Yun Lintian put his jumbled thoughts aside and went to the extended bookshelf on the left. He examined it for a moment and found nothing out of the ordinary before he channelled his profound energy onto it. The bookshelf trembled slightly with a creaking sound and began to move sideways, revealing a hidden door behind it.

"Tsk. This old man hiding something here all this time?" Yun Lintian clicked his tongue in amusement and opened the door, walking into it. ​​

"What the…" Yun Lintian exclaimed when he arrived in a vast room with countless towering bookshelves stand tall along with all kinds of books on them. There were at least a hundred aisles from his estimation, and each one of them was deep, around 200 meters. The floor was laid with Heavenly Sandalwood planks, emitting a soothing fragrance making ones' mind became clearer upon inhaling.

On the left side, there was a small counter and comfortable-looking chairs reserved for a librarian. Hanging on the wall was a large touchscreen monitor currently showing a sentence 'Welcome to the library' in digital text.

What surprised Yun Lintian the most was the size of the room. There was no way his villa could contain this room. Undoubtedly, this place had to be a profound artifact.

Calming himself down, Yun Lintian walked to the touchscreen monitor and touched it with his finger.

"Scanning…" Suddenly, a sweet female voice rang out from built-in speakers around the library.

"Detecting the SSS level identity."

"Identity confirm."

"Welcome Master Yun Lintian to the library."

"My name is Smart 01, the library's administrator."

"If Master has any question, please feel free to ask me."

A series of female voices resounded, causing Yun Lintian to startle for a moment. He was both surprised and overjoyed at the same time. With this A.I., he didn't have to check all the books by himself.

"Wait, How did you know my identity? My fingerprints shouldn't be the same, right?" Yun Lintian suddenly thought of this problem. Theoretically, he was transmigrated here. His body shouldn't be the same as he was on Earth. Then how did the A.I. recognize him? Unless… He was still the same person for all this time! But how!? If that was the case, it also explained why he had the necklace with him.

Yun Lintian's mind spun rapidly. Several hypotheses appeared in his mind, but he didn't know and how to prove them. He concluded that the mysterious woman who brought him to the Misty Cloud Sect should be his old man's subordinate or friend. Was his old man omnipotent to the point he could reverse death? He was sure that he was already dead for good at that time.

The more Yun Lintian thought, the more confusing he became, as he lacked evidence and information. Everything was limited to his imagination right now.

"I cannot answer you, Master." Smart01 replied plainly.

Yun Lintian was disappointed, but he didn't ask further. He changed the topic. "Can I change your name? I don't like your current name."

"You can, Master." Smart01 replied.

Yun Lintian thought for a moment and said, "I'll name you Lynn then."

"Understood. From now on my name is Lynn." Lynn responded with a hint of excitement in her voice.

Oh? Does it have emotion? Yun Lintian was surprised. "Alright, please introduce this place to me."

"This place was built three thousand years ago…" Lynn started to introduce but was interrupted by Yun Lintian.

"Just get to the point. What are these books." Yun Lintian looked at the books on the bookshelves.

"Okay, Master. Currently, there are 874,325 books in this library. They are profound arts from all over the multiverse, classifying into 7 ranks namely, Primordial rank, Supreme rank, Divine rank, Mythical rank, Heaven rank, Earth rank, and Mortal rank."

"There are totally 4 categories, Body Refinement Art, Essence Profound Art, Soul Profound Art and Knowledge category. Master can ask me for a recommendation and I will sort everything according to Master's current level."

Yun Lintian nodded his head calmly. But his mind was in a mess… How did my old man collect all of this? What is his identity exactly? He asked, "Is my father built this place? And how did he collect these books?"

"It's your father, Master. However, I cannot tell you specific information because it was deleted by him." Lynn replied.

Tsk, this smelly old man. Yun Lintian was disappointed. He put this matter aside and asked. "Can you recommend me a profound art that suitable to my current level?"

The next moment, a few names appeared on the screen, sorted by rank and category, and there were aisle numbers behind them.

Yun Lintian looked at the names and was stunned for a while because they were too few, and none were higher than the Heaven rank.

"Just this?" Yun Lintian asked.

"Yes, Master. According to your current talents, these profound arts are your limit." Lynn replied softly.

Yun Lintian was speechless and carefully looked at the profound arts on the Heaven rank. There were only four of them, and all of them were mainly focused on the fire element… Without The Sun, I probably can't even practice an Earth rank's profound art? Before then, my talent is literally the lowest of the low. He thought.

Yun Lintian sighed and asked, "How did you evaluate my talent?"

"Mainly from your Profound Vein and constitution, Master. As for other variations, such as comprehension and soul power, they cannot be measured by me. Therefore, I will always provide every book without concerning your comprehension." Lynn explained.

"So there is a chance I cannot practice it, even though it's suitable to my Profound Vein." Yun Lintian understood the point. Lynn would give him a Primordial rank's profound art if it was suitable to his Profound Vein and constitution, but it still depended on his comprehension and other variations to learn it too.

