Wei WuXian suddenly murmured, “…Lan Zhan.”

He reached out and grabbed one of Lan Wangji's sleeves. Lan Wangji, who had been guarding beside him, immediately leaned over and whispered, "I'm here."

Wei WuXian was not awake yet, his eyes were still tightly closed, but his hands were still holding onto him, as if he was dreaming, he muttered: "...you...you don't be angry..."

Lan Wangji was slightly startled, and said softly, "I'm not angry."

Wei WuXian said: “…Oh.”

Hearing this, he seemed relieved and loosened his fingers.

Lan Wangji sat beside Wei Wuxian for a while, and when he saw that he was motionless again, he was about to get up, but Wei Wuxian suddenly grabbed him with his other hand, holding one of his arms tightly, and shouted, "I'm going with you, take me back to your home!"

Lan Wangji’s eyes widened.

After shouting this, Wei WuXian seemed to have woken himself up. His long eyelashes trembled and he slowly opened his eyes. His pupils went from being hazy to clear and he suddenly realized that he was holding Lan WangJi in his hands like a life-saving straw or a piece of floating wood in the water.

He immediately pulled his hand away, almost rolling over, but the movement was too big, causing the wound on his abdomen to move. He frowned with a cry of "Ah", and then he remembered that he was still injured. In the midst of the golden stars in front of his eyes, Jin Ling, Jiang Cheng, Jiang Yanli, Jiang Fengmian, Madam Yu... many faces took turns to revolve in front of him. Lan Wangji held him down and asked, "Abdomen wound?"

Wei WuXian said: “Injured? It’s okay, it doesn’t hurt…”

Lan Wangji held him down and lifted his clothes. His abdomen had been bandaged properly. He then peeled off the bandage and saw that the wound had healed. He then looked at his legs and the curse marks had also disappeared.

Wei WuXian asked, “How long have I been lying there?”

After confirming that his injuries were indeed fine, Lan Wangji let him go and said, "Four days."

Jin Ling's sword hit him right in the face, leaving a deep wound. It took four days for the wound to heal without leaving a scar, thanks to the Gusu Lan Clan's top-grade elixir. Wei Wuxian thanked him and mocked himself: "I've become so fragile after living a new life. I can't even stand a sword attack."

Lan Wangji said calmly, “No one can withstand being stabbed by a sword.”

Wei WuXian said: “That’s not necessarily true. If I were in my previous life’s body, I could stuff my intestines back on their own and fight another 300 battles.”

Seeing that he had just woken up and started talking nonsense again, Lan Wangji shook his head and turned away. Wei Wuxian thought he was going to leave, so he hurriedly said, "Lan Zhan, Lan Zhan! Don't go. I'm talking nonsense, I'm not good, please don't ignore me."

Lan Wangji asked, "Are you still afraid that people will ignore you?"

Wei WuXian said, “I’m afraid. I’m afraid.”

It had been a long time since he had experienced the feeling of having someone by his side after waking up from an injury.

Lan Wangji had two swords on his waist. He took one out casually and handed it to him: "Your sword."

When Wei WuXian saw the sword, he was stunned for a moment before he said, “Thank you.”

He gripped the hilt of the sword and gently pulled it out. A pair of eyes appeared on the sharp edge of the sword. Wei Wuxian stared at the eyes for a while, then put the sword back into the sheath and asked, "Did it really seal itself automatically?"

Lan Wangji also grabbed the hilt of the sword and pulled it out, but it didn't move. Wei Wuxian sighed, patted the sword, and thought to himself, "I knew Jin Guangyao wouldn't dare to make up a story... He actually sealed the sword. I actually ran into a once-in-a-million-time good thing. Now, the evidence is irrefutable. The person who pulled it out must be Wei Wuxian, and he can't deny it."

Looking around, it was a clean and simple room with dim lighting, except for a paper lantern in the corner. Wei WuXian asked, "Where is this?"

Lan Wangji said, "The cloud is so deep that I don't know where it is."

Wei Wuxian said, "You're taking me back to the Cloud Recesses? What if your elder brother finds out?"

One person said: "I have found it."

A man came in from behind the screen. He was wearing a white robe and had a headband. His face was as beautiful as jade and his expression was solemn.

After four days of recuperation at the Cloud Recesses, Lan Xichen had not been captured by the Lanling Jin Clan. He thought that Lan Xichen should not be a threat. In addition, Lan Wangji was right beside him, so Wei Wuxian was not on guard. He suddenly remembered something and asked, "Where is Chi Fengzun's body?"

Lan Xichen said, “Everyone has seen my elder brother’s body with their own eyes. It is currently in the care of Huaisang, and I have also sent someone I can trust to look after it.”

Wei WuXian felt slightly relieved and asked, “What was Jin GuangYao’s reaction?”

Lan Wangji said, “It’s flawless.”

