Spring returned to the earth, the ice and snow melted, the water of the Bixi River gradually rose, and Xia Yun also broke through the second layer of the Qi Refining Period and advanced to the peak of the third layer of the Qi Refining Period. However, he still didn't catch up with Lin Ling. After the teachings of the Bixi Fairy, Lin Ling's cultivation of the three of them also worked a lot harder. The current Lin Ling had advanced to the fourth layer of the Qi Refining Period, which was the early stage of the middle of the Qi Refining Period.

When you reach the third level of the Qi Refining Period, you can learn to fly with Edgeworth. One day, Xia Yun was called to his room by Fairy Bixi and handed Xia Yun a flying sword.

"Yun'er, this is a medium-grade spiritual weapon, which can accompany you until the foundation building period. When I go back, I will practice seriously. Remember, the reason why it is called a spiritual weapon is because the flying sword has spirituality. You have to communicate with the flying sword from time to time, so that it will be easy to use. ”

"Thank you, Master."

Looking at the back of Xia Yun walking out of the room, Fairy Bixi sincerely liked her disciple who had just started. The eldest disciple, Song Chun, is more than strong and less flexible. The second disciple Wei Xiaoxia is more than honest and clever. The youngest Lin Ling, although he is clever and wise, is just too young and playful. Only Xia Yun has a calm heart and a soft appearance, but he is firm in his heart. Coupled with his unique qualifications and consistent hard work, Fairy Bixi has reason to believe that his disciple will definitely be able to go further and further on the path of cultivation, and may even surpass him in the future.

Xia Yun, who returned to the room, sat cross-legged on the bed, put the flying sword given by the master on his legs, and looked at it carefully. This sword is about two feet long, the sword body is slender, faintly pink, and the double blades are as thin as cicada wings. After looking at it for a while, Xia Yun wanted to give this medium-grade spirit weapon flying sword a name. At that time, I forgot to ask the master, so I had to take it myself.

Xia Yun remembered that when he was a child, his grandmother once told a story about a sword fairy to himself and his sister. It is to the effect that a girl who has been practicing flying swords with her master since she was a child, when she grows up, she will eliminate violence and help the poor. She is known as a heroine among women. Xia Yun still remembered that her grandmother said that the sword fairy was called a red line, and at that time Xia Yun and her sister didn't understand, why did they turn a sword into a line? Grandma said that when the legendary sword fairy sent out a flying sword, others could only see a red line flashing, so it was called a red line sword. Because of this, some people also call that sword fairy a red line girl, or a red line girl.

After thinking about it, Xia Yun decided to call his flying sword "Cicada Wing".

The method of refining the flying sword is contained in the mantra given by the master. Xia Yun followed the mantra and began to refine this cicada wing sword. Among the formulas given by the master, there are not only cultivation exercises, but also methods for sacrificing and refining magic weapons and spiritual weapons, as well as a "Bixi Sword Technique". Xia Yun didn't know if this Bixi Sword Technique was created by the master himself. After a few days of training, Xia Yun could barely control the Cicada Wing Sword, so he began to practice the Bixi Sword Technique. Since the two senior sisters and Lin Ling both learned the same sword skills, Xia Yun often practiced with senior sisters and sisters.

One day, Xia Yun, under the guidance of the senior sister, was practicing the flying of the imperial sword. At first, Xia Yun always fell from the flying sword, but after two days, despite the crooked flight, Xia Yun was finally able to stand firm on the flying sword. Slowly, as he became familiar with the control of the flying sword, his flight speed became faster and faster. When Xia Yun flew back more than twenty miles along the Bixi River with the flying sword, he saw that the master was standing in the courtyard talking with the senior sisters, so he hurriedly put away the flying sword and came to the master. After all, he had just learned to fly with the sword, and after a trip, Xia Yun had a slight bead of sweat on his forehead. Seeing Xia Yun raise his hand to wipe the beads of sweat on his forehead, Fairy Bixi praised:

"Yun'er is making rapid progress, and in a few days, she will be able to basically master the flight of Edgeworth. By the way, it seems that the master forgot the name of the sword that day. ”

"Master, the disciple gave the flying sword a name, called 'Cicada Wing Sword'."

"Cicada Wing Sword, yes, it's more appropriate than the original name, then it's called Cicada Wing Sword."

After the master finished speaking, he turned around and was about to go back to his room. didn't want to go to the door, stopped again, turned to look at Xia Yun and said:

"You should also practice the Bixi Sword Technique diligently, the four of you senior sisters must practice often, so that the progress will be faster."

