Yi Ziyao carefully observed these annotations in the book, and the handwriting was all written by one person, and many of the opinions were comparable to some assertions in modern civilization.

Although it was a quick browsing, all of these contents were imprinted in Zi Yao's mind one by one, and suddenly a thought popped up in her heart, what did the Eight Kings seem to be looking for?

According to the working ability of the people of this era, it took no less than ten years to verify all the local chronicles on the spot, and then compile them into a book, and the manpower invested was no less than 1,000 people, and the cost was astronomical.

It is not the long-cherished wish of several generations that it is a matter that can make the Northern Wei Kingdom invest so much time, manpower, and material resources to accomplish it, but it is a matter related to the lifeblood of the country.

[Master, the first monarch of the Northern Wei Kingdom, is a tribal leader of the northern nomadic country, he led the people to lay down the Northern Wei Kingdom, and only sat on this country for more than 100 years, do you say it can have anything to do with this?]

Zi Yao nodded, [There is too little information to determine, but what must they be looking for? 】

Put down the book in order, unfold a scroll, sure enough, this huge scroll is a map, and it has also been carefully marked on the map, the most detailed all of which are the southern regions of the Northern Wei Kingdom, and almost every small mountain and river is not missing.

It seems that they are looking for a place with mountains and rivers, and they are also searching along the southern part of the country, is it because the climate here is warmer than in the north?

Looking at the latitude of the Northern Wei Kingdom, it should belong to the middle and low latitudes of this planet, and the southern border is already close to the temperate tropics, and the climate is warm, with mountains and water, which is a necessary condition.

Zi Yao unfolded each scroll, there was no more gain, all the scrolls in this secret room were books and picture scrolls related to geography and customs, as a place that the prince visited so frequently, it was a little puzzling?

These are secrets that should not be counted as secrets! In this way, the content should be generously placed in the study, and the problem should be studied to the fullest.

Zi Yao shook her head, searched the entire room again, and thought for a moment on the chair sitting next to the bookcase, such a simple room, only a mountain of books and picture scrolls on the bookcase, Zi Yao sighed slightly.

Holding the bookcase with his right hand, he was about to get up, and found that there was a cold-touch bulge on the bottom edge of the bookcase, Zi Yao hurriedly leaned over to look, it turned out that there were seven gems inlaid on the back of the right side of this bookcase, which were completely arranged in the way of the Big Dipper Star Array.

Hold up the Night Pearl and take a closer look, the surface of these gems is extremely smooth, and there are uneven brightness caused by frequent touching.

Zi Yao's eyes turned, the Big Dipper was composed of the seven stars of Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and Yaoguang. Tianshu, Tianxuan, Tianji, and Tianquan are composed of a fighting body, which is called Kui in ancient times, and Yuheng, Kaiyang, and Yaoguang are composed of a bucket handle, which is called a ladle in ancient times.

Since the architecture here is so in line with the laws of geography and Taoism, then this organ is definitely not so simple and fixed, so it must be in accordance with the rheological laws of Taoism of one yuan, two yi, three cai, four phases, five elements, six combinations, seven stars, eight trigrams, and nine palaces.

So this mechanism just needs to find the order, Zi Yao's fingers never paused, from Tianquan, Tianji, Tianxuan, Tianshu, Tianquan, Yuheng, Kaiyang to Yaoguangzhi quickly pressed the seven gems, and a 'crunch' sound sounded.

From the top of the secret room, a box suspended with wire was lowered, Zi Yao cautiously opened it, and inside was a more delicate red gold round box, shaped somewhat like a powder box used by modern women, Zi Yao used a silver needle to pry open the lock, and gently opened it inside was a rusty round item.

Zi Yao took it out and gasped when she looked closely, the metal object covered in red rust turned out to be a red gold pocket watch similar to the nineteenth century.

There is still this white substance attached to the edge, Zi Yao gently scraped it with her fingernails, and its texture and touch are the remains attached to the armor creature, so it can be seen that this thing was fished out of the sea, but there is no side of the Northern Wei Kingdom near the coast?

Flipping over the back of the pocket watch, there were some small words written with sharp instruments, and when I looked closely, it turned out to be a wedge-shaped text, which surprised Zi Yao even more when I found it.

The original text of the phrase is: "To my dear daughter, I wish you a happy fifteenth birthday!"

Zi Yao checked back and forth a few times and found no results, put the rusty antique pocket watch back into the ivory box, closed the big box of the mechanism, and the mechanism started again, and the entire secret room was restored to its original state.

Zi Yao suddenly realized, it turns out that this is a mechanism that uses balance to open and close!

[What does it mean for the master to use balance to open and close the mechanism?]

Zi Yao has a black line, [Let you read the book and ask me now, I'm not free!]

Qibao pursed his lips, why did he let his master dislike it? Didn't he say that he liked to be humble and studious the most?

Zi Yao came in for a long time, quickly restored everything to its original position, floated out of the secret room, closed the dragonfly mechanism in the secret room, and probed the situation outside, fortunately, the people who were now close to the third watch were already drowsy, and Zi Yao quietly left the study.

I still left from the north window on the second floor, stood on the ridge of the roof, and instead of going out the same way, I jumped towards the Tingfeng Pavilion marked on the map.

Arrive at this courtyard in a moment, this is Qin Muxue's residence, although the original owner does not have any memory, but it is difficult to help Zi Yao, after all, the layout of the courtyard in ancient times is much the same, only the east and west wings of the whole courtyard are resting, and there are only two maids and wives who keep vigil in the attic.

Zi Yao squinted her eyes, she was able to help Ling'er cover up, and also helped her to steal the master and change the pillars, these two people would not be unaware at all, either they were traitors seeking glory, or they were cowardly and cowardly lords, so Zi Yao waved her hand and slept in the sleeping hole of the two.

Floating inside, all the gold and silver jewelry and valuable items in the room were looted, and even some brand-new clothes were not spared, and they were all included in the space jade bracelet.

It's a little regrettable that there was no word of the original owner found in the huge boudoir, so this Ling'er was extremely cautious and had already dealt with it.

Qi Bao covered his face when he saw it, his own master was not going to sweep away that Ling'er, and he wanted to let these two traitors who sought glory eat the consequences! Really offend no one and don't offend women! This is a real insight.

Zi Yao nodded with satisfaction, floated out of the Listening Wind Pavilion, and had already jumped out of the Eight Kings' Mansion in three or five times, standing in the cold wind, Zi Yao paused, and didn't know where to go.