Wei Wuxian knew that Jin Guangyao would definitely make a big show to make sure that he couldn't destroy the body. Unexpectedly, Lan Xichen said slowly: "He said that he would give an explanation after getting to the bottom of this matter. And since Master Wei has woken up, then, Wangji, you should also give me an explanation."

Lan Wangji stood up and said, "Brother."

Lan Xichen sighed and said, "Wangji, what can I say about you?"

Lan Wangji said, “Brother, Chi Fengzun’s head is indeed in Jin Guangyao’s hands.”

Lan Xichen asked, “Did you see it with your own eyes?”

Lan Wangji said, “He saw it with his own eyes.”

Lan Xichen asked: "Do you believe him?"

Lan Wangji said, “I believe it.”

He answered without hesitation, and Wei Wuxian felt a warm sensation in his chest. Lan Xichen asked, “What about Jin Guangyao?”

Lan Wangji said, “It’s unbelievable.”

Lan Xichen smiled and said, “Wangji, how do you judge whether a person is trustworthy or not?”

He looked at Wei Wuxian and said, "You believe in Master Wei, but I believe in Jin Guangyao. Big brother's head is in his hand. We didn't witness this incident with our own eyes. We all believed what the other person said based on our own understanding of him.

"You think you understand Wei Wuxian, so you trust him; and I think I understand Jin Guangyao, so I trust him too. You trust your own judgment, so can't I trust my own judgment?"

Wei WuXian was afraid that the two brothers would start arguing over this, so he said, “Sect Master Lan!”

It’s not that he can’t understand Lan Xichen. He sees Jin Guangyao from Nie Mingjue’s perspective, and sees his cunning and ambition. However, if Jin Guangyao has been pretending to be in front of Lan Xichen for many years, there is no reason for him not to trust his sworn brother and trust a notorious person instead.

Lan Xichen nodded and said, "Master Wei, you don't have to worry. Before the truth comes out, I will not trust any side, nor will I expose your whereabouts. Otherwise, I would not have asked Wangji to send you to my cold room and heal your injuries."

Wei WuXian said, “Thank you, Sect Master Lan, for giving me this opportunity. The head of Chi Feng Zun is in Jin Guangyao’s secret room. It is absolutely true. Not only did I see it, but I was also infected by his resentment and saw some things. I wonder if this can be considered as proof?”

Lan Xichen said calmly: "Master Wei, maybe you did see something, but you can't prove that you saw it in the secret room in Jinlingtai."

Wei WuXian said, “Well, that’s true. Let me talk about something else. The direct cause of Chi Feng Zun’s death was indeed his infatuation, but Sect Master Lan, don’t you think the timing is too coincidental? The sword spirit’s mischief is one of the reasons, but have you ever thought that there are other reasons behind it?”

Lan Xichen asked, “What do you think the trigger was?”

Wei WuXian said, “Mysterious Song of the Pure Heart.”

Lan Xichen said, “Master Wei, you know that the Qingxin Xuanyin he played was taught to him by me personally.”

Wei WuXian said, “Then please listen to this piece of music, Sect Master Lan. Is there anything strange about it?”

His flute was placed beside the bed, Wei Wuxian picked it up, lowered his head and thought for a moment, then began to play. After the song was over, he asked, "Master Lan, is this song really the one you taught Jin Guangyao?"

Lan Xichen said, “That’s right.”

Wei WuXian was slightly surprised, but he calmed down and asked, "What's the name of this song?"

Lan Xichen said, “This song is called ‘Xi Hua’ and it has the effect of clearing the mind and calming the spirit.”

Wei WuXian said, “Xihua. I have heard many famous Xuanmen songs, so why do I have no impression of its name and melody?”

Lan Wangji said, “This song is obscure and difficult to learn.”

Lan Xichen said, “That’s right.”

Wei WuXian asked, “Did Jin GuangYao specifically ask us to learn this song?”

Lan Xichen said, “Not bad.”

Wei WuXian asked, “Is it really that difficult to learn? Then why did Jin GuangYao specifically choose this piece of music instead of other easier ones?”

Lan Xichen said, “Because I told him that although Xihua is difficult to learn, it is very effective. This piece of music is indeed tricky. Didn’t Young Master Wei make a mistake just now?”

Hearing this, Wei WuXian's heart moved, and he asked, "Did I blow the wrong tune just now?"

Lan Wangji said, “There’s a paragraph in the middle that’s wrong.”

Wei WuXian smiled and said, “No, no. It’s not me who is wrong. It’s Jin GuangYao who is wrong! When the resentment invaded, he played exactly like this. I can guarantee that I repeated this piece of music word for word correctly.”

Lan Xichen was surprised and said, “So he learned it wrong? This... is impossible.”

