On the Heavenly Machine Pavilion.

Dao Que and Dao Yu sat at opposite ends of the stone table, there was an endgame on the stone table, it seemed that the black chess had forced White to a dead end, the white turtle shrank in the corner of the chessboard, Dao Que pinched a white piece in the middle and second fingers of his right hand, his thumb against his chin, his lower lip pressed against the base of his index finger, staring at the chessboard, his brows tightened.

"My brother's chess skills are really getting better and better. ”

After a while, Dao Que admitted defeat and was a little frustrated.

Dao Yu picked up the sunspots one by one, his movements were very slow, and he was cultivating his mind recently, "It's because you have distracting thoughts." ”

"Perhaps, Xuanjiyi has been turbulent recently, but I can't see the signs clearly, and I'm really a little uneasy. ”

Dao Que said very calmly, he and Dao Que have known each other since childhood, and the two have spent thousands of years together as senior brothers, when the master in order to choose a suitable successor among the two of them, but it took a lot of effort, and in the end, because his personality is more stable than Dao Yu, the title of the master of Tianji Pavilion finally fell on him, but now he began to doubt whether the master's idea was wrong, because in recent years, Dao Yu has become more and more calm and calm, but he has gradually become anxious.

Dao Yu seemed to see through his thoughts, and while emptying the chessboard, he whispered, "Master chose you to be the pavilion master for other reasons. ”

"Really?"

Dao Que smiled bitterly, his eyes wandered in this small stone room, this is the secret place in Xuanji Mountain, except for the personal disciples of Tianji Pavilion, even the worship of Tianyuan Realm can not enter, the square stone room is very messy, the wall is full of calligraphy and paintings, there are four or five stone tables, most of them are full of yellowed ancient books, under the wall directly opposite Dao Que, there are three rows of low bookshelves, on which are stacked with rolls of bamboo slips, just behind Dao Que, there is also a very high seven-layer bookshelf, which is placed with stacks of light and thin stone slabs.

"Of course, because of the curse, our lineage has always been sparsely populated, and there are only two people in each generation, one inherits the position of the pavilion master, and the other serves as the so-called guardian," Dao Yu closed the lid of the chess box, stacked the two chess boxes on top of each other, and said solemnly, "According to the rules, the guardian cannot have a disciple, and the person who inherits the position of the pavilion master naturally has to bear the heavy responsibility of teaching the next generation, I am not good at this matter, only you can do it." ”

Dao Que looked at Dao Yu in a daze, and after a while, he pondered about it, and muttered to Dao Yu, who walked to the side to place the chessboard and chess box, "What do you mean, Master chose me just because I can teach people?"

"Otherwise, you are inferior to me in terms of talent, and you can't beat me in terms of fighting, and in this year, calm and useless again?, not to mention that you are restless all day these days......" Dao Yu glanced at Dao Que, "But you did teach a good apprentice, Bai Yun's talent is better than yours, maybe he will go further than you in that stone cave." ”

Dao Que silently brushed his long beard, ignoring Dao Yu's previous ridicule, he himself knew very well that he was not as good as his junior brother in the cultivation of this path, "Go further...... Actually, I don't know if this is right or not, the so-called origin knot is probably a blessing or a curse for us. ”

Daoyu also quieted down, "Luo Tian is still between the knots?"

"Well, when the situation stabilized, she didn't come out of it, and with her was the rabbit. Dao Que stood up, his long gray hair falling down to the soles of his feet, he slowly walked to the bookshelf behind him, stared at the hundreds of stone slabs on it, and after a while, pulled out one from the upper left, walked back to the stone table, and laid the thin stone slab flat on the table.

"Which batch?" Dao Yu came over, he didn't come to this stone room often, and he couldn't tell the age of this stone slab at a glance.

"Thirty thousand years ago, the writer was ......" Dao Que turned over the stone slab, "a Taoist priest named Su Ningzi." ”

"It's been a long time, what are you looking for it?" Daoyu frowned, "and I don't understand why you've been staying in this storage room lately. ”

"It's just a little uneasy, Su Ningzi is a monk who holds a realm, he not only left this stone slab in the Tianji Pavilion, but also a volume of ancient books," Dao Que's fingers slid on the stone slab, and the ancient characters engraved on the stone slab were very small, "It was mentioned in the ancient books that 30,000 years ago, the Qing Emperor entered the ancestral mountain, read these origin knots, and left a painting. ”

Dao Yu snorted coldly, "So what? No one can understand those knots, not even the Great Emperor, it took us ten thousand years, and the things that were parsed out could not fill ten pieces of paper." ”

"I heard that a little girl appeared on Jianmen Mountain that day. ”

"Little girl?" Dao Yu pondered, "There is a butterfly embroidered on the back?" that guy doesn't know what the origin is, but it seems to be very simple, and the breath is disgusting, but the first demon seems to know her origin, but unfortunately he was in a hurry that day and couldn't learn more. ”

Dao Yuhu looked at his senior brother suspiciously, "You've been looking for that little girl these days?"

"Well," Dao Que nodded, and explained, "In your words, we have worked the knots for many years to fill less than ten pieces of paper, and many of them are trivial and scattered, but after studying for a long time, there are many things that have been firmly remembered in our minds, do you remember? ”

"Thirteen times. ”

The things on the ten pieces of paper, Dao Yu could also recite them backwards, and he remembered very well that the word butterfly appeared a total of thirteen times in the broken knots.

"Do you think that little girl has something to do with the butterfly on the knot?" Dao Yu was a little surprised, "This is too whimsical, isn't it?"

Dao Que shook his head, and he said softly, "Butterfly Xian, Ancestor Shock." ”

This is the first recorded record of a butterfly in a knot. ”

"Butterfly dance, night white. Dao Que continued.

"The second time. ”

"Zu searched for butterflies, but failed. ”

"The third time. ”

"The ancestors cut down the wood, and the butterfly flapped its wings and stopped it. ”

Daoyu said softly, "The fourth and last time there was a complete sentence, and after that, it was just a single butterfly word, and it was not a sentence." ”

"We still can't be sure who the ancestor is, but it's very likely that this is a figure in the realm of the Great Emperor," Dao Que lowered his head and stroked the stone slab, "And what makes an Emperor shocked and searched, and can also stop an Emperor from 'logging', I'm afraid it won't be an ordinary butterfly, right?"

"And I wonder if you've ever heard of the legend of the Butterfly Girl?"

Dao Yu was stunned for a moment, he thought for a while, and shook his head, "No." ”

"In the human race, there are not many people who have heard the legend of the butterfly girl, and there is no relevant account even in my Tianji Pavilion, I found some clues in a handwritten ancient scroll left by the pavilion masters of the past dynasties, seven thousand years ago, the sword fairy had found a girl named the butterfly girl. ”
