In front of the counter, Mu Xiyun assembled, spliced, and tested the parts in front of him one by one, and finally successfully made three "needle crossbows".

There are also a large number of special silver needles in the ring, the Star Needle.

Obviously, the Silver Needle is made from the Star Gold Mine, which is a waste of resources, but its power can be maximized, after all, the Star Gold Mine has a great bonus to toughness and penetration.

The next day, early in the morning...

Mu Xiyun's eyes opened, he woke up from his cultivation, exhaled lightly, and then went out and walked towards Mu Xin'er's room.

"Knock knock..."

"Brother, you're here!" As soon as she opened the door, she saw Mu Xiyun, and Mu Xin'er's hazy sleepy eyes suddenly woke up.

"Follow me!" Mu Xiyun directly grabbed Mu Xin'er and walked towards the back mountain.

Mountaintop...

Surrounded by clouds and mist, ethereal like a fairyland, the two sat quietly on a big stone, snuggled up to each other, a gust of breeze blew in their faces, lifting the hair on their foreheads, quiet, elegant, comfortable...

After a long time, the east gradually brightened, and a touch of fish belly white gradually appeared in front of the two of them.

"Brother, why do you want to take me to see the sunrise?" Mu Xin'er propped her hands on the stone, looked at Mu Xiyun with her head bowed, and her eyes were full of softness.

"Because... I think..."Mu Xiyun looked at Mu Xin'er with a smile on her face.

"What are you looking at?" Mu Xiyun kept staring at, and Mu Xin'er looked puzzled.

The corners of Mu Xiyun's mouth were slightly hooked, and she looked at Mu Xin'er with a smile on her face, and said, "In the future, I don't want to call you 'sister'!"

"What do you call me?" Mu Xin'er raised her head slightly, looking puzzled.

"Of course I call you 'Xin'er'!" Mu Xiyun smiled even more on his face, and said with a smile.

"???" Mu Xin'er was stunned for a moment, then her mouth was pursed high, and she said with a natural expression: "I'm older than you, I'm your sister, you have to call it that!"

"Xin'er, what did you say? I didn't hear clearly!" Mu Xiyun's small face was tightened, and her ears were a little closer.

"I said you want to call me 'sister', you can't call me 'Xin'er!" Mu Xin'er said unhappily.

"Well, okay, I'll listen to Xin'er!" Mu Xiyun nodded very obediently.

Seeing this, Mu Xin'er smiled with satisfaction, but soon realized something and grabbed Mu Xiyun.

"Ahh Xin'er... Why are you pinching me!" Mu Xiyun hurriedly covered his small waist, showing grievances.

Mu Xin'er nudged Mu Xiyun, and said coquettishly: "Don't say it, don't call your sister, you want to call Xin'er... Oh no, you are not allowed to call Xin'er, you must be called ......."

Without waiting for Mu Xin'er to finish speaking, Mu Xiyun was excited, and said seriously as quickly as possible: "Yes, obey the order, never call my sister again in the future, call Xin'er!"

Mu Xin'er stomped her feet, a little dissatisfied, and wanted to continue, but Mu Xiyun directly pulled her up and came to a tree.

"Look at this!" Mu Xiyun took out a box and poured the aura of ten spirit stones into the groove in the middle.

"Click!" the box gradually loosened, and various gears turned, and then a pair of thin light wings formed on both sides, with a small head sticking out in front and a long red tail in the back, and the whole thing looked like a bird.

"This is called 'Sound Sparrow', give it to you!" Mu Xiyun opened his hand, and his hand was no longer a box, but a lifelike sound sparrow.

The wings of the Transmission Sparrow stirred and slowly flew up, and it was not the wings that made it fly, but the energy of the ten spirit stones.

The sound transmission finch circled Mu Xin'er and stood on her shoulder.

Mu Xin'er tilted her head, her lips were slightly upturned, and her beautiful eyes were full of joy.

"Here you go!" Mu Xiyun took out two boxes again, and said with a smile: "These three sound sparrows, you can use them as toys when you are usually bored, if you want to find me, it will be like this..."

After speaking, Mu Xiyun waved his hands and locked his breath in the sound sparrow, and then with a hand, the sound sparrow flew again... Soon stood on Mu Xiyun's body.

...

"There's one more thing I want to give you, this one is very important!" Mu Xiyun smiled mysteriously.

"Take it!" Mu Xiyun took out a blue jade cylinder, with more than a dozen pinhole-sized holes on its head, and a line of words engraved on the barrel body, "Princess Xin'er's personal guardian artifact, don't think about demons and monsters." ”

"Poof...... Mu Xin'er took the jade tube, looked at the crooked font, and couldn't help laughing directly, and then asked, "Why give me this?"

"Of course it's for you!"

"Protect me?"