Wei WuXian said, “It is indeed impossible. How could Lian Fang Zun, who is so smart and has an excellent memory, remember the wrong tune? I am afraid it is probably intentional. I will play it again, Sect Master Lan, Han Guang-Jun, please listen carefully to the part where it is played wrong this time.”

He really played it again, and when he was about to finish the second paragraph, Lan Wangji said, “Stop.”

Lan Xichen said, “It’s this paragraph just now.”

Wei WuXian took the flute from his lips and said, “Is this really the part? But I think this part doesn’t sound out of place.”

Lan Xichen said: “It is indeed not inconsistent. However, it is definitely not part of “Washing Hua”.”

If it was just a common mistake in playing, it would not blend so seamlessly with the rest of the original song. This melody must have been deliberately polished and inserted. This strange melody that did not belong to "Washing Hua" but was mixed into "Washing Hua" was very likely the key to Nie Mingjue's death.

After thinking for a moment, Lan Xichen said, "Come with me."

After leaving the house, Wei WuXian was slightly startled.

This is a secluded little building, somewhere hidden in the clouds. The Lan family's immortal residence is located in the deep mountains. There are pine trees and trees in the area, mostly green trees and orchids. It is not that there are no flowers, but they are all fresh and elegant varieties such as magnolia, gardenia, and white chrysanthemum, and they are only used as sporadic embellishments for a glimpse. In front of this house, there are purple gentians. The flowers are petite, the colors are gorgeous, and they are lovable. In the night, they seem to emit a faint fluorescence, beautiful as a dream.

Wei Wuxian felt that there must be something strange about this place, but he only had time to take a quick glance and had no time to investigate. It was past midnight, and most people in the Cloud Recesses had already gone to bed. It was extremely quiet, and there was no one along the way. Lan Xichen took them directly to  the library .

The Cloud Recesses had been burned by a fire, and  the library was no longer the same as it was back then, but after the reconstruction, it was exactly the same as the original layout, and even the magnolia tree outside the pavilion was replanted. The three of them entered the pavilion, and Wei Wuxian asked doubtfully, "Master Lan, can we find the source of this melody here?"

Lan Xichen said, “Not here.”

He walked to a row of  bookcases , squatted down, lifted a mat spread there, uncovered the wooden board underneath, and said, "This is fine."

Under the wooden board is a secret door.

Lan Wangji said, "The forbidden  study room."

Under the secret door was a staircase with more than 50 steps. The three of them went down the staircase one by one, and what appeared in front of Wei Wuxian was a dry and spacious underground stone chamber. The sound of their footsteps echoed in the basement. There were rows of bookcases in the forbidden  study room, and books were sparsely classified on the shelves. They were covered with dust, and it seemed that no one had flipped through them for many years.

Lan Xichen led them to a row of  bookcases and said, “This one contains all the strange records.”

There was a desk in the forbidden book room, and there was only a paper lantern on the desk. Lan Wangji took the paper and pen that had been on the shelf for years and wrote down three copies of the music score of that melody. The three of them sat around the  desk and divided the work, each of them was responsible for dozens of books, one by one, page by page, comparing the music scores copied and listed in the forbidden book, looking for the parts that matched them.

However, after two hours, none of the three people found a piece of music that matched that melody. In other words, they did not find its source.

As Wei WuXian read through the score at a glance, he thought to himself, “Could it be that the Lan family  ’s Forbidden  Book Room’s Book Collection Pavilion doesn’t include this piece of music? Impossible. If even the Lan family doesn’t have it, it’s impossible for other places to have it. It’s impossible that Jin GuangYao created a divine song himself? That would be troublesome. To prove that there’s something fishy about this song, we have to find someone to listen to it for a few months to test it. But although he’s smart, he’s only a latecomer after all. He’s not smart enough to create something on his own…”

Wei Wuxian spent a long time reading these densely packed small characters, and felt dizzy. He still had a few books left, so he decided to put them aside for a while before reading them again. Lan Wangji had already finished reading his stack, and silently took the books that Wei Wuxian had left behind, lowering his head to continue searching. Lan Xichen slowly raised his eyes, and when he saw this, he was about to say something but stopped.

At this moment, Lan Wangji said, "This one."

He handed the  book over, and Wei WuXian perked up immediately. He carefully looked at the two pages he had opened, and compared them with the incomplete score in his hand, and said, “Completely different?”

Lan Wangji stood up, sat next to him, and pointed to him: "Look at the two pages before and after."

Their heads were close together, Lan Wangji's voice was right beside his ear, low and magnetic, Wei Wuxian's hand trembled slightly, and  the book almost fell. It was hard for him to calm down, forcing himself to move his eyes away from Lan Wangji's slender white fingers, carefully distinguishing, and said: "Ah, the front and back two pages."

At first glance, there seems to be nothing wrong with this music album, but if someone who is familiar with music pays more attention, they can see that the music on the previous page does not connect with the music on the next page.
