Pei You on the side couldn't help but tilt his head slightly and looked at her: "But what's wrong?" ”

"Wait, I always feel like I need to be more careful." He Ling Jiang's eyebrows frowned slightly, Xuanyang would set up a mechanism in his secret passage, so what about Liu Yuan?

She stopped the movement of her hand, and brought Mingzhu to the dark grid again, and investigated it carefully, and sure enough, she found a thin soft silk thread that was almost imperceptible under the dark grid.

Her eyes narrowed slightly, and she looked along the silk thread, and saw that the silk thread started from the dark grid and led all the way to a raised wooden block on the left side of the table.

If others do not know, and rashly open the secret grid, the silk thread will be broken, and the force of the thread tied to the wooden block will suddenly loosen, and the wooden block that is being pulled will immediately retract, as if someone had pressed it on it.

I'm afraid that the mechanism will be touched at that time.

Pei You also squatted down, pulled the silk thread with one hand, and fixed the force in it: "I'll pull it, you open the dark grid." ”

In this way, the silk thread is pulled by someone, and the mechanism can also be avoided.

He Lingjiang nodded, and then started to open the dark grid.

Except for the hidden trap of the silk thread, this secret grid is not too complicated to open, and He Ling Jiang opened it with a slight movement of his hand.

In the dark compartment, a copper box is quietly placed.

He Lingjiang stretched out his hand and just wanted to take out the copper box, but found that he couldn't move.

"What's wrong?" Pei You pulled the silk thread and looked at her.

He Lingjiang used force in her hand again, but the copper box still didn't move, and she couldn't help but be helpless: "This copper box is embedded in the dark compartment, and it can't be taken out." ”

Unexpectedly, Liu Yuan was so careful, so that even if others found this copper box, they couldn't easily take it away.

And the copper box is strong and not easy to break, if you want to open it with external force, it is not easy.

In this way, the only way to open the copper box is to think about it.

The box is not very large, but it is only half a foot square.

The two of them frowned at the copper box at the same time, and stepped forward to take a closer look, the box was nothing unusual, but it was difficult to put a copper lock on it.

The brass lock hangs horizontally on the box, and there is no keyhole in sight.

The lock body is about half a palm long, the style is small, and the workmanship is exquisite. The two ends of the main body are engraved with two small animal heads, which resemble lion heads, with a ring in the mouth, and a grim expression.

There is a long shaft in the middle of this lock, and there are seven rotatable axles on the lock joint, and each wheel axle is engraved with four characters in regular letters, totaling seven groups of 28 characters.

"It's a Tibetan poetry lock." Pei You looked at the box in front of him and said.

There is no key to the Tibetan poetry lock, and there are seven copper hoops on the lock, each of which is engraved with Chinese characters, and only the locksmith and the owner of the lock will know what the combined verses are.

The lockpicker needs to turn the text on the brass hoop so that it forms the correct verse in order for the lock nose to pass through and the lock to be opened.

It is said to be a Tibetan poetry lock, but not all the combinations are verses, it all depends on how the craftsman and the master set it.

The verse may not be beautiful, it may not make sense, but it is the key to unlocking.

He Lingjiang fiddled with the wheel slightly, looking at the twenty-eight characters on it, and each group was engraved with some common greetings.

But these seven groups of twenty-eight words, randomly combined, can form no less than a thousand kinds, how can we quickly and accurately find the correct combination and arrangement?

She tapped her fingers on the copper box.

"Why don't you try?" Pei You looked sideways at her.

He Lingjiang frowned: "This is a thousand combinations, try them one by one, I'm afraid it will take a lot of time." ”

But since this copper box has been found, looking at this appearance, I think there are some things hidden in it, how can there be a reason to return empty-handed.

She sighed helplessly, and said, "Let's try it first." ”

After saying that, she bent down slightly, and turned the axle as she figured it out.

Seeing this, Pei You couldn't help but raise his eyebrows.

Helplessly, He Ling Jiang is really not good at poetry, and he doesn't know what suitable verses to combine in his mind for these twenty-eight words.

She turned around for a long time, and the copper lock did not open.

He Ling Jiang straightened up, moved his sore neck, and said to Pei You, "You can try it." ”

"Okay." Pei You stepped forward, and the poems he read were not small, but this arrangement was irregular, and he didn't know if it was an attempt to write poems, which made him a little confused.

The two of them tossed about a cup of tea on the copper box again, but still didn't figure out why.

He Lingjiang looked up and looked outside, it was not early.

In such a consummation, it is difficult to ensure that no one will find out about the movement of the study.

It's better to write down these groups of words first, go back and think about it, and try again tomorrow night.

She stood up and just wanted to talk to Pei You, but the glow of the pearl in her hand reflected on a painting hanging behind the table.

Between the towering mountains, the clouds and mist are ethereal, there are cranes and mountains and clouds hovering and flying, under the pines and cypresses nearby, there is an old road with white hair, sitting cross-legged under the tree.

Looking at the old man with white hair, He Lingjiang couldn't help but remember that when he traveled with his master, he had met a crazy old man.

When the old man saw her, he grabbed her and didn't let go, but fortunately, the master was by his side, so he drove him away.

She vaguely remembered a poem that the old Tao read casually when she left: "The human body is rare and has been obtained now, and the road is difficult to be clear and now it has been clear." This body is not to this life, but to what life! ”

He Lingjiang closed his eyes and quickly rearranged the twenty-eight words in his mind.

For a moment, her mind suddenly became clear, and then she quickly squatted down and spelled the words on the wheel into a line "More to what is the body", and the seven words were lined up in a straight line.

Immediately after, her hand moved slightly, only to hear a soft "click", and the lock shaft was pulled open by her.

This lock is open!

Pei You's eyes lit up.

He Lingjiang stretched out his hand to remove the copper lock, opened the copper box, and there were several letters and a booklet in the copper box half a foot square.

She glanced at Pei You and took out the things.

The letter had been opened, and He Lingjiang's fingertips moved slightly, and he pulled out the letter inside.

This letter was written to Liu Yuan by someone else, and she lowered her eyes and looked at the contents of the letter with pearlescent light.

"Liu Gong, seeing the words is like meeting. Recently, the situation in the court has been complicated, and the dispute between the parties has become more and more intense, and the cost has also increased. The copper mines in the Nanshan area seem to be gradually shrinking, and I hope that Liu Gong will put more thought into this matter......"

It was a letter to Liu Yuan urging him to ask for copper coins, and he wanted to come to this person who had nothing to do with this Nanshan private mining case!

He Lingjiang hurriedly read the contents of the letter, and when she saw the payment on it, she couldn't help but be stunned.

Pei You leaned over Mingzhu, and his eyes shrank.

I saw that under the letter, there was a seal with the name of the letter writer printed on it.

Xiangquan Mountain people.

Ordinary people may not know, but he does know that this Xiangquan Mountain person is the prince's private name!
