In the first year of the great cause of the Sui Dynasty, in the early winter of 605 AD.

At the foot of the Sky Ridge in Liaodong County, Goguryeo, a handsome young man dressed in Goguryeo costumes, with white skin and blue eyes, was shouting something.

"'Little Ferris Array', up!" The young man's face was flushed, his left hand quickly pinched a mantra, and his right hand pointed at an ordinary stone in the snow in front of him, and shouted loudly with the strength of milk.

"Bang"

"Bang"

With two loud bangs, a light blue circle suddenly appeared about a hundred zhang away from the stone, and the circle seemed to have vitality, and at the moment of appearance, it suddenly grew to a height of several zhang, and suddenly divided the circle into two worlds.

"It's done! It's done! Ha ha! The young man shouted excitedly, "Master, look, the formation range of my little skyscraper array has finally expanded to a hundred zhang." ”

The master in the young man's mouth looked at his beloved apprentice expressionlessly at this time, "Well, that's good, but Yu'er, don't be too happy too early, the next thing is the most important." ”

Although the master was also very satisfied, he still didn't want his beloved apprentice to be too complacent.

At this time, the hares that were foraging in the formation did not have the excitement of the teenager and the leisurely of the master.

The young man's formation suddenly cut off the hare's induction from the outside world, making the hare feel restless, and the animal's instinct drove the hare to flee like a fly, but the edge of the formation seemed to have a wall, and every time he was about to escape from the formation, he was knocked back without exception.

"Okay, Xiao Yu, let's start, let's see how your formation skills are." The master said solemnly.

The master will solemnly call his name every time he encounters a major event, although he has long been used to it, but it still makes the heart of this young man named Xiao Yu tighten.

"Okay, this time it will be successful, come on." Xiao Yu thought silently in his heart.

Xiao Yu's right hand had already stretched out, his left hand was still pinching the formula, and his blushing face gradually returned to its original complexion, which seemed to be much easier than at the beginning, but only Xiao Yu himself knew whether it was easy or not.

A quarter of an hour has passed...

Two quarters of an hour passed...

The time for a cup of tea has passed...

As time passed, the light blue circle on the edge of the formation had already dimmed to a zhang high, and although Xiao Yu's face returned to normal, he couldn't help but be secretly anxious in his heart.

"Hold on! Hold on for another quarter of an hour! Even if it's a cup of tea! Xiao Yu shouted in his heart, silently cheering himself up, beads of sweat slowly seeped out of his forehead, and he was blown by the cold wind on the Sky Ridge.

The hares in the formation were still trying to escape from this strange place, perhaps sensing that their lives were seriously threatened, and several hares were also crazy, crashing into the formation again and again.

The time for another cup of tea has passed...

"Hold on!"

"Hold on!"

Finally.

Xiao Yu couldn't hold on.

One of the hares finally broke through the formation and fled after countless attempts, just like a chain reaction, the other hares also broke the formation and ran away, and the light blue circle finally disappeared, and the stone in the middle of the formation also "snapped" and collapsed into pieces.

"Alas! It still hasn't been more than half an hour. Sitting on the ground, Xiao Yu, who was sweating profusely, couldn't help but sigh and looked at his master with a little shame.

Although Xiao Yu's master is close to the age of ear shun, he is deaf and bright, and his eyes on the bridge of his high nose are bright, and he teaches Xiao Yu every day in addition to meditation, and he has no hobbies other than that, as if he is a fairy who does not eat fireworks in the world, plus a fairy with silver hair and more obvious fairy bones. Since Xiao Yu can remember, he has lived in the skyscraper with his master, although he is a master, he is really the same father and son.

Master Dao is a Ferris layman, and his martial arts such as swordsmanship are slightly worse, but what he is best at is formation. It was rare for the master to go down the mountain with him to teach himself this time, but he was not angry, and the formation only lasted for less than half an hour and was hit by a few hares and collapsed, thinking of this, Xiao Yu was annoyed.

