Bai Xianyan took it and said, "Thank you! But Master Hou, I just saw that there are several doors outside, if I want to come in and get things in the future, how can I get in? ”

Liu Kuang said: "The emperor has explained that His Royal Highness the Crown Princess is coming, just tell the queen mother, and someone will naturally bring you in at that time." ”

Bai Xianyan: "Oh, I know! It's getting late, it's not good to disturb my father again, and I hope that the Hou Ye will go back to help me tell me that the things are here, I am very relieved! Thank you very much to him! ”

Liu Kuang smiled: "Okay, I will convey it." ”

As the group left, as soon as the door to the inner library was closed, there was a sound of the mechanism turning, and there were several clicks.

"Let's go!" Liu Kuang said.

……

In the carriage back to the East Palace, Bai Xianyan took the key and looked around, and asked Huan Chuan: "You say, is there really only this key?" ”

Huan Chuan: "Of course not. The inner library is a real copper wall, whether it is the wall, the top, or the ground, all of which are sandwiched with thick iron plates. If there is only one key, once the key is lost, then it is really impossible to enter, and there must be a spare one from the father. ”

"If, I say if!" Bai Xianyan: "In case the emperor takes the key and wants to go in to 'see', and finds that the door can't be opened......"

Huan Chuan: "Huh? ”

Bai Xianyan: "...... I should only be able to secretly find someone to pick the lock, and I can't ask us openly, huh? After all, it's just me, right? ”

Huan Chuan smiled, grabbed the key with her hand, and pulled her to his knees and sat down: "Hmm." ”

Bai Xianyan leaned on him comfortably: "But, what if he opens the lock?" And what will he do with your treasures? ”

Although the treasure is nominally Bai Xian's dowry, Bai Hexing has already told everyone who should be told that the treasure is actually the prince's.

He brought all the treasures, and all the original gold, and kept nothing for himself.

Huan Chuan said: "It's not so easy to open. ”

Bai Xianyan: "But can't you and Brother Shi Qian open it?" It's not that hard to explain! ”

Huan Chuan said: "I meditate on seven numbers now, can you write the seven numbers I think of, and the order of size is not wrong?" ”

Bai Xianyan: "...... How is that possible? ”

Huan Chuan: "That's the truth. Once the opening mechanism is changed, it is equivalent to replacing the original seven digits with a new one. Even if there was someone as proficient in lockpicking as Shi Qian, it was impossible for him to guess the new seven-digit key inside the bronze door. Only Shi Qian and I know. ”

Bai Xianyan: "That's it...... Then you just said that the inner library is a real copper wall, you have to make a tunnel from this side, can you penetrate it? ”

Huan Chuan: "It's not easy. But there is a way. ”

Bai Xianyan: "What way?" ”

Huan Chuan said: "After digging to the bottom, dig a big pit and settle the whole iron plate. ”

Bai Xianyan: "How long will it take?" ”

Huan Chuan: "A month." ”

Bai Xianyan: "So fast? ”

Huan Chuan: "The straight-line distance from here is not very far, and our earthwork team has always been neat in its movements. ”

Bai Xianyan: "Thanks to all kinds of talented people in our army. ”

Huan Chuan's hand began to wander over her, and he replied a little inattentively, "Hmm." ”

Bai Xianyan slapped him: "What are you doing!" ”

Huan Chuan didn't dare to move.

But after a while, he went to kiss her earlobe again.

Bai Xianyan struggled to get off his leg and sat next to him.

You can hide during the day, but you can't hide when you sleep in the same bed at night.

……

Grandma is beautiful.

The usual appearance is only the tip of the iceberg.

The real moving place, only Huan Chuan in the world knows.
