Feiyun Zhou, this is the first magic weapon given to Zhang Fan by Han Hao back then, so it has been treasured by him to this day.

This magic weapon also has its own special features, although it was refined by Han Hao himself, the effect when it succeeded was beyond his expectations, and the reason was the material it used.

It was an unknown demon beast bone, and it was this bone as the main material that made Feiyunzhou, a high-level magic weapon refined by ordinary refining techniques, have a higher speed than most flying spirit weapons.

Han Hao and Zhang Fan were both very interested in refining weapons, and they had naturally studied this in depth, but no matter how they searched for information and searched through the classics of their predecessors, they had never found the slightest trace of this beast bone.

After so many years, Zhang Fan had forgotten about it, and the reason why he still had the Feiyun Boat was just a little nostalgia for his master Han Hao.

No, now without any psychological preparation, a similar material appeared in front of him again.

The bone flute left by this uncle Wuji, strictly speaking, is not the same as the main material of Feiyun Boat, one is helpful for speed, and the other is obviously conducive to sound wave transmission, if ordinary people see it, I am afraid that it is normal to think that the two have nothing to do with each other.

Zhang Fan doesn't see it that way, people who are proficient in refining weapons must also be proficient in distinguishing materials, this is a one-and-two-two-one thing, with his eyesight that has been trained for many years, the beast bones that make up these two things may not be from the same kind of demon beast, but they are definitely from the same place. "How did Master get this beast bone, and what is the connection?"

Zhang Fan's brows were furrowed, but he had no clue to speak of.

This unique beast bone should be a remnant unique to a demon beast born in a special environment, otherwise it would never be so ingenious.

The moment Zhang Fan started the bone flute, he used the "Great Five Elements Forbidden Breaking Technique", and the conclusion he reached was in line with his guess.

The refining technique of this bone flute is a special method that is very different from the current immortal cultivation world and quite mature, and it is specially refined by mixing bone materials with metal materials.

Although there are also demon beast bones refining magic weapons in the immortal cultivation world, it is definitely not as mature and perfect as this technique embodied in this bone flute, if it were not for a large number of various beast bones with useful value to be used, such a technique would definitely not have been developed.

Thinking of this, Zhang Fan couldn't help but think of that picture scroll, the place painted on it, is it where these animal bones are produced?

"Brother, do you want to listen to Wan'er play the flute?"

Seeing Zhang Fan looking at the bone flute, Wan'er suddenly spoke.

Looking at Wan'er's slightly expectant and apprehensive eyes, Zhang Fan smiled slightly, handed her the bone flute, and asked, "Do you know how to blow it?"

In addition to being a rare spiritual weapon, this bone flute is also a good musical instrument, looking at Wan'er's appearance, I am afraid that Shu Wuji used it the same way, otherwise in this closed space, who can teach her?

No, as soon as Zhang Fan's words fell, Wan'er answered, but what she said was very different from what he imagined.

"It can blow! Wan'er learned by looking at it herself. ”

Wan'er raised her head proudly and took the bone flute.

"Well, you learned it?"

"yes!"

"My dad used to sit here and play the flute. ”

Wan'er walked to her mother's grave, sat down cross-legged, and at the same time stretched out her little hand to caress the tombstone, and the word "Yunshui" was exactly where she landed.

"Daddy is just touching and blowing like this, and sitting all day long!"

Wan'er asked him to teach him and he refused, Wan'er watched and learned. ”

When Wan'er said this, she turned around and smiled at Zhang Fan, slowly put the bone flute on the cherry blossom mouth, and tried the sound, and then, a faint sad tune echoed in the air.

Wan'er's amazing voice seems to have also acted on the bone flute, and the beautiful timbre bulges out of the cheeks with the press in her hand, and keeps overflowing from the bone flute, and then overflowing, as well as endless sadness, makes people listen to a sudden chill in their hearts, and the scene that they don't want to recall in their lives irrepressibly reappears in their minds.

In the mournful sound of the flute, as if time and space were out of order, the person sitting upright before the tombstone was no longer a lovely girl, but a clear middle-aged man, caressing his wife's tombstone with one hand, and playing the flute with the other...... Listening to this flute, Zhang Fan couldn't help but sigh secretly.

Wan'er is indeed as she said, she has not really learned to play, although she blows very emotionally, but it is all other people's feelings, and even on her slightly immature face, the deep nostalgia and sorrow that vaguely emerges are all the shadows of another person, and even the expression is reproducing the past invisibly.

When the two of them blew and listened, they couldn't help but be immersed in some kind of emotion, and they were in a trance for a while.

At this moment, a soft chirp like a bee flapping its wings sounded, interrupting the thoughts of both of them together.

Zhang Fan frowned slightly, flipped his hand, and a jade talisman like a fresh green leaf appeared in his hand.

- "The Jade Talisman of Sound Transmission".

It was the sound transmission jade talisman that was given to him by Wanqing before, Zhilantian's special secret transmission.

