Because in addition to the Chinese characters, this letter obviously has the content of Mongolian or Manchu. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Taking a closer look at the content of the Chinese characters, Han Yue was even more surprised and shocked.

The surprise was that this letter recorded the detained goods of Hong Leong Commercial Bank, and the shock was that someone wrote this letter to Cui Zuyao, and asked him to transport this batch of goods from Hong Leong Commercial Bank to Nanguan in Jinzhou and hand them over to a Houjin man named Tuhai to receive them!

Although Han Yue knew that the final flow of smuggled goods in Liaodong was the Houjin ruling area, and even Xiao Yishan vaguely mentioned that Fenglong Commercial Bank was also engaged in smuggling trade with the Houjin people, but Cui Zuyao was a general of Lushun and a general of the Ming Dynasty, and he even had direct contact with Houjin, and what was even more shocking was that the person who wrote a letter to Cui Zuyao revealed that he had a close relationship with the Houjin Tartars, and even secretly tried to let Cui Zuyao take refuge in the Houjin Tartars!

Han Yue didn't know what Cui Zuyao thought after seeing this letter, but he knew better than anyone the importance of Lushun City, if Lushun was really dedicated to Houjin by Cui Zuyao, then the rest of Dongjiang Town would completely lose contact with the Ming Dynasty, and also completely lose the material support of the Ming Dynasty, and it was only a matter of time before Dongjiang Town was destroyed.

Is history really how it develops?

But wasn't the loss of Lushun and the final destruction of Dongjiang Town a few years later?

Han Yue didn't know where those details were going under the general trend of history, but when the truth appeared in front of him, he was still shocked beyond words.

Just as Han Yue was trying to recall the clues of historical details, there was a slight sound of footsteps in the verandah, Han Yue put away his thoughts, blew out the dim oil lamp, sorted out the letters and bills on the ground and put them into the mezzanine, and gently pushed them to restore their original appearance.

The visitor stopped at the door of the study, and then the sound of unlocking sounded.

Han Yue cursed in his heart that he was really unlucky, and after looking around, he found that there was no better hiding place, only behind a screen to hide, and he flashed behind the screen without hesitation.

The door to the study opened.

The visitor gently pushed the door open, and there was a slight creak, then there was a pause, and the creak sounded again, and the door of the study was gently closed, as if it were still clasped from the inside with a wooden bolt.

Han Yue hid behind the screen and held his breath, listening to the movement with great concentration.

After the visitor entered the study, he walked straight to the bookshelf, and Han Yue saw through the hollow carving of the screen that the silhouette of the back was vaguely a woman!

Han Yue breathed a sigh of relief, after all, the woman is weak, and it is easy to subdue if she is discovered, if the person who comes is the guerrilla general Cui Zuyao himself, Han Yue is really not sure that he can escape after being discovered, after all, a guerrilla general who can do it from the third grade is by no means a good person.

In the middle of the night, why did this woman come to Cui Zuyao's study? And he didn't even light the lamp, and he seemed to be very careful that others would find out, could it be that a certain maid had the audacity to steal in the night?

Han Yue carefully observed the woman whose outline was somewhat blurred, only to see that she walked to the bookshelf, seemed to hesitate for a moment, then turned her head and looked around vigilantly, and then groped with her hand in a compartment in the middle of the bookshelf.

Bang~, the bookshelf slowly moved from both sides.

It turned out to be a secret door! Han Yue was taken aback.

The secret door slowly opened until a man-high doorway in the wall was revealed, and the woman looked around vigilantly to make sure that no one had noticed, and then took out a fire fold from her bosom, took a lantern and lit it, and the black doorway immediately became bright.

The woman no longer hesitated, and walked into the doorway with the lantern, and slowly disappeared into the darkness, and the two rows of bookshelves slowly closed after the woman disappeared, just like normal bookshelves.

Seeing the woman disappear into the secret door, Han Yue flashed out from behind the screen and walked gently to the bookshelf.

He is not surprised that he has seen similar scenes in many TV dramas and movies in later generations, what he is curious about is who the woman is, where does the secret door lead, and what is in it?

Intuition told him that the secret inside this secret door must be related to Xiao Siqi, maybe Xiao Siqi will be locked inside.

Han Yue made up his mind, feeling that he couldn't leave without any gain tonight, and time was pressing, Xiao Siqi was in danger and he had to rescue her as soon as possible, for this reason, any adventure was worth it, not to mention that everyone's heart had a curious side, and the secret inside this secret door was also attracting him invisibly.

With the memory just now, Han Yue found the grid on the bookshelf, and then reached out and groped inside, but the strange thing was that this grid was usually unremarkable and did not find any KitKat mechanism.

A little puzzled, he had to carefully light the small oil lamp on the pineapple wood desk, and by the slight yellow light, Han Yue saw clearly that there were a total of seven well-bound books placed in this grid, namely "Jia Yiji", "Shuo Yuan", "Yutai Xinyong", "Sou Shen Ji", "Qujiang Ji", "Yuan History", "Fan Wenzheng Gong Ji", these books except for "Sou Shen Ji" have been read, the others have only heard a little in the university, and do not know about them.

Even so, Han Yue also felt a little puzzled, because these seven books are fundamentally different types, and the ancient literati were very particular about the placement of the study, and they were generally placed in an orderly manner according to various classifications, which was also a respect for the crystallization of the wisdom of the sages, even if Cui Zuyao was a very big and coarse person, the housekeeper, staff or cleaning maid at home would not make this kind of mistake.

Han Yue felt more and more that this grid for placing seven books was a little strange.

Approaching with the lamp, Han Yue observed carefully, and sure enough, he found something strange, it may be because Cui Zuyao, a big old man, has not liked to read books for a long time, or it may be because there are a lot of his private secrets in the study, so the maid is forbidden to come in and clean regularly, and the entire bookshelf is covered with a layer of dust, but there is no dust in the position of the three books of "Shuo Yuan", "Qujiang Collection", and "Yuan History", which shows that someone often touches these three books.

Han Yue carefully pulled out the "Qujiang Collection" in it, and when he didn't completely pull it out, he felt that the feeling was wrong, obviously heavier than the paper, and after Han Yue pulled it out, he found that it was actually an unknown wooden board wrapped in the book cover, and there was a small square protruding from the side.

Han Yue looked into the gap again, and sure enough, there was a depression the same size as a small square inside the bookshelf, similar to a key and a keyhole.

He also pulled out half of the "Shuo Yuan" and "Yuan History", and its situation was the same as that of "Qujiang Collection", after the three books were pulled out, the bookshelf creaked~~ Slowly separated, looking at the wall exposed in the middle after the bookshelf was separated and the obvious incave mark on the wall, Han Yue had already figured out the setting of this organ.

Han Yue inserted the three books one by one in order, and sure enough, the intaglio on the door hole on the wall slowly lifted up, and soon revealed a dark piece inside, Han Yue carried the lamp and shone it, and found that two steps into this doorway was a staircase leading to the bottom.
