In the end, the night shaking light was still pulled by Wen Tingzhan to the library of the Yuansheng Temple, most of the books in the Taoist temple are naturally related to Taoism, the master of the Yuansheng Temple is a very casual person, those spells, the books of the formation are not hidden separately, and they are not restricted from entering, the night shaking light is relished, and Wen Tingzhan is naturally different from her, but some Taoism-related biographies, Taoist magic treasure classics, Taoist historical classics and so on.

After flipping through several copies of Ye Shaoguang, he suddenly looked up and saw Wen Tingzhan holding a copy of the "Ten Directions Treasure Book" reading carefully, and he didn't turn the page for a while, so Ye Shaoguang stepped forward lightly: "What are you looking at?" ”

"Look at this sword." Wen Tingzhan moved the book in front of the night shaker, "It's not like the sword that was taken from the cave that night." ”

"The Sword of the World?" Ye Shaoguang took the book from Wen Tingzhan's hand, and she carefully looked at the record of the Fu Shi Sword, "The sword flies and is shocked, there is no sound and shadow, it is as clear as ink, it is like a green dragon, and the ancient seal is engraved on it: Fu Shi ......"

After reading it, Night Shake closed the book: "Yes, it's this sword." ”

Although it was also night at that time, and it was still a little far away, the night shaker clearly saw that there was a letter on the reflection of the sword body, and combined with the detailed description, the night shaker was very sure that it was definitely this sword.

"You see, the last record of this sword on it was owned by a real person in the Void Valley three hundred years ago." Wen Tingzhan's slender fingers carved from white jade pointed at that line of small characters, and then he pulled out a book from the side and quickly turned to a page, "This Xugu real person I just flipped through it, he was born five hundred years ago in the previous dynasty, and the last record in his book was that he got the Fushi Sword from Mount Tai three hundred years ago, and since then he has disappeared. ”

"You mean that the people in the cave are very likely to be Xugu real people?" Ye Shaoguang instantly understood what Wen Tingzhan meant, that Xugu real person cultivated to the Mahayana period for more than two hundred years, and finally chose Kunlun Mountain to impact the tribulation period, which was also very reasonable. He immediately reacted and asked, "You are here to look for clues about the owner of the cave?" Do you think the pattern in the cave can be found in his body? ”

"The answer is not necessarily, but there are always clues." Wen Tingzhan smiled, "This is a human habit, just like when we get a beloved object, we need to name it, if it is not closely related to the thing itself, it is related to our own preferences, the latter is more important." ”

Ye Shaoguang couldn't help but nod her head when she heard this, she agreed with this point of view, because she was also such a person: "Then have you found a clue?" ”

Wen Tingzhan smiled mysteriously, put the book away and put it in its original position, pulled the night shake light and went back to their room, and then unfolded the picture: "You wait for me for an hour." ”

Then Wen Tingzhan lowered his head, he grinded, while looking at the drawing, and waited until the ink was finished, he dipped in ink, and gently lit up the drawing with a very fine pen tip, he put down the pen very quickly, obviously there were so many circles, the night shake light looked at him and pointed at the center point of each circle, he saw it very accurately, completely unaffected by other overlapping circles, as if he saw only one one, surrounded by a blank space, such an automatic elimination of interference mode, so that the night shake light was shocked.

Ye Shaoguang's gaze followed Wen Tingzhan's pen tip, unable to eliminate interference, after watching for a quarter of an hour, her eyes hurt, and there was nothing in her mind except a circle, she reached out and pinched the bridge of her nose, she silently looked away.

After about an hour, Wen Tingzhan finally put down his pen, he moved his slightly sour neck, and then beckoned to the night shake light: "Shake you to come and see." ”

The night shake light got closer, and there were countless dense dots, and I thought of the sword book last time in Yong'an Temple: "Don't you tell these dots that the size is different, right?" ”

"It's not." Wen Tingzhan smiled and shook his head, "Shake, I read the life deeds of Xugu Zhenren, he is very talented, four hundred years ago, he met a foreign cultivator, and he was defeated by this person in the astrology, since then he has devoted himself to studying the astrology, so I think this picture may just be a astrological diagram." ”

"So many points, it's like it, but there are so many stars, there are countless kinds of astrological charts that can be changed, I'm not as strong as you, I can deduce them, or do you start learning astrology now?" Night Shake looked at so many points, and his head was big.

"No, shake." Wen Tingzhan pointed to the circle on the pattern, "Shake, I drew this picture with my own hands, in the nearly 10,000 circles, there are actually about 400 circles of the same size, I want to connect the center of the circle, it will be the mystery we are looking for, I will draw the final pattern roughly, you see." ”

Ye Shaoguang nodded, this picture is very complicated, if it is messed up, Wen Tingzhan has to draw another one, it is best not to draw it on the original map.

Wen Tingzhan looked at the original picture, he spread out a piece of paper, closed his eyes and thought about it, before he began to write, the night shaking light did not dare to make a sound at all, because Wen Tingzhan did not look at the original picture at all, he should have a three-dimensional space in his mind.

About half an hour later, Wen Tingzhan handed the drawings to Ye Shaoguang.

Ye Shaoguang looked at it, and his eyes suddenly lit up, and he looked at Wen Tingzhan in surprise: "Brother Zhan, are you sure that the center of the circle in the same circle is connected here, is this pattern?" ”

"Hmm." Wen Tingzhan nodded very affirmatively.

"This is the Ziwei Yuan Bureau!" Nightshake Light's heart thumped.

Ziweiyuan is the middle wall of the three walls, and its name was first seen in the "Shi's Star Classic" compiled in the "Kaiyuan Zhanjing". It has the North Pole as its center, and has a total of 15 stars in the east and west domains. The two bows are together, and they are surrounded by a wall. According to the observation records of the Song Emperor's reign, there are 37 constellations, two attached constellations, 163 positive stars, and 181 additional stars.

"But "Song History Astronomical Chronicles: Ziweiyuan"?" Wen Tingzhan asked. He had also read about it when he was reading the astronomical chronicles, but unfortunately there were no notes.

"Yes." Ye Shaoguang nodded, and then wrote Wen Tingzhan in detail about the relevant knowledge of the Ziwei Yuan Bureau.

By the time Ye Shaoguang finished speaking, it was already noon, Qianyang and others came back one after another, and the Taoist children in the temple also began to serve them lunch, Ye Shaoguang couldn't help but eat an extra bowl because he was in a good mood, and saw that Ye Shaoguang was let go, and Qianyang and others even opened their bellies to eat.

After eating, Ye Shaoguang pulled Wen Tingzhan: "Let's go see tomorrow?" ”

"Not at night?" Wen Tingzhan asked.

"No, it's dangerous at night, let's go during the day and leave a message for Changjian Daojun, if we don't return at night, he will naturally come to look for us, just in case." Now is the wrong time, so I can't shake the light at night and pay more attention.