At that time, Zhang Fan suspected that the way it transmitted the message was related to plants, and now when the jade talisman vibrate, he saw that the surrounding plants also trembled slightly, as if they wanted to fly out, and his heart became more and more affirmed.

After confirming this, Zhang Fan no longer hesitated, and the spiritual power in his hand was slightly poured into the jade talisman, and a gentle voice sounded in an instant: "Brother Zhang Dao, we found something, where are you now?"

said that he had found something, but in Wanqing's voice, there was a "surprise", but it was not a surprise, but a little panicked.

Zhang Fan wondered in his heart, what was there in this Shutong Cave Mansion that was worth the two of them to panic about? Then he said, "I also have some discoveries here, come and talk about it!"

As he spoke, he reported the location of the village and waited for the two of them to arrive.

After putting away the jade talisman, he found that Wan'er was looking at him timidly, looking like she wanted to say something.

Smiling slightly, Zhang Fan asked, "Wan'er, what's wrong?"

"Brother!" Wan'er walked to his side, lowered her head and rubbed the corners of her clothes, "Wait, is there anyone else coming?"

"Does Wan'er have to call her brother and sister?"

"Huh?" Zhang Fan raised his eyebrows, he felt very strange when he called his brother before, but now it seems that this title still has the meaning of expansion, and he couldn't help but wonder: "Why do you call it that?"

"Daddy taught me!"

Wan'er pointed to the wooden tombstone with a pout, and then added: "At that time, while vomiting blood, my father called Wan'er to the bed and said, if there are outsiders in the future, if it is a man, it will be called brother, and if it is a woman, it will be called sister, and if it is old, it will be called master, and Mrs. ......."

Zhang Fan originally looked at Wan'er's puffed up appearance and smiled, but when he heard it, the smile gradually disappeared and was replaced by a heavy color.

It can be seen from the level of the bone flute and the scene on the picture scroll that this uncle Wuji is at least an immortal cultivator in the foundation building period, but before he died, he had to explain to his daughter like this, hoping that when he met other immortal cultivators in the future, he would save his life and be taken out of this cage by the other party.

A few words of faint advice, there is a strong sense of sadness inside, Wan'er and they don't know it, but Shu Wuji clearly knows that their world is just a cage, or a cage that is about to be destroyed, how to make him not anxious.

Secretly sighing, Zhang Fan raised his hand to stop Wan'er's words.

Wan'er choked for a moment, glanced at his expression cautiously, and whispered, "Brother, is it okay for Wan'er to call you only one brother?"

"I don't like to call people that. ”

"Brother, do you like Wan'er to be called that?"

After asking a few questions one after another, Zhang Fan's face slowly brought a little smile, and comforted her: "I like it very much, so be it." ”

The two of them only took a few words, and two streamers, one red and one green, instantly crossed the sky, bringing up countless purple rhyme debris and quickly flashed in front of Zhang Fan and Wan'er.

"Ahh

Wan'er was startled when she saw this, and in a flash, she hid behind Zhang Fan's back, as if his broad shoulders gave her a sense of security, and then quickly poked her head out from behind her shoulders and looked at the two of them curiously.

Wanqing and a glass of wine just glanced at her slightly, and then stopped paying attention, the two walked up to Zhang Fan, and didn't say anything, Wanqing quickly took out a jade box and handed it over, and said solemnly: "Brother Dao, look at this thing." ”

"Huh?"

This jade box should contain spiritual grass, could it be that they found the spiritual grass that still remains in the Shutong Cave Mansion? But so what, there is no need to be so solemn!

Zhang Fan knew that if he really found some rare spirit grass, with the relationship between the three of them being unacquainted, the two of them would definitely not tell him about it, then there must be something else mysterious in front of him.

took the jade box, opened it carefully, and glanced inside, Zhang Fan's face suddenly showed a stunned look.

"It's ......"

"Huang Jing?"

Yellow essence, a very ordinary one-taste spirit grass, is also sold in mortal pharmacies, and it is not too much to describe it as being all over the mountains.

However, if Huang Jing is a year, it can also refine some pills used by immortal cultivators, such as the one in front of him, that is, Zhang Fan does not have much research on the year of the spirit grass, and it can be seen that at least more than seven or eight hundred years, it can roughly refine some pills used in the foundation building period.

Among the spirit herbs that Zhang Fan had previously purchased in Zhilantian to refine the Yunling Pill, there was no shortage of yellow essence of such a year.

This elixir, if there is any difference from other elixirs, is that the vitality is particularly tenacious, it is similar to wild grasses, not as delicate as most elixirs, and has many requirements for the living environment.

It is estimated that this is also the reason why the yellow essence in front of me has survived until now!

"But ......"

After watching for a long time, Zhang Fan didn't see anything abnormal, and couldn't help but look up at Wanqing.

Seeing his doubts, Wanqing's face was still solemn, and she said in a deep voice: "Fellow Daoist, please look at its leaves, do you have some familiarity?"