"Yes, Master."

The four sisters bowed down at the same time in agreement.

In this way, in the sparring between Xia Yun and his senior sisters, as well as in the cultivation at night, day by day. After entering the summer, that is, Xia Yun came to Bixi Valley for a whole year, Xia Yun had advanced to the fourth layer in the middle of the Qi Refining Period. Xia Yun has always remembered what his master Bixi Fairy said to communicate with the flying sword from time to time, whether it is day or night, Xia Yun always keeps the sword by his side. Even when he occasionally sleeps, Xia Yun will also put the cicada wing sword on the side of his body.

As a result of this persistence, Summer is more comfortable with the cicada wing sword. Whether it is Bixi Sword Technique or Flying Edgeworth, Xia Yun is now doing a decent job. However, Xia Yun never left Bixi Valley fifty miles away. Although, since Xia Yun apprenticed, he had not heard the master announce any rules for the master, and when he asked the senior sister and Lin Ling, they also said that the master had no rules. However, Xia Yun still kept telling himself in his heart that he must not leave without the consent of his master.

Over the past year, Xia Yun has found that Master Bixi Fairy rarely walks out of the room. Occasionally came out once or twice, mostly to check the homework of the four of them. For example, the progress of cultivation, the practice of Bixi Sword Technique, and so on.

After nightfall on June 16, the moon rose round and bright, illuminating the Bixi Valley as if it were day. The four sisters had no intention of cultivating for a while, so they sat together at the stone table on the side of the courtyard near the Bixi River, chatting and admiring the moon.

"You're all here?"

Hearing Master's voice behind them, the four of them got up at the same time and asked Master to sit down at the stone table before sitting back on their seats.

"It is said that the moon is round on the fifteenth and sixteenth, did you see it today?"

"Yes, Master, why do you say that the moon is sixteen round on the fifteenth?"

Lin Ling's question made the master and the three senior sisters laugh, although they understood that Lin Ling's original intention was to ask: Why is the moon of sixteen rounder than fifteen. Xia Yun still deliberately teased her and said:

"Sister Ling'er, didn't you see that the moon tonight is indeed rounder than yesterday?"

Because of Lin Ling's well-behaved and cute, Xia Yun usually likes to tease her.

"Sister Yun knows that Ling'er didn't mean what she asked?"

"And what do you mean by asking?"

Song Chun also interjected, only Wei Xiaoxia looked at them with a smile and didn't say anything.

"Ignore you, I'm asking Master."

"Hehe, Ling'er has to work hard to cultivate, and one day when you go to the moon to see it in person, you will understand."

"Master, can I really go to the moon?"

"Why not? As long as you work hard to cultivate, it won't be long before you can go to the moon and see it. ”

Seeing that the four disciples were all looking at him with enthusiastic eyes, Fairy Bixi smiled and continued:

"Take advantage of today's opportunity to announce the rules of the teacher as well."

This made Song Chun, who was the earliest beginner, a little surprised, for so many years, the master has not announced any rules of the master, why did he think of announcing the rules of the master today. Song Chun looked at Fairy Bixi with some confusion.

"You don't have to wonder why you haven't announced the rules of the teacher, the four of you sisters are all orphans taken in by the teacher, so it can be said that the teacher watched you grow up. I know your temperament very well, and besides, you have never left Master, so there is no need to talk about any rules and regulations under Master's nose. ”

Hearing Master Bixi Fairy say this, the four of them vaguely guessed that Master might have some plans tonight.

"Our Bixi Valley is not a regular sect in the cultivation world, but since the master has accepted the four of you, you will also accept disciples in the future, so since then, Bixi Valley will slowly grow, so we have to set up some rules in advance."

The four of them silently listened to Fairy Bixi continue to speak.

"Tonight, I will announce two things for the teacher, one is that as a disciple of Bixi Valley, you are not allowed to deceive the teacher and destroy the ancestors. First, it is forbidden to kill each other. If they violate, they will be expelled from the division by abolishing their martial arts, or beheaded on the spot. ”

After speaking, Fairy Bixi looked at the four disciples in front of him one by one, and finally asked solemnly:

"Song Chun, Wei Xiaoxia, Xia Yun, Lin Ling, have you all remembered?"

"Master, the disciple remembers, don't deceive the teacher and destroy the ancestors, and don't kill each other."