Mu Xiyun smiled slightly, with nostalgia on his face: "In the past, in Mu Mansion, there would always be many cousins and cousins who pointed fingers at me, and often talked about me behind my back as a 'disaster star', and then... They're going to be beaten up by you!"

"Hmph, who told them to bully you!" Mu Xin'er clasped her hands to her chest, looking like she took it for granted.

Seeing this scene, Mu Xiyun couldn't cry or laugh a little, and he was sad for those cousins and cousins for a second in his heart.

Mu Xiyun grinned and said with a smile: "It is because of Xin'er that I can grow up without worry!"

Mu Xin'er was stunned, stomped her feet again, and said, "Your name is still Xin'er, and you have said that you want to call..."

"Here you go, you'll give it to you, take it well, take it well..." Mu Xiyun directly stuffed the jade tube and blocked back what Mu Xin'er was going to say.

There are various patterns engraved on the jade tube, including small animals, small grasses, and small flowers.

Mu Xin'er took the jade tube, looked at the various patterns on it, her face softened, she hesitated for a moment, and said softly: "In the future... Don't scream in front of your father..."

Mu Xiyun took out a jade cylinder that was the same as Mu Xin'er's hand, but there was no fancy pattern on it, and then, Mu Xiyun restrained his smile, looked serious, and said seriously: "This is called 'needle crossbow', and there are three buttons on it." ”

"Injecting a spirit stone and pressing the first button again, a silver needle will be issued, and its power is equivalent to the attack of a Yuan Spirit Second Realm!" Mu Xiyun explained as he pointed to the needle crossbow.

"Injecting ten spirit stones, and then pressing the second button, ten silver needles will be issued, and their power is equivalent to the attack of a Yuan Spirit Nine Mirrors!" Mu Xiyun said to himself.

At this point, Mu Xin'er frowned slightly, looking at Mu Xiyun and the jade tube in his hand blankly, her expression was complicated, I don't know if it was too shocked or because of something else...

"And the last button..."Mu Xiyun took out a spirit jade, handed it to Mu Xin'er, and said with a more serious expression: "Inject a spirit jade, and then press the third button to activate!"

After speaking, Mu Xiyun paused slightly, looked up at the sky, his eyes were foggy, and after a while, he sighed and continued: "I don't want you to use the day... I don't want your pure heart to be tainted with even the slightest innocent sin..."

When the words fell, Mu Xin'er was stunned, as if she was digesting this huge amount of information, and the two didn't say a word for a long time!

After a long time, Mu Xin'er slowly turned around, walked to the big stone just now, and sat down again.

Mu Xiyun was stunned, followed directly, sat next to Mu Xin'er, and continued to watch the sunrise.

The morning sun had not yet faded, and the sky was still a hazy red, and the breeze blew past the two from time to time, responding to the silent silence.

Mu Xin'er looked at the east, not knowing what she was thinking, for a long time, she sighed: "I found that you have changed!"

"Where have I changed?" Mu Xiyun said subconsciously.

"I don't know..."

"Maybe I'm thinking too much..."

"It's because... Last night?" Mu Xiyun smiled and said with some hesitation.

"It's not just last night..."

Mu Xiyun: "..."

"I feel like you're hiding something from me!" Mu Xin'er lowered her head, looking a little sentimental.

"In the past, you wouldn't have deceived me in any way, but now... I feel like you've become mysterious... Sometimes I even suspect that you are still not my brother, and every time this idea comes up, I deny it..."

"Although you often behave like you, we have lived together for more than ten years, how can I not tell the difference..."

After a long time, Mu Xin'er raised her head and looked at Mu Xiyun, a smile appeared on her face: "Although you have changed, I can feel it... You're still that little brother of mine, and you'll never leave my brother..."

Mu Xiyun opened his mouth, wanting to say something, but he couldn't.

The two of them were still watching the sunrise, the sky was pale red, and time was slowly slipping away...

In the end, Mu Xiyun seemed to have made up his mind, and said with relief: "I do have something to hide from you, that matter is not big or small, and it is not small or small!"

"Actually... The 'master' I told you about is myself, I am the one who healed my father, and I am the one who killed Yuelian......"

Mu Xin'er was stunned again, shocked and shocked.

Seeing this, Mu Xiyun hurriedly shook his hand, and said in a panic: "You don't have to worry, I'm still the same me, but there are a lot of things I can't tell now..."

Before Mu Xiyun finished speaking, Mu Xin'er directly covered his mouth, Shaoqing, tilted his head, slightly bent his eyebrows, and showed a bright smile on his pretty face, saying, "I can feel it..."

After a long time, Mu Xin'er suddenly spoke: "If there is a past life, do you say you are an elder brother or a younger brother?"

Mu Xiyun was a little confused about Mu Xin'er's inexplicable change, but she quickly reacted and said with a smile: "Of course it's my brother, I must have let you, you have the opportunity to be a sister in this life!"
