The sound of the pattern made the guard Yan's spirits shocked and his expression was overjoyed. He quickly slid the second piece.

Standing behind the pattern, Ling Luoyu looked at the pattern at his feet while watching the pattern of Yan Shiwei's patchwork.

At the very beginning, when he was looking for patterns, he still hesitated and couldn't make up his mind, but after halfway through, he became more comfortable.

After reaching the ten-odd yuan, I almost didn't even look at it, so I pushed it over.

When the last piece of pattern was pushed up, the guard Yan took a step back quietly, looking at the pattern with satisfaction, his eyes moved slightly.

"nailed it"

Ling Luoyu's gaze wandered across the stone gate and the ground, and when he was sure that it was correct, his brows couldn't help but frown.

"Why there is no response?!"

Generally speaking, when the puzzle of a mechanism is completed, shouldn't it be automatically rotated to open the stone gate? !

Guard Yan turned his head somewhat sullenly: "Could it be...I spelled it wrong?!"

Ling Luoyu took the first two steps, checked the patterns himself, and finally shook his head: "Each pattern has matching lines and faces, you...looks right!"

"If it's right... Is that something we overlooked?"

An unintentional word from the guard Yan made Ling Luoyu startled.

Yes!

Did you overlook something?

Otherwise, Shimen doesn't make sense to stay still!

Her eyes wandered on the stone gate, her eyes moved slightly: "Yes, something must have been neglected..."

But what can be neglected? !

Isn't the focus on these patterns? !

After turning his eyes around for a while, he finally froze in the bottom card slot.

Because it is a jigsaw puzzle, it is destined to have an empty card slot on a stone door.

And above this card slot, there was a faintly visible crack.

At first glance, it looks like Shimen has burst a gap because of its age.

But when he looked closely, Ling Luoyu found it unusual.

"This gap..."

She flicked her fingertips gently, and her eyebrows frowned slightly.

Guard Yan hurriedly came up: "What's wrong? Is something abnormal?!"

"This gap...too straight..."

A gap, straight without a trace of winding, is like a knife cut, rather than a natural line.

She took out a dagger with her backhand and pierced the blade of the dagger hard.

Although somewhat reluctant, but under brute force, he still stabbed in.

After entering, she instantly realized something was wrong.

Because after the initial resistance, it was all loose.

"Behind this... is empty..."

Suddenly she might rush out the dagger to guard Yan, knocking around the crack with the handle.

Around it, there is a place where the sound is obviously different from other places.

Guard Yan also heard the clues, his eyes brightened: "It's really different, the sound of this place is very hollow..."

Is there really something tricky behind this?

Ling Luoyu's palms were a little sweaty for a while!

"Good luck, we may find a way to enter, bad luck... we may encounter a self-destructing mechanism..."

Guard Yan was said to have a cold sweat: "Miss Ling, you... don't scare me..."

Ling Luoyu gave him a white look, and again inserted his dagger into the crack, saying goodbye.

"Crack!"

The area around the crack was split instantly.

"what!"

Guard Yan suddenly screamed, slammed back and sat on the ground.