"Yu'er, your little Ferris Array is much better than before, but there are still a lot of shortcomings." The master who stood aside and watched Xiao Yu's formation all the way said with a smile.

"Yes, master, the apprentice can't hold on for two quarters of an hour, and it's the limit to barely hold on until now." Xiao Yu stood up and took a breath and said.

"Well, Yu'er, you have to practice diligently, the strength of the hare is much worse than that of an adult strong man, if there is a Taoist person, it is estimated that you will not even be able to hold on to the time of a cup of tea, so, Yu'er... The master who was patiently teaching Xiao Yu with a smile came to an abrupt end, Xiao Yi frowned, the smile just now had long since disappeared, and suddenly an indescribable majesty came to his face.

"Master, you?" Xiao Yu, who was surprised, looked up at his master and couldn't help but be stunned.

MasterWhat's the matter, Xiao Yu hasn't seen the master like this since he can remember, the master's expression is serious, his eyes are wide, a pair of sharp eyes keep looking around, and the momentum on his body makes Xiao Yu can't help but take a few steps back.

"Teacher...", Xiao Yu didn't understand the sudden change of the master, and after thinking about it, he still didn't bother the master again, and countless questions came to his mind, what's wrong with the master? What's going on? But looking at the master's appearance, he obviously didn't want to pay attention to himself now, Xiao Yu had to endure the doubts in his heart, learn from the master's appearance, and keep looking around.

The Motianling that had just snowed was silent, and there were occasionally a few wolf howls in the distance, Xiao Yu, who had been cultivating for many years, could faintly hear the sound of the hunters going up the mountain to hunt with the hunters in Sui'an Town at the bottom of the mountain, but after all, he didn't find the reason for the master's abnormality, Xiao Yu could only breathe at the moment, and quietly waited for the change of events.

Little by little time passed ...

There was silence all around, only the sound of the cold wind constantly blowing in my ears.

What happened to the master?

What is the master looking at?

For the first time, the familiar Ferris Ridge made Xiao Yu feel a little scary.

Finally, the master spoke.

"Come out, I know you're there, you can break my Demon Heaven Array so quickly, it's probably only you, what's the point of hiding?" The master shouted, and the snow fell from the treetops.

Xiao Yu's heart was shocked when he heard this, and he was about to wonder, when an extremely uncomfortable lame cut rhyme (standard language of the Sui Dynasty) came from the distance directly in front of the master and apprentice.

"Amazing, amazing, your formation is still so powerful, I didn't want to meet you so early, who knew that as soon as I broke your formation, you found out, I haven't seen you for so many years, don't come to harm." The uncomfortable voice slowly moved from far to near, and as soon as he finished speaking, a mysterious man dressed in a strange costume and wearing a black veil slowly walked out of the woods not far away.

"Thanks to you, I'm not dead." Xiao Yu's master, the Ferris layman, snorted, and replied lightly.

"Haha, your temperament hasn't changed after so many years, but how did you become the way you are now?" The mysterious man glanced at Xiao Yu as he spoke.

Oh my God, what kind of eyes are these! With four eyes and a pair of eyes, Xiao Yu seemed to have fallen into a deep hole, full of poisonous snakes spitting letters, bright and bright, looking for their prey hungry and hungry, and this gaze was the most ferocious and vicious of this group of poisonous snakes. Cold-blooded, killing is the only meaning of its existence.

"Hmph, you're the same as before, you still like to pretend to be a ghost, what do you mean by wearing this to see me today?" The Ferris monk stared at the mysterious man, and even Xiao Yu could feel the murderous aura on the master's body.

"There's something I want to talk to you about" The mysterious man's voice came again, "I think you must be very interested, especially for him" The mysterious man's eyes are still on Xiao Yu.

Xiao Yu didn't dare to meet the mysterious person's eyes, so he couldn't help lowering his head and secretly looked at his master from the corner of his eye.

The Ferris monk was furious, and just wanted to say something, he couldn't help but be shocked when he looked at Xiao Yu who was secretly looking at him, stepped forward and blocked between Xiao Yu and the mysterious man, and waved his hand at Xiao Yu.