"That's right, Master." Lynn said.

Yun Lintian didn't linger on this topic further. He asked, "Can I move this library to other places?"

"You can, Master. You can inject your profound energy into this monitor and the library will reduce into a small ball of light. Master can put it to any place you want later. However, Master cannot bring the library to the outside world." Lynn explained.

Yun Lintian nodded and said, "Alright, I'll go back first. See you later, Lynn." He remembered this was not the time to stay here further, as his sect was probably under attack at this moment.

"Have a safe trip, Master." Lynn replied, and the screen returned to normal with the welcome text.

Yun Lintian walked out of the library and opened the silver gate, leaving the Land of Beyond Heaven.

"Lintian!" Upon Yun Lintian appeared in the river, Yun Huanxin's Spiritual Sense immediately captured him. She was confused why he appeared here out of nowhere, but she cared more about his safety.

"Third Aunt?" Yun Lintian was surprised to see her.

"Are you hurt?" Yun Huanxin produced an invisible hand to lift Yun Lintian out of the river and asked with concern.

Yun Lintian shook his head, "I'm fine, Third Aunt." In fact, he was certain that his bones were broken, but it seemed he was healed by the Profound Spirit Lake.

Yun Huanxin didn't ask further as she said with a severe expression, "We need to go back now. The situation over there is not optimistic." In the end, she didn't dare to tell Yun Lintian about Yun Qianxue's current condition.

Yun Lintian's expression changed and hurriedly said, "I will set the formation now. Please help me make a cave here, Third Aunt."

Yun Huanxin shot a sword light at the cliff, creating a small cave within a minute, and brought Yun Lintian into the cave. The latter quickly set up the transmission formation and concealment formation. A half an hour later, both of them vanished into the transmission formation.

***

In the sky above the Misty Cloud Peak, Qi Qianxing leisurely sipped a spirit tea with no hurry to attack the Misty Cloud Sect.

"Your Majesty, there's a situation at the mythical realm's entrance." Suddenly, an old man with a white beard appeared beside him with a serious expression.

Qi Qianxing's brows raised slightly. "What is it?"

The old man began to narrate the report he received from Qi Hao.

Qi Qianxing frowned and put the teacup down. "Yuanfeng failed to capture him?"

The old man bowed his head and said nothing.

Qi Qianxing pondered for a moment and waved his hand. "Never mind. We can start now."

"Understood, Your Majesty." The old man bowed his head and called ten-odd people behind him over, starting to attack the Grand Protection Formation's barrier.

Boom! Boom!

Each attack was powerful enough to create a large hole in the barrier. However, none of them could completely deal permanent damage, as the barrier recovered almost instantly.

In the main hall, Yun Ruanyu wore a severe look on her face as she gazed at the barrier worriedly.

"Sister Ruanyu, we can hold at most an hour." Yun Qingrou said after checking the remained Profound Stones.

Yun Ruanyu was silent for a while before she said, "I am going to use The Final Haze."

Yun Qingrou hurriedly said, "Don't, Sister Ruanyu. We should wait for Sister Huanxin and others first."

Yun Ruanyu turned to look at Yun Qingrou and Yun Qianxue, who was unconscious on the ice bed. She said solemnly, "I'll stall them before Sister Huanxin comes back."

Yun Qingrou said nothing to persuade Yun Ruanyu further, as she knew eventually they would have no choice but to use The Final Haze.

Yun Ruanyu took out a brand new Guqin and headed out of the hall under Yun Qingrou's sad gaze.

Woosh—

Just as Yun Ruanyu was about to fly up, she noticed a fluctuation around the transmission formation.

"Sister Ruanyu!" Yun Huanxin appeared nearby the main hall with Yun Lintian.

"You're back." Yun Ruanyu said and looked at Yun Lintian. Seeing he was safe and sound, she was relieved, but the heaviness in her heart did not dissipate away because she didn't know what would happen if Yun Lintian saw Yun Qianxue's current appearance.

"Aunt Ruanyu, where is mom?" Yun Lintian asked as he didn't see Yun Qianxue even though the sect was bombarded by the enemy at this moment.

Yun Ruanyu's hands trembled slightly, and she said, "Your mother is inside. Go and take a look."

Yun Lintian noticed Yun Ruanyu's hands, and he had a bad premonition. Without wasting time further, he rushed into the hall and saw Yun Qianxue lying on the ice bed, unconscious.

"Mom!" Yun Lintian exclaimed and arrived at her side. Currently, Yun Qianxue had already lost all of her former devilish beauty. Her hair turned white, and there were wrinkles all over her body. She appeared to be a woman in her sixties.

With a glance, Yun Lintian could see her Profound Vein's condition as well as the vitality within her body. Without a doubt, Yun Qianxue had no more than ten years left in her.

Yun Lintian's eyes turned bloodshot. His hands were clenched into fists tightly to the point that blood dripping out. A strong killing intent was enveloping his body. At this moment, he was outraged — this was the first time he was angry for real since he came to this world.
