www.mtlnovel.com~ An Jiuyue felt that the box should be able to be opened. She held the two sides of the cover with both hands and opened the cover.

"Tsk, this box is exquisite enough."

"That is, if you put it outside, this box alone can be worth tens of thousands of taels of silver." Weina echoed in the space.

An Jiuyue: "..."

What is this with her, a whole greedy soul.

People are marveling at the craftsmanship of this box, but Wei Nan is thinking how much silver is this box worth. No one has this ability, right?

"Can you say something normal?"

"cough."

Wei Na coughed lightly and quickly became serious.

"Master, I think the person who can own such a good box is definitely not an ordinary person. Please take a look at what your dad has left for you, right?"