"You go back first, me and... And..., with him, talk about something. For a while, the Demon Heaven Monk didn't know what to call the old man standing in front of him.

With a master in front of him, Xiao Yu's pressure suddenly decreased, "But, master, I..."

"Hurry back!" The master didn't look back and waved his sleeves vigorously at himself.

The mysterious man didn't speak, just looked at the Ferris monk and smiled slightly.

"Don't you listen to what the teacher says? Get back! "The Demon Heaven Monk is really angry.

"Yes, master." Xiao Yu had no choice but to reply, plucking up his courage, but after all, he didn't say anything more, and ran out as if he was running for his life...

"Okay, you can say what you want, what to do, what not to do, you know better than me, I hope you have a sense of proportion." Watching Xiao Yu leave, the Ferris Lay Man breathed a sigh of relief, and looked at the mysterious man with hatred.

"Okay, then I'll make a long story short..."

The skyscraper on the Ferris Ridge is where Xiao Yu and his master live on weekdays, and on the road to the bottom of the ridge, Xiao Yu is running.

Originally, Xiao Yu was worried about his master's safety and wanted to find a place to hide nearby, but after thinking about it, all around him were within the scope of the master's formation, and the master knew his existence in a blink of an eye, and after thinking about it, Xiao Yu decided to go back to the Demon Heavenly Residence first to retrieve his Xingyun Sword.

With the sword in his hand, sitting on the Hu bed, Xiao Yu drank a sip of water and slowly calmed down, although the doubts in his heart were not reduced, but now there is nothing more important than the safety of the master, so Xiao Yu decided to go down the mountain again, if the master is in danger, desperately don't want to, but also protect the master.

With a "bang", Xiao Yu pulled out the Xingyun Sword.

Xingyun Sword was given by his master on his 8th birthday, the sword body is black and unremarkable, but it is a treasure that sharpens iron like clay, and Xiao Yu regards it as his second life.

Xiao Yu held the sword in his right hand, and his left hand stretched out his index finger and ring finger towards the sword body, and a force burst out from the right hand holding the sword, instantly penetrating the entire Xingyun Sword.

Just listening to the "hum", the black sword body has already become snow-white, as if it is whiter than the snow under the Sky Ridge, the white dazzling eyes and the tip of the sword faintly appear a few inches long sword light visible to the naked eye.

"Xingyun Sword, Xingyun Sword, it's up to you today, I don't know who is here today, the master may start with him, 'one day as a teacher, one life as a father', follow me down the mountain, today you must fight for anger." Thinking of the mysterious man's eyes, Xiao Yu couldn't help but shudder, but thinking that the master was in danger, he forcibly suppressed the fear in his heart at the moment, and was about to walk out.

Just walked to the gate, Xiao Yu was just about to go out, and with a "bang", Xiao Yu was blocked back by a resistance at the gate.

Xiao Yu was stunned and stepped forward again.

"Bang", without exception, Xiao Yu was blocked back again.

Now Xiao Yu understands what is going on no matter how stupid he is, the master knows that he will definitely come back and return again with the Xingyun Sword, so he quietly activated the formation ban of the Sky Residence.

After understanding, Xiao Yu was dumbfounded, the formation of the skyscraper was ordered by the master, he made a mistake last year and was punished by the master for facing the wall in the room for a month, and in the middle, he tried his best to get out of this prohibition, and now at a critical juncture, he didn't think that the master would be for himself..., actually..., I knew that I wouldn't come back, what should I do if the master is in danger, thinking of this, Xiao Yu was moved and anxious, tears swirled in his eyes, and he was about to cry...

At this time, Ferris Ridge.

Just when Xiao Yu was anxious and helpless in the Ferris Residence, the mysterious person just now had long since disappeared, and there was only a Ferris Monk in a Taoist robe and silver hair in the snow.

The Ferris monk stood in place, looking up at the sky expressionlessly, muttering to himself that he didn't know what he was saying, and only after looking closely did he notice that on his thin face, two lines of hot tears had already burst out of his eyes......
