"Are you sure it's exactly the same?"

Yan Huailiu asked in disbelief.

"I guarantee it with my life." Gu Xingyun was very confident in himself and handed the paper over.

Yan Huailiu glanced at him and said, "There's no need to make it so serious."

He carefully placed the picture drawn by Gu Xingyun on top of the Yin-Yang Reincarnation Formation.

Since this is located at the center of the formation, there must be some place that can be connected together.

When he concentrates on studying something, he is always extremely focused, his expression will unconsciously become serious, and his brows will be slightly furrowed throughout the process.

Gu Xingyun did not make a sound to interrupt him, but just sat there, supporting his chin with one hand and staring at him quietly the whole time.

"Hmm... Let me think about it. Since there's an overlap in the center of the array's core, does that mean the Yin-Yang Samsara Array can be used as an extension of it?"

"That seems correct, so we should follow this route? And then follow it backwards?"

"Isn't that right?"

Gu Xingyun thought he was talking to him, so he leaned over to take a look and replied, "It seems so."

But Yan Huailiu ignored him at all. Instead, he changed the color of ink and slowly marked along the direction of the formation.

Continue explaining it to yourself.

"Assuming it follows these paths, then under this premise, if we want to run two formations simultaneously, we should do this..."

Gu Xingyun shook his head helplessly.

It seems that until this formation diagram is developed, he can forget about making his presence felt.

Fortunately, when Yan Huailiu talked to himself, what he said was extremely detailed.

Gu Xingyun was quickly attracted to it and took a pen and paper to take notes.

Inside the Xuanyue Palace, a group of people huddled in a cave, not even having time to eat, and were working desperately on their research.

Palace Master Murong even dug out all the relevant information about Xuanyue Palace over the past hundred years.

Feeling that there were not enough people, he sent people to call back the disciples who had already been sent away.

The sky became completely dark.

Yan Huailiu moved closer and closer to the table, and finally almost lay on the table to look at the pictures.

A hand covered his eyes and gently lifted his head upwards.

"Master, it's late. There's no need to rush. Let's wait and see tomorrow."

"Hmm?" Yan Huailiu looked a little confused, as if he had just discovered that there was someone sitting next to him.

After hesitating for a few seconds, he suddenly woke up and turned his head to look at the sky outside: "It's so late! If you are tired, why don't you rest first?"

Gu Xingyun took the pen from his hand, and then patiently massaged his hands.

"I want to wait for Master to rest together."

"Write it tomorrow. It's too late."

Yan Huailiu said "oh" and obeyed obediently.

The originally stiff hand gradually got better under Gu Xingyun's massage. Just as Yan Huailiu was about to thank him, he saw Gu Xingyun stand up and walk behind him.

The same force was felt in my shoulders and neck, and suddenly I felt an indescribable emotion.

Many details that he himself did not care about were always discovered and taken seriously by Gu Xingyun.

He always felt that he was a person who was difficult to be moved, but Gu Xingyun could always easily grasp his heart in various small things.

"It doesn't hurt that much..."

He muttered something under his breath.

"Master has been keeping his head down. He will feel uncomfortable if he doesn't press it twice. The medicine to relieve this discomfort is quite bitter, and Master doesn't want to drink it, so we can only use this stupid method."

Yan Huailiu pursed his lips, clenched his clothes with his hands on his knees, and said nothing.

"When Master is busy, he always neglects me and doesn't listen to what others are saying."

Gu Xingyun's fingers slid gently along his neck, helping him to relax the stiff muscles.

Feeling the touch under his hand, he couldn't help but frown.

Is it an illusion?

Master seems to have lost weight again.

"Master, even if you have to be busy, you must take care of your own health first. If your disciple is no longer around in the future, who would dare to remind you to rest in the middle of the night?"

He said it very casually.

Yan Huailiu felt a little ashamed to be lectured by someone so much younger than him.

"That's not an exaggeration. I'm not a porcelain doll."

When he was busy, he could stay up all night for several days in a row. At that time, it seemed...

Never mind, it seemed pretty uncomfortable at that time.

Gu Xingyun paused for a moment, as if to sigh, and pinched a few more times before withdrawing his hand.

"Master, go to sleep."

After he said this, he prepared to go out.

Yan Huailiu grabbed his hand and asked, "Where are you going?"

"Master, do you want me to stay?" Gu Xingyun asked deliberately and bluntly.

And prepared to continue going out.

But Yan Huailiu was very firm at this moment: "Yes, the bed here is very wide and can sleep two people."

He was worried about his apprentice leaving his sight.

This is not the Yuxu Sect. If Gu Xingyun's situation is seen by outsiders, it will be very troublesome.

"Didn't Master say that we can't do anything stupid outside?" Gu Xingyun said with a smile.

Yan Huailiu's eyes flickered, and his voice weakened: "You speak as if you have never heard of anything before."

He had told Gu Xingyun so many times not to do this kind of thing, but didn't he still do what he wanted?

"I'll go get a pillow from next door, you wait here."

Yan Huailiu forced him to sit on the bed and walked out quickly.

There was an obvious smile on Gu Xingyun's face, but it disappeared in just a moment.

He quickly took out the small pink bottle and drank a drop, fearing that the thing would suddenly lose its effect.

If I can go back, I will ask Jingming to study it and see if I can make a few more bottles.

If not, he can only find a way to exchange it with Fei Miao for something else.

The moonlight of Xuanyue Palace could not compare to that of their Yuxu Sect after all. Gu Xingyun took a look and then looked away, staring at his hands.

It’s not that he didn’t want to stay, but he was afraid that the evil energy in his body would suddenly erupt and hurt Yan Huailiu.

Before Yan Huailiu came in, he tapped his vital points twice with his fingers, sealing his cultivation.

"It feels like the house next door has never been lived in. This one looks dirty and a bit hard."

Yan Huailiu walked in holding a corner of the pillow.

Gu Xingyun reached out and took it: "Master, it's not dirty, it's just that the material is a little old, and it may have been filled with too much buckwheat. I am used to using this kind, it's fine."

He has always been easy to feed and is not picky about anything.

Yan Huailiu reached out and patted the pillow, making sure that no dust had come up before he felt relieved.

From the moment he lay down, Yan Huailiu felt uncomfortable.

It's not just the bed.

"Why don't you just sleep on the floor?" He was so angry that he gritted his teeth and started to speak in a sarcastic tone for the first time.

"Is this a place reserved for Little Lightning to have fun?"

"You're quite generous. You've even started rehearsing in advance."

"With such a wide distance, not only can it roam freely, but it can also host a buffet for its wedding."

The room was quiet for a long time before a sigh was heard.

The next second, Gu Xingyun moved back from the bed, almost compressing the distance between them to the extreme.

It's only a fingernail's distance away from touching it.

"Master, I'm just afraid of hurting you."
